Chen Mu is a "temporary worker" at St. Michael's Church - a priest in name. In fact, anyone in the town comes to see him if a house is haunted, if a child cries at night, or if the freezer in the supermarket next door opens by itself. The way he works is a bit wild: with his left hand he draws the Maoshan evil talisman, with his right hand he signs the holy cross, he chants the nine-character mantra, and he steps on the Yu steps. He had called the hotline in heaven, and there were 47 people in line. The call was answered 11% of the time, and he was often cut off midway. It wasn't until the Vatican sent two investigators - the blond Emily and the sister Lucy who always wakes up at critical moments - that Chen Mu discovered that this quiet town was not a small town at all. A hundred years ago, a certain priest secretly sold the "Fragments of St. Michael" to the world; once the seal was broken, strange things emerged from the ground. The living room of Harold's house, the innocent soul in the basement of the nunnery, Lucy trapped in the candle circle... Behind each "case" are the failures of the heaven system, the covetousness of the abyss, and the unfinished story of his grandfather Chen Daoxuan. Chen Mu just wants to be an exorcist in a small town. But the key, the door, and the "familiar smell" all pointed to the same person - himself.
