Liu Zhiyuan, the daughter of an arms dealer, is transformed into the cannon fodder Liu Fei who is about to be executed by the tyrant in the book, and is bound to the file loading system in a desperate situation. However, every time she reverses course, she retains the memory of Xiao Yu, the tyrant who wants to kill her. From then on, she pretended to be good on the outside and wanted to survive, but complained crazily on the inside; he knew she was "casting a spell", but he couldn't kill her or escape, so he could only grit his teeth and cooperate. In the strange daily life of "she acts and he watches", the two go from deadlock to alliance, jointly investigating unsolved cases, outsmarting powerful officials, and quelling internal and external chaos. In the end, the tyrant dismissed the harem for her, and she listened behind the scenes for him. Together, they reversed the original tragedy and turned it into an eternal legend unique to them.
