Mo Lin was appointed as a Yin official in Ye Dou and returned to Earth carrying the Book of Ghost Suppression.

The Earth has been taken over by evil spirits.

"Brother, don't go out at night. There are ghosts and monsters outside. It's too scary."

"Ghosts? Sorry, I'm not afraid. The more ghosts and monsters there are, the more excited I get."

"This guy is full of ghostly energy, at least a demonic level. Watch me catch him." The righteous old man took an unknown talisman and stuck it on Mo Lin's head.

"Are you crazy? You're the ghost, your whole family are ghosts!" Mo Lin tore off the talisman and cursed at the old man.

The old man was left standing alone in the wind, bewildered. "This ghost is too fierce; it's not even afraid of talismans."

...

Mo Lin returned to Earth and began his ghost-hunting journey... Ten years later, Mo Lin led a hundred ghosts through a certain street, earning him the reputation of the strongest ghost hunter.
