The World’s Greatest Backwater Martial Arts School

Jin Cheongun, commander of the Black Dragon Corps—a secret unit that answers directly to the Martial Alliance Leader—has finally left behind his long life in the martial world. Determined to carry on the legacy of the master he had spent his life avoiding, he returns to the countryside to open a martial arts school. But his ambitious retirement plan goes spectacularly wrong from the very start. “What? I was scammed?” First, he is swindled over his new home. Then martial artists begin pouring in. And as if that were not enough, students with complicated stories of their own keep appearing at his door. Thus begins Jin Cheongun’s chaotic life running a martial arts school.
