Xie Chen, a "chess player" in the underground world of City A, has been strategizing for ten years and has the entire city's interest chain at his fingertips. However, in a well-planned plot, he exchanged bodies with an eighteenth-tier gangster and was forced to travel back to his seventeen-year-old high school days. As an "old fox" with memories of the next twenty years and full of conspiracy and calculations in his heart, he calmly started his second life - sleeping in class, fighting after school, pretending to be an innocent boy. On the surface, he is an ordinary student enjoying his youth after rebirth. Secretly, he treats the school bully who bullied him into depression, sends the teacher who plotted against him to the police station, and uproots the rich second-generation family who suppressed him. Everyone thought Xie Chen was a loser who had been beaten back to his original form. Only he knew that he would always be the director of this youth drama. When the mastermind behind it finally surfaced, the scheming former boss decided to use a prosperous time to pretend to be innocent and make everyone pay the price.
