The Dark Ages: Fighting Against the Old Gods, Starting from Cultivation of Immortals

(This book combines a system similar to the Cthulhu mythology with Chinese immortality cultivation) In the beginning, there was no starry sky, only a living, infinite stone. Nameless old gods squirm upon it, they are the laws of chaos. Until a goddess with the head of a human and the body of a snake, based on a baby born from a stone, created the first batch of "flawed products"-human beings. So the ants learned to wield their swords at the gods. They call themselves: Ancient Gods. And the baby in the stone is named "Xuan". He is the most human-like God and the most God-like man. When the anger of the old gods crushed hope, and when the creator Nuwa returned to silence, it was he who triggered the ax under the boulder that was bigger than despair. With one axe, he split the infinity and cut out the heaven and the earth. Billions of years later, a high school student accidentally got this opportunity. The ancient gods were erased by time, but they still want to destroy mankind. What kind of terrifying choices will an ordinary high school student face?
