The Concubine's Daughter Takes Charge

This is a story about transmigration.

Su Qi, a modern woman, transmigrates into the body of Su Pinlan, the illegitimate daughter of the Marquis of Pingnan, who died after accidentally consuming a large amount of aphrodisiac. Her reborn legitimate elder sister, Su Wenlan, has also lured her own dissolute husband from her past life, Pei Zuo, into the study and is preparing to have them caught in the act. That way, she can ruin Su Pinlan’s reputation, which she had envied because Su Pinlan’s life in her previous life was so happy, and also break off her engagement to Pei Zuo, the husband who killed her in her past life. Two birds with one stone.

After transmigrating, Su Pinlan realizes that someone has framed her and made her drink an aphrodisiac...
