After I Was Released from Prison, I Traveled Across China

[Underworld + business war + no system + no brainlessness + reality + reaching the peak] Eight years in prison allowed a former gang member to re-understand the world through reading. When he was released from prison, the original boss failed to fulfill his original promise. He was just assigned to a branch of a gang that had declined. And he chose to wander in the gray area on the edge of black and white. In the process, he encountered betrayal from someone close to him, blocked a joint attack by his colleagues, broke through the suppression of money ability by business bosses, and escaped the police's relentless investigation and evidence collection. Eventually he became the hidden boss who controlled the entire China.
