None of them expected this result. Yue Guanchao was a little confused and continued to ask: "You mean after the earthquake and the mountain shaking, the debris generated by the mountain collapse directly submerged the Shahai King City, and then the sand covered the rubble ruins. , completely filled in the rocks, forming a flat sandy land on the west coast. We can’t find the Sand Sea King City because they are still buried under a certain rock formation. As long as we can’t reach that rock formation, there will be no Find a way to find them."
Yue Guanchao's explanation was completely reasonable. Song Siyuan nodded to him: "You are right, the Shahai King City is probably under the shelter of the broken Red and White Mountain."
Having said that, Yue Guanchao became curious about this point: "If this is the case, then do we still need to look for it? The Shahai King City is located at the foot of the Hongbai Mountain. Once the mountain collapses, the force generated by the broken rocks will be It seems that a trebuchet attack on the city is enough to completely blow up the royal city. What we found may not be a sand sea royal city, but a ruins smashed by rubble."
"Especially since this ruin is still hidden under some rock formations, it is even more impossible for us to dig it out. Furthermore, even if we find the royal city, we may not be able to enter it. The city is covered by the desert. There is no way to dig it out anymore.”
Everyone has already realized this, and there is a haze in everyone's mind. Song Siyuan seems to have different ideas from them, snapping her fingers and retorted: "My ideas and yours are different. You first take a look at the murals in the underground palace. Upload the image about the Red and White Mountains, and then look at the Red and White Mountains today.”
Following Song Siyuan's signal, they observed the current Red and White Mountain. Combined with the photos of the underground palace murals, they could clearly see that the large spiers at the eastern foot of the Red and White Mountain no longer existed, as if they had been completely erased from the geographical location. .
Judging from the distance from the tributary river to the mountain peak, the length of the cracked mountain is at least two to three kilometers. At the same time, the nearly vertical slope of the mountain seems to prove that the mountain was directly cracked, as if It was directly cut open by the sky-splitting axe, and the cut mountain was dumped directly on the Shahai King City instead of being broken into stones and then rolled down. "
"What does this mean?" Yue Erpao scratched his head, completely confused.
Song Siyuan reminded: "Such a large volume of rocks, covering the Shahai King City, should form a high slope or low mountain with a considerable height. But why, what they see now is flat land, even as high as the Hotan River. On a par?"
This shows that before the collapse of the Shahai King City, it was likely that it collapsed due to the influence of the underground cave. The entire rock block carrying the King City sank downwards during the earthquake, thus forming a giant sinkhole.
Then, the Hongbai Mountain broke directly from the mountain side, and the huge mountain crashed down on the west bank under the pull of gravity, completely covering the sinkhole, just like a giant lid shrouding the sinkhole in Shahai King City. This situation also happened. A unique and subtle structure - the Stone Dome Sinkhole!
Under this structure, the stone dome is equivalent to the cover of the sky, covering the tiankeng with the fractured mountain. It is like a protective shell, blocking the broken rocks of the mountain for Shahaiwang City. At the same time, the tiankeng also blocks Shahaiwang City. The layers carry it, and no matter how many stones are broken, they can only fall on the rock cover and cannot harm the royal city under the rock layer.
After thousands of years, sand has completely covered these rock formations, and has completely filled in the depressions formed by the sinkholes. To a certain extent, it can be regarded as restoring the ground state before the geological disaster. Based on this situation, it is speculated that this area It is completely explainable that the sandy land can have the same horizon height as the Hotan River.
Song Siyuan was afraid that they would not be able to digest this abstract concept, so she led them into the central tent and to the sand table.
Then, she took out two palm-sized stones and placed them around the Sand Sea King City. She then covered the model of the Sand Sea King City with a cardboard, and then placed many finger-sized gravels on top, and began to move towards it. Pour sand over cardboard gravel. .
As the sand filled the gaps between the gravel on the cardboard, a flat layer of sand gradually formed on top of the stone, completely burying the gravel. At this point, Song Siyuan casually placed several wooden figures on the sand layer.
She motioned for everyone to look at the existing structure of the Sand Sea King City and explained the significance of her doing so: "If it were replaced by a more common structure,
To explain in layman's terms, we can compare the sinkhole where Shahai King City is located to the first floor. Then, where we are standing now can be roughly regarded as the second floor above the sinkhole. "
"With the Sand Sea King City completely sinking into the sinkhole, only the second floor is exposed to the horizon, and the first floor has completely sunk into the ground. In addition, all the space below the second floor is covered with sand. It is impossible for us to find the Sand Sea King City. It seems much more reasonable.”
Her eyes lit up and she said loudly: "After all, if we stand on the second floor, we will never be able to find the things on the first floor. If we really want to find the Sand Sea King City, we have to break through the broken rocks under the rock formations. Only in this way can we enter the sinkhole where Shahai King City is located."
At this point, her meaning was already very clear: "I believe that the Sand Sea King City must exist in a sinkhole under the huge rock formation. As long as we find the way down to the sinkhole, we can find the Sand Sea King City."
"Is there really such a strange structure under the sky? How could the Shahai King City just fall into the sinkhole?"
Even though Queenie is a desert herdsman and knows the topography of the desert, he doesn't know much about this structure. He probably has never seen such a coincidental geological structure. This coincidence seems to be artificially designed. He After looking at the geological model given by Song Siyuan, I felt that the structure of a sinkhole under the sand layer was very clever and strange.
Song Siyuan has rich geological experience. She has realized the ingenuity of this structure and explained: "I don't know the specific situation, but it can also be explained. The earthquake was not caused by natural factors, but by Yu Pei. Caused by the mysterious power, the scope of the earthquake was limited to the Red and White Mountains and the west bank of the Hotan River, which happens to be where the Sand Sea King City is located."
"The precision of the earthquake and the location of the rock collapse proved that it was the result of human control. Perhaps Queen Shanshan had long known that there was a rock cavity underground in the Shahai King City, and then she activated the mysterious power to sink the entire Shahai King City into the sinkhole. Then huge rocks fell down and covered the sinkhole, forming a stone sky."
She paused and said in a mysterious tone: "As for why there is an underground cavity under the Sand Sea King City? It should be related to the geological structure of the Hongbai Mountain."
The Hongbai Mountains were formed due to the uplift and splitting of the Tarim Basin. These peaks do not look high, but in terms of geological structure, the uplift structure directly splits the rock layers and lifts them upwards, which can easily form certain cavities underground.
The location of the Sand Sea King's City is only a few hundred meters away from the Red and White Sacred Mountain. In terms of the length of the mountain, these few hundred meters are almost negligible. It is equivalent to the Sand Sea King's City being built at the foot of the mountain. It is very likely that it will be built in hundreds of millions of years. Before the formation of geological structures, certain cavities had been formed underground in Hongbai Mountain, so this also meant that the Sand Sea King City was built on the underground cavities.
"The geomagnetic disturbance a thousand years ago was equivalent to using the cavity to protect the Sand Sea King City. This is entirely possible."
Seeing Song Siyuan's explanation, Yue Guanchao understood how to find the royal city: "Does that mean that as long as we find the way into the underground cavity, we can enter the Shahai Royal City?"
Song Siyuan nodded and confirmed: "Theoretically, this is the case. As for where the passage into the underground cavity is? We can roughly guess that it is at the location of the old river."
"Why?"
They all became curious and urged Song Siyuan to explain the reasons.
Song Siyuan nodded towards them: "I took a rough look at the location of the old river just now. There are no ponds near the river. The dry sand also makes the outline of the old river very clear. A dry river can be clearly seen. On the sand."
"If this happens, it means that there are some underground rivers under the dry river channels. Perhaps the underground rivers can be used to enter the rock cavity."
When Song Siyuan said this, they already understood what to do. Everyone got out of the tent and started to check the outline of its tributaries along the river. As she said, the west bank full of ponds showed clearly the outline of the old river channel.
Yue Guanchao said: "Since the entire river is the same, I don't have to look for any location. Maybe I can find the underground river wherever I dig. It's good to determine the location first and blow it up with bamboo explosives." Dig a little."
Just as they were told, Yue Guanchao chose a spot a hundred meters away from the campsite, completely dug out the thick salt crust on the river, and began to dig out dry fine sand. Then, they stuffed homemade explosives into the dug trench and pulled it up. The lead came to the tent a hundred meters away.
As everyone retreated from the explosion range, Yue Guanchao picked up the fire stick and lit the primer. These artillery leads sent sparks all the way, bringing the fire to the sand nest a hundred meters away. With a loud bang, yellow sand began to ripple a hundred meters away. The dust and even the stones in the sand were cracked into pieces, causing flying sand and rocks to scatter for dozens of meters.
When all the dust settled, they walked to the sand pit. The sand layer, which was more than ten meters thick, had been blown away by gunpowder, and the rock layer at the bottom had been exposed to the public.
Yue Guanchao and the others went down to the rock formation. The rock formation under the river looked like the edge of the rock formation created by the squeeze of two mountains. They could clearly see that there were countless gaps in the rock formation, which were distributed in a streamlined shape within the scope of the river, pouring downwards. With several buckets of water, you can clearly see that the water flow is absorbed by the gaps and gradually penetrates deep into the ground.
Seeing this scene, Song Siyuan's eyes showed excitement: "It seems that we have found the edge of the sky cover. This should be the edge of the cracked rock formations at the east foot. There should be underground rivers under these gaps. Look down and blast a hole. Look, you’ll know if what I said is true.”
