On QQ, the novel "The Reborn Female Guard of the Abandoned Prince" met the requirements. In the book, the male protagonist's surname was Gu, and the female protagonist's original name was Bai Zixing. After her rebirth, she changed her surname to Yin. I recommend this book. I believe you will like the story of this reborn female guard. She used her martial arts and wisdom to become a king, displaying the strength and wisdom of women. I hope you like this fairy's recommendation. Muah ~😗
