Wen Qingshan continued: "Generally speaking, it is still possible to find satellite signals within a few meters of the ground with a satellite locator search, but if it is too deep, there is nothing you can do. Therefore, it is unlikely that they were caught in an accident.
It was buried in quicksand, because in that case, the signal from the satellite positioner they carried should still be able to be searched, so I estimate that they probably accidentally entered an underground cave while escaping from the sandstorm."
When Wen Qingshan said this, I said doubtfully: "But if they just entered an underground cave, why couldn't they come out of that cave even after four or five days?"
"I have also thought about this. I think the most likely possibility is that the entrance to the cave disappeared shortly after they entered the cave."
"What!? You mean the entrance disappeared?" I thought I heard it wrong, because I really couldn't imagine that an entrance that originally existed would disappear for no reason.
Wen Qingshan nodded.
"How is this possible, unless they have entered a void barrier or a so-called time and space tunnel."
But Wen Qingshan waved his hand and said: "No! This cave should have nothing to do with the void barrier, but a real cave."
"Since it is a real cave, how could the entrance disappear?"
Wen Qingshan explained: "You don't know that in the desert, the sand dunes will shift under the influence of the wind, which will cause the terrain environment in the desert to change to a certain extent. This is why someone has clearly discovered that in a desert
I found an ancient city ruins, but when I looked for it again, I couldn’t find it no matter what.
One of the reasons. So I think that the sandstorm must have caused the sand dunes in that area to shift, thus revealing the entrance to an underground cave that was originally buried under the sand dunes. In order to avoid the sandstorm, they hid in that
Inside the cave, I never thought that the sand dunes would move again and cover the cave entrance."
Just as Wen Qingshan said this, Ai Shan happened to pass by the door. Wen Qingshan saw him and shouted to him: "Brother Ai Shan! Please wait a moment."
Aishan stopped and asked in slightly stiff Mandarin: "Is something wrong?"
Wen Qingshan smiled and said: "I heard that Brother Aishan is the most familiar with the terrain of Lop Nur. I just want to ask, do you know if there are underground caves under Lop Nur?"
When Ai Shan heard this, he immediately nodded and said: "Of course! There are not only underground caves under Lop Nur, but also a very huge underground lake!"
"Underground lake!?" Ai Shan's answer surprised us all.
Aishan continued: "When I was a child, I heard from the old people in the village that there was a huge underground lake under Lop Nur. I didn't believe it before, but once, I encountered a strong sandstorm alone in the hinterland of Lop Nur and lost my way.
After drinking it all, just when I thought I was dead, I suddenly found a pool of clear water in a sand dune depression.
At first I thought it was a mirage, but when I got closer, I saw clearly that it was really a clear water. It was only because of that clear water that I was able to walk out of the hinterland of Lop Nur alive. From then on, I believed that there was indeed a clear water below Lop Nur.
There is an underground lake, and as the dunes change, groundwater seeps out in some low-lying areas, forming pools."
After listening to Ai Shan's story, Wen Qingshan seemed to have thought of something. He frowned and muttered: "There is such a thing. Is it possible that the theory about Lop Nur wandering around the lake is true?"
I quickly asked: "What is Wandering Lake?"
Wen Qingshan explained: "Because the drying up of Lop Nur has always been difficult to explain from a scientific perspective, Swedish adventurer Sven Hedin proposed a theory about Lop Nur's migration in the 1980s. He believed that there was a
In the northern and southern lake areas, the river water entering the lake carries a large amount of sediment, which raises the lake bottom after deposition. The original lake water naturally flows to another lower ground.
After many years, the elevated lake bottom will lower again due to wind erosion, and the lake water will flow back again. This cycle is 1500 years. This theory was once widely accepted, and then someone proposed a new point of view based on this theory.
It is believed that there are two lakes in Lop Nur, one yin and one yang. The yang lake is the former water country, while the yin lake is underground. As the yin and yang change, the lake area will also change."
"In other words, Lop Nur has not dried up, it's just that the water has sunk into the ground."
"According to the wandering lake theory, so to speak."
Wen Qingshan's words gave Dong Xiaodan a glimmer of hope. She said excitedly: "If this is the case, could it be that my dad and the others entered the cave where the underground lake is located!?"
"It's hard to say now, after all, everything is just based on theoretical analysis, but if there really is an underground lake under Lop Nur, then their chances of survival will be greatly improved."
The few of us were talking when we suddenly heard a sound from outside the door, which sounded like the sound of an iron door opening. We hurriedly walked out of the door, and sure enough, the heavy iron door was slowly opening.
When the door was fully opened, Long Yi and Chen Biao were seen standing at the door.
They just went to attend a meeting, and now they are back, and they don't know what news they brought.
A few of us immediately stepped forward to greet him. Dong Xiaodan was the first to ask: "How is it? Can we set off to search now?"
Long nodded: "Everyone, hurry up and get ready. The vehicle will pick us up in five minutes."
"Holy shit! Just five minutes!?" I felt a little uncomfortable with such a tight time schedule, but I had no choice but to obey. I didn't care about so much anymore and rushed back to the room to change.
clothing.
Five minutes later, I hurriedly walked out of the room with my backpack on my back and found that the twenty members of the Red Dragon Special Forces had already assembled. They were truly well-trained elite warriors.
Others also walked out of their respective rooms one after another, including Dong Xiaodan, who also carried a large backpack. When Long saw her, he immediately stepped forward to stop her and said, "Miss Dong, you can't go with us."
"We are already here, just let me go with you. If you let me stay in this dark place alone, how can I stay there!" Dong Xiaodan pleaded.
But Long Yi said in a non-negotiable tone: "No! We have already agreed before, you stay here and wait for news!"
Just as she was talking, several desert jeeps parked outside the gate. Seeing this, Dong Xiaodan immediately walked out without saying a word, carrying her backpack. Her posture seemed to be that she was going to use her bow forcefully. But Long Yi did not stop her,
He just said in a calm tone: "Miss Dong, if you insist on going, this search and rescue operation may be delayed or even canceled. In order to find them as soon as possible, I advise you to obey the arrangements."
Dong Xiaodan was shocked by Long Yi's words. She stopped and turned to look at Long Yi and then at me. Tears seemed to be welling up in her eyes.
I knew she was worried about Professor Dong's safety, but after all, this was an arrangement that had already been decided, and it was probably not Long Yi's place to make the decision, so I hurriedly stepped forward to comfort her and said, "Don't worry, I'm still here!
I will find Uncle Dong and the others."
Dong Xiaodan raised his head and looked at me: "No matter what, you must find my dad."
I nodded firmly, looking at her trusting eyes, I suddenly felt an irresistible sense of responsibility.
A group of people got on the jeep, and the convoy drove along the passage to the ground. After leaving the base, the convoy drove directly into the vast desert.
It happened to be noon at this time. The four-wheel drive desert jeep we were riding in was very powerful, but the comfort level was very average. There was no air conditioning and all the windows were open. Only then did I realize that it is really not that hot in the desert.
, the heat wave hit me, I just felt sweat was pouring out, and my throat seemed to be on fire. I had to drink water to quench my thirst. However, the air quality was very good, and the visibility was very good.
So high that you can even see the sand dunes in the distance.
The convoy was speeding through the desert. Since there was no road to follow, it could only rely on the satellite navigation system to guide the direction.
Wen Qingshan and I sat in the same car with Long Yi, Batur, and Ai Shan. On the way, Ai Shan introduced us to the situation in Lop Nur. He told us that the climate in Lop Nur is unpredictable, and sandstorms can come at any time.
, even if there is no wind now, the weather seems good, but it does not mean
Just be safe. Once the wind blows, you must be careful. Because the surrounding area is too open, a light breeze may turn into a storm. When a sandstorm comes, you must stop moving immediately and find a way to avoid the wind, but remember not to hide.
In low-lying areas, otherwise there is a risk of being buried by shifting sand dunes.
In addition, special attention should be paid to the temperature difference between day and night. Because the desert is dry and lacks water, and there is no vegetation, the intensity of sunlight during the day is very strong, and dry sand and gravel absorb heat faster than areas rich in water.
A lot, and at night, because there is no sunlight, the heat will be released quickly, resulting in
The temperature drops rapidly. In Lop Nur, the highest temperature on the ground can reach 70 degrees during the day. If you bury a raw egg in the sand, it will turn into a mature egg in less than two minutes. After the sun sets, the temperature will rise again in a short period of time.
Temperature differences that drop below ten degrees to as high as fifty degrees may make it difficult for the human body to adapt.
After listening to Ai Shan's words, I couldn't help but secretly say something bad, because I walked in a hurry when I came the day before yesterday. I didn't bring any thick clothes at all, and I didn't know if I could bear it at night.
Long Yi, who was sitting in the passenger seat, seemed to know that we were not well prepared, so he turned around and said, "Don't worry, the car has not only prepared enough food and water, but also warm clothing."
After hearing what he said, I felt a little more at ease.
