Of course, the entire mountain will not be fake, but part of the mountain should be built entirely from the air.

The collapse of the ground here proves that the entire valley was raised by people half a person, and then covered with soil and weeds. I don’t know the structure below the valley because of the collapse, but I believe it is a bracket and a fixed plate structure. This is very familiar to the architecture.

This leads to no big trees here, because the soil layer is not thick enough, this layer of elevated ground should be like a shell.

If the engineering troops were set up, it would be possible to complete this project in one day with more people, but I believe it is unlikely, because too many people are bigger, the goal is even bigger. I believe that the project in this place was built bit by bit under very hidden circumstances. This kind of hidden project is generally related to the army.

This kind of project is not only hidden, but also very strong. I guess it is possible to make holes in the mountain by using cannons. People can't even dig up any flower heads when stepping on them or digging. A little bit of it should be full of stones.

And I know where the entrance is, it should be at the largest tree. That tree is a symbol. If it grows tall, the root system should be directly buried.

The place where I ignite the fire should be near the entrance, and the bottom should be hollow.

I am so dark now that I can't go back, but when I think of me pushing the cigarette under the stone and ignite such a big fire, I don't know if there will be any problems. I don't know if the collapse here is caused by the fire on the hillside.

I ran carefully in the grass, and all the way to the edge of the collapsed basin, where the collapsed fault was.

I saw a camouflage layer that was about the thickness of my arm. The bottom layer was cement steel bars, and a huge rock layer in the middle, which was poured onto the cement. It looked no different from mountain rocks. These stones were countless neutral stones, with soil, gravel and weeds on it.

If someone digs here and digs into the rock layer, he will not be able to dig it down. He will not find the Mercury Reverse Below.

Because the strata on both sides were dislocated, I saw countless holes collapsed, and the breaks were all grass roots. When I opened them, I saw that the bottom was indeed empty.

I looked in and thought the space inside would be cramped. This floor was set at a distance of half a person at the bottom of the real valley. But when I climbed in half, I found that I couldn't touch the bottom. I put some hay into it and pulled it in. I found that the hay was burning and falling down like a meteor.

It was amazingly deep below. I felt it for a moment and found that it was not only cold inside, but also had a strange airflow.

I shouted, the echo was very empty, and my cold sweat came down. I realized that under my feet, there was a huge space. I touched the edge where I was, touched down from the side, and touched the rough cement wall.

The top of a tall cement building I built under an abyss, I don't know if this building is a building or a huge cement tower.

How deep is this valley? I took a deep breath and stood up. Since my bachelor's degree in architecture saved my life several times, I have read all the college courses in my spare time. Now I feel that there is no big problem with taking the postgraduate entrance examination again. From my architectural perspective, I look at this valley again. Recalling the road conditions when I came before, I realized what happened here.

This "ground" was not built half a person from the bottom of the valley, but was overhead in the air of the entire valley. I generally infer that the "ground" is at least 100 meters away from the real ground, and there is a huge hollow below.

Someone built a high-rise cement building in the covered valley under the "ground". The top of this cement building was at my feet, half a person tall from the "ground" I thought before. The water tank and the stone tray were all on the top of this cement building.

This is a huge hidden project. In my memory, there is only one project that can be compared with it, that is, the silo of the intercontinental missile. But I have also made such a judgment in my previous experience, and this is impossible.

I dare not enter because there is no lighting tool, so I can only wait until tomorrow morning. There is sun. Such a building must have an entrance to enter from the top, otherwise it would not be like this. Because this camouflage layer does not cover the top of the building. (It was later confirmed that my statement was wrong.)

But my inner shock suddenly couldn't calm down. If I guessed correctly, maybe the ground was equipped with slide rails. The disappeared road was on the hillside below this ground. The entire "ground" was guided by the slide rails and tilted downwards, which would reveal the dirt road, and cover up the dirt road.

The valley is not wide, and the mechanical design is not as complicated as the mechanical ones at the top of a basketball hall.

But where is this place? Coal mines, liberation trucks, human-shaped monsters. I have many ideas. Will these coal mines be dug out during their project, and they are not really producing coal, so there is no trace of the coal mine in Linzhong in the end. However, you must go in and see the traces tomorrow to understand.

I basically didn't fall asleep that night. On the one hand, I was afraid of what I had encountered before, and on the other hand, I was thinking about it, but I forced myself to rest. It was not safe to sleep here, and if I died of sleep, I might snore. I simply stopped sleeping, using hay and branches to make torches while waiting for dawn.

When it was dawn, the scenery around me became brighter and brighter. I found a flat place to make a bed, and made several traps around me that touched my fingers, and glared for a while.

I am really tired, but to be honest, my body is much better than before, especially during the time I came to Yinchuan, I slept very well every day, so after a while, my spirits recovered almost.

I didn't have anything to harm me, so I was killed by me? I felt that I touched it in my heart, and I came to the fault again and looked down.

With the light, my judgment was true. I couldn't see the bottom at all. I walked around the fault for a while, but I couldn't find the stairs downward.

It seems that this entrance should be on this roof.

Um.

My eyes rolled and I looked at the insect plate and the water tanks.

These things are abrupt here, but if they appear in a wilderness, at most others think there is a strange stone and some old water tanks here.

Will there be a hidden entrance to these things?
