He was originally a demon hunter with yin and yang eyes, but he lost his original eyes because of his yin and yang eyes.
Later, he accidentally came to a cave, and when he exited the other entrance of the cave, he entered a completely different world than before.
He paused there for a long time, and finally decided that he couldn't go back.
There is no other exit in this cave.
So he went down the mountain, met Chu Liuxiang, and then saw the erotic ghost behind Shi Guanyin.
So he killed the erotic ghost.
... So, he wore it again.
