At this moment, at least half of the world's people are waiting in front of TV screens in their homes, bars, and squares to watch the Changying Group's experimental launch of the Earth Defense System through the space station and the Bifang satellite system. Ｘ

For ordinary people, this launch of Changying Group is like watching a realistic version of a Hollywood blockbuster, although it is only a fragment, it is a real thing, and things in outer space are not very ugly for scientists, but they are still very mysterious for ordinary people, at least this kind of big man-made thing is okay to see on the ground, and in space, it is unique.

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

This is also the geosynchronous orbit satellite theory of three satellites covering the Earth.

However, now these three sets of earth defense systems are aimed at the outside.

Yes, the muzzle.

The three Earth Defense Systems, when viewed from the big screen, look like a stout cannon on a base. And around this cannon, there are four small muzzles that resemble a phalanx. Of course, these muzzles are all adjustable in direction.

The caliber of the cannon is ten meters in diameter, and the caliber of the phalanx is fifteen centimeters in diameter, and the emphasis is different. He knew that the alien ships were several kilometers long, and even larger, and the small space fighters were not very large, a little larger than ordinary fighters. Therefore, the main muzzle is aimed at the starship, and the phalanx is aimed at the space fighter.

Without the support of the energy crystal, the traditional energy use mode cannot support such a large "cannon" at all!

Knowledgeable people know that these three "cannons" are a little shabby, but to be honest, with the current technology of Changying Group, it is not easy to make these three sets of finished products in a year.

Of course, in the traditional market field, Changying Group is still a dominant one, after all, it will take a long time for other companies to understand these technologies and form a mature production mechanism, so that their products can be tested by the market.

However, anyone with a discerning eye can see that the current near-monopoly situation of several pillar industries of Changying Group may not even take a year, and it will become a model of competing for heroes.

Many people can't figure this out, but for Changying Group, having a one-year buffer is enough.

Because of the various sub-groups of Changying Group, except for Shennong Group, which still produces food, the main task of other sub-groups has begun to slowly transform from the current main business to the development of space business, even Shennong Group is also studying how to develop agriculture in an environment similar to the earth.

The senior management of Changying Group knows very well that this period of transformation may be very hard and troublesome, and there may be no business for a long time, and they will have to rely on the old industry to support, and the old industrial space is also being squeezed step by step, but first, they believe that Lin Dong will not show them a wrong path, and secondly, the amazing development of Changying Group in recent years has accumulated a lot of funds.

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

It's a very dangerous distance.

Although this asteroid is not big, even if it is not blocked, it will directly enter the atmosphere, and it will be burned by atmospheric friction, and even if it falls to the surface of the earth, the remaining part can have a maximum of more than ten tons, but from an extraterrestrial point of view, this asteroid is still not small.

A cannon muzzle of the earth defense system was gradually adjusted, and then slowly shifted, after precise positioning, it was obvious on the big screen that white light began to emit under the base, and then you could see a flash of the muzzle, a white light suddenly shot out, and at this time, cruising in outer space to monitor the asteroid by the adjustment camera captured a very clear picture A white light accurately hit the asteroid that was rolling towards the earth, and then in less than a second, the white light disappeared, And the asteroid that originally looked huge was a small piece left at this time, and it was originally flying towards the earth at a speed of tens of thousands of kilometers per second, and it was not even a turtle speed at this time, it was rolling slowly, but it had lost its speed.

If there were no other external forces, it would take months for the asteroid to enter the Earth's gravitational sphere, and then be attracted to the Earth, and in the process of flying towards the Earth, it would be burned by atmospheric friction.

Later, on the big screen, the test launch process was played again, this time in slow motion, so that everyone could clearly see how the asteroid was burned by white light, leaving only the last bit of the core part.

Everyone who saw this scene was amazed 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 large cannon anywhere else on earth, there are probably not many telescopes of such a large caliber!

The successful launch of the defense system has raised the prestige of the Changying Group to a new height. The Changying Group had no intention of asking for credit from other countries, and after the defense system was successfully launched, they did not see any other actions, as if this matter was over.

However, the trees want to be quiet and the wind does not stop, they want to develop quietly, but some people do not want them to do so.

There was a sudden remark on the Internet: "If there is really an alien civilization that is much more advanced than the earth civilization to visit the earth, when they see the earth armed like a hedgehog, will they have a rebellious mentality?" Will this Earth Defense System cause misunderstanding for possible alien visitors? If their technological level is comparable to that of the earth, it is nothing, but if their technology is much more advanced than that of the earth, and they directly regard the humans on the earth as enemies after misunderstanding, then wouldn't the earth's civilization be wiped out because of the Changying Group's single-mindedness? ”

As soon as this set of remarks came out, it was immediately supported by many people!

Changying Group originally had a lot of potential enemies, and now someone suddenly jumped out to question him, although some people have been punished by Changying Group before and no longer speak out, but there are still many people who try to provoke the authority of Changying Group, and want to take the opportunity of suppressing Changying Group to make themselves fame and fortune in front of rich interests, what is the risk? r
