If human masters evolved directly in the African Rift Valley, then the evolutionary process is likely to be shortened by thousands of years, or even tens of thousands of years!

In that case, what will the world become?

Lin Feng thought about it, and couldn't help but feel his heart surging and could not calm down for a long time.

At this time, Wells chuckled, mercilessly breaking Lin Feng's fantasy, saying, "Civilization can only evolve through communication.

Africa's geographical location determines that it is not a good place for communication. The dense plateau divides each piece of land, forming many independent ecosystems and forming closed environments.

In this way, there will be no communication, and civilization will inevitably degenerate. Even if history starts again, I don’t think they can break this situation.”

Of course Lin Feng understood this principle, but he couldn't help but feel unwilling to accept it. He always wanted to distinguish but couldn't find a real argument.

Human evolution is actually the process of brain evolution.

Increased brain capacity requires a large amount of high-phosphorus proteins, such as fish.

In addition to the convenient communication conditions, human settlements next to the ocean or river can also provide humans with a large amount of food with high phosphorus proteins and promote brain development and evolution.

Another benefit of communication is to allow the evolved excellent genes to spread rapidly into the blood of the nation and speed up the progress of civilization.

Of course, this also includes the absorption of excellent culture and experience.

If a nation is addicted to the interaction between chickens and dogs and lives a life that does not interact with the outside world, then today in Africa is their tomorrow.

This has been proven by humans in 10,000 years, and there is no need to repeat the same mistakes.

So what Wells said was right.

If time goes back and history repeats itself, Africa's self-sufficiency way of survival will still stagnate their civilization.

...

That night, Wells lived in White's cabin, while Lin Feng made a place to live among the branches for Zhao Yajing overnight.

He himself stayed under the tree, half alert and half resting for a night.

the next day.

According to the established plan, Lin Feng returned to his original camp alone and began to relocate the base.

But the simple hammock between the branches seemed to make Zhao Yajing sleep uncomfortable. She seemed unwilling to continue sleeping in the hammock. In addition, she felt that it would take many days to relocate the items in the original camp, and it would take a long time to rebuild the tree house, so she simply returned to the original camp and lived more comfortably.

So she was determined to go back with Lin Feng.

Lin Feng still chose to accommodate this compatriot. After all, he didn't know how long he would live here. He left a spear and plenty of food for Wells, so he took Zhao Yajing back the same way.

The way back was very smooth, and the bloody smell left by the little thief dragon scared away the similar people nearby.

Even though they encountered a few other similar creatures on the way, the two of them chose to avoid them, but they were unable to avoid them, so Lin Feng took the initiative to go up and rush.

Lin Feng, who was unwilling to waste ammunition, waved his long sword and used clusters of electric current to make those hateful screams, which made Zhao Yajing, who was unaware of the truth, feel that Lin Feng is extremely brave.

When the two of them passed by the place where they met the smart dinosaurs, Lin Feng couldn't help but feel alert.

At some point, the sound of gold and iron intersecting came faintly in the wind. At first, he thought he had heard it wrong, but when he turned his head and saw Zhao Yajing's surprised look, he couldn't help asking, "What did you hear?"

"It seems like... the sound of a blacksmith, but it's impossible. How could someone make a blacksmith in this wilderness?"

Lin Feng tilted his head and carefully identified it, and found that the sound became more and more similar, and from the beginning the single metal intersecting, it turned into a messy sound. In addition to the metal iron sound, there were also shouts and screams.

There are even... cheers and applause?

"It's not a ironclad." Lin Feng said solemnly.

"Yes, it's a bit like a noisy market." Zhao Yajing echoed.

Before we knew it, a faint purple mist gradually floated in the jungle. The light in the dense forest was relatively dim. Lin Feng only focused on distinguishing the sound at the beginning and did not pay much attention to the others.

When he noticed the purple mist, the surrounding jungle was already shrouded in it, and only the few trees around them were still thin.

"Go away!"

Zhao Yajing experienced a fog and broke into this strange world. Now that she saw this strange fog again, she suddenly panicked and practiced and urged Lin Feng to leave.

Lin Feng reached out to his waist, strengthened the sound wave detection input signal of the belt and shot into the thick fog.

However, the signal seemed to be a muddy bull, and received no response. On the contrary, the noisy sound became louder and louder.

"Go to support."

Lin Feng made a quick decision, took off the round shield on his back and held it in his hand, took out the individual sight-gear belt from his backpack, and led Zhao Yajing into the fog.

The principle of fog is actually due to the difference in air temperature and earth humidity.

Countless missing times in history seem to be related to fog. Perhaps because suddenly one space intersects another space, which will cause a great difference in temperature and humidity, so theoretically, heavy fog will occur.

This is true for the disappearances in Bermuda, as are many disappearances in history.

But no matter what, this weird purple color is too evil and makes the scalp numb.

Lin Feng led Zhao Yajing to follow the sound for a few steps, and immediately realized something was wrong.

The primitive jungle was originally covered with various vines and shrubs, but at this time they had disappeared without a trace, and there was no collision on this stretch of road.

Lin Feng wanted to go back to his previous place, but after recycling, he found that his original foothold was already covered by thick fog.

At this stall, Lin Feng seemed to touch something, and he reached out and touched him and was immediately overjoyed.

It was a tree, a huge tree.

This is the first tree he encountered after traveling through the fog for so long.

He patted Zhao Yajing, walked several steps through the giant tree, and then suddenly walked out of the fog and saw a sunny scene of ancient trees and forests.

At the same time, the noisy sound was amplified countless times, and the sound waves rushed towards Lin Feng frantically.

At this time, Lin Feng confirmed that this was not the sound of a blacksmith or the noise of the market, but...

It's the sound of fighting!

They seem to have come to an ancient battlefield!

Outside the dense forest deep in them, two teams were fighting on the grassland!
