Evolution from scratch with added points
Chapter 226 0225 Evolved Hearing
"Ultrasound stimulation?"
"Sound waves higher than 20,000 Hz, this has exceeded the upper limit of human hearing!" Chen Jue stared at the panel with excitement.
I originally wanted to stimulate the eyes to further evolve in a dark environment like a cave, but I didn't expect that it accidentally triggered the enhancement of the auditory part.
You know, sound is a vibrating mechanical wave that propagates through a medium.
Sound waves below 20 Hz are called infrasound waves, and those above 20,000 Hz are called ultrasonic waves.
The average human hearing range is between 20 Hz and 20,000 Hz.
Once a sound exceeds this area, ordinary human hearing organs cannot detect the vibration of this sound.
Chen Jue had greatly improved his hearing through ear massage and continuous exercise with Mingtiangu.
The degree of development of hearing has exceeded that of ordinary humans by several times.
The hearing coverage range reaches 100 meters. As long as you are within this distance, even very weak sounds can be detected and captured.
However, Chen Jue had not tried to listen carefully to the ultrasonic waves above 20,000 Hz before.
He may have encountered it in daily life, but it was subconsciously filtered out by his auditory center.
This time I came to the underground cave to explore on a whim, and meeting these bats was a complete accident.
"Yunzhai is really my blessed place."
"If I can stimulate it further, how far can my hearing improve?"
Chen Jue's heart moved. He exited the cave and found a place with a signal. He used his mobile phone to go online and search the bat's vocalizations through the Internet. Sure enough, there were similar natural recordings.
Chen Jue originally planned to download it, but he didn't expect that he would have to recharge as a member.
“Money is really needed everywhere!”
"You have to pay money to listen to a song these days. It's really penetrated by capital." Chen Jue felt helpless and downloaded a few recordings of bat sounds as soon as he became a member.
Then he got into the cave again and expanded these recordings.
Stimulated by the calls of the same kind, the bats roosting in the cave began to fly around and make harsh "squeaking" sounds.
Chen Jue found a place to sit down cross-legged, closed his eyes and used the [Meditation] skill to empty his mind, turning his head slightly to listen carefully to these real bat calls.
Ultrasonic waves exceeding 20,000 Hz are constantly echoing in his tunnel (the cry of a bat reaches up to 120,000 Hz).
Gradually, he felt that the vibrations his eardrums could pick up were getting stronger and stronger.
After he received the ultrasonic baptism for half an hour, a new prompt began to pop up on the panel:
——————
【Ding~】
[Stimulated by the special ultrasonic environment, your hearing organs have evolved adaptively, and your hearing organs have been greatly enhanced. 】
[Your auditory center begins to try to analyze the received sounds in the range of 10 Hz to 30,000 Hz, and your brain’s auditory center is strengthened under high-frequency stimulation. 】
【Physique +0.03】
【Spirit +0.02】
[Congratulations, your hearing has exceeded the original upper limit of the human species! 】
——————
"The attributes are actually amazing!"
Chen Jue's face lit up when he saw the continuous prompts popping up on the panel.
He had previously boldly speculated that environmental stimulation of the body could accelerate the body's evolution and development.
I didn't expect it to be successfully verified by him so quickly.
"It seems that my previous speculations and assumptions about the panel triggering rules were a little too timid and cautious."
"If environmental factors are so important, I can try to artificially simulate a similar special environment!" Chen Jue's heart moved, and inspiration flashed in his mind.
His previous high-intensity exercises were all done through spontaneous movements to improve his attributes.
Except for being stimulated by the underwater environment in the swimming pool, I was not affected by similar environmental factors at other times.
Now that we have figured out the importance of the environment, we only need to try to add environmental factors into the exercise in the future. The improvement effect obtained is definitely 1+1\u003e2.
…
After verifying his idea, Chen Jue was in a good mood.
When he walked out of the cave, he found that his ability to receive sounds from the natural environment had been greatly enhanced.
In the past, he could hear sounds within a hundred meters at most. Beyond a hundred meters, the sound he received would be greatly attenuated.
Trying to listen again, he found that his hearing range had increased to two hundred meters.
It has doubled!
As long as he is within the range of two hundred meters, any disturbance will not escape his ears.
For example, the subtle chirping of insects or the chirping of birds overhead, as well as the whistling of plants in the wind, can be captured very clearly as long as you listen carefully.
Everything seems to be close to my ears, very magical!
"This is just the initial evolution, and the upper limit of hearing has only reached 30,000 Hz."
"If it can be further strengthened and the upper and lower limits can be further developed, wouldn't it be possible to achieve mythical abilities like clairvoyance and wind ear?" Chen Jue felt happy and walked back to the school happily.
Of course, hearing enhancement is not without its drawbacks.
Because the external sounds passively received suddenly increased several times, the content that the brain needs to process also increased significantly.
At first, Chen Jue was a little uncomfortable, but when he walked back to school, he felt a little relieved.
"Fortunately, the mental attributes also increase along with it."
"If I go back to the noisy environment in the city and listen to too much messy noise, won't I become neurasthenic?" Chen Jue muttered in his heart.
Then I think of the ancient Taoist priests and monks who hid in deep mountains and forests when they were practicing monkhood.
In addition to seeking a quiet place far away from the world of mortals, nine times out of ten, one is also afraid that the noise in the world will affect his state of mind in practice.
Although the big cities are bustling and lively, if you live in those high-rise buildings that resemble pigeon cages, it will be difficult to sleep peacefully if you encounter the noisy neighbor's children upstairs.
This is why we often see news on the Internet about buying floor shakers to fight against the neighbors upstairs.
…
After returning to Yunzhai Township School, the students went home from school in groups while basking in the afterglow of the setting sun.
There was constant fighting and laughter along the way, and they were not affected by the previous drug trafficking case at all.
Chen Jue couldn't help but smile when he saw such a harmonious and innocent scene.
With the joint efforts of him and Wu Fang, this rural school began to slowly develop in a good direction.
However, since I returned to a crowded place, my ears began to receive more random sounds.
The sounds of children playing, chewing snacks, and footsteps all rushed into my mind.
He quickly returned to the dormitory to sit cross-legged and meditate. After a while of adapting, Chen Jue calmed down from the noisy sounds.
"Fortunately, you can try active filtering."
"If I hear these voices too much, I probably have to see a psychiatrist." Chen Jue rubbed his slightly swollen temples.
When I went out, I found that the sky outside had completely darkened.
It took him three or four hours to adapt to the evolved hearing situation.
I went downstairs to the cafeteria to have a simple dinner with my girlfriend. While we were chatting about interesting things in the children's class at the dinner table, a young man dressed like a real estate agent and selling insurance broke in from outside the school.
When I asked what the other person did for a living, the young man hesitated and said that he was from a newly opened electrical appliance store in the county, and he came here to distribute flyers to sell electrical appliances such as solar water heaters.
The other party claimed that they had visited several nearby villages, leaving only Yunzhai where they had not finished the distribution.
However, seeing that he looked a little nervous and left in a hurry after sending a leaflet to Principal Chu, Chen Jue muttered a little: "Going to Yunzhai to sell electrical appliances?"
"Isn't this the same as selling combs to bald monks?"
He picked up the promotional leaflet and took a look at it. He unexpectedly found that the dates on it were all printed in September 2022. When he saw that it was a leaflet that had been in stock for a long time, Chen Jue suddenly became a little suspicious.
"There's something wrong with this guy!"
"How can anyone in business send out expired flyers?"
After neatly picking up the food in his bowl, Chen Jue walked out of the cafeteria and came to the playground.
Unexpectedly, before he even walked out of the school gate, he relied on his newly evolved powerful hearing to hear two men with unfamiliar voices talking in low voices under the big tree at the entrance of the village more than a hundred meters away from the school.
One of them happens to be the young man who just entered the school to sell electrical appliances.
"Hiss~"
First there was the sound of smoking, and then a man said: "Did you get the picture?"
"Brother Long was photographed, and my bag just happened to catch them."
"I was handing out flyers in Tazhai before. A few old men there said that there was a male teacher from the school who helped the police solve the case. It should be this man."
"But Brother Long, that female teacher is really beautiful and has a killer figure!"
"If I can catch someone smuggling out of the country, I'm sure my brothers will be happy." After the salesman finished speaking, he laughed obscenely.
"Then we have to wait until Brother Bao and the others are done enjoying themselves before it's our turn!"
"Products of the highest quality like this are probably going to be supplied to the generals."
"Okay, the video has been sent to Brother Bao, and there will be money coming later. If it is too late, the wind will get strong and it will be difficult to cross the river, so we have to go back as soon as possible." The strange man put out the cigarette butts and laughed obscenely.
The two of them pointed at the candid video on their mobile phones and discussed quietly for a moment, and then planned to leave the village and head towards the ropeway.
But as soon as I stepped out of the village, I heard a "whoosh" sound in the air.
With a muffled "dong" sound, a pebble as big as a fist hit the heel of the man named Brother Long, making the man say "Ouch!", staggering forward and falling into the vegetable garden. In the farmland.
"What's wrong?"
Another young man dressed as a salesman was startled. Just as he was about to help his companion, he heard another "whoosh" sound coming from behind.
With a "boom", the second pebble hit his face directly in the philtrum.
In addition to his nose being smashed and crooked, several of his front teeth were knocked out. The young man fell straight into the farmland before he even had time to scream, and his whole body suddenly stopped moving. (End of chapter)
