The World's Best Kunlun Tavern

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.
