At the end of the visit, Su Zhe and his entourage came to the most core location of the second earth, the center of the central location.

This is the control center of the second earth, where you can see everything on the second earth, and can fully control the second earth.

A few people sat in the control center, looking at the screens in the control center, and those very primitive control buttons, and those who didn't know thought it was a control center built in the last century.

Seeing this scene, Fan Xiaoming sighed and said: "Such a control center is just in case, to be honest, this is the last guarantee, but the possibility of using it is not high, of course, such a control center is still needed, after all, it is not certain that there will be no accidents." "With the brain-computer, such a primitive control is really backward, but relatively, backwardness also represents stability.

As far as the brain-computer is concerned, there is great convenience in terms of control, but the same, the risk is also very large, but the original control is different, the convenience is a little worse, but its stability.

Si Wenbo nodded and said: "Yes, that's what we think, this is the last guarantee of the second earth, and it is also a kind of comfort in the heart. Zuo Dajun said excitedly: "There is no comparison, the brain computer is much more convenient, just like now, using these screens to see the second earth is not as good as the brain computer, the brain computer is too convenient." After Zuo Dajun finished speaking, the environment that several people saw changed.

To say that from the perspective of a third party, the environment has not changed, Su Zhe and the others sat in the control center, and the surrounding environment did not change at all.

However, the picture that Su Zhe and the others saw was different, what they saw was the combination of reality and virtuality, and what they saw was the superposition of the control center and the virtual picture.

The virtual screen shows the reality of the Second Earth, from the inside of the Second Earth to the outside of the Second Earth.

As far as the authority of Su Zhe and the others is concerned, everything can be seen. From the core of the Second Earth to the external situation of the Second Earth.

This time, Su Zhe and the others were under the control of Zuo Dajun and started to look at it from the outside of the Second Earth.

The second Earth is in the same orbit as Proxima B, and the distance from Proxima Centauri B is not very far, and in the orbit of the second Earth, there is Penglai Sky City.

It can be clearly seen in the picture that there are frequent personnel exchanges between the Second Earth and Penglai Space City, and these people are interested in each other, and they just want to see what the other party does not have.

Looking at these, Si Wenbo sighed and said: "I envy the Penglai Space City, which can have a population of 10 million, but there are still 100,000 people on our second earth, if we have 100,000 people, then the increase in population can be greatly improved," The usable area of Penglai Space City is not large, but the population is really large, a full 10 million, but the usable area of the second earth is large, and it is the same as the earth, but the result is that the population of the second earth is only 100,000.

There's really no comparison between the two. Zuo Dajun smiled and said, "Professor Si, you can appeal, let the people of Penglai Space City move to the second earth soon, anyway, now that you are together, it is very convenient to come." Si Wenbo smiled bitterly and said: "Actually, we have appealed and given a lot of benefits, but unfortunately no one can take a fancy to it, and I don't know what those people on the Penglai Space City think, anyway, no one came, but many people also gave an explanation, saying that the current second earth is not perfect enough, and when the second earth is completely perfected, they will consider it, I think they just say it casually, they can't take it seriously, as far as the current situation is concerned, they can only let people on the earth come." "The current second earth is not perfect, and at this point, the second earth is not as good as the Penglai space city.

It can be said that the ecology of the current Penglai Sky City is exactly the same as that of the earth, and what can be done on the earth can be done on the Penglai Space City, on the contrary, because the second earth has not yet been perfected, it cannot be done.

Xu Zhengping looked at Si Wenbo and explained: "Professor Si, don't think about it, your two projects are open for application at about the same time, and the fundamental concepts of choosing the two are completely different, so there are very few people who are willing to come to the second earth. Fan Xiaoming smiled and said: "That's the case, but it's hard to say about the next generation, as far as the current trend is concerned, children may be out of the care of their parents as early as possible, you know, the usable area of Penglai Space City is not much, and those children will leave Penglai Space City for sure." "Penglai Space City is so big, and the usable area is incomparable to that of the second earth.

You must know that the population on the Penglai Space City is now 10 million, and according to the first batch of statistics of the population increase plan, there are basically 100 children in a family, so that even if it is the first batch, it will be 500 million people.

It's not that Penglai Space City can't afford to support these people, but for the limited usable area of Penglai Space City, there are indeed so many people.

Naturally, most of these children are going to leave Penglai Space City. For this, those people in the Penglai Space City are all aware.

Looking at Si Wenbo's thoughtful appearance, Zuo Dajun reminded: "Professor Si, if you want me to say, in the next period of time, when the Penglai Space City arrives, you will let the second earth go, believe me, as long as it takes a few years, the children of the Penglai Space City will come to the second earth, think about it, this is a population of hundreds of millions, you can't miss it." Si Wenbo nodded again and again, and said: "Yes, yes, it should be like this, as far as the current situation is concerned, population is the most important, take the second earth as an example, one billion people is the bottom line, less is not good, anyway, the second earth is the same at this stage, it should follow Penglai Sky City, of course, in the next three years, the two have been arranged together." Xu Zhengping smiled and said: "That's right, in my opinion, as long as the second earth is perfected, it is more attractive than Penglai Space City, that's for sure." At this time, the picture in front of several people changed.

What you see is the exterior of the Second Earth, and on the outside, there are many huge engines and various equipment.

The engine powers the second earth, and the rest of the preparation has all sorts of different effects.

Seeing this, Zuo Dajun was excited, and said: "With these, the second earth can run away at any time, and you can get there if you think of it, unlike the earth, you can only stay in the solar system, stay in the inherent orbit, and let me say, if you transform the second earth a little, the second earth can become a big killer." "As far as the second earth and the earth are concerned, the survivability of the second earth is not a little stronger than that of the earth.

The earth itself is not fragile, but the earth's environment is quite fragile, and it is no exaggeration to say that whether it is the earth itself or the solar system, even if there are only inconspicuous changes, reflected in the earth's environment, it is a big change.

If the earth's environment changes, and the quantitative change reaches a qualitative change, the earth's environment will no longer be suitable for the survival of these creatures at present, and it will naturally be unsuitable for human survival.

Anyway, there will be no such situation on the second earth, simply put, how the external conditions of the second earth change, it will have little impact on the internal environment of the second earth.

Fan Xiaoming smiled and said: "It was originally a big killing weapon, you think that the death light and electromagnetic cannon on the surface are not set up, although it is worse than the death light and electromagnetic cannon equipped with the SS-defense system, but it is more than enough to deal with ordinary threats." At this moment, several beams of light flashed.

An asteroid 100,000 kilometers away from the second Earth was hit, the asteroid was a kilometer in diameter, but under the blow of several beams, it vaporized in an instant.

Looking at this scene, Si Wenbo said seriously: "Relatively speaking, the second earth is already a big killer, as for a more powerful attack power, that is not allowed, the purpose of these weapons equipped with the second earth is to defend, not to attack, so it is best to do this now." At this time, the picture in front of several people changed again.

On the surface of the Second Earth, there are several passages leading to the interior, through which the picture comes to the interior of the Second Earth.

Before, Su Zhe and the others went all the way north from Australia to the Huaxia Continent, and then went to the core of the second earth, and there were many places where several people did not go.

At this time, what is presented in the picture is a place that they have not been. The picture is constantly switching, there are oceans and continents, except for the Chinese mainland, which has a green, and the rest of the place is wasteland, and scattered buildings.

Looking at these, Zuo Dajun said with emotion: "This terrain and landform are exactly the same as the earth, to be honest, there is no difference between children who grow up in such an environment and children who grow up on the earth, that is, it is not perfect yet, if it is perfect, then there is no difference with the earth." Until now, he still felt that the person who proposed to replicate the earth in the first place was a man of God.

Not only the topography of the earth is copied, but even the place name is the copied earth, so that whether it is a child who grows up on the earth or a child who grows up on the second earth, they all have the same cognition, naturally, they have the same sense of identity.

Fan Xiaoming said with a smile: "It should be done, but it's also interesting to think about, just like the road names of various cities, in fact, they are all the same, as time goes by, the second earth will only become more and more, and I want to distinguish in the future, I know the code name in the front, otherwise it will really be where it is, speaking of which, where to live in the future, in fact, it is the same, there is a brain machine, there is a virtual universe, as long as it is within the scope of the virtual universe, the difference is not big, just like me, my flying castle has been built, Just waiting for the children to be born, and when the children are born, my wife and I will wander with the children. As he spoke, Fan Xiaoming waved his hand, and the picture in front of several people changed.

A magical flying castle appears in the frame. Zuo Dajun was a little yearning, and said: "Originally, I also had such an idea, but my wife disagreed, I envy this kind of life, I can fly around, I want to be there, in other words, there are many people who have such ideas now, and there are really not a few, just such a flying castle, and now it is being built intensively." As he spoke, a picture of the construction of the Flying Castle appeared in front of several people.

In the picture, there are a large number of construction machinery and engineering robots are busy, and there are not too many half-finished flying castles.

Xu Zhengping nodded and said: "Yes, there are many people who have chosen this kind of life, as long as it is within the coverage of the virtual universe, it is okay, such a life is unimaginable in the past, speaking of which, it has only been two years, and it has developed to the current scene, I dare not imagine, no, I also set a flying castle, and I plan to visit." Su Zhe smiled and said, "Yes! I'm going to walk around, and my wife and I have agreed that when the designed spaceship is built, we'll have seven months to walk around the solar system and its surroundings, and this is a good opportunity, and when the children are born, we don't think there will be much time. As he spoke, Su Zhe waved his hand, and what appeared in the picture was a billion spaceship.

Seeing this spaceship, Zuo Dajun was very surprised, and said: "What a big spaceship, the length of this spaceship is more than five thousand meters, it is really good to play on such a spaceship, I am really envious, I don't want to think about it, real people can't go, they can only use the way of humanoid bionic robots." Su Zhe nodded and said: "The length of this spaceship is six thousand meters, its facilities are complete, I have taken into account all kinds of conditions, and besides, my wife is pregnant with a child, so I still have to pay attention to it." "A long time ago, they agreed to play together after they got married.

Originally, he was going to wait for a while, after all, his wife was pregnant, but his wife Ning Qiaoqiao brought it up, saying that this time period was the most idle, and when the children were born, they would not have so much time.

Thinking of the current level of technology, he agreed. Fan Xiaoming looked at Su Zhe, thought for a while and asked, "You don't plan to travel for the two of you, do you?" Su Zhe smiled and said: "Otherwise, what we need is a two-person world, I accompany my wife to look around, such an opportunity is rare and must be cherished." "This is what they said, tourism is tourism, and it will not delay scientific research work.

Xu Zhengping smiled and said: "This is very good, have fun when the children are not yet born, after the children are born, there will be fewer opportunities like this, and you must consider the children in everything you do, so now is the best time." Si Wenbo nodded and said: "That's the case, after having a child, it feels completely different, take advantage of the opportunity to have fun now." Hearing Xu Zhengping and Si Wenbo say this, Su Zhe, Fan Xiaoming, and Zuo Dajun were a little surprised, but they all understood when they thought about it.

Several people continued to look at the Second Earth, while saying that the solar system and the places around the solar system were worth visiting.

You must know that from the landing on the moon to the present, the range of human activities has been very large. Not to mention the others, with the solar system as the center, the surrounding area of ten light years is covered by the virtual universe, and there are many places worth visiting.
