At eighteen, Lu Zheng is struggling to survive by repairing cars and taking odd jobs. His mother is gravely ill, his father has disappeared, and then a gang of school bullies steals the money he needs to save her and humiliates him by stomping him into the mud.
The day he can take no more, the [Punish Evil Combat System] activates. The crimes, weaknesses, and openings of evil people become impossible for him to miss.
School bullies, campus tyrants, student-loan sharks, underground fight-ring bosses, and finally the black-money empire that has controlled Dongjiang for years: he fights his way up, one punch at a time, to reclaim the blood debt.
The System doesn't make him invincible. When he challenges stronger opponents, his bones crack, he spits blood, and he falls. But he doesn't back down, kill indiscriminately, or hurt the innocent. He's never wanted to become a new villain. He wants every villain to pay back what they owe, with interest.
From a boy pinned down in a corner to the reckoner who topples Dongjiang's entire criminal network: when evil people begin to fear, ordinary people can finally hold their heads high.
