What Yevgeny mentioned was naturally the Nine Heavens Illusion that Wu Xiaoqing had encountered at the Nine Heavens Gate before.

The operation mode and principle of the Nine Heavens Illusion have been explained very clearly by the search and rescue team before, and the three-dimensional projections inside are naturally artificially created and played.

It's easy to understand.

But if it's just an illusion, it doesn't really trap a person.

The essence of illusion is nothing more than image information, and three-dimensional images are at best optical illusions in the air, and there is no entity in itself.

When the other party is not alert, this simple illusion may still form a visual deception, but once this deception is realized by the other party, the essence of the illusion is actually nothing more than information obscuration.

The so-called three-flavor hallucination is the same thing as using a strong flashlight to shine on the enemy's eyes, which can essentially achieve the same thing, and in some specific environments, such as pure dark spaces, a strong flashlight may be more effective.

What really makes this illusion work is the thin film material that cuts off the illusion's "horizon" and the real world when the Nine Heavens Illusion appears.

Wu Xiaoqing and Yan Xiu had crossed this thin film material many times, but they didn't care about it at the time - they were more concerned about the information in the illusionary world at that time. Looking back now, in fact, this thin film material is the most technical thing in this Nine Heavens Illusion Mirror.

In Wu Xiaoqing's glasses, there is still a video of the time when he saw the appearance of the Nine Heavens Illusion, through slow motion playback, it is easy to see clearly, those huge illusions themselves have appeared at the moment when the Nine Heavens Illusion began to work, but when they first appeared, the background was still very normal, and through the illusion, you can clearly see the island in the distance in the background.

But after only a few seconds, those images were gone.

Obscuring these images is a highly elastic material that gradually spreads from the periphery of the entire "field of vision", and in slow motion, this material gradually spreads and infiltrates as if a large mass of transparent liquid has been splashed on some invisible spherical surface.

But everyone knew that the Ascension Realm itself was a gravityless world, and the area where the Nine Heavens Illusion Realm was located, that is, the outer area of the Nine Heavens Gate, did not have any spherical transparent objects.

So these diffusions, as well as the spherical propagation process, should be the properties of the material itself.

From the beginning, the material seems to be more like a liquid, but if you zoom in on some parts and look closely at the expansion surface of these materials, you will find that it is actually closer to the behavior of a solid.

When a liquid spreads, it usually spreads naturally from a thicker place to a thinner place due to gravity - while in a gravityless environment, because there is no gravity-related gap, it is basically only a large and small water ball formed under the action of liquid tension.

But in the images recorded by Wu Xiaoqing, the appearance of those substances when they diffuse is clearly like a solid material - it is a force from the thin place in the front, and then the thick place in the back is pulled by this force before becoming thinner - the whole process seems to be a liquid expansion, but in fact, it is more like some kind of solid form of activity - like a ball of folded bed sheets and fabric, which is pulled by someone to a corner, and then pulled and shaken away.

The speed of the entire expansion was almost explosive, and within a few seconds, a radius of more than ten kilometers was completely enveloped.

In addition to the picture when this membrane material appeared, there was also the scene when the membrane material was penetrated—that is, when Wu Xiaoqing left the Nine Heavens Illusion Realm.

From Wu Xiaoqing's point of view, the virtual world dominated by the black background suddenly disappeared, and they suddenly left the illusionary world. But when they turned back to look at the illusion world they had just escaped, they found that everything inside was still as usual—all the illusions they could see before were gone, and only those who remained inside could still see clearly.

Yevgeny put forward a speculation about this - the membrane materials themselves do not have any invisible function, but they themselves are some kind of image generation device, which can be understood as some kind of flexible screen.

The so-called invisibility is not some tall distorted light, but a very simple optical simulation.

As many TV commercials do, if the content of a screen blends perfectly with the background behind the screen, and the screen itself goes unnoticed, then the screen is the ideal invisible material.

It is very likely that this film material is still double-layered, and on the outside it is played on the surrounding environmental influence, so that it is completely integrated with the environment without arousing anyone's suspicion, while on the inside, the picture is played diametrically opposite - such as a pure black background. This background color can cut off the spatial connection between the people inside and the outside to the greatest extent - just like in ancient times, when watching Western pictures, you had to make a layer of cloth to cover the viewer's head, and try to keep the lack of light inside.

Cinemas are of a similar design.

And this film material is a kind of thing that specializes in making optical isolation mechanisms for cinemas.

Everyone already knew before that all the magic weapons in the Ascension Realm were actually just some of the electrical appliances used routinely in the original civilization, and the function of the Qianyang Finger was likely to be the laser cutter used by the space station for overhauling equipment, the Xuantie Shield was just an electromagnet, and the spirit stone was just a battery......

According to this, if you deduce it, the so-called Nine Heavens Magic Mirror, the original function is likely to be nothing more than an advanced version of the home theater, a real three-D version of the projector.

And this membrane material, to the original civilization that made these devices, is likely to be just like an ordinary material that the earthlings used when they first invented the picture.

But this material inadvertently – no, should, almost certainly, deliberately – obscure one of the civilization's biggest problems.

That is to say, when Wu Xiaoqing looked back after leaving the Nine Heavens Illusion Realm, and when the short-haired guest saw the empty huge space, they didn't see anything on the surface, but in fact, their "didn't see anything" itself was a kind of illusion created for him by this membrane.

Theoretically, this membrane material could appear anywhere on the planet without being discovered......

Further, if these things were flying around the world and putting corpses everywhere to make sure they weren't discovered, they would have found a lot of them.

In other words, the entire operation of the search and rescue team is likely to be watched by these invisible observers throughout the whole process.

It's just that these observers are not hostile to Wu Xiaoqing - they are not hostile to the world itself. They just do their own thing according to a fixed behavioral logic, for example, release some kind of mechanical insect to corrode and dispose of corpses, collect DNA information about corpses, and put new "human bodies" back into the environment......

Yevgeny's conjecture stunned everyone at the scene.

This explanation, while bizarre, is very much in line with the fact that this civilization exists, because this civilization itself is a captive civilization. They themselves do not have real technology and resources, everything they have, and the current planet is just a cage created for them by the advanced civilization that captives them, but this cage is several times larger than the earth.

Such a large cage naturally needs corresponding "feeding tools", and these invisible existences that automatically dispose of corpses are understood by the concept of earthlings, but they are just tap water, automatic feeding machines, artificial fountains and other facilities in the zoo.

For the flying people of the Ascension Realm, the existence of these facilities is not much different from invisibility.

- Even if the equipment is placed in front of the animals in the zoo, they will not know and understand the principle.

……

Even if people become smarter, only some parts of the brain are changed, and the cerebellum still does not make any progress. Wu Xiaoqing is still clumsy in controlling the flying sword, but fortunately, now they have a group of captives from Qianyangmen, and now they are serving as a driver for Wu Xiaoqing and taking him on a mission with a flying sword, it is a disciple from Qianyangmen.

Previously, Wu Xiaoqing had also carried a flying sword controlled by Yan Xiu, but Yan Xiu's level was ...... Now they are all very clear, the Nine Heavens Gate can be regarded as one of the weakest sects in the entire Ascension Realm, although Yan Xiu is the best in the Nine Heavens Gate, but at best it is only a better looking one in a group of ducks, compared to the Qianyang Gate, a noble breed that belongs to the swan, whether it is the experience of using the flying sword, or the method of use, it is not half a star.

For Wu Xiaoqing, this difference is like the difference between riding someone else's electric car and riding someone else's Formula 1 sports car......

The moment the flying sword took off, Wu Xiaoqing almost felt that his waist tied to the flying sword was about to be torn off, and the oncoming wind followed...... Even though Wu Xiaoqing deliberately wore a motorcycle helmet, he still felt frightened.

At such a speed, it is possible that as long as they accidentally touch any small pebble during their flight, this stone will pierce Wu Xiaoqing's helmet like a bullet, and tear off his skull by the way......

But a master is a master, and when he flew over this way, Wu Xiaoqing found that he had not encountered a single debris during the entire flight - this was the same as the experience of being carried by Yan Xiu, and the helmet was full of constant sand and gravel crashing sounds, but it was much better.

Of course, there are also disadvantages, there are more necessary evasive actions along the way, and all kinds of sharp turns at large angles...... Fortunately, it is a gravity-free environment here, no matter how you turn it, there will be no problems, if you really drive on the ground, it is estimated that even if you give a tank to this Qianyangmen disciple, you can also throw out the tracks......

The efficiency brought by such a high speed is that the short-haired passenger walked for nearly four or five days, and Wu Xiaoqing only took a little more than half a day to arrive, and when he finally arrived at the destination, Wu Xiaoqing was already panicked, if he hadn't taken motion sickness medicine in advance, he would almost vomit on the spot - vomiting in a gravity-free environment is a dangerous action that is life-threatening to the vomiting person.

In stark contrast, the disciple who brought him here seemed to be a little unsatisfied—there were a total of seven people on their trip, and he was responsible for taking Wu Xiaoqing, and he was the slowest of the seven people.

There's no way, Wu Xiaoqing's physical fitness is too poor.

The short-haired guest has been waiting on the island for a long time, and after seeing Wu Xiaoqing arrive, he came to report his work as soon as possible - in fact, there is nothing to report, what should be said should be seen, Wu Xiaoqing has communicated through remote video before, Wu Xiaoqing came in person, the biggest role is just to take the perspective of the search and rescue team - it needs to be seen more clearly and comprehensively, and at the same time, Wu Xiaoqing is also needed to carry out more complex instructions.

For example, the current one: "Let's cut the whole island first." ”

"The whole island? Cut? The short-haired customer almost thought he had misheard.

"Yes, just use the Qianyang finger," Wu Xiaoqing pointed to the magic weapon in his hand and said, "You will perform it yourself." ”

"But this ......" The short-haired man looked at the giant island in front of him that almost covered the world in his eyes, and then looked at the short stick in his hand, and then looked at the dim and irrelevant Void Stone, and really didn't feel this confidence, "The aura in this Void Stone...... Is it possible? ”

"Of course it's not enough," Wu Xiaoqing said, "so I'll bring you a new one," Wu Xiaoqing said, and took out a brand-new Void Stone from his backpack that emitted a dazzling blue light, "I brought a total of two, which must be enough for you." ”
