"Brother Qiangzi, do you believe what those old guys in this town say about feudal superstition?"
There was a trace of dissatisfaction on Erdan's face. After forcefully breaking away from Qiangzi's hand, he said loudly: "Brother Qiangzi, I checked everything on the Internet. It's not a ghost city at all, but a natural quicksand phenomenon.
As long as everyone doesn't fall into it at the same time, you won't be afraid..."
Erdan is more than ten years younger than Qiangzi. After their generation was born, the elderly rarely mentioned the tragedy that happened in the 1970s. Although they also knew about it, they couldn't hear it once they heard it.
There are relatively few people. Secondly, these people born after the 1980s are also very courageous and don’t believe much in ghosts and gods.
In addition, in this era, even in this remote town, the Internet has been connected, and people can search for some knowledge that they did not know before. As a result, these young people have not learned about the knowledge in the town at all.
Treat the legend as one thing.
"Erdan, it's not what you think. There really are demons there. Uncle Scar said that they didn't enter that place at the same time. However, the people and camels who were trapped before couldn't be saved no matter what. Later,
Uncle Erluzi tied a person with a rope, and then used a camel to pull the person out. Who knew that after the person was pulled out, the entire lower body of the person was gone, and Uncle Erluzi was also scared to death..."
Qiangzi didn't want to see a little brother from the town go to die, so he persuaded him earnestly. When more than ten young men went out, only two of them came back. These things were all said by Uncle Scar. As for the other
The one named Er Lengzi was so frightened that he lost consciousness and died a few years after he came back.
Qiangzi had already remembered things by that time, and he still had fresh memories of the funerals of every family in the town at that time, so compared to Erdan, he was more inclined to believe in the legend that there was a devil in the desert.
"That's a lie. Can you believe what a fool says? Uncle Scar is just scaring you. He just doesn't want you to go again..."
After hearing Qiangzi's words, Erdan's face turned a little pale. After all, he heard such a bloody thing happened in the place where he was going to go. No matter how courageous he was, his heart began to beat a little, so he could only use
This way to increase your confidence.
Just when neither Erdan nor Qiangzi could convince the other, a man who came with Erdan got off the camel, looked at Qiangzi and said, "Sir, what you just said
, in fact, it is not that the devil is 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 the same is true of quicksand.
When a person or other object falls into quicksand, the sinking speed depends on the density of the object itself. The density of quicksand is generally 2 g/ml, while the density of a person is 1 g/ml. At this density, the human body sinks
Generally speaking, there will be no disaster in the quicksand, but if the human body struggles in the quicksand, it will be swallowed up by the quicksand..."
This person's words stunned everyone present. Even Zhuang Rui only knew that quicksand was a geographical phenomenon, but could not dissect it so straightforwardly. He couldn't help but look at the person and asked: "Who are you?"
Since the few people Erdan brought were all sitting on camels with gauze covering their faces, Zhuang Rui and others not only didn't know the origins of these people, they couldn't even tell whether they were men or women.
Even now, only Erdan and the middle-aged man got off the camel. The other two people seemed to have no interest in the site and were still sitting on the camel with no intention of getting off.
"Haha, my surname is Man. I work at Lanzhou Agricultural College. This is my business card..."
The visitor smiled and lifted up the gauze covering his face, revealing a slightly weathered face. 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.
"Manjun? Professor of Lanzhou Agricultural College, Vice Chairman of the National Desert Management Foundation..."
After Zhuang Rui saw the title on the other party's business card, he immediately felt respect. 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. Controlling deserts is a lasting undertaking.
Very worthy of respect.
And the work of desert control is not something you can just sit in an office and open your mouth. You have to go into the desert, and you need to accumulate a lot of knowledge and technology in practice. It can be seen from Professor Man’s appearance that he is a professional.
people of things.
"Professor Man, if it were true as you said, the tragedy of the quicksand swallowing up the town residents would not have happened. Perhaps it can be understood that those people struggled and were trapped deep in the quicksand, but the person who was pulled out
, why is the entire lower body gone? Are there any wild beasts living under the quicksand?"
When Zhuang Rui said this, he did not question Professor Man's meaning, but sincerely asked him for advice. The desert, like the deep sea, is a restricted area for humans in many places, leaving many mysteries that cannot be answered by science. And this kind of
Mysteries attract humans to explore and interpret.
"Young man, do you know why people trapped in quicksand generally can't move?"
Professor Man was very happy to answer Zhuang Rui's question. Without waiting for Zhuang Rui's answer, he continued: "The increased density of sand will stick to the lower part of the human body that falls into the quicksand, which will put a lot of pressure on the human body and make people feel uncomfortable."
It is difficult to use force. Even a strong man can hardly pull the trapped person out of the quicksand at once.
Researchers in the UK have conducted calculations and tests. If one foot of a trapped person is dragged out at a speed of one centimeter per second, it would require a force of almost 100,000 Newtons, which is about the same force as lifting a medium-sized car.
.
So unless there is a crane to help, it will be difficult to pull out the person who fell into the quicksand at once. Of course, if you pull it forcefully, the person's body will have been torn apart by the powerful force before the quicksand "let go", so I
It is concluded that the person who was killed at that time was probably in this situation..."
"Torn off?"
Professor Man's argument made Zhuang Rui and others a little shocked. 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 away.
Break.
"Professor Man, what should people do if they fall into quicksand?"
Zhuang Rui was breaking out in a cold sweat at this time. If he followed his previous method, if he really explored that area and fell into quicksand, the tragedy of decades ago might happen again. Thinking about the tragic situation of the body and head being separated,
Zhuang Rui couldn't help but shudder.
When Professor Man saw the appearance of Zhuang Rui and others, a smile appeared on his face and he said: "You don't have to be so afraid. There are still ways to escape from the quicksand, that is, those who fall into the quicksand must not panic and move gently.
Use both feet to allow water and sand to seep into the squeezed vacuum area as much as possible, thus relieving the pressure on the trapped person's body and allowing the sand to slowly become loose.
At the same time, we should also try to keep our limbs as far apart as possible, because the larger the surface area of the body in contact with the sand, the greater the buoyancy will be. As long as the person trapped in the quicksand has enough patience and moves gently enough, he can slowly get out of the trap.
…”
Zhuang Rui nodded repeatedly while listening, and carefully remembered every word Professor Man said in his mind, for fear of making any mistakes.
He is still a little scared in his heart. He is not afraid of not understanding everything, but he is afraid of having only a half-knowledge. Like Qiangzi, who doesn't understand what quicksand is at all. He doesn't dare to go to that area, so he won't suffer a loss. But like Zhuang Rui, he thinks
People who are aware of the phenomenon of quicksand may get stuck wherever they go.
This is the same as in the antique business. People who don’t understand antique collection at all will not take action when they see some objects that are suspected of being antiques. Therefore, there will be no people who will be fooled and promote the magnificent development of the antique industry.
, often people who know only a little bit, think they have a good eye, but they don’t know that the items they buy home are all fakes.
"Thank you Professor Man for your advice, otherwise we would have died without knowing how we died if we encountered quicksand..."
Zhuang Rui's thank you was very sincere. He also realized a truth from it. There is a specialization in skills. Even if there is spiritual energy in his eyes, he is just a little stronger than ordinary people. He will certainly die if he is hit by a gun.
Even if you fall into quicksand, you won't be able to fly out.
"How about it, Brother Qiangzi, did you hear that? Mr. Man is a professor. He said so, and everything will be fine..."
Although Erdan who was standing aside did not fully understand Professor Man's words, when he saw Zhuang Rui's expression, he knew that he was convinced, and a proud look appeared on his face.
Qiangzi has always been the best guide in the town and earns the most money, but now he dares to go to areas that Qiangzi doesn't dare to go, and Qiangzi was even said to be speechless by experts, so
Erdan felt that he had surpassed Qiangzi and became the best guide in the town.
Moreover, this time the employer said that as long as he could lead him to find the temple lost in the desert, he would be given 100,000 RMB at a time. This also turned the two eggs into four eggs, and the adrenal glands kept secreting hormones.
, you know, even if Erdan works for three years without eating or drinking, he still won't make 100,000 yuan.
"Professor Man, you are a scientific expedition team, right? If it is convenient, can we go to the quicksand area together?"
Thinking of Professor Man's profession, Zhuang Rui took them for granted and regarded them as a scientific expedition team, and couldn't help but want to join them.
You must know that these people who study deserts may not be as familiar with the geographical location as Mengzi and Erdan, but their research on desert habits is definitely much better than these two tour guides.
