After pulling an all-nighter to revise a proposal, overworked office drone Jian Qing casually opens a mystery novel. His vision goes dark, and when he opens his eyes again, he's lying on the cold metal table in a morgue. He's become a young police officer who was just murdered in Wuzhen, and the original owner's resentment is slowly eating away at his consciousness. The town is shrouded in eerie white fog all year round. Over the past thirty years, thirty-seven people have vanished, and every local ghost story has become a deadly reality. He has just one month: if he can't solve the string of disappearances, he'll lose himself completely. At the brink of despair, his Demon-Slaying System activates. He can earn spirit points by completing investigations, then trade them for talismans and spirit detectors. From a helpless rookie, he fights back against evil spirits and face-slaps the cultists, one step at a time. But the closer he gets to the truth, the more horrifying things become: the town council has been infiltrated by the Mist Cult, a century-old seal is beginning to weaken, and even he can't tell how many secrets this body is hiding. On the night of the full moon, the sacrificial ritual is about to begin. Can he unmask the culprit at the last moment and protect Wuzhen?
