After walking for a while, Lu Yuan accidentally discovered that the stones of this mountain were very different from ordinary stones.

Lu Yuan began to pay attention to the stones under his feet.

Soon Lu Yuan found a strange stone.

The stone looks very much like a turtle.

When Lu Yuan first discovered it, he thought it was a turtle fossil.

However, he soon confirmed that the stone was not a fossil, but a Gobi stone.

"Nature's magic is truly magical!"

Lu Yuan found a random place to sit down.

He carefully admired the strange stone in his hand. The more I looked at him, the more satisfied I became.

He found that this stone was really amazing, especially the turtle shell part, how the crack on it looked like a "longevity" character.

This is simply a strange stone of turtle longevity.

This kind of strange stone Lu Yuan once heard people mention, once a "turtle although longevity" strange stone was auctioned for a full 50 million!

Lu Yuan happily admired the masterpieces of nature.

"Next time, it would be great to give this piece to Professor Sun as a birthday gift!"

Lu Yuan admired it for another moment, and then carefully collected the strange stone.

Then Lu Yuan carefully explored the surrounding environment.

This time, he was surprised to find that this mountain was a treasure mountain.

He soon discovered agate ore in the mountains, followed by jade ore.

In addition to these regular gemstones, the quality of the Gobi stone here is also very high.

Since more than 30 years ago, the whole world has been popular to collect Gobi stones.

In recent years, the price of high-quality Gobi stone has also been rising.

When Lu Yuan was a backpacker, he knew a traveler.

At that time, when this traveler was traveling in the Western Regions, he once spent 500 yuan to buy a Gobi stone.

When this traveler first bought it, everyone laughed at him for being stupid.

But a year later, he sold the Gobi stone to a Ryukyu collector for 60,000 yuan.

You must know that it was more than ten years ago, and the Zhuxia coins at that time were much more powerful than they are now.

Lu Yuan looked at the mountain and quickly knew what it meant.

It's endless wealth, it's wealth that can make people crazy.

Lu Yuan turned on the positioning system and found that this place turned out to be the junction of the three kingdoms.

"I'm in trouble now!" Lu Yuan frowned.

Lu Yuan could already imagine the consequences of the news of this treasure mountain.

Wealth is something that can drive a person, an organization, or even a nation crazy.

For the sake of the wealth of this mountain, it is likely to lead to a war between the surrounding three countries!

After thinking of this, Lu Yuan decided to hide the news of the discovery of this treasure mountain.

Although he knew that the mountain would be discovered sooner or later, it would be tempting to hide it for a while, at least to delay the conflict.

Lu Yuan rested here for a night, and continued to move forward the next day, this day he had only walked for less than two hours, and suddenly found a cliff in front of him, and there was a cave halfway up the cliff.

Lu Yuan's curiosity became for a while, and he decided to go to the cave for a walk.

When he and Sun Jia were looking for information about the Sahara, they found that archaeologists had found more than 30,000 prehistoric petroglyphs in the Sahara Desert.

Lu Yuan also wants to try his luck now, maybe he can also find a few petroglyphs.

Lu Yuan thought of the prehistoric petroglyphs, and his heart suddenly became hot.

He quickened his pace, and within a few minutes he climbed up the cliff and into the cave.

This cave is quite big, Lu Yuan looked around, and suddenly he found that there was something on the cliff wall on the east side of the cave.

He walked over and saw that the cliff was really a petroglyph.

He couldn't hide his excitement, and immediately took out the live broadcast equipment, wanting to share the joy in his heart.

Lu Yuan just took out the device and was about to start the live broadcast, and soon he stopped what he was doing.

At this time, he remembered the mountain he had discovered yesterday.

It's too close to that mountain, if you do this live broadcast now, someone will definitely come here, and Baoshan will definitely be discovered at that time.

Thinking of this, Lu Yuan dispelled the idea of preparing for a live broadcast.

He put away the live broadcast equipment again and carefully observed the petroglyphs.

The style of the petroglyphs here is completely different from what Lu Yuan has ever seen.

He found patterns of various fish and deer on the cliff face.

Then he discovered patterns of mammoths and hippos.

"Mammoth!" Lu Yuan felt a little strange.

At this time, he turned on his computer with a puzzled face.

After some searching, he finally understood why he was confused.

According to previous studies, mammoths live in the northern part of Eurasia.

It has never been recorded that mammoths ever lived in the hot Kunlun continent.

You know, mammoths can't stand the heat.

Mammoths appear in this place, except that many years ago it was not hot and there was plenty of water and food.

According to geographical studies, the Sahara region has been dry and hot since 2.5 million years ago.

The natural environment suitable for mammoths only existed 2.5 million years ago.

And judging from the other patterns on the petroglyphs, the place was still very wet when prehistoric humans painted these petroglyphs.

Are these petroglyphs more than 2.5 million years old?"

Thinking of this, Lu Yuan was first shocked.

2.5 million years, which is too long for Lu Yuan.

You must know that it has only been 100,000 years since the appearance of Homo sapiens.

Could it be that this is left by the third generation of human beings, Lu Yuan suddenly remembered the statement mentioned by the intelligent housekeeper, the five generations of human civilization.

At this time, Lu Yuan couldn't help but turn his head to look at the rest of the cave.

In order to find out the situation in the cave, he decisively released his divine sense.

Soon he found something skeletal in the depths of the cave.

Because these things were buried, it took Lu Yuan a lot of effort to dig them out.

This pile of bones has become fossils because of its age.

Fish bone fossils, deer head fossils, and buffalo horn fossils were found in Lu Yuan.

But what excited Lu Yuan the most was that he also found a giant human skull fossil.

This fossilized skull is significantly larger than the skull of modern humans.

They were about the same size as the Giant Clan, and as far as Lu Yuan knew, the Giant Clan was the third generation of humans.

They left the Earth 2 million years ago, and the petroglyphs here are at least 2.5 million years old.

Lu Yuan judged from this that these petroglyphs should have been left by the giant clan when they were still in a primitive society.

Lu Yuan felt that there should be no problem with his inference, modern human civilization had only developed for thousands of years and reached the current level.

The giants could not be worse than modern humans, and it is completely understandable that they developed the ability to obtain interstellar navigation for 500,000 years.
