Listening to the sound, he is a girl, and it sounds pretty good.

Just a few short onomatopoeia were not enough to let Gao Ang determine who it was. He just felt that the sound was very close, as if it was in his ears, making him feel itchy.

"Have you mutated your hearing system?"

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

If the white sphere really improves the human body, it should be in all aspects. It is impossible to say that vision and smell have mutated in other aspects. Leave a hearing system alone and will not mutate? Wouldn't that be unfair?

He has no time to verify the principle of mutation for the time being, he is just curious about this tempting voice.

Turn off the speaker, turn the phone into a vibrating sound, close your eyes high, prick up your ears and start to carefully distinguish the sound.

I heard this sound that I accidentally heard just now. When he focused his attention on his auditory nerves, he immediately felt like he had entered a new world.

The cries of insects, birds and birds, the cheers of wild cats, the funny sound of Erha biting the sofa, and the collision and panting caused by the movement of the two... He experiencing this feeling before was the same "scene" and different experiences when he experimented with smell last time.

Fortunately, he had already gained experience and immediately controlled his auditory nerves to actively cut off a lot of garbage sounds, and focused on finding the moan that made him dream of and his heart beat faster.

These different sounds and smells can be said to be clearly distinguished in his personal perception. Although there are thousands or even tens of thousands of information in his nervous system, he can still accurately find the information he wants. He doesn't know how to explain this phenomenon. To use a metaphor, his brain seems to have become a super brain, which can quickly analyze and process information, and at the same time accurately select the information he wants based on the instructions he issued.

If you look deeper, it will be much more complicated. Gao Ang doesn't want to continue thinking at the moment. What he has to do now is to "chase" to that voice and then see how mutated his hearing is.

When he blocked out other messy information, the sound information became particularly clear, just like a fireflies in the night, or a searchlight in the night, he could clearly ‘see’ the ‘route’ of the sound.

Although the approximate location of this sound has been determined, Gao An still cannot tell where it came from because he has no reference standards.

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

As for why it is rubbing rather than knocking, the answer is very simple, because he is very close to the computer desk, and although the knocking sound is small, if he releases his hearing system, the sound will be absorbed by him, and the effect transmitted to his ears will be amplified n times. The knocking sound at that time may be a thunderclap.

Even though he had greatly reduced the force of groping, the effect of this sound reaching his ears was similar to the effect of his nails slashing straight across the blackboard.

If it were the past, Gao An might have been so scared that he had goose bumps all over his body, but now he has basically no response to this sound, just like the usual sound, it is just a little louder and a little strange.

After visually measuring the distance between himself and his fingers, Gaoang closed his eyes again, and continued to explore the approximate location of the sound.

"Um?"

Gao Ang was a little stunned. The result given by his brain was that the person who made the sound was only 3.5m straight-line distance from him.

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

There is only one person upstairs, that is Xia Weiwei.

After locking the direction, Gao Ang tried to open Xia Weiwei's other sounds to explore, and the sounds that came into his ears became increasingly wrong.

"It sounds quite painful, and there is no 'buzzing' sound..." Gao An eliminated some of his other bad guesses and rubbed his chin.

"I'm going, it's my aunt who is here?"

Reactivate the olfactory ability...

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

This is embarrassing. After a long time, it turned out that it was someone's menstrual period.

Fortunately, no one noticed his embarrassment, Gao Ang closed all his abilities to explore Xia Weiwei, including smell and hearing. If he continued to do so, he was afraid that he would die of embarrassment.

After gaining new special mutant ability, Gao Ann immediately had no intention of continuing to play chess. He greeted his friends and played directly.

Turn off the lights and go to bed, Gao Ang began to explore the ultimate range of his listening skills.

Relax the whole body, let every cell be in a state of relaxation, and then focus your energy on the auditory nerves, and the world in the ears suddenly became lively.

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

Following this step, Gaoang blocked most of the spam information, and in the end there was only a sound that seemed to be there and there was nothing, just like a mosquito screaming, which reached his ears.

Then, the distance model of Xia Weiwei's voice was paired with the distance model of the current voice, and then multiplied by the weakening coefficient caused by decreasing the sound layer by layer, Gao An automatically calculated the ultimate distance of this voice: 713 meters.

This sound sounds like the sound of some kind of animal gnawing, without particularly strong breathing or heartbeat, it should be some kind of small animal.

What you eat should be some kind of hard object that is slightly loose but has a certain texture.

No matter how much information is, Gao An cannot infer it.

"Can you add a sense of smell? If there is odor assistance, you should be able to determine where it is or what animal it is, right?"

With this guess, Gao Yang impatiently opened his olfactory system. His previous test only verified that his olfactory sense of smell was indeed mutated, but he had never done a test like hearing.

He was also unable to be sure whether his mutated sense of smell could smell 700 meters away.

Locking the sound, Gao Ang filtered the most intense smell layer by layer according to the previous steps, and with a rough judgment of the direction, the filtration efficiency this time was much higher. Not long after a while, only a few scents were left emitting from that direction.

It smells rotten and has a rotten smell. This smell contains various components such as hydrogen sulfide, methane, ammonia, etc. The reason why we can draw this conclusion is that these odors exist in Gaoang's memory. From this, we can confirm that the place where the sound is made should be a garbage dump. The reason why it is not a sewer is because Gaoang did not hear the sound of running water.

These odors were almost gone when they were more than 300 meters away from that direction. At this time, Gao Ang had to give up this experiment.

This result is also understandable. Although the transmission of sound will be weakened by adsorption from many objects, relatively speaking, there will be more factors that affect the odor.

The principle of sound transmission is vibration. Theoretically, the vibration of any object will cause resonance of other objects, but the vibration fluctuations caused by different objects will be different depending on the mass and material of different objects, that is, the size of the sound. Theoretically, as long as there is a certain substance that can accept all vibrations, even if it is extremely subtle vibration, you can "hear" all sounds.

The smell is different. The smell is caused by the absorption of certain molecules emitted by the human olfactory nerves by the object. This reaction is transmitted to the human cerebral cortex, and then the smell is determined based on the effects of memory factors since ancient times. If the molecules emitted by the object cannot touch the human olfactory nerves, the smell will no longer exist.

After figuring this out, Gao Ang immediately got up, opened the diary and recorded:

[On June 24, the light rain turned into moderate rain. It suddenly started raining at night, which immediately moistened the slightly dull air.

New mutation effect of the white sphere: hearing mutation, you can hear the ultimate sound 700 meters away;

At the same time, the ultimate range of smell was verified, which was close to about 400 meters;

In addition, the white sphere seems to strengthen the brain's judgment ability and is suspected to form a "super brain".]

In the "Super Brain", Gao Ang put a double quote, and he was not sure whether his brain's current judgment ability was considered a super abilities.

Because he heard and smelled a lot of information, which was stored in his memory bank, and he could even recall every feature of them very clearly.

For example, it is like taking out a small movie that exists in a computer from the D disk one by one.

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

He found that his energy seemed to be much more intense. Although he often stayed up late before, he felt a little tired at that time, but he had no such feeling at all these days.

The reason why he still has to sleep is entirely due to habits, and another reason is that he doesn't want to make himself too different.

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

After the preparation, Gao Ann left a note on the dining table and drove the mini out to buy groceries.

Because it was menstrual period and working too hard and hard, Xia Weiwei felt very uncomfortable. She didn't even want to get up, she just wanted to take a good night's sleep.

But when she thought of her deep blood hatred and those enemies who killed her parents were still at large, she could only force herself to get up, and after dressing neatly, she planned to go out.

When she passed by the open kitchen, she carefully noticed some strange things on the dining table. When she approached, she found the note: "I went to work after eating. There was no braised pork at noon, and it didn't last this week!"

She was so angry that she immediately ran to the high room, but found that there was no one at all, and she didn't reply to send a WeChat message.

At this moment, Gao Qiang was leisurely and carefully experiencing the fun of bargaining with others in the vegetable market, and he could also collect more odors. He discovered that whether he smelled or heard, he had to confirm their whereabouts, he had to have a ‘sample’.

Without samples, his abilities would be useless.
