Tak

Due to her special condition she is not able to learn martial arts but it is believed that if treated her potential is unimaginable. In her reappearance an amazing progress is revealed.[2]

* **Nine Yin Body Type**: She was born with this condition, which blocks all nine of her Ki channels and makes her appearance look younger than she actually is because it slows down her physical growth. Her condition means that she is unable to circulate Ki properly and cannot practice martial arts. It is believed that curing the disease would give one the ability to master godly techniques, unattainable by humans. In The Breaker: New Waves chapter 86 she shows an amazing strength, killing Black simply by touching him in the right hand. Whether she is completely healed or not is not yet confirmed.

### Techniques Edit

* **Desiccation Technique**: A killing technique of unknown origin that So-Sul obtained after having some of her condition healed where by touching a person and perhaps directly channeling her Ki into them, she can dehydrate their bodies which caused them to mummify and eventually die as a withered corpse.
* **Walking Techniques**: When So-Sul begins killing Black for proving her power and Bae-Seung for harming Shi-Woon, she appeared immediately at their sides without the either of them being able to react despite their distance being a mere few feet apart..
* Expert Martail Artist (Chain-Sickle Style): She is highly skilled in martial arts and she is an expert in Chain-Sickle style. Her martial arts are long range and her weapon of choice is an Chain-Sickle. Her chain-sickle has claws instead of ball of weight. She seems very proficient with it since she can freely control it regardless of its length. she is also proficient enough to use it for defense in close range attacks. Her previous school before joining Soldiers Under Command is unknown.

TechniquesEdit

Chain Shield: Ji-Woo wraps the chain around area of her choosing to protect herself from an incoming attack.

Walking Techniques: She can use her school style of walking techniques to evade incoming attack, her exact mastery is unknown.

* The cases differ depending on which side has the issue, the Body or the Ki. A different issue in one side can have a different impact on the other.Although, this does not only refer to negative issues but also positive issues and impacts.

Body -> KiEdit

The relation between Body and Ki gives the ability to change the Ki by changing the body.

Final Step of Training: The Body and Ki relation is more visible by the martial arts training itself. There is a limit to the level of strength humans can achieve with their Ki amount and the Ki center in everyone is about the same. However, humans have discovered that by changing the body the Ki changes as well. With the final step of training people widen their blood stream which is the part of the body with the most Ki flowing in it. This results in the increase of the Ki amounts, in order to fill the empty space in the veins, and the increase of the size of the Ki-center, to hold the larger amounts of Ki, and, as a result, the increase of the individuals strength and potential.

Ki -> BodyEdit

Yin Body Type Explained

The reversed relation is also possible. The Ki and body exist in a balance. This means that a strong Ki needs a strong body to hold it. If this balance is lost then the body will break down and result to health problems or even death.

Hwan Gol Tal Tae

Yin Body Type: The Yin Body Type is an example of blocked flow of the Ki. There are Nine-Yins in total and the number of blocked Yins determines the name of the Yin Body Type. When some (one-to-nine) Yins are blocked the natural flow in the body is distorted or completely blocked. This affects the balance of the Simgichehon and the individual has health problems. The severity of the health problems is equivalent to the Number of blocked Yins. In addition, if not healed the person cannot control the Ki properly and thus is unable to use martial arts as well. In contrast, if healed then the individual becomes much stronger than the average person in terms of potential. The One Moon Divine Dan has been proven capable of unblocking the blocked Yins.

Overhaul Rebirth (Hwan Gol Tal Tae): The increase of the amount of Ki can change the body. Excessive amounts of Ki in the body rearranges the physique and bone structures as well as the organs. Although this is a very rare phenomenon and is usually called a miracle.

Martial ArtsEdit

Martial arts are closely related with the domain of Medicine as well and they are the starting point of the Science from the belief that humans can affect the body through the Ki.

TechniquesEdit

Techniques for healing are also existent:

Inner Energy Healing: The user transfers his/her own Ki to another person in order to enhance the healing of that person.[1]

ScienceEdit

The existence of Ki extents even as far as the Science of Medicine. Clans and Schools focus on controlling the Ki for healing purposes. Others study it further to enhance other factors as well. The most notable are the One Moon School and the Blood & Bone School. Starting by researching the and experimenting on Ki to improve their strength in the Murim they managed to learn the medical uses of Ki as well.

Schools/ClansEdit

One Moon School: The greatest, at the moment, medical center belongs to the One Moon School. They have researched for many years on the ways of the Ki and have learned healing and treatment ways that are generally not known in the Murim. They are capable of treating a broken Ki-Center that was thought to be impossible and are capable to hold in comatose state a person that was shot in the head.

Blood & Bone School: The Blood & Bone School focused on the use of Ki to permanently enhance certain functions of the Human body. Seung-Jae is the first and only example of this having enhance his vision to the point of reaching the level of night vision (Yah Myung Ah), although he lost his hair in the process and has now resorted to wearing a wig. In addition this school also has a history on pills related to Ki. Also, Seung-Jae was able to make a cure for the Nine Yin Body which was said to be incurable hinting that the school managed to find a cure.

Mil-Yang Clan: Although not an especially long history with medicine the Mil-Yang Clan has shown skill in medicine by creating an improved version of the Ma-Hwan Dan, the Jin-Gi Dan.

Heung-In Hospital: The Heung-In Hospital specialize in Ki healing. Currently their head, Ju Sang-Sik is treating Kang-Sung, who suffered critical internal injury after his fight with the Nine Arts Dragon. Also, the good doctor manage to heal Shi-Woon's mother who was in comatose state and other doctors were not sure she could wake up.

Spirit MedicineEdit

Main article: Spirit Medicine (Dan)

The Medical Sciences even reached as far as the physical form of pills that had a direct effect on the Ki. These pills were named Spirit Medicines since based on the Simgichehon the Ki is the Spirit of the body. Each pill has different use and different effects and side-effects. Their use is not limited to the health issues but extends to the human desire for power. Known medicines are:

Il-Wol Sin-Dan (One Moon Divine Medicine)

Hwan Dan (Circulation Medicine)

Ma-Hwan Dan (Evil-Circulation Medicine)

Jin-Gi Dan (Accelerating-Ki Medicine)

Bo-Hyul Dan (Blood Supplement Medicine)

* **Spirit Medicines** are, as the name implies, medicines for one's spirit (Ki). They are the result of development of the medical science in the field of Inner Energy. The common trait of all known Spirit Medicines is that they can affect the Ki of an individual in order to bring the desired result for the body.
* TranslationEdit

The Dan is translated into two different ways, depending on the case, Pill and Medicine. Since the Medicine is also used with the meaning of Pill, they are synonyms, thus use of either of the two is valid and does not change the meaning of Dan.

UsageEdit

Spirit Medicines have been shown to be a rare category even within the Murim. However, they are widely used. Among them are common pills that are used for medical purposes. The most rare pills, which are usually the most extreme, are used to strengthen or increase someone's Ki, to give a boost in strength or even to control people.

Known Spirit MedicinesEdit

One Moon Divine Dan

The most powerful spirit medicine: Il-Wol-sin Dan

Il-Wol Sin-Dan (One Moon Divine Medicine)Edit

The greatest creation of the medical sciences in the whole Murim. There are said to be only three pills in the entire Murim and the cost for each one is one billion won (assumed currency). Upon ingestion the pills causes the body to create limitless amounts of Ki resulting in the break down of the individual's body and death. The only known way to control the pill's Ki creation is the use of advanced Ki distribution techniques such as the Black Heaven and Earth Technique. If the techniques are used and the Ki is stabilized in the body then the person immediately has the potential to become a Real Master because in order to hold the infinite amounts of Ki the use of the Black Heaven and Earth Technique causes the same change in the body as the fourth and final stage of training. It is also the only known confirmed cure of the Yin Body Types. This is probably because since the pill creates so much Ki the areas that are blocked from Ki distribution are forced opened and the formerly supressed Ki begins circulating.

Hwan Dan (Circulation Medicine)Edit

According to Shi-Ho it helps circulate the Ki of the individual who consumes it.[1] It has never been seen used.

Ma-Hwan Dan (Evil-Circulation Medicine)Edit

Seung-Jae Bae was able to create a spirit medicine that maximizes the amount and quality of the Ki circulating around the body while it activates the circulation of Ki with an explosive effect enabling an individual to use martial arts even with a broken Ki-Center.[2] However, the pill's function is temporary and it's explosive effect causes afflictive after-effects like excessive fatigue and an over-heating of the organs.[3] The person who consumes them cannot stand up properly with exceptions being individuals of high stamina. There seem to have been various versions of the Ma-Hwan Dan:

The first Ma-Hwan Dan was applicable only to people that already use Ki. [4]

The S.U.C.'s initial Ma-Hwan Dan allowed Murim-ins and normal people alike to use high level techniques by activating their Ki. [4]

Later on, S.U.C. started to use a Ma-Hwan Dan that not only enabled the use of martial arts for murim-ins and normal people alike, but also capable of controlling people's minds. People who ingest become confused and easily manipulated [5] resulting in them being brainwashed as well as showing more violent behaviour.

Jin-Gi Dan (Accelerating-Ki Medicine)Edit

The Jin-Gi Dan is the spirit medicine made by the Mil-Yang Clan and is an improved version of the spirit medicine, Ma-Hwan Dan, created by Seung-Jae Bae. Just like with the second version of Ma-Hwan Dan, by ingesting this pill an individual is capable of using martial arts even with a broken Ki-Center. The difference is that this accelerates the Ki and does not have the explosive effect of the Ma-Hwan Dan. The after-effects are seemingly non-existent and the effect of the pill lasts longer than its predecessor.

Bo-Hyul Dan (Blood Supplement Medicine)Edit

The Blood Supplement Pill, created by the One Moon School, as the name suggests, is a pill that speeds up the body's mechanism for the creation of blood by temporarily activating the Ki.[6]

Sedative PillEdit

A form of sedative that enables someone to suppress memories that they wish to forget. [5] Although, it also seems to make someone more obedient towards certain individuals and their instructions which gives it a brainwashing effect. There is implication that this sedative relates to the Ma-Hwan Dan due to its effect on the individual's behaviour but nothing is yet confirmed.

* -Wol Sin-DanEdit

Shi-Woon Yi: Shi-Woon was given the Illwallsidan by Shi-Ho Lee. Due to ingesting and processing this pill Shi-Woon Yi's body is now a spirit medicine in and of itself after managing to control it with the assistance of Chun-Woo Han and the Black Heaven and Earth Technique. It has been hypothesized that anything but a fatal injury would be healed overnight.

Jang So-Sul: Although hasn't eaten it herself, So-Sul has also witnessed the effects of the One Moon Divine Dan (Illwallshidan) through Shi-Woon's blood given to her in an effort to help her after she had a shock attack due to her condition. Until that moment she was unable to even talk a lot and was easily getting tired but after drinking some of Shi-Woon's blood her condition improved to the point that she could converse normally and her stamina had clearly increased.

Ma-Hwan DanEdit

Shi-Woon Yi: He was given the pill by Seung-Jae Bae while he was looking along with Jang-Il Jeong for a way to get stronger when he was unable to use martial arts due to his broken Ki-Center.

Chang-ho: He was given the Ma-Hwan Dan by the S.U.C. enabling him to use Ki-based martial arts at the cost of his own health.

Soldiers Under Command: They used an enhanced version of the Initial Ma-Hwan Dan that literally activated the Ki in a person's body, enabling even normal people to use high-level techniques. They later, enhanced it further, giving it effects that allow them to control their follower's minds and construct their behavior as they wish. [4]

Jin-Gi DanEdit

Shi-Woon Yi: Shi-Woon is the only known user of both the Ma-Hwan Dan and Jin-Gi Dan. After he accepted the help of the Mil-Yang Clan he was given this pill after experimenting on the Ma-Hwan Dan. He used it later on to defeat Yong-Hyun Yan while protecting Jin-Ie Kwon and for his training after that because his Ki-center was broken during that period.

Bo-Hyul DanEdit

Shi-Woon Yi: When Shi-Woon was caught by the S.U.C., through Seung-Jae Bae, and was almost made into a medicine, Sera Kang went to his rescue and gave him the Bo Hyul Dan to help him restore his lost blood. This makes him the only known case. Although, the effect of this Dan implies the possibility of its not-so-rare use for medical purposes.

Sedative PillEdit

Chun-Woo Han: The pill was given to Chun-Woon by Sophia in order to help him forget his painful memories. Although the pill also made him more obidient to other people's intractions showing that it has the effect of brainwashing. [5] This effect made people believe that Chun-Woo was given the Ma-Hwan Dan [7] although a relation between the two medicines is possible.

* Inner Energy or Ki is the energy within every human which is commonly used in the Murim world as the primary way of fighting. It is also referred to as "Breath" and "Life Force". People that learned how to control and use it created the world of Murim.
* SimgichehonEdit

Main article: Simgichehon

Simgichehon is the basic composition of a person.There are four parts to it:

Energy Absorption Great Technique (Huep Jeong Dae Gong): This technique allows the user to absorb the Ki and life force from the opposite sex, living them in a mummy-like state, in order to increase his own Ki.

Unnamed Skin Technique: He uses a technique similar to Iron Body Technique but he refers to it as being impervious to steel. The only weakness are the genitals.

Sim (Mind) is the ability to think. The use of the brain to send orders to the whole body.

Gi (Breath) or Ki is the life force in all creation.

Che (Body) is the materials that make up the body. For example, muscle and bones.

Hon (Spirit) is the will of a person and desire to achieve something.

These four aspects of the bodies composition are tied with one another and must be in balance. Irregularity in one of them can cause problems in the function of the rest.[1]

Real Master Martial Artist (Black Heaven and Earth Style): The dominant martial artist of his generation. Un-Wol was extremely skilled, easily dispatching Jae-Myung Cho, the Iron Fist Munju. He was able to throw him a great distance with relative ease with one arm right before the former was able to react.[6]

Real Master Martial Artist (Heavenly Way Style): So-Chun is considered a genius who has mastered the 5 forms of Heaven's Will.[4] As is expected of someone of his position his distribution of Ki is natural. He can stop a punch strong enough to break stone with relative ease. He is fast enough to execute moves that are difficult to react to. He is strong enough to crush a wooden board by compressing both ends, causing the wood to unravel into shreds.[5]Chun-Woo himself described Hyuk as someone who reached the top of the martial arts world. It is also shown that he was able to hold himself fairy well against Goomonryong while he was in Black Origin Threshold state, which amazed the witnesses. However he himself admitted that the damage of his attacks were superficial at best and was eventually overpowered by Goomoonryong even when he was fighting with three of the Five Protectors of the Heavenly Way.

Martial Arts Prodigy: In the beginning Shi-Woon appeared as a non-talented individual in terms of learning Martial Arts. However, after healing his Three-Yin Body Type and started training he was revealed to be far more gifted than he seems. He displayed observation skills of an extremely high level. This has been shown various times throughout the series. He was able to learn how to use Soul-Crushing Strike in half a day and the Walking Techniques after one night. Chun-Woo Han was astounded with both cases as normal people take several months to "only" understand how the same techniques work. Equally astounded Kang-Sung commented that Shi-Woon may be a "dragon", just like his master. Additionally, he was able to learn and enter the Outer Body Training Method after one day of training, something that takes a year for talented individuals and an average of five years for normal ones. Lastly, he was able to learn all the Black Heaven & Earth School and Nine Art's techniques he knows from videos left to him by his former master and without proper instruction from anyone. Many Murim-ins, especially highly experienced masters, that observed his fighting outright believed and claimed that the information of him practicing martial arts for just a few months at best to be false due to his abnormal and supernatural progression in martial arts. Also a great deal of them, in particular So-Chun Hyuk, declared that they wish to see his future as a martial artist. A testament to Shi-Woon's incredible talent in martial arts is that he is the first and only person that So-Chun Hyuk ever thought of becoming his rival a position that his own senior, So Jung Chan, has not even earned himself. Recently when Shi-Woon instinctively invoked the Cry of the Phoenix technique over Elder Kwon's death like Chun-Woo Han did over Shi-Ho's apparent death, he had invoked a different form of the Black Origin Threshold. This led Kaiser, the leader of the Black Forest Defence, to state that Shi-Woon would become a greater "Demon King" than his master.

Real Master Martial Artist (Black Heaven and Earth Style, Nine Arts, Sun-Woo Style, and Artists' Society Style): His actual rank has never been clearly stated but it can be identified through his fights so far. In terms of Spirit, he is shown to have one on the same level as his master thanks to his resolve (death or victory) since he entered the Murim. His Ki was equally high level due to the ingestion of the Il-Wol Sin-Dan and assimilation of it using the Black Heaven and Earth Technique. This, additionally, increased the size of his meridians, which is the last step of training in order for a Murim-in to reach the Real Master Level. This along with his abnormal observational skills allowed him to grow in a speed that even experienced and great Murim-in cannot comprehend.

Rank Succession: Normally a murim-in grows with time and training and passes through set ranks as one develops. However, in Shi-Woon's case there is no clear point that determines his passing from one rank to the other because of his unnatural training and development. Hence, his rank succesion will be estimated based on the series' events and comments from Murim-ins.

Practitioner: Due to his Yin Body Type his body was weak and unable to learn Martial Arts. By ingesting and assimilating the Il-Wol Sin-Dan not only was his condition cured but his Ki reached the level of Real Master while his physical body was still weak. Within a few days he managed to stabilize its circulation and after several days his body was starting to catch up through basic physical training. After learning the Soul Crushing Strike and fought against So-Chun Hyuk, who called him skilled, it is assumed that he is already a practitioner.

Expert: Within a couple of weeks Shi-Woon was able to catch off guard and defeat Kang Oongsan, who is stated by So-Chun Hyuk to be an expert in a specific style with one attack. Hours later, while running from the Martial Arts Alliance he was reported as an expert due to his skill of using Soul-Crushing Strike and Walking Techniques.

Master: After learning and training with the Outer Body Training Method, Shi-Woon was able to hold his own and, by catching of guard, defeat Yong-Hyun Yan, who, according to Jae-Kyu Kwon, is a master rank Murim-in. Later, after training using the Jin-Gi Dan his skills improved again. Although injured and tired, he was able to fight equally with Yong-Hyun Yan and defeat him a second time. This is the point of his transition to a Master.

Advanced Master: During the invasion of the Nine Dragons High School by the S.U.C. he has learned how to efficiently use the minimum possible Ki and produce the best possible outcome with it, which surprised even Ha-ru. By entering into Black Origin Threshold he was able to land strikes against Ryuji, who was able to fight against Jae-gal (a real master). After he healed and his body underwent Overhaul Rebirth his skills (fighting against Jung Lae Won and Ju Sang-Sik after defeating numerous agents and losing lots of blood) reached the level of Advanced Master.

Real Master: After training with the Triple Blossom Meditation Technique, where he continuously sparred with So-Chun Hyuk, a renowned genius even among the Ten Grand Masters, his skills improved greatly. He was able to easily defeat the Murim Police Chief with just two attacks while the latter's disciple, Jung Lae Won, was unable to land a hit on the former and was easily defeated. Later he fought against Ha-ru, Yong-Hyun Yan and Ji-Woo Li (three of the S.U.C. captains) simultaneously and was able to hold his own despite being exhausted from fighting the grunts of the S.U.C. earlier. His skills also surprised Chun-Woo Han and Advanced Masters, such as So Jung Chan and Julia, were unable to comprehend his techniques. Also during his fight with So Jung Chan, Shi-Woon displayed greater observation skills as he was able to easily counter all of the former's attacks and even copied a counter technique that So Jung Chan demanded to know where he had learned it. Upon activating the Black Origin Threshold from Elder Kwon's death in a new form, Shi-Woon is able to fight evenly against his master, Chun-Woo Han, displaying the same level of power Goomoonryong has and managed to push him back a few times (though Ju Sang-Sik and Kang-Sung noted that Goomoonryong wasn't going all out) but he was eventually subdued. Despite this, many of the witnesses (including Ju Sang-Sik and Te Ul) admitted that had Shi-Woon learned martial arts properly after undergoing the Overhaul Rebirth then he would have defeated his former master in that fight. This is assumed to be the point of his transition to Real Master.

MentalEdit

Goomoonryong-Level Spirit: Even in fights where the odds are against him, Shi-Woon has displayed an indomitable will and not backed down from a fight since receiving his first, albeit offhanded, lesson from Goomoonryong. Whether it is bravado, stupidity, or a mixture of both, Shi-Woon's willpower has impressed many martial artists, including So-Chun Hyuk. Instead of his unique techniques or Ki reserves it is his inhuman determination and spirit that most often convinces other Murim-in that he truly is the disciple of Goomoonyrong. Recently So-Chun Hyuk stated that Shi-Woon is the superhuman that surpassed the instincts of mankind which allows him to terrify others with his spirit alone rather feeling fear himself. Ju Sang-Sik also commented that Shi-Woon is crazier than his own master, Goomoonryong, which also hints at this form of spirit.

PhysicalEdit

Superhuman Healing Factor: By ingesting and assimilating the Il-Wol Sin-Dan, Shi-Woon received Ki equivalent to several of the top martial arts masters [1]. His body became a living spirit medicine and developed a healing factor that, according to Chun-Woo Han, rivaled the Planaria [2] and this allows him to heal any non-fatal injuries within half a day and any level of fatigue will disappear overnight. Seung-Jae Bae had declared Shi-Woon to be a "walking" spirit medicine due to the excessive amount of Ki his body possesses that gives him an incredible healing rate that Yae-Won noted to be abnormal even by Murim standards. Seung-Jae also said that there are several places in his body generate Ki independently of each other which gives him the advantages of negating accurate point attack. Wounds from knives healed within the day and the injuries from his fight with So-Chun Hyuk within a night. Fatal injuries would still need medical assistance but from the moment his body is no longer at risk his healing capabilities will take over. Such injuries include the forceful removal of the Thousand Needle Restriction that Ju Sang-Sik used against him and the injuries from the Chaotic Heavens Destruction Strike. The later was an astounding case, since even with the medical assistance he recieved he was thought to be a lost case but showed a remarkable turn, healed in a few days and regained conscious. It is possible that, since during that time he underwent Overhaul Rebirth, his healing factor was enhanced as well.

Immense Endurance: Shi-Woon's stamina and pain endurance has surprised many top murim-ins including So-Chun Hyuk, Kang-Sung and Ju Sang-Sik. He is able to fight for long periods of time and stand up after recieving various blows from his opponents. Many comment on the impossibility of his endurance as in many cases he is supposed to have fainted or even died several hits before. When Shi-Woon had activated the Black Origin Threshold he was able to continue fighting even after being dealt with fatal wounds that terrified even the S.U.C. Recently after undergoing the Overhaul Rebirth and entering the Triple Blossom Medition, Shi-Woon is able to endure punishing strikes from even his own former master, Chun-Woo Han, and remained conscious despite the damage.

Enhanced Strength: Shi-Woon has blown apart doors of reinforced glass with a single punch after fighting for hours and ripped a car door off it's hinges without any effort. He managed to knock back and throw Ryuji a former student of Un-Wol through a window with ease. After undergoing the Overhaul Rebirth, Shi-Woon is able to send skilled Murim-ins like the Murim Special Ops agents flying back with simple punches and left many of them severely injured with one of them questioning if he was a monster. After using the Cry of the Phoenix and having activate a new form of the Black Origin Threshold, Shi-Woon displayed enough strength to push back his former master, Chun-Woo Han, with one punch which the latter was barely able to block (albeit the latter was caught off guard then). During their fight, Shi-Woon's attacks were able to demolish the surrounding structures similar to his master.

Immense Agility: Due to the natural strengthening of his body from Ki circulation Shi-Woon has supernatural agility. He is agile enough to fall from a height of 4-5 stories. Recently he has shown the ability to effortlessly flip and jump around a fight using most surfaces to his advantage.

Enhanced Senses: Since the Overhaul Rebirth, Shi-Woon has shown that, his body feels lighter and he is more sensitive to things around him. His five senses are enhanced making it possible for him to feel and hear things that should not be possible under normal circumstances. He is even able to tell how strong a person is and their intent towards him from their ki alone even if they are suppressing it. His reflexes have also increased dramatically to the point that his body acts without him realizing it.

Ki-Center State: After ingesting and assimilating the Il-Wol Sin-Dan his Ki-Center grew significantly. During his treatment to heal it and after the basic Ki-Center was formed, it was noted by Hyun Won-Jae that his Ki-Center tries by itself to grow bigger, something he had never seen before. During that time he was able to perform martial arts to a certain degree [3]. After undergoing Overhaul Rebirth it was completely healed by itself and it is assumed (based on the comments for his Ki by Ju Sang-Sik) that it has reached the size that it was attempting before.

Overhaul Rebirth (Hwan Gol Tal Tae): It is the phenomenon where excessive Ki within the body rearranges the organs, bone structure, and overall physique of the body. This phenomenon was witnessed on Shi-Woon while he was healing after the events of the Soldiers Under Command's invasion of the Nine Dragons High School [4]. It is assumed that this phenomenon was responsible for the complete healing of his Ki-Center. Ju Sang-Sik stated to Shi-Woon that undergoing this phenomenon gave him the potential to become the strongest master in all of murim even surpassing his former master, the Goomoonryong himself. When describing the effects of the Overhaul Rebirth to Shi-Woon, Ju Sang-Sik stated that Shi-Woon's body became more free and is no longer within the boundaries of human limits and said that in order for him to become stronger he needs to forget his former limitations. In other words he is now in possession of a "superhuman body" (as said by the ghost doctor) and can learn abilities normal people couldn't even imagine.

SkillsEdit

Stealth: Shi-Woon gained the ability to hide his Ki much more effectively than people who are above master level. This ability allows him to move around unnoticed and to hide from even experienced martial-artists as is demonstrated in the events following the S.U.C.'s attack on his school. Only grandmasters have been able to detect his presence.

WeaknessesEdit

Inexperience: Due to his lack of experience in fighting he is vulnerable against an opponent with more experience as shown with his duel with So Jung Chan over the fate of Seoul whom he noted to be below his younger brother in term of skills, but he had more experience. He is unable to use his skills and techinques to the best of his abilities. Only his master could teach him however they have turned into enemies.

Techniques Edit

Heavenly Way Punch: This technique is a Gwongyuk of the Heavenly Way School. The force of this attack is so great it can send an opponent flying and embed them into any physical structure the opponent crashes into. It is said that it is almost impossible to take the blow and survive.[6]

Foot Techniques: So-Chun has shown an amazing feat of superhuman speed, being able to catch up to and surpass a taxi Shi-Woon was in.[7]

Fierce Tiger Strike: When the practitioner withdraws the left hand the flow of Ki changes. Hence, in order to use it the practitioner must change the Ki-Flow and use a heavier Ki. The practitioner then punches forward. It is a Ki strike capable of effortlessly breaking a wooden stake in half.[1]

Silver Dragon Strike: A strike with throwing characteristics that sends the opponents flying upwards.[

TechniquesEdit

Black Heaven & Earth SchoolEdit

Main article: Black Heaven & Earth School

As the Master of the School Un-Wol is believed to have mastered all techniques of the School.

Black Heaven and Earth Technique: A special Ki circulation technique which Un-Wol taught to his disciple, Chun-Woo. It is considered the ultimate technique in the Murim world and is the cause for all events in the series due to it's power.[2]

Black Origin Threshold (Hyun Wonji Gyung): is the purest form of the Black Heaven & Earth Technique. The user is granted immense strength, beyond that of normal human capability, at the cost of rational thought. When using this state, Un-Wol was able to defeat and kill a large amount of Murim elders, leaving none alive.[2]

Gale Wind Destruction Strike: It is a Ki-strike with a whirlwind like effect that sends the receiver of this technique flying while whirling around in a spiral pattern. A successful direct attack with this technique is supposed to make the internal organs explode ensuring the death of the target. According to Ryuji it is the strongest Ki-strike. It is one of the techniques that belong to It belongs to the Black Heaven & Earth School's martial arts and was taught by Un-Wol to Ryuji.[7]

Walking Techniques: His walking techniques are unique in that they create air pressure around the user when upon execution. It belongs to the Black Heaven & Earth School's martial arts and was taught by Un-Wol to Ryuji.[7]

Chaotic Heavens Destruction Strike(Hon Cheon Meol Gyuk): It is the most powerful technique of the Black Heaven and Earth Technique. It belongs to the Rising Fist Arts and, hence, the user must take three steps back to execute the technique

Ki FlowsEdit

Natural Ki FlowsEdit

The Ki follows a natural flow throughout the body and is as important as the other three aspects of the body's composition for the appropriate function of the body. An irregular or blocked natural flow can affect the function of the body and cause health problems. The Yin Body Types are an example of blocked flow of the Ki. The blockage cause an unbalanced state and, if not healed, the person cannot control the Ki properly and thus is unable to use martial arts while has health problems at the same time.

In the case of the Black Origin Threshold the natural flow of the Ki is reversed causing the individual to enter an unconscious state where the body moves based on instinct alone using the Ki as guide.

Amount & Use of FlowsEdit

The natural flow consists of more than one flow of Ki and, more accurately, three different flows.[2] The different flows of Ki determine also how heavy the Ki is.[3] The flows of Ki play an important role in the execution of seemingly high-level techniques. In some techniques, like the Fierce Tiger Strike the user must change the flow of Ki in order to execute them.[3] There is also the case where all three Ki flows must be used for the execution of the Chaotic Heavens Destruction Strike.[2]

UsageEdit

Ki-CenterEdit

Ki and Ki-CenterEdit

The Ki-Center is located in the abdominal region. It is a point that allows the individual to control the circulation of Ki in the body by affecting its natural flow. Although it is not made of solid matter but from pure energy it is possible for the Ki-Center to break. However, a broken Ki-center does not affect the natural flow of Ki and does not cause problems to the body's function but it renders the individual unable to sense and control Ki.

Broken Ki-CenterEdit

If broken once then there is a special treatment that can bring it back together allowing the individual to control Ki once again. However, if it breaks a second time then the state becomes permanent and treatment is as of yet considered impossible. Normally to identify if the Ki-Center of an individual is broken a certain order of check-ups is required. However, it is also possible to know if an individual has a broken Ki-Center by feeling the pulse. Jang-Il Jeong was seen doing it so it is assumed that someone must be a master on his level.

Size of Ki-CenterEdit

The size of the Ki-center is the same for every person but as the individual trains in the ways of the Ki and increases its amount then the size of the Ki-center will increase as well. The bigger the Ki-center and the amounts of Ki, the stronger the individual is.

ExceptionsEdit

When the Ki-center is broken controlling Ki is impossible. Exception to this however is the Ma-Hwan Dan, created by Seung-Jae Bae, and its improved version, the Jin-Gi Dan.

ControlEdit

Main article: Martial Arts

An individual can learn how to control the Ki through training in the ways of the Ki. The training consists of four steps.

The first steps of training focus on breathing exercises that help the person control the flow and circulation of the Ki in the body by learning how to use the Ki-center. The main idea is to gather the Ki to the Ki center and then distribute it evenly to the whole body. This step includes applying circulation and distribution techniques.

As the circulation training proceeds the individual will have to start physical exercises in order to keep the Ki and the physical body in balance.

The third step involves exerting the Ki to enhance the body's functions and movements. The result is the use of martial arts, increase to a certain level the healing speed, becoming able to see the Ki within the surrounding environment and so on.

After the individual reaches the third step then the three steps are still done simultaneously in a pre-organised training program. With this training a person can reach the level of Master.

The fourth and final step of the training focus on surpassing the body's potential. It is also called the highest level of training. An individual widens his bloodstream which has as a result the further increase of the Ki amounts and the size of the Ki-center. The result is that the individual can reach, what is called as, the level of a "Real Master".[4]

(Taking a Spirit Medicine however can distort the order of training while it endangers the practitioners health.)

Natural PhenomenaEdit

The cases differ depending on which side has the issue, the Body or the Ki. A different issue in one side can have a different impact on the other. Although, this does not only refer to negative issues but also positive issues and impacts.

Body -> Ki: The relation between Body and Ki gives the ability to change the Ki by changing the body. One such example is the Final Step of Training where the Ki reserves increase by widening the blood stream.

Ki -> Body: The reversed relation is also possible. The Ki and body exist in a balance. This means that a strong Ki needs a strong body to hold it. Issues with the Ki (positive or negative can affect the body. Such examples are theYin Body Types and the Overhaul Rebirth (Hwan Gol Tal Tae).

Martial ArtsEdit

In Martial arts there are techniques, like the Inner Energy Healing[5] that can affect the body by using Ki.

ScienceEdit

The existence of Ki extents even as far as the Science of Medicine. Clans and Schools focus on controlling the Ki for healing purposes. Others study it further to enhance other factors as well. The most notable are the One Moon School and the Blood & Bone School. Starting by researching the and experimenting on Ki to improve their strength in the Murim they managed to learn the medical uses of Ki as well. Such an exmaple are the Spirit Medicines/Pills (Dan).
