Liu Yu frowned. Did humans really only have a history of a million years?
Otherwise, why were all humans a million years ago primitive?
Moreover, they were all covered in hair and could only use simple tools?
This made Liu Yu think about it carefully.
Could it be that humans had really evolved?
It wasn't that there was a super advanced human civilization in the previous era.
At this moment, Liu Yu could only shake his head helplessly. In order to reverse time, Liu Yu had used up 50 million drops of world source and it was all used up.
Now, he could only wait for the world source to be sufficient again before he could continue to reverse time or return to the real world.
Of course, after using up 50 million drops of world source and still not finding any clues, Liu Yu naturally wouldn't give up on reversing time. That would be a huge loss.
As for why humans a million years ago were primitive and could only use simple tools, Liu Yu didn't need to think too much about it. As long as he stored up 10 million drops of world source, he could reverse time bit by bit and see everything about humans in this era.
After thinking about it, Liu Yu landed on a tree branch not far away from this primitive tribe.
From Liu Yu's observation, the primitive people of this era had a really tough life. They only wore beast skin and it was imaginable when winter came.
Also, although the primitive people of this era had learned how to use tools, they didn't have much accumulation in terms of invention and creation.
Other than wooden sticks and stone hammers, these few simple weapons, they didn't have anything else.
If he wanted to understand the environment of his ancestor's era, he had to personally experience it.
Of course, he could also observe it for a long time.
However, with Liu Yu's Five Elements Realm strength, his lifespan was simply limitless. It wasn't a big deal for him to personally experience this era.
Liu Yu jumped down and took a look. This primitive tribe had a population of over 30 people. In this era, it was considered a large tribe. This was because under Liu Yu's divine soul scan, there were only a few hundred thousand primitive people on earth. Moreover, they were distributed all over the world. It could be said that they were even rarer than pandas.
Roar roar roar roar
Liu Yu's appearance instantly aroused the primitive people's vigilance. They held wooden sticks and stones in their hands and showed their might to Liu Yu.
However, Liu Yu wasn't angry. The ignorant were fearless!
So what if he was angry?
How could he destroy them?
Naturally, that was impossible.
Liu Yu's eyes sparkled as he connected with the brain of a primitive man. In less than a second, Liu Yu had obtained the language and living habits of the primitive man.
After acquiring the language of the primitive people, Liu Yu also understood their language.
The words' wala ',' huala ',' guala 'and' roar 'meant that everyone was going to attack the prey together. However, none of the primitive men stepped forward.
It was because this prey looked a little like them that they didn't dare to attack immediately.
Although the primitive people from a million years ago did not have the intelligence of modern people, they still had the intelligence of a ten-year-old child. They knew the difference between danger and curiosity.
Liu Yu also wanted to communicate with them, but he lacked the vocabulary. The primitive people of this era could only communicate with a few words, so there was no way to communicate in depth.
With a thought, Liu Yu injected ten drops of World Origin Energy into each of the thirty-three members of the tribe.
After the World's Origin entered their bodies, more than 30 people instantly fainted and accepted the World's Origin's transformation.
Two days later …
