"Brother Qiangzi, do you also believe what those old guys in the town say about feudal superstition?"

Erdan's face showed a trace of indignation, and after breaking away from Qiangzi's hand, he said loudly: "Brother Qiangzi, I checked it on the Internet, it is not a devil's city at all, but a natural quicksand phenomenon, as long as everyone does not fall into it at the same time, they are not afraid of ......"

Erdan is more than ten years younger than Hadron, after the birth of their generation, the old people rarely mention the tragedy that happened in the 70s, although they also know such a thing, but firstly, they have heard less, and secondly, these people born after the 80s are also bold, and they don't believe much in ghosts and gods.

In addition, in this day and age, even in this remote town, there is already an Internet connection, which can be used to find some knowledge on the Internet that people did not know before, so that these young people do not take the legend of the town seriously at all.

"Erdan, it's not what you think, there's really a devil there, Uncle Scar said, they didn't enter that place at the same time, but the person and the camel who fell in before couldn't be saved, and then Uncle Erzi tied a person with a rope, and then used a camel to pull that person out, who knew that after the person was pulled out, the whole lower body of that person was gone, and Uncle Erduzi was also scared stupid like this......"

Qiangzi didn't want to watch a little brother in a town go to death, so he persuaded him bitterly, when more than ten young adults went out, only two people came back, these things came out of Uncle Scar's mouth, as for the other one called Ertunzi, he was already frightened and delirious, and he died within a few years of coming back.

Na Qiangzi has already remembered, and he still remembers the situation of the funeral of the family in the town at that time, so he is more inclined to believe in the legend of the devil in the desert than Erdan.

"That's fake, can you believe what the second stunned person says?Uncle Scar is just scaring you, I don't want you to go again......"

After hearing Qiangzi's words, Erdan's face turned a little pale, after all, when he heard such a bloody thing, it happened in the place where he was going to go, no matter how bold he was, he began to beat a little drum in his heart, and he could only use this way to increase his confidence.

Just when Erdan and Qiangzi couldn't convince anyone, a person who came with Erdan walked down from the camel, looked at Qiangzi and said: "This gentleman, what you just said is not actually the devil eating people, it is also a very normal geographical phenomenon of quicksand, because once the surface of quicksand is disturbed, it will "liquefy", and the characteristics of water are buoyant, and quicksand is the same.

When people or other objects fall into quicksand, the speed of subsidence depends on the density of the object itself, the density of quicksand is generally 2 g/ml, and the density of people is 1 g/ml......

This person's words made everyone present stunned, even Zhuang Rui only knew that quicksand was a geographical phenomenon, but he couldn't dissect it so straightforwardly, he couldn't help but look at that person and asked, "Who are you?"

Because the few people brought by Erdan were all sitting on camels just now, and there were scarves covering their faces, Zhuang Rui and the others not only didn't know the origin of these people, but they couldn't even tell whether they were men or women.

Even now, it's just Erdan and the middle-aged man who got off the camel, and the other two people don't seem to have any interest in this ruin, and they still sit on the camel, with no intention of coming down.

"Hehe, my surname is Man, I work in Lanzhou Agricultural College, this is my business card......"

The man smiled and lifted the scarf that covered his face, revealing a slightly frosty face, and it could be seen from the lines at the corners of his eyes when he smiled that this person must be at least forty years old.

"Professor of Lanzhou Agricultural University, Vice Chairman of the National Desert Control Foundation......

Zhuang Rui looked at the title on the other party's business card, and immediately respected, China currently has more than 2.6 million square kilometers of desertified land, and it is still spreading at a rate of 3,000 square kilometers every year.

And the desert management work is not just sitting in the office and opening your mouth, you must enter the desert, you need to accumulate a lot of knowledge and technology in practice, from the appearance of Professor Man, you can see that the other party is a person who does things.

"Professor Man, if it were really like what you said, there would not have been a tragedy of quicksand devouring the townspeople back then, perhaps it can be understood that those people were trapped in the depths of quicksand due to struggle, but why is the whole body of the person who was set out gone? Is there still some beast living under the quicksand?"

When Zhuang Rui said this, he did not question what Professor Man meant, but sincerely asked him for advice, the desert, like the deep sea, is a forbidden area for human beings in many places, leaving many mysteries that cannot be solved by science, and this kind of mystery attracts human beings to explore and interpret.

"Young man, do you know why people caught in quicksand generally can't move?"

Professor Man was happy to answer Zhuang Rui's question, and without waiting for Zhuang Rui to answer, he continued: "After the density increases, the sand sticks to the lower half of the human body that falls into the quicksand, which will put a lot of pressure on the human body, making it difficult for people to exert their strength. Even Hercules could hardly drag the trapped out of the quicksand at once.

In the United Kingdom, scientists have calculated and tested that if one foot of a trapped person is dragged out at a speed of one centimeter per second, it will take almost 100,000 Newtons, about the same force as lifting a medium-sized car.

So unless there is a crane to help, it is difficult to pull out the person who fell into the quicksand at once, of course, if it is pulled hard, then before the quicksand "let go", the person's body has been torn off by a strong force, so I conclude that the person who was killed at that time is likely to be the case......"

"Ripped?"

Professor Man's argument made Zhuang Rui and the others a little stunned, they had suspected that there might be some unknown creature under the quicksand, but they never thought that the force of the sand could actually pull a living person off.

"Professor Man, what should people do if they get stuck in quicksand?"

Zhuang Rui was in a cold sweat at this time, if he followed his previous method, if he really explored that area and fell into the quicksand, maybe he would recreate the tragedy of decades ago, thinking about the tragic situation of the separation of his body and head, Zhuang Rui couldn't help but shudder.

When Professor Man saw Zhuang Rui and the others, a smile appeared on his face, and he said: "You don't have to be so afraid, there are still ways to escape the quicksand, that is, people who are trapped in the quicksand, must not panic, move their feet gently, let the water and sand seep into the squeezed out vacuum area as much as possible, so that the pressure on the trapped person's body can be relieved, and at the same time, the sand will slowly become loose."

At the same time, try to keep your limbs as far apart as possible, because the greater the surface area of the sand, the greater the buoyancy will be, and as long as the person trapped in the quicksand has enough patience and gentle movements, he can slowly get out of trouble......"

Zhuang Rui nodded again and again while listening, and at the same time carefully memorized every word that Professor Man said in his mind, for fear of missing a little.

He is still a little afraid in his heart now, he is not afraid of not understanding everything, he is afraid of knowing half of it, like Qiangzi doesn't understand what quicksand is, and he doesn't dare to go to that area, so he won't suffer, and people like Zhuang Rui who thinks he knows the phenomenon of quicksand may fall into it when he walks there.

This is the same as the principle of the antique shop, people who don't understand antique collecting at all, see some suspected antique objects, they will not shoot at all, and there will be no fooling, and those who promote the majestic development of the antique industry are often people who know a scale and a half-armor, and think that they have good eyesight, but they don't know that the objects they buy home are all fakes.

"Thank you Professor Man for your advice, otherwise we would have encountered quicksand and we wouldn't know how we died......"

Zhuang Rui's thanks are very sincere, he also realized a truth from it, there is a specialization in art, even if there is aura in his eyes, it is just a little stronger than ordinary people, although he will die if he is shot, he can't fly out of the quicksand.

"How about it, Brother Qiangzi, did you hear it, Mr. Man is a professor, he said so, he will be fine......"

Although the second egg standing on the side didn't fully understand Professor Man's words, when he saw Zhuang Rui's appearance, he also knew that the other party was very convinced, and there was a smug look on his face at the moment.

For a long time, Qiangzi has been the best guide in the town, and he has made the most money, but now he dares to go to the area where Brother Qiangzi does not dare to go, and Qiangzi is also speechless by experts, so Erdan feels that he has surpassed Qiangzi and become the best guide in the town.

And this time the employer said that as long as he can find the temple lost in the desert, he will give him 100,000 yuan at a time, which also makes the second egg become four eggs, and the adrenal glands are a strong exotic hormone, you know, even if the second egg does not eat or drink for three years, it will not earn 100,000 yuan.

"Professor Man, this is a scientific expedition team, right? If it's convenient, can we go to the quicksand area together?"

Thinking of Professor Man's profession, Zhuang Rui took them for granted as a scientific expedition team, and couldn't help but think of being with them.

You must know that the geographical location of these people who study the desert is not necessarily familiar with Mengzi and Erdan, but the study of desert habits is definitely much stronger than these two tour guides.
