After turning on the clairvoyance ability, he felt even more frightened, as he could clearly see that outside the elevator was an even larger space, and in the center of this space was a luminous object of unknown origin. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Teacher, what's the place below the experimental center, and can our current human technology reach such a deep place?"

Elder Zhang did not answer Li Yi's rhetorical question directly, and pretended to be mysterious: "You will be able to know soon!"

The elevator continued to run for several minutes, changing from time to time in parallel movement and descent, and when it finally arrived at its destination, when Li Yi left the elevator behind Elder Zhang, he found that the elevator had stopped at a depth of ten kilometers underground.

Facing the huge underground space in front of him, Li Yi was completely shocked, to be precise, this is a new world, where there are countless large and small buildings, except for a few buildings built on underground mountains, most of them are built on stepped stone walls.

Li Yi roughly estimated that at least one million people are engaged in various jobs here, among which all kinds of large construction machinery, and even rare construction machinery that can fly can be seen everywhere here, without exception, these construction machinery are all robots that tell automation.

"Child, isn't everything here scaring you, this is the underground world that your ancestors accidentally discovered, not only our country, the United States, Russia, these powerful countries have built large-scale underground cities in their respective regions. This is Dragon City, the largest underground city in China!"

"According to some scientific research, some human scientists believe that human beings do not come from the earth itself, but aliens, or exiled races, migrating to the earth because of the destruction of their own world, and so on, but there is a theory that we humans come from the underground world, and you see this underground space in front of you, which is believed to be all over the world, and it is still a very coherent passage!"

"Teacher, is this possible?" Li Yi was shocked by the underground world in front of him, so he interrupted Elder Zhang's words, and Elder Zhang's words didn't care about this:

"According to the current research and development of underground space science, scientists in the underground world of various countries have repeatedly argued that this completely coherent underground passage of various countries exists, but at present, many places have collapsed due to earthquakes, and there is also a saying that we have not found the correct passage. ”

The elder said, pointing to a very large airport not far from his feet, and said, "Have you seen this airport? The airport you saw in the scientific research center above is to transport supplies from the outside world on the one hand, and to transport materials here by plane. ”

"At present, the resources of this underground world we have arrived are basically self-sufficient, and only some resources that we cannot replenish here are sent here from the outside world. ”

Li Yi didn't know how to describe his mood at the moment, and he didn't know what he should look at or think, so he blindly followed the teacher, and when he walked in front of a skyscraper-like building, he suddenly asked:

"Teacher, is it all your responsibility here?"

"Of course not, the teacher is only in charge of the Longwei Secret Research Center above, which is under the management of the Longcheng Scientific Research Committee, and this committee is directly responsible to the top head of the country. ”

"So what is the significance of building this underground city of Dragon City for our people?"

Li Yi's question was obviously beyond Zhanglao's expectations, but soon Zhanglao still gave Li Yi a satisfactory answer: "Boy, you also know that the living environment on the ground is getting worse and worse, in order to allow the people to live a better life, the country currently has two ideas, one is to build an undersea city after foreign countries, and the other is to build an underground city." ”

"Originally, the construction of undersea cities had the upper hand, but with the discovery of some super-large underground caverns, and the discovery of the underground passage that can connect to the whole world, the construction of underground cities gradually gained the upper hand. ”

"Especially when building a city underground, you don't have to have a lot of restrictions in order to build a tight and safe protective cover, but this is limited to finding a huge space like the one in front of us, where the crustal structure is very stable, and with all kinds of safety measures, even if there is a big earthquake, there will be no problems here!"

Li Yi followed Elder Zhang's explanation to the entrance of the skyscraper, and after entering, he found that the building was built along a stepped crustal structure.

"The huge underground space we are currently in is one of the few safe areas in the seismic zone, and according to the scientists of the Scientific Committee, it can even accommodate hundreds of millions of people!"

"A recent design report pointed out that if the structure here continues to be stable, at our current pace of construction and technological development, if we build a super-massive complex like a beehive, this and the five other huge stable underground spaces we have found will even be able to accommodate all of our countrymen!"

"Ahh

When Li Yi heard this, his brain completely crashed, and this information contained too much content, far beyond his ability to bear.

"Of course, the construction has only been preliminarily completed here, and there is still a lot of work to be done, and it is also the location of various cutting-edge scientific research institutions in our country!"

Li Yi followed the teacher to the top of the skyscraper, where there was a narrow passage that could barely accommodate three people passing side by side, and nearly half of the space was three very thick side-by-side pipelines.

"Boy, do you see what's in front of you?"

Li Yi has been following Elder Zhang in ignorance, and only came back to the cliff-like place in front of him.

"Teacher, what's that?"

On the edge of the cliff where Li Yi stood, three kilometers away, there was a huge luminous body with a diameter of tens of kilometers, this luminous body was mainly red, mixed with yellow and purple, the brightness of the luminous body was not dazzling, and the temperature was like standing outside in the sun in summer.

"Our scientists haven't figured out exactly what it is, but all of our Dragon City is powered by it!"

At this time, Li Yi saw that on the huge cave stone walls around the huge luminous body, there were solar panel-like things all over the side near him, and the three giant pipelines were all cables.

"It's an unsolved mystery we've discovered in the underworld, and it takes a lot of scientific research to figure it out. ”
