Under the shadow of modern cities, there lies the unknown world of alchemists. Ancient sorcery, dead ghosts, corpses refined by taboos... Are still quietly growing in the cracks of the reinforced concrete jungle.
Wen Kai, a young folklore affairs handler, seems to be running an inconspicuous Guyun Pavilion lazily, but in fact he is responsible for a nearly lost family skill.
The only complete inheritance in his hand is a dilapidated and illegible "Secret Record of Suppressing Evils" - it is said to be a record of the ancestors' experiences in descending corpses and collecting ghosts. However, due to the long history and wars, only half of the volume remains. Many key spells and rituals are missing, and it is even mixed with the scrawled annotations and speculations of the ancestors.
He managed to maintain his ancestral business by relying on this half of a broken book of music, his keen intuition about folk dirty things, and his daily solution to common numerology and feng shui problems:
Dealing with unclean things for people - as small as home feng shui, calming evil spirits in the house, sending away wandering spirits, as big as sealing evil corpses and breaking evil spells.
He must uncover the terrible truth behind the evil object and prevent the disaster from spreading. At the same time, through dangerous experiences, he tries to complete the missing chapters of the "Secret Record of Suppressing Evil" and retrieve the truth about the interruption of the family inheritance.
