Her identity is unknown, and she is referred to as "Little Ancestor" by the man in black. She was known as one of the Four Beauties of the Lingxi Sect, but this is a false identity. During her time at the Xuexi Sect, she possessed Du Xuemei's body and acted using hers. Initially, she disliked Bai Xiaochun's cowardly nature, but was later moved by his selfless act of saving her and his companions, developing feelings for him and falling in love with him.
