[Which university is Lao Fang a professor of geography? Will the headmaster be able to pull him back? 】

[This Bobby, I have to give 94 points, don't ask why, because I watched the live broadcast at high speed, and I was deducted 6 points! ] 】

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

[The old party understands that it is really much. 】

"It's not that I know more, it's that I know before you." Bi Fang shook his head, "Now you know it too. ”

[Ah, high emotional intelligence! 】

[Why do you feel like you've heard of it?] 】

[Lao Fang said it in the first live broadcast, I remember it very clearly! ] Let's put it this way, just for this sentence, this person I'm a fan of! 】

Bi Fang's analysis can be said to be amazing, the barrage and gifts have been brushed again, Pan Wei was envious, and he shouted harder, and the sweat on his face flowed.

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

"The lowest." The fat man turned the button, and he was already turning his head.

Now I feel hot, all sunburned, 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 was easy to roll over when he went up, so he could only follow under the sun.

Sunburn.

Sunburn is caused by excessive exposure of the skin to ultraviolet rays, and signs and symptoms appear within one to twenty-four hours.

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

In severe cases, it may be accompanied by fever, headache, palpitations, fatigue, nausea, vomiting and other systemic symptoms.

Bi Fang looked at the few people with red and swollen faces in the car, tightened the white hood on his head, and walked towards a huge rock in the distance.

It was already eleven o'clock, but Bi Fang did not stop, but continued to walk.

Said to let these people go to the hospital in a day, not a minute late!

In a hurry, Bi Fang also kept telling some experiences and stories to fill this boring time.

"Humans have lived in the harsh environment of the desert for quite a long time, but they have never conquered the desert and can only face it."

"What taught me this was a Kriya friend of mine, whom I met when I went to Xinjiang."

[Wait, Kriya? Is there such a nation in our country? 】

[Listen to the name like a foreigner? Fang Shen has such a wide range of friends? 】

[Shouldn't it?] 】

"Of course not, where did I get my foreign friends?" Bi Fang shook his head, it was a man he had met by chance when he went to the desert to investigate the number of red fox groups.

"The Kriya people, belonging to the Uyghur people, are quite a legendary local pastoral people, but very few people know about them."

"It is said that the Kriya people are a branch of the Guloulan people 2,000 years ago and have been living in the desert since ancient times. Of course, these claims are unfounded, so let's just listen to them. ”

"The man had lived in the desert since he was a child, and he said to me that I was very impressed, saying, 'Why fight and spend energy fighting against things that you cannot 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 to find water and capture prey, where throttling is much more important than open source!"

Bi Fang stretched out his hand and pointed to the large desert in front of him, and said heroically: "Have you seen it? This desert? The fifth largest desert in our country! Any idea since when it started to form? ”

"50 million years ago! The Indian plate collides with the Eurasian plate! The uplift of the Qinghai-Tibet Plateau has created this vast and boundless desert! ”

The wind swept the ground, and the yellow sand flew.

"Here, mountains and basins alternate, 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 Yin Mountains on the east side, all of which surround here!"

Bi Fang stretched out his palm and squeezed it suddenly.

In front of all the audience, the scene of the mountain mountain uplift thousands of years ago seemed to emerge, as if the gods descended and turned into a moat, turning this place into a Jedi.

It's away from the ocean.

Warm and humid air currents come from a long journey.

Most of the water vapor has already been lost.

It was also blocked by mountains and plateaus.

Water vapor loss is exacerbated by the air flow over the mountains.

By the time I arrived, it was unusually dry.

Drought and little rainfall.

However, drought alone is certainly not enough.

Where does such a vast expanse of sand come from?

High mountains surrounding the basin.

There used to be glaciers that were much bigger than they are now!

As the snow melts,

A large amount of flowing water converges along the foothills towards the basin,

Numerous rivers and lakes are formed.

Flowing water carries the sand and gravel "scavenged" from the mountains,

or create vast alluvial plains,

or gradual deposition at the bottom of the lake.

Eventually, in the interior of the basin, sedimentary layers up to hundreds of meters thick were formed!

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, which means that in 1 million years, there will be a layer of sand about 120 meters thick in the river basin, which is equivalent to a 40-story building!"

"And in fact, the sediments of the Tarim Basin, farther away, are even deeper than that! These sediments have also become the main source of sand in China's deserts! ”

"If you want to conquer such a desert, you can't just rely on a jeep and a few more boxes of water." Bi Fang's tone was light, but everyone knew that he meant something.

[Weird, read the ID card! ] 】

[I feel that those people are not in a good state as Fang Shen. 】

[With my medical clinical experience of three consecutive bachelor's, master's and doctoral studies, they have sunburned! 】

[Anyway, it's already twelve o'clock, didn't Fang Shen say that he wanted to avoid this time? ] 】

"Ah, is it twelve?" Bi Fang pretended to realize, "I feel that the situation is okay, so I keep walking, it seems that I have to find a place to rest!" ”

Hearing this, Du Chuan and the others' faces became extremely bad.

They feel that the other party is doing it on purpose.

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

But when it was finally time to rest, they also wanted to drive to a shady place, which was too sunny.

Pan Wei rubbed his face, the tiny dandruff like fish scales still fell, which made his heart tremble, and he took out another bottle of water and wiped it on his face.

"This is the second box, use it less." There was a reminder from the fat man next to him.

"Got it, got it." Pan Wei said impatiently.

But when they watched Bi Fang get into a place where the car could not drive at all, and the rest of the place was completely unshaded, they were all dumbfounded.

It was not easy for Lao Tzu to find such a place, if you don't die in the sun, I won't have the surname Bi.

Wait, where is this?

Holding the drone into the crack under the boulder, Bi Fang looked at the few people outside the cave and sneered.

If you don't live for three months, can it be called hospitalization?

Funny.
