The first thing is that the kindergarten is going to have a themed course, and Xia Libing's parents bought her a goldfish.

The night before, Lao Xia's father was also happy to explain the body and physiological structure of goldfish to his studious daughter through the information he had queried.

Unexpectedly, when he got up the next morning, he saw that the goldfish had been dismembered by Xiao Lao Xia, and the tool was actually a paper cutter in his study.

Looking at the goldfish that had been dissected, the small internal organs that had been cleaned and neatly placed on a piece of absorbent paper in the kitchen, and his daughter who was carefully observing the structure of the fish, he was stupid.

After Lao Xia's mother got up, she was also frightened, and asked her daughter why she did this.

But the answer was "I want to see it".

After that, Xiao Lao Xia also dissected many small animals at different times, on different occasions, with different tools, and if she bought fresh ingredients at home, as long as she didn't pay attention, she would also find an opportunity to dismember.

Xiao Lao Xia, who has just entered kindergarten, did not show the slightest irritability or crazy mood, and behaved consistently plain and rational, as if she was dismantling not a life, but a toy that was no different from rag dolls and plastic models, which made her parents feel even more frightened.

Lao Xia's parents, whether they reasoned in a soft voice or scolded them angrily, there was no way to make Xiao Lao Xia stop doing those things that seemed very cruel and terrifying to them.

Even Lao Xia's father, who has always been gentle and gentle, once couldn't hold back and slapped his daughter.

Although he regretted it as soon as he finished the fight, holding his daughter and crying, Xiao Lao Xia still didn't show anything, neither cried nor showed the slightest expression of fear, as soon as he let go, he ran to the mirror and observed the redness and swelling on his face sideways.

Lao Xia's father couldn't help but wonder, would she suddenly take a knife and cut her cheeks to see why it was red and swollen?

After that, Lao Xia's parents didn't dare to let their daughter go to kindergarten anymore, so they took them with them and watched her at home.

Soon after, a friend of Lao Xia's father brought his child to play at home, and the child accidentally fell and scraped some skin on his knee.

After Xiao Lao Xia saw this scene, he ran back to the house, and Xia's mother, who had been paying attention to her daughter, immediately followed, but found that Xiao Lao Xia took a small pair of scissors in her dressing box that she didn't know when she hid.

Xia's mother hurriedly stopped her daughter, snatched the small scissors, and asked her what she was going to do, but the answer was a little chilly: "I want to see his knees." ”

So after a night of discussion, Lao Xia's parents decided to continue to take her to "seek medical treatment".

Although they still love their daughter, they don't want her to become a "monster" who can be very murderous and threaten others. In particular, the super high IQ displayed by her daughter will multiply this threat.

But just like last time, I saw various experts at the beginning, did all kinds of inspections and tests, but I couldn't determine what the problem was.

Lao Xia's brain structure is normal and functioning normally, and nine major neurotransmitters, including serotonin, γ-aminobutadenone, norepinephrine, and dopamine, are also normal.

She also did not have obvious symptoms of autism or other known mental and psychological related diseases, and could not be diagnosed, so various institutions, hospitals, experts, and doctors only put forward some conservative "treatment plans", which did not have any effect, and also made Lao Xia's parents feel unreliable.

Then Lao Xia's father found a doctor who had just returned from abroad through a relationship, and he was the main compiler of these medical records. She has a lot of work experience and theoretical knowledge, and after spending a month with Xiao Lao Xia, she proposed a set of treatment plans.

Through FMRI (Functional Magnetic Resonance Imaging) and other related brain function tests, Dr. Li found that although Lao Xia's brain has no obvious damage or defects, it does have some unique patterns in the brain when it is carrying out activities.

The way Lao Xia's brain neural network operates may be slightly different from that of ordinary people, and this difference has led to her unique way of thinking.

Lao Xia can feel the pain normally, but the tolerance for pain is very strong, normal people are pricked by needles, they will subconsciously retract their hands, look at the places that have been pricked, and even scream, although Lao Xia will also stop his hands, but the first reaction is to look at the things that are pricked himself, and then observe the situation of being pricked, although she can feel the pain, but the pain does not make her feel afraid and obvious rejection.

Standing on a high place, she is equally not afraid, not nervous, and even has the intention of throwing something else down, or jumping herself, just to see what happens.

Although she can use language normally and understand the meaning of others, she cannot perceive the emotions of others, and she does not have normal people's emotions and lacks empathy.

Looking at the PDFs, the pictures of the case data that were obviously scanned from paper documents, and the judgments made by Dr. Li, Xiang Kun combined them with the books he had read before to understand them.

The human brain has 80 billion nerve cells, each nerve cell is connected to about 7,000 nerve cells, forming a huge, complex and powerful neural network, human memory, thinking, computing and other brain activities, all need to rely on them to complete, and the generation of emotions is no exception.

Each nerve cell is like an electronic device, such as a computer, mobile phone, etc., with different functions.

Some are only 2 to 4 nanometers between each other, and can transmit electrical signals directly through electrical synapses, just like two devices directly connected, which is very fast.

Others are 20 to 40 nanometers apart, so they need to be signaled through neurotransmitters.

Just like USB flash drives and mobile hard disks, the amount of neurotransmitters is the capacity of the removable memory, and the larger the capacity, the more files can be transmitted.

When a USB flash drive (neurotransmitter) filled with files is plugged into the USB port (receptor) on the target device, the target device begins to interpret the file on it, begins to work according to the system's preset software, and may simultaneously transmit information to other electronic devices on the network to get them to work.

Many psychiatric or psychological disorders, including depression, autism, and schizophrenia, are involved in the production and transmission of neurotransmitters.

Or the USB flash drive does not have enough storage space, or the USB port is too small, the reading problem is wrong, or the electronic device itself is faulty.

But Lao Xia's situation is different from these, it is likely that there are many "electronic devices" in Lao Xia's brain neural network, and the systems and application software on them are different from ordinary people, and the same information files are operated differently after entry.

So Lao Xia has a very high IQ, with strong learning ability, motor ability, reaction speed, and sense of balance, but at the cost of impaired cognition of emotions and emotions.

To put it simply: Lao Xia's brain circuits are not the same as ordinary people.

That Dr. Li observed Xiao Lao Xia for half a month, and after obtaining the consent of Lao Xia's parents, he began to use her methods to "treat" Lao Xia.

Her method is very radical and simple, that is, to starve Lao Xia until she perceives her instinctive fear, and then use this as a starting point to influence her other behaviors, so that she understands what other things must not be done, and what things are done, how other people will feel.

Dr. Li saw it very accurately, for Xiao Lao Xia at that time, hunger and appetite were indeed the best interface for her to cut into other senses.

Seeing this, Xiang Kun finally understood what was going on in the closed room when he first perceived Lao Xia's dream, and knew why Lao Xia was eating in such a "hungry ghost reincarnation" way in his dream.

She was indeed starved, and at a very young age, so starved that she was dying.

But this method did make her understand a lot of information.

One of the prerequisites for Dr. Li to use this method is that Xiao Lao Xia has shown a super high IQ, although it is still very small, there is no obstacle to the communication of many things.

Dr. Li used hunger to teach her what it was like to feel pain and fear of death, and little by little helped her realize her own differences, and made her realize how to integrate into society and other people.

Later, with the help of Dr. Li, Lao Xia did not delay going to school, and since elementary school, she has not looked much different from a "normal person".

Except for not being very talkative.,Always staring at others with big eyes.,Except for a somewhat wooden expression.,There's nothing abnormal about it.。

She began to learn and imitate other people's behaviors and expressions, and tried to connect their outward manifestations with their true intentions to help herself understand other people's emotions.

Xiang Kun also knew why Lao Xia wanted to study psychiatry and psychology, and why he was specially transferred to the Third Hospital of Thorn Tong.

The former is naturally to "treat" herself, or to allow herself to adapt to normal life, and the latter is because she knows that there are several cases in the Third Hospital of Thorn Tree, and some of them are similar to those she had when she was a child. She wanted to see if she could find the same cases as her, and then look for ways to get and perceive normal emotions.

However, during this time, she has confirmed that several cases here are not the same as her situation.

Of course, these contents are not the content of Lao Xia's own medical records, but she marked them herself, and even wrote the basic symptoms of those cases.

Obviously, Lao Xia specially made this document to let him understand his situation.

After reading the PDF file, put the tablet back in the bag, Xiang Kun looked at the soft leather book again, some of the pages in it were obviously old, and even the material was different from the one behind, obviously removed from other books and rebound.

What is written in the previous part is the code of conduct summarized by Lao Xia.

Judging by the changes in the handwriting and the fading degree of the ink, it can be surmised that she must have been making these summaries a long time ago, maybe in junior high school, or even earlier.

The first of the Code of Conduct is:

"Keep smiling. ”

But the second rule is: "The smile needs to be adjusted according to the details of each person's facial features to be natural." ”

The third is related to smiles: "Different smiles need to be applied in different scenarios. ”

It seems that they are all supplements made according to the effect after actual application.

Xiang Kun immediately remembered the scene when she picked up Lao Xia at the Tongshi Town Station, and she showed a weird smile to the college student who was accosting her, which directly scared people.

He couldn't help but put this smile on the little Lao Xia in the photo he saw in the PDF file before, and he suddenly felt extremely happy, and couldn't help grinning silently.

However, after feeling the gaze of Lao Xia next to him, Xiang Kun quickly put away his smile and continued to flip through the soft leather book.

Article 35: "When you are unsure, observe more and talk less." ”

......

Article 113: "The difference between what people say and what they really mean is to be judged in conjunction with their expressions and behavioral habits." ”

......

Article 422: "Sometimes poking a sore spot in the face and saying unfriendly things is a sign of humor. ”

Article 423: "The previous article needs to be used according to the circumstances of the relationship, otherwise there will be a conflict." ”

......

Article 489: "Occasional verbal assault on a familiar person is a sign of closeness. (Note: Currently, only Yang Zhener is eligible)"

......

Article 706: "When chatting, sometimes expressions are more suitable than words. ”

......

The last one is nine hundred and seventy-two:

"In order to gain the trust of others, you can first take the initiative to express your trust. In order to get someone else's secret, you can hand over your own secret first. (Note: for Xiang Kun)"

Xiang Kun couldn't help laughing again, turned around and said, "How did you sum up this criterion?"

Xia Libing said: "Practice. ”

Xiang Kun thought he had finished reading it, and was about to get the document bag, but he found that there was still content behind the book, so he turned the book over, and sure enough, he found that he had turned it from back to front, and it was also densely written.

And these contents turned out to be related to him, all of which were judgments and speculations made by Lao Xia and his various observations.

From speculation about his physical fitness, eating habits, and behavior patterns, to possible movements in various time periods, and the true intentions of various behaviors, the analysis and use of various items, including lyrics, calligraphy, black circles, graffiti, chopsticks, and coins, are six or seven points closer to the truth.

There are many things that Xiang Kun knows that Lao Xia has guessed, but there are many more, and even he is a little surprised that Lao Xia can know.

I have to say that Lao Xia's observation and insight really surprised Xiang Kun. Of course, this also has something to do with the fact that he has no defense against Lao Xia.

Among them, what surprised him the most was that Lao Xia had already noticed the peculiarity of the coin when he first came into contact with the "lucky coin" given to Kun in Nana's room in Tongshi Town.

Normally, according to Xiang Kun's previous inference, other people want to have a connection with his "super-link" or "love infusion", in addition to his approval, the first thing is to trust him enough and be willing to believe in the specialness of the coin.

When he sent Lao Xia the graffiti in the black circle, Lao Xia had already obtained the recognition of his main consciousness and had a "network access permit".

But at that time, when Lao Xia first noticed that the "Super Complex" coin might be peculiar, he didn't even know that it was given to Nana by Xiang Kun, but after knowing this, he thought about it carefully and compared it with other coins, so he became more and more sure that his perception was not an illusion.

Xiang Kun speculated from this that there should be some overlap between his "super-coupling" and "love note" and Lao Xia's way of cognition and thinking about things.

After closing the soft cover, Xiang Kun opened the file bag again.

There is no other information in it, it is all Lao Xia's own medical record documents, and the relevant content of the medical records in the PDF is scanned on it, but these are also photocopied or photographed and printed, not originals, and I think she didn't get these directly from that Dr. Li.

Putting away the medical record documents, Xiang Kun took the black soft leather book and put it on his lap, and muttered for a while before he said slowly: "My situation is actually quite simple......
