In the darkness of space, a human curvature spaceship is slowly heading towards the Earth's spaceport.

In a living cabin inside, a group of strange-looking humanoid creatures are gathering together in twos and threes, chatting quietly, and the atmosphere is a little depressing.

Their skin is grayish-yellow, hairless, and looks rather rough, with four hands on their upper body, three fingers on their palms, and two bulges like humps on the top of their heads, generally about two and a half meters tall, making them look like little giants.

They are an extraterrestrial civilization from the two-brained people named by humans more than two hundred light-years away from Earth.

In the process of evolution, their brains split into two relatively independent but interconnected brains, each of which is controlled by a different brain, and this unique physiological structure gives them an innate ability to be distracted.

Among this group of two-brained people, there are high-level people in their government, giants in various scientific fields, experts in intelligence gathering, and think tanks in government decision-making, which can be described as an elite gathering, but since they came here, except for a few limited areas where they can move freely, the rest of the positions are difficult to move.

There is no superfluous packaging in this living cabin at all, it is basically the original, for example, the ground is only a layer of frosted metal with anti-slip treatment, and the walls are also metal, except for a light wall above the head that does not show any technology and a group of intelligent robots that specialize in serving or monitoring them, there are basically not many traces of that highly civilized technology here.

But even a few sporadic discoveries made them feel powerless.

"The gap is so big that maybe we won't be able to build such a spaceship for thousands of years!" An expert in the field of materials gently rubbed the smooth mirror-like armor layer on the outside of the living chamber with the palm of his hand, and the other three hands danced and sighed.

Before he came, he had secretly brought a knife, which was no longer than a finger, made of the hardest material in their civilization, and could not even be industrially produced, but could only be prepared on a small scale in the laboratory.

But in the past two years, not to mention the extremely smooth walls, even if the ground is frosted metal, until the blade is smoothed, he has not scratched a single scratch.

"After all, this is a curvature spaceship of a high civilization, which is unimaginable to us, and without powerful material technology, it simply cannot withstand the impact of light pressure." A physicist shook his head, then said, "I'm more curious about the technical principle of their curvature engine, if only I could take a look." ”

"It's impossible, they're never going to let go of military technology." A high-ranking government member said in despair: "And it's useless for us to get it, after this negotiation, we will be strictly forbidden to develop military technology, and the human fleet will be permanently stationed in our galaxy." ”

The atmosphere was suddenly depressing.

This time it is not so much to negotiate, but to sign an unconditional surrender treaty, to completely surrender to this high civilization, there is no room for bargaining at all, in fact, up to now they have no trace of resistance, civilization has reached the choice of life and death, those who go along prosper and those who rebel die!

Five years ago, two human warships appeared in their system.

The humans deciphered the Two-Brained Humans' language and sent them a channel-wide advisory to surrender, causing a great panic.

A day later, the persuasion was strongly rejected by the previous leader.

So, the war began, the technology of the two-brained people has developed to the intragalactic civilization, and it is one step away from the interstellar civilization, under the accumulation of hundreds of years, the number of space warships is not a few, when the two-brained people organized all the hundreds of warships, and rushed towards the human warships.

In just an instant, hundreds of warships lit up with a ball of light at the same moment, a dazzling light, and even hundreds of suns appeared in the dark space, and then, countless defensive forces in space were also destroyed one after another, and they were useless.

In just ten days, the human warship approached the planet of life, and under the tremendous pressure of the destruction of the country and the extinction of the species, the leader of the hardliners was ousted, and the new leader immediately announced his surrender to mankind, and the war was completely over.

……

The spaceship gradually flew into the spaceport, and accompanied by a human officer, all the two-brained people walked into the port, and then transferred to the air-to-ground vehicle and rushed to Earth.

Compared with the rugged and rigid habitation cabin of the military spaceship, the air-to-ground vehicle undoubtedly looks countless times more luxurious, and all kinds of advanced technology make people feel inexplicably awe-inspired.

"My lord from a powerful civilization, is there a place where you can see the scenery outside?" A two-brained man cautiously asked the accompanying officer, who had been trained in human language before coming, and did not interfere with communication except for a slight change in accent and language organization.

The officer nodded expressionlessly, and then said, "Zhi Brain, open the panoramic virtual reality!" ”

"Understood!"

After a soft female voice, all the walls of the aircraft suddenly became transparent, and the surroundings immediately became dark, and everyone seemed to be sitting in the starry sky.

"This ...... It's incredible. A two-brained scientist tentatively stood up cautiously, and if he hadn't felt the solid texture under his feet, he would have thought he had really come to space.

They also have virtual reality technology, but it is so real that it is difficult to distinguish between falsehoods and is really shocking.

"Look back!" At this time, a two-brained man exclaimed.

Everyone immediately turned their heads to look, just a glance, and subconsciously held their breath.

"Oh my God!"

"It's incredible!"

This is a huge unimaginably unimaginably beehive-shaped military port, with tens of thousands of warships, fixed by huge metal fixing pliers, like rows of soldiers on standby, neatly arranged.

Thinking that any spaceship here can easily destroy their civilization, the body is as if it has been electrified, numb, and almost prostrate on the ground, the power of this advanced civilization technology makes people feel heartfelt awe,

Before they could sigh for long, another behemoth came into view, at first, everyone thought it was a moon about to rush to the planet, but as they got closer and closer, until they saw its silvery smooth surface, and it was absolutely impossible to be a perfect circle of natural formation, everyone was a little uneasy.

"Honorable lord, can you tell us what this thing is?" A high-ranking member of the two-brained civilized government asked with a trembling voice.

The young officer showed a faint smile and said with a hint of pride: "This is a planetary fortress, five hundred kilometers in diameter, one-twentieth the mass of your home planet, and it can travel at fifty times the speed of light for six thousand years as long as it is refilled with antimatter fuel once. ”

Fifty times the speed of light multiplied by six thousand years is 300,000 light years.

After hearing this, everyone subconsciously gasped, and couldn't help but tremble slightly, knowing that the entire galaxy is only about 100,000 light years, and this huge planetary fortress like a satellite can fly away from the galaxy.

After the young officer said a word, he stopped talking, although his words were not deceptive, to some extent, they were exaggerated, the interior of the planetary fortress was extremely large, and even if the necessary equipment was removed, at least a third of the area could be stocked with antimatter fuel. However, even for today's humans, it would take all the antimatter output of the Dyson sphere in a hundred years to fill it.

As for the current antimatter reserves in the fortress of this planet,
