In ancient times, when chaos first emerged, Pangu transformed into all things, and his essence was scattered into three thousand worlds. The largest fragment among them is called Dahuang - the original world recorded in "The Classic of Mountains and Seas". In the wilderness, there are thousands of races, and mythical beasts are rampant. The human race, the demon race, the shaman race, and the god race live here together, each ruling one side.
Tens of thousands of years ago, the most powerful Human Emperor (descendant of the Xuanyuan family) and the most powerful Demon Emperor (bloodline of Zhulong) of the human race launched a world-destroying battle in the center of the wilderness. That battle shattered the wilderness and divided it into two: the Nine States Realm where the human race lived, and the Ten Thousand Demon Realm where the demon race lived. Between the two worlds, countless fragments were scattered in the void, turning into a small world of ruins with thin spiritual power.
