[At the beginning of the 24th year of the era of crisis, the cornerstone empire]

Humans in the solar system are tearing down some of the facilities left behind before the "negative civilization". I saw a beautiful female soldier in military uniform glue a bomb to a building, and then slowly sat down on a flying balloon to reach a far enough place, and pressed the explosion button on the balloon fiercely, at this time she felt comfortable inside. After a strong flash of light, the last of the "negative civilized" buildings were blown up.

The wreckage of the building was piled up below, and even the previous uniform colors had become messy, with some residue from the high-energy chemical explosion attached to it, and the pillars of the base were coated with a layer of yellow powder that was difficult to erase. The other buildings were torn apart, and their heads were in different places. The base that the human rebels were proud of before is now stained with people's spit. People seem to be unleashing their hatred for the rebels on the ruins.

Some people proposed to take the rebel spaceships in the base to the Academy of Science and Technology for research to see if these alien spaceships had some unknown black technology; There are also people who think that it should be put in a museum for people to see. But these suggestions were rejected by the local government, which they considered to be the stuff of human rebels, the dirtiest thing, the ugliest symbol, and should not be put in an admirable museum, a formidable science and technology institute.

The government sent civil servants and other cadres to take the rebel spacecraft to the incineration plant and destroy them. In the incineration room, there are some strange structures with triangular surfaces, and after a strong laser rain, all the spaceships are vaporized, and these waste gases are discharged into space through ground-to-air pipelines.

Anyone who has watched the news knows that the news media is reporting like crazy about it. The host is telling this heartwarming event in an impassioned tone.

"Rejoice, I, the inhabitants of Mars, destroy the base of the evil of 'negative civilization'......" is the cry of the news.

“…… This destruction operation marks the total liberation of Mars......" is the text of the information release.

"Cheers, celebrate the liberation of Mars!" Such a noise was heard from a building in a residential area.

……

When humanity celebrates with great enthusiasm, a thousand light-years away.

In the same galaxy, the interstellar war is nearing its end, and the firepower of the Cornerstone Empire is significantly inferior to that of the enemy army known as "Spectre", with starlight dotting the entire territory, clouds of gamma rays churning each other, and rain lines composed of high-energy particle beams splashing endlessly. The faint starlight of the night studded with bleak starlight looks bleak. The wind of war hurriedly swept across the stars, setting off a wave of destruction, as if the waves on the sea were constantly curling, constantly slapping the sea surface heavily, splashing a large white splash. Then another big wave appeared, and began to roll and lap again......

Previously, around the beginning of the 16th century, the Ghost Army appeared next to Betelgeuse, and the Cornerstone Empire also discovered it, a lightspeed particle emitted from the mechanical planet fortress, killing Betelgeuse, causing the radiation within Betelgeuse to burst out directly. The cornerstone empire intended to use the violent explosion of the red giant star to destroy the Spectre's fleet, and it was so successful that the Spectre's fleet was reduced to two-thirds of its original size. After that, the ghost went into hiding, but in these fifty years (a year in the human algorithm), the "ghost" reappeared and "played" "hide and seek" with the cornerstone empire. Today, it's the turn of the "Ghost" to catch the cornerstone civilization, and the chase is going on a thousand light-years away from the solar system......

In the main Sene, the leader of the human rebel "negative civilization" is standing in the temple, which is specially used by the cornerstone empire to welcome the dignitaries returning from the front. But this time, it welcomed a life form from another civilization.

The leader had come here ten days ago, walking through the caverns of time and space. At this time, the hall was suspended in the air by the magnetic levitation effect, like a mirage faintly in the clouds. The hall is decorated with objects that are difficult for the leader to recognize, showing the glorious culture of this civilization, shining brightly. He looked at the floor of the hall in amazement, although he had lived here for ten days, the leader still felt strange and unexpected. It can be seen in several delicate crafts: an incredible process.

"The universe is very big, the fate is very deep, and we meet again." In the center of the hall, there is a suspended sphere, which emits a faint white light, which has no texture to the touch, but the color is very harmonious. The leader guesses that it is an intelligent program of the Cornerstone Empire. The sound seemed to come from within the sphere, peaceful and neutral, and it was impossible to distinguish between male and female.

"Are you ......," said the leader eagerly, already having too many questions in his heart.

"I am the Cornerstone Empire."

"Who is the Cornerstone Empire?"

“…… Sorry for our late reception, friend of the outsiders. I've been busy on the front lines before. "However, I have seen you, and I saved you in the Martian War." ”

"Seen?"

"Yes." The sphere replied simply, "It's on Pluto, before you made the tachyon to hit the Sun, and your base was still in the inaccessible city of Pluto. And I also know that your strike weapons are built on Ceres. And your tachyon weapon was introduced by a fleet of strange visitors. ”

"This ...... It turned out to be you. The chief said excitedly, "It is the Lord, the Lord, my Lord......"

"I'm sure you remember what happened on Pluto, when ......"

Thoughts of memories drifted to the day of the 20th year of the Age of Crisis, on Pluto, where the rebels' base sits. The cold night was solemn, the spots were white and black, and a few stars were stingily shining, slightly dim.

The base is built on the inhospitable ground of Pluto, which is inaccessible, and on Pluto, the only human traces left are the stone monuments located on the North and South poles. The words on the stele are almost exhausted, and they have been weathered by the years.

[Pluto lot.]

Era of Crisis 16 years】

It wasn't until 20 years of the crisis that someone finally came, not strictly speaking, they were "people", they were shameless traitors among the human race. But he is also the first and only human to see an extraterrestrial civilization with his own eyes.

The glimmer of the miserly star suddenly disappeared, and even the starry sky was gone, as if covered by a large hand.

"Chief, what's going on?"

"This ......"

Obscuring the stars was a huge spaceship that obscured the entire sky, followed by small discs flying out of the huge mothership, making it difficult to see. Let the people on the ground have a feeling of oppression. People looked at the skylight and didn't know what was going on.

"Judging by the images coming back from the reflected waves, it's a huge similar ......, and hey—I can't find a metaphor. In short, the underside is an irregular circle. ”

"Either way, all nodes are ready for battle."

On the buildings of the base, a turret was raised, many sliding doors on the ground were opened, and some weapons were raised inside, all aimed at detecting the return of the reflected waves.

As everyone knows, they are about to encounter an alien civilization.

"Hello, don't panic. We have scanned the entire contents of your base, identified all information about your civilization, and learned your language. We're an expedition from afar, and we're passing through your world unintentionally, sorry. "The strange object sent a signal through electromagnetic waves.

"We don't want to start a war. The purpose of our trip was to obtain physiological resources. I wanted to collect it directly, but I met you. I'm glad to meet another world. It said, "You can call us that...... In your dictionary, we've found a word that makes sense to sum up your name - 'Cornerstone Empire'"

"So why are you staying on this planet?" The leader of the "negative civilization" asked.

"Can you make a deal?"

"Let's hear it."

"We're trading our second-class technology for some of your resources, like some of your food."

"But we're carbon-based beings, and we may have different physiology than you." The biologists among the people say, "Our distinction may be distinguished by phylum and boundary." ”

"No, we've traveled to a lot of stars, we've lived in a lot of environments, carbon-based, silicon-based, and so on." The Cornerstone Empire said, "Give your granary." ”

"What technology do you have?"

"There is ......"

——

After a while, the leader retracted his thoughts, and suddenly the whole person seemed to be back in the palace, but in fact he did not go away.

"You really are the Lord."

"Hey, the world has changed, and the Lord is gone."

"Let's go?"

“yes.” The Lord replied at length.

The main plug is outside, with a radius of fifty astronomical units, surrounded by a deep layer of black, which is darker than the background of the eternal night in space. There was nothing there, so it was so dark, there was not even light.

The cornerstone empire can't resist the powerful attack of the "ghost", so it can only use the method of escaping, and the empire can create a space distortion that can break through the cosmic space, and then the "hole" left behind after these breaks is not accessible to any matter or energy, after all, space is the origin of all things. Make a circle in the shape of the "hole", encircle the cornerstone empire, with the cornerstone empire as the center of the circle, with an average radius of fifty astronomical units, so that the cornerstone empire is isolated from the space outside the circle. Since it is impossible for anything to enter the "Void", and the Cornerstone Empire is surrounded by the Void, it is out of the Great Universe. This is the escape plan of the Cornerstone Empire. In the physics of the cornerstone empire, this "void" is called a "space vacuum".

If you want to find a figurative analogy, it is: draw a circle on a piece of white paper, and then prick the circle little by little with a needle, until each hole is connected, and the circle gap is formed like the circle drawn, and the area inside that was originally part of the paper is separated from the paper. It's a figurative metaphor.

In the future, when other civilizations come to observe, they will only sense an incomparably black irregular circular space, but they will not see an empire inside. Perhaps this "void" has become another great unsolved mystery of the universe.

At this time, the "space vacuum" has not yet formed, because the cornerstone empire still has something to do.

"We have decided to transmit all our technologies, cultures, and theories to your community, and you will be our last spark in the universe and pass on our culture. You can do anything with our culture and knowledge, but the ultimate power of technology is mine, I am in the small universe, hoping for you. ”

"Alright, goodbye." The Cornerstone Empire has opened a space-time cavity, "Now, go." (You have to go home quickly, or you won't be able to go back after you leave.) Finally, thank you. Hats off to the 'negative civilization' community. ”

"It's not a nice name. Another one. The leader said with a grin.

At this time, the leader of the palace was not alone, but all the high-ranking officials and generals of the "negative civilization" came to say goodbye together.

“…… Tinder, let's go. ”
