There are a few novels that meet your requirements! For example, in "My Student Can Change History," the main characters were teachers of famous historical figures, and their martial arts were also very strong. There was also "The All-rounded Teacher." The protagonist could teach you all kinds of martial arts, battle energy, magic, and so on, making you an all-rounded existence. There was also "The System invites me to be a teacher". The main character was a teacher in a parallel dimension. Although he was an ordinary person, he had various skills and specialties that made him the strongest teacher in history! I hope you like this fairy's recommendation. Muah ~😗
