Qu Yunfan has known since he can remember that there is a ghost behind everyone, and ghosts hide in the shadows. Most ghosts are relatively friendly and will play some harmless "games", but some ghosts are very dangerous. They can "eat people", turn people into monsters, and do unreasonable things. Of course, if there is an unclean party, there will also be a good party. Someone will deal with them. He is just an ordinary person and cannot be a saint. By the way, is he a ghost? Yes, but he can't see his own ghosts, he can only see other people's ghosts.
Purpose: Everyone has ghosts in their hearts, but don't be swallowed up by them.
