Yao Xianzi, also called Maid Yao, is a beautiful woman in green clothes with a blue sash. She was sealed within the Ghost Tomb Space 700 years ago after a cataclysmic battle, along with three other masters. She has a fiery temper and values her chastity greatly. When Jiliu Jia jokingly asks her to be his wife, she attacks him in anger. She is one of the four sealed masters who await Jiliu Jia's Ghost Tomb Body to help them break the seal. Despite her cold exterior, she is said to have a warm heart. She appears from the water in the valley where Jiliu Jia lands after falling off a cliff.
