Chapter 34: Two messages

This burst of radio waves has obvious traces of wisdom and civilization. Specifically, it has three repetitive bands, five repetitive bands, and there seems to be some logical connection between the repetitive bands.
Although there is no way to locate the source of this radio wave, with current information, Xiao Yu can be sure that it is not far from himself.
Xiao Yu's mood grew tense. This is likely to be the first time that human beings have contacted an alien intelligent civilization. When radio waves are received in such a void, it can be proved that this alien civilization has at least acquired interstellar voyage capabilities.
"Isn't there such a bad luck?" Xiao Yu muttered silently.
Xiao Yu doesn't think that the rest of the alien civilizations will also be like themselves. When the level of science and technology only reaches the ability of interplanetary navigation, they start interstellar navigation. In other words, this civilization is likely to reach a speed of five percent light speed. This represents an insurmountable technological gap. In front of this technology, Xiao Yu will be a lamb to be slaughtered without resistance.
Xiao Yu turned the remaining 800 spacecraft into radio quiet mode, turned off all visible light emission, and turned on various observation equipment to the maximum power.
In the endless 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 laser cannons, high-fire rate machine guns, hydrogen bombs, etc. to launch and was ready to fight at any time.
Under such circumstances, Xiao Yu could not escape. Because Xiao Yu has not yet been discovered by that civilization, and running away means starting a nuclear fusion engine. Once the nuclear fusion engine starts, it will emit strong radiation, and it is almost certain that it will be found by the other party. You will become a target.
Xiao Yu can only maintain the current speed, under the effect of inertia, slowly go forward to taxi.
Ten days have elapsed. During this time, everything is as quiet as usual, Xiao Yu just waits in silence and prepares in silence.
Xiao Yu then received the second message. This message still shows obvious logical characteristics. These two times of information reception finally made Xiao Yu roughly locate the source of the information.
Probably ... this information emission source is approaching Xiao Yu at a speed of four kilometers per second in front of Xiao Yu's 800,000 kilometers.
Xiao Yu is approaching Tianyuan 4 at a speed of 550 kilometers per second, which means that this unknown information emission source is also approaching Tianyuan 4, but its speed is only 546 kilometers per second. At this rate, Xiao Yu will contact him in two and a half days.
"Escape, or?" Xiao Yu fell into contradiction.
"Analyze the information first." Xiao Yu calculated, "With two pieces of information as a comparison, it will take about three hours to crack the meaning. Wait for the information to be parsed before deciding 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 fuel of the No. 7 survey satellite is about to run out at a speed of 13.5 kilometers per second. The detection module has been shut down and requested next instructions."
"The 7th survey satellite successfully got out of orbit, and the communication module will be shut down soon. Please confirm."
Looking at these two messages, Xiao Yu was lost in thought.
From the literal analysis point of view, this is a message called "Seventh Sky Survey Satellite", which communicates with the console somewhere. Of course, the original text of the message does not say "Seventh Survey Satellite". The general meaning of the original text seems to be that it is a kind of instrument numbered 7 that can fly in orbit. Translated according to the text of the earth, it was translated by Xiao Yu into "Seventh Sky Survey Satellite".
There was a ten-day interval 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 spent ten days manipulating the satellite out of its original orbit and shutting down its communication module.
This contains a lot of information.
What Xiao Yu needs to do is to analyze the information he needs from these two short messages, such as the technological level of the other party, such as the social model of the other party. Malicious civilization, analyze it.
This task is arduous, the amount of information is too small, and too many things need to be analyzed. But if it doesn't work, Xiao Yu sighed and started modeling.
Social models were constructed one after another, and then models that did not conform to known intelligence were overthrown, and models that conformed to known intelligence were continuously improved. Finally, Xiao Yu analyzed several points.
First of all, it is known that this satellite-like instrument was abandoned after fuel consumption was completed. Then it can be seen that in the eyes of this civilization, the cost of recycling this instrument is higher than that of the instrument itself. This confused Xiao Yu.
Now that the interstellar voyage has begun, it is inevitable that a large amount of fuel will be stored. There are too many components that can be recycled on a normally operating instrument. For example, Xiao Yu, after the village-level spacecraft is damaged, Xiao Yu will use fuel to capture it and disassemble it, recycling the available parts above. Without throwing it away.
"It seems that this civilized fleet has fallen into an energy crisis, and this is the only explanation." Xiao Yu thought silently, feeling heavy.
Since this civilization has fallen into an energy crisis, Xiao Yu is in danger. Because this civilization is likely to rob Xiao Yu.
There is another message, "The speed is 13.5 kilometers per second", Xiao Yu is also very confused.
"13.5 kilometers per second?" Xiao Yu thought, "Since the speed is marked, there must be a reference object, then, what is the relative movement of this instrument? At present, this instrument is only possible It ’s relative to the console, so it ’s a bit difficult to understand. Normally, it takes at least one 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 could not be received by a console 400 million kilometers away. "
This is a contradiction. Xiao Yu was thinking carefully and had an explanation in his heart.
"To explain this contradiction, we can only explain that this instrument is making 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 arise again. Under what circumstances will a fleet need a satellite with a speed of 13.5 kilometers and always orbit it?"
Xiao Yu has calculated that only a star with a mass of 1.6 times that of the earth will reach a speed of 13.5 kilometers.
This is an amazing conclusion.
"Does this fleet have a total mass of 1.6 times that of the earth? So it is necessary to have a special instrument to monitor the fleet at any time? No, it is impossible. The fleet has its own communication system. Come out? And how could such a huge fleet not recover the fuel of a satellite? "
Xiao Yu was puzzled and could not unite these two contradictory pieces of information.
In these two pieces of information, there is also a very important word, "detection module".
Obviously, the detection module is needed only 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 degree of civilization first." Xiao Yu thought in his mind.
"First of all, they can be sure that they did not master hyper-range communication, that is, they are not deeper than me in terms of quantum theory. Then, in terms of energy, the first message says that the fuel is about to run out, and then it runs for another ten days Time to shut down the communication module, then I can make some speculations about fuel utilization ... "
"For the time being, suppose the instrument is doing circular motion and mainly rely on inertia to maintain its orbit. From the perspective of its abandonment, its mass cannot be too large, otherwise it cannot be abandoned so easily. For the time being, its mass is ten tons. , Assuming that only 0.1% of its fuel remains, then a comprehensive analysis ...
"They remain nuclear fusion energy."
Xiao Yu reached this conclusion.
But new contradictions have emerged. How can a civilization that turns nuclear energy into an energy source build such a large fleet?
One question after another emerged from Xiao Yu's heart.
"Since this satellite has been abandoned, maybe I can capture it." Xiao Yu's mind suddenly came up with a risky idea.
After thinking about it, Xiao Yu gritted his teeth and made up his mind.
"Don't! What dare not! Now you can't run anyway, it's better to find out as much as possible about their civilization ~ EbookFREE.me ~ Even if they die, they will die vigorously!"
After making up his mind, Xiao Yu drove the optical detection equipment to the highest accuracy. Finally, with the weak starlight reflection, Xiao Yu found the instrument at an estimated location offset of 500 kilometers.
It was a weird instrument about a dozen cubic meters, shaped like a starfish.
Looking at this thing in front of Xiao Yu, Xiao Yu was excited. This is Xiao Yu's first contact with alien civilization!
Xiao Yu controlled a village-level spacecraft and approached the satellite with the lowest power. At the lowest power, the fusion engine of the village-level spacecraft only emits extremely weak radiation, and it is unlikely to be discovered by speculative alien civilizations. After approaching, Xiao Yu grabbed the satellite into the cabin with a robotic arm.
Then it was transported into the largest and most complete county-level spaceship for analysis.
