Start sweeping the universe by rubbing the CPU with your hands.

At this moment, Han Yang can finally devote all his computing power to the iteration of various equipment.

Controlled quark fission devices, artificial gravity devices, super-light navigation devices, and secondary technologies such as gravity shields, gravity cannons, and gravity bombs based on this technology must become smaller and smaller in size and mass. Low, performance needs to be higher and higher, more reliable and more precise.

The entire human scientific community, as well as almost all of Han Yang's computing power, were devoted to this work.

Among them, Han Yang still adopted a research and development approach regardless of investment. Any path that has the potential to break through, as long as there is still some hope, will be tried. Only when it proves that a certain path really doesn't work, will it be given up.

As for how much manpower and material resources were wasted in this process, it doesn't matter, Han Yang can afford it, and the human world can afford it.

Under such circumstances, the progress of various important technologies is advancing rapidly.

In addition, the military community is not idle either.

In addition to still leading the war with the four major civilization alliances and trying to delay time, another important task of the military community has become the task of researching the strategies and tactics of new wars under the new technological level of the fourth-level civilization.

Although humans are still unable to build up-to-standard fourth-level civilization warships at this moment, people know what performance standards those warships have. In this case, the conditions for simulation are met.

People have specially developed a war system that simulates as much as possible. In the virtual world, human commanders and staff command virtual warships to launch wars, in order to accumulate war experience and prepare for the real four battles that will surely follow. Provide theoretical basis for wars between super civilizations.

At this stage, it is the aspect of war theory that Han Yang values ​​​​the most. As for how to train specific soldiers and how to set up a system, Han Yang didn't pay much attention to it.

Because Han Yang has decided that in the future war with Yunguang Civilization, he will not let human soldiers take the field. Instead, he will operate the dummies directly.

However, it is said that it is operating a dummy, but it is actually just a show. All the battleships will be controlled by Han Yang himself. Those dummies are nothing more than placed in the cabin. Once the battleship is destroyed, the enemy will find the human remains, so they will not doubt that these are unmanned battleships, and then doubt their own existence.

Anyway, those dummies were secretly made by Han Yang using cloning technology. Except that they did not have their own thoughts and could only be controlled by Han Yang, their body structure was exactly the same as that of real people, so there was no need to worry about being discovered.

This war is so important that it is almost directly related to the life and death of human civilization. The task of scientific and technological research and development is too urgent, and the time left for mankind is too short, and there is no time to carry out large-scale soldier training. Han Yang playing in person is the only chance to win this glimmer of hope.

Under this situation, about 30 years later, after rapid iteration, the first batch of fourth-level civilization warships with actual combat capabilities were finally produced.

The total number of this batch of warships is 1000. So, after decades of simulation exercises, human commanders and staff can finally use real fourth-level civilization spacecraft to start a battle.

In any star system, where there is no need to worry about being discovered by any being, this fleet launched a fierce battle.

After all, actual combat exercises are different from simulation exercises. During this process, more problems that could not be exposed in simulation exercises were exposed, and they were quickly improved through iteration and optimization.

The emergence of these 1000 level- civilization warships is not the end of human civilization's research on spacecraft manufacturing technology, but a new starting point.

Time flies by, and another 10 years have passed in the blink of an eye. At this moment, with nearly a million technological innovations, Han Yang finally issued a technology freeze order.

The latest warships will be based on these technologies. From then on, in the near future, even if new technologies emerge, there will be no major revisions and upgrades to the warships. Instead, they will accumulate, and when the accumulation reaches a certain level, they will undergo a major update.

While technology is frozen, production capacity has also been prepared in advance. As a result, the large-scale, almost violent battleship manufacturing project officially began.

In order to speed up this process, Han Yang also invested almost all his computing power in addition to the regular construction tasks involving human engineers and technical workers.

It has been many years since Han Yang devoted almost all of his computing power to construction tasks.

His computing power is usually only invested in technological research and development, and he is not even invested in wars that are more significant to civilization. He will only leave them to human warriors to execute.

But now, after so many years, Han Yang made this choice again.

Compared to Han Yang, who has been upgraded many times - after being promoted to a fourth-level civilization, computer technology has developed again, and the computing power controlled by Han Yang has increased by more than ten times - after mastering such a huge computing power, If all of it is invested in the spacecraft manufacturing industry, how powerful a production capacity can be unleashed?

The answer is that in just ten years, Han Yang has built up to 50 level civilization-level spaceships - although these level civilization-level spacecraft are more complex in structure than those of level civilization. , the technology is more advanced, and the corresponding manufacturing is more difficult.

Among these 50 fourth-level civilization level spacecraft, there are 100 dwarf planet-class battleships, 2500 asteroid-class battleships, and 3 nebula-class battleships, as well as the largest number of starships, more than 42. Dust-class battleship.

The total number of warships is approximately 46, and the remaining approximately 4 spacecraft are supporting auxiliary spacecraft, such as space carriers, interstellar transport ships, supply ships, base spacecraft, life-support ships, rescue ships, minesweeper ships, Minelayers, spy ships, probe ships, etc.

In addition to battleships, there are an almost immeasurable number of fourth-level civilization-level spy satellites, detection satellites, military satellites, interstellar mines, turrets, missiles, and so on.

It can be said that human civilization at this moment fully possesses the military reserves to carry out a large-scale fourth-level civilization war.

At this moment, Han Yang's heart, which had always been hanging, finally settled.

Human civilization already has the capital to fight against Yunguang civilization.

Although Yunguang Civilization, as an old fourth-level civilization, must have more advanced technology and more powerful military power than humans, at this moment, human civilization is no longer without the slightest resistance.

Coincidentally, in the interstellar battlefield at this moment, the strategic deception plan implemented by Han Yang has reached the point where it is almost unsustainable.

No matter how realistic it is and how real it seems, a scam is still just a scam. As time goes by, it will always be exposed.

Previously, Han Yang originally planned to gain 100 years of development time for himself by launching a suicidal attack on the four major civilizations. Now, only 86 years have passed, and this scam has already shown signs of being unsustainable.

The four major civilization coalitions have become increasingly restless and impatient.

The reason is simple. They had been waiting for the Pan-Sun Alliance to reveal flaws due to internal conflicts. In the past hundred years, it seems that the Pan-Sun Alliance has been riddled with contradictions, and its defense line seems to be in danger. It seems that it almost collapsed several times due to insufficient tacit understanding and timely mobilization, but in the end it was always able to turn the corner.

A large number of fleets began to gather around the Nanmen II system again, and a large-scale battle was brewing. Either break through the South Gate II System and achieve major results, or give up altogether and directly cause all the participating soldiers to commit suicide, creating an excuse for the end of Yunguang Civilization. Once again, they have become two options before the heads of the four major civilizations, and they must choose one of them.

It is impossible to continue to deceive and procrastinate. But Han Yang didn't intend to delay it any longer.

"Show true strength directly and annihilate the four major civilization coalitions?"

During the military meeting, Liu Yuan slowly shook his head: "No.

The fact that our side already possesses the combat power of a fourth-level civilization is still a secret until now, and Yunguang Civilization does not know about it. This is a great advantage for our side. In the war, we can use this to gain huge opportunities and results.

Therefore, the combat power of our fourth-level civilization cannot be exposed in the solar system. At the same time, we cannot take the initiative to launch sneak attacks on Yunguang Civilization.

As strong as Yunguang Civilization, it still needs to find so many excuses to deal with us. Although it is certain that it is not entirely due to concerns about interstellar influence, it is undeniable that interstellar influence is also an important factor.

To wage an undeclared war and launch a sneak attack will bear a huge moral responsibility. On the surface, there will be no losses, but in terms of soft power, there will be a lot of losses. We will not do this.

Then, the only solution is to use the combat power of the Pan-Sun Alliance to annihilate the combat power of the four major civilization alliances.

There is no doubt that we can do this. But it is undeniable that this will also cause us, and our allies, to pay a considerable price.

At the third-level civilization level, the fleets of the four major civilizations are not weak. Just because they can't break through our defenses doesn't mean we can easily annihilate them.

Even if the fleets of the four major civilizations are ready to commit suicide, the suicide must only occur after fighting with all their strength and confirming that there is no hope of victory. And this will also cause heavy casualties to the allies.

In order to hide our strength and make our allies pay a heavy price, it is not in line with our values.

Values ​​can be violated if necessary, but they cannot be violated easily for such a trivial matter.

Then...weakening the strength of the four major civilization coalitions so that our allies can annihilate them more easily is the most appropriate plan. "

A smile appeared on Liu Yuan's face: "If the coalition forces of the four major civilizations suddenly learn that the civilized homeland is attacked by an unknown fourth-level civilization and that the civilization has perished, I don't know... how much will they still have to fight?

It just so happens that the combat power of our fourth-level civilization has never been tested in actual combat. Even if it is just actual combat experience against a third-level civilization fleet, it is still of high value..."

Li Hai, the commercial commissioner of human civilization who is responsible for negotiating with Luo Tu civilization, once again found Luo Zhaoyangdong.

"Hello, Mr. Li Hai, Luotu Civilization is at your service wholeheartedly."

Luo Zhaoyangdong was smiling and very friendly.

Li Hai also smiled and said: "I am looking for you this time because I hope to entrust your civilization to do something for us.

The situation is like this. The four major civilizations of Hongyang, Uta, Blackwater, and Snowland will encounter our sneak attacks in the near future.

Or it can't be called a sneak attack. After all, we are both at war right now.

It’s just that we don’t want the outside world to know that it was our civilization that attacked and destroyed the four major civilizations.

However, the fact that the four major civilizations were destroyed due to an attack by an unknown civilization will definitely attract the attention of the Silver Alliance and lead to an investigation. And the Yinmeng investigation will reveal our identity. We hope your civilization will delay the investigation process for ten years. Ten years later, we will take the initiative to expose our identity and lift the Yinmeng investigation. "

This is a plan that Han Yang and the ruling committee members have already agreed on.

In this way, human beings can destroy the four major civilizations without exposing their own strength, and at the same time weaken the strength of the four major civilizations' coalition forces, allowing their allies to annihilate them without paying a high price.

Luo Zhaoyangdong's expression changed and he asked tentatively: "You... have made a breakthrough?"

Li Hai smiled and nodded.

Luo Zhaoyangdong said sincerely: "Congratulations. It's beyond imagination to be able to break through under such unfavorable conditions. It seems that the strength and potential of your human civilization exceeds my previous expectations.

I can respond to the tasks you entrust. We can accept this commission. What's the price? I'll give you a preferential price of 500 million silver coins. "

Li Hai's face instantly turned into a bitter melon: "Your Excellency Luo Zhaoyangdong, the price of 500 million silver coins is too high. Our breakthrough has exhausted all the resources of the civilization, and now we are really financially tight and we cannot afford it. "

Luo Zhaoyangdong sneered at Li Hai's excuse: "You can fool others, but you can't fool me. During this period, your human fleet has been attacking everywhere and doing tasks desperately. You have already accumulated at least several billion silver coins. You can even take 500 million." Not coming out?"

Li Hai continued to complain: "We also need an explanation from our allies. Besides, when our civilization truly reaches the level of fourth-level civilization, we can openly buy scientific and technological materials from your civilization. By then, the transaction amount will not be as high as It’s just a matter of a few hundred million or even billions of silver coins.”

In this way, after some pulling and bargaining, the two parties finally reached a price of 3.5 million silver coins and reached a cooperation.

After the news was reported, Han Yang felt a little emotional.

"I originally thought that the counteroffer could only reach 4.5 million silver coins at most, but I didn't expect that we could negotiate for 3.5 million silver coins. This Luotu civilization is really addicted to silver coins.

There should be some reasons why Luotu civilization has good intentions towards us humans, but this is not enough to explain everything. There must be another reason why the Luotu civilization has shown a stronger and more urgent desire to earn a large amount of silver coins than other level five civilizations. "

But this has nothing to do with human civilization. There is only one thing that Han Yang pays attention to at this moment.

That is, I can finally destroy those four hateful civilizations without any scruples or burdens. (End of chapter)
