Suppose a person is operated on by an evil scientist and his brain is cut off from his body and placed into a vat containing a nutrient solution that keeps his brain tissues alive.

The nerve endings of the brain tissue are connected to a computer, which is programmed to send information to the brain in order to keep it hallucinating that everything is completely normal.

For this person or brain, it seems that everything in the world can be converted into information input, including people, objects, the sky, ...... And so on and so forth, and even the movement of oneself, the feeling of the body.

Even this brain can be fed in or intercepted from memories – the memories of brain surgery are intercepted, and then the various environments and daily routines that he may experience are fed.

It can even be coded to "feel" itself reading such an interesting and ridiculous passage here.

The question then becomes, who can really be sure that they are not in such a situation?

This is the famous "brain in a vat", a hypothetical elaboration by Hilary Putnam in his 1981 book Reason, Truth and History.

For Mo Chen, this hypothesis is actually the advanced effect of spiritual illusion, which belongs to the field that must be involved in the advanced application of illusion.

After the blessing brought by the previous Void Surge, his spiritual illusion enhancement was not as strong as the Void Perception and Flickering Teleportation, but it also became the third powerful skill he mastered.

And in terms of pure effect and importance, it is more powerful and terrifying than the magic ability of perception and movement, and the impact it can cause is relatively more deadly.

Mo Chen had already begun to decide that the next step would be to focus part of his enhancement and enhancement on spiritual illusions.

- The basis of the "brain in a vat" is that everything that a person experiences is ultimately converted into nerve signals in the brain.

The supercomputer transmits the same various neural electrical signals to the brain through nerve endings, and gives the same signal feedback to the signals sent by the brain, so the world experienced by the brain is actually a kind of virtual reality created by the computer.

Mo Chen didn't know much about this, after all, he was not a scientist before or after the crossing.

However, he didn't need to talk about any scientific reasoning in these matters, after all, he had already mastered the realm of magic.

Therefore, he didn't need to understand how supercomputers mimicked neural signals, he only knew that his magic could directly achieve that effect.

From a biological point of view, an individual's perception or judgment of objective existence depends on the stimuli it receives.

Psychic illusions are actually the creation of false feelings at the level of the subject's various sensory perceptions, including sight, hearing, touch, etc., in order to confuse the recipient.

From the recipient's point of view, he needs to interact with the external environment and receive information and stimuli in order to be able to generate cognition and make judgments. Psychic illusions, on the other hand, as unreasonable magic, directly replace the interaction between the subject of the environment and him.

If he is not deluded, then the person may be walking on the street or rowing, but if he is, then he is not actually walking on the street or rowing, but has received the wrong information of confusion.

In other words, he may actually be sitting still or lying in bed, but he does think he is walking down the street or rowing, and he is convinced of it.

Even in his personal false perception, he really went to a certain place and experienced a certain event.

And he will remember the memory of the whole process from beginning to end, and all the feelings are so real.

As for now, all the people in this abandoned conjoined ancient building have fallen into such a wonderful and strange state, because they have all become the recipients of the spiritual illusion spell cast by Mo Chen without exception.

In fact, this conjoined ancient building itself has not changed at all, after all, Mo Chen has no way to change the physical form and the spatial form of the real world.

Therefore, the huge alien lair actually existed only in the imagination of the recipients from beginning to end. Of course, Mo Chen also created a corresponding false image that could be taken, but in the final analysis, it was still false.

Because their sensory perception level has been completely blinded, they are receiving false information from the outside world created by the spiritual illusion that Mo Chen casts.

In this case, as long as the space for actual activities is large enough, then the illusion created by Mo Chen can make it impossible for them or any normal person to distinguish it.

Just like a ghost hitting a wall, even if there is no hallucination, there will be a slight difference in the length of a person's two feet, because there are subtle differences in the body structure of living beings.

For example, the wings of a bird, there are subtle differences in the strength and muscular development of the two wings. There is also a difference in the length and strength of a person's legs, and the distance of such a step will be different.

In a word, the essence of biological motion is circular motion. If there is no goal, the instinctive movement of any living being is a circle.

In the case of hallucinations that directly interfere with the senses, the correction function of the human eye and brain can be said to be non-existent, or the correction signal it gives people is false and confused.

In such a situation, the person will only feel that he still has a sense of direction, but he will not realize that he is actually repeating and going around in vain.

Of course, if they really knew that they were going around in circles, they would not be disturbed, in fact, in their cognition, they were indeed running away in a huge dark labyrinth-like alien lair at the moment, running for their lives like crazy.

Running from the east building to the west building, from the first floor to the seventh floor, desperately running around, running up and down frantically, and crying dad and mother in fright.

In fact, if it were only for these immersive recipients, then it would be enough to have a large hall or room in which they would have no problem wandering around in circles.

However, in order to make the live broadcast effect more realistic, Mo Chen not only created false images that could be taken, but also enlarged the actual space to the entire range of the two conjoined buildings.

It is precisely with such a large enough actual space, when combined with false images, not only can the recipient be frightened into insanity, but even the viewers who are watching the live broadcast cannot tell the truth at all.

If this is a special effect, they feel that the funds are burning from beginning to end, not that the scene is huge or not, but that it is a matter of realism.

Even in the overall dim environment, they can see that from beginning to end, this good show is so real that they can't find any traces of PS, and it is so thrilling that it explodes the audience!

In addition to the dull first half an hour at the beginning, the latter part can simply beat the so-called special effects blockbusters in China.

Even if the plot is a little nonsensical, it's a little incomprehensible, but the special effects and exciting scenes are really good!

However, there are also some more rational fans who have discovered that something is wrong, this should be broadcast in real time, right, how can special effects be added? The anchors also interacted with fans before, and they would also respond to the barrage.

You can see that it is not a pre-recorded image.

Besides, even if it's really pre-recorded and filmed, are they crazy to make this kind of effect? Even if you sell yourself to work to pay off your debts, you can't afford to pay it off for ten lifetimes, right?

Such an unreasonable phenomenon, coupled with the fact that it happened only a few days ago......

That's why the alarm center has received so many calls to the same location.

……

……

"Affect sensory perception, create false images, and convey misinformation...... Is it true that there is something similar to "hypnosis", or is it a state that keeps them awake and dreams? ”

Unlike the two people who were crying their fathers and mothers in the two buildings, desperately running up and down everywhere, a certain initiator was looking for a vacant room by himself to sort out his own experience.

Anyway, the spiritual illusion technique cast is a group effect, and after the Void Realm channel node is opened, these two buildings and a certain range outside are all within the range that Mo Chen's magic ability can pass.

As long as they are not able to successfully escape outside and distance themselves, then it is pointless, and they are still covered by the scope of his mental illusions.

Therefore, Mo Chen didn't need to monitor it all the time, as long as he made sure that the spiritual illusion was always running, creating all kinds of illusions, illusions, and illusions.

It's just that the consumption of mana is a problem, but the void has already descended here, plus his magic power has been strengthened many times, and there is a bone talisman on his body that increases the effect of mana recovery, so there is no need to worry about it at all.

Mo Chen was just seriously summarizing the wonderful experience he had gained after using the mental illusion.

Anyway, the holder of the Outsider Mark has mastered a new magical ability, and although they instinctively understand its effects and effects, they still know it for the most part.

Only after using it yourself can you truly grasp and understand this magical ability, which is something essential.

If you just got the instruction manual when you first mastered it, then in the experience of careful and repeated use, you will naturally read the information brought by the flow of magic and understand some more subtle and hidden secrets.

The route of the magic power, the design idea of the magic ability, and the detailed adjustment of the magic effect...... And so on and so forth, these will become more and more clear as they are used again and again.

It's as if an ancient mirror has been rubbed off the patina, and gradually glows with the clarity it once had. In this process, the user also slowly sees his own reflection in the mirror, so that he has a more accurate and detailed grasp of his own ability.

Mo Chen is like this now, he clearly grasps the possible direction of the advancement of the Spiritual Illusion, or the branch field that can be reached as a springboard.

The first is to continue to improve on the original basic effect until it can create semi-real, real illusions, and the type that can have some kind of interaction with the real world.

The second is that the nature of "hypnosis" continues to improve, which can make people fall asleep quickly, and may operate on memory -

And there is also a special branch here, which is the possibility of dreaming and achieving mastery of dreams.

The last is to directly intervene in the emotional aspect, unlike now, by creating all kinds of illusions and illusions, to give psychological pressure to the recipient, so that they can make up for their own brain and scare themselves, so as to produce fear or something.

Instead, they have developed branch applications such as "fear technique" and "fear aura", which directly and unreasonably let the recipient enter a panic and fear emotional state without any reason.

- In the same way, there are also "courage", "calm", and "rage......

It was precisely because of these considerations that Mo Chen felt that he should devote a considerable part of his attention to the magical ability of spiritual illusion.
