Koul (코울)

\[By the Author that brought you \<Murim’s Debt King> ] War has vanished from the Murim. However, even an era of peace demands its scapegoats. In an age where the fate of an entire sect is decided by official martial arts duels, prestigious families secretly buy and sell "Shadows"—human training tools forced to learn the martial arts of rival clans. These living punching bags are raised solely to ensure their masters' victory, only to be discarded without a single trace once their purpose is served. But the clans picked the wrong people to throw away. Now, the bloody revenge of the abandoned begins!

Ganghyeok is ruined. His gym business is failing and there's no way he can pay off his debts. But one night, while reading his favorite author's latest webnovel, he gets sucked into a world of martial arts fantasy and wakes up as a child monk in the Shaolin temple. There, he must apply his knowledge of modern fitness to survive their strict training, juggle the friends and enemies he makes along the way, and find a way to get back home.
