When Wu Daoan got out of the elevator, she suddenly had a feeling of amazement: what she was looking for was not the busy research room she had imagined before, but a clear blue sky, and she was standing on top of the clouds.

Anyway, clouds are just condensations of water vapor, so how can they bear the weight of people? Of course, this is probably a simulated cloud, not a cloud in nature. And there are four buttons on the cloud under her feet, similar to "up, down, left, right" on the dance machine. Press a button and the clouds will move in that direction. The harder you step on it, the faster the clouds move.

Just as she was researching this novelty, a huge head suddenly appeared out of thin air in front of her. Of course, this is only a three-dimensional projection. The person in the projection had a condescending expression and asked him in the common language of the Terrans: "Why did it take so long to come back?

Wu Daoan was afraid of leaking his mouth, so he just nodded obediently.

The head in front of him nodded and ordered, "Okay, go back to your B5 area and continue working." "Then, the 3D projection was turned off.

Wu Daoan is a little helpless, who knows where the B5 area is. And as far as the eye can see, there is a blue sky and white clouds, and there is no figure. Well, let's just take a casual stroll.

This space is a bit surprisingly vast, and I haven't seen a single figure after walking for half a day, so it's probably something similar to an attached space. According to string theory, there are nine dimensions of space, but six of them are so convoluted that they are imperceptible to human beings and do not affect human life at the macro level. However, when technology reaches a certain level, it will definitely be able to forcibly pull away these extremely curly dimensions. It's like spreading out a crumpled ball of paper, it feels like creating a new space out of thin air, but in essence it's just a full use of the space.

In fact, when the monk cultivates in the later stage, he will also comprehend the law of space. For example, the distance between the breaths of a monk during the Tribulation can span several light years is essentially a temporary folding of space.

Of course, this realm is still far away from our classmate Wu, and she is just coming to see what the hell the Shenyue Empire is up to. It was also a coincidence that as she walked, she actually ran into a robot, and took the initiative to bow when she saw her passing by. She had the mindset of trying. He asked, "How do you get to B5?"

& Citizen Level: 98. Position: Confidential Researcher. Clearance Level Confirmation: M4 Level ......" After the robot scanned Wu Daoan's iris. A bunch of data was reported first, and then he replied: "Area B5 is far away, it is recommended to go to a nearby rail hub for transit, and the location coordinates are ...... It has been set up for you automatically. Good luck with your research. ”

As soon as the robot's metallic sound ended. A row of coordinates appeared on the white cloud under Wu Daoan's feet. Then autonomous driving began. Well, it's high-tech, lazy gospel.

It takes about a minute. Wu Daoan saw a huge aerial platform, which was covered with elevators. In fact, it is more appropriate to say that it is an elevator, it is better to say that it is a short-distance transmission array, but it is just made into the shape of an elevator, and in essence, there is no sling, which door is it an elevator?

However, before taking the elevator, she actually saw a huge three-dimensional projection touch screen in the center of the platform, and a big question mark hung above it. If she understood correctly, it must be a common information desk or something, right? She happened to know nothing about this place, and there was no one around at the moment, so she decisively leaned over, clicked, and began to browse the information on it.

Of course, the high-level scientific and technological civilization is very different from the earth in terms of the basic physical theoretical framework, what is the current earth problems such as the unified force field, gravity and quantum mechanics, the parallel universe, the high-dimensional space time loop, etc., are probably at the middle school physics level on the side of the Shenyue Empire, and even the Planck unit is an outdated concept for them, and it has long been no longer a basic unit.

In fact, Planck's constant is not the same in different planes, which is an important reason for the differences between planes. Moreover, the vacuum in the plane is not a real vacuum, because there will be quantum tidal phenomena, and positive and negative particles will continue to be born and destroyed, which will also hinder the movement of light. Therefore, the current speed of light measured by human beings can only be regarded as the speed of light in the plane, which is far lower than the absolute speed of light in a real absolute vacuum.

Planck's constant, on the other hand, is inferred from the speed of light. As soon as the speed of light changes, so does Planck's constant. The Planck constant, which is deduced from the absolute speed of light, is called the "fundamental constant" by the Shenyue Empire. The particles that exist at this length are also called elementary particles. Of course, the Earth is only inferring that quarks exist, and the length of quarks is astronomical times larger than the basic length, so the technology on Earth is currently only quasi-level 4.

What intrigued Wu Daoan was the classification of the level of scientific and technological civilization. According to the theory of the Shenyue Empire, only the races that detect molecules are called "civilizations". By this definition, the earth belonged to the category of barbarians until the 17th century.

And the deeper a civilization's understanding of particles, the higher the level of science and technology of the civilization.

For example, in the 17th century, human beings on earth discovered molecules through microscopes, and at this time they entered a first-class civilization. In 1909, Rutherford discovered the atom, and at this time entered a level 2 civilization. Later, with the rise of quantum mechanics, protons, neutrons, gluons, and various subons were discovered one after another, and at this time it was considered to have entered a level 3 civilization. With the recent confirmation of the Higgs particle, the Standard Physical model is finally self-consistent, and at this time, it can be regarded as the Great Perfection of Level 3 civilization and begins to enter the next field.

However, the earthlings have only theoretically predicted the existence of quarks, and the classification of quarks has not yet been determined, so it can only be regarded as a quasi-level 4 civilization. If a complete physical model based on various quark-level particles can be established, then it will be considered a level 4 technological civilization is complete.

Of course, there are smaller and more basic particles underneath quarks. And so on. Correspondingly, molecules are also called first-order particles, atoms are second-order particles, proton neutrons are third-order particles, quarks and electron photons are fourth-order particles, and then there are fifth-order particles and sixth-level particles...... And the current level of science and technology of the Shenyue Empire is that it has detected level 9 particles, so it is considered a level 9 scientific and technological civilization, and it will be unknown how many years the earth has been destroyed.

In fact, the vast realm of stars, the plane is like a cow's hair, and there are many civilizations established by human beings everywhere, but there are only two level 9 scientific and technological civilizations. The reason for this lies in the inherent self-destruction factor of civilization. Just as every human being has suicidal tendencies lurking within them, there are elements of self-destruction within every civilization for different reasons.

For example, take the current earth as an example, if before the resources on the planet are exhausted, the scientific and technological level of the earthlings cannot enter the era of space civilization, that is to say, they cannot immigrate to outer space, then the current countries will definitely have to fight for increasingly scarce resources, nuclear bombs are flying all over the sky, and if they don't do well, they will blow themselves back to the barbaric era.

In fact, there has been more than one resource crisis in the history of the earth, and the food crisis has been highlighted in Malthus's time, but the level of scientific and technological development has exceeded the limit of the food crisis, and the so-called crisis has been solved by itself. But the problem is that humanity may not always be lucky enough to use high-speed technology to resolve future crises.

Of course, in addition to internal self-destruction factors, there are also external destruction factors, such as doomsday viruses, foreign enemy invasions, and meteorite impacts. Even the Shenyue Empire, when it had not yet stepped into the space age, was almost wiped out by a virus from an alien planet, and only a small number of people who produced the corresponding antibodies survived, and the civilization regressed for a thousand years, and it took a long time to recover.

Just as Wu Daoan was reading these fresh information carefully, a voice sounded behind him: "What are you doing? Don't go back to work? Long-term absenteeism will lower the level of citizenship, you have to think clearly." ”

> And here it is. Wu Daoan hurriedly closed the information page in front of him and followed the person away. (To be continued......)
