Recognize the Lord

Yun Lan, the head of the Yun family, has been reborn and vows to take revenge on all the traitors. She resolutely abandons the hypocritical "savior" Fu Chenghe and instead chooses Shen Zhiyan, the yandere boss of the underworld who committed suicide for love in her previous life. The two form a powerful alliance through testing and tug-of-war. Yun Lan sweeps away the internal enemies of the family, exposes the truth that her father and stepmother killed her biological mother, and regains all power. Meanwhile, she heals Shen Zhiyan's extremely love-starved heart, and Shen Zhiyan becomes her most solid backing with absolute loyalty and all his wealth. Finally, Yun Lan, who has avenged her great hatred, resolves her inner knot, conceives a new life with Shen Zhiyan, and transforms from mutually conquering opponents into lovers who reign side by side.
