Ancient Line: Reinterpret the stories of Li Jing, Hong Fu and Qiu Beard Gong. In Wang Xiaobo's writing, Li Jing is not only a military strategist, but also a great mathematician (even proving Fermat's theorem). The novel depicts Li Jing's transformation from a "rogue intellectual" (free, interesting) in Luoyang City to a "Guoguo Gong" (in the system, boring, pretending to be stupid) in Chang'an City.
Modern Line: It tells the life of the modern mathematician "Wang Er". In order to become a "renrui" (a model recognized by the system), he worked hard to prove Fermat's theorem, but in the end he fell into identity alienation and mental dilemma.
