Universe Furnace

Known for its containing of the Universe’s spontaneously produced **Open Heaven Pills**, the legendary **Universe Furnace** is actually a Small World that is said to be both a great chance and a great disaster each time it has appeared within the 3,000 Worlds. This is of course because the Open Heaven Pills found within the Universe Furnace are widely known to ignore the shackles of Open Heaven Realm promotion. As it provides the miraculous hope of attaining a higher Martial Dao to those at their road’s end, the appearance of the Universe Furnace has caused the deaths of countless competing Open Heaven Realm cultivators over the course of its history.

Eventually, it is discovered by Yang Kai that the true body of the Universe Furnace resides within **Chaos**, and that the Furnace itself is the birth place of the 3,000 Worlds, an untold number of other worlds like it, Celestial Phenomena, and all Universe Worlds.

## Opening

### Entrance

As seen in the 3,000 Worlds War against the Ink Clan, the Universe Furnace's opening starts with the appearance of giant illusory replicas of the Universe Furnace in areas where there has been a significant amount of violent deaths. Eventually, an indeterminate amount of these illusory replicas will congeal into reality, allowing cultivators to enter the Small World of the Universe Furnace.

### Evolutions

According to Blood Crow, the Universe Furnace undergoes 9 evolutions before it closes again, and each evolution is marked by the rearrangement of the Small World's shattered Dao Marks. Therefore, the environment of the Universe Furnace changes somewhat with each evolution as its shattered Dao Marks get more and more perfect. Eventually, the Dao Marks become completely ordered after the 9th cycle. After the 9th evolution, the Universe Furnace will close, and all participants are returned to the place where they entered its Small World.

Because martial artists rely on the Dao Marks of the world to use the strength of their Grand Daos, Human Race cultivators are weakened in this aspect during the early evolutions of the Universe Furnace, forcing them to mainly rely on the strength of their flesh bodies and/or their World Force.

## Chaos Spirit Race

A unique race of beings that are spawned from the shattered Dao Marks of the Universe Furnace, the Chaos Spirit Race start as a Chaos Body that can consume either lower or Best Quality Open Heaven Pills to take the shape of many different creatures, including the Human Race, becoming Chaos Spirits that are equivalent to different ranks of Open Heaven Realm in strength. Likewise, a Chaos Spirit that has consumed a Best Quality Open Heaven Pill becomes a 9th Rank-equivalent **Chaos Spirit King**. Though generally peaceful if unprovoked, Chaos Spirits will congregate and relentlessly attack anyone in the furnace who either attacks them first or targets an Open Heaven Pill they are in pursuit of.

## Open Heaven Pills

### Grades

* Best Quality Open Heaven Pills - Numbering only 9, it takes just one Best Quality Open Heaven Pill to complete a martial artist’s Grand Daos, allowing them to directly promote one rank regardless of their limit. Not only useful for the Human Race, Best Quality Open Heaven Pills have been shown to also work for the Ink Clan and the Chaos Spirit Race.

* Lower Quality Open Heaven Pills - Like the pills Yang Kai found in the Blood Monster Cave Heaven, Lower Quality Open Heaven Pills are only useful in helping Open Heaven Realm cultivators to overcome bottlenecks.

**Exception**: Because Best Quality Open Heaven Pills help cultivators to break through their limits by completing their inherently incomplete Grand Daos, Yang Kai's altering of his overall Grand Daos through his practice of the **Three Parts Reunification Art** has made even Best Quality Open Heaven Pills useless in this regard. Therefore, Yang Kai determines that his only means to achieve 9th Rank Open Heaven Realm is through the practice of the Three Parts Reunification Art with Ying Bao and Fang Tian Ci.

## Endless River

Far more potent than the Celestial Rivers Yang Kai entered on Ink Battlefield, the Endless River of the Universe Furnace carries both the extremely pure Yin-Yang + 5 Element Grand Daos and all of the myriad Grand Daos that stem from them. Likewise, it is the Endless River of the Universe Furnace that has allowed it to create the myriad heavens in existence.

### Celestial Phenomena

After traveling to the never-before-seen parts of the Endless River due in large part to his unprecedented attainments in the myriad Grand Daos, Yang Kai discovers that the extremely pure myriad Grand Daos have seemingly given birth to extraordinarily powerful creations. Feeling like a speck of dust in front of these immensely powerful existences, the Peak 8th Rank Open Heaven Realm Yang Kai then recognizes them as Celestial Phenomena.

### Expanding World

As stated earlier, the Universe Furnace resides within Chaos as it performs a constant cycle of absorbing a large amount of the surrounding Chaos, converting it into the power of the myriad Grand Daos, and then expanding and creating the 3,000 Worlds, and an untold number of other worlds like it, through the power of its Endless River. As such, it is figured by Yang Kai that the Universe Furnace may continue this cycle until Chaos no longer exists, and all of existence will have a finite end.
