Chen Xing, a seemingly ordinary night shift clerk at a convenience store, is actually ruthless and decisive, but he is as gentle as water to the adorable three-year-old baby "Tangtang" in his arms. One day, he accidentally bound to a "strongest daddy system" that was full of loopholes. This system not only has confusing logic in issuing tasks, but also has inconsistent rewards. It even often teleports Chen Xing to strange places. However, it was these system bugs that allowed Chen Xing to get acquainted with various hidden masters in the city: the security uncle who was like a sweeper, the ace killer who sold vegetables, and the former king of soldiers who drove a rental car. Chen Xing took advantage of the loopholes in the system and led Tangtang to push him all the way among the experts. He not only wanted to protect his children, but also uncovered the mystery of his life experience. This is a story that coexists with passion and warmth. See how the ruthless Chen Xing makes mistakes for the sake of a cute baby, turns bugs into artifacts, and becomes a legend in the midst of laughter.
