Murim-chepojeondamjo

Stop the resurgence of the Sinwolmun, a group seeking to rule the world through demons!

Late at night, in a noisy gambling house, a ruffian bets on the family's stolen sword. The legendary Seven-Star Sword, said to control demons, is revealed. Moments later, the Sinwolmun's disciple, Sacheonpaehwang, appears from nowhere. The gambling house is devastated, corpses strewn about. Since that day, the martial arts world has been plagued by a series of gruesome and brutal incidents. The Inryungjo, a martial arts investigation agency specializing in arresting unsolved cases, is dispatched to the scene of these unsolved cases. Recognizing the emergence of a vast dark force, they hunt down its source. Meanwhile, Hui-Yeon, disguised as a man and joining the Inryungjo to avenge her family, is caught on the first day by the group's leader, Beom-Yeop. However, for some reason, Beom-Yeop forces Hui-yeon to remain in the Inryungjo.

Can the Inryungjo prevent the resurgence of the Sinwolmun, once thought lost to legend?
