The Sky Is Missing and Strange Things Are Happening

Thousands of years ago, heaven was crazy, reincarnation was incomplete, and ghosts existed. Someone cured the way of heaven, but the reincarnation was not completed, and the ghost was temporarily hidden. Thousands of years later, reincarnation has become more broken, and ghosts are back again, and there are more of them. Someone snatched reincarnation and the ghost completely disappeared, but he himself was trapped in the endless void and could no longer find his way home.
