Lin Mo, a temporary worker in the underworld, spends his days saving ghosts, mediating neighborhood disputes, and dealing with weird KPIs. In order to become a regular employee, he developed the "Dream Year Card", "Ghost Emotion Management Course", and even launched a membership system for the underworld. The performance explosion attracted the King of Hell to interview him, but he unexpectedly took out his mobile phone and said: "I heard that VIPs can be reincarnated first? Give me a lifetime supremacy first." From then on, Lin Mo was forced to deal with absurd assessments and the officialdom of the underworld, redressing the cases of centuries-old souls, fighting against systemic corruption, and becoming a disruptor of the underworld's reforms from humble beginnings. This is a story about a little person using black humor and loneliness to tear open the cracks of warmth in the cold rules, and finally rewrite the rules.
