The World’s Greatest Martial Arts Instructor

The Demonic Cult Leader, Seok Woncho, was a monster who even surpassed the Blood Cult Leader.Do you know who killed him? “Ha Mu-baek.” “But why are you bringing that up…?” “Because he’s coming to our Mengryong Academy as an instructor.” …Damn it. We’re screwed! Ha Mu-baek, the greatest martial artist who crushed both the Demonic Cult and the Blood Cult, is now assigned as an instructor at a martial arts training academy due to a political power struggle. Determined to live quietly while keeping his identity hidden, he soon finds himself solving the problems of cadets with heart-wrenching backstories, disciplining the trashy human scum at the academy, and inexplicably becoming busier by the day… Welcome! It’s your first time meeting a genius lunatic instructor, isn’t it?!
