At this moment, at least half of the people in the world were waiting to watch the experimental launch of the Earth's defense system through the space station and Bifang satellite system at home, in front of the TV screens in the square. .

For ordinary people, the launch of Changying Group is like watching a real-life Hollywood blockbuster. Although it is just a piece, it is real. For scientists, things in outer space are no longer very ugly, but for ordinary people, they are still very mysterious. At least this kind of big man-made thing is OK on the ground, but in space, it is unique.

In theory, in the geosynchronous orbit, three defense systems with a spacing of 120 degrees can completely cover the earth and basically protect attacks from all directions.

This is also the theoretical three satellites covering the earth in the geosynchronous orbit satellites.

However, the muzzles of these three Earth defense systems are aimed at the outside.

Yes, muzzle.

The three sets of earth defense systems, from the large screen, look like a thick cannon on a base. There are four small muzzles similar to dense arrays around this cannon. Of course, these muzzles are all adjustable in the direction.

The caliber of the cannon is ten meters in diameter, and the diameter of the dense array is fifteen centimeters in diameter. The focus is different. After contacting the wreckage of alien UFOs, Lin Dong's mind has more information. He knew that alien starships are several kilometers long, and even larger. Small space fighters are not very large, but larger than ordinary fighters. Therefore, the main muzzle is for starships, while the dense array is for space fighters.

Without the energy crystal as support, the traditional energy usage model will not be able to support such a large "cannon" at all!

Those who know how to do know that these three "cannons" alone are a bit shabby, but to be honest, with the current technology of Changying Group, it is already very difficult to make these three sets of finished products in a year. In order to exchange the resources to make these finished products, Changying Group has made a lot of key technologies. During this year, many international companies are secretly studying the plans for exchange from Changying Group, and some even produce while researching. Now more than one company has produced finished products.

Of course, in the traditional market field, Changying Group is still the dominant one. After all, it will take a long process for other companies to understand these technologies thoroughly and form mature production mechanisms to allow products to undergo market testing.

However, anyone with a discerning eye can see that the current nearly monopoly situation of Changying Group's major pillar industries may not be needed for even a year, and it will become a model of heroes competing for the competition.

Many people can't figure this out, but for Changying Group, a year of buffering is enough.

Because the sub-groups of Changying Group, except for Shennong Group, still producing grain, the main tasks of other sub-groups have gradually transformed from their current main business to their space business. Even Shennong Group is studying how to develop agriculture in an environment similar to the earth.

The senior executives of Changying Group are very clear that the period of transformation may be very hard and troublesome. They may have no business for a long time and have to rely on old industries to support them. The space of old industries is also being squeezed step by step. But first, they believe that Lin Dong will not point them a wrong way. Second, the amazing development of Changying Group in recent years has accumulated a large amount of funds. Although it is not said that it can persist, it is no problem to persist for a few years.

Finally, the asteroid chosen as the target was less than 100,000 kilometers away from the Earth, and this distance was almost reaching the outer atmosphere of the Earth.

This is a very dangerous distance.

Although this asteroid is not big, even if it does not block it and enters the atmosphere directly, it will be rubbed and burned by the atmosphere. Even if it falls to the surface of the earth, the remaining part will be at most a dozen tons. However, outside the ground, this asteroid is still quite large.

A muzzle of the earth's defense system was gradually adjusted, and then slowly moved. After precise positioning, it was obvious on the large screen that white light began to emit from the base. Then you could see the muzzle flashing and a white light suddenly shot out. At this time, the adjustment camera was circling in outer space to monitor the asteroid. A white light accurately hit the asteroid that was rolling towards the earth. Then in less than a second, the white light disappeared. The asteroid that was originally looking at was a huge one, and it was originally flying towards the earth at a speed of tens of thousands of kilometers per second. At this time, it was not even considered a turtle speed. It was rolling slowly, but it had lost its speed.

If there is no other external force, this asteroid may have to take several months to enter the earth's gravitational circle, and then be attracted by the earth, and is burned by the friction and burnt by the atmosphere during its flight to the earth.

Then, the test launch process was played again on the big screen. This time it was slow motion, which allowed everyone to clearly see how the asteroid was burned by white light and only the last core part was left.

Everyone who saw this scene was surprised that Changying Group could create such a big guy. This is a big guy with a diameter of ten meters! Not to mention such a big cannon, there are probably not many telescopes with such a large caliber!

The successful launch of the defense system brought the reputation of the Changying Group to a new height again. The Changying Group did not intend to seek credit from all countries. After the successful launch of the defense system, they did not see any other actions, as if the matter had ended here.

However, trees want to be quiet but the wind does not stop. They want to develop quietly, but some people don't want them to do so.

This remark suddenly came out on the Internet: "If there are really many alien civilizations that are more advanced than the Earth civilization to visit the Earth, will they develop a rebellious mentality when they see the armed earth like a hedgehog? Will this earth defense system cause misunderstandings to possible alien visitors? If their technical level is comparable to that of the Earth, it is nothing, but if their technology is much more advanced than the Earth, and after the misunderstanding, they directly regard the humans on the Earth as enemies, wouldn't the Earth civilization be hit by the decisive actions of the Changying Group?"

As soon as this set of remarks came out, it immediately received support from many people!

Changying Group originally had many potential enemies, but now someone suddenly jumped out to question him. Although some people had been punished by Changying Group before and no longer spoke, many people still tried to provoke the authority of Changying Group and wanted to take advantage of the opportunity to suppress Changying Group to gain both fame and fortune in the face of generous benefits. What is the risk?
