After Lin Fan died suddenly and entered the underworld, he actually became a civil servant in the underworld by relying on the SWOT analysis method he had learned at the street office. Holding the [Urban Management] [Plaints and Calls Office] ID card in hand, he used red-headed documents to clear the way, reduce administrative penalties and attack, and managed the evil spirits to be submissive. From midnight buses to ghost school bullying, from human experiments in ghost hospitals to sweat and sweat obsession in black factories, he gradually uncovers the truth about his sudden death - at the same time, the secret of heaven, the awakening of evil gods, and the grudges of his past life three hundred years ago are pushing him to an ultimate choice that affects the survival of the Yin and Yang worlds. When the rules themselves became oppression, he decided to include evil gods into the system.
