Five years ago, Gu Yanzhi and his stepsister Su Lianyue conspired to frame Su Qingwan, leading to the execution of the entire Su family. The legitimate daughter Su Qingwan fell into the cold Han River, and everyone presumed her dead without a trace. Five years later, the mysterious divine doctor and legitimate daughter Yun Su returns to the capital with her twin treasures, exposing poisons and hidden secrets, turning the Marquis's estate upside down. She is the orphan of the Su family who masters the Wanyun Pavilion, returning with hatred solely to wash away her grievances and exact revenge for the Su family. Prince Jing Xiao Jue recognizes her as his savior from five years ago, acting as a shield to protect her and their children as they jointly overturn the treasonous web at court. The twin treasures and the legitimate daughter's comeback, featuring the divine doctor punishing scumbags and Prince Jing pursuing and protecting his wife, work together to clear the old case of the Su family and vindicate the legitimate doctor under the influence of the Wanyun Pavilion.
