In the space ranch, five humanoid robots flew and hovered in the air, but in an instant, the five humanoid robots came to standby.

At the same time, Su Zhe. Fan Xiaoming, Xu Zhengping, Bao Qizheng, and Zuo Dajun appeared out of thin air in the space where the second earth of the virtual universe is located.

In front of the five of them was a huge sphere with many small points of light on its surface.

In addition to this huge sphere, the entire space is full of shining stars.

Zuo Dajun discerned the direction, pointed to the brightest star behind several people and said, "That's the sun, judging from these distances, the position we are now is estimated to be in the Ke Yin Bo belt."

Fan Xiaoming smiled, "Yes, yes, I am surprised that the army can still see this!"

"What's here, you can't see it casually." Zuo Dajun smiled and pointed to the light spots on the huge sphere and said, "Those are the light emitted by the Second Earth engine, judging from the color of these light spots, this is a simplified version of the heavy photon aerospace engine, we can see the light spots from such a distance, which shows that this simplified heavy photon aerospace engine is made of an unusually large one."

Obviously, the second earth relies on the power provided by these engines, and with these powers, the second earth can fly freely in the universe.

And he also knows that this simplified heavy photon aerospace engine can do very huge, and there is no problem at all with the power provided by the simplified heavy photon aerospace engine to accelerate the second earth.

According to the calculations of some do-gooders, as long as 100,000 of these simplified heavy-photon aerospace engines are installed on the earth, the earth can be pushed out of orbit, and the earth will fly out of the solar system, and the earth will fly freely in space.

"Dajun, this is all for you to see, it's really good, the simplified version of the heavy photon aerospace engine has been used very widely, from small probes to the second earth we see, so to speak, the simplified version of the heavy photon aerospace engine has replaced those engines in the past." Xu Zhengping said with a smile.

Zuo Dajun smiled, "This is too obvious, besides, except for the simplified version of the heavy photonic aerospace engine, other engines are not useful."

"Yes, that's right." Xu Zhengping said.

Fan Xiaoming smiled and explained: "The space we are in now simulates the solar system, the brightest star in the distance is the sun, and these spheres in front of us are the second earth, and its sphere diameter is the same as the earth, and the position of this second earth is in the Keyinbo belt, which flies around the sun."

This space in the virtual universe is actually specially opened up for the second earth, and the purpose is to verify the feasibility of the second earth.

"Huh! There's a lot going on on the surface of this sphere, the second Earth." Zuo Dajun said a little anxiously, "Let's go, let's take a closer look."

As soon as Zuo Dajun's words fell, a person suddenly appeared in front of the five people, and several people fixed their eyes to see that it was Professor Si Wenbo of Qing University.

After the warm greeting, Si Wenbo said with a smile on his face, "Guys, how come you have time to come here, are you here to visit the Second Earth?"

He knew it the moment Su Zhe and the five appeared.

Speaking of which, before the five people appeared, he knew that these five people had applied to visit the Second Earth, and there must be no problem for these people to come to visit.

Fan Xiaoming jokingly said, "If you don't come to visit Second Earth, let's come and see Professor Si...... Professor Si, your ambition is not small, and you have quietly created a big killer like the Second Earth, and I heard that your goal is to make the Second Earth cover the entire universe, and this goal is really ambitious."

Si Wenbo shook his head and said: "This is nothing, no matter how good the second earth is, we can't rely on you to come up with the technology, as far as the core device of the second earth, the controllable nuclear fusion device, I thought it would take a long time to achieve it, but I didn't expect that you would make a proton fusion device so quickly, this is simply the gospel of the second earth, to be honest, we considered using fission energy before, and finally found that it was not feasible, and the cold nuclear fusion technology that was very popular recently discovered was not used, in my opinion, The most suitable for the second Earth is the proton fusion device, not to mention

In addition, protons, that is, hydrogen, are the most abundant elements in the universe, and we don't have to worry about nuclear fuel at all."

Speaking of which, both cold fusion and fission have the same problem, that is, there are a lot of naturally occurring fuels, or there is no fuel at all.

It is still possible as a supplement, but it is not possible to use it as a primary energy source.

At the beginning, Qingda had an attitude towards the second earth, which was to slowly verify it, waiting for the maturity of related technologies, but I never expected that the key technologies would have results so quickly.

Fan Xiaoming smiled and said, "Judging by your excitement, you have great expectations for Second Earth, or you have great expectations for the proton fusion device."

Si Wenbo nodded repeatedly, "Of course, don't forget, many of us in Qingda have also participated in the design of the proton fusion device, and we still know how sure we are."

"That's!" Fan Xiaoming reminded, "Professor Si, we don't have much time, take us on a tour of the Second Earth, to be honest, our expectations for the Second Earth are very high."

Zuo Dajun hurriedly continued: "Yes, yes, I think the goal of Qingda can definitely be achieved, and the second earth can completely carry human civilization throughout the universe."

"With that said, let's go, I'll show you around." Si Wenbo smiled.

The six disappeared in an instant, and when they reappeared, they were already on the surface of the sphere, or the surface of the second earth.

Second, the surface of the earth is like glass.

The six of them stood up and watched a large, blue-glowing device not far away.

Before Zuo Dajun could ask, Si Wenbo had already explained.

"What we see in front of us is the largest simplified version of the heavy photon aerospace engine we can build, with a jet aperture of 10 kilometers.

On the second Earth there are 100,000 such simplified versions of heavy photonic aerospace engines.

Under normal circumstances, one-tenth of the engine operation can run in space with the second Earth.

Moreover, these are not simple engines, dead light with a diameter of 500 meters is nested inside these engines, plus related probes, the second earth is not only the second home of mankind, but also an armed fortress.

With the development of science and technology, it is really difficult to say what will happen in the future, and besides, whether there are other intelligent life in the universe, even if there is no such thing, we still have to prevent other celestial bodies in the universe."

"Understood, understood!" Zuo Dajun was a little excited, "This is still a simplified version of the heavy photon aerospace engine, if it is a genuine heavy photon aerospace engine, how powerful will it be with such a large volume."

At this time, Fan Xiaoming smiled awkwardly and did not speak.

Si Wenbo said bluntly: "The genuine version will not be much more powerful than the simplified version, the difference is its energy utilization rate, the genuine version is a hundred times that of the simplified version, which is still the most conservative estimate."

In the end, Si Wenbo looked at Su Zhe.

Su Zhe smiled and didn't speak, Zuo Dajun smiled awkwardly, and said, "The second earth is currently in rotation, and it stands to reason that we can't stand on its surface like this...... And this floor, which is made of special materials, doesn't look ordinary...... Besides, there is still a big difference between this second earth and the earth, this surface is all other equipment except for the engine, or the ground under our feet, unlike our earth's surface is inhabited."

Fan Xiaoming smiled and said, "That's because we are in an invincible state, you can try to remove the invincible state."

Before the words were finished, Zuo Dajun had already lifted the invincible state, and Zuo Dajun's body quickly expanded, cracked, and slowly floated up.

At the same moment, Zuo Dajun's expression was painful and he wanted to shout, but he couldn't say anything.

At that time, there were more and more places where Zuo Dajun's body was broken, and it began to bleed out from the rupture.

Suddenly, Zuo Dajun's expression became wooden.

It was also at this time that another left army suddenly appeared in front of several people.

A few people were not surprised, and looked at the still expanding and cracking Left Army together with the newly emerged Left Army.

In just a few minutes, the original Zuo Dajun was no longer in shape, and he could only see a human figure, and there was a lot of liquid floating in the space around it.

The liquid also solidified in a short period of time.

Zuo Dajun looked at his miserable face and twitched, and with a wave of his hand, the solidified liquid and body disappeared into the space.

"Dajun, you are really Meng, this feeling is not comfortable!" Fan Xiaoming said with a smile.

Several other people were also curious and looked at Zuo Dajun.

Zuo Dajun sighed and said, "This is much more uncomfortable than being in the ionization furnace, you don't know, the moment I lifted the invincible state, I could instantly feel my body swell, and I lost control of my body in an instant, and some only had endless pain, I couldn't stand it anymore and took the initiative to leave."

Compared to this, the ionizer is heaven.

In the ionization furnace, it was an instantaneous feeling, and then I didn't know anything.

It's not the same, it's going to be a "long" period of pain.

"This is quite outer space, and as far as our current body is concerned, it simulates the body of a real person, and you can know the consequences if you think about it." Bao Qizheng said, "Our human body is extremely fragile, so it is suitable for living in an environment like the earth, and other environments are not good."

Zuo Dajun smiled awkwardly, squatted down and knocked on the ground and said, "The material of this ground is not simple! It looks so similar to the material on the inner wall of the Sanmen Base Super Hadron Collider."

He was also negligent just now, thinking that it was a humanoid body that resembled a robot.

He didn't realize until the moment he lifted his invincibility.

Si Wenbo explained with a smile: "It's a similar material, this material can absorb electromagnetic waves and high-energy particles, to put it simply, this material can absorb energy and those tiny particles, and the reason for this is that it can be regarded as collecting energy and matter, and it can be regarded as a supplement to the second earth."

"I said, it's the same." Zuo Dajun smiled, "If only the surface of the Second Earth could be inhabited."

Hearing Zuo Dajun say this, Si Wenbo smiled awkwardly, "We can't solve the problem of gravity yet, if we solve the problem of gravity, we can build the second earth the same as our earth, we can only wait for later, when we figure out gravity, then we can also build a second earth one to one."

Fan Xiaoming smiled and said, "To solve the problem of gravity, we don't know when it will be, let's go into the interior of the second earth, you know, the interior of the second earth is where we humans live."

"Wait." Zuo Dajun said with a smile, "I know that the Second Earth can carry many, many people, but what if it is overpopulated, the space of the Second Earth is so large."

Si Wenbo smiled and said, "You should be asking about the expansion of the second earth, the second earth can add a celestial orbit, a circular celestial orbit, just like this."

At the end, Si Wenbo waved his hand at the sky, and saw many banded celestial bodies appear in the sky.

Zuo Dajun was very surprised and said, "This is what you are talking about, you can't see the whole picture!"

"We can see from a distance."

After Si Wenbo finished speaking, the six people disappeared at the same time, and when they reappeared, they were already in a very distant space.

The six of them watched as Second Earth was encased in a number of ring-shaped devices, which slowly rotated underneath.

"These ring-shaped devices are what you call the celestial orbits, and it's truly spectacular." Zuo Dajun looked surprised.

Si Wenbo nodded and said, "These celestial orbits can be operated alone."

"This ...... These celestial orbits look familiar, isn't this an enlarged version of the space farm, the No. 1 biosphere or something?" Zuo Dajun thought about it and said.

"Pretty much, indeed." Si Wenbo explained, "When we design the sky orbit, we refer to those, when we can't fully understand, we can only use this way to simulate gravity, this is the best scheme at present, to be honest, to thoroughly analyze gravity, or gravity, you need Lingzhou University of Technology, like us Qingda and Yanda and the like, it is not very likely."

」

Xu Zhengping smiled and said: "Professor Si, you don't have to be so modest, it's hard to say that side has finally completed the analysis of gravity and gravity, after all, it's not like before now, we won't have any difference in hardware, besides, your Qing University and Yan University are both old and strong schools, and now you each lead a special zone, and it is really uncertain who will kill the deer."

Si Wenbo nodded and said, "Yes, yes, but we don't have a genius like Su Zhe, in the second earth in front of us, if it weren't for the results made by Su Zhe, it would have been impossible to achieve it, and besides, we can have today's situation, Su Zhe has played a decisive role."

Although Su Zhe's contribution is not much publicized now, the relevant personnel are aware of it.

Su Zhe smiled embarrassedly, "Don't talk about this, let's go into the interior of the second earth and have a look, and after reading it, we will go back to see the artificial womb technology."

A few people smiled and nodded, and then a few disappeared in place.
