On the surface, it is a romantic story about a time-traveling female stand-in's counterattack, but it is actually a game between two powerful players with high IQ + a rule-based game. The heroine has the golden finger of "modern knowledge", but her biggest opponent - Shanghai warlord Shen Huaijin - has the ability of "cognitive tampering", which can rewrite anyone's memory of his words and deeds. In the game between the two of "True and False Shen Nianci", the heroine unexpectedly discovered that as long as she fully complied with the regulations of the "Code of Social Etiquette of the Republic of China", she could trigger the "logical completion" of the world's rules, thereby interfering with Shen Huaijin's "cognitive tampering" and even reversely rewriting his memory.
