Regarding this point, Song Siyuan shook her head and explained: "This kind of desert swamp often appears together with quicksand. As long as people accidentally step into it, it is difficult to escape. According to the distribution pattern of these ponds, they are almost all over the Hotan River. On the west coast, it’s difficult to completely avoid these ponds when we move around.”
She paused and continued: "But actually when we were looking for the ruins, we didn't feel like we were being pulled into the mud or swamp at all. This means that when it doesn't rain, these desert pools are completely dry. Just like the sand layer, rainwater will accumulate and form ponds only after moisture appears."
"If there really were swamps, the water in these ponds would have been sucked into the swamps long ago. They would not have formed reservoirs. It would be impractical to have swamps under the sand."
After listening to the words of several people, Gu Hengxi's eyes flashed suddenly, and he took a long breath and reminded: "Is it possible that there are still some peaks under the desert hinterland, just because the sand directly covered the peaks? It makes the whole area look like a flat desert.”
At this point, Gu Hengxi had obviously encountered similar terrain before, and his words became serious and he said: "I have seen this kind of terrain in Northern Xinjiang. I remember that we once found a canyon in the sand in the desert of Northern Xinjiang. "
The so-called canyons in the sand are completely different from normal canyons. Normal canyons are mostly concentrated in mountainous areas or river valleys, while desert canyons appear on flat sand, with the horizon as the highest point, and cut deep into the desert underground.
Looking at the past at ordinary times, you can only see flat sandy land without any shadow of the canyon. Only under abundant rain can you see the entire canyon hundreds of meters deep. With abundant water washing, the canyon appears on the sand. on the ground.
To use a metaphor, these sandy canyons are like a crack splitting directly along the sand. You can see underground rivers rushing under the canyon. Even the sand on both sides of the canyon will form a sandy waterfall due to the height difference. , constantly falling into the abyss and rushing into underground rivers.
This kind of canyon is a desert canyon!
Tracing back to their origins, these canyons are actually cracks in the rock formations caused by geological movements in ancient times. Later, after thousands of years of vicissitudes, these rock formations were gradually covered by desert, forming completely flat sandy land.
When the groundwater is not abundant, the sand will completely fill the gaps in the canyon. You can't tell how deep the gaps in the rock formations are. Even if you walk on the canyon, there will be no danger. Only when the groundwater rainfall is sufficient, the magic of the canyon will be revealed. Reveal it!
When the rainy season arrives, excess groundwater will gather together through underground rivers. This groundwater has the power to change the underground structure and can continuously wash away the cracks in the rock formations. It may even open up new cracks in the rock formations to form underground rivers.
Under the powerful force of this flowing water, the sand and soil are completely unstoppable. The excess groundwater will continue to wash away the gaps in the rock formations that remain deep in the desert, and eventually the quicksand will be completely washed away.
Then, after the gaps that were originally filled were not filled with sand, they were gradually exposed from the flat desert. If you didn't know the situation, you would feel that huge canyons appeared out of thin air in the desert. These rock cracks were like the Creator tearing apart the sand. With the opening opened, you can directly see the underground river channel through the sand layer. ..
When the flood season passes and the water volume decreases, the underground rock formations will gradually stop flowing. At this time, the force of washing away the sand will completely disappear. The sand on both sides of the rock formation will continue to fall into the gaps due to the height difference, as if it is continuously filling the gaps. Soil until the canyon is filled up, a new flat sandy land will be formed.
Many people who don't know the truth call this kind of canyon that appears and disappears during the flood season the devil's mouth. Once it appears, it will be the end of the world that will swallow up living creatures and sediment.
Speaking of this, Gu Hengxi was obviously not joking. He explained: "Although the characteristics of the desert canyon are different from the current situation, it can at least prove one thing - since this desert can hide the canyon, then, it can hide the canyon. Some tall rock formations or simply stone mountains are very likely to appear, and it is not just our imagination."
This hint from Hu Nu opened the door for everyone. Wang Yuanlu seemed to have remembered something and interjected: "Indeed, I suddenly remembered that Shandong's "Shouguang County Chronicle" once recorded a strange mountain..."
This mountain is called Jingshan, located more than ten miles southwest of Shouguang County. It is neither high, nor wide, nor wide. The total area of the rocks is about the same as a water tank, and the highest part exposed above the ground is only half a meter. In actual terms, it is about the same width and height as a bench. Anyone with hands and feet can stand on the top of the stone.
Such a stone mound cannot be called a mountain. The reason why it can be called a mountain is entirely for another reason.
It turns out that most of the mountain is buried in the soil. This mountain, which is about the size of a bench, is actually the "top of the mountain" that emerges from the ground. Someone with good intentions used this stone pier as the center to excavate. After digging down nearly a hundred meters of earth and rocks, we could not dig out the bottom of the stone. On the contrary, the bottom of the stone became wider and wider, and it actually had the undulating momentum of a mountain.
Only then did they understand that Jingshan is not big because most of the mountain is under the soil layer. As for its volume under the soil layer, no one has been able to completely dig out and measure it since ancient times. It is because no one knows It's so big and deep that I don't know why I named this stone pier Jingshan!
At this point, Wang Yuanlu became serious: "These rock formations in the desert are probably the bodies of some mountains. This is consistent with our guess."
After listening to so much, Song Siyuan felt that their statement was very possible, and said: "It is indeed possible to have high mountains hidden in the desert, but why only the west coast area has deep rocks? Let's look at it based on geological logic. Is it understandable? Because some geological disaster occurred in this area on the west coast, some rocks appeared, and the Sand Sea King City completely disappeared here."
She had spoken so clearly that everyone had already guessed the meaning of his words. Xu Xiake's eyes lit up, "A disaster that can change the rock formations, isn't it an earthquake?"
"It's an earthquake!" Xu Xiake nodded, convinced that his guess was accurate.
Song Siyuan cast an approving look: "Yes, I think only earthquakes can change the rock structure on the west coast, and then tall rock formations can appear under the sand layer. As for the specific details, I will continue to study them."
At this moment, they had completely left the tent, and neither the small blackboard nor the sand table had been brought out. Song Siyuan had to use the things in her hands to start analyzing the impact of the earthquake on the rock formations, and at the same time, she also tried her best to guess the logic and feasibility of it.
About an hour later, she took a long breath, and it seemed that the results had been achieved.
Song Siyuan calmed down, coughed a few times and said, "I think the situation on the west bank of the Hotan River begins with the destruction of the Shanshan Kingdom a thousand years ago. About a thousand years ago, the Tang army defeated the Western Regions. The Western Regions, including the ancient Shanshan Kingdom, were included in the Tang Dynasty. , when General Ashina decided to pursue the victory, the last queen of the ancient Shanshan Kingdom, under the influence of the fish pendant, completely disappeared with the Shahai King City. It was also in this year that the private family book of Dunhuang City Soldier Mo Shisan recorded the death of the bird. On that day of the accident, there were raging fires and clouds, and at night the birds collided with each other and cried blood."
Mentioning these, Song Siyuan's face became mysterious: "The two events may seem unrelated, but they both happened in the same year. At the same time, there are common elements in the records of the two events. The earth shook and the mountains shook. , strange celestial phenomena, from this point of view, it seems that these strange celestial phenomena appeared because of the demise of the ancient Shanshan Kingdom."
"Combined with the fact that geological disasters such as earthquakes have occurred here, I have reason to judge that the destruction of Shahai King City in about the 23rd year of Zhenguan seems to be related to earthquakes caused by magnetic field disorders. I even think that whether it was Subsequently, the birds cried blood in Dunhuang City, or the appearance of the undead, these situations can be regarded as the chain reaction caused by the disappearance of the Sand Sea King City, just like dominoes, with a tight logic."
"How do you say that?"
Everyone was very curious about this.
Song Siyuan continued to explain: "I remember when we went to look for the wild geese in Yanshan Mountain, I mentioned to you that there is a structure in the birds' brains that can sense changes in the magnetic field and adapt to the earth's magnetic field to help They find directions, migrate and settle. This structure is not only found in geese, but is commonly found in the brains of birds."...
"If a bird loses its direction, in addition to being chased by natural enemies, the only thing left is magnetic field disorder. I heard the story of the birds crying blood in Dunhuang City.
When the incident happened, I already suspected that there was something wrong with their organs that sensed magnetic fields. They were probably affected by the magnetic field, so they hit the body without any purpose. They could not tell the direction and their temperament changed drastically. It happened. It shows that the magnetic field in the desert has been disrupted. "
"The most noteworthy point here is that the date of the accident was the year Li Shimin died, which was probably the 23rd year of Zhenguan. It was also the same year that Shahai King City was destroyed. A geological disaster suspected of an earthquake occurred here. Earthquakes can produce , is also caused by the disorder of the earth’s internal magnetic field.”
At this point, Song Siyuan's eyes widened: "Think about it, the earthquake in Shahai King City and the birds weeping in Dunhuang City happened at the same time due to magnetic field disorder in the same year. If this is not a coincidence, it is probably caused by some people. It was done on purpose.”
Then, she took out the photos on the murals of the underground palace and said: "At that time, General Ashina recorded that they saw the disappearance of the Sand Sea King City. I suspect that the power of the fish pendant caused magnetic field disorder, which caused this area to be destroyed. An earthquake was produced, which not only caused the royal city to disappear, but also deterred foreign enemies. The situation described by this general just proved that an earthquake really existed here at that time."
"This can also be mutually supported!"
