Chen Fei, 23, is a graduate of a sports university and a personal trainer. He has an incredible physique but terrible social skills. His girlfriend dumps him, saying, “All you know how to do is lift weights. Your brain is just muscle.” On the day they break up, a System appears. Its first mission: do 100 one-finger push-ups in front of everyone at the gym. The fitness System, called the Strongest Physique System, is a sharp-tongued wisecracker that assigns absurdly brutal tasks, but its rewards are outrageously generous.
