Marriage Swap of the Immortals

Qing Yang was about to be elevated to high immortal when her younger sister Qing Yue, eaten up with envy, pushed her into the Immortal Cleansing Pool and she died. She comes back on the day of the celestial marriage selection. Qing Yue remembers the future too, and takes the red thread that was meant to bind Qing Yang to Xie Wuxia, a rich and prominent match, and claims the betrothal for herself. Qing Yang lets it go. She knows what Xie Wuxia is like underneath. She marries Chang Heng instead, a nameless wild demon her whole clan looks down on, and takes the public humiliation that comes with it. At the wedding Chang Heng arrives alone with nothing, and then a high immortal kneels to him. She goes back to the Qing Bird clan for the customary visit and they trample on her. Qing Yue passes off the gifts sent by the Emperor as her own, and Qing Dashan orders Qing Yang to kneel and cut ties with the family. Chang Heng reaches the house in time. A true dragon comes out with him.
