The main reason why helium-3 is rare on the earth is that the moon is a collector of solar wind particles, and in the 4 billion years since its formation, 200 million ~ 500 million tons of helium-3 particles have hit the soil at a depth of 10~50 meters on the surface of the moon.

Because the moon itself has no magnetic field, helium-3 particles can "camp" in the lunar soil.

In contrast, helium-3 particles on Earth slowly diffuse along the Earth's magnetic field lines under the action of the Earth's magnetic field, and are eventually "captured" by the atmosphere and disappear.

In addition, extracting 1 ton of helium-3 from lunar soil yields about 6,300 tons of hydrogen, 70 tons of nitrogen, and 1,600 tons of carbon. Like minerals from many major resource sources, these by-products are necessary to maintain a permanent base on the Moon.

In the past, these jobs were done by those professional space engineers, but these things were originally meant to be done by the general public in the future, after all, in the era of space immigration, these things still need to use professional space engineers, it would be a waste of resources, these people are all trained elites, and it is obviously the most cutting-edge planet development that is suitable for them.

Therefore, the Arc Group can also take advantage of the immigration experiment this time to let ordinary people also participate in the construction of space to see if this matching model is suitable.

Fortunately, in addition to those very professional jobs that must use professionals, many jobs are actually not very professional, or the arc group has made them less professional, even ordinary people can do it.

Just like the bulldozer that Dong Chen wants to drive, it is actually very intelligent, especially the electric drive, which is easy to drive, and you don't even need to learn, you can watch it for a while.

In fact, the arc group just wants ordinary people to have a job and keep them busy, otherwise once people are idle, they may not be able to do something for you.

Although there is strength, most of the work can be done by intelligent machinery, and then the productivity has been greatly improved, only some work that cannot be automated is still done by people, and most people are supported by very few people.

But in terms of Dong Chen's not very high ideological realm, why?

If you want to support yourself, then work on your own.

cough, just like Dong Chen himself is going to the mine now.

The self-driving vehicles are very close to the mine where they need to work, and a large part of it has been dug down, and it is a large pit with several large machines at work.

Oversized bucket wheels are digging down the mine, and the large forklifts load the ore into the trucks, which in turn transport the ore to the refinery, and their job is done.

And those uneven places due to mining and loading work are Dong Chen's job, and his job with No. 1 is to use bulldozers to level those places.

At first glance, this place is no different from some of the open pit mines on Earth, but the biggest difference is that it is not Earth.

The cockpit of all working equipment is a pressure sealed cabin, because human work needs it, and the giant machinery here is even bigger than the giant machinery on the earth, because the gravity here is low, so in fact, the same weight of ore will not cause harm to the equipment, you can build a bigger one, so the work efficiency is higher.

Not to mention that it goes down 6 times with a shovel, but it's a lot more.

Of course, this place is just an ordinary metal mining pit on the moon, and the helium-3 mine has been intelligently automated, so they are not needed.

There is a small rest base next to the mine, Dong Chen and they finished changing clothes inside and started working, with these 150 people joining on the moon, it is no surprise that they have entered a rapid development stage.

And Dong Chen's mixing on the moon is also quite smooth, or there are still few people on the moon, and it is far away from the earth, so everyone feels friendly when they see human beings naturally, just like seeing their fellow countrymen abroad.

So in this way, there are more opportunities for everyone to communicate, and they will get together from time to time, which makes everyone's relationship good.

And the arrival of these people has also enriched the lives of space engineers who came before them, but are not considered space immigrants.

It's also strange to say, obviously those space engineers came first, and there are quite a few of them, but they can't be regarded as space immigrants, they can only be counted as astronauts like those scientific researchers on the moon base.

Because they are all professional.

And in order to catch up with the construction schedule, their behavior on the moon really can't be called "life".

These newcomers are different, although some of them also go out to assist in the construction of the Moon City, and use it as a job to earn money to ensure their life on the moon, but this is only some of them.

Other people have planted flowers, farms, vegetables, restaurants, shops, bars, and even cinemas, which simultaneously released the latest blockbusters on the earth, so that the box office of the movie went directly out of the earth and rushed to the solar system.

In addition to the global box office composed of the North American box office, European box office, Asian box office, etc., the movie has an extra month box office.

For example, the North American box office is hundreds of millions of dollars, the Asian box office is hundreds of millions, and then the moon box office is 1,376 yuan, two cents and nine cents......

Ahem, there are discounts.

In this way, there are various jobs, diverse lives, and diverse entertainment, and this kind of life is called life.

After these people came, because of their various occupations, the lives of these space engineers were also enriched, so that they also had other places to go after work, and they would not just stay in the dormitory.

And because of their professionalism, although they were not the first immigrants and their lives were relatively boring, their wages were very high, and they were all wealthy.

With their joining, ahem, the development of the economy of the small circle here is better.

In the same way, the lives of these space engineers have become more colorful, and they are gradually no different from these immigrants, so it is natural that they have become the "second batch" of immigrants to the moon.

Even this process doesn't take more than two weeks.

After the successful operation of this small piece of Moon City, the tourist flights of the Moon will be opened again, this time tourists will no longer fly to the "unsuitable" Arc Group Lunar Scientific Research Base, but directly land at the interstellar airport of Lunar City, and start a new lunar journey in the "very suitable for playing" Moon City.

And Dong Du and Miss Yi Yi had to return to Earth to recuperate after spending two weeks on the moon due to physical reasons, because their bodies were really too weak!
