Devil's Part-Time Job Manual

On the first day Lin Ye moved into the haunted house, three ghosts made a plan for him: scare him to death. The plan failed. It's not that the ghost doesn't work hard enough - it's Lin Ye who is born unable to sense supernatural phenomena. The ghost bared its teeth and claws in front of him, and he just felt that the air conditioner was broken. Then things changed. The Hanged Ghost became his roommate, the Drowned Ghost helped him cook, and the Knocking Ghost opened the door for him every day. They changed from "taking your life" to "working for you", and from being a life-demanding ghost to a shared nanny. What's more terrible is that the world is changing - humans are gradually losing the ability to fear, ghosts have become endangered species, and the underworld has issued a "Manual on Gentle and Scary Matters", requiring ghosts to scare people in a civilized and standardized manner. Lin Ye felt that he was just an ordinary social animal. But in the eyes of all ghosts and ghosts, he is the "Patient Zero" who has made humans fearless. And he just wanted to ask: Who will wash the dishes today?
