I recommend "My Favorite Concubine: Your Majesty, Take It Easy", an ancient romance novel. The female protagonist was once the daughter of a general and was well versed in martial arts. After her entire family was killed, she disguised herself as a man and rode on a horse with a knife just to find out the truth. She met the prince who had returned to court as a hostage, and their relationship gradually deepened. The male protagonist was sick and had been given a jade pendant by the emperor, which was related to the succession of the throne. In addition, the male protagonist's father also had an aunt who pretended to be crazy. I hope you like this fairy's recommendation. Muah ~😗
