After the founding of the world by Pangu, the prehistoric world initially evolved. The weak and the strong ate up the world. Innate gods, demons and ancient ferocious beasts dominated the world. It was difficult for the creatures at the bottom to survive. The male protagonist Ling Chen is a little snake with an innate remnant soul who was born and raised. He has an extremely humble origin, with both body and soul disabled. He is on the verge of death at the beginning. In a desperate situation, he awakens the origin of chaos devouring. He gradually becomes stronger by devouring the turbid air of the world, the essence and blood of ferocious beasts, ancient opportunities, and the remnant souls of gods and demons. Along the way, he endured counterattacks and leapfrogged counterattacks, and was gradually involved in the core events of ancient mythology such as the Longhan Catastrophe and the rise and fall of the Lich. He broke the shackles of heaven on the lower-class creatures and finally grew from a humble little snake to the God-eating Snake Emperor who swept across the world, rewriting the counterattack legend of the ancient mythology.
