This is the human branch represented by Captan, the third planet, and the Golden Sun.

The climate on the planet's surface is always so cold and harsh. At temperatures above 180 degrees below zero, water vapor and carbon dioxide freeze into a white solid. In the north and south poles of this planet, even lakes composed of methane, ethane and other organic matter can be found. These simple organic minerals are undoubtedly quite beneficial to the development of mankind.

A total of 30 million human colonists live in underground cities under the planet, a depth of one kilometer.

The fire of nuclear fusion brings endless energy and is also the greatest courage for human interstellar colonization.

The old captain Xu Peng narrowed his eyes and looked at the starry sky in the distance through a thick layer of glass. Because this planet is too cold, the atmosphere is frozen into solid, so the air is thin and the stars in the distance are extremely clear.

Xu Peng is deciding which one is the sun and which one is Glitzer 581.

The sun at this distance can be seen with the naked eye, but Glitzer 581... is too dim and has to use an astronomical telescope to see a vague shadow.

The old captain Xu Peng retreated to the second line ten years ago due to his energy decline.

However, the old man is always too idle to stay. He has become a volunteer worker at the observatory. He takes children to see the stars in his spare time and teaches them how to use telescopes. It feels quite good to educate the next generation.

However, there are no children coming to the observatory today. Maybe the final exam is coming soon and the students are very nervous about reviewing... The education of the entire civilization is still very strict, and everyone must study hard.

drop!

It's almost five o'clock, and it's time to get off work.

Anyway, it’s boring to be idle. Xu Peng put on his own power armor and walked into the vacuum chamber not far away.

hiss!

The air pump slowly pulled out the air in the vacuum chamber. Immediately afterwards, he opened the door of the air pressure gate and made a heavy "click". Fortunately, the gas in the room had almost been pumped out, and not much air was leaked out.

The electronic prompt in the security gate sounded, "Hello, General Xu Peng, Class A authority."

"Please be careful when going out and pay attention to outdoor safety. The current outdoor temperature is minus 182 degrees Celsius."

Xu Peng walked along the glass tunnel to an observation deck.

From this position, you can see a space elevator of tens of thousands of kilometers at a height of time by looking up. If you use the telescope function provided by the Power Armor, you can clearly see that the centrifugal wheel rotating above is rotating, various transport spacecraft are coming and going, and a...

Huge mothership!

Yes, interstellar expedition must have a super mothership so that it can accommodate more people.

And more population means more productivity and maintenance capabilities. Especially the latter maintenance capabilities, without maintenance in the starry sky, a warship composed of an army cannot span a distance of several light years.

"It would be great if humans could live longer...then there would be no need for long-term rotation of hibernation, the population would be smaller, and the spacecraft could be built smaller."

For this interstellar voyage, related interstellar astronaut training is also underway, and has been going on for more than 20 years.

"In another three to five years, the entire Star Fleet will be built...it's time to set off."

Thinking of this, Xu Peng couldn't help but be ambitious about it.

Although this is a story of a young man, an old horse is in the stable and has ambitions for thousands of miles. It is good to shine here and heat it up, and it is good to use a little bit of residual heat.

The target of this time is a nearby star jm7812317, about 4.7 light years away from here, the stars near the cosmic string.

11 years ago, humans actually observed the flash of the nuclear bomb on the next planet through the hugest astronomical telescope!

Of course, the flashes of these nuclear bombs are very weak. According to the rational judgment afterwards, it should be a war within the planet, rather than a large-scale interstellar war.

In other words, this unknown civilization actually had an internal nuclear war!

Therefore, after some discussion, the top civilized leaders decided that there was no good goal in the first stop of the interstellar voyage, so they simply went to this planet for scientific investigation.

Even if you collect history and improve the history of new civilizations, it is good.

"However, the military aspect still needs to be strengthened... Since this civilization has broken out with an internal nuclear war, it is theoretically a militant type, and it is unlikely to rise again within decades, and it may not even be self-destructed. However, we must always guard against it..."

A sound suddenly sounded in my ears. It was my good friend Lu Zhongping. The two old men often looked at the space above here.

Xu Peng nodded: "Interstellar travel is definitely risky, but the benefits will be greater... It is too slow for us humans to explore technology here alone. If this continues, it will not be a good thing."

"Even if this civilization and overall technology are not as developed as ours, there will always be some different things..."

"Hey, if we come into contact with a stronger civilization, we will undoubtedly gain more... But we lack common sense about cosmic civilization, so it is better to get in touch with a weaker civilization."

"If we get good results, can we send a copy to the other two civilizations... I just don't know if the Earth Age exists, or we are just doing useless work."

The wrinkles on Lu Zhongping's face were like deep hills and valleys. He still remembered the bets he made with those young people. Some people said one hundred years, some people said two hundred years, and some people said three hundred years.

Almost sixty years have passed like this...

Time passes by like a flash of horses, and the world is like a white cloud and a deserted dog. I really hope that I can wait for news in my lifetime...

"I just don't know how many years I have to live."

Didi! Didi! Didi!

Just as they were so moved, the communication device on the power arsenal of the two suddenly rang. Xu Peng glanced at the red mark and felt a little nervous in his heart.

Red Emergency Meeting!

The levels of emergency meetings are divided into three types, the highest red, the second orange, and the lowest blue.

The red emergency meeting is almost the most important one. According to regulations, everyone who receives the message must rush to the nearby meeting site within 10 minutes!

"I don't know what happened..."

"Just the asteroid is about to hit the base? That's enough to meet the red standard, right?"

The two of them were full of worry and rushed back to the underground base, guessing randomly in their hearts.

I saw many people screaming and celebrating along the way, just like having a carnival party, and I was a little confused.

"What's going on?"

Xu Peng stopped a young man with an excited face, and the guy was even excited to protrude the blood vessels on his forehead one by one.

"Old Captain... Earth... Earth!" The young man started stuttering because he was too nervous and could only spit out the word " Earth". He couldn't continue to say it later.

However, what he wanted to express was not the same as he meant at all!

This made him more and more anxious. His face was as red as a red balloon, and he actually forgot what to say the second half.

"Is it because of the letter from the Earth civilization?" Lu Zhongping, who was standing aside, looked like he suddenly realized, "So that's it, this is really good news."

"But will the earth civilization really do this? Let's go and take a look at it."

This misunderstanding makes young people even more anxious. What is Earth civilization? It is obviously a human branch of Earth Age. These are two completely different concepts.

Finally, he struggled hard and thought of a good idea. He grabbed his hair hard. The severe pain of the grab made him break through the boundaries of his brain. "Old Captain, Professor Lu..."

"It's not Earth... it's Earth Age that sent us a reply!"
