Prehistoric: Reborn as a tortoise, with understanding that defies heaven

Yang Gui traveled to the ancient world and became a giant turtle in the North Sea.
So I am the material used to repair the sky, the giant turtle?
Yang Gui was confused.
How can this be possible!
I want to save myself!
Fortunately, he has a superb understanding and the Chaos Pearl to conceal the secrets of heaven;
He secretly developed in this ancient land and began to save himself...
When Gonggong angrily crashed into Mount Buzhou and the saint proposed to use the giant turtle in the North Sea to support the sky, Yang Gui sat on the North Sea with a calm expression, "You want to chop me down?"
