LEOUL

Born as the son of a wealthy family, 'Jang Geon' was destined for ruin. To turn his fate around, he had to live a simple life under the guidance of a virtuous monk. Given to the frugal monk 'Gyeongmok' at Shaolin Temple, Jang Geon spent his days in rough cotton robes, barely getting by on plain rice... While enduring hunger and minimizing movement in his daily life, he stumbled upon martial arts and managed to apply his mindset of thrift to it…?

"The Zenith of Martial arts becomes the instructor for a bunch of troublesome students?!" The Demon Cult Leader Seok Woncho, a monster who surpassed the Blood Cult Leader. Do you know who killed him? "Ha Mubaek." "But, why are we talking about him...?" "He's coming to our Fierce Dragon Division as an instructor." ... This is bad. We're fucked! Ha Mubaek, the master who annihilated both the Demon Cult and the Blood Cult, ends up being sent as an instructor to a martial arts training institution due to a clash of power struggles. He probably thought he could hide his identity and live a quiet life this way, but it seems his reputation is creating chaos. His mission? Solve the issues of students prone to exploding in fits of anger, educate the trashy Water Dragon Academy, and yet... things are getting strangely chaotic...? What’s this? A genius lunatic instructor is a first, right?!
