Pangu opened the sky and the three realms separated. The realm of transformation is heaven, the realm of birth is human realm, and the mysterious realm is alien realm. Long Yi is the main god of the alien tribe and the main demon of the alien tribe. There is also a group of people who cannot enter the three realms and live in all three realms. He is in charge of the Dragon Clan, solves the evil problems of the Fantasy Clan, and guides the Dragon Clan to gain experience. However, his true destiny is to lead the outstanding Dragon Clan to return to heaven, so he is revered as the High Priest by the Dragon Clan. Priests are destined to be priests. Only those who are chosen by the heavens and survive four bloody tribulations can hold their posts and continue their clan. The two clans in the alien world have been fighting for thousands of years. The Fantasy clan has cut off its line of priests and expelled its divine dragon clan to gain a glimpse of the secrets of the heaven and dominate the world of the alien world.
