There is such a sentence in Rao Xin's novel - the sign of a person's maturity is when he begins to introspect.

The biggest reason for a person's self-reflection is that he is dissatisfied with the status quo or the future, and immature people are dissatisfied with it, and they will look around him, to the world, which includes all the environment, family, friends, work, and ...... And a mature person is always looking at himself.

Because mature people know that in this world, the only thing a person can change is himself, and if he wants to change the current situation or the future, he can only start by changing himself.

In the past, Wu Xiaoqing actually had this vague cognition when he began to try to study. It's just that his conditions at that time were not enough to support himself to complete such a difficult transformation.

What Wu Xiaoqing has done can only be regarded as a mature attempt - but without the search and rescue team, he may need to try for quite some time.

This sentence in Rao Xin's novel is to bring out the next proposition.

He said that the sign of the maturity of a civilization is often the time when a civilization begins to introspect.

In this sense, the current earth civilization is simply the same as Wu Xiaoqing more than a month ago. I also began to try to read more books and study more...... But in the end, when I did the question, it was still a mess.

To be honest, it was impossible for the previous Wu Xiaoqing to stand at the height of the entire civilization to see the planet he lived on and his way of life.

Don't say it's him, even if Wu Xiaoqing is sent to the United States to be president, he doesn't have any time to worry about civilization...... The earth has always been a pragmatic civilization, which is the same pragmatic as Wu Xiaoqing in the past - there is no money to spend to borrow, and if you can't borrow it, you can cheat, if you can't do it, you can sell it, and borrow usury after selling your belongings...... In the end, he couldn't pay back the money - Wu Xiaoqing is stronger than the presidents, anyway, I haven't heard of the presidents being forced by creditors to jump into the river - there are a few who were hanged.

In this regard, Wu Xiaoqing is still a bit of a single.

The earth civilization in reality is actually a more thorough scoundrel than Wu Xiaoqing.

Almost anyone with long eyes can see that such an earth civilization is actually inevitably in crisis - although, in the glasses, the earth civilization seems to be very safe.

If there's anything uncomfortable about being smart – it's that the stupidity of the world is gradually losing patience and even finding it unbearable, which is the biggest symptom.

On this point, Rao Xin obviously feels the same way as Wu Xiaoqing. That's why he writes so many novels - generally speaking, people who write novels are holding their words in their stomachs, and they are so uncomfortable that they simply vomit them all to make themselves happy. Of course, if you can still make a few bucks, it will be even more enjoyable.

Rao Xin obviously has his own clear imagination of the ideal civilization, or in other words, the concrete form of utopia.

Of course, these imaginations are completely groundless, because with the technological level of human eyes, they have not yet come into contact with any foreign civilization. Or rather, it has been contacted, but humans themselves are completely unaware of it - such as search and rescue teams.

But these imaginations are convincing.

This persuasiveness does not mean that some details of the imagination are supported by evidence, in a practical sense, Rao Xin's novel is completely full of loopholes.

After all, Rao Xin himself is just an ordinary college student, he can't go to the alien planet to investigate and write reports one by one, and there is no person like the collection team to take him to do the task, and his mastery of technical details is completely inferior to that of professional personnel.

This persuasiveness, more so than that, is a formal beauty, like mathematics, deduced from several axioms that are also imaginary...... In the end, a magnificent mathematical edifice was constructed.

Rao Xin's "utopian" edifice is not grand yet, and before he came into contact with Qinglan Consulting, perhaps he himself did not seriously think about how to rigorously express the alien civilization in his cognition and imagination - after all, if he just writes a novel, it is much more casual.

But after Qinglan Consulting gave him a lot of money and asked him to do this thing, Rao Xin began, and really took this matter seriously and did it as a scientific research project. To this end, he also consulted some university teachers and cautiously made some understanding of research-based topics.

Basically, in the materials in front of Wu Xiaoqing, all the problems were designed by Rao Xin.

Regardless of the rights and wrongs of this design, Wu Xiaoqing has only performed a few missions, and when it comes to the understanding of civilization, he does not necessarily understand a lot.

According to Wu Xiaoqing's glasses, seeing the number of civilizations, there is an obvious fact that is certain - there are a large number of civilizations in the entire universe! And many of these civilizations will have crises...... And this kind of crisis is very necessary to save the civilization to which the search and rescue team belongs.

And the search and rescue team asked themselves to talk to Rao Xin, so it is naturally very clear that Rao Xin's research has a very important reference significance, whether this meaning is positive or negative.

Now it seems that it is more of a positive - although the search and rescue team did not mention a word, but the search and rescue team supported Rao Xin to do this project, and left Rao Xin in the company, and specially translated the material text of Rao Xin for himself...... Obviously, in the eyes of the search and rescue team, these things have a special meaning.

And this meaning has a great relevance to their next mission—no, most likely, this one.

……

When he arrived at the space station, Wu Xiaoqing found that everyone else had already arrived.

Wang Youquan was on the edge of the teleportation point, and it seemed that he had just come over for a while, and was trying to operate the flying sword with his mobile phone. Wu Xiaoqing directly helped - after all, he had a lot of practice experience before.

On the way in, Wang Youquan, who usually talks little, began to speak: "The negotiation over there is over!" Get back six batteries at once! It's the kind of antimatter! ”

Wu Xiaoqing sighed, not particularly excited. In fact, when Yan Xiu and they set off, Wu Xiaoqing discussed it with the search and rescue team - the so-called nine major factions have completely lost the initiative, and with the former head of Samadhi, surrender is a matter of course. Of course, there is nothing wrong with not surrendering...... Yevgeny was here and ready to drop a second nuclear bomb at any moment.

The search and rescue team has prepared for the worst, that is, even if they can't get any antimatter batteries, relying on this battle, after defeating the nine major factions, they can also organize everyone in the Ascension Heaven Realm after the power tower is restored, and use them as a source of power - let them replenish their power into the antimatter battery.

Of course, this will definitely be a significant extension of the mission, perhaps three or five months longer...... But compared to the risks of the nine major factions, this is still acceptable.

What really moved Wu Xiaoqing was the second news that Wang Youquan said - the search and rescue team found a huge space where there was an invisible device.

According to the guesses of the search and rescue team, the secret of the rebirth of this civilization, as well as the secret of the automatic repair of power towers - and even the secret of automatic repair in outer space, is very likely to be hidden in this invisible space.

"It's a big place, and it's dark...... It's like a big water tank," Wang Youquan clumsily described the appearance of the invisible space, "the search and rescue team said, and voices could still be heard. ”

"Voice?" Wu Xiaoqing looked at his glasses, and the search and rescue team didn't speak to himself - it looked like he should still be on Earth.

If the task is successful, it is natural that the previous large number of * preparatory orders will be interrupted immediately, and the production line of batteries will also be stopped immediately - an additional hour's delay will cost tens of thousands of yuan.

Although the search and rescue team has money, it is not rich enough to use it as a waste. Dealing with these temporary transactional issues is a top priority for search and rescue teams.

And here, for the search and rescue team, it is actually just the end. Since the search and rescue team disrupted their own reading arrangements and let themselves come to the space station, they obviously wanted him to carry out this task himself - his glasses are also the best helper for observing such invisible targets.

Shen Changwen, Yevgeny and Xu Yan are all there, the two professors are discussing the problem excitedly at the moment, Xu Yan is listening stupidly on the side, and he can't say a word. After seeing Wu Xiaoqing and Wang Youquan, he immediately shouted: "Come and have a look!" There is a new discovery, what Lao Maozi just saw, this thing can be used as an invisibility cloak! ”

What Yevgeny discovered was actually not strange, Wu Xiaoqing had discovered it before.

After the short-haired man's phone was returned to the space station, and the images inside were analyzed, Yevgeny quickly discovered the fact that the wave-like optical phenomenon was not the oscillation and distortion of the air itself.

As an expert in the field, Yevgeny was still very familiar with the properties of air, and it was not impossible to produce such visually perceptible light waves in the air, but without exception, it required a huge amount of energy.

For example, when an airplane or rocket is propelled, the strong thermal energy will cause a significant density difference in the air, forming a small area of refraction, causing space to stratify, and even the traces of waves.

But if it's just a cold flying object like a flying sword, turning in a small area at low speed, it's almost impossible to have such a consequence.

Yevgeny's hypothesis that the stealth device was a soft membrane-like material – a hypothesis that has now been partially verified.

Under his command, the short-haired man quickly cut the target area through several other flying swords on the spot, and then included the entire sword in a plastic bag and sent it back untouched.

Shen Changwen had just made detailed observations of several specific areas under the microscope - using special dyeing techniques, they successfully observed that on the surface of the flying sword, there was a very small amount of subtle unknown material stuck on the flying sword, which was not part of the sword body.

Judging from the structural level of these materials, they are obviously not ordinary dusts in the Ascension Realm, and those other things that Shen Changwen and others have already understood.

The material's stealth principle is not yet known, but the basic properties of the material have been confirmed - the material is light, soft, and has a network structure that can be easily cut off and easily rebonded - and looks like a solid, but has the properties of a liquid.

The material is completely transparent in its non-stained state – the refractive index is exactly the same as that of air. That is, if these things were floating in the air of the trapeze world, they would hardly be noticed, let alone studied.

What the two professors are now discussing is the conjecture of the implicit principle of this material, transparency and invisibility, which can be said to be completely different in terms of demand. Stealth requires that the reflected light in the target area be completely blocked – not only occlusion, but also the creation of an identical background.

"On Earth, there are two main ideas for invisible materials......"

"The first is to find a way to fake hidden information – just like a chameleon, to completely merge with the environment and become invisible."

"The second is to refract the light, and put the light behind the invisible object in front of it in some way, changing the direction to block its own light."

"The former is widely used, but more can only be described as camouflage, and the latter is really invisible, but there is almost nothing mature." Although Shen Changwen's major is materials science, he definitely has nothing to do with these things, and the knowledge level of the people who listened to his explanation can only be said to be relatively simple.

In contrast, Yevgeny was more imaginative, and after seeing Wu Xiaoqing, he greeted Wu Xiaoqing and asked him to come over, and then made a judgment: "With my understanding of this civilization, I think it is more of the first one you said - but not a disguise." ”

"Wu Xiaoqing, I remember you once described those illusion-making machines...... This may be instructive for us to study this issue. ”
