In addition, more than 2 million years ago, the stone tools made by the Homo erectus who lived here, the ash layer left by the fire, the leftover animal bones, and the bones of Homo erectus, as well as the skull of Homo erectus that Chen Rui wanted to find the most.

To discover this, you can only find it by going to the place where Homo erectus once lived and dwelt.

Li Wanhao and the four of them stood in front of the rock wall to watch the petroglyphs, took out their mobile phones, and the camera kept shooting the patterns of the petroglyphs.

Chen Rui turned around and left the rock wall, intending to find a place nearby where Homo erectus once lived and lived.

The place shouldn't be too far away.

Because, given the circumstances around Homo erectus, the frequent occurrence of jungle beasts, and the lack of 'advanced' means of transportation such as horses and boats, the range of human activities at that time was not too wide.

The place should be under a cliff wall sheltered from the wind and rain, or in a safer, warmer cave that can defend against the attacks of predators.

Chen Rui began to look nearby.

Walking on the rugged and steep Gobi, full of rocks, cliffs, and bare rock peaks, Chen Rui walked like a fly.

After searching the vicinity for more than two hours, I did not find a cliff or cave where Homo erectus lived.

However, there was also an unexpected surprise.

On one of the rock walls, water seeps out from the cracks in the rock wall, flows down the rock wall, flows to the ground, and forms a small puddle on the ground, the puddle is not large, the area is about a few square meters, and the water is crystal clear.

Finding a water source in the desert is a big surprise for anyone.

Water in the desert represents life, the hope of survival. This is by no means a lie.

Five people set off from Matru. Brought a dozen buckets of water. These dozen or so buckets of water alone take up nearly half of the space in the two cars.

In the meantime, water was replenished once in a Bedouin village.

The daily consumption of water is still very large.

Drinking water, cooking, cooking, simple washing, etc.

The five people try to save water as much as possible, and even wash their faces with several people sharing a basin of water.

The five of them had been bathing for four or five days, and their bodies were greasy. The body smells of sweat and sourness, no one should laugh at anyone, everyone is the same.

Now that the water source has been discovered, everyone can finally have a luxury.

Chen Rui walked over quickly.

Some disappointed Chen Rui.

Chen Rui found a lot of animal footprints and feces next to the small puddle.

Normally, where there is water, it is absolutely impossible to hide from the desert dwellers who live here.

Although the water looks very clear and very clean.

But Chen Rui knew that the water was undrinkable, and it was polluted by animal feces, which was not only dirty. And the water contains a lot of pathogenic bacteria, such as: E. coli, Salmonella.

Drinking water containing pathogenic bacteria can not only make people have diarrhea, dysentery, and various diseases, but also lead to dehydration and weakness.

Still, something is better than nothing.

The water on the rock face is clean and unpolluted.

Not only is it drinkable, but it is definitely the best mineral water in the world, flowing through rock formations and rich in various minerals that are beneficial to the body.

Chen Rui fixed the bottle in his hand to the rock wall, dripped water into the bottle drop by drop, and after two hours, the bottle could be filled.

Leaving the bottle here, Chen Rui continued to search.

Chen Rui had good luck again, and finally let him find a cave about 4 or 500 meters away from the water source.

Chen Rui is not sure if this cave is the cave where Homo erectus once lived for more than 2 million years.

Chen Rui planned to go into the cave to investigate.

Maybe the water here is more abundant, but of course relatively speaking.

The vegetation here is very luxuriant.

It is overgrown with shrubs such as flower sticks, single trees, and sand canopy dates, and it is very dense.

Chen Rui walked into the cave.

Here is a natural cave.

Someone has lived there, that's for sure.

On the walls of the cave, you can see some traces of sharp cutting and cutting, as well as some traces of regular lines and symbols that are obviously left by people.

The further I went, the more certain I became.

On the walls of the cave, there are traces of smoke and fire.

Chen Rui is almost certain that this is the cave where Homo erectus once inhabited more than 2 million years ago.

Chen Rui also found something special.

Someone has been in a cave.

On the ground, there were camel hoof prints, human footprints, no dirty ashes, leftover firewood, bones from unknown animals, food scraps, and a piece of wrapping paper.

Chen Rui guessed that it was probably a desert traveler, or a camel caravan had already discovered this place and used it as a 'post station' to rest and recuperate on the way.

After all, there is a water source less than 4 or 500 meters from here.

It is almost certain that this cave is the cave where Homo erectus once lived here more than 2 million years ago.

Chen Rui began to purposefully search for traces of their existence.

A discovery that will surely shock the world will also lift the fog of history.

More than 2 million years, compared to the Earth's age of 4.6 billion years, is only a very short time.

Yes, for human beings, it is an extremely long, long time.

For more than 2 million years, the changes to the earth have been a sea of vicissitudes.

More than 2 million years ago, the Sahara Desert was a green grassland, and now it is an endless desert.

Mount Everest, which is more than 2 million years old, is only more than 4,000 meters, and now it is 8,848 meters, and in fact, more than 40 million years ago, Mount Everest was still a vast ocean.

That's the vicissitudes of life.

It has also undergone a lot of changes.

The traces of more than 2 million years of Homo erectus life have been sunk into the ground by geological changes and the accumulation of dust and soil.

Chen Rui used the earth escape technique and drilled into the ground.

Soon, there was a very big discovery.

Chen Rui made a lot of discoveries at a depth of 14 meters above the ground.

The first thing to be found was some round, square fire pits.

The ash layer of the fire pit was very different from the dirt in Chen Rui's sight.

Immediately afterwards, it was discovered that a large number of stone tools, carbonized wooden tools, and some shells.

The discovery of the shell was overjoyed for Chen Rui, and it was an astonishing discovery.

Although it was just a few shells, there was a lot of news revealed to Chen Rui, and it also revealed a secret that shocked the world.

For one, this tribe of Homo erectus came from the seaside, because only the seaside has such shells.

Second, there is a large river nearby, which connects to the Mediterranean Sea, or the Red Sea, the Indian Ocean, and the Homo erectus migrated to this place far from the sea through the guò river.

In fact, Chen Rui has long guessed that not far from the vicinity, in more than 2 million years, there is a big river. (To be continued......)
