According to the information provided, I recommend the ancient romance novel "The Godly Doctor's Seven Concubines" to you. Although it did not completely match the description of the father and daughter, the female protagonist was reborn as a forensic genius and returned to the ancient palace to become the concubine of the Seventh Prince. And the Seventh Prince's mother was wronged by a traitor and was grounded in the palace. The Seventh Prince was poisoned and needed the help of the female lead to remove it. Although the relationship between the female protagonist and the Seventh Prince was not father and daughter, it would definitely be exciting. I hope you like this fairy's recommendation. Muah ~😗
