Baekbo

From MangaUdates: Finally, Byeokwu has mastered it—the Sacred Art of Grand Clarity, one of the most precious arts of the Gonryun Clan. But nothing he learned in seclusion could’ve prepared him to understand the state of things one hundred years later. Leaving his clan behind, Byeokwu starts a new life as a chef at the Gonryun Tavern, determined to help the owner turn a profit. And if his noodles are good enough to tempt the Divine Demon of the Bloody Heaven into changing his ways? Surely, there are worse things.

"I'm finally free!" After fifteen years of locking myself on top of a mountain, I returned to the world in order to compensate for the youth I had wasted during those past years. As I descended from the mountain, I made a resolve to pay all of my master's grace by completing the Ten Virtuous Deeds as soon as possible and then live the rest of my life in leisure. With a sense of pride, I took the first step forward, but somehow things didn't go as expected and the situation became increasingly complicated... Join him now on his journey to become the strongest in the world, in a place filled with betrayal and tears rather than justice and laughter, on the rivers and lakes!
