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

The four heads of civilization each laughed off the accusations.

Especially after seeing the condemnation statements from civilizations such as Chitie and Ziyun, Han Yang was not angry at all, but full of admiration.

"It's times like this that make us follow the crowd... You did the right thing."

Subsequently, the four founding civilizations also publicly issued a statement in the name of the Silver Alliance.

There was nothing new in the statement. It was nothing more than condemnation and threats. In the end, it even claimed that the Four-Party Alliance should be dissolved immediately and that the member civilizations must accept the management of the Silver Alliance, otherwise the Four-Party Alliance would be destroyed.

It was a routine operation to exchange verbal attacks before the battle. In fact, if it wasn't for the future integration of the Milky Way, the four leaders of the Quad Alliance would not even want to issue a notice, and would just send their fleets directly to the black hole at the center of the Milky Way.

Nothing has changed at this moment.

After the verbal attack, the four-party alliance immediately set out, with high morale and vigor, and rushed straight to the black hole at the center of the Milky Way.

Driven by the powerful space engine, the human microcosm with a radius of up to five light years is advancing at a speed hundreds of times the speed of light.

In order to propel such a huge microcosm, an entire planet as large as the Earth would be consumed for almost every 10 light-year journey. But compared to the engineering power that human civilization possesses at the moment, this consumption is nothing.

Even the Lotu and Greenoka civilizations didn't care much.

If there are no resources left, just move a planet from the Milky Way and put it in.

Compared with energy consumption, the problem of entropy increase in the microcosm is of greater concern to the four major civilizations.

An isolated system will always go from order to disorder on its own, just like a house that will always become more and more messy instead of tidy if no one cleans it.

Without being connected to the big universe, the micro-universe can also be regarded as an isolated system, and its entropy will always increase.

The increase in entropy will cause the entire universe to be filled with unusable "waste heat", and eventually the entire microcosm will die.

This is commonly known as heat death.

Once heat death occurs, even time will stop.

Of course, time is not a separate physical quantity, but is used to describe the change of state of an object. However, once heat death occurs, there will be no more physical changes in the microcosm, just like a pool of stagnant water, and it is not wrong to think that time has stopped.

However, any human activity will accelerate the increase of entropy rather than cause the decrease of entropy.

Take a refrigerator for example. It seems that the refrigerator creates low temperature inside, which is equivalent to reducing entropy. However, in this process, for a relatively small low temperature, it releases relatively more high temperature to the outside world. Overall, it is still accelerating entropy increase.

The huge energy consumption of one Earth for every 10 light years will also create more entropy.

In today's small universe, the speed of time flow has become slightly different from that of the three-dimensional universe due to the increase in entropy.

Fortunately, the difference is so small that it will not have any meaningful impact for the time being, and will not cause unacceptable consequences even in the foreseeable future.

Even if there is an impact, the connection between the small universe and the three-dimensional universe will cause the excess entropy to be "discharged" into the three-dimensional universe, reducing the entropy of the small universe again.

This issue requires attention, but you can ignore it for now and just treat it as a long-term research topic.

Time passed quickly. In just a few years, the Four Alliances had already arrived at the core area of ​​the Milky Way.

At this moment, the Quad Alliance Fleet is less than 100 light-years away from the central black hole of the Milky Way.

At this moment, a strange scene appeared before Han Yang.

The center of the Milky Way is the place with the highest star density in the entire Milky Way. Here, there is an average of more than one star per cubic light-year. In contrast, around the solar system, there are only 0.004 stars per cubic light-year.

Here, the entire sky is filled with shining and bright stars. Every place, every space, no matter which direction you look, is bright.

There is no night here.

One direct effect of the numerous stars is that the radiation here is extremely strong. After a rough observation, Han Yang can determine that even a Level 5 civilization ship has to be very careful when coming here. If they are unlucky and encounter a radiation explosion, a Level 5 civilization ship will be destroyed.

This is still under normal circumstances. In abnormal situations, such as a planet the size of the Earth falling into the black hole at the center of the Milky Way, the radiation it releases will be hundreds or thousands of times greater than normal, and the environment will be even worse.

Within a radius of only 100 light years around the black hole at the center of the Milky Way, hundreds of millions of stars are spinning frantically around it. It is filled with interstellar dust, and endless dust is spinning and falling into the black hole, making it the strongest radio source in the entire Milky Way.

The environment here is harsh, but this is also the place that all level six civilizations dream of.

Because this place carries the hope for further development of Level 6 civilization.

The Pangu civilization once fought here and eventually disappeared. Now, led by human civilization and led by Han Yang, the powerful fleet of the Four Alliance has returned here.

When they reached this distance, the powerful fleet of the Quartet Alliance had to stop temporarily.

Ahead, the defense line of the Creator Civilization is already in sight.

Even Han Yang today couldn't help but be shocked by the scale of the Founder's Defense Line.

Around the black hole at the center of the Milky Way, Han Yang detected spatial fluctuations caused by the existence of at least 10,000 microcosms. At the same time, he saw traces of high-energy flashes next to more than 10,000 stars.

Ten thousand stars, ten thousand bases, and ten thousand small universes, united together, are like a giant net, covering the black hole at the center of the Milky Way without any blind spots.

Unless any external force breaks through this line of defense, it will be impossible for them to get close to the black hole at the center of the Milky Way.

The four-party alliance must eradicate all of these more than 10,000 small universes, bases, and fleets. Otherwise, even if a breakthrough is achieved, it will be impossible to complete the subsequent experiments.

The ultra-large-scale high-energy experiment based on the black hole at the center of the Milky Way is something that even the Pangu civilization could not complete on its own. Instead, it had to train comrades in arms in order to have any hope of completing it. You can imagine how large its scale is.

Such a huge project can only be completed in an absolutely safe and undisturbed environment. Therefore, there cannot be any threats around the black hole at the center of the Milky Way.

Han Yang knew clearly that conducting ultra-large-scale high-energy experiments around the black hole at the center of the Milky Way would indeed lead to the connection with the "antimatter universe", thus causing the destruction of the Milky Way.

If that happens, all civilizations in the Milky Way, including human civilization, will be extinct, and it will be impossible for any civilization to survive.

However, the probability of this experiment causing the destruction of the Milky Way is not that high, only about 10% probability. If the engineering control is fine enough and careful enough, the probability can be reduced to even less than 1%. With Han Yang's own special characteristics, he is confident that he can do this.

However, based on the model assessment established by Han Yang based on the development conditions of strange life in the two major galaxies, "strange life in the Milky Way is frequently eliminated" and "strange life in the Canis Major dwarf galaxy has not been eliminated at all", Han Yang believes that there is a 90% probability that the emergence of level 100 strange life will not be later than million years in the future.

Within 200 million years, the probability of the emergence of level 99.99 strange life is as high as %.

So, should we accept the certain extinction within 200 million years, or choose the 1% probability of extinction at this moment and fight for a future?
Rather than being trapped and dying in the Milky Way, waiting for the strange life to evolve to a higher level, and slowly dying in this situation like a frog in boiling water, Han Yang would rather live towards death and directly fight for the possibility of being promoted to a level seven civilization.

This was the choice made by Pangu Civilization at the time, and the other three level six civilizations in the Four-Party Alliance also made this choice.

This decision seems to ignore the right of choice of lower civilizations, but it is obvious that in a normal family, adults will not consider the opinions of young children when making certain important decisions that affect fate, life and death.

The gap between low-level civilization and level-six civilization is more than just the gap between a toddler and an adult.
Moreover, once the experiment is successful, the benefits will be shared by all civilizations in the entire galaxy. At the same time, Han Yang can ensure that if the experiment is really carried out in the future, every low-level civilization, even primitive civilization, will be protected by a level 6 civilization, so that it will be protected by the same level 6 civilization itself.

Han Yang and every head of state in the four-party alliance believed that taking all factors into consideration, the decision at this moment was the best one.

At this moment, facing the numerous small universes surrounding the center of the Milky Way, in the virtual combat conference room, Huo Xiyu, the head of the Luotu civilization, sighed: "It is worthy of the defense line that the founder civilization spent millions of years to build..."

Han Yang controlled Shen Hua with a calm expression: "No matter how huge the defense is, it can't stop us.

I order the fleet to move out!"

"set off!"

The four heads of state each issued their orders solemnly.

The next moment, the four fleets of the Quartet Alliance in the four directions around the black hole at the center of the Milky Way each dispersed into five to ten group fleets and rushed towards this line of defense respectively.

The Creator's defense line also immediately took action. Amidst the violent space shock, numerous small universes and a large number of superluminal warships began to move.

The war has already begun even during the superluminal travel.

At the sixth level of civilization, based on a deep understanding of space theory, warships can already directly enter or exit the superluminal state in places with strong gravitational fields, and can also launch attacks on the enemy in the superluminal state.

At this moment, based on the space vibration detection, the targets of both the enemy and us were presented on the chaotic space-time image of the galactic center area. Under the powerful energy supply of the quark fission-fusion dual reactor, with antimatter as the catalyst, invisible space blades violently slashed into the surrounding empty space.

This is a tear from the space level. Unless there is a space shield that can stabilize the surrounding space and prevent it from being torn apart, no matter how strong the armor or shield is, it cannot stop it.

In a flash of fighting, more than 100,000 warships on both sides were destroyed.

Once the battleship is destroyed, the equipment used to maintain the curvature of space will immediately lose its effect, the curved space will instantly become chaotic, and the battleship will be torn into pieces, leaving only the most basic microscopic particles. Apart from that, not even a trace of wreckage will be left, let alone biological limbs.

In such a huge battlefield, death is just a matter of a second. Most of the time, the soldiers in the spacecraft can't even react, can't even feel pain or fear, and the whole person has turned into microscopic particles.

Space is torn, twisted, exploded, and annihilated. Countless space-based weapons are exerting their power wantonly around the black hole at the center of the Milky Way.

In the seemingly peaceful space, a flash of light would suddenly burst out at any time, and hundreds of soldiers would die instantly;
A warship that is hiding and traveling at superluminal speed may be suddenly attacked by a superluminal missile and its surrounding space may explode at any time. The next moment, the warhead of the missile explodes suddenly, and the power of the space annihilation bomb will instantly destroy the balance of space, causing all visible and invisible existences in this distorted space to be destroyed into microscopic particles.
Endless space mines were like piranhas hiding in the dark, ready to jump out at any time to disrupt the space and kill the opponent. Under the siege of numerous space mines, even the star-class battleships equipped with the strongest space shields could not resist.

In this unimaginably fierce battle, even the naturally existing stars were affected.

Han Yang saw a planet as large as Jupiter, which suddenly exploded like a dead star, and all the gases that made up the planet were thrown into the universe;

A white star that was twice as big as the sun suddenly turned blue. The star activity became more than a hundred times more intense, and even within a day, it threw out a mass equivalent to a thousand Earths, turning this star region into a purgatory.
As for the asteroids, dwarf planets, comets and the like that disappear in an instant or explode into interstellar dust, there are so many of them that they cannot be counted.

Han Yang knew that the galactic center region was now in such chaos that even if a large fleet of a level five civilization arrived, it would be silently annihilated in an instant.

If you are not at the level of a sixth-level civilization, you are not even qualified to watch this war. Even if you are at the level of a sixth-level primary civilization, even if you are not attacked deliberately, just surviving in the current environment is already the limit.

At this moment, even Han Yang had to admit that he had underestimated the creator civilizations before.

In Han Yang's view, they were nothing more than four ordinary level 6 civilizations. Facing himself with special abilities and his army of hundreds of millions of warships, it was no problem to destroy them in one fell swoop.

However, after operating for millions of years and through a special form that is both independent and integrated with each other, the strength of the Galactic Center Defense Line has truly exceeded one's imagination.

There are more than 10,000 small universes, each of which stores countless automated combat facilities and has a complete industrial system.

There are more than 10,000 key node star systems, and each star system is like an iron wall that even Han Yang finds difficult to break through.

If it had not been proven long ago that strong artificial intelligence was not feasible at least at the sixth level of civilization, Han Yang would have doubted that the Creator Civilization had already mastered this technology.

Otherwise, how could the scale of their war facilities be so huge?

"This is the heritage of an old-fashioned level six civilization... Perhaps their artificial intelligence has been honing its skills on the galactic center defense line for millions of years and has been 'fed' by data for millions of years. Even if it is not true strong artificial intelligence, it is barely close to the effect of strong artificial intelligence in terms of warfare..."

However, Han Yang was not afraid at all.

No matter how close it is to strong artificial intelligence, it is not true strong artificial intelligence. It must be dominated by real intelligent life.

And at least at the sixth level of civilization, my strength is no different from that of a true strong artificial intelligence!
Isn't it just a matter of consumption and a competition of war potential?

How could you possibly be my opponent!
If one thousand years isn’t enough, then two thousand years. If two thousand years isn’t enough, then ten thousand years. Even if it’s a hundred thousand years, I can eventually wipe you out.

Han Yang's fighting spirit is stronger than ever.

Under his leadership, a huge fleet flowed out of the human microcosm like water and was thrown into the battlefield. In the microcosm, trillions of humans, on tens of thousands of planets, were carrying out large-scale production day and night.

The same is true for the Luotu civilization, the Greenoka civilization, and the Wanyue civilization.

Every civilization is desperately carrying out production and military training. The entire civilization has completely transformed into a wartime system.

Birth restrictions have long been lifted, and encouraging childbirth has become the mainstream voice of every civilization. Even cloning technology has been lifted, and every civilization is mass-producing babies, raising them in groups, educating them in batches, and then sending them to the battlefield.

Every civilization is doing its best.

Every intelligent lifeform deeply understands that the war at this moment is not only to fight for the development space of other civilizations in the Milky Way, but also to fight for the development space for their own civilization and themselves! (End of this chapter)
