Li Tian accidentally transmigrated to the Primordial World, where he met Fuxi and Nuwa. The two great deities used him as a template to mold humans from clay, making Li Tian the Ancestor of Humanity. He was then bound to the God of War System, which let him exchange for secret manuals, cultivation techniques, and elixirs from every anime.
Donghuang and Dijun founded the Demon Tribe's Heavenly Court, ruling with cruelty and feeding on humans. Enraged, Li Tian attacked the Heavenly Court alone. The Ghost Tribe, Demon Tribe, and Sea Monster Tribe seized the chance to attack as well, setting off the first war among the myriad races since Pangu created the world. Li Tian won the human race a place to survive in the Central Plains, while the other races settled in the four corners of the world. In the process, all his meridians were destroyed. Yet the Heavenly Court never abandoned its resolve to annihilate humanity. Before disaster could erupt, Li Tian endured countless hardships and returned to his peak. The human race's constellation battle arts, the demon race's sorcery, the devil race's demonic arts, the divine race's divine power, the ghost race's soul arts: which is stronger?
