It took about two hours for the aliens to stop flipping through the computer.

"We can start communicating, time is pressing, time is running out, time flies, time is ...... Sorry wait a minute, I need to adjust it. ”

After a moment, the alien again said in an urgent tone: "Danger! ”

Just said the word danger, the alien didn't say anything, and after a while, looking at a group of people looking at him, the alien said again: "I'm sorry, I need to adjust it again." ”

After a moment again, the alien said in an unhurried and calm tone: "Hello, now we can start communicating, first of all, I want to explain, from ......"

It's stuck again.

Wang Hu said in a tentative tone: "You want to talk about those aliens? ”

"Yes, your naming of galaxies is very different from ours, I need to adjust it a little bit and explain it in a way that you can understand, please wait, okay."

After waiting for about a minute, the alien said again in a very calm tone: "I have a preliminary understanding of the earth civilization, according to your exploration of the universe, the hostile aliens come from the constellation Hydra, according to the Fransteide star nomenclature Liga Majoris 55 star system, 4600 light-years away from the earth. ”

Whether you understand it or not, just nod your head.

"According to Earth time, the 55 star system of Urus Liga began to explore outer space 11,000 years ago, and when we monitored that this civilization began to try to leave its home planet, their spacecraft speed could reach 1/40,000th of the speed of light, but soon, according to the division of speed by Earth civilization, they exceeded the third cosmic speed, reaching 1,400 percent of the speed of light."

Wang Hu looked at a young officer behind him, and the officer said quickly: "The first cosmic velocity is the speed around the earth, 7.9 kilometers per second, the second cosmic velocity is the velocity out of the earth's gravity, 11.2 kilometers per second, and the third cosmic velocity is the velocity away from the sun's gravity, 16.7 kilometers per second." ”

Wang Hu nodded, and then he said eagerly to the aliens, "Can I ask questions?" ”

"Yes."

"What is the speed of the Mega Snake aliens right now?"

"The speed of light is the universal unit of speed for advanced civilizations in the universe, and the civilization of the star system Hydra 55 is now the fastest speed, reaching 31 percent of the speed of light."

One-third of the speed of light, or almost 120,000 kilometers per second.

120,000 kilometers per second.

The fastest human spacecraft has not yet exceeded 16.7 kilometers per second.

Wang Hu was silent, everyone was silent, and after a while, Wang Hu said in a low voice: "What about you? How fast are you? ”

"The maximum speed of light is 65 percent, and the speed of spacecraft that is commonly used at present can reach 50 percent of the speed of light at the earliest."

More advanced than the Snake Major.

Immediately, smiles appeared on everyone's faces.

But Gao Yuan always remembered the danger that the alien said, but his status was too low, and it was not good to ask Wang Hu questions now.

Wang Hu thought for a moment and said, "So how are you going to deal with the aliens in Orochi?" Can you help us repel their aggression? ”

The alien was silent for a moment, and then he said in a calm tone: "I can't fight off the aliens in the star system of Hydra Liga 55, in order to get rid of the ...... Hydra"

Wang Hu said with some embarrassment: "Just call the big snake people?" Save ...... a little hassle."

"About five days ago Earth time, my spacecraft was discovered by the big snake people, and intercepted me, in outer space, they can't pose a threat to me, but after entering the earth's atmosphere, our speed is basically the same, in order to get rid of the interception of the big snake people, my spacecraft has crashed, so I can only help the earth humans, and I can't directly help you repel the invasion of the big snake people."

The heart is cold, so it is a long silence.

Wang Hu sighed and said in a low voice, "You guys...... Aren't there any more people coming? May I ask what planet you are from, and what kind of civilization is your civilization? ”

This time the aliens were silent.

Wang Hu hurriedly said: "It's inconvenient to answer, just forget it, just because I didn't ask." ”

"Our civilization has been destroyed, our home star is from the Milky Way, a planetary system 6,300 light years away from the Earth, about 5,000 years ago Earth time, our home star has been destroyed by a supernova explosion, the Earth observed and recorded this supernova explosion, and in May of the first year, the morning rose in the east, and the sky was watched. The day is as white as it is too white, and the horns are out, and the color is red and white. ”

Everyone nodded together, and only the history professor shouted, "I know, I know!" It is recorded in the book "Song Hui Yao". ”

The alien continued to say calmly: "At the time of the demise of the home planet, we were already capable of large-scale interstellar migration, our new home was in the Milky Way, 1,800 light-years away from Earth, and Earth did not record our planetary system, and that was because, when you began to have enough ability to see our planetary system, our planetary system perished again. ”

Everyone was sluggish together, perishing twice in a row?

"Why did it perish?"

"War. Civil war. ”

The alien didn't say much, and Gao Yuan also let out a regretful and regretful sigh together.

The point is, no one came to save it......

"Unlike the catastrophe caused by the first supernova explosion, the second catastrophe, the main body of our civilization was not able to escape, so our civilization has been functionally extinct, leaving only about 10,000 remnants in all corners of the universe, just like your astronauts, drifting in the universe, but now, the Great Snake People have become our common threat, because after occupying the Earth, the next target of the Great Snake People will be our new home."

What do you say?

There's really nothing to say.

Gao Yuan pretended to have the courage to interject, "Is it possible for us to defeat the Great Snake Man?" ”

"Yes."

Gao Yuan immediately said: "How likely is it?" ”

The aliens were silent, and at this time, Gao Yuan couldn't help but say, "Is it impossible to defeat them at all......"

"There needs to be a precondition for this question, that is, you are asking about the Great Snake People Expedition, or the main body of civilization of the Great Snake People."

"Expedition?"

The alien said very calmly: "The Great Snake Man who came to the Earth at present left the home planet 7,500 years ago in Earth time, and the speed is twenty-two percent of the speed of light, and now, the speed of the Great Snake Man's expedition spacecraft has reached thirty-one percent, occupying three habitable planets, and the population has been uncountable." ”

An officer said suspiciously: "This time is not right, right?" ”

The alien still said calmly: "Wormhole, in the astrophysics of the earth, the description of the wormhole is basically correct, this expedition is from the third planet of the Great Snake Man, five thousand and five hundred light years away from here, but there is a wormhole, so they only need about two thousand years of Earth time to reach the Earth from the third planet of the Great Snake Man, and our planet to the earth does not have a wormhole, so our distance is closer, faster, but it takes longer." ”

It's messed up, it's all messed up, when the concepts of time, distance, and space are related to wormholes, Gao Yuan immediately gave up the relationship between time and distance in the conversion, he didn't have that brain.

At this time, Wang Hu said in a low voice: "Are you saying that it is just an expedition team that has come to invade us now?" ”

"Yes, it's just an expedition, a mother ship of two basic units, used to explore the habitable planet that has been discovered, if it is confirmed that it is suitable for the survival of the Great Snake Man, then occupy this planet, and if there is a high civilization on this planet, then destroy the civilization of this planet first."

After saying that, the alien was silent for a moment, and then he said loudly: "According to our ...... The earth does not have this word, it cannot be accurately expressed, it can be called a cosmic observation device, according to the discovery of our cosmic observation device, the main civilization of the Great Snake people has set off from the home planet, and according to their speed, and the impulse that can be used on the way, they will arrive in 320 years after Earth time. ”

Wang Hu rubbed his chin with his hand, and then he said very bitterly: "Flying for thousands of years, just to occupy our planet?" Where is the earth good......"

"In the universe, every planet suitable for the survival of your own civilization is incomparably precious, and it is your greatest misfortune to belong to carbon-based creatures that are highly similar to the Great Snake People."

Wang Hu was silent for a moment, and then he said to the alien: "What about you? Are you also carbon-based life? Are you the essence of what you are now? Or a spacesuit or something? ”

"This is a collection of spacesuits, personal vehicles, escape pods, tool suits for communicating with lower civilizations, protective layers, and many other functions...... Shell, please let me find a suitable word, I found it, to use a word that is easy for you to understand, this is a mecha. ”
