There is! I recommend two novels,"The Counterattack of Daiyu" and "The First Killer: The Heaven-Defying Sick Concubine", to you. Both of them are female protagonists who have transmigrated into a sick person with a strong heart and strong cultivation. The two novels are about ancient romance and time-travel fantasy. You can choose the genre you like. I hope you like my recommendation, Mwah ~😗
