Wei Xin traveled to a demon novel and became Wei Wuxian's sister inexplicably. She was confused. Then she went to Gusu to study and met Lan Yu. She was the master of the Demon Star Stone, the Demon Supreme, and Lan Yu was her Taoist companion. However, she was pampered by Wei Wuxian, Jiang Cheng, and the crowd. This felt good, hahaha, and there was Lan Yu who loved her. Hehehe.
