Prehistoric: from Pangu's Creation of Heaven to Invincibility

Xu Fang traveled through the prehistoric times, witnessed the creation of Pangu, felt that his own strength was insignificant, and decided to survive until the end of the world! The beast measures the calamity? If you fight life or death, what does that have to do with me? Three clans competing? You are turned upside down, but I am as motionless as a mountain! Lich fight for hegemony? You go ahead and fight, it's none of my business to blow your brains out! No matter how overwhelming the outside world is, I will cultivate steadily! When I come out of seclusion, the bloody tribulation will end with me! At that time, dust will return to dust and dust will return to earth, the sky will rise to the sky, the earth will return to the earth, and it will be sent to the west!
