Cui Jue, the chief magistrate of the underworld, transformed into Cui Wan, a single mother who was a temporary kindergarten worker and was heavily in debt due to a system bug. Faced with the pressure of her daughter's sky-high school district housing and the magical power sealed in the world, she only has a pair of judge's eyes that can see through the "karma and consequences" of all things. As a result, the most hard-core chicken baby plan in history was released: use the logic of the book of life and death in the kindergarten to mediate children's toy disputes during the day, and transform into a "haunted house purifier" at night to accurately locate ancient tombs that have excessive resentment and affect the balance of yin and yang, and "sell" the information to the archaeological team in exchange for rewards. Since then, a legend about accurately "picking up leaks" with children has circulated in the cultural relics world. Parents are hotly discussing this gentle teacher who suddenly cheated. In the underworld work group, Judge Cui's work report has become: "A feasibility statement on the feasibility of working part-time in the human world to earn childcare funds while maintaining the balance of yin and yang."
