[Lao Fang is a geography professor who ran away from which university? Can the principal bring him back? 】

[I must give 94 points for this wave. Don’t ask why, because I was deducted 6 points for watching the live broadcast on the highway!]

[Too strong, too strong, I would like to call this analysis the strongest! 】

【Lao Fang really knows a lot.】

"It's not that I know better, it's just that I knew it before you did." Bifang shook his head, "Now you know it too."

【Ah, high emotional intelligence!】

【How do you feel like you have heard of it?】

[Lao Fang said it during the first live broadcast, I remember it very clearly! Let’s put it this way, just because of this sentence, I am a fan of this person!]

Bi Fang's analysis can be said to be astonishing. The barrage and gifts came again, which made Pan Wei envious. He shouted even harder, sweat dripping from his face.

"Turn the air conditioner down!" He turned to the fat man and said.

"It's the lowest." The fat man turned the button and it was already turned to the end.

It feels hot now, all due to the sun. The temperature itself is not high, but the faces of the four people in the car have begun to glow red.

Bi Fang was able to walk in the shadow of the sand dunes because he was small alone, but the jeep couldn't drive there, and it would easily roll over if it went up there, so he had to follow in the sun.

Sunburn.

Sunburn is caused by overexposure of the skin to ultraviolet rays, with signs and symptoms appearing within one to 24 hours.

Skin changes range from mild erythema with scaly formation to pain, edema, skin tenderness, and bullae.

Severe cases may be accompanied by systemic symptoms such as fever, headache, palpitations, fatigue, nausea, and vomiting.

Bi Fang looked at the people in the car with red and swollen faces, tightened the white hoods on their heads, and walked towards a huge rock in the distance.

It was already eleven o'clock, but Bifang did not stop, but continued walking.

It is said that these people should be admitted to the hospital within one day, not even a minute late!

While on the road, Bi Fang kept telling some experiences and stories to fill this boring time.

"Human beings have lived in the harsh environment of the desert for a long time, but they have never conquered the desert. They can only face it."

"The person who taught me this truth was a Keriya friend of mine whom I met when I went to Xinjiang."

[Wait, Keriyas? Do we have this ethnic group in our country? 】

[The name sounds like a foreigner? Does Fang Shen have such a wide range of friends?]

【Shouldn’t it be?】

"Of course not. Where did I get my foreign friend?" Bifang shook his head. He was a person he met by chance when he went to the desert to investigate the population of red foxes.

"The Keriya people belong to the Uyghur ethnic group. They are a quite legendary local herdsmen, but few people know about them."

"It is said that the Keriya people are a branch of the ancient Loulan people two thousand years ago. They have been living in the desert since ancient times. Of course, these claims are unfounded. Just listen to them."

“That guy had been living in the desert since he was a kid, and he said something to me that really stuck with me, and he said, ‘Why fight and expend your energy fighting something you can’t change?

'"

"Since then, I have known that if we want to survive in the desert, we must adapt our bodies to its harsh environment, instead of trying our best to find water sources and capture prey. Here, reducing expenditure is more important than increasing revenue.

Much more!”

Bi Fang pointed at the vast desert in front of him and said boldly: "Have you seen it? This desert? The fifth largest desert in our country! Do you know when it began to form?"

"50 million years ago! The Indian plate collided with the Eurasian continental plate! The uplift of the Tibetan Plateau created this vast desert!"

The new wind is blowing across the ground, and the yellow sand is flying.

"Here, mountains and basins appear alternately. The Kunlun Mountains, Altun Mountains, and Qilian Mountains on the south side, the Pamir Plateau on the west side, the Tianshan Mountains and Altai Mountains on the north side, and the Helan Mountains and Yinshan Mountains on the east side all surround this place!"

Bi Fang stretched out his palm and squeezed it tightly.

In front of all the audience, the scene of the mountains rising thousands of years ago seemed to appear in front of them, as if the gods descended and turned into a chasm, turning this place into a desert.

It's far away from the ocean.

Warm and moist air travels long distances.

Most of the water vapor has already disappeared.

It also encountered obstacles from mountains and plateaus.

The airflow increases the loss of water vapor as it passes over mountains.

It was already extremely dry when we arrived here.

Drought and little rain.

However, drought alone is of course not enough.

Where did such vast expanses of sand come from?

The high mountains surrounding the basin.

There were once much larger glaciers than they are now!

As the ice and snow gradually melt,

A large amount of flowing water gathers along the foothills toward the basin,

Many rivers and lakes were formed.

The running water carries sand and gravel "scavenged" from the mountains,

Or create vast alluvial plains,

Or it gradually accumulates at the bottom of lakes.

Eventually, a sedimentary layer hundreds of meters thick was formed inside the basin!

After Bi Fang described these words, everyone was shocked.

It turns out that such a monotonous desert has such a magnificent history?

"Even today's Hotan River carries about 6 million cubic meters of sediment a year. This means that in one million years, there will be a sand layer about 120 meters thick in the river basin, which is equivalent to a 40-story high-rise building.

!”

"In fact, the sediments in the Tarim Basin further away are deeper than this! These sediments have also become the main source of sand in our country's deserts!"

"If you want to conquer such a desert, you can't just rely on a jeep and bring a few more boxes of water." Bifang's tone was calm, but everyone knew what he meant.

[Weird, I’m reading my ID card!]

[I feel that those people are not as good as Fang Shen.]

[Based on my medical clinical experience from three consecutive bachelor’s, master’s and doctoral studies, they have already been sunburned!]

[By the way, it’s already twelve o’clock now. Didn’t Fang Shen say that we should avoid this time? 】

"Ah, is it twelve o'clock already?" Bi Fang pretended to realize, "I felt the situation was okay, so I kept walking. It seems I need to find a place to rest!"

Hearing this, Du Chuan and others' expressions became extremely grim.

They think the other party did it on purpose.

How could a wilderness master not even be able to judge the time accurately?

But it was finally time to rest, and they wanted to drive to a shady place quickly, as it was really too sunny here.

Pan Wei rubbed his face, but tiny flakes of skin like fish scales still fell off, which made him frightened. He took out a bottle of water and wiped it on his face.

"This is the second box, use less." Another reminder came from the fat man next to him.

"I know, I know." Pan Wei said impatiently.

But when they watched Bifang get into a place that was completely inaccessible to cars and with no shadows in the rest of the place, they were all dumbfounded.

It took a lot of effort for me to find such a place. If I don’t expose you to death, my surname will not be Bi.

Wait, where is this?

Holding the drone and drilling into the crack under the giant rock, Bi Fang looked at the people outside the cave and sneered.

If I don't stay for three months, can I be hospitalized?

funny.
