Our protagonist, Chen Mo, is an ordinary young man who opened a folk shop. He accidentally discovered a dark ancient account book and an animal head scale hidden in his attic. This thing is very evil - whenever someone in the city is entangled by evil spirits or spirits, that person's name and "pawn" will automatically appear on the ledger. Chen Mo can use this to come to the door and use the method of "pawn" to take away the evil spirits attached to the person. And these "evil spirits" he collected ultimately point to a huge conspiracy to subvert the city.
