Security captain Chen Lie was humiliated by having his spine broken in public. Five years later, he returned to the underground boxing ring as the Hell Fighter. The stronger the pain, the crazier his strength. When he tore apart the bloody curtain in the arena, he discovered that the champion Su Wan was actually related to the gangster of the year; the lame steward Zhao Laizi hid a chip that could detonate the entire power network, and the body of the painless young man Ah Qi was quietly nurturing the ultimate power that could devour everything. When the Obsidian Society's hounds surrounded him, Chen Lie finally understood: the real torture is not physical destruction, but tearing apart the person you trust most with your own hands.
