Lin Sasa, who lives in the demon clan day and night, was accidentally hunted down and fled to Taixu Sect where she met Gu Shiyan, the leader of the sect who was worshiped by everyone.
Lin Sa Sa couldn't stand the way he was more pushy than her and decided to "visit (teach)" the other party in the evening, but was beaten by the other party. Lin Sa Sa vowed to defeat him after repeated defeats.
Just after beating her, Lin Sa Sa discovered that he suddenly changed his gender. Not only did he stop beating her, but he also gave her various treasures. He was not even angry when she threw his natal sword into the trash. Lin Sa Sa couldn't sit still.
