Universe World

Alternatively referred to as a "**Great World**" by its inhabitants, or as an “**Inner Universe**” in the “Outer Universe,” a **Universe World** is one of the self-contained and complete Universes that make up a large part of the 3,000 Worlds. Each Universe World has its own unique, complete, and strong set of World Principles, as seen in the examples of Star Boundary and Demon Realm.

There are numerous Universe Worlds within the many different Great Territories of the Outer Universe, and they often have a 2nd Class or higher Outer Universe Influence to rule over them. However, some Universe Worlds, like Star Boundary before modern times, lay in forgotten, new, or isolated Great Territories and have no such Influence to rule over them. All Universe Worlds within the 3,000 Worlds receive their World's Will from the **World Tree** in Great Ruins Boundary, and they are originally born from the Universe Furnace that resides within **Chaos**.

The other type of Universe World is the **Small Universe** of High Rank Open Heaven Realm cultivators (7th-9th Rank).

## Standard Rules

### Great Emperor

Like all worlds, each Universe World has its own set of World Principles that determines its Heavenly Way. The World Principles can differ greatly between different Universes, but every real Universe World allows cultivators to at least reach the Emperor Realm. Many Universe Worlds have a limit by their Heavenly Way for allowing Emperors to both condense Dao Seals and transfer their **World Force**. These chosen cultivators are called **Great Emperors** in most Universe Worlds. Generally, Great Emperors can display the power of Low Rank Open Heaven Realm within their respective world. Though extremely rare, some Universe Worlds can allow their Great Emperors to display the strength of Middle or High Rank Open Heaven Realm (i.e. Star Boundary with World Tree Subtree).

#### Monster Race Great Emperor

Since the start of the Human Race Era, only the Human Race and their variants (ex: Demon Race) have been able to receive the acceptance of the Heavenly Way to achieve Great Emperor. However, this convention would finally be broken when Ying Bao, carrying the Divine Soul Clone of Yang Kai, became the first known Monster Race Great Emperor of the Era. The rules for a Monster Race achieving Great Emperor appear to be very different from that of Human Race cultivators. This is namely due to the fact that it is done during the breakthrough to Monster Emperor (equivalent of Open Heaven Realm), and does not seem to involve the condensing of a Dao Seal.

### World Force

Also known as the **Power of Heaven and Earth**, World Force is the strength of an entire Universe World. World Force is far more abstruse and powerful than the strength of World Principles, and consists of the combined power of the Yin-Yang + 5 Elements. Said to derive from a Universe World's Source, the World Force of these worlds can only be sensed and motivated by Great Emperors, as they have received the acknowledgement of their World’s Will (Heavenly Way).

Having successfully condensed and combined the strength of the Yin-Yang + 5 Elements, an Open Heaven Realm cultivator has formed their own Small Universe World within their body, which has its own Source, and correspondingly generates its own World Force. It is the strength of this World Force that gives the Human Race the capital to contend with the strength of the Monster Race, Divine Spirits, and the Ink Clan.

### World Barrier

Every Universe World has its own World Barrier. As long as a Universe World is sufficiently intact, a cultivator must at least reach the cultivation level of a Great Emperor (i.e. condense a Dao Seal) in order to readily break through its fetter and explore the Outer Universe.

### Limits

Universe Worlds typically cannot withstand the power of too many or too powerful Open Heaven Realm cultivators/Great Emperors fighting or residing within them. Low Rank Open Heaven Realm cultivators and above can seriously damage or even destroy a Universe World by doing so. However, the limits/background of Universe Worlds can be improved by certain methods. These most notably include the death of Low or Middle Rank Open Heaven Realm cultivators within a Universe World, and/or the blessings of a World Tree Subtree. This allows the Great Emperors of some Universe Worlds to use the power of Middle or High Rank Open Heaven, and also increases the amount of power their World can withstand.

In some Universe Worlds, the Heavenly Way is so strong that it allows cultivators to achieve Open Heaven Realm within them (i.e. Profound Abundant World).

### Refining Worlds

Open Heaven Realm cultivators can refine Universe Worlds to heal or even improve their own Small Universe. An Open Heaven Realm cultivator must make sure the Principles of the Universe World they refine match the Principles of their own Small Universe, otherwise it will damage their foundation. This method is **extremely taboo** in the Outer Universe, since trillions of lives occupy these Universe Worlds. Therefore, if it is done, it is usually done in secret or desperation when there is no fear of consequences.

### Dying Worlds

When a Universe World is dying, it may be sensed by Giant Spirit Gods. These peaceful peak existences of the Outer Universe will sit outside a dying Universe World until it has fully extinguished all signs of life, and then devour them as food.

### World Tree

All Universe Worlds have a corresponding fruit on the World Tree. When a World's Fruit is picked from the World Tree and consumed, its corresponding Universe World’s Heavenly Way and Background are heavily consumed and damaged. Universe Worlds all fall under the influence of the World Tree, which determines each one's Heavenly Way/Martial Dao.

## Small Universe

### High Rank Small Universe

At High Rank Open Heaven Realm, cultivators form a real and complete Universe World in their bodies. It can hold and grow millions to trillions of lives, and will remain after a cultivator's death. The Small Universe left behind by a dead 7th Rank is called a **Universe Paradise,** whereas the Universe left behind by an 8th Rank or above is called a **Universe Cave Heaven**. Generally, only 8th Rank Open Heaven Realm cultivators and above can confidently say their Universe Worlds are stable enough to safely store lives.

### Differences

The Small Universe of an Open Heaven Realm cultivator is part of the cultivator's body. Therefore, anything that affects their world will also affect the cultivator. Most of the same rules that apply to external Universe Worlds apply to these Small Universes with the following notable exceptions:

Unlike an external Universe World, High Rank Open Heaven Realm cultivators cannot afford to carelessly allow the Small Universes of other Open Heaven Realm cultivators to dissipate inside their own. The differing World Principles of their inner worlds can significantly and negatively affect the Small Universe of a cultivator. For this same reason, Open Heaven Realm cultivators do not allow other cultivators to promote to Open Heaven Realm while they are inside of their Small Universe.

Another exception is Great Emperor, as they do not appear to exist within Small Universe Worlds. However, there are similar situations in these worlds in which cultivators can motivate the World Force. Cultivators can also condense Dao Seals within a Small Universe if its Heavenly Way is strong enough.

### Dao Marks

The Small Universe Worlds of High Rank Open Heaven Realm cultivators, having a complete set of World Principles, carry Dao Marks representing each of the myriad Grand Daos for which a cultivator has a significant enough level of comprehension and attainments. Thus, Dao Marks strongly determine the overall World Principles of these worlds. This allows the cultivators that inhabit these Universe Worlds to gain higher sensibility toward these Grand Daos while within them. If one's own Grand Dao agrees heavily with a particular Dao Mark of a Small Universe, they are correspondingly able to far more easily gain further attainments on it. These cultivators can also far more easily draw upon the world's strength to enhance their usage of the particular Principles that correlate to this Dao. Grand Daos a cultivator has never browsed are not noticeable within their Small Universe as Dao Marks.

### World's Master

A similar existence to Great Emperor, a World's Master is one who has refined the Source of a Universe Cave Heaven or Paradise left behind by a deceased High Rank cultivator. The Source of a Universe Cave Heaven or Paradise is usually found in the form of a Palace or Structure that represents the center of the world. Likewise, the more one's own Grand Dao agrees with the main Dao Mark of a Universe Cave Heaven or Paradise, the easier it is for them to refine its Source. Once one becomes the World Master of a Universe Cave Heaven or Paradise, they can draw support from its World Force while controlling and sensing every part of the world. In other words, they enjoy the privileges the original cultivator enjoyed within their own world.

### Small Source World

Some High Rank Open Heaven Realm cultivators intentionally practice techniques like the Great Desolate Scriptures to make their Small Universe become a **Small Source World** after their death. This is a Small Universe where time moves much faster than the outside world, and is used by Cave Heavens and Paradises to quickly train disciples within a short period of time.
