Iltagangsa Baeksabu

Once the finest instructor in the Blood Cult, Suryong Baek is killed, only to wake up in the body of someone who teaches martial arts at a small rural academy. His new body may be weak, but he knows how to fix it, and it’s not the first time that he’s found himself in a body that can’t access its inner power. Curing his body requires money, however, and Suryong decides that becoming the greatest instructor at a top academy is the best way to do it. Since he’ll be up against tough competition, Suryong will have to use everything he’s got to become a teaching superstar.
