One gives rise to two, two to three, and three to all things. All things return to one.
Everything in the world begins with one, and must also end with one.
Thus, what is called chaos is the One and only.
Within chaos are countless worlds, and among them are five worlds known as the Five Forbidden Zones of Chaos.
[The Universe]
[The World of Fantasy Heavens]
[The Tree of Life]
[The Divine Origin]
[the Myriad Worlds]
Even beings of chaos dare not lightly set foot in these five worlds.
This story takes place in two of them: [The Universe] and [the Myriad Worlds].
For reasons no one knows, a fierce collision and conflict erupted between [the Myriad Worlds] and [The Universe].
A peak war involving both worlds broke out without warning, then ended just as abruptly. At the heart of the war was an Earth boy named Li Xingye.
The story of this boy, the representative of Earth, one of the four great celestial bodies of the universe, and a girl from one of the lower worlds among the Myriad Worlds, begins after the war ends.
