The answers to those questions could not be found, at least Chu Yunsheng could not find them. He still vaguely remembered that Yan Min once treated him as one of their own and told him it had been like this for more than millions of years.
However, Chu Yunsheng did not know what happened tens of millions of years ago. The knowledge he learned from textbooks was limited to the extinction of dinosaurs 65 million years ago, and then it was blank after that.
If it was even further back, there seemed to be a Cambrian geological period as well. It seemed to be an era that had a "big explosion of life". All kinds of different creatures almost appeared magically overnight. The number was so large and the species were so many that it had completely contradicted the normal law of the evolution speed as if there was a hand in the darkness pushing the evolution forward.
This hand, in the age of light, was called "the hand of God" by many scientists!
