Dogwanggangnim

Lee Gun-Ak, a herbalist and mercenary, lost his head on the battlefield, but that head... was reattached to the body of the Twelve Princes of the Sacheon Dangmun? The palace infighting over the emperor's throne, the Demonic Cult's reinvasion of the Central Plains, the grand plan of the bloodline that the leader of the martial arts world is trying to lead, and the world's best merchant shaking the martial arts world with the power of money. The martial arts world is in a truly chaotic time!! A small typhoon that started in Sacheon, a rural corner of the Central Plains, covers the world. Until a mere herbalist who only knew the names of herbs becomes the king of poison who melts tens of thousands of people with poison!

"Come! I will show you the majesty of a true one-man army!"
