Chapter 21

When Xiang Kun opened the window, the sound from outside immediately became more and more clear into his ears. The loud and miscellaneous voice made him feel quite uncomfortable and even had tinnitus.

It was not only the sound, but also all kinds of strong irritant smell. He almost had tears and snot running down.

Xiang Kun quickly closed the window again and frowned: the improvement of hearing and smell is too much?

If they are so sensitive, is it not a kind of torture to live in the city?

Fortunately, after a period of forced adaptation, Xiang Kun found that the impact of extremely sensitive hearing and olfactory was soon reduced.

Only when his attention is focused on hearing or smell, the miscellaneous sound and smell information will be clear again.

Just like after drinking blood for the second time, in fact, his hearing has improved to a certain extent. But if he had not closed his eyes on the roof one night and suddenly heard a voice that he thought he couldn't hear, he might not have noticed it.

The human brain will filter or even block the information obtained by the senses, and only receive the information that people want and need.

Compared with the improvement of strength, vision and vital capacity, the improvement of hearing and smell is difficult to quantify and count, or it needs special equipment.

Xiang Kun in his room, closed his eyes, trying to focus all his attention on hearing, receiving all kinds of sound information.

After his hearing was greatly enhanced, the sound information obtained by Xiang Kun and his judgment of the whole time changed greatly. Not only did he enhance all the sounds, but also all kinds of miscellaneous sound information filled his brain. In a short time, he needed to distinguish the sources and properties of various sounds, and for a while, he felt that he could not hear them.

After a long time, Xiang Kun suddenly felt dizzy and felt like vomiting. He quickly opened his eyes, took a long breath and distracted himself.

Do you still can't adapt to the improvement of hearing?

But looking back on what he had just felt, he quickly realized that perhaps it was not because of hearing, but because the brain couldn't cope with too much sound information.

The human brain is always thinking about laziness. Of course, this kind of laziness is actually a means of self-protection.

The sensory organs are collecting information all the time, but these information are always "selected" according to the needs. Most of the time, we see, hear, smell and feel much more than we think.

Just like those pictures of blind spots, at first glance, people often don't find some strange spots. They will only find them after seeing the hints. In fact, those strange spots have been seen by themselves, but they are ignored by the brain.

Now, although Xiang Kun's senses have evolved, and he has received several times as much information, his brain's ability to process such information does not seem to have evolved enough. After all, when he was trained before, he did not receive so many sound signals at the same time.

So after a short break, he changed his mode to Kun and focused only on a single sound.

……

In the sounds of cars, yelling and music coming from outside, Xiang Kun carefully peeled and selected and found the voice closest to him

Ticking, ticking, is that the sound of the toilet tap dripping? No, it's not his tap. It's next door.

There's a noise of the water pipes in the toilet.

A clear shot? Is that the young people upstairs playing gunfight games or watching movies at home?

Vaguely heard someone talking, it seems to be a female voice, but the small hum, not true to hear, can not hear the content.

……

Xiang Kun walked out of his room and walked along the corridor with his eyes narrowed slightly. Then he went down the stairs, searching for the source of the female voice.

This ability to judge the source of sound, also before a few days, he has been focusing on training, now it seems that the effect is still good.

A few minutes later, Xiang Kun finally found the source of the girl's voice. It was not in their building, but in the grocery store opposite. It was the grocer's daughter who was talking to people on the phone.

At this time, Xiang Kun is standing across the street, more than ten meters away from the grocery store, and the daughter of the grocer is on the second floor. She can't see it in sight, and there is a wall.

But Xiang Kun can already hear the conversation of the grocer's daughter.

At this time, the whole world seems to have been pressed to mute, except for the female voice on the phone.

However, this requires a high degree of concentration to Kun. Once he relaxes and diverts his attention - for example, after the grocer's boss says hello to him, the voice from the grocer's daughter becomes a little blurry, because the various kinds and sizes of sounds from other directions will immediately occupy his mind.

But for the moment, Xiang Kun is still very surprised at his listening.

This range is far beyond his expectation.After all, when the body strength was trained before, after drinking blood twice, the improvement was still within the scope of normal people. In addition to the abnormal speed of strength recovery and endurance, the absolute strength did not exceed the level that normal people can achieve.

But now, after only five days of training, Xiang Kun's hearing is far beyond ordinary people's. He doesn't believe that ordinary people can reach this level through training any more.

However, Xiang Kun speculated that maybe he didn't improve his sense organs of hearing and smell too much, but his original ability of sensory organs was not fully developed.

Xiang Kun still accompanied by the night, just like the previous few nights, walked around, testing his hearing and smell that had just been improved through targeted training and mutation.

If Xiang Kun felt fear and worry when he first felt a series of changes in his body, now he is more curious and excited.

After finding that he did not seem to be in danger for the time being, although there was such inconvenience, the improvement of various functions brought about by several mutations still made Xiang Kun hold a more active and active attitude towards the variation of his body. In any case, it is necessary to mutate, so it is better to mutate in the direction he wants?

In recent days, Xiang Kun basically goes all night long. Dozens of streets nearby are already very familiar. But walking on them again tonight has a totally different freshness, just like the feeling when he first went out late at night a few days ago.
