With the continuous construction of the lunar base, the area of the base has gradually expanded. The construction of the lunar base www.biquge.info was limited to the Grand Canyon, which was surrounded by high mountain terrain, making the base look easy to defend and difficult to attack.

Inside the Grand Canyon is a rectangular flat land five kilometers long and two kilometers wide. All of the base's buildings are built on this rectangular flat land. Although the distance between the houses on the base is very separate, they are not readable. All of the buildings on the base are connected by circular passages, which are then combined to form a large human community, allowing everyone to travel through the entire community.

And it was only at this time that the lunar base was truly established, with all kinds of perfect functions. Humans can not only live and study on it, but also conduct scientific experiments on it, and even open factories on it to refine the rich resources on the moon.

More than three months have passed since Liu Hui landed on the moon, and the main building of the lunar base has almost been completed. The next thing to be carried out is the last link of this lunar base, that is, to install a gravity array under the entire lunar base, so that the gravity in the lunar base is the same as on the earth, and to minimize the inconvenience of the workers working and living in it to adapt to the environment.

Liu Hui took out two hundred and fifty-two seventh-level demonic beast crystal nuclei, buried these seventh-level demonic beast crystal nuclei in the ground according to the specific location calculated from the supercomputer, and completely fixed them, preventing them from moving at will. Then Liu Hui took out a large True Yuan Ball, and according to the requirements of the gravity formation, he controlled the True Yuan in the True Yuan Ball to flow into these Demon Beast crystal nuclei, and used the True Yuan to connect these seventh-level Demon Beast crystal nuclei together.

When the True Yuan flowed through all the two hundred and fifty-two Rank 7 Demonic Beast Crystal Nuclei, and finally formed a closed True Yuan Flow between these Demonic Beast Crystal Nuclei, the most amazing thing happened, gravity suddenly generated in the lunar base.

The employees of the Star Group, who had been living in the base for more than three months, suddenly felt that their bodies were heavy, and they immediately stood firmly on the ground. This sudden gravity made them unaccustomed to it.

Although the gravity formation has been activated, the magnitude of gravity is different from that of the earth. So Liu Hui and An Qi began to control the central control area of the gravity formation, debugging the size of gravity until the gravity in the lunar base became the same size as the earth.

At this point, the construction of the entire lunar base has come to an end for the time being, and the initial scheduled construction has been completed.

Liu Hui also spent four months on the moon, and he witnessed the birth of the lunar base from scratch and the process of gradually perfecting it. From now on, the Star Group can be regarded as truly stepping out of the earth and has an important foothold in space.

With the moon base as the biggest retreat, the Star Group will become more comfortable in dealing with the affairs of the earth in the future. After all, the Star Group has a way out, even if it can't stay on the earth anymore, the Star Group can relocate all the people to the moon base and continue its own development.

Just when Liu Hui was still immersed in the joy of successful construction, a warning suddenly came from the command and control center of the base, and asked Liu Hui to rush to the command and control center immediately.

Liu Hui was taken aback, it was the first time he had heard a warning from the command center after living on the moon for so long. When he hurried to the command center, he found that Angel had already rushed over, and she was learning about the specific situation.

"Angel, what the hell is going on? Why is the command center sounding a warning? Liu Hui asked.

An Qi pointed to a moving bright spot on the radar screen and said, "Liu Hui, you come here." This is an object detected by our aura wave radar, and this object is a large meteorite. Based on the current trajectory and speed of the meteorite, it will collide with the Moon five kilometers east of our lunar base in half an hour. ”

Liu Hui was shocked, the meteorite attack he was most worried about had finally arrived. Because the Moon has no atmosphere, the bare Moon is often attacked by meteorites in space, as can be seen from the craters on the Moon. But fortunately, they had long expected this to happen, so they specially prepared giant electromagnetic cannons and high-energy laser weapons to defend the security of the lunar base.

Although the lunar base was ready, when the meteorite really came, Liu Hui's heart was still a little nervous. Whether the defenses of the moon base will work or not will soon be known.

"How big is this meteorite?" Liu Hui asked.

"According to the data monitored by our aura fluctuation radar, the shape of this meteorite is oblong, the longest length reaches five hundred meters, and the total weight exceeds one million tons. If it did hit five kilometers away from our base, the energy of the impact would be equivalent to the energy of 5,000 Hiroshima atomic bombs. At that time, from the impact site, a radius of 50 kilometers will be affected, and our lunar base will be completely destroyed. Angel said.

Next, Angel mobilized the computer screen and displayed the flight image of this large meteorite on the big screen next to her.

Liu Hui saw the large meteorite that was still flying fast in space, and knew the serious consequences if it collided with the moon, so he immediately said: "So what are we waiting for? Start our electromagnetic cannon now! Crush this meteorite into space. ”

After receiving Liu Hui's order, the weapon control personnel immediately controlled the computer and charged the huge electromagnetic cannon. Then the barrels of the twenty electromagnetic cannons in the defense system began to turn, pointing diagonally in the direction of the meteorite flying in space.

Then the electromagnetic cannon began to fire, and a series of shells shot towards the meteorite that was still in space, and twenty fire dragons appeared in the sky in an instant, and they flew towards the meteorite.

Not only is the gravitational attraction on the moon small, but there is also no air, so the electromagnetic cannon of the lunar base really exerts its strongest combat effectiveness in such an environment. The electromagnetic cannon shells fired from the electromagnetic cannon can actually directly attack meteorites in space.

Liu Hui and An Qi looked at the meteorite on the screen with attention, and suddenly, a cannonball hit the meteorite, and the surface of the meteorite exploded violently. More shells then hit the meteorite, and after a series of violent explosions, the meteorite, which was still in space, was blown to pieces. Some of the debris then continued to fly towards the lunar base, while the rest of the debris re-entered into space and became a new meteorite wandering in space.

The electromagnetic cannon shells used in the lunar base are filled with super **, so its explosive power is very powerful, and the two hundred shells fired by twenty electromagnetic cannons are enough to smash the meteorite in space. Although Liu Hui has no intention of using this super ** on the earth, this does not prevent him from using this super ** in the defense of the lunar base.

I saw that the large meteorite was shattered, and more meteorite fragments continued to fly in the direction of the base. The base's aura fluctuation radar immediately locked onto the meteorite fragments, and the laser weapons arranged around the base began to charge. Then, under the control of the aura fluctuation radar, they each aimed at their own targets. In the blink of an eye, 300 high-energy lasers were launched, and the 300 meteorite fragments flying in front of it were completely knocked away and blown into powder, which could no longer pose any threat to the base.

In this way, 300 laser weapons were continuously launched, completely shattering those meteorite fragments. A minute later, 3,000 laser weapons had fired 3,000 lasers, destroying countless meteorite fragments. At this time, on the aura fluctuation radar, there were no meteorite fragments visible.

Liu Hui saw the powerful defense force of the moon base throughout the whole process, and the weapons of the moon base only took less than five minutes to destroy the meteorites that came from space, and even the fragments of the meteorites could not get close to the base, completely protecting the safety of the base, and he was very satisfied with this.

However, Liu Hui still felt a little uneasy, and he planned to install another 200 electromagnetic cannons and 400 laser weapons around the lunar base. With the protection of these 400 electromagnetic cannons and 800 laser weapons, the lunar base will truly become impregnable.

Solving the attack of the meteorite in space, Anqi and Liu Hui breathed a sigh of relief at the same time, so Anqi talked to Liu Hui about one more thing.

"Liu Hui, the energy we use in this base is still the energy in the high-grade energy stones, but for the long-term development of our Star Group, I don't plan to continue to use that kind of high-grade energy stones in the moon base." Angel said.

"Oh? If you don't use high-grade power stones, then what are you going to use as energy in the base? You must know that the energy requirements of the lunar base are also very huge. Liu Hui asked curiously.

"I'm going to use fusion power generation technology as an energy core in the moon base." Angel said.

"Nuclear fusion power generation? I know about this technology, but didn't you say that this technology still has some flaws and cannot be officially put into commercial operation? Liu Hui asked.

"It was true that our fusion technology had some flaws before, but in the past four months, we have been working on this technology. After our continuous experimentation and improvement, we have finally made up for the shortcomings of nuclear fusion technology, and surpassed a perfect nuclear fusion technology, so now we are able to put nuclear fusion technology into practical use. Angel said proudly.

Liu Hui was overjoyed when he heard that the Star Science Research Institute had finally come up with a nuclear fusion technology that could be used for practical purposes. Although Star Group uses deep-sea pressure to generate electricity on the earth, it has completely solved the energy problem required for the company's development.

However, in the future of interstellar travel or Martian migration, large interstellar transport ships will need to be used. In space, there is no deep-sea pressure to generate electricity for these spacecraft, so where does their energy come from? Although they could continue to use the huge energy contained in the high-grade energy stones, there was always a hidden danger in Liu Hui's heart.

Although the current Alexander and Liu Hui are of the same mind, they are desperately collecting Warcraft crystal nuclei for Liu Hui, so that the Star Group has stored hundreds of millions of billions of Warcraft crystal nuclei of various levels. But this does not mean that Alexander and Liu Hui have always been of the same mind.

One day in the future, if Alexander discovers the big secret contained in the Warcraft crystal nucleus, he feels that he has suffered a loss, and he is no longer willing to trade with Liu Hui. So the Star Group will completely lose the source of the Warcraft crystal nucleus, and what will the Star Group use to develop at that time, and how far can it go in this vast starry sky?

So when Liu Hui knew that the Star Group had mastered the nuclear fusion technology, he was truly relieved. Nuclear fusion technology refers to the process of fusing two lighter atomic nuclei into one heavier nucleus and releasing energy, this reaction has been going on on the sun for 5 billion years, so nuclear fusion reactors are also called "artificial suns". The nuclear fusion process will produce a large amount of energy, and in the fusion process, there will be no long-term and high-level nuclear radiation pollution caused by nuclear fission, no nuclear waste, and certainly no greenhouse gases, it will basically not pollute the environment.

The most important thing is that the raw material for nuclear fusion, helium-3, is very large on the moon. After calculations by the Academy of Star Science, they found that the helium-3 content on the moon reached as much as 715,000 tons, and you must know that one ton of helium-3 can generate electricity enough for all mankind to use for a year. So if helium-3 on the moon were collected to generate electricity, it would be enough to use the Star Group for more than a million years.

In addition, the material that can be used for nuclear fusion power generation is not only helium-3, but also deuterium contained in the earth's seawater, and can also be used for nuclear fusion power generation. You must know that the entire earth's seawater contains a total of 45 trillion tons of deuterium, and if all these deuterium are used for nuclear fusion power generation, it will be enough for tens of billions of years of human use on the earth.

Star Group has collected more than 100,000 tons of deuterium from seawater in the process of desalination, and if these deuterium are used for nuclear fusion power generation, it will also meet the needs of Star Group for more than 1,000 years.

The size of the fusion reactor is small enough to be installed in the starship as an energy core, which will provide enough energy for the spacecraft to fly over long distances. In the future, whether it is to carry out Martian immigration or further explore the mysteries of the universe, there will no longer be the problem of energy core.

That's why Angel is so proud after creating a practical nuclear fusion technology. After all, her technology has completely solved the energy problem encountered in the process of human development, at least human beings will not start a life-and-death war for energy in the future.

Liu Hui also knew the potential value of this nuclear fusion technology, and he was very happy in his heart, and he was more and more satisfied with taking him to see Anqi.

After the Star Group has this technology, even if Liu Hui suddenly loses the help of the plane trader, he will not have too much to worry about. Because the Star Group already has the ability to conquer the starry sky with this nuclear fusion technology.

So Liu Hui asked, "Anqi, now that your nuclear fusion technology is mature, when are you going to build the first nuclear fusion reactor?" ”

Angel said: "I have asked the scientific research institute on the "Star City" to build a nuclear fusion reactor, and it is not large in size, which is very suitable for interstellar transportation. Now as long as the fusion reactor is transported to the lunar base, and we inject deuterium fuel or helium-3 fuel into the nuclear fusion reactor, the nuclear fusion reactor can be started, and then we can provide an endless supply of energy for the lunar base. ”

Liu Hui asked, "Can a nuclear fusion reactor provide enough energy for such a huge lunar base?" ”

Angel said: "Naturally, this nuclear fusion reactor that we built for the first time has a power generation capacity of 100 billion kilowatt-hours of electricity per year. This huge amount of electrical energy can not only meet the needs of life and work in the base, but also use this electrical energy to serve us to refine the rich resources on the moon. ”

Liu Hui said with a smile: "This means that once we finish the construction of this lunar base, we will be able to immediately develop and use the rich resources on the moon to continue to expand our lunar base, and even provide rare mineral resources to the "Star City", is that true?" ”

An Qi smiled: "Yes, once the moon base is equipped with a nuclear fusion reactor, then except for some daily necessities, there is basically no need for the "Star City" to provide anything here. Because with the abundant resources on the moon, it can be allowed to grow and develop. It is important to know that the moon rocks contain all the elements and about 60 kinds of minerals on the earth, and 6 of them are still not found on the earth. The moon is also rich in precious resources such as iron ore, titanium ore, uranium ore, and rare earths. These resources can not only contribute to the development of the lunar base, but can even provide a large number of rare materials for the development of the "Star City". ”

Once the construction of the lunar base is completed, it will begin to exploit and utilize the rich resources on the moon, which is something that was determined when the lunar base plan was established. However, when Liu Hui heard the news, he was still excited.

After all, for so many years, human beings have been using the resources on the earth, and the plundering of nature for such a long time has caused the depletion of resources on the earth. Now after the Star Group rushed out of the earth, it found that the resources of the entire universe were so abundant, as long as they were industrious enough, they would get a huge amount of resources for development, and there was no need for the earthlings to fight for life and death for those limited resources on the earth.

Star Group is one step ahead of the world, enters the starry sky in advance, has huge resources on the moon, solves the bottleneck encountered in development, and even has a large surplus. However, Liu Hui does not plan to make these resources available to humans on the earth for free. All he cares about is whether the people on his "starry city" are living well or not, because those people are the people of the ideal world he is building. As for the other countries in the world who want to obtain the resources on the moon, then ask them to come up with the corresponding resources in exchange, Liu Hui will definitely not be a bad person and help them for free.

So after Liu Hui discussed with An Qi the development ideas of the lunar base for a period of time, he was ready to return to Earth on an interstellar transport spacecraft. After all, he has been away from Earth for four months, although he has absolute control over the entire Star Group through convenient aura fluctuation communication, he knows every move of the Star Group well, and remotely controls the development direction of the Star Group. But now the outside world has begun to have some suspicions about the abnormal situation of Liu Hui, the city lord of the "Starry Sky City", who has not shown up for four months, and some countries in the world have begun to use this to make a big fuss, so in order not to cause greater trouble, Liu Hui must immediately rush back to the earth, make a high-profile appearance in front of the world, and smash other people's conspiracy.

And because Anqi wants to sit in command in the moon base, he can only stay on the moon and cannot return to Earth for the time being.

An Qi was very reluctant to let Liu Hui leave, and in the past four months, she monopolized Liu Hui alone, which made her heart full of sweetness. But now Liu Hui is going to leave her and return to the earth, but there is no way to do it, because the Star Group is still inseparable from Liu Hui's leadership.

So the night before Liu Hui left, they were crazy in love in the room, and vented all their thoughts about each other for a period of time that night, so that when it came to the next morning, Liu Hui actually felt a long-lost feeling of backache after getting up, which he had never encountered since injecting the body evolution fluid.

This morning, when Liu Hui was about to leave the lunar base on an interstellar transport spacecraft, an alarm sounded from inside the command center. Liu Hui was surprised and hurriedly rushed to the command center, only to find that the entire command center was solemn, and everyone had a nervous look on their faces.

"What's going on again? Why do you have such expressions? Liu Hui asked.

An Qi pointed to the computer screen and said, "Liu Hui, you come here." ”

Liu Hui looked over and found that there was a bright spot on the screen that kept flashing, and he asked, "What's wrong?" Is there another meteorite? ”

Angel shook her head and said, "This thing is not a meteorite. She then zoomed in on the flashing highlight on the screen, revealing it for what it was.

"Huh...... This is not a meteorite, this is an artificial satellite? What country made a satellite in the hell? How did it appear in lunar orbit? After Liu Hui saw clearly what the bright spot was, he asked An Qi in surprise.
