Yes, I recommend "That Man in the Pugilistic World". The male protagonist, Gu Qingci, traveled to a world where the pugilistic world and the imperial court were on par. He had a chivalrous system and had read all kinds of pugilistic world chivalrous men. He quietly entered this strange pugilistic world and lived in the imperial court. He loved his children and sang heroic songs. It also involved the storyline of Little Li Flying Dagger. I hope you like this fairy's recommendation. Muah ~😗
