At the end of the wedding, after Su Yuan officially acquired the Jiang family's property, his fangs finally revealed themselves. He killed his "wife" Jiang Yunyan, who had been acting for many years. Before her death, Jiang Yunyan also learned the whole truth, and she was reborn with anger and despair. After her rebirth, she returned to the time when she first formally met Bai Muchen, which was a month before the wedding. Jiang Yunyan knew that it was difficult for her to bring down Su Yuan on her own, so she took advantage of Bai Muchen's moment of distraction and directly had Bai Muchen come to propose on the day of the wedding.
