Scheming Alongside the Legitimate Daughter

In her previous life, Gu Qingwan was framed by the fake heiress adopted by her mother and died with hatred in her heart. Reborn, Gu Qingwan encounters the tyrant who will one day kill her entire family. To protect her family, she makes the poisoned tyrant's condition even worse, smearing the most toxic poison on his wounds. But, unexpectedly, poison counteracts poison, and she becomes the benefactor in the tyrant's eyes. When the tyrant is beaten within an inch of his life, she wants to go finish him off. But he suddenly wakes, thinking she risked her life to save him, and even begins to regard her as the light of his heart. What she least expects is that, once the tyrant's power has grown and he has become a regional overlord, he will return in earnest to "repay her kindness."
