The first feeling when Lei Zhan saw this city was a strong sense of vicissitudes of time. Anyone who saw this city wanted to ask, who built it, what happened, and made this civilization disappear from the world?

This is a civilization built by mankind, a civilization that makes everyone worthy of pride. Even if today no longer has the prosperity of the past, its glory is eternal.

No matter what it encounters, the imagination it leaves to future generations and its role in the development of human civilization is as huge as its scale.

Everyone sighed that even the Long A and others of the Moon Star, judging from the construction scale and technology of this city, they are definitely no worse than their Moon Star.

Estein was stunned and kept muttering: "Oh my god, my god!"

Yes, the sky may not change for hundreds of millions of years, but human thoughts and perceptions of the world are always changing.

Just like the city in front of us, it completely confirms the issues of several major civilization systems that humans have experienced.

Moreover, what is even more incredible is that the technology in that era was definitely not worse than modern, or even higher than modern.

Through the blue light curtain, you can see that the tallest building in the middle of the city is as high as 2,700 meters through instrument calculations. With the existing technology on Earth, the height of this building can not reach at all.

This blue light curtain is emitted by an instrument on the roof of the building.

Lei Zhan tried to use perspective again to see the city, but he still couldn't pass through the light curtain.

Because the diameter of the city is too large, the United States can only develop the previous area. Therefore, if you want to see the entire city, you can only go to the tallest building or just do it.

Lei Zhan turned around and looked at Porter again, then asked with a smile: "How is it? Do you feel familiar?"

Porter said: "The city where the fantasy people live has many similarities to this city, but in terms of scale, it is not that big, look over there!"

As he said that, Potter pointed to a building similar to a temple under the tallest building and then continued: "This is the temple of the fantasy people. There is also a building exactly the same as it in the city where I live, but it is ridiculous. We still cannot know what this temple can bring to us? Or what do we believe in?"

Lei Zhan nodded to express his understanding. When a person's brain is developed to this level, many life problems will be thoroughly understood. The so-called beliefs and pursuits can no longer allow them to find the true meaning of life, and they can only understand it themselves.

However, Porter's words also confirmed Lei Zhan's speculation that this city was indeed a product of that era. However, from the outside, it was impossible to know more information. Now we have to find a way to enter.

Several experts brought by Estein had already started to work. They took the equipment out of the box, turned on the light energy generator to power the equipment. Everyone was working.

The sound of the generator seemed particularly loud in this space, and it also made it heard by other people who were digging out land on the edge of the city in another area. These American experts followed the sound to Lei Zhan. After the two sides met and introduced, these people became very interested in the equipment of Estein and others.

Can they not be interested? These devices are all things Lei Zhan collected from aliens. No one in the world has ever seen them except the people from the Dragon Blood Base.

From the perspective of human relationships, Lei Zhan can be seen, but from another perspective, these experts are Americans, and these technical equipment are top secret equipment of the Dragon Blood Base and cannot be seen.

So Lei Zhan asked Long A and the others to stop these people from getting close to these equipment. Long A sneered and said, "You idiots, continue to dig your land. Let's show you these equipment. You can't understand it. Don't affect our work. Leave quickly!"

These experts from the United States are geological experts, and the youngest ones are in their fifties. Seeing that Dragon A is so terrible, he can only retreat.

As long as you don’t look at the equipment, you can talk or something.

There are a total of hundreds of experts working underground. Basically, all experts are working for how to enter the city.

Because there is quicksand around, some construction workers also fix the wooden boards above the space at any time to ensure that the space they excavated will not collapse due to quicksand.

These experts have been working here for five years. They have been working here since they received orders from the country and have never left.

At first they were very resistant to the job because there were no offices, no bars, and not even a decent bed. All day long, except sand, this city that could be seen but not touched.

But now, even if they are asked to leave, they will not leave. Each of them vowed that they will never leave without opening the gates of the city.

But various experts and engineers have changed one after another, and many people have died because of the quicksand collapse. But so far, the only thing they have encountered is the base of the city, an unknown metal substance.

By scanning and analyzing the metal surface, they could not analyze what material it was. In the end, they could only speculate that it was non-Earth material.

There are still many things that have been discovered, but these engineers are absolutely impossible to tell Lei Zhan without York's approval.

Lei Zhan didn't expect them to say anything useful, so he asked them to continue working. After they all left, Porter, who had been observing, said to Lei Zhan again: "Mr. Lei, this light curtain is not to stop others from entering, but to protect the city from being buried by these sand!"

Lei Zhan smiled and said, "You have the same idea as me, or they are protecting some objects in the city. Otherwise, why would only this city be preserved and other cities disappear?"

When Lei Zhan was in the elevator, he thought of this question: sand can bury everything, why didn’t this city be buried?

If the city belongs to him, he would also find ways to stop the sand when it encounters desert erosion.

This brings up another topic, the origin of the desert.
