Gongsun Guang, a space scientist, is involved in an experimental accident and transmigrates through a spatial passage to a planet in the gap between universes: Kesaixing. This is a world powered by Origin Force, where countless civilizations from across the universe have been drawn for one reason or another, creating a society in which all races coexist. The races are scattered across Kesaixing in the form of tribes. Among them are Chinese Qi cultivators from ancient times, who sought immortality. After meeting a group of Han Chinese who call themselves the Tianming Clan and learning of their wish to return home, Gongsun Guang offers them a proposal. Thus begins the struggle for supremacy among the myriad races of Kesaixing, setting them on the path to the fusion of civilizations. And the ultimate goal of it all is to break free of Kesaixing and return to their respective civilizations!
