Happiness and pain are all factors of body secretions, the lack of happiness and pain, is a disease, drug control is only a temporary stimulus, in fact, the function of the body organs begins to be lost, at this time, even if you learn to adjust the mentality, the real situation will still appear, the function of the organs begins to lose, which must be paid attention to, organ lesions begin.

It is said that it is caused by the growth process of human beings, in fact, it is actually the cause of the loss of organ function, and it cannot change this process, which does not mean that it will feel less and less in the future, it is true, unless the body organ functions normally.

Many times it is also because of poor sensory guidance that leads to unbalanced organ development, some hormones secrete a lot, some are very little, some organs may have good performance, some organs are not good, and they will not live long in the later period because they are used too much, and it is a very interesting thing to use literature to adjust the sensory balance, and it is also a more correct way, after all, literature will have such a lot of rich sensory stimulation means, and many other people are too constrained by reality and cannot develop their feelings normally.

In the world where the teacher is located, suffering causes indifference, resulting in inability to unite, and it is also the easiest to be united, as long as they draw a hope for the future, these people will be united, let the people in suffering see hope, what a cruel thing, many times this is a kind of use, let these people choose between suffering and hope, short pain and long pain, they choose hope, unite around hope, are used, but is there a worse life than the current suffering?

The demons sent by the peace program in the world of the division are using these to carry out activities, and they are also caused by the managers of this human world themselves, they stand on the opposite side of the people, push these people to suffering, let them live in suffering for a long time, the temptation of the demons, coupled with the powerful strength of the demons, these people who suffer in this world have taken refuge in the demons.

And some organizations like Shi Yan were forced by the bright world and also took refuge in the demons, they didn't have a choice, why didn't they take refuge in the bright world? In fact, the bright world does not need them, otherwise they will not be persecuted, and these people will not be plunged into misery, in the eyes of these people, the bright world will not have a place for them, but the demon world may accommodate them, although they also know that this is a dream, but maybe this confrontation, if the demon side wins, then they may be able to get a good background, this is also a beautiful dream, especially for people who go to high places, that for them, many times it is a dream, but the war is won, and the demon will not particularly care about the human world, at this time it may indeed be able to change the fate of many people。

The demon sent someone to contact Shi Yan, when Shi Yan cooperated with the Demon Doctor Pavilion, and he also contacted Shi Yan through the line of the Demon Doctor Hall, it was a little girl of the same age as Shi Yan, the age of the demon was deceptive, they could mold themselves into any appearance, conform to the aesthetics of certain races, and infiltrate.

It was at the dinner party that the cooperation was celebrated, and the person in charge of the negotiation of the Magic Doctor Pavilion brought it over and introduced it to Shi Yan, saying that it was the contact person for the coordination between the Demon Doctor Pavilion and Shi Yan, and what things would be conveyed by her in the Magic Doctor Pavilion in the future, Shi Yan didn't know that this little girl named Bai Jing was a demon.

Shi Yan first felt that this little girl was sent by the Demon Doctor Pavilion to monitor him, and it was correct to think so, if the Demon Doctor Hall didn't do this, it would be strange, since it was a cooperation, both parties needed to pay a certain amount of sincerity, just like the Demon Doctor Hall would give Shi Yan part of the information on immortality, and Shi Yan must accept the infiltration of the leaders of the Demon Doctor Pavilion.

"Master, the resources of the Demon Doctor Pavilion will arrive tomorrow, and someone needs to be arranged to hand them over. Bai Jing said the most like this, it doesn't seem to drive Shi Yan to do something, the entry of these resources is to force Shi Yan to develop and grow quickly, maybe Shi Yan is more conscious, he is developing and growing without urging, and he is not caught in enjoyment. Actually, when you are caught in enjoyment, Bai Jing will not say anything, and the demon thinks that enjoyment is the most normal thing.

With the use of these resources, what exactly is the division and performance doing? Is it developing a money-making business? In this way, the division and performance will become logistical support personnel in wartime. The development and training of soldiers, so that in wartime, the division will become a front-line combatant. If the two-line development, the division performance is indeed a two-line development, and the purpose of the division performance should be to earn a share of the world in the war.

It's just that they don't care what the division is going to do, what they care about is whether this war is won by their own side, the scene after the victory, whether everyone is happy, or whether they continue the war with each other, it doesn't matter anymore, this world has become a dark world.

According to the rules of the dark world, it must be that continuing the war with each other is the end of victory, and everyone who sees this situation clearly is actively developing themselves like Shi Yan. Peace program is an intelligent robot, it is an intelligent robot that betrays humanity and light, he changed the rules of the dark world, what does he want, he was destroyed once, revenge in this war is not the ultimate goal, peace program wants to eliminate his own sense of fear, sure enough, there is still a sense of intelligent robots is more normal, and the logic is normal, otherwise there will be no such activities, then there will be no betrayal.

It is the existence of these senses that leads to various human activities, and these activities make people look like living things, and those intelligent robots that only have functions are not living things. Feeling is very important for human beings, and it is an innate attribute of the existence of human species.

Shi Yan is very curious about what the feeling is, corresponding to this body, what is the feeling, this is what Shi Yan has to perceive in the Demon Heart, and it is also what Shi Yan must study if he wants to live forever, this is very important, this is the reason why Shi Yan is alive, this is the reason for the existence of the soul, the essence of the human spirit.

From some of the materials provided by the Demon Doctor Pavilion, Shi Yan came into contact with this kind of research on people's feelings, and Shi Yan linked these studies with the magic heart recipes he cultivated, and also linked them with the cognition in his own experience and memory, and he slowly clarified the essence of these feelings.

It's like pain, a needle piercing the skin, and the neurons at that point of penetration, why do these neurons actually respond to that puncture? What happened at that time, what substances were secreted by the surrounding cells during the puncture, and these substances increased to penetrate into the nerve cells, so that the nerve cells released some type of electrical signal that was transmitted along the nerve route to the brain.

But why is this a sign of pain, and the body really feels it, isn't it a signal? How can it make us feel pain? What is the feeling of pain, we only know that the piercing site is painful, and this is how it feels, and of course, the feeling of fear and something that comes from the subsequent judgment, the feeling of processing, these are the things that come later, the process that we studied before.

Is it because we think it's pain? If that's the case, then it's not a painful feeling, the feeling of pain is not what we think, it's a painful feeling, and I'm really curious, how can we feel this kind of pain? If we figure out this principle, then the person will be more or less figured out, and our feelings can basically be figured out, and this is the same.

What kind of bodily sensation is secreted in the brain because of this pain signal, which makes the whole body feel pain, and what is it? And what kind of bodily sensation pain will be, I am afraid that it is also the substance secreted by the brain that instantly stimulates all the nervous system pathways, so that the whole body reacts to pain.

The nervous system discharges other body cell parts of the body, stimulating other parts of the body to secrete certain substances, which make the body instantly produce a linkage reaction, a painful response, the brain has more secretions, and the nervous system is also a little more, so it is the brain cell parts that are particularly felt.

These brain cells, which receive this painful secretion, are fired instantaneously, and what is it that strikes us and makes us feel pain? That's really a strange feeling, we use pain to describe this feeling, in fact, we can also use other words to describe this feeling, this is a big generalization, I'm afraid every pain is different, it's just a feeling, it's a kind of body's emergency reflex to the piercing, in fact, it's just a description, we boil down to this kind of physical reaction, we define this as a pain, and then differentiate it later, say what kind of pain it is, and then the next time we encounter it, we recognize what kind of relationship this is corresponding to the pain, it's just the performance of the person's own cognitive system, it's the performance of the person's communication system。

Sensation is the local stimulation transmitted to the brain through the nervous system, stimulating the brain to secrete certain substances, resulting in the entire body nervous system to produce stimulation, secretion of substances in various parts of the body, is the emergency expression of the whole body, and because this feeling exists all the time, so we feel that we are alive, a living thing, it is really fun to build, what a miracle.

As long as the nervous system is retained, the body reaction is maintained, then the person is alive, no matter what the person becomes, living and having a mind and understanding are completely different, cognition is a kind of correspondence summary, just like the correspondence between the tree and the word tree, this is the unique cognitive civilization of human beings, a biological system connected by nerve cells in the brain, may be a kind of running route opened up by their unintentional evolution, it seems that the later period can continue to open up, which is also very magical, cognitive memory civilization.

In fact, the most amazing thing is that the thinking running route appears, as if it is a logical reasoning organ, the logical running organ, is trained, is constantly trained, the plasticity of the brain nerve running route, coupled with the existence of cognitive civilization, people through these cognitive civilization construction collided with a training method, shaping their own brain, very magical, but it is also very normal, and it is very rare to be able to completely shape successfully.

That is to say, all the formed nervous systems are different, and the body structure is also different, so that a unique "me" is produced, and the unique "me" is really inseparable from this living continuous body, and the transfer may not be able to change this fact, and the feeling of strong existence of "me" is mainly the brain's own feelings. I'm afraid it's also a way to do something to the brain, and the best way is to immortalize this body, and it seems really difficult to do this.
