And this person sitting at home, when he hears the crisp footsteps of the upstairs, will tell that the sound is high heels, and if he has not seen the residents upstairs, he may have in his mind the picture of a young girl walking around with long legs in high heels.

But if you have seen that the upstairs resident is a 50-year-old aunt, then when you hear the sound of high heels, it is a picture of a 50-year-old aunt walking around.

The brain will make up the necessary "brain supplements" based on its own "database", experience, logic and instinct.

So it's one thing to be able to collect sensory information, but it's another thing to be able to really use that information to help the brain make judgments.

The reason why Lin Yu lay directly on the ground was not because there was no chair to move out and no blanket to spread on the ground.

It is because in this kind of reinforced concrete building, in addition to the air, the wall and the ground are the main medium of sound transmission, so lying on the ground and directly touching the ground, it is easier to hear the sound of the whole building.

In hearing all kinds of chaotic sounds, Xiang Kun carefully distinguished, slowly sifted through, starting from the voice closest to him, first downstairs, listening to the voice seemed to be a middle-aged couple, talking about their son who went to college in the north, and the news broadcast on the TV.

To the side, there was silence next door, no footsteps, no sound of electrical appliances, no sound of talking, no sound of breathing, but there was the sound of curtains being blown, it should be that the windows and doors were closed, and the owner did not return.

When he hears footsteps, he can judge where others are in the house, or even what kind of movement trend they are in, based on the structure of his own home and other reference sounds, such as the sound of turning on the faucet, the sound of turning on the gas and igniting the fire, the sound of holding a cup, and when other electrical appliances are turned on.

At the same time, he can also use smell to assist in judgment, for example, when he hears the sound of someone colliding with a spatula or cooking food, he can judge what kind of dish the other person is cooking with the smell of smell.

Moreover, the mutual verification of smell and sound can also help him to determine the location more accurately.

According to the voice of the voice, Lin Yu's newly installed search engine in his mind naturally found out his appearance, height, living situation, family and many other information.

Time passed little by little, and from the outside, the lights in the entire community slowly went out and became less, and the voices and movements of each household gradually became smaller.

He has used sound and smell to "walk" the movement of the whole building, every house. That night, through the sound and smell, he recognized almost everyone, and even knew a lot of "secrets".

Based on the corresponding information, the 3D graphics of the entire building are combined again.

A lot of information is combined again based on the corresponding information stored in the subconscious and the head only.

Arrive at a corresponding message that is not far from the real situation.

If the first two times were physical and hardware reinforcements, this time they were software reinforcements.

Integration and sorting is a qualitative leap.

Lin Yu can be sure that with this newly developed software, he will close his eyes and walk on the crowded street.

can sense the oncoming crowd and vehicles.

And the hardware reinforcement has also been carried out a little, not to mention that Lin Yu's senses are fully opened, and a lot of information can be withstood by the brain together.

No more dizziness or headaches, just know.

It was more than one o'clock in the morning that Lin Yu opened his eyes, and he sat up from the ground and stretched out.

I've been exercising for so long, although my body hasn't moved much? But the speed of the brain can be said to be very fast, building up the 3D graphics of the entire building and the personal information database of each person in the mind.

Lin Yu feels more tired than running 5 kilometers!

Just like after drinking life energy, the physical fitness has been greatly improved, in order to adapt to this quality and not waste the corresponding energy, Lin Yu must pay close attention to exercising.

After the rapid improvement of sensory ability, he needs to train his brain to process the sensory information he receives.

It's like two professional athletes with the same weight and similar muscle content, because of the different sports they are engaged in, the training they carry out, and the way they exert their strength are also different, and the results of their efforts are naturally different.

The punches of professional boxers are naturally heavier than those of professional basketball players, and the ability of professional basketball players to complete basketball actions under the same level of confrontation is definitely stronger than that of professional boxers.

Lin Yu knew that it was useless to just increase his sensory ability, he still needed to practice and know how to apply this powerful sensory ability

The first stage is to collect "samples" of sounds and smells that were not available before, build a "database", and become the instinct of smell and hearing, which can be said to have been completed after two days of exercise, coupled with the emergence of a new software integration system.

The second stage is what he is doing now, how to use sound and smell to help Lin Yu judge the surrounding environment and situation, and become his "super eye".

Don't look at the fact that it takes him five or six hours to "walk" around a building now, and when he gets acquainted with it, maybe only a minute or two, he can quickly locate any location of anyone in the building by sound and smell, and even establish a real-time hologram of the entire building in his brain.

It has been discovered that while his sensory abilities have evolved, his brain has also evolved, and at least now when he is immersed in multiple sounds at the same time, he will no longer have the nausea and dizziness he had at the beginning.

Moreover, Lin Yu is not short of soul energy now, even if the material is not so pure, the purification will continue.

If he finds a way to get his hands on the life energy, he will usher in a high-speed evolution stage until he reaches the next level.

Don't talk about it far away, it's too mythical to talk about the eyes of the sky and the ears of the sky.

The one that is relatively easy to achieve is the super daring man in the movie.

The echolocation in the ears, the super tracking of the sense of smell, this is Lin Yu's early goal, maybe the range will not be as wide as his, but in the case of close range, it will definitely not be inferior to him.

At one o'clock in the evening, some tired heads urged Lin Yu to sleep.

Lying on the bed in the bedroom, I couldn't sleep after tossing and turning, and there was always a sound echoing in my ears, and I could always smell some strange smells in my nose.

The newly installed development software in the brain is extremely active, constantly integrating the information from various senses, and the brain is quite tired, but it can't stop at all, and I don't know how to close these greatly strengthened senses.

"Alas, this is also a shortcoming, I can't sleep because of the impact of information, I feel tired."

ㄟ(▔，▔)ㄏ

After tossing and turning for more than two hours, it was not until late at night that the entire building and the surrounding area basically settled down, and the sound began to decrease significantly, and Lin Yu slowly fell asleep.

A night of strange dreams, constantly appeared, at seven o'clock in the morning Lin Yu was woken up by the sound in his ears, he couldn't sleep anymore, brushed his teeth with a dark circle, and finished washing.

Yawn and go out!

There are still a lot of things to do today, I can't sleep, this kind of small thing to put aside in advance, although it is also a trouble, but it is easy to solve.

Uproot! Move all the little things over here.

Exercise the integration ability of your brain, and try to train this active skill that cannot be turned off into a passive skill.

As well as the newly acquired swordsmanship and sword and shield skills, although the newly-acquired knowledge was deeply engraved in Lin Yu's mind.

The problem is that although the brain clearly remembers this fighting technique, there is a high probability that its body will not be able to do the movements that the brain wants.
