Daejangbuui Geom

Even though he has acquired the world's greatest martial arts skills, he does not seek fame and thus does not enter the martial arts world. He is called a true great man. Admiration and respect are met with jealousy. Even the royal family... and the greatest martial arts masters try to undermine the great man's status. Finally, a great man who has accepted an unwanted call and entered the martial arts world. His sword is hotter than the fire and brimstone of hell. The world will burn...!
