Fei Nü Yao Shen

The great demoness Bai Youling lost control of her powers on her wedding day, and had to be put down by her lover with a sword through her heart. She found herself reborn into the body of the spoiled daughter of the Bai family. Now she'll fight back against those who betrayed her, as she tries to regain her cultivated powers, even if she has to become a disciple of her former lover. Just wait, all you fake do-gooders. "Especially you, Xu Xiyuan, as I will make you feel what it's like to die by your lover's hand!" (Source: Tencent, translated)
