"Is that really a hallucination?" Lin Bida still couldn't believe it, the feeling was so real, the sky and the earth were upside down in an instant, the scenery on the ground was vicissitudes, the forest turned into yellow sand, that feeling, not only the change in sight, but also the real change between heaven and earth, he could feel the heat from the desert, and he could also feel that everything was almost the same as the real thing, is this an illusion?

"I'm 100% sure it's a hallucination, and the proof is the last sound of those people, as you just said, these people who eventually returned to normal, all gathered in one location, and there was a small canyon, and when the wind blew from other places, it was not very big, and after passing through this long canyon, the sound of the wind was amplified constantly, so that it could finally be heard by people, and because of this, the monkey's hallucination appeared in the ears of these people, and finally they saw through this, Because of this, he was devoured by the illusion and was in a coma until now.

If it was really a plane shift, how could these people still be able to hear the wind? One person may be false, but five people say so, this must be true, as for what you see and feel is so real, this is also normal, when we are asleep, often dreaming and being hurt often will also have a real feeling, but that is actually just an illusion. ”

In film and television dramas, many people will twist their flesh and skin after being suddenly stimulated, and prove that they are awake through pain, not in their sleep, which is actually not right, when people are dreaming, they actually feel pain, but many of this pain comes from psychology, not physical pain, just like some people are naturally afraid of blood, even if they just see a little bit of blood, they will feel uncomfortable, and some people are naturally afraid of acid, as long as they hear words like lemon and grape, The mouth will secrete saliva, this feeling born through the brain, in fact, in the sleep sometimes affects the body, after all, people can feel pain, from two places, one is their own body, the other is the brain, these two parts together to complete the transmission and feeling of pain, and in sleep, although the human skin will not have any feeling, but your other directions will transmit different sensations to you, which is why.

Just like Limpida will feel the heat after seeing the desert, this is actually an illusion of the brain, just like many people, they don't feel hot when they wear clothes on weekdays, but suddenly there is a hurried thing that will sweat profusely, this heat is not because of the change of temperature, but because of the change of mentality, the human heart sometimes has such a great power, he can make people feel the change of temperature invisibly.

So it's actually wrong not to feel pain in your sleep, and many performances in film and television dramas also have a certain amount of falsehood, which Lin Bida doesn't know, listening to Shu Han's explanation at the moment, he immediately suddenly realized, obviously, Shu Han's examples come from life, and no one will study them in detail on weekdays, but when I think about it carefully, it is indeed this truth, Lin Bida asked in surprise: "Then what does this have to do with how we subdue this monkey?" Even if it's a hallucination, there's nothing we can do. ”

"Voice!" Shu Han said, Lin Bida repeated the "voice" in confusion, and then his eyes lit up, and said: "You mean, sound can hinder the appearance of hallucinations?" Shu Han nodded and said: "Yes, within a radius of thousands of miles, except for the Changing Cow, there is no other creature that can get close to this monkey, the only explanation is that the Changing Cow has a reason why the monkey has to tolerate him, that is, the voice, and before those five people fainted, it was also because of the sound of the wind, so they broke through the illusion and saw the truth, and the sound could make the illusion of the monkey completely out of order." ”

"But how can we be sure of the sound of hysteria because of hallucinations?" Lin Bida asked suspiciously, Shu Han smiled and said, "Bida, do you know the audio?" Lin Pida's eyes were full of doubts, obviously he didn't understand this truth, Shu Han said with a smile: "Audio, is the frequency of sound, the reason why people can hear sound is because of the vibration generated by the eardrum in the ear, sound is a frequency in the final analysis, it is a vibration, and it is also a frequency that breaks the illusion."

The sound of the wind, which happens to be the same frequency as the illusion, will resonate, and finally successfully rescue those people from the illusion, but this voice is not accurate, and the bull can find that voice very accurately, and let himself out of the control of the illusion, and now this is what we need to find, Lin Bida, I know you don't understand now, I can find a sound expert to explain this to you, now the top priority is to understand what the frequency of the sound is? “

Shu Han immediately gave his own order, he asked people to find the death row prisoners who were ready to be executed from the cage, let them take a hot air balloon to that canyon, and find out the audio of the stroke in that canyon, this is a very risky thing, after the last accident, the monkey is obviously also likely to know that the wind coming from the canyon may hinder people from listening to the sound of the wind, so these people are likely to never return, so Shu Han found these death row prisoners, Most of them have committed very serious crimes, such as homicide, or treason and other crimes, it is because of this, Shu Han does not have to feel sad for their death, Shu Han promised them, as long as they can successfully bring back those voices, they will be given a reward for reducing their sentences, so that they can live, which is undoubtedly great news for those of them who are already waiting for death, although they will die, but at least there is a glimmer of hope to live, most people know how to choose.

At the same time, Shu Han also asked some of the condemned prisoners to go to the bull to listen to the sound, which is a little difficult, because after the cow released the sound, people died, even if the equipment was brought over, but when the time came, these things could not be recovered, and now the world's audio recorder is not modern advanced, it can only be recorded in real time, and it is impossible to save it for a long time, so even if people find the device at that time, it is impossible to keep any number on the device, so they want to find the sound audio of the cow, and then use this audio to crack the monkey's illusion, this is undoubtedly a difficult thing, Shu Han didn't think that this thing could be successful, but no matter what, he has to give it a try, see if he can collect the sound directly from the bull, if not, he can only rely on the canyon around the monkey itself.

This is much more troublesome, first send someone to collect the sound of the canyon, but this sound, it is also difficult to preserve, so after collecting the sound, you have to wait for these people who collect the sound to recover from hysteria, and then wait for them to wake up, and then record the audio digitally, in the process, it is possible that these participants will all die, or it is possible that when they arrive, there is no wind in the canyon, and it is also possible that with the passage of time, eventually these people have forgotten the frequency recorded at that time.

Of course, there is also an ideal situation, when they arrive at the canyon, the monkey is not there, and then they take a pen and record the audio number of the sound, after all, this is a measurement of an environment, there is time, unlike the ox, when they see the numbers on the audio meter, they are also dead, there is no time to leave any clues.

But it has to be a good situation, if it's a bad situation, then it's the former one, and even after the audio is determined, the matter is not over, this audio is just close to being correct, not completely correct, it is undoubtedly very difficult to rely on this audio to get humans out of the illusion, they also need to debug it again until they find the best audio, so as to completely resist the interference of monkeys, this whole plan, if you are lucky, maybe a year, but if you are not lucky, I am afraid it will take three or five years, which undoubtedly requires tremendous patience.

But it is better to have a breakthrough direction than to be like a headless fly before, at least now Shu Han has proved that this monkey is not invincible, invincible, he also has his own shortcomings, and as long as he has shortcomings, no matter how much time it takes, he can always conquer, not to mention that the Holy Alliance at this time is not easy, the radiation power of the fierce phoenix is not so easy to fade, although after Qiao Xuan's tough measures, now all the personnel infected with radiation within the Holy Alliance have been disposed of, Their bodies are also buried in the ground with cement, but those trace amounts of radiation elements can not be detected by modern machines, and these things will have a profound impact on the future generations of the Holy Alliance, which will contribute to the decline in the fertility rate of a considerable number of people in the Holy Alliance in the future, the increase in the number of deformed children, the increase in the frequency of cancer, etc., these small changes will occur unconsciously, although it is not visible now, but the horror of radiation is also here.

The biggest horror is not death but the unknown, in addition, the large area of radiant land left by the fierce phoenix before leaving is a huge source of pollution, and it also blocks the best passage for the Holy Alliance to go north, which makes Qiao Xuan want to lead the troops north, and he needs to take a detour to be able to pass, and this is separated by the two mountains of Laoshan and Taishan, the place that the fierce phoenix originally occupied is a plain where the two mountains meet, which is suitable for large-scale marching and building railways, and now, they can only go to the mountains, and then find another way out, This will undoubtedly greatly increase the difficulty of the march, not to mention how much pressure the logistics will be under.

So the speed of the Holy Alliance was naturally slowed down, which made Shu Han at least not particularly nervous, and Shu Han's plan was naturally implemented, after all, in the face of a group of death row prisoners, no one would care what they thought, and they were indeed willing to atone for their crimes, at first Shu Han sent people to the bull to see if they could write down the numbers on the audio inverter by hand before they died, but in the end it failed, just now the voice came out, and before there was any change in the audio device, the person died, In the end, the audio tester that Shu Han worked so hard to make was also lost, and he couldn't find it at all, so he could only build a few more ones.

Fortunately, this kind of thing is not difficult to manufacture, just need to get a good magnet and paddles, etc., at the same time, the use of electrical energy has become commonplace, although the battery more than 300 years ago can not be used, but now the chemical capacity of the survival alliance is not what it used to be, the use of those waste batteries, through the chemical extraction of oxygen molecules, and finally these materials are restored and remade, but let the battery reappear in the world, with the battery is a convenient to carry things, it is much easier to use a hot air balloon to carry it, Otherwise, if you bring a set of generators up, then I'm afraid you won't be able to sit on it at all, and the payload of hot air balloons is very limited now.

After all, Shu Han doesn't have any liquid fuel in his hands, that is the fuel that will only be used in modern hot air balloons, and the survival league uses coal, this kind of thing, low burning, and large weight, just to carry enough to fly to the canyon area, it will exceed fifty kilograms of coal, which is equivalent to the weight of a person, if you bring another generator, it is equivalent to the failure of the mission, so the emergence of portable batteries is undoubtedly a great help.

On the other side, Shu Han is also organizing a group of experts, preparing to make audio replica capabilities, in order to facilitate the birth of headphones, and on the other side of the mission, Shu Han sent ten hot air balloons with ten machines to the canyon, but unfortunately, the monkey was very alert, when they arrived, they were immediately found by the monkey, followed by a burst of stuffy sticks, this time they did not return to Joaquin City, but completely disappeared, apparently killed by the monkey.

Just like Shu Han expected, the reason why he didn't kill him before was because he used Lin Bida and others as playthings, just like a cat saw a mouse and wanted to play tricks, but this time the monkey was obviously vigilant, he was afraid that Shu Han and others would find out his secret, so he didn't give Black Iron City any chance at all, so he killed all these people in the forest, so it was very difficult for Shu Han to find them.

This is of course bad news, but at the same time this news undoubtedly proves this, that is, this is indeed the flaw of the monkey, which is undoubtedly an inspiring thing for everyone, and then just go to collect which voice, for this reason, Shu Han once again sent people, this time in addition to the air and the ground, the two directions move together, as long as the sound can be recorded, for this reason, Shu Han spent a lot of manpower and material resources, five consecutive days of uninterrupted sending people, the first is the death row prisoner, Later, he could only select people from the army, and it took more than 500 people to send more than 100 audio devices in, and finally succeeded in bringing out 20 people, one of whom held a blank piece of paper with a number written on it, 637HZ.
