"Report! Suspected pterosaur traces found on asteroid 173356!"

"Fleet Seven is dispatched!"

"Yes!"

The next moment, the warriors who were still laughing and joking immediately became serious, and each of them looked tense. They lined up neatly and left the base and entered their respective battleships.

The actions are meticulous and there are no mistakes even when measured by the most stringent operating regulations. The dialogue was carried out exactly as prescribed, with a clear tone and no unnecessary nonsense.

A total of 16 battleships of the Seventh Fleet set off immediately. With the cooperation of the automated combat system and unmanned warships, excluding the traveling time, it took only seven hours to annihilate a total of 6 pterosaurs lurking on the asteroid.

The fleet returned home. Even after leaving the battleship and entering the base, the soldiers still looked serious and unsmiling, and the team was neatly lined up without any dispersion.

But once they crossed the horizontal line of the rest area, the originally neat team immediately dispersed, and loud noises immediately emerged.

"Damn, what a pleasure! Did you see, I killed two of them with one missile?"

"Don't talk nonsense. Is that your own fault? Can you find the exact coordinates without me providing information?"

"But pull it down. If we hadn't surrounded and squeezed the pterosaur space, would you have found a chance?"

"The captain is here!"

I don't know who shouted, and the next moment, the noisy warriors immediately stood at attention, their bodies as straight as a benchmark.

The majestic captain came over and nodded with satisfaction: "Well, good job."

The captain left and the soldiers scattered again.

"Let's go, let's eat."

……

With the blessing of the entire war system, this incoming group of pterosaurs seems to have truly become people's prey.

There are many cases where the minority defeats the majority and the weak defeats the strong. In fact, the people on the planet have not felt much of the atmosphere of war. In less than five years, the human government has announced the end of the first phase of the campaign.

This means that most of the pterosaurs have been wiped out, and the number of pterosaurs has been reduced to less than 10% of the total, and most of them are lurking.

What is needed in the follow-up is to search bit by bit and eliminate them bit by bit.

Human civilization will use tens of millions or even hundreds of millions of detectors and unmanned warships to thoroughly and comprehensively search every corner of the solar system, search out every hidden pterosaur, and annihilate them, completely eliminating all threats to mankind. Spaceship threat.

This is a very long process that will take at least several decades, so there is no need to rush it.

At this moment, the three major civilization envoys were filled with bitterness.

I really didn't expect that humans could deal with the pterosaur swarm so easily, and the planet itself was not even threatened at all, and the strength of civilization was almost undamaged.

On the other hand, our own civilization has suffered heavy losses...

The Phix Civilization and the Motan Civilization are still struggling to hold on, and there is no glimmer of victory yet. The Yuanshan Civilization has already taken advantage, but the advantage is not big enough. A comprehensive counterattack will take time.

As a result, the balance of civilization strength is unbalanced, and it is still unknown what changes will occur in the Yuanshan Star Territory in the future.

"The galaxy is so vast, it is not easy to completely search and destroy pterosaurs. I hope this process can delay the progress of human civilization..."

With this expectation, the three major civilization messengers began to continue to observe human civilization.

But something even more unexpected happened.

"What? Humanity mobilized 10 million unmanned warships and 50,000 manned warships, mobilized a billion reconnaissance satellites, 20 million interstellar forts and interstellar missile bases, and surrounded the entire asteroid belt?"

Facing this news, the three major civilization envoys widened their eyes at the same time.

What a joke!

The asteroid belt in the solar system is relatively small, but it is also about 10 billion kilometers in length, tens of millions of kilometers in width and thickness, and contains tens of millions of various stars!

Isn't a search and suppression under normal circumstances a search bit by bit?

Now, you humans have directly surrounded the asteroid?

You are not searching and suppressing, but pulling out nets to catch fish, right?

It's still the kind of thing where you spread the net on all sides, leaving no dead ends, and catch everything in one go.

This kind of industrial strength... can this kind of industrial strength really be achieved by a second-level civilization? Is human civilization really a second-level civilization?

They won't quietly become a level three civilization, right?

The search for the asteroid belt lasted about two years. Afterwards, the human government announced that a total of about 800 million pterosaurs had been annihilated in this battle, and the asteroid belt had been cleared.

After that, a sufficient number of fixed observation bases and combat forces will be left to ensure that no pterosaurs can break into the asteroid belt again, and the search and suppression of the planetary rings, Kuiper belt, and interplanetary space will be started simultaneously.

The search and suppression methods of human civilization are simple and crude, without even any technical content.

A large number of warships, unmanned warships, detectors, etc. were thrown into space for free, forming a large net that sifted through the interstellar space bit by bit.

Humans simply ignored the whereabouts of the pterosaurs, did not speculate on where they might be hiding, did not calculate where the key spatial nodes were, and did not pay attention to the pterosaurs' conscious harassment and deception based on their combat instincts.

Human beings just follow their own plans and screen everything without leaving any blind spots.

Any conspiracy is useless in this way. No matter how strong your concealment is, it can only be established if the observation density is not enough. I'm just placing a detector every tens of thousands of kilometers right now. How can you stay hidden at such a close distance?

Just dream.

Eventually, humans pushed the search line beyond the Kuiper Belt.

Further outside, there is the vast ecliptic discrete disk and Oort cloud area, in which there may still be a large number of pterosaurs hidden.

Han Yang didn't have a good solution for this part of the area. After all, this place is too vast.

All Han Yang could do was to continue searching and clearing out. It may take hundreds or thousands of years to complete the task of finally wiping out the pterosaurs.

During this period, any spacecraft leaving the Kuiper Belt will be escorted and protected.

The early warning within the solar system has been lifted, and normal civil navigation has even resumed.

In a sense, this pterosaur crisis has been passed for human civilization.

Han Yang reviewed the entire process.

This is the first time that humanity has suffered a civilization-level crisis since becoming number one in the Yuanshan Star Territory. Reviewing the process of this matter is of great significance, and will help Han Yang truly understand his current combat power, as well as the comprehensive strength of human civilization.

After careful review, Han Yang finally came to a conclusion.

"There are two key points for me to be able to solve this battle so easily. The first is naturally my computing power and the engineering capabilities brought by the computing power. Needless to say.

Second, it is the great improvement in ‘quality’ brought about by the advancement of science and technology.

Detection satellites have a wider detection range, higher accuracy and more sensitivity. The electromagnetic gun has a higher rate of fire, faster projectile speed, more accurate shooting, stronger armor protection, and so on.

The convergence of countless small improvements brings about a huge leap in the overall strength of civilization.

Taken together, the combat power of human civilization has surpassed that of the other three combined civilizations. No, it is at least twice the combined combat power of the other three civilizations.

However, it is speculated that even so, my combat power is still far from that of a true third-level civilization. Quantity cannot make up for this.

So... now that this matter has been resolved, I should go all out to attack the third-level civilization. "

Han Yang made up his mind.

At this moment, as human civilization first solved the pterosaur crisis, the Yuanshan Alliance, which had been communicating frequently, became quiet.

Han Yang didn't think about supporting other civilizations. The three major civilizations that had called out the loudest before and strongly requested the assistance of human civilization also began to fall silent.

Han Yang knew the reason for this change very well.

They dare not let the human fleet go to help.

After all, after this crisis, the imbalance in the combat power of the four major civilizations has become a reality. Under such circumstances, as the most powerful human civilization with the smallest loss of combat power...will it take advantage of this disaster to destroy other civilizations?

The direct benefits are not great. But from the perspective of geosecurity, the long-term benefits are there, and they are not small. Moreover, the other three civilizations have been seriously damaged in this crisis, and destroying them is the best opportunity.

In this case, which civilization would dare to let the support fleet of human civilization come over?

When the human fleet turns its guns on itself, the fun will be great.

Han Yang certainly had no intention of taking advantage of others' danger. The reason is also very simple, it is not necessary.

Geosecurity? Am I worried about you threatening me in the future? What a joke.

If other civilizations ask for help from humans at this moment, Han Yang is really willing to go and help.

The reason is also very simple. There are certain benefits to human civilization.

The first is to avoid the risk of subsequent pterosaurs returning to the solar system, and the second is to enhance the pride and cohesion of civilization, and to establish the first position of human civilization in the Yuanshan star field.

To put it simply, it means taking in a younger brother.

If the other three civilizations can be determined to become human beings' younger brothers, then it will obviously contain huge benefits.

Not to mention the rest, a single technological exchange is enough for mankind to reap huge benefits.

Even if human civilization ranks first in technological strength at the moment, other civilizations may still be far ahead of humans in certain side technologies.

Strengthening scientific and technological exchanges and expanding the scientific and technological territory is also a kind of accumulation, which is extremely beneficial to the third level of civilization impact.

Not to mention the benefits of having a younger brother, such as the distribution and integration of commercial and industrial systems, and serving as an outpost to explore paths.

Human civilization can also legitimately "exploit" the other three civilizations and obtain the largest benefits in the production system.

Of course, this kind of exploitation is different from when the Eta civilization colonized the solar system. If Han Yang is allowed to lead this kind of exploitation, then the situation will be that humans eat meat and other civilizations eat soup, which will also be beneficial to other civilizations. It can also promote the development of science and technology and comprehensive strength of other civilizations to a certain extent, but the benefits are not as good as those of humans. The one you got is just big.

However, although there are many benefits to assisting other civilizations, after Han Yang's comprehensive evaluation, they are not so many that it is necessary to do so.

Overall, the benefits are there, but not much and not interesting.

It just so happened that you civilizations started to be wary of me, fearing that I would destroy you, so I didn’t bother.

This situation continued for several years. Until a certain accident happened, which made Han Yang realize that he might have to support those three civilizations. (End of chapter)
