Li Jiuge, a crispy college student in the Department of Modern Literature, was hit by a car. He woke up and traveled back to the wilderness era, becoming Li Jiuge, the son of Chi You, the leader of the Jiuli tribe. In the wilderness era, there were thousands of races and all kinds of strange beasts were rampant. Here, the survival and inheritance of human beings became the most important thing. As the young master of Jiuli, Li Jiuge has the mission of powerful tribe, but when he heard about a tribe called "Yan" in the north and knew that Jiuli would eventually be defeated in the battle of Zhulu, he wanted to change his fate. However, as he learned more about this barbaric era, Li Jiuge felt more and more something was wrong. Until one day aliens invaded, so Kuafu chased the sun, Jingwei reclaimed the sea, Xingtian conquered the sky, Chang'e flew to the moon, Houyi shot the sun... These familiar mythological stories became daily life around me. However, those stories all told the same history: the earth's native humans fought against the alien high-tech civilization and defeated the alien invaders, a tragic epic that protected the inheritance of civilization.
