Lu Xingzhi was unaware of the relationship between Mu Jiangyue and Yin Yu; he merely let slip unintentionally that Mu Jiangyue was his fiancée.
Upon hearing this, Yin Yu, filled with jealousy, had his pride to maintain, and immediately left in anger. Lu Xingzhi did not understand Yin Yu's reaction, but since Ling Tian Sect and the Sect Leader were already like fire and water, he didn't bother to ask more.
Late at night, Mu Jiangyue secretly met with Yin Yu, crying to him, saying that the engagement was not her choice; it was Lu Xingzhi who had threatened her with the lives of her entire family, forcing her to agree to marry him. The person she truly loved was Yin Yu, and only Yin Yu.
