After countless years of struggle, my disciple turned the prehistoric world into a top world

Traveling through the prehistoric world, Jiang Chen already had a great way of cultivation but didn't know it. He only wanted to return to the modern world.
However, Honghuang didn't remember the years, and when he was bored, he began to recite various methods of becoming stronger in the past that he had seen in his previous life, and gradually more and more creatures came to listen to his preaching.
Fearing disaster, Jiang Chen had no choice but to dismiss the crowd, but those who didn't want to come to listen to his preaching were all prehistoric and powerful, and then everyone went down the mountain and called themselves Jiang Chen's apprentices.
In front of Zixiao Palace, Master Tongtian: "What can we ask for to become holy in the way of heaven? What Master said, I will cut myself and achieve the Dao of Hunyuan!"
After Nuwa created man, she looked at the sage fruit falling from the sky: "According to Master, I did not create man for sanctification, but to open up the sky!"
As a result, the prehistoric world was completely messed up!
