Xu Lang is Jinling City’s number-one “cad,” dating eight women at once and known as the “Little White Dragon of the Waves.” He knows exactly what he wants: making money is fine, but getting involved in romance is not. He’ll never take responsibility for any woman, not in this lifetime. Then one day, Gu Changfeng, the son of a warlord, shows up at his door with a marriage contract and a squad of armed soldiers, demanding to break the engagement in public and humiliate the Xu family. Xu Lang glances down at the marriage contract, then looks up at Gu Changfeng’s arrogant face and bursts out laughing. Breaking off the engagement? Sure. But he pulls another piece of paper from his clothes: a marriage contract personally promised by the old master of the Gu family years ago. It clearly states that the two families are to be joined in marriage, and if the Gu family backs out, they must pay half an iron mine as compensation. What’s more, Gu Qingyao, the Gu family’s legitimate daughter, must marry into the Xu family. The crowd erupts. Gu Changfeng turns green. He came to break off an engagement and ended up giving away his most precious older sister. What he never expected was that Xu Lang, the “cad,” would set his sights on him next. Xu Lang has bound himself to the Unconventional Choice System, whose rewards get crazier the wilder his ideas. He takes Gu Changfeng’s mine, poaches his people, steals his weapons, and finally even snatches his father’s position as warlord. Years later, Gu Changfeng kneels atop the walls of Jinling City, watching Xu Lang sit in his marshal’s chair, with his sister in his arms and his military seal in hand. He cries out in despair, “Xu Lang! What do you even want?!” Xu Lang blows out a ring of smoke and smiles. “Your sister’s pretty.”
