After Li Feng, a state-owned enterprise employee, died of overwork, he was reborn and returned to his first day on the job. This state-owned enterprise looks ordinary on the surface, but in fact it is a secret agency that houses "weird" people. In his previous life, he was PUAed to death by his boss Wang Hao. In this life, he decided to completely destroy him. Faced with the urgent "containment task" thrown by Wang Hao, Li Feng no longer stayed up all night, but strictly followed the company's most cumbersome and oldest rules. Every one of his fishy behaviors - such as applying to use the sealed materials in the deepest part of the warehouse in order to delay time, or rigidly implementing the old rule of "isolate first and report later" in order to get off work on time - were interpreted in Wang Hao's eyes as an unfathomable political game. Wang Hao imagined that Li Feng had Tongtian's background and was taking the opportunity to beat himself up. However, none of them knew that the "old rules" that Li Feng inadvertently implemented were precisely the most effective sealing ritual to deal with the "weird resurgence". So, when everyone thought the doomsday was coming, only Li Feng's work station barrier was impregnable, and he himself was watching videos leisurely with headphones on.
