In the sinister world, Yue Qingyu, the elder brother of the Yueshan sect, fell in love with Yao Feiyan, the daughter of Yaojian, the leader of the Yaoshan sect. The two were about to get married, but the disappearance of a jade stone caused the two sects to turn against each other, and their marriage was cut off. A few years later, Yue Qingyu's master married Yue Qingyu and his friend You Fangzhi's daughter, You Mingxue. They were engaged, but there was still an unsolvable knot in Yue Qingyu's heart like Yao Feiyan.
