The protagonist, Li Xiaotian, was once a notorious underworld boss who ruled his territory, but he died at a carefully orchestrated “Hongmen Banquet” after being betrayed by one of his brothers. Reborn in the year 2000, he finds himself back when he was just a small-time punk entering the underworld. He binds himself to a comical “God-Tier Underworld System.” Its missions are often useless or downright ridiculous, but completing them brings incredibly powerful rewards. He vows to rise again, reclaim the territory that was his, and completely reshape the underworld.
