Protagonist: Lin Que, a 22-year-old recently graduated college student who is so poor that he accidentally activates the ancestral yin-yang eye + temporary labor system in the underworld. He works as a delivery person and catches ghosts part-time to earn money in exchange for his moral virtue. He is less courageous than a sesame seed and speaks faster than a firecracker. He relies on being mean, cheating, and being clever to catch ghosts.
System: A cheap temporary worker system in the underworld. It releases ghost-catching tasks and rewards Yin virtues (can be exchanged for cash, magic weapons, life-saving charms). If you fail, you will lose your life span, put up small advertisements for the underworld, and be harassed by imps. The main purpose is to deceive the host.
World view: There are all kinds of ghosts, evil ghosts, and spirits hidden in the underworld, including ferocious evil spirits, as well as strange ghosts such as social terror ghosts, job ghosts, lovelorn ghosts, road-crazed ghosts, and involuntarily ghosts. The underworld is poorly managed, and temporary workers are a mixed bag. Terrorist incidents are always resolved in a funny way.
