Su Wan, a top appraiser who died tragically in his previous life, became the temporary judge for the underworld's illegal work. Her KPI is to identify the object of obsession of the deceased soul, and she earns virtue to exchange for a place for rebirth. Using the "undead cell phone", she secretly planned revenge in the underworld, but attracted the cross-border attention of the paranoid boss Lu Jin. He robbed her and wanted to use her for his own purposes; she sneered and dealt with her, using his power to liquidate all her enemies. When the quota for rebirth and the establishment of the underworld were placed in front of him at the same time, Su Wan showed his job badge to Lu Jin who was chasing after him like crazy: "Sorry, Mr. Lu, I choose to become a full-time official." - Chief Judge of the Underworld, specializing in dealing with dissatisfaction in the upper world.
