In 2099, after the "Dust Collapse", the world became a wasteland, resources were exhausted, and order collapsed. The surviving humans huddled in the fortress city, divided into the powerful in the upper city and the ants in the lower city. The protagonist Qin Lie is the most ferocious "underground boxer" in Xiacheng District. In order to repay the huge debt for his dead sister, he fights for his life in the bloody boxing ring every day.
The sudden mutation frenzy broke through the barrier. Without any golden fingers and no system, Qin Lie relied only on the terrifying killing skills honed in the black boxing world, extraordinary fighting intuition and extreme tolerance for pain, and led the female protagonist who is a war reporter to break out of the siege. He established power in the wasteland, fought against mutated creatures, plundered resources, and uncovered the truth about the apocalypse. In the end, he used his mortal body to defeat the genetically modified warriors and mecha legions, and reshape the new human order.
