Since the victory of the demon religion in the Majeong War a few decades ago, the demon religion has been successful enough to command the world, but for Seok Munpyeong, who belongs to the most distant position of the Demon Kyo, the battle for the next Demon Emperor is also a matter of another world. I thought it would have nothing to do with the messy situation of the current pontiff Chunma, who was supposed to hand over the throne to the next chief minister, but one day he was called by one of the candidates for the next pontoon, Privy Councillor Pyo Young. Immediately, he becomes a member of Ma Young, the secret guard of Kyōju's closest associate, and is tasked with protecting Gyoju. A difficult mission to chase after a thousand horses, a super-climax master who hates being bothered more than anything else. Kyoju finally appears in front of Seok Mun-pyeong, who is desperate for a mission that even his own life cannot be guaranteed.
