Prehistoric: Signing at the Heel of Pangu for a Hundred Thousand Years

Lin Xuan traveled through chaos and started with a weak green lotus. After binding the sign-in and clock-in system, he silently signed in at Pangu's feet for a hundred thousand years. Until that day, when Pangu was about to swing his ax to open the sky, he suddenly turned around and grinned: "Brother, you have been hiding from my heels for so many years, and why don't you come out and help your brother?" Lin Xuan was confused. It turned out that this eldest brother had known for a long time that he had secretly cultivated for a hundred thousand years! Unexpectedly, when the Heavenly Tribulation arrived, the system suddenly sent a prompt: "Ding! It has been detected that the ultimate copy of the Great Desolate World has been opened - please assist Pangu, the host, to complete the mission: Survive!"
