The violent points of light in Xiao Yuan's mind that were controlled in a fixed area and raged irregularly like a violent wind, the movement of this moment became regular, forming a vortex in the shape of a nebula in each controlled area, which was slowly rotating.

"Why is this happening?" Xiao Yuan stood in front of a controlled area, staring at the slowly rotating vortex in the area, thinking about the cause of this phenomenon, "Could it be caused by the chanting just now?" ”

"Huh? It's getting faster and faster! While thinking about it, Xiao Yuan found that the speed of the whirlpool suddenly changed, and it seemed to speed up a lot, and what surprised him was that this change was not continuous, but a kind of jump.

"What is driving these vortices to jump in velocity, and why is it jumping instead of continuously?"

Xiao Yuan was full of doubts, at this moment, his hearing was completely blocked by the brain system, and the chanting of everyone outside was still continuing, but the sound wave was completely inaudible, if his speculation just now was correct, then without the stimulation of the cranial nerve by the sound wave signal, under normal circumstances, this vortex would not be blessed with energy, and it should not be able to speed up again, let alone jump.

"There must be factors that I didn't expect to inject new energy into these vortices and make them jump."

Xiao Yuan quickly made such a judgment and left the place and went to the closest control center to his location, he had to find the source of these energies as soon as possible.

The essence of those vortices is the nerve microcurrent in their brain, no matter how weak the current, its movement will produce a magnetic field, this basic physical common sense, under normal circumstances, the microcurrent in his brain system moves in all directions, so on the microscopic level, these moving microcurrents will produce magnetic fields of various polarities and directions, and macroscopically, these magnetic fields will cancel each other.

But the current situation is different, the rotation direction of all vortices is the same, that is to say, the polarity and direction of the magnetic field produced by these vortices are the same, the magnetic field generated by a whirlpool is macroscopically insignificant, but when thousands of such magnetic fields are superimposed on the spot, its strength is very considerable, and now the rotation of the vortex is still accelerating, then the strength of the magnetic field generated by the current rotation will inevitably increase.

If the vortex continues to accelerate, then when the magnetic field strength reaches a certain level, it is very likely to cause greater damage to the brain system, so it is necessary to immediately understand the root cause of the vortex rotation and take a certain strategy.

Walking into the control center, Xiao Yuan turned on the recorder of the external signal receiving device, the nature of the brain system determines that it will not be a completely closed system, because as a person, Xiao Yuan cannot completely close himself, he will inevitably continue to receive stimuli in the external environment, such as vision, hearing, body touch, etc., all of which will eventually be converted into nerve currents to be received by the brain system.

In fact, any person has the ability to receive these signals, but the analysis of these neurocurrents in the brain's brain is carried out through the innate functions of the brain, and Xiao Yuan's brain has undergone ultimate brain system transformation, and his brain system will process external signals through specially set external signal receiving devices after they are transmitted.

Xiao Yuan is now looking at one of the external signal receiving devices scattered all over the brain system, after the energy signals received by this device will be simply analyzed, all the signals will be classified, and then different signals will be sent to different functional areas of the brain system for processing, such as auditory signals and visual signals will be sent to the auditory processing area and visual processing area respectively for further processing, and the recorder of this receiving device will record the reception of all these signals, forming a file similar to a log.

Xiao Yuan looked at this log file to find out what went wrong at the root, and what caused the originally irregular movement in those controlled areas to become the later vortex regular rotation.

The classification of the log file is very clear, Xiao Yuan directly skipped the visual signal recording area that occupies the largest space, and first focused on the auditory signal recording area, and found that the auditory signal had a high intensity not long ago, and the composite waveform signal input with a very obvious regularity in frequency.

"These signals must come from the chanting that is still going on." Xiao Yuan made such a judgment, but now the brain system has blocked the auditory signals, and the auditory signals in the log have also stopped abruptly at a certain point in time.

Xiao Yuan flipped through the auditory signal recording area, and looked at other signal records, and soon found an unusual signal input source in the subsequent recording, the time starting point of the signal source input is almost synchronized with the obvious regularity of the auditory signal, there are four unusual aspects of this signal, the most important of which is that its basic characteristics show very obvious fluctuations, and its fluctuation frequency and the frequency of the auditory signal are multiples, and the other unusual thing is that Its amplitude was very weak at first, but it soon strengthened to a very high level, the third unusual thing is that after the auditory signal was blocked by the brain system, this signal did not disappear because of it, until Xiao Yuan looked through the records, it still existed, and it was still intensifying, and the last unusual thing was that the source of this signal was unknown.

"Where is this signal coming from?"

Xiao Yuan was eager to know the source of this signal, because it was very likely that this signal was the source of the affected areas, but to determine whether it was or not, it was necessary to figure out the source of this signal.

This signal cannot be generated out of thin air, Xiao Yuan firmly believes this, and at the same time, this signal is not completely clueless, because at this moment, his main consciousness found that even if his hearing was blocked and his chanting stopped, the excitement of his body did not stop because of this, and he was still swaying with everyone, as if he could still hear the chanting of the people around him.

"Obviously, the people around me still have a strong influence on me." Xiao Yuan's subjective consciousness made such a judgment, and passed this judgment to the sub-consciousness who was studying the external signals.

"What is the internal cause of the rhythmic swaying of the body?" After the sub-consciousness has been judged by the main consciousness, he thinks further.

“…… The rhythm of the chanting...... The rhythm of the body swing...... The frequency of the auditory signal...... Frequency of signal from unknown source...... Frequency resonance ......"

"Brainwave resonance!"

Suddenly, Xiao Yuan thought of this word, as if a lightning flashed, splitting all the doubts in front of him at once, and his eyes suddenly opened up.

People are naturally sensitive to frequency and rhythm, the external performance is that people will like music, when they hear a very strong rhythm, the body will involuntarily sway with it, the root cause hidden under these performances is actually brainwave resonance, Xiao Yuan knows this, but just before he figured it out, he ignored this very important fact.

There is no doubt that the people standing in the church have respect for the Elder in Black, and they have absolute trust in him, this trust is similar to religious belief, from this point of view, they can be said to be believers in the Elder in Black, and are willing to accept everything that the Elder in Black expresses, even if they don't understand this expression at all, this kind of trust equivalent to religious belief is the basic condition for their brainwaves to resonate with each other.

The language spoken by the black-clothed elder has an innate rhythm, chanting through a certain sound frequency and rhythm, this specific frequency and rhythm is transmitted to the brains of all believers in the church through hearing, and through the believers' own chorus, this frequency will be strengthened, forming a brainwave resonance in all people, this resonance will have a subtle effect on the brains of believers, and the brain will send signals to the body, so that the body will subconsciously sway with the rhythm, under the combination of inside and outside, The brainwave frequencies of all these people were quickly able to reach a high degree of uniformity, adding to each other and creating an invisible magnetic field in the church.

This magnetic field will be combined with the sound and rhythm to have an impact on the person in it, because the nerve microcurrent in the human brain is essentially no different from ordinary electricity, and the current will show regular movement under the action of the magnetic field, and the movement of cranial nerve current will undoubtedly have a subtle impact on people's emotions.

Under this influence, believers became more and more religious, and newcomers like Xiao Yuan and Chi Xiang would chant uncontrollably and sway their bodies to it.

"Those signals of unknown origin should be this magnetic field formed by the resonance of everyone's brainwaves."

Through frequency comparison, Xiao Yuan can determine this, but he also needs to further confirm whether the vortices in those controlled areas of his brain are formed by the influence of this magnetic field, this confirmation is easy, he only needs to get the frequency of the magnetic field generated when the vortex rotates.

The magnetic field frequency is easy to measure, Xiao Yuan only needs to get the rotation period of the vortex in the controlled area to easily get the magnetic field frequency.

In order to get the cycles of all the rotating vortices, Xiao Yuan issued a global command, after this command was broadcast, soon, the rotational period statistics of the vortices located in various parts of the brain system were continuously gathered, because the rotational periods of each vortex were not exactly the same, so the returned periodic data was not uniform, Xiao Yuan converted these data, and then sorted them by frequency, forming a frequency sequence.

After obtaining this sorting list, Xiao Yuan separated the composite waveforms of the signal sources recorded in the logger log, obtained a series of single sine waves, and sequenced the frequencies of these waves from high to low, and then compared the obtained frequency series with the frequency sequence just now, and it was easy to find the law - the frequency from low to high, the frequency of the magnetic field generated by each vortex will find the frequency of the foreign signal whose frequency is an integer multiple of it, and the waves of different frequencies can produce a basic condition for resonance. It is an integer multiple between the two.

"Sure enough, it's resonance!"

Xiao Yuan was finally able to determine this, resonance can infinitely amplify the originally weak vibration, for example, when a group of soldiers walked across a bridge at a fixed frequency, if their frequency happened to be an integer multiple of the frequency of the bridge vibration, then, as the soldiers walked forward step by step, they would transmit the kinetic energy on their feet to the bridge through resonance, and the most serious consequence that could be produced was the collapse of the bridge.

Resonance is not only generated in mechanical waves, in fact, any field with wave characteristics, including magnetic and electric fields, if the fluctuation frequency is an integer multiple, will produce resonance, in most cases, this resonance is controllable, and can be used to do many wonderful things, such as radio communication and so on.

And at this moment, there is no doubt that the vortex in Xiao Yuan's brain is formed by the magnetic field where the brainwaves of the outside world are infinitely amplified because of the resonance, and the resonance magnetic field of the brainwaves in the outside world is still continuing, so there will still be energy that continues to pass into his brain through resonance, and this energy acts on those vortices in a way that he is not familiar with, so that its energy continues to accumulate.

"This resonance must be stopped, or the consequences will be dire." Xiao Yuan quickly realized this, at this moment, the rotation speed of the vortex in the controllable area has reached a very high level, and from the current situation, the jump of the vortex will still continue, he is worried that the speed of the vortex will increase to a certain extent, and the controlled area will lose control of it, or the superposition of the magnetic field generated by countless vortices will cause irreparable damage to his brain system.

Xiao Yuan thought of a way to stop this resonance from continuing, the first was to stop the old man's chanting, and the second was to change the rotation speed or direction of the vortex to destroy the necessary conditions for the vibration.

The first method is the most direct and effective, but it is not the first choice, because when everyone is in a state of near-madness, his behavior of rushing to stop the old man from chanting will seem very abnormal, and he has to try his best to avoid this abnormality, from this point of view, the second method has become his first choice, but how to change the frequency of those vortices, he needs to think carefully.

"What should I do?"

Xiao Yuan split out the third sub-consciousness, stood near a vortex outside the control center, stared at the vortex, and thought of a way to change the rotation speed of the vortex, but there was only one way - to send the light spots outside the controlled area of the brain system into the controlled area, and make it move in the opposite direction of the vortex's rotation.

"Give it a try."

Xiao Yuan gritted his teeth, and used the highest authority of the brain system he had to issue a command to the brain system, mobilized some light spots in the channel outside the controlled area, and sent them into the controlled area, when entering the controlled area, the direction of movement and the linear velocity direction of the vortex rotation were relative.

Boom, the vortex in the controlled area was hit by external energy, made a loud noise, and the rotation speed was affected, and there was a slight change so that its rotation speed no longer accelerated, and there was a tendency to slow down, but soon the vortex adjusted its rotation speed under the influence of the outside world, and it was able to resonate with the external magnetic field.

"There is a play, but it seems that the impact of stopping one at a time is too small!"

Xiao Yuanyuan was overjoyed to see this, and used the limit that the brain system could reach to split countless sub-consciousnesses, each of which was used to deal with and prevent a whirlpool, and at the same time, one sub-consciousness flew to the height of the brain system to observe the overall situation of the brain system, and another sub-consciousness remained in the control center, responsible for issuing unified commands.

Xiao Yuan looked down below, those vortices were regularly distributed in the brain system, like galaxies in the vast space, extraordinarily magnificent, this magnificence was transmitted to each sub-consciousness through the sub-consciousness above, and also to the sub-consciousness of the control center.

Thinking that this magnificent spectacle was about to be destroyed, Xiao Yuan's subconscious felt a little pity, but this irrational pity could not be Xiao Yuan's almost machine-like rationality at the moment.

"Let's get started!"

This sub-consciousness in the control center issued an order for unified action.

Boom, the whirlpools scattered in the brain system almost simultaneously made a loud noise, and the subconscious standing above saw that the originally bright city of light in the brain system was darkened in this loud noise, in stark contrast to the city of light, the place where those whirlpools were located, but it was magnificent, and for a time it was changed because of the loss of a large number of light spots and darkened around, like bright stars in the sky.

Xiao Yuan could see that after the external light points rushed into the controlled area, the original light points in the vortex collided with these light points, and this collision caused a large number of light points in these whirlpools to escape from the controlled area, forming a wave like a stone entering the water, spreading out to the surroundings.

Countless circles of light mixed together, and soon a huge light curtain was formed, and when this light curtain was formed, it was like a bubble, rapidly expanding, and in the blink of an eye, it came to the front of the subconscious that overlooked the brain system.

"Ahh Xiao Yuan's consciousness was shocked, and he thought about whether this light curtain would cause harm to him, but before the thought fell, the light curtain spread past him, and he looked up and wanted to look up, the light curtain instantly faded and disappeared in the sky.

At the same time as this light curtain disappeared, Xiao Yuan's main consciousness that had been staying outside suddenly found that there seemed to be a gust of wind blowing around him, and then the people who followed the black-clothed elders around him kept chanting and swaying their bodies were as if the movie screen was frozen, and they were strangely quiet, and even their expressions remained the same as when they were singing.

Xiao Yuan's scalp was numb by this situation, and he reached out and pushed Rose beside him, but he didn't want Rose to crook and fall down.

When Rose fell, she bumped into Chi Xiang on the side, plopping down, like dominoes, and a large number of people around Xiao Yuan fell.

"You ......" And at this moment, a trembling voice came into Xiao Yuan's ears, and following the voice, he saw that the black-clothed elder at the head was raising a hand and pointing at him, his face full of incredulity.

"Oh no, my nanobot!" Xiao Yuan said secretly, at this moment, he found that all the nanobots on his body had failed, and the consequence was that his long-changed appearance would inevitably slowly return to his original appearance.

However, something that surprised Xiao Yuan even more happened, only to see the black-clothed elder striding over, knocking many people in the way to the ground without caring at all.

"What are you going to do?" Xiao Yuan saw the old man come to him, took a step back, and asked vigilantly.

The old man was excited, and there were even tears in his eyes, he stopped a step in front of Xiao Yuan, his lips trembled a few times, he wanted to speak but didn't say it in the end, and then he knelt down with a thud and kowtowed hard.
