As a human settlement, it is natural to be different from experimental facilities, not only because of their different functions, but also because of the different requirements for the people and the size of the site they want to occupy.

What's more, this is still on the moon.

Urban planning in beautiful areas of the earth should be particularly exquisite, let alone a desolate moon, which is a place that is even more barren than the desert on earth, and it is really hairy.

The previous scientific research base, which was mainly for scientists to conduct scientific research, was used to study the mysteries of the moon, and was an outpost for the official establishment of the lunar city and the construction of lunar immigration in the future.

The scientists, who will be resident for several months, have been carefully selected and have been tuned and trained for their physical characteristics, psychological problems, and so on.

But that's it, the arc group is also trying to make a lot of new tricks in this closed environment, what scenery windows, ergonomic design, entertainment room, bar and other relaxation equipment, and even built a set of research and ornamental in one of the "vegetable greenhouse", planted in which a large number of green vegetation is planted, which is used to relax the personnel in the base.

Although tourist flights were later opened, and a limited number of ordinary people were also introduced, at most, they stayed there for a few days at most, and the experience of a novelty was over.

Just like the Tiangong space station of the Arc Light Group, the permanent residents are some scientific researchers with very good psychological quality, ordinary people just come up to stay for a few days, experience a novelty and go back, and when they stay for a long time, they will definitely not be able to stand it.

Because these places are not designed for ordinary people to live in for a long time.

Tiangong space station, as well as the current lunar base, although these places have been built very spacious, and the design is more humane, I don't know how many times better than the space station before humans, and the lunar base is even more unprecedented, but they are not built for ordinary people after all.

To put it bluntly, it is a special facility, built for a small number of professionals.

Now it's the turn of ordinary people, and it's still a huge number of ordinary people, so there must be something different.

First of all, the place should be large and the sense of space should be sufficient, not as "narrow" as the experimental facility, and the ceiling of more than two meters high can be touched with a light jump.

So the arc group came up with this shell structure.

From the outside, this structure looks like a hemispherical hood that is fastened to the ground, providing enough space for its interior, and for ease of maintenance, it is actually a frame structure, which is then filled with hexagonal defensive armor plates, which are the outermost layer of defense of the "bubble".

It is also the outermost layer that is in direct contact with cosmic radiation.

In order to reduce the damage of cosmic radiation to the residents of the moon city to a limited extent, the arc group has coated a kind of mirror paint on the outermost layer, which has a high reflection effect on some cosmic radiation, and when these radiations come through, it will reflect a large part of it.

It is precisely because of this special paint that it will reflect the light when it is irradiated, making these covers on the surface of the moon look like bubbles from high altitudes, so it has the nickname "bubble".

In addition to this first layer of defense, this shield has several layers of structure, all of which are used to defend against different kinds of cosmic radiation, and they are also one of the main sources of resources and expenses.

After the filtration of these layers of defense, the cosmic radiation that penetrates in has been much less, at least ordinary people can live here, as long as they pay attention to taking some anti-radiation drugs every once in a while, there will be no major problems.

Therefore, in fact, the radiation problem is not a big problem for human beings, and even if there is, it is estimated that it will be a very long-term and slow effect.

This kind of equipment of the Arc Light Group is much better than the early space colonization behavior of human beings in many literary works, after all, those things are all based on the gradual progress of human science and technology, and various space technologies are not particularly mature fantasies, Dong Chen's side has a mature technology source, so he is not intimidated at all.

Other technologies similar to the simulation ecosystem, not to mention the black technology obtained by Dong Chen, can even be solved by the current earth, so it is not a problem.

In fact, the biggest impact on these space migrants is the gravity of the moon, which cannot be changed in the short term even if Dong Chen has black technology.

But fortunately, it can't solve the problems of the entire planet in the short term, but it is still possible to solve the problems of human beings themselves, although it is not possible to transform people into supermen, but it is enough to minimize this damage and impact.

Sometimes the flesh can be a real drag, but that's what humans are, aren't they?

With such a space, in fact, if other construction is carried out, it is basically similar to the earth, but there are some local restrictions.

In order to ensure the stability and practicability of the shell, the arc group does not plan to build too much single space at this stage, so the diameter of each bubble is between several hundred meters, and the height is also between tens of meters and hundreds of meters.

It is these large and small shell spaces that are connected together, and then the first phase of the third phase of the current Arc Group lunar program is formed.

In order to better simulate the earth's environment, the ceiling of the internal space of the shell is also covered with a display screen, which is equivalent to a super-large full-coverage "scenery window", Dong Chen The blue sky and white clouds they saw when they came in were exactly its function, and it also made the originally not very huge space suddenly appear more layered and not depressing.

It was it, coupled with some trees that were transported from the earth with blood, flowers and grass seeds that were born quickly, etc., that made Dong Chen and them shocked.

While they were watching the scenery, Xing Chenjia, who had just run out to play, also ran back again, and came up with a strange look and twisted Lian Ruyue's arm, and Lian Ruyue screamed in pain.

And Xing Chenjia, who had finished twisting the person, heard Lian Ru's howl, the strangeness on his face immediately disappeared, and he shouted happily, "Wow, these are all true, I can't believe that we are on the desolate moon, it's so beautiful." ”

Seeing this, Dong Chen next to him also laughed, pointed at Lian Ru and said, "See, this is the most direct way to verify the authenticity, don't you doubt it now?" ”

"I'm a special ......" Lian Ruyue, who came back to his senses, glared at Dong Chen while rubbing his arms, and then shouted to Xing Chenjia, "You have been touching the trees and flowers there for a long time, you don't know the truth yourself, you have to come back and twist me!" ”

"You come over to me, see if I don't kill you today!"

"I'm going to let you know why the flowers you just saw are so red, and I'm going to let the people here witness the first recorded human lunar conflict ever."

As he spoke, he rushed towards Xing Chenjia.

"Haha, brother, it's not that I underestimate you, on the earth I am more than 100 meters in more than ten seconds, here I am faster!"

"Hey, Xing Chenjia, you wait for me...... Hey, don't run away,! Look at the wall! ”

"Huh?"

"Ahh

"Ahh

And Dong Chen, who had just finished laughing next to him, laughed again, and then looked at a person holding a camera not far away and smiled, "I think starfish, the show is full of points." ”

"Especially the last shout, which successfully explains what it means to have multiple meanings."
