The seven small spaceships, as if predicting the danger of the situation, instantly broke out into the strongest offensive.

The silver crystal spaceship's whole body suddenly bloomed into a phantom that was millions of times larger, and then it was instantly compressed into a point, and a silver light spurted out, and disappeared in the blink of an eye, aiming directly at the stargate of the Darker Zerg.

The small black spaceship, the bow of the ship condensed a black sphere that could absorb all the light, constantly expanding and expanding, and in the blink of an eye, the black ball was hundreds of times larger than the volume of its hull, and the bodies of the black insects that approached were twisted and absorbed into it,...... However, the black boat's whole body shook, like a 'black hole', and the sphere of distorted space was ejected by it, and the target was also the stargate where the new insect tide appeared.

The small red spaceship, the whole body turned from red to purple, like a flower blooming, the bow of the ship cracked in all directions, revealing a purple energy crystal in the center, and then spewed out, thundering,...... , a dazzling red light in the dark space.

……

Each of the seven small ships used their 'killer features', space black balls, silver beams, purple crystals, and golden clusters,...... , at different speeds, as if agreed, together towards the stargate opened by the Dalk Zerg.

As if he had expected to suffer a strong blow from the other party, the red insect tide quickly gathered, and their limbs colluded, closely fitting together, forming blood-colored flesh walls in the blink of an eye, like the red insect tide of huge mountains piled up layer upon layer, resisting the front of the star gate, stretching for hundreds of thousands of kilometers.

"Boom", the silver ice crystal beam took the lead in bombarding the blood-colored flesh wall, running through the blood-colored flesh wall, but the blood-colored flesh wall seemed to have extremely strong vitality, constantly canceling out the energy of the ice crystal, and finally only let it advance more than 10,000 kilometers.

Immediately after, the golden light group attacked, smashing into the blood-colored flesh wall like thunder, exploding a large hole for thousands of kilometers, opening the way for the attack behind it.

…… ，

Under the continuous attacks, the 'Bloody Flesh Wall' in front of the stargate was only more than two kilometers thick, but there were also purple crystals with relatively slow speeds, and the busiest black space-time orb.

Compared to other swift attacks, the purple crystals only reached sub-light speeds, but its weight was unusually heavy, and the terrifying heat distorted the trajectory of its flight, bombarding the blood-colored flesh wall as if it were hitting paper, and piercing through them without much effort.

The blood-colored flesh wall with a thickness of more than 20,000 kilometers was pierced by it in a blink of an eye, and then, the purple crystals with amazing power pierced through the Star Gate directly, and continued to surpass the insect tide on the other side of the Star Gate.

At this moment, seven small spaceships with the central blue interstellar fortress accelerated together, turned into a ball of streamers, and before the black space-time sphere arrived, they all drilled into the stargate and disappeared in an instant.

Not long after, the slow black space-time sphere arrived at the location of the stargate, suddenly expanded, and burst out with a powerful suction, and together with the stargate, countless insect corpses in the entire galaxy were swarmed into it,......。

In the blink of an eye, the entire Pare Star Field seemed to have been ransacked, insect corpses, battleship wreckage, galloping asteroids, energy matter in the galaxy, energy rays,...... , all of which were absorbed by the suddenly expanding black hole,......。

The Xuanwu flagship command room, the command screen that monitors the entire interstellar battlefield, the picture is dark, and the power of the black space-time sphere bursts out, and even the monitoring beam is absorbed.

Everyone looked at the dimmed holographic screen, and they were all stunned, never expecting the result to be like this.

"That's how they killed the worms' nests?"

"I don't know what they're going to do!"

"Maybe the Dalk Zerg is not a threat to them, but something like a treasure, so they are so positive?"

"Incomprehensible, we are so far apart from them that it is difficult to understand their behavior!"

"Is that a black hole weapon?

……

The flagship command room, quiet for a while, 'bang', all the experts and professors talked excitedly, if they didn't see it with their own eyes, they would never believe this scene, those small spaceships were not afraid of the threat of the insect tide, but rushed into the other party's star gate, scrambling to kill the Dalk Zerg, which was the opposite of the result they expected.

"Xiaozhi, can't the tunnel monitor be activated?" Zhou Yu looked at Zhou Xiaozhi and asked with concern.

"Commander, due to the influence of space energy, the tunnel monitor cannot work for the time being!" Zhou Xiaozhi replied.

"For the time being, will this black hole not last for a long time?" Zhou Yu frowned and hurriedly asked.

"Commander, according to the data from the spectral telescope, its energy is rapidly declining, and in another 10 days, its activity should almost cease. Zhou Xiaozhi looked at Zhou Yu and reported.

"Commander, this is a weapon that simulates a black hole, and its power is not comparable to that of a black hole in progress, but this weapon is already very powerful, and it affects almost a tenth of the entire galaxy. Professor Smith looked at Zhou Yu and said with emotion.

"Well, can we imitate this black hole weapon?" Zhou Yu nodded, looking at Professor Smith expectantly and asked.

Hearing this, Professor Smith smiled bitterly and opened his mouth, wanting to say something, but finally hung his head helplessly and shook his head.

A real black hole is a special kind of celestial body in the universe, and the curvature of space-time inside is so great that even light cannot escape from its event horizon.

As a result, black holes cannot be directly observed, as is the case now, by indirectly knowing their existence and mass, observing their effects on other things, and by using the "edge information" of the heat and γ rays emitted by the object before it is sucked in.

The creation of a black hole is similar to that of a neutron star, where a star is preparing to perish, and its core rapidly shrinks and collapses under the influence of its own gravity, resulting in a powerful explosion. When all the matter in the core turns into neutrons, the contraction process immediately stops, and it is compressed into a dense star, which also compresses the space and time inside.

Because the mass of the star's core is so large that the contraction process goes on endlessly, even the repulsive force between the neutrons cannot stop it, and the neutrons themselves are crushed into powder by gravitational squeezing, leaving behind a matter of unimaginably high density, and the gravitational pull generated by the high quality makes it suck into any object that comes close to it.

……

How does the attack pattern of the small black spaceship simulate the principle of a black hole occur, what does it use as power, and how does it limit the stability of the 'black hole' in the beginning,...... There are so many complicated difficulties that Professor Smith can't even think of, let alone imitate this weapon.

"Is it possible that there is no such thing at all?" Zhou Yu asked with some disappointment looking at Professor Smith shaking his head without thinking about it.

Professor Yang Yi took a step forward and relieved Professor Smith and said, "Commander, this level of weapon should be designed by Mr. Zhou to make it possible, so we should transfer this precious battle record to your father as soon as possible!"

"Yes, Commander, the weapons used by these seven super civilization warships are all extraordinary, the red battleship should be emitting neutron star fragments, those silver crystal battleships should use negative energy weapons, the black battleships use black hole weapons, and the golden battleships use singularity weapons,...... They all have great research value, and if Mr. Zhou guides them, I believe they can gain a lot. Professor Smith looked at Zhou Yu with a look of shame and solemnly reminded.

Although it has not been seen for more than 200 years, Zhou Xing's prestige and his perverted research and development capabilities are still deeply rooted in the hearts of Professor Smith, Professor Yang Yi and others.

"Well, I see, but just wait until the tunnel detector is working, maybe the bugs won't get rid of it. Zhou Yu nodded, his eyes fixed on the command screen.

Hearing this, everyone's expressions were stunned, and they all looked nervously at the command screen.

If that black hole can't wipe out the remnants of the bugs, soon, the entire Paré Domain will soon be occupied by the Dalk Zerg, and then, it will seriously threaten the human civilization close to the Paré Domain.

The professors stopped talking, staring nervously at the surveillance data on the big screen, waiting for the end of the 'black hole' before they began their research.

At this time, it is actually the first time that human civilization has observed the existence of a 'black hole' at such a close distance, and although it is a fake 'black hole', it is still an excellent observation opportunity.

If it is replaced by a real black hole, the scientific and technological means of human civilization will not be able to intuitively observe its existence at such a close distance.

The real black hole has a vast impact, with a diameter of thousands of light-years or tens of thousands of light-years.

A black hole is not a real planet, but an almost empty region of the sky, where the density of matter is highest in the universe, and the center of the black hole has an extremely strong gravitational pull, and any object can only swim around the periphery of this center. Once you accidentally cross the boundary, you will be dragged by the strong gravitational pull towards the center, and eventually turn into powder and fall to the center of the black hole, which is an extremely terrifying area with an extremely wide radiation range.

Once the black hole is formed, then all the nearby galaxies will not be able to escape its swallowing, and then, its mass will continue to expand, and at the same time, as the mass rises, it will burst out with more powerful devouring force, frantically expanding its territory.

There are several ways in which supermassive black holes are formed, the most obvious is the formation of nearby stars by slow accretion, which continuously absorbs the stars, superimposes the mass of the black hole's center, and finally forms a supermassive black hole; another involves the atrophy of the air cloud into a relativistic star with a mass of more than hundreds of thousands of soles, which will begin to appear unstable due to the radial disturbance caused by the generation of positive and negative electron pairs in the core, and will shrink into a black hole directly without the formation of a supernova; the third method involves a high-density cluster that is collapsing in the core, and its negative heat capacity will cause the core to disperse at a relativistic velocityFinally, at the moment of the Big Bang, the primordial black hole was created from the external pressure.

"The center of the black hole is the most mysterious singularity in physics, that is, the point where time, space and all known laws of physics fall apart, but unfortunately we still can't look directly into their interior, otherwise, we can find a lot of magical events!" Professor Smith said with a regretful look at the surveillance screen.

"What a rare opportunity! Without adequate preparation, it was wasted!" Professor Yang Yi looked at the monitoring screen with a regretful expression.

The flagship command station Zhou Xiaozhi uses a spectral telescope, a space-time energy monitor,...... , and many other instruments, faithfully recording all the data of this artificial astronomical event and building a model, however, it is impossible to achieve a truly close intuitive observation.

Zhou Yu interrupted their research, turned his head to look at Zhou Xiaozhi, and asked in a low voice, "Xiaozhi, did the previous movement of the exploration ship feed back our signal?"

"Commander, Discovery did send a feedback signal to the outer universe, but the scene was too chaotic at the time for Ash to track down the receiver of the feedback signal. Zhou Xiaozhi nodded, looked at Zhou Yu and explained.

In the next second, the command screen changed, showing the picture of thousands of explorers shuttling out of the Par'e star field, and in the next second, many civilized warships followed the explorer, and they angrily wiped out the explorers in front of them one by one, but there were also many explorers who seemed to have achieved their goal, and after confirming something, they quickly drilled into the space-time tunnel and disappeared into the vast universe.

"Commander, a total of 17 Explorers have escaped the pursuit of these civilizations, and according to the wormhole overflow energy model they shuttle, it can be judged that they are not heading to the same destination, but are scurrying around like headless flies. Zhou Xiaozhi looked at Zhou Yu and reported.

"17 ships, can't you confirm that spaceship has confirmed our information?" Zhou Yu frowned, and continued to ask Zhou Xiaozhi.

"I haven't confirmed, their exploration mode is set by the Disorderly Law, so it's not easy for the enemy to capture the real target they want to search! Even I can't be sure what kind of data they're exploring. Zhou Xiaozhi shook his head in affirmation, and finally added: "Boss, you may have expected this a long time ago, so he protects us in this way!"

"It's deliberately set up by my father!" Zhou Yu's eyes lit up slightly, and he said with a look of nostalgia.

"Definitely! Otherwise, the Discovery will definitely chase us, and our tracks have already been discovered by those civilizations! The Discovery is supposed to belong to the disorderly exploration, even if it explores the target to be confirmed, it does not show it, but drives an unknown hidden program. Zhou Xiaozhi nodded vigorously and replied with no doubt.

"Well, Dad has always been very thoughtful, and I don't know what happened to them over there!" Zhou Yu nodded, confirming Zhou Xiaozhi's judgment, looking at the distant galaxy outside the space window, and said nostalgically.
