General Concepts in Tensei Shitara Slime Datta Ken (Web Novel)

This will go over some general concepts in Tensei Shitara Slime Datta Ken.
==Ultimate Skills==
Ultimate Skills in tensei makes the user resistance to the abilities of skill below them.
This is brought up when Clayman thought his Unique Skill Puppeteer which attacks its targets soul and then completely controls them, was able to control Milim Nava. To which Gii Crimson basically laughs at the idea of a Unique Skill working on someone with an Ultimate Skill:
This is again reiterated in chapter 187:
And stated again in chapter 210
So it's pretty obvious in this series that unless you have an ultimate skill, magic doesn't work on them, this gives them resistance to various abilities such as Soul Manipulation, Mind Manipulation, Matter Manipulation etc, as those abilities have been shown to be possessed by people who aren't ultimate skill users. Which makes sense as Ultimate Skill users understand the laws of the world and are thus superior in using magic than people who aren't Ultimate Skill Users:
Additional ordinarily stealing an ultimate skill from its user is normally impossible as the skill is born from their soul and exists within it:
Ultimate skills don't require an incantation:
==Ultimate Skill Users==
Ultimate Skill Users can give fake info about themselves.
Can conceal info about themselves
Can know if they are being analyzed:
Can't be analyzed by skills below their level:
==Turn Null==
Turn Null is the energy that was used to create the world:
==Mana Breeder Reactor==
This allows the user to continuously create mana:
==Primative Magic==
Primitive magic is the source of all magic, and can even affect those who have ultimate skills:
==Veldanava and the System of the World==
Veldanava created several parallel worlds after being bored in nothingness:
However humans began to war because of emotions, so he created a system to manage them:
After the system was created, Veldanava fell in love, which caused an error in the system, thus the system decided to kill him:
==The Soul and Core==
The soul has multiple parts, the ego which is covered by the nucleic heart which is where all data is engraved, and the crystallization of energy around the nucleic heart forms the soul:
Nucleic Heart has been referred to simply as core on other occasions such as when Shion was revived from the dead:
When Rimuru wanted to free Veldora from Rudra's Control:
When Veldora gained the ability to leave his core in Rimuru:
When Leon's core was damaged but his soul was intact:
The Nuclei Heart has already been established above to be where all the data is engraved, so obviously if it's damaged Leon wouldn't be able to use control his powers.
The soul also has 3 layers:
==Spiritual Lifeforms==
Spiritual life forms don't have physical bodies, Benimaru when he became one lost his physical body:
Zegion as a spiritual life form has a body composed of water:
Leon became the holy aura within him when he became a spiritual life form:
Spiritual lifeforms can survive physical death:
High ranked spiritual lifeforms can move in stopped time:
Spiritual lifeforms don't have a lifespan:
Spiritual lifeforms are immortal and can't die unless their core is destroyed, which has already established to be within their souls:
Spiritual lifeforms can regenerate their cores as long as they are not destroyed, and again cores have already been established to be within their souls.
So what does this mean? Spiritual life forms have eternal youth and unless you destroyed their cores within their souls, will regenerate.
==Infinite Prison==
Chloe O’Bell used infinite prison to seal Veldora Tempest, this sealed him in imaginary space:
==Soul Corridor==
In order to escape Infinite Prion, the Soul Corridor was developed. Soul Corridor allows the user to be immortal as long as someone else exists:
This allows Rimuru to be immortal as long as one of his clones exist:
==Spirits==
The holy spirit is the source of power, that first existed and gave birth to spirits of light and darkness which came into existence the same time as the world. From them, the spirit of time and the other spirits were born:
The spirits are masses of energy:
==Demons and Angels==
Demons can manipulate minds:
Demons can teleport:
Demons exists as a mass of energy:
As spiritual lifeforms demons can regenerate:
Demons have no physical bodies in the underworld and receive power from the spirit of darkness:
Demons also don't have souls and only gain a soul when summoned into the material world:
Demons are also said to have been born conceptual existences:
Demons can resurrect:
Stated again to able to resurrect:
Demons are on the same level as spirits:
==Arch Demon==
Arch Demons are capable of destroying towns:
Arch demons are also stated to be comparable to tactical nukes:
==True Dragons==
True Dragons are spiritual lifeforms:
True Dragons exist only as souls:
 
True Dragons can resurrect:
Stated again:
==Food Chain==
The reason why Rimuru is so powerful, in short he can gain all his subordinates abilities:
In addition, Rimuru is always getting stronger:
This makes people who were previous threats to him, inferior:
==Ciel==
A skill that is apart of his soul that is made for analysis:
Ciel was able to synthesize the abilities stored in food chain which granted Rimuru new abilities, which allows him to do various things including creating new skills:
Ciel can even conceal the voice of the world, this is the same voice of the world that shows up every time someone gains a new skill or evolves, and as already explained above, it is the system that was set up by Veldanava to manage the souls of all dimensions:
==Information King: Akashic Records==
Yuuki Kagurazaka spent 1 month analyzing every ability in the series, and was able to use almost all of them except Rimuru's Turn Null and Milim's Mana Breeder Reactor
Why is this important? Because despite all those abilities Yuuki had to concoct an elaborate plan to send Rimuru to the end of space-time.
Yuuki says Rimuru is equal to him:
Yuuki despite all the abilities he had, was forced to use his trump card
Which is proven when Rimuru quickly copies and nullify's Yuuki's abilities:
Also as mentioned above Velda specializes in all ultimate skills, it just did not have the ability to replicate them, it was revealed previous that Velda was originally the skill of Veldanava, which means Veldanava had the ability to use all abilities, and Rimuru>Veldanava, plus Rimuru absorbed Yuuki and Velda was apart of Yuuki's soul, just like Ciel is apart of Rimuru's.
