Listening to the voice, it's a girl, and it's pretty good.

Just a few short onomatopoeia were not enough for Gao Gao to judge who it was, he just felt that the voice was very close, as if it was in his ears, which made his heart itch.

"Could it be that the hearing system has also mutated?"

With the premise of the mutation of the visual system and the olfactory system, Gao Gao was not particularly surprised by his conjecture.

If the white sphere really improves the human body, it should be all-encompassing, and it is impossible to say that the sense of sight and smell and other aspects have been mutated, and a separate hearing system is left unmutated, right?

He didn't have the time to verify the principle of mutation, he was just very curious about this seductive voice.

Turn off the stereo, turn the phone to vibrate, close your eyes high, and prick up your ears to start carefully distinguishing the sound.

The voice he had just overheard, and when he focused his attention on the auditory nerves, he immediately felt like he had entered a new world.

The chirping of insects, insects, birds and birds, the cry of the little wild cat, the teasing of Erha biting the sofa, and the collision and wheezing caused by the movement of the two people...... Disturbing into his ears one after another, this feeling he had experienced before, the same 'scene' and different experience the last time he experimented with smell.

Fortunately, he already had experience, and immediately controlled his auditory nerves to actively cut off a lot of garbage sounds, and concentrated on finding the moaning sound that haunted his soul and his heart beat faster.

These different sounds and smells can be said to be distinct in his personal perception, although there are thousands or even tens of thousands of information in his nervous system, but he can still find the information he wants to find very accurately, this phenomenon he doesn't know how to explain, to use a metaphor, his brain seems to have become a superbrain, can quickly analyze information, process information, and at the same time according to the instructions he sends, accurately pick out the information he wants.

Going deeper, it would be much more complicated, and Gao Gao didn't want to continue thinking about it at the moment, what he had to do now was to 'catch' the voice, and then see how much his hearing had mutated.

When he blocked out the other messy information, the sound information became very clear, like a firefly in the night, or a searchlight in the night, and he could clearly 'see' the 'route' of this sound.

Although the approximate location of the sound had been determined, Gao Gao still couldn't tell where it came from, as he had no reference standard.

Thinking of this, he stretched out his finger and rubbed it lightly on the computer desk.

As for why it is rubbing instead of knocking, the answer is very simple, because he is very close to the computer desk, although the knocking sound is small, but if he lets go of his hearing system, this sound will be absorbed by him, and the effect transmitted to his ears will be amplified N times, and the knocking sound at that time may be a thunderclap.

Even though he had greatly reduced the force of his groping, the effect of this sound reaching his ears was similar to the effect of a fingernail scratching a blackboard.

If it was before, Gao Gao might have been scared with goosebumps all over his body, but now he basically doesn't react to this voice, it's almost the same as the usual sound, it's just a little louder, a little stranger.

After eye-checking the distance between himself and his fingers, Gao Gao closed his eyes again and continued to explore the general direction of the sound.

"Huh?"

Gao Gao was a little stunned, and the result given by his brain was that the person who made the sound was only 3.5M away from him in a straight line.

Looking left and right, looking up and down, Gao Gao was surprised to determine that the sound was coming from upstairs.

There will only be one person upstairs, and that is Xia Weiwei.

After locking the direction, Gao Gao tried to open Xia Weiwei's other sound explorations in this direction, and the sound in his ears became more and more wrong.

"It sounds painful, and there's no 'buzzing' sound...... Gao Gao rubbed his jaw as he dispelled some of his other bad conjectures.

"I'll go, it won't be the eldest aunt coming, right?"

Activate the ability to smell again......

Sure enough, there was a faint smell of blood......

This is embarrassing, and it turns out that it is someone's menstrual period after a long time.

Fortunately, no one noticed his embarrassment, and Gao Yang turned off all the abilities he explored for Xia Weiwei, including smell and hearing, and he was afraid that he would be embarrassed to death if he continued to get it.

After obtaining a new special mutation ability, Gao Gao suddenly had no intention of continuing to play chess, so he said hello to his friends and went straight to the air.

Turn off the lights and go to bed, and Gao begins to explore the extreme range of his hearing.

Relax your whole body, let every cell be in a relaxed state, and then focus on the auditory nerve, and the world in your ears suddenly comes alive.

Block out the most noisy part of the sound, and then remove the loudest of the remaining parts......

According to this step, Gao Gao blocked most of the spam information, and in the end, only a sound like a mosquito screamed in his ears.

Pairing the previous distance model of Xia Weiwei's voice with the distance model of the current sound, and multiplying it by the weakening coefficient caused by the decreasing sound, the extreme distance of the sound is automatically calculated: 713 meters.

The sound sounded like some kind of animal gnawing, there was no particularly strong breathing and heartbeat, it was supposed to be some kind of small animal.

It should be something that is slightly loose, but has a certain texture.

No amount of information can be speculated.

"Is it possible to add a sense of smell? If there is a smell aid, it should be able to determine what place or what kind of animal it is?"

With this guess, Gao Yao impatiently opened his olfactory system, his previous test only verified that his sense of smell was indeed mutated, but a test like hearing had not been done.

He wasn't sure if his mutated sense of smell could smell 700 meters away.

Locking on the sound, Gao Gao filtered the most intense smell layer by layer according to the previous steps, and with the judgment of the approximate direction, the efficiency of this filtration was much higher, and it didn't take long for a few smells to emanate from that direction.

The smell of rancidity, as well as the smell of decay, contains a variety of components such as hydrogen sulfide, methane, ammonia, etc., and the reason for this conclusion is that these smells exist in high memories. From this, it can be determined that the place where the sound came from should be some garbage dump, and the reason why it is not a sewer is because Gao Gao did not hear the sound of running water.

These smells were already close to nothing when they were still more than 300 meters away from that direction, and Gao Gao had to give up the experiment at this time.

This result can also be understood, although the transmission of sound will be weakened by the adsorption of many objects, relatively speaking, the smell will be affected by more factors.

The principle of sound transmission is vibration, theoretically speaking, the vibration of any object will cause the resonance of other objects, but according to the quality and material of different objects, the vibration fluctuations caused are different, that is, the magnitude of the sound. Theoretically, as long as there is a certain substance that can accept all vibrations, even the smallest ones, all sounds can be heard.

The smell is different, the smell is due to the human olfactory nerve absorbs some molecules emitted by the object and makes a certain response, this reaction is transmitted to the human cerebral cortex, and then according to the role of human memory factors since ancient times, it is judged what kind of smell it is. If the molecules emitted by an object cannot touch the olfactory nerve of the human body, the smell will cease to exist.

After figuring out this truth, Gao Gao immediately got up, opened his diary and recorded:

[On June 24, light rain turned to moderate rain. Suddenly it rained in the magic capital at night, which suddenly moistened the slightly dull air.

New mutation effect of the white sphere: the mutation of hearing, which can hear sounds from an extreme distance of 700 meters;

At the same time, the extreme range of the sense of smell is verified, which is close to about 400 meters;

In addition, the white sphere seems to strengthen the brain's ability to make judgments, and it is suspected that it has formed a 'superbrain'. 】

In 'Superbrain', Gao Gao put a double quotation mark, and he wasn't sure if his brain's current judgment ability was superpower.

Because he hears and smells a lot of information, which is stored in his memory bank, he can even recall every characteristic of them very clearly.

For example, it's like flipping out a small movie from a D drive one by one in a computer.

After writing this, Gao Gao took a shower and planned to go to bed.

He found that his energy seemed to be much stronger, although he used to stay up late before, but at that time there would be some fatigue, but these days he didn't feel this way at all.

The reason why he still sleeps is completely out of habit, and another reason is that he doesn't want to be too different.

In the early morning of the next day, Gao Gao got up early in the morning, and according to the video teaching on his mobile phone, he made some blood-replenishing breakfast for Xia Weiwei in advance: egg custard, lotus seed porridge, and a cup of yogurt.

After finishing it, Gao Gao left a note on the dining table, drove the MINI and went out to buy groceries.

Because it was a menstrual period, coupled with the fact that she worked too hard and desperately, Xia Weiwei felt very uncomfortable, she didn't even want to get up, she just wanted to take a good sleep.

But when she thought of her blood feud, and the enemies who killed her parents were still at large, she could only stand up and plan to go out after getting dressed neatly.

When passing by the open kitchen, she noticed something strange on the dining table, and when she got closer, she found the note: "Go to work after eating, there is no braised pork at noon, not this week!"

Angry, she immediately ran to the high room, but found that there was no one at all, and she didn't reply to WeChat.

And at this moment, he is leisurely and leisurely in the vegetable market seriously experiencing the fun of bargaining with others, and by the way, he can collect some more smells, he has found out, whether it is what he smells or hears, if he wants to confirm their whereabouts, there must be a 'sample'.

Without a sample, these abilities of his would be useless.

Just as he put his things away and was about to drive away, he noticed something interesting.
