On this day, after completing a series of memory experiments, Zhang Yuan unconsciously and easily hummed a minor.

The memory experiment of hemispheric civilization has always been the focus of research in recent years. With so many experimental objects of self sacrifice, some disciplines limited to ethical stagnation can flourish again.

His mood is very good, not because the experiment has made a great breakthrough, but... The destination of this voyage is coming. People will soon be able to see their old friends - TOS civilization, those large giant salamanders.

"I'm off duty. I'm off duty at last. Lao Zhang, do you have a meeting? Ha ha! "

"Oh, yes."

We can see that we are about to reach this familiar starry sky, and everyone is in a good mood. The gravitational wave detector has been able to detect the black hole born due to the neutron star collision.

Out of the illusory laboratory, you can see a bright starry sky when you look up.

This means that the curvature of the Alliance fleet slows down and enters the sub light speed state. Only at the slower sub light speed can we see the distant stars.

At present, the population of new human civilization has reached 920 million, almost in a stable and very slow growth state. The population of hemispheric civilization has expanded to 290 million due to the good development of genetic memory in recent years.

The two sides add up to 1.21 billion people, which can be regarded as a very strong alliance.

A sufficient population means that it can support the development of all walks of life.

On the other hand, when mankind left here, the military strength and scientific and technological strength were similar to or even slightly worse than the TOS civilization.

Because at that time, the new human civilization was too young, which meant that there were insufficient details. There were some defects in military strength, scientific and technological strength and population scale.

But now? The whole alliance has three war stars and tens of thousands of military spacecraft, large and small! The new human civilization is also the leader of the whole civilization, and its interior is showing a thriving development trend.

This change is so big that it will take only 400 years.

This is the benefit of external contact and collision!

If we encounter some opportunities, the speed of development is not comparable to that of a single civilization.

Therefore, due to the great leap forward in comprehensive strength, the new human civilization is also willing to accept its old friends and become a member of the alliance. At present, in this state, the other party is not likely to dominate, because the TOS civilization doesn't even have a war star!

……

At six o'clock in the evening, some astronomical observers are overlooking the starry sky in the Antarctic star astronomical observation room on Shanhai. A faint trace has appeared on the target colonial planet. Although it is only one pixel in size, it can be observed at least.

"Observers, please note that the third astronomical search is launched... The task is to search for the electromagnetic noise emitted by the TOS civilization."

"During the data sorting... No patrol spacecraft outside the TOS civilization has been observed for the time being..."

"Fourth search, start..."

Taking advantage of the automatic search time of the telescope, many young astronomers were laughing and even began to boast. They were satisfied with the current achievements of the new human civilization.

"I was thinking that if the other side found such a huge fleet, those giant salamanders might be shocked! Ha ha! "

"Of course! They can't have war stars. I bet they can't! "

The number of photons in this space is too small, and it is normal not to observe the other party's patrol spacecraft, because the patrol spacecraft of the TOS civilization may be deliberately invisible.

If the distance is longer, even the super telescope such as Antarctica or Polaris may not be able to capture small spacecraft.

But as time went by, people did not receive any communication information from the TOS civilization.

"It doesn't seem normal." One of the scientists said, "it's been several hours. Should the other party find us? You should signal us. "

The three war stars did not deliberately hide their movements. The light of nuclear fusion was on, so they flew slowly around each other's planetary system. Even if there was an information delay, they should also be observed by the other party.

One of the scientists frowned and said, "don't worry. At present, the distance between the two sides is still far away. Our war star will not drive into the inner ring of the planetary system... The optical signal is delayed in the universe. Maybe the other party is still meeting to discuss what to do! "

An older scientist nearby was checking the screen image. He said without looking back: "I was thinking that the other party would not have left... So there was no patrol fleet. It has been 400 years since we left here. In addition, the ships of the amoeba faction have broadcast the affairs of the universe administrator to the whole galaxy. The other party may indeed leave here. "

"It's not impossible... Did you come in vain? What a pity, I can't see those giant salamanders. "

"When I left here, I just graduated from high school and said goodbye to them. A twinkle of an eye, old. "

"Not necessarily. Maybe the other party saw that our fleet was too strong and hid directly, thinking that we were just passing by. They don't know it's the fleet of our new human civilization, do they? "

All the staff laughed. Yes, in less than a generation, earth shaking changes have taken place in the new human civilization.

At the time of departure, there was only one Titan class, plus five aircraft carrier classes. At that time, new humans thought their military strength was fairly good.

But now?

There are two war stars controlled by people!

And a loyal ally!

The loyalty of hemispheric civilization is indeed amazing, because the illusory laboratory completely holds each other's handle: cloning ancestors. And it is really promoting the solution of the problem, not fooling around.

If the enemy really appears and wants to destroy the new human civilization, that group of crazy hemisphere people will be the first to rush up. No matter how, they must protect the scientists in the illusory laboratory, otherwise their dreams will be completely ruined!

Because the interests of both sides are highly bound, hemispheric civilization has almost become a loyal horse of new mankind.

One of the old people sighed: "inside information, inside information, most of our three war stars are actually the inside information of hemispheric civilization. I have to admit that they are indeed a civilization with great potential and boldness. "

"The inside information needs the accumulation of a hundred or a thousand generations. Many civilizations simply do not have the patience to develop war stars... Including our human civilization."

The old scientist suddenly smiled: "we may not have such good luck in the future, but we have to accumulate it slowly by ourselves. Now it is also in the process of accumulation. "

One of them asked, "by the way, do you think the TOS civilization will smoothly join us?"

"I don't know. That's what we need to worry about, but I don't think it's that simple... In an alliance, bilateral relations are easier to control, and the tripartite confrontation seems a little troublesome. Everyone knows that. "

"... wait a minute, what's that?" While everyone was discussing, one of the scientists suddenly screamed loudly.

Everyone turned their heads together. The Antarctic star telescope seemed to have found something. A picture appears on the screen with a small black dot on the edge.

After enlarging the picture, you will find that the black spot is a regular geometry!

Everyone suddenly calmed down, and one of the leading men said, "enlarge the resolution of the picture a little more!"

Everyone's pupils contracted violently when they saw the real appearance of the black spot.

A... Spaceship!

Broken ship!
