In the modern cyberpunk city "New Luo City", underground boxer Lin Feng accidentally obtained the "cyber ancient martial arts synthesis system", which can combine mechanical parts with ancient martial arts moves (such as mechanical arm + Wing Chun = "Mechanical Wing Chun·Inch Power Cannon"). He started in the underground boxing ring, blasted his mechanical opponents, fought against the "Xinluo Technology" consortium that controlled the boxing ring, and rescued the transformed mechanical female agent Su Wanqing. In the process, Lin Feng unlocked the levels of "Iron Bone-Silver Heart-Golden Soul-Holy Body", gradually exposed the consortium's conspiracy to replace humans with mechanical bodies, and eventually became a "Cyber Martial Saint" to protect the city and achieve reconciliation between humans and machines.
