Gu Yunxi is a beautiful young woman living alone in a suburban villa. She first encounters Ji Chuan when he breaks into her backyard and steals her pink car. Initially terrified, she later realizes he means her no harm and brings her food supplies. She has a golden crystal core and her special ability is "adjustment": she can amplify or reduce the power of other people's abilities. This makes her a valuable ally. She forms a close bond with Ji Chuan and Lin Lulu, offering her home as a base. She is kind, emotional, and grateful for Ji Chuan's help, and she supports his revenge plan.
