Beginning of Return to the Ruins

The name "Guixu" comes from "Liezi·Tang Wen" - "East of the Bohai Sea, hundreds of millions of miles away, there is a big ravine. It is actually a bottomless valley with no bottom below it, so it is called Guixu." Guixu is the ultimate valley where all waters return and all phenomena are hidden. After three catastrophes of heaven and earth, the layered caves, scattered secret realms, and gods, Buddhas, immortals and monsters all left the human world and returned to the ultimate abyss, finding their respective "returns" - the eternal silence and balance. The moment when thousands of planes are separated from the human world and the immortal world is separated forever is the starting point of this epic.
