After about two hours, the alien stopped browsing the computer.

"We can start communicating now. Time is running out. Time flies. Time flies. I'm sorry. Please wait a moment. I need to adjust."

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

After saying the word "danger", the alien said nothing. After a while, looking at a group of people looking at him, the alien said again: "I'm sorry, I need to adjust again."

After another moment, the alien spoke in a calm and leisurely tone: "Hello, we can start communicating now. First, I want to explain that I am from..."

Stuck again.

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

"Yes, your naming of galaxies is very different from ours. I need to make some adjustments and explain it in a way you can understand. Please wait a moment, that's it."

After waiting for about a minute, the alien again said in a very calm tone: "I already have a preliminary understanding of the earth's civilization. According to your exploration of the universe, the hostile aliens come from the constellation Serpent. According to the star Flamsteed,

The named 55 Serpentis planetary system is located 4,600 light-years away from Earth.”

Regardless of whether you understand or not, just nod your head.

"According to Earth time, the 55 Serpentis star system began exploring outer space 11,000 years ago. When we monitored that this civilization began to try to leave its mother star, their spacecraft could reach 40,000 times the speed of light.

One percent, but very quickly, according to the classification of speed by earth civilization, they exceeded the speed of the third universe and reached one thousand four hundredth of the speed of light."

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

It is the speed away from the sun’s gravity, 16.7 kilometers per second.”

Wang Hu nodded, and then he said eagerly to the alien: "Can I ask a question?"

"able."

"What is the speed of the Serpent alien now?"

"The speed of light is the universal speed measurement unit for advanced civilizations in the universe. The current fastest speed of the planetary system civilization of 55 Serpenis is 31% of the speed of light."

One-third of the speed of light is approximately 120,000 kilometers per second.

One hundred and twenty thousand kilometers per second.

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

Wang Hu was silent, and everyone was silent. After a while, Wang Hu whispered: "What about you? How fast are you?"

"Sixty-five percent of the maximum speed of light. The speed of currently commonly used spacecraft can reach as fast as 50 percent of the speed of light."

More advanced than the Serpents.

Smiles immediately appeared on everyone's faces.

But Gao Yuan always remembered the danger the alien said, but his status was too low to ask questions beyond Wang Hu.

Wang Hu thought for a moment and said: "So how do you plan to deal with the aliens in the Serpent Constellation? Can you help us repel their invasion?"

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

Wang Hu said with some embarrassment: "Can we just call him Orochi? It will save trouble..."

"About five days ago in Earth time, my spacecraft was discovered by the Orochi and intercepted me. In outer space, they could not pose a threat to me, but after entering the Earth's atmosphere, our speeds were basically the same. In order to get rid of the Orochi,

interception, my spacecraft has crashed, so I can only provide help to the humans on Earth, but cannot directly help you repel the invasion of the Orochi."

My heart felt cold, so I was silent for a long time.

Wang Hu breathed a sigh of relief and whispered: "Don't you...have more people coming? Can I ask, which planet you are from, and what kind of civilization is yours?"

This time the alien was silent.

Wang Hu quickly said: "If it's not convenient to answer, forget it. Just pretend I didn't ask."

"Our civilization has been destroyed. Our home star comes from the Milky Way, a planetary system 6,300 light-years away from the earth. About five thousand years ago on Earth, our home star was destroyed by a supernova explosion. Earth observations and records

This supernova explosion occurred in May of the first year of Zhihe. It came out of the east in the morning and guarded Tianguan. The day was as white as the sky, with awns and horns coming out in all directions, and the color was red and white."

Everyone nodded together, only the history professor said loudly: "I know, I know! It is recorded in the book "Song Huiyao"."

The alien continued calmly: "When the mother star died, we were already capable of large-scale interstellar immigration. Our new home is in the Milky Way, 1,800 light-years away from the earth. The earth has not recorded our planet.

system, that’s because when you began to have enough ability to see our planetary system, our planetary system died once again.”

Everyone was sluggish together and perished twice in a row?

"Why did it perish?"

"War. Civil war."

The alien said no more, Gao Yuan and the others also let out a sigh of pity and regret.

The key is, no one is coming to save you...

"Unlike the disaster caused by the first supernova explosion, in the second disaster, the main body of our civilization failed to escape, so our civilization has been functionally extinct, leaving only about 10,000 people remaining in every corner of the universe, just like

Like your astronauts, they are wandering in the universe, but now, the Orochi have become our common threat, because after occupying the earth, the Orochi's next target will be our new home."

What can I say?

I really have nothing to say.

Gao Yuan pretended to be brave and interjected: "Is it possible for us to defeat the Orochi?"

"have."

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

The aliens were silent. At this time, Gao Yuan couldn't help but said: "Is it impossible to defeat them..."

"This question requires a precondition, that is, are you asking about the Orochi expedition team or the main body of the Orochi civilization."

"Expedition team?"

The alien said very calmly: "The Orochi who are currently on Earth left their home star 7,500 years ago, at a speed of 22% of the speed of light. Now, the speed of the Orochi's expedition spacecraft is

It has reached 31%, occupying three habitable planets, and the population has become uncountable."

An officer asked doubtfully: "Isn't this the right time?"

The alien still said calmly: "Wormholes, the description of wormholes in Earth's astrophysics is basically correct. This expedition set out from the third planet of Orochi, which is 5,500 light years away.

But there are wormholes, so they only need about two thousand years of Earth time to reach the earth from the third planet of Orochi. However, there is no wormhole from our planet to the earth, so our distance is closer and the speed is faster, but it takes more time

But longer.”

It was messed up, it was all messed up. When the concepts of time, distance, and space were related to wormholes, Gao Yuan immediately gave up on converting the relationship between time and distance. He didn't have the brains.

At this time, Wang Hu whispered: "You mean, it's just an expedition team that invades us now?"

"Yes, it is just an expedition team, a mother ship with two basic units, used to explore the habitable planet discovered. If it is confirmed that it is suitable for the Orochi people to survive, then occupy this planet. If there is an advanced civilization on this planet, then first

Destroy civilization on this planet."

After finishing speaking, the alien was silent for a moment, and then he loudly said: "According to our... The earth does not have this vocabulary, which cannot be expressed accurately. It can be called a cosmic observation equipment. According to the findings of our cosmic observation equipment, the Orochi Man

The main civilization has already set off from the mother star. According to their speed and the impulses they can use on the way, they will arrive in 320 years of earth time."

Wang Hu rubbed his chin with his hand, and then he said bitterly: "Is it true that you have been flying for thousands of years just to occupy our planet? Where is the earth better..."

"In the universe, every planet suitable for the survival of one's own civilization is extremely precious. Carbon-based creatures that are highly similar to the Orochi people are your greatest misfortune."

Wang Hu was silent for a moment, and then he said to the aliens: "What about you? Are you also carbon-based life forms? Is your current form a true body? Or is it a space suit or other equipment?"

"This is a space suit, a personal aircraft, an escape capsule, a tool suit for communicating with lower civilizations, a protective layer, and other functions... Shell, please let me find a suitable word, I found it, use one of yours
