The mass of this satellite is about 7.5 tons, which is not much different from Xiao Yu's estimate.

Xiao Yu first analyzed its material system.

The results show that the materials it is made of are all elements common in the universe, and there are no materials that Xiao Yu cannot understand. Moreover, its material performance is not stronger than that of Xiao Yu's here, after being strengthened by Wood Spirit and Black Worm.

In Xiao Yu's speculation, an alien super civilization that can build a fleet of such a huge mass cannot still use such "low-level" materials. In Xiao Yu's heart, he became more and more puzzled.

The next thing to analyze is its powertrain. From the power system, we can see the degree of scientific and technological development of a civilization.

After taking it apart, Xiao Yu looked at the familiar nuclear fusion engine and was a little speechless in his heart.

"I didn't expect you to really use nuclear fusion energy? And, is it also the electrical energy used? Kindness? Photonic Computing Control Board? God, don't you want to be so similar. ”

Although there are some slight differences between the fusion engine in this satellite and Xiao Yu's, the overall principle is the same.

Looking at everything familiar in front of him, Xiao Yu felt like he couldn't cry or laugh, but at the same time, his heart was greatly relaxed. Even if there are many contradictions that cannot be explained, but in the end, it uses nuclear fusion power, relies on electricity to transmit energy, and relies on photonic computing control boards to construct computing modules, which means that the scientific and technological level of this civilization will definitely not exceed Xiao Yu too much.

At the same time, Xiao Yu once again affirmed his speculation about the similarity of civilization progress. Quite simply, since most of the civilizations have developed from low to high, it is very likely that they will also go through a similar process as the civilization of the earth. Although there will be differences in the details because of the differences in civilizations, the general direction is the same, such as chemical energy, such as nuclear energy.

"Huh? What is this? Xiao Yu bypassed the power module and began to check the rest of the parts, and at this time, a strange thing caught his attention.

It was something that resembled a camera on Earth, with a protruding lens with a smooth glass lens in it.

Xiao Yu disassembled it and began to analyze the various subtle photon circuits inside.

Gradually, Xiao Yu was attracted by this photon circuit. Xiao Yu stopped all the other irrelevant calculations and mobilized at least twenty percent of his computing power to analyze the circuit board.

After analyzing for fifty minutes, Xiao Yu exhaled and came back to his senses.

"From this circuit board, you can see that they are at least beyond my five-year technological level. Otherwise, they would not have been able to design such an efficient line. ”

This five-year period is calculated based on the level of scientific and technological progress on the earth, and now Xiao Yu, because of the lack of sufficient materials to carry out the research of basic physical theories and the rest of the various experiments, science and technology have long fallen into stagnation.

Xiao Yu learned a lot from this circuit board, and at the same time, he also analyzed the role of this instrument.

This is a thermal imaging detector, which works on the principle of something similar to a night vision device above the Earth.

After analyzing this instrument, Xiao Yu began to analyze the next instrument. It took twenty hours of analysis for Xiao Yu to finish analyzing the entire instrument.

This is indeed a satellite, and its main role is to find a heat source on top of a massive object. This function made Xiao Yu unable to figure it out. Heat? Need to look for it?

At the same time, Xiao Yu also has a general understanding of the technology of this civilization. Generally speaking, this is a civilization that has surpassed Xiao Yu's current science and technology for about ten years, that is, the utilization efficiency of nuclear fusion is higher than Xiao Yu, the computing power is faster than Xiao Yu, the spaceship built is faster than Xiao Yu, and the weapon is more powerful...... That's it.

In short, the gap is not very large.

Xiao Yu already has a comprehensive understanding of the science and technology of this civilization, and at the same time, his heart has also settled down.

Xiao Yu thought, "It's a little strange, this satellite is obviously built for a large object that is at least twice the size of the earth, and they only have technology that surpasses me for ten years, so it is impossible to build such a large fleet." ”

"Let this question go for the time being, at present, what needs to be determined is, what kind of attitude should I have towards this civilization?" Xiao Yu thought about it and slowly analyzed.

"According to the model, if two civilizations with a similar level of technological development meet in the universe, the greatest possibility is ...... After initial temptations and even conflicts, peaceful contacts are initiated, information is exchanged, or material trade is conducted, and then they are separated peacefully. This is the first time I've encountered an alien civilization, and perhaps I should show some kindness to them. ”

But I can't speculate about their social structure or moral system, that is, I can't know whether they mean good to me or malicious to me. Or...... Should I show kindness and show my force? ”

Xiao Yu remembered a theory that was once very popular on the earth, the Dark Jungle Theory. In this theoretical system, there is no possibility of peaceful coexistence between two different interstellar civilizations. Xiao Yu felt that at this moment, he seemed to have fallen into the so-called "chain of suspicion".

Xiao Yu didn't know if the Dark Jungle Theory was correct, and Xiao Yu didn't risk his life to test his interest in the Dark Jungle Theory. Xiao Yu only knew that his contact with the other party was inevitable.

Then, Xiao Yu must come up with a contact plan as soon as possible.

"Putting aside whether the Dark Jungle theory is correct or not, anyway, from my standpoint, if the benefits that can be obtained are less than the price that will be paid, then I will not choose to pay. The same is true in the universe, if there is a greater benefit to coexist peacefully with a civilization, I naturally will not choose to attack it. I believe that this unknown civilization will also have such logic. All I need to do, then, is very simple, show my system of force and deter them while demonstrating the benefits of peaceful coexistence with me. ”

Two civilizations with a similar level of technology. If conflict breaks out, it can end up together, and if it coexists peacefully, it can be beneficial for both sides. Which one to choose, as long as it is a civilization with normal wisdom, must be clear in their hearts.

"In the final analysis, interests, everything is interests, and interests are the supreme guiding principle." Xiao Yu thought silently, "So, how to show the benefits and deterrence at the same time?" ”

"Put this issue aside for now, and the first priority is to find out about them. They're not very far away from me. A presence hidden in the shadows, not knowing whether it is benevolent or malicious, is very dangerous, although I don't know if they have discovered me. But if I find them first, I'll have the initiative to make contact. ”

Xiao Yu slowly adjusted the formation of the fleet, adjusting the entire fleet into a huge circle with a diameter of 8,000 kilometers. In this way, Xiao Yu is equivalent to using these more than 800 spaceships to form a huge radio telescope array. At the same time, Xiao Yu installed a condenser on each spacecraft, so that Xiao Yu could collect signals in various bands, whether it was infrared, ultraviolet, visible, X-ray, gamma rays, etc., all of which could not escape Xiao Yu's detection. Even if it weren't for the limitations of science and technology, Xiao Yu would still want to get a neutrino and gravity wave detector out.

Xiao Yu searched for a month, but he didn't find any substances that seemed to be the creation of civilization.

"It shouldn't be." Xiao Yu pondered, "All kinds of signs indicate that this alien civilization must be near me. Don't...... They found me too? So radio silence was chosen? ”

Xiao Yu began to think about a question. That is, in the dark universe, in the absence of visible light, how to discover an object that does not emit any radiation of its own, or only emits a trace of radiation, similar to nothing?

In turn, Xiao Yu also began to think, how could this civilization, which has surpassed himself for nearly ten years, find himself when he kept the radio silent, turned off all nuclear fusion engines, and shielded all the radiation in the visible and invisible light bands?

Xiao Yu calculated, but couldn't find any technology that could detect himself in this situation.

But there is one thing, Xiao Yu can be sure that if he didn't deliberately hide, then there are still many ways to find himself.

That...... Does it also mean that the other party is also deliberately hiding?

Xiao Yu was shocked.

It seems that there is only one explanation, otherwise, why can't you find each other?

"Take the initiative to show your figure, show your kindness and your own force to the other party, and take the initiative to contact the other party?" Xiao Yu thought nervously, but it was very risky to do so, and after showing his form, what greeted Xiao Yu might be a large-yield hydrogen bomb. Xiao Yu thought about it for a long time, but he couldn't make up his mind to take this risk.

The current situation is very delicate. Two civilizations with a similar level of technological development are deliberately hiding themselves. And Xiao Yu can be sure that the other party is also desperately looking for himself. In this case, no one dares to take risks.

So, how can the impasse be broken?

The contact between the two civilizations is inevitable. Because the two sides are already not far apart. And taking the initiative to leave means that you want to start the nuclear fusion engine, which means that your body will be exposed.

At the same time, Xiao Yu thought of a question.

Yourself, has it been exposed?

After all, he had operated the spaceship before, captured the satellite, and manipulated the spacecraft to form an array of radio telescopes. In this process, Xiao Yu had already used the lowest power, but Xiao Yu could not confirm whether the other party had more advanced technology to discover the trace amount of radiation he emitted.

"It's certain that the other party already knows about my existence, otherwise they wouldn't have been able to hide it deliberately. I just don't know, my specific coordinates are exposed. ”

Xiao Yu was thinking about this question, and suddenly, Xiao Yu detected a faint signal.

This signal is very weak, if it weren't for Xiao Yu arranging a radio telescope array, Xiao Yu wouldn't have been able to detect this signal at all.

Xiao Yu's heart tightened, and he immediately began to analyze this signal.

As a result, Xiao Yu was shocked.

"Hey, this is the signal for the trigger-type hydrogen bomb detonator!"
