To be precise, what Yu Yifeng observed was a huge, moon-sized dot!

There are more than a dozen small dots around it, and according to the calculations of the gravitational wave telescope, each dot is about 150 kilometers - 200 kilometers in diameter!

"Is there such a strange celestial body?" Yu Yifeng was very puzzled, and he subconsciously rubbed his eyes.

The distance of 0.6 light years is already very far away for humans, even out of reach.

Launched in 1977, Voyager 1 is the farthest man-made vehicle from Earth, at a distance of about 17 billion kilometers from the Sun......

And one light year, about 9,460 billion kilometers.

According to this calculation, the maximum distance that humans have explored so far is ...... 0.002 light years. It's really hard to imagine, a light year away.

The universe, in contrast to this distance, appears even wider.

The position of 0.6 light years is in the category of the Oort Nebula, and human exploration of this nebula can be said to be almost zero. Therefore, the appearance of a planet the size of the moon in that area should not be too much of a problem, at least not in the category of being particularly surprising. Maybe the planet itself exists and hasn't been discovered?

But Yu Yifeng felt a little weird. Are the dozen or so small dots around them all meteorites, and ...... Lined up? It's too neat, too regular, right?

Yu Yifeng frowned, calculated its speed with his hand, and when he saw the result of jumping out, his head "boomed" and dizzy, as if he couldn't believe it, and he was still stunned after a long time.

His hands trembled slightly, and he repeated the calculation again, and it was still the same result!

"What is this?" He immediately shouted, this kind of simple question, he is not wrong, there is definitely something wrong with this dot!

Hearing Yu Yifeng's exclamation, a group of scientists who were contemplating stood up one after another and walked to Yu Yifeng's side.

When they saw Yu Yifeng's calculation results, they stood still one by one, as if they had witnessed an incredible scene......

Matteon!

A bunch of sub-light-speed balls are flying into the solar system!

It's definitely not a star, it's ...... Spaceships, absolutely huge - spaceships! This is an incomparably powerful fleet, the smallest, also a hundred and fifty kilometers, comparable to the spaceship of the green light civilization!

"What is this?"

"What's the situation?!"

Some scientists exclaimed, others shouted, but apart from this explanation, no star can reach the level of sub-light speed!

Although he was still in a very shocked state in his mind, Yu Yifeng immediately issued a notice of an emergency meeting. At the same time, he asked Thomson and other astronomers to keep a close eye on the area and try to find the super-large fleet in other ways.

……

"Ladies and gentlemen, this time the situation is very urgent, and we discovered it by accident. The fleet is moving at about 0.6 times the speed of light, and the gravitational wave telescope, although it was spotted 0.6 light-years away, is ...... The propagation speed of gravitational waves is also the speed of light, and the information is lagging, so to speak, this is a picture from 0.6 years ago! ”

Yu Yifeng's face was pale, and the observation image was played on the screen, "The largest main ship in the middle, the volume is comparable to the moon, and the diameter is about 3,000 kilometers!" ”

"There are 12 smaller ships, each with a diameter of 150-200 kilometers!"

At the end of the sentence, the anxiety in his heart was almost uncontrollable, and he even slammed his fist on the table.

"Total ...... 13 ships! ”

A supership the size of the moon! This is almost something that only exists in science fiction, but now it is alive in front of people, and the shock is beyond words...... How much time does it take to transform a planet into a spaceship, and how much industrial power does it take?

This oppressive feeling is the pinnacle of human technology that is unimaginable at present!

Infinitesimal!

Human beings are really too small......

Yu Yifeng didn't know what this fleet meant. I don't know what its purpose is in running menacingly into the solar system...... All he knew was that it was never a good thing for humans!

There's a green-light civilization in front, and there's a fleet in the back? What's going on?

Sitting at the bottom of the meeting were the main persons in charge of the major factories, the major scientists and the relevant parliamentarians, and a kind of Taishan-like pressure appeared in the hearts of everyone, pressing them out of breath.

All of them were pale and anxious.

Fortunately...... No crashes!

This is also the most gratifying point for Yu Yifeng. Over the years, mankind has experienced a bit more crises, and its ability to bear it seems to be gradually rising, and both parliamentarians and scientists are just thinking in silence one by one, and will not directly cry out in despair.

This is much better than two years ago, when people were still on the moon and the Noah program had not yet been implemented. After hearing that the moon was about to be destroyed, the same group of people almost collapsed, relying entirely on Yi Feng's continuous roar and roar, and barely pulled it back.

Yu Yifeng will always remember that scene, as if the sky had fallen, and everyone was so desperate and sad......

But now, this feeling has reappeared, but differently, and this is the progress of all humanity! It's always good to be able to think, and both anxiety and anger are more useful than despair.

"I have to say that any warship is not a ...... that we humans can compete with" As the leader of civilization, when he said this, Yu Yifeng suddenly felt a burst of sadness, or a kind of grief and indignation!

"We observed them in advance, and we had to figure it out early!"

One by one, the brows of the people furrowed. In the face of such a powerful civilization, human beings are really too humble and too small.

The dark universe, the boundless universe, contains countless crises, and any wind and grass can make all mankind perish!

Technology, technology! We need stronger technology, even if it's ...... Do whatever it takes!

He coughed lightly and said in a serious tone, "According to our calculations, that fleet is still 0.24 light-years away from Pluto...... That is, in another five months, you will be able to reach the position of Pluto! ”

"We have five months to go."

With that, he sat down and tried to think.

It seems strange...... It's just that there is a green light civilization that has taken refuge, why is there a huge fleet? Is this the ghost of the Green Light Civilization, or is it something else? Don't...... Continue to plan with camouflage?

If the ruined spaceship of the Green Light Civilization can be frightened by humans, then ...... This huge fleet is absolutely impossible to simply bluff.

What to do? What to do?

At this time, Professor Thomson also came with even more bad news: "We tried various methods, but we couldn't observe it at all, and the other side seemed to maintain a state of radio silence...... Moreover, there is hardly any reflected light and heat radiation. With our radio telescopes, there's no way to see it! ”

"No,...... Still no, we used a radio interferometer and still can't see it, only a gravitational wave telescope! ”

Yu Yifeng frowned when he heard this, he was a little depressed, but also a little happy. Fortunately, mankind has gravitational wave telescopes that surpass several technological levels, otherwise...... Only when the other party gets close will you know that this is too dangerous!
