The book, Medical Poison Concubine. If you like ancient romance novels, I recommend "The Phoenix's Power". It tells the story of the female protagonist who became an abandoned concubine after transmigrating, but she relied on her own talent to successfully counterattack and become the center of power in the Feng family. The story was full of ups and downs, and it was worth watching. I hope you like this fairy's recommendation. Muah ~π
