In just a few moments, Li Yu felt as if a high-power generator had been installed next to his ear, and the sound was buzzing, almost blowing up his head.

The sound was so loud that it even caused him to have a brief tinnitus.

After ten minutes of forced endurance, the distress caused by the high precision of hearing finally eased, and he found that the clear, noisy sound would only reappear when he focused his attention on one place.

He couldn't help but breathe a sigh of relief, if it was like this all the time, he wouldn't have to sleep that night.

In general, in fact, the human brain has the ability to actively filter information, such as filtering, extracting, and even shielding, and can only accept useful information after training.

For example, when people are shopping, they look at everything, but in fact, they don't remember any details, which room, how many windows, how many people at the door, what decoration, what color, basically don't remember. It is only when people want to pay attention to these things that the relevant information is consciously included by the brain.

Li Yu sat in the room, trying to focus all his attention on hearing, thanks to the brain's powerful information processing ability after evolution, at this moment the various information received by the ear began to be processed in an orderly manner.

After greatly enhanced hearing, it is not only as simple as "listening", but more importantly, how to listen consciously.

The more Li Yu tried, the more interesting he felt, his hearing was like a radar that quickly locked on one sound source after another, which building, which floor, which room, and even which specific location, all of which were presented in his brain in the form of 3D omentum graphics, and the sound source was countless green dots that continued to spread in all directions, and whenever his consciousness was concentrated on a certain green dot, the corresponding sound source would quickly enter his ears.

Half of this magical ability is due to the brain's strong computing ability and information inductive processing ability, if the average person suddenly acquires such a powerful auditory ability, I am afraid that in a few days it will be crazy by these incomprehensible noises.

Like a child who has been given a new toy, he tirelessly searches for all kinds of "prey".

Peeling off little by little in the noisy traffic, I heard a little girl's cry, and my mother's patient comforting voice: "Baby don't cry, don't cry, mom will take you to buy candy to eat." ”

Li Yu was not satisfied, he simply changed his shoes and went downstairs, went to wander on the street, countless voices frantically poured into his ears, and after a few minutes of adaptation, he could finally skillfully filter out all the useless information. As he walked, he focused his attention on a random place, such as a meat stall, and heard a big man with a rough voice bargaining with a middle-aged woman with a red neck, such as in the game hall on the second floor of Creative City, there was a piece of "Street Fighter" music hidden in the crackling button sound, and two children were arguing to play.

All of this is a new and unfamiliar experience for Li Yu.

It wasn't until the end of the night that Li Yu reluctantly rushed home, but he suddenly remembered something.

His [Turtle Breath Gong] had already cultivated to the realm of concentration.

I almost forgot about such an important thing!

Thinking of this, Li Yu simply sat on the bench in the community, calmed down, and entered the cultivation state.

Probably affected by the [hearing] thing, he stayed for more than ten minutes before entering the state of "things and me".

This look simply startled him.

The original "True Qi" with the thickness of a fingernail had turned into the shape of "Liquid True Qi", roughly estimated to be about 10 milliliters, and this injection of liquid soon entered the meridians around his body under the traction of his consciousness.

He only felt that every cell in his body seemed to reveal excitement and joy, and unlike before, this time he cultivated, he could clearly feel that something in the air was quietly integrating into his skin.

"If you're right, this should be energy, right?"

Li Yu recalled the knowledge he had learned in He Jinglong's energy principle class before, and his heart became more and more determined.

The transformation of true qi into energy means that he has officially stepped into the realm of [Martial Artist]!

I'm afraid that in the entire first-year high school group, he will be the first student to become a martial artist.

An hour later, the energy returned to the lower abdominal dantian, and Li Yu exhaled a breath, only to feel refreshed, and his whole body was almost inexhaustible.

He remembered one more thing, and immediately consciously entered the system space to check his "attribute points"

Strength: 10 points

Speed: 8 points

Resistance: 7 points

Energy: 1 point

Energy: 1 point

Sure enough, after cultivating from the [Turtle Breath Gong] to the second stage, his energy column changed from 0 to 1.

Now it seems that he has officially embarked on the path of cultivation.

Just as he was proud, Li Mu's voice suddenly came from his ears.

"Brother, why are you here?"

Li Yu opened his eyes and saw Li Mu carrying a schoolbag and vegetables in his hand, looking at him with a puzzled expression.

"Hah, I'm here to experience life. ”

"There are so many mosquitoes out there, and you're not afraid of being bitten. ”

"It's okay, your brother's cultivation method, even mosquitoes can't sense my existence. ”

"Hehe, you just blow it. Li Mu expressed serious doubts.

Li Yu came to Li Mu's side and said mysteriously: "Tell you quietly, I have cultivated to the realm of martial artists." ”

"Really?"

"Really, when did I lie to you?"

"No, your energy affinity is so low, your cultivation speed should be very slow. Li Mu stared at him innocently with big black jewel-like eyes.

Li Yu pinched her ears angrily: "What do you mean by this? Are you doubting your brother's ability?"

"Pain, pain, pain, of course not! My brother is such a powerful genius, this kind of trivial matter must be easy!" Li Mu immediately changed his words.

After the painful lesson of the first-year high school entrance test, Li Mu is quite sensitive to this kind of problem, for fear that saying the wrong thing will hit his confidence, but this time it is rare that he did not contradict Li Yu.

Li Yu knew what she was referring to, his energy affinity and elemental affinity were all D-level, that is, "poor", which was why after practicing in school for more than half a month, the progress of [Turtle Breath Gong] only increased from 3% to 10%.

The low energy affinity means that the ability of the true qi in the body to attract external energy is much worse, and after the energy is integrated into the bone marrow and muscles, it will imperceptibly improve the strength of the body, and the excess energy will be integrated into the true qi and become a part of the true qi.

When the true qi is completely transformed into "liquid" energy, it means the transformation from "human" to "non-human".

Li Mu saw her brother standing next to her without saying a word, she was a little worried, she asked cautiously, "Brother, why don't we go out for a meal to celebrate?"

Li Yu didn't react.

She shook Li Yu's arm again: "Brother?"

"Huh?"

Only then did Li Yu wake up from his contemplation.

"What did you say?"

"I said would you like to go out for a meal to celebrate?"

"Okay. ”

"Then why didn't you just make a sound?"

"Did you just speak?"

"Yes, can't you hear me screaming so loudly?"
