Monsters and Gods

This is the Naver Webtoon [Monsters and Gods], based on the martial arts web novel by author Hanjungwolya. It's a story about Mok Gyeong-un, the founder and first Heavenly Demon of the Demonic Cult, to which Cheon Yeo-un from Nano Machine belongs, within the Hanjungwolya universe. As those who have seen Nano Machine know, Mok Gyeong-un is the person Cheon Mu-seong, a descendant from Cheon Yeo-un's future, originally intended to bring back to stop Geukdosin. He is an individual with immense power and talent, so it might be a good choice for those who enjoy overpowered characters.
