He was once the proud son of Huahai City No. 1 Middle School. His grades were among the best, and Tsinghua University and Peking University were within reach. In his senior year of high school, in order to save his classmate Li Jiaqi who was entangled by gangsters, Xuan Yi accidentally killed someone while pushing him and was sentenced to three years in prison for intentional injury.
Everyone thought his life was ruined, but they didn't know that the three years in prison were an alternative "university" given to him by fate.
In prison, he learned killing and fighting skills from the descendants of the old Northeast Anti-Japanese League members. He also learned mind-reading and business management from the former chief engineer of a state-owned enterprise who was imprisoned for economic crimes. He also rescued the Northeastern Tiger "Master Tiger", a gangster who was being hunted by the underworld and was hiding in prison.
