He is an illiterate gangster who is disliked by everyone in the urban-rural fringe area. He lives in the shadow of his father's sighs, his mother's tears and his brother in prison. Until he mistakenly entered the "Moxiang Pavilion" and was pushed in front of the stack of books by the shop owner Mo Zhixiu: "From today on, your life will reset to zero." Moving books, arranging books, drawing calligraphy, reciting... A cruel and sophisticated "points" system, grinding his rough fists into cocoons for holding pens. When the dormant talent of "photographic memory" suddenly awakened, a centuries-old family bet was restarted: to retreat into an underground book tower for three years, with a hundred thousand unique books as companions, in exchange for a complete nirvana. When he comes out of seclusion, he will no longer be Wu Niu. The solid foundation of knowledge will eventually support a new soul named "Wu Jiahao" to illuminate his own path in the world.
