My Billion-Dollar Bride

The woman Wang Wuji came down the mountain for was part of a setup, and he lost a kidney to it. He had trained alone at Shushan for years before the online romance pulled him into the world below. He sets out to get the kidney back, one short in the meantime. In the middle of that he saves Ren Yuening, whose father is a magnate. She settles on him almost at once and marries him fast, with a dowry of ten billion attached. The two of them go on to an engagement banquet where several masters are present and intend to make him look small in front of the room. He answers by using the sword work Shushan trained into him, with everyone at the banquet watching.
