Li Taiyi never expected to wake up in the Primordial World and become Donghuang Taiyi. The problem is, he's arrived too early. The Beast Calamity is still underway, and he's still an egg, not even hatched yet. Thinking of the coming War of the Witches and Demons, in which barely one in ten of the demon race will survive, he and his elder brother Dijun will die in battle, and only Lu Ya will remain of the Golden Crow clan, Taiyi can't help worrying about his own fate, his brother's fate, and the fate of the demon race. So Taiyi works hard at cultivation, starting right there inside his egg, and gets Dijun to start pushing himself from inside his egg too.
After hatching, he binds to a Fate-Defying System. From then on, Taiyi cultivates his way to transcendence, protects his brother, and achieves the Great Dao.
