A youth from the Xu family of the Seven Great Houses, only thirteen years old. His real name is Xu Sa but Qian Lingyan nicknames him Xu Lifeng, which only Qian Lingyan is allowed to use. He cultivates wind-based Qi which grants him speed and agility. He is known for being unrestrained and blunt, weak when it comes to women, and impulsive. He jumped over the courtyard wall to invite Qian Lingyan out and later recklessly intervened when he saw Young Master Chen harassing Hua Rou.
