Super Battleship Reborn

This radio wave has obvious traces of intelligent civilization. Specifically, it has three triple-repetition bands and five double-repetition bands, and there seems to be some logical connection between the repeating bands.

Although there is no way to locate the source of this radio wave, with the current information, Xiao Yu can be sure that it is not far from him.

Xiao Yu's mood became tense. This is probably the first time humans have come into contact with an alien intelligent civilization. And receiving radio waves in such a void can prove that this alien civilization has at least acquired interstellar voyage capabilities.

It wouldn't be so unlucky, would it? Xiao Yu muttered silently.

Xiao Yu doesn't think that the rest of the alien civilizations will be like himself, when the level of technology only reaches the ability of interplanetary navigation, they will start interstellar voyages. In other words, this civilization is likely to have reached a speed of five percent of the speed of light. This represents an insurmountable technological gap. In front of this technology, Xiao Yu will be a lamb to be slaughtered without the ability to resist.

Xiao Yu put the remaining 800 or so spaceships into radio silent mode, turned off all visible light emission, and at the same time, turned on all kinds of observation equipment to their maximum power.

In the boundless dark universe, Xiao Yu sneaked silently.

Xiao Yu started the intense decoding work, trying to translate the signal carried in this radio wave into a language he could understand. At the same time, Xiao Yu secretly prepared all the laser cannons, high-speed cannons, hydrogen bombs, etc. for launching, ready to fight at any time.

Under such circumstances, Xiao Yu could not escape. Because now, that civilization should not have discovered Xiao Yu, and if he escaped, it would mean starting the nuclear fusion engine, and as soon as the nuclear fusion engine started, it would emit strong radiation, and it was almost certain that he would be discovered by the other party, and then You will become a target yourself.

Xiao Yu could only maintain the current speed, and under the action of inertia, he slowly moved forward and slid forward.

A full ten days have passed. During this time, everything was quiet as usual. Xiao Yu just waited in silence and prepared in silence.

Then, Xiao Yu received the second message. This information still shows obvious logical characteristics. These two information receptions finally allowed Xiao Yu to roughly locate the source of the information.

Probably... the source of this information, 800,000 kilometers ahead of Xiao Yu, is approaching Xiao Yu at a speed of four kilometers per second.

Xiao Yu is approaching Tianyuan 4 at a speed of 550 kilometers per second, which means that this unknown information transmitter is also approaching Tianyuan 4, but its speed is only 546 kilometers per second. According to this speed, Xiao Yu will contact him in two and a half days.

Escape, or? Xiao Yu was caught in a contradiction.

Let's analyze the information first. Xiao Yu calculated, With two pieces of information as a comparison, it will take about three hours to decipher its meaning. After analyzing the information, decide whether to escape.

Xiao Yu manipulated huge computing power and performed a lot of calculations on these two pieces of information. After three hours, Xiao Yu finally cracked the two pieces of information.

The No. 7 Sky Survey Satellite is about to run out of fuel. The speed is 13.5 kilometers per second. The detection module has been turned off. Please ask for the next step.

The No. 7 sky survey satellite has successfully deorbited, and the communication module is about to be turned off. Please confirm.

Looking at these two pieces of information, Xiao Yu fell into contemplation.

From the analysis of the literal meaning, this is a device called Sky Survey Satellite No. 7, a message communicated with a console somewhere. Of course, the original text of the message did not say Seventh Sky Survey Satellite. The general meaning of the original text seemed to be some kind of instrument numbered seven that could fly in orbit. It was translated by Xiao Yu as Seventh Sky Survey Satellite.

There was ten days between the two messages. According to its logic, it seems that after the first message was sent, the console went through some kind of control, and it took ten days to maneuver the satellite out of its original orbit and turn off its communication module.

There is a lot of information in this.

And what Xiao Yu needs to do is to analyze the information he needs from these two short messages, such as the other party's technological level, such as the other party's social model, and most importantly, whether the other party is a good-willed civilization or a Malicious civilization, analyze it.

The task is daunting, the amount of intelligence is too small, and there are too many things to analyze. But if it can't be done, Xiao Yu sighed and started the modeling work.

One social model after another was formed, and then the models that did not conform to the known intelligence were overturned, and the models that conformed to the known intelligence were continuously improved. Finally, Xiao Yu analyzed several points of information.

First of all, it is known that this satellite-like instrument was discarded after the fuel was consumed. Then it can be known that in the eyes of this civilization, the cost of recycling this instrument is higher than the instrument itself. This made Xiao Yu puzzled.

Since interstellar voyages are launched, it is inevitable to reserve a large amount of fuel. And a normal operating instrument has too many components that can be recycled. For example, Xiao Yu, after the village-level spacecraft is damaged, Xiao Yu will spend fuel to capture it and disintegrate it, and recycle the available parts on it. , rather than discarding it directly.

It seems that this civilization's fleet has fallen into an energy crisis, and this is the only explanation. Xiao Yu thought silently, and his heart became heavy.

Since this civilization is in an energy crisis, Xiao Yu is in danger. Because this civilization is likely to rob Xiao Yu.

There was another message, The speed is 13.5 kilometers per second, Xiao Yu was also confused.

13.5 kilometers per second? Xiao Yu pondered, Since the speed is marked, there must be a reference. Then, what is this instrument moving relative to? At present, this instrument is only possible It is relative to the movement of the console, so it is a little difficult to understand. Normally, it takes at least a year for an instrument to run out of fuel. In such a long time, it can fly a distance of 400 million kilometers. However, judging by the strength of the signal I received, this signal cannot be picked up by a console 400 million kilometers away.

This is a contradiction. Xiao Yu thought carefully and had an explanation in his heart.

To explain this contradiction, it can only be explained by the fact that the instrument is in a circular motion around the console. Xiao Yu manipulated the huge computing power and made many calculations in an instant. But in this case, new contradictions will emerge. Under what circumstances does a fleet need a satellite with a sailing speed of 13.5 kilometers and rotates around it at all times?

Xiao Yu has calculated that only a star with a mass that is 1.6 times that of the Earth will orbit at a speed of 13.5 kilometers.

This is an astonishing conclusion.

Could it be that the total mass of this fleet is 1.6 times that of the Earth? That's why a special instrument is needed to monitor the fleet's situation at any time? No, it's impossible. The fleets have their own communication systems, so why do they have to get a satellite? Come out? Moreover, how could such a huge fleet not recover the fuel of a satellite?

Xiao Yu was puzzled, and could not unify these two contradictory pieces of information in any case.

Among these two pieces of information, a very key word is also involved, detection module.

Obviously, the detection module is only needed when there is an unknown situation. Then, under what circumstances does a fleet need to use an external instrument to detect the internal structure?

This is another contradiction.

I can't figure it out, let's give up here first, and calculate their civilization level first. Xiao Yu calculated in his heart.

First of all, it was established that they did not master telematics, that is, in terms of quantum theory, they were no deeper than me. Then, in terms of energy, the first message said that the fuel was about to run out, and then it ran for another ten days. It takes time to turn off the communication module, so I can make some speculations about the fuel utilization rate...

Assume for the moment that the instrument is in circular motion and mainly relies on inertia to maintain its orbit, and from the point of view of its abandonment, its mass cannot be too large, otherwise it cannot be abandoned so easily, and assume its mass is ten tons for the time being , and assuming that only 0.1% of its fuel remains, then, from a comprehensive analysis...

They're still fusion energy.

Xiao Yu came to this conclusion.

But a new contradiction has emerged. How can a civilization that uses nuclear fusion as energy build such a huge fleet?

One question after another came out of Xiao Yu's heart.

Since this satellite has been abandoned, perhaps, I can capture it. Xiao Yu suddenly had an adventurous idea in his heart.

After thinking for a while, Xiao Yu gritted his teeth and made up his mind.

Go! What's not to dare! Anyway, I can't run now. It's better to find out their civilization level as much as possible. Even if they die, they will die vigorously!

After making up his mind, Xiao Yu turned the optical detection equipment to the highest precision. Finally, with the help of weak starlight reflection, Xiao Yu found the instrument at an estimated location offset of 500 kilometers.

It was a strange instrument with about ten cubic meters in shape, shaped like a starfish.

Looking at this thing in front of him, Xiao Yu was very excited. This is Xiao Yu's first contact with an alien civilization!

Xiao Yu manipulated a village-level spacecraft and approached the satellite with the lowest power. Under the lowest power, the nuclear fusion engine of the village-class spacecraft only emits extremely weak radiation, and it must not be discovered by the inferred alien civilization. After getting close, Xiao Yu used a robotic arm to grab the satellite into the cabin.

Then it was transported into the largest and most well-equipped county-level spacecraft for analysis.
