The protagonist, Gu Qingshan, is the boss of the county town's "One-stop Service". He has followed his grandfather to do dirty work since he was a child and has seen dirty things. When the world first discovered the resurgence of supernatural beings, he had already been working in this industry for twenty years - so what others saw as horror films was familiar to him: bargaining with ghosts, settling accounts, and sending them away, which were both scary and funny, with a touch of human touch. His "golden finger" is not a system, but the "Miscellaneous Records of White Matters" passed down by his grandfather and a set of rules of "humans and ghosts".
