Mu Jing, a passionate and unrestrained patient with late-stage syndrome, was accidentally bound to the "Confession Assistance System". In order to confess to the senior sister he has a crush on, he must complete the history rewriting task issued by the system - to create a "spoof confession scene" at each dynasty node. From holding banners on the scene of burning books and humiliating Confucians in the Qin Dynasty, to dancing at the Zhenguan Banquet in the Tang Dynasty, to including love letters in the Yongle Ceremony of the Ming Dynasty. He thought he was joking, but he didn't know that every absurd move was correcting historical bugs. Until he discovered that the senior's true identity was actually the inspector of the History Administration, and that behind his system mission was a conspiracy related to the survival of time and space.
