[Invincible + Urban + Feel-Good Read + Revenge + Conquest + Ruthless + Clever Protagonist]

To find his younger sister, who was kidnapped years ago, Xing Fei leaves home and heads to Nu City, a place near the border in a lawless zone outside anyone's control.

Known as the City of Sin, it lies beyond the reach of the law. The major gangs fight and scheme against one another, and violent incidents erupt every day.

Soon after arriving, Xing Fei is accidentally drawn into a power struggle between three factions. Power, wealth, and beautiful women come with both danger and opportunity. He maneuvers between the factions, turns the tide, and takes over Nu City, becoming a legendary crime lord.
