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

It turns out that human beings have secretly advanced to a fourth-level civilization... but they have been hiding it, making themselves mistakenly think that they are still a third-level civilization, so that they can head to the solar system rashly, and then they have set up gravity traps around the galaxy. The trap is just waiting for us to plunge into it...

Ridiculous, in vain, I kept stressing that we should be careful and careful, but in the end, we fell into such a cheap trap, and lost 50,000 battleships and tens of millions of soldiers in one fell swoop...

That's 50,000 warships! At this stage, there are only so many warships defending the capital galaxy. As a result, they were lost here all at once, and they were gone all at once, without even a splash...

Since human civilization has already been promoted to the fourth level civilization, then the four civilizations of Hongyang, Blackwater, Uta, and Snowland should not have been destroyed by others, but by humans, right? Ridiculous, we actually thought it was done by a malicious civilization, and we are still asking the Silver Alliance to conduct a thorough investigation...

Um? Why is the Yinmeng investigation so slow? Before, I thought it was the Silver Alliance itself that was dragging its feet, but now it seems that it is most likely that humans spent money on it and deliberately delayed it...

Deliberately making us think that there is interference from outside forces, we chose to dispatch so many fleets to attack the solar system. After arriving in the solar system, they focused most of their efforts on preventing interference from external forces, while ignoring human civilization itself. In the end, they laid a trap and destroyed 50,000 of our warships in one fell swoop...

Human civilization is good at planning and means...

In endless pain and regret, Commander Lultan finally lost consciousness completely.

There was chaos in the battleship Guangxing, and there was still joy in the human fleet headquarters.

Every high-level human being was smiling. They felt that most of the gloom that had weighed heavily on their hearts for hundreds of years had dissipated in an instant. They felt that hundreds of years of struggle finally made sense.

Although there will definitely be a big battle next, and it will definitely not be easy, but at least now, our side has achieved extremely huge results.

This opportunity only comes once, if you miss it, you won't get it again. As long as the Yunguang Civilization knows that human civilization has become a fourth-level civilization, even if it is only the most rudimentary fourth-level civilization, they will definitely be more vigilant, and it is impossible to fall into such a low-level trap.

Fortunately, even if the trap was so inferior this time, coupled with the early strategic deception, it still achieved huge results.

There is no way, unless it reaches the level of sixth-level civilization, otherwise, even a fifth-level civilization, if it suddenly encounters gravitational interference while traveling at super-light speed, will directly destroy the stability of the space bubble, which will lead to the destruction of the spacecraft, not to mention the destruction of a mere four-level civilization. super civilization.

"Okay. The enemy has suffered such heavy losses, and the next revenge will be fierce. Be prepared to continue fighting."

Following Liu Yuan's words, the cheers and applause of the people in the headquarters slowly subsided, but the excitement on their faces was still hard to conceal. I also quietly felt a little more hopeful about the coming battle.

Han Yang did not take advantage of this opportunity to take the initiative to attack the Yunguang fleet. Because he knew it was of no use.

Your own strategy is to defend, so just defend. Attacking rashly is not only inconsistent with the overall strategy, but can also easily cause unnecessary losses.

Time passes bit by bit, and around the solar system, with Pluto as the boundary, all the outer planets have abandoned their defense, and all the inner planets are on standby.

While the Yunguang fleet was digesting its losses and deploying its next tactics, the human account of Yinmeng.com also issued an announcement.

The announcement directly declared that Hongyang and other four major civilizations had perished before, and it was done for human civilization. Anyway, the two sides have been at war for hundreds of years. No one can say anything wrong with destroying them. It is better to admit it directly and make some claims. Possession of the four major civilizational heritages.

Although the heritage of the four major civilizations is not much, they add up to more than one billion silver coins, which is a large amount of loot.

With the preliminary preparations made through Luotu Civilization activities, this loot was quickly distributed to human accounts, and it was a medium-sized sum.

Afterwards, mankind once again claimed that in the face of the shameless aggression of Yunguang Civilization, human civilization had achieved preliminary results in the galaxy defense war, annihilating up to 50,000 warships of Yunguang Civilization in one fell swoop, and sternly warned Yunguang Civilization to stop the invasion immediately. Leave human territory and compensate for human losses, otherwise you will be responsible for all the consequences.

The third announcement is that human civilization generously acknowledges that it has successfully promoted to a fourth-level civilization, and in the future "can better assume the responsibilities of the Silver Alliance, fulfill the obligations of the Silver Alliance, and maintain peace in the galaxy."

The first announcement was better, after all, not many people actually cared about the demise of those four civilizations. The second and third announcements shocked countless people.

A third-level civilization was suppressed by a fourth-level civilization and achieved technological advancement through the purchase of scientific and technological materials. It was actually able to rely on its own strength to master the theory of everything, successfully promoted to a fourth-level civilization and transformed technology. For the sake of combat effectiveness, 50,000 warships of the veteran fourth-level civilization Yunguang Civilization were wiped out in the first battle. This is really amazing and incredible.

No matter what thoughts you have about human beings, there is one thought in common.

This human civilization is probably not something that exists in a pond...

The rest of the civilization didn't matter, but the senior officials of the Yunguang Civilization were pissed off to death by a series of human announcements.

What do you mean? It was not made public for so long, but it was made public as soon as our Yunguang Fleet was fooled and suffered a big loss. It was obviously waiting to deceive us, right? If you don't trick us, you won't make it public, right?
Gritting his teeth with hatred in his heart, he wished he could crush all the hateful humans to ashes, but Commander Lultan no longer dared to advance or despise human beings.

He re-planned the battle plan, played a steady role, and began to use conventional propulsion methods from a place more than two trillion kilometers away from the sun, approaching the solar system at sub-light speed, for fear of encountering another ambush.

"Even if human beings have become a fourth-level civilization, they are only in the primary stage. The accumulation of relevant technologies is not strong enough, the performance of various creations is not advanced enough, and the combat effectiveness is very different from ours.

Once a head-on battle begins, mankind will definitely lose! "

Lultan had absolute confidence in winning the next war.

A few months passed quietly, and amid constant small-scale harassment battles, the Yunguang Fleet finally advanced to a place only a few hundred million kilometers away from the orbit of Pluto.

Pluto is now on the other side of the sun. The one facing the Yunguang Fleet's military peak was Neptune.

There are up to 40 human warships gathered here on Neptune at this moment. This number accounts for 80% of the total number of warships in the Solar System, and 40% of the total force of the Solar System, Nanmen II, Lutan, and Tianyuan IV, the four human-defended systems.

At this moment, the human population of hundreds of billions is only concentrated in these four galaxies. The total strength of these four galaxies combined is no more than 100 million battleships, and Neptune only accounts for less than half of it.

But even so, even if our own side has 40 ships compared to Yunguang's 25 ships, it seems that our side has an advantage, but the actual situation is that the human side has an absolute disadvantage. After all, our own technology is far behind the other party's. Our own side can't even build a satellite-class battleship!

But even so, Han Yang is still absolutely sure to defend Neptune, and even every planet in the solar system.

the reason is simple.

Automated defense facilities!
The production of warships is a matter of an entire technological system and is subject to many constraints. The production of automated defense facilities is much simpler, and astronomical numbers can be piled up easily.

Besides, Han Yang didn't want to repel the Yunguang Fleet, he just wanted to defend it, so the strategic difficulty was naturally even lower.

As for the battleships that have gone to Neptune, what about the other planets in the solar system?
It's also very simple. If the Yunguang Fleet goes to attack other planets, it will be enough for the warships from Neptune to follow. Anyway, there is no way to travel faster than the speed of light in the solar system. For normal navigation, everyone has similar maneuverability, and no one can run faster than anyone else.

Under such circumstances, the war finally broke out around Neptune.

As soon as the war began, Han Yang noticed the huge gap in combat power between the two sides.

In addition to the fact that conventional spacecraft shields are tougher, gravity cannon projectiles are faster and more powerful, laser beams are more powerful, interstellar missiles and interstellar mines are more maneuverable and more powerful - although this is already an extremely huge gap , enough to create a generation gap and crushing, but it was within Han Yang's expectation and did not surprise Han Yang.

In addition, several new weapons mastered by Yunguang Civilization really exceeded Han Yang's expectations.

Han Yang suddenly discovered that after the projectile of Yunguang Civilization's gravity cannon hit the target, there would be an additional explosion - not a conventional quantum or quark excited state explosion, but more powerful than that. Large, but it obviously couldn't be a quark fission type explosion, because it couldn't be so small.

This caused the power of the Yunguang Civilization's gravity cannon to rise sharply, causing heavy casualties to Han Yang in a short period of time.

After urgent research, Han Yang finally made a more accurate guess. He speculated that this may be causing the material to be in a state of extreme compression. After suddenly losing its restraint, it exploded due to electron degeneracy pressure. Its state is probably similar to the explosion that occurs after the material of a white dwarf or neutron star breaks away from the star.

Of course, the power is not as powerful as the genuine white dwarf material explosion, but the basic principle should be similar.

As for how to do it, Han Yang was puzzled.

Another unexpected thing is the gravity shield of Yunguang Civilization.

They seem to have adopted multiple, mutually matched gravity distortion schemes, by laying out multiple layers of gravity fields of different directions and strengths in a small space, to achieve far beyond ordinary protection capabilities.

This is another technical blind spot that Han Yang has never been exposed to.

As for what is applied to interstellar missiles, what is applied to laser cannons, what is applied to spacecraft structures, etc., there are countless details.

The total disparities in all aspects gave Han Yang the feeling of using a millet and a rifle to shoot an airplane or a cannon.

Fortunately, Han Yang's initial preparations were sufficient and the overall strategic goal was set low enough - not to repel the enemy, but only to defend the planet, so he could barely maintain the defense line.

Lultan gritted his teeth, determined to capture this big planet and brutally massacre it to repay his hatred. On the human side, Han Yang personally took the stage and personally controlled hundreds of thousands of warships. He maximized mutual cooperation, coordination, and tactical advantages, and coupled with a vast amount of automated defense facilities, he blocked Yunguang's attack. Outside, don't let a single pellet, not a single cannonball land on one of Neptune's moons.

The battle lines were at a stalemate under this situation.

On the other side, people in the four major galaxies are still trying their best to produce warships one after another. However, without the addition of Han Yang's computing power, the production rate has been reduced a lot, with an average of only a dozen ships per day, which is far from keeping up with battlefield consumption.

"Fortunately, we managed to kill 50,000 warships of Yunguang Civilization right from the beginning. Otherwise, Neptune might not be able to defend it..."

At this moment, Han Yang couldn't help but sigh in his heart about his luck.

only……

"It won't work if we continue like this... If we continue like this, it won't take more than a few decades for my defenses to collapse. And the collapse of Neptune will inevitably lead to the collective collapse of the defense systems of other planets. By then, the solar system will be lost. ”

There is no doubt about the power of Yunguang Civilization, and the situation is extremely serious. But Han Yang was not very panicked.

Because, after this period of delay, the huge fleet of about 50 warships heading to the Yunguang Galaxy was finally about to break away from the super-light speed of navigation.

At this moment, this fleet is still about 2.5 trillion kilometers away from the Yunguang star.

The mass of the cloud-light star is larger than that of the red-sun star, which means that under extreme circumstances, the distance that the warship built by Han Yang can escape from the super-light speed of navigation has also expanded to 1.3 trillion kilometers.

However, Yunguang Civilization is a fourth-level civilization after all. They used a special gravity generator to create a gravity defense line around the capital galaxy, extending the distance that Han Yang's fleet could escape from super-light navigation by another trillion kilometers.

Coupled with some margin left to ensure safety, in the end, Han Yang could only break away from super-light navigation at this distance.

However, although the distance is a little farther, up to 2.5 trillion kilometers, it doesn't matter, it is still within Han Yang's tolerance.

The next moment, accompanied by a slightly illusory change of light and shadow, up to 50 warships appeared from the void at the same time. The next moment, under the full power supply of the quark fission reactor, the fourth-level civilization-level non-working propellers pushed forward with all their strength. While maintaining a strict formation, these warships instantly began to move at a speed of up to 1600 meters per square second. , began to accelerate towards the interior of the cloud-light galaxy.

"Dare to attack our capital galaxy of humanity? It's disrespectful to come back without reciprocating!" (End of Chapter)
