The God of War is Leveling Up

The greatest martial artist on the continent and the supreme Martial Emperor who unified the martial world—Suhyeok. He had achieved everything, yet a lingering emptiness in his heart remained unfulfilled by his yearning for family... In the end, he crossed dimensions using the power of sorcery, but what lay before his eyes was... *"I was in a coma for five years in a hospital!? And what's with this system window floating in front of me!? Black Sage, you big-mouthed bastard! You said you'd send me back to my world! Why the hell is everything so messed up!?"* During the five years he lay unconscious, his family had been struggling to pay his hospital bills... "For my family's sake, I need to make money—fast and a lot of it." The strongest Martial God of the Hwan Continent, Suhyeok! Now Awakened, he begins his journey to level up.
