Seven years ago.

Glitzer 581, an ordinary and impermanent star and a rock planet, has a race named human on it. It is developing a huge spaceship named "Kunlun Mountain" in full swing to make final preparations for its long-distance voyage plan.

Everyone is striving for their own goal

On this day, Professor Li Zhi, who is in charge of astronomical observation, suddenly detected an unusual fluctuation.

It was a regular radio wave, very weak, but continuous.

He frowned and examined, wondering if the wave was a fragment of a neutron star pulse. In fact, most of the signals detected by the Observatory are from these neutron stars or very distant supernovae, and these signals have little meaning..

After a while, this series of pulse bands appeared again, and it was the same rule!

Staring at the screen for a long time, suddenly, Professor Li realized something and yelled at his assistant: "record quickly, record everything!"

"Search the source of the signal!"

In order to cultivate the public's interest in foreign exploration, astronomy, including cosmology, has been a key project supported by the new civilization. Many students practice here.

And searching for alien signals, including the signals of earth civilization, is the top priority.

Although There hasn't been much progress. It is estimated that the real alien civilization has not used electromagnetic wave for communication for a long time.

The young students pondered over the radio waves. Because it is very weak, there are many missing signals, but there are some rules.

"It's so regular!"

"It's a string of signals, really from civilization!"

"Don't get excited. Try to decipher it."

Professor Li had a hunch that it was absolutely amazing.

Then, he heard the observation room next door also began to revel, it is obvious that both sides have a common discovery.

"Again! There's another string of signals! " A boy exclaimed.

Radio telescope detected a lot of information coding!

More and more, more and more, for hours!

This time, it's not just a few words, but a whole

103 trillion!

103 trillion!

A few hours later, the supercomputer was analyzing and deciphering the data just detected. Professor Li knocked excitedly on the door of the next room, pretending to be calm, and said, "Lao Guo, it seems to be something amazing."

"Well, have you found out? Is it a signal from the earth civilization? Or alien civilization? I'm more interested in the signals of alien civilization. "

Lao Guo also blushed and said enthusiastically, "no, it's definitely not the earth civilization, because it's not in the same direction at all. One thousand percent is not On the contrary, I suspect that it is the human beings on the golden sun who send us the signal. "

"The golden sun?" Professor Li was stunned and then patted his head. He almost forgot about it.

"Yes! This string of signals is likely to come from kapotan

The report was soon passed back to the captain's room. Because the use of a traditional remote error correction code, it is easy to decipher out.

When he heard about it, even Zhang Yuan was surprised and soon became excited.

"Has the human race of the golden sun arrived smoothly No, in theory, they should have arrived faster than us. "

"Call an emergency meeting!"

At the same time, he gave several orders.

"Maximize the astronomical observation equipment, and don't miss any information."

"Call the reporters, too."

……

More than ten minutes later, the conference room was already full of people. Everyone was talking excitedly, and there was a kind of fanatical atmosphere in the air.

Li Zhendong, in particular, is so excited that he is in a mess. There are also a group of physicists who are crazy about strange words like "graviton" and "cosmic string".

All in all, this news can be said to be the best news about human beings in the past century!

In other words, the branch of the golden sun does not belong to the earth civilization itself, but another brand-new civilization.

But when you think of the boundless universe, the distant planet kapotan, and another active and energetic branch of human beings, is there anything more to look forward to and celebrate in the world?

Zhang Yuan played the translated letter directly on the screen.

“…… Dear Earth age, Hello, this is golden sun. Repeat for the seventh time

“…… Dear Earth age, Hello, this is golden sun. Repeat for the eighth time……

“…… Dear Earth age, Hello, this is golden sun, repeat 106 times

This sentence has been repeated 107 times, so that all of you here are a little impatient. After Professor Li of astronomy explained it, everyone was quiet again.

The reason is that the ultra long distance electromagnetic wave communication costs a huge amount of money, and it is impossible to inform the other party in advance that we are going to send information, so we must give the other party a preparation time. Only this kind of repeated information can arouse the attention of the other party.

Otherwise, this piece of information may be directly ignored in the past and will never be received again.

"I see." Ye Kaifu, sitting at the bottom, nodded.

After 107 repetitions, we finally got to the point.

"Hello, colleagues of the earth age, this is Kaptan, the branch represented by the golden sun spacecraft. I'm Xu Peng, the then captain."

"Our civilization has been developing here for 544 years. It is necessary and obligatory to report the 500 years of history to you of the earth age, so as to better plan your future."

The tone was so heavy that everyone could not help holding their breath.

The two civilizations adopted almost the same strategy, that is, taking "new civilization historiography" as the guiding ideology, but there will be some differences in minor policies.

Because the history of the two civilizations is different. The earth age encountered many stories, and the golden sun must have encountered different stories.

Due to the different development history, the ideology of the people and the culture of the whole society will be very different.

This is the complexity of a civilization. Even if both sides are human beings and of the same origin, there will still be great differences.

But in the process of development, the golden sun appeared a series of small problems.
