Technology promotes immortality, electrical appliances lead me to counterattack

Chen Jie knew better about the progress of the refrigerator rush. After Dian Yu and the others perfected the automatic alchemy device, they handed it over to Chen Jie to handle.

Along with the automatic alchemy device, there is also an instruction manual, and a letter is attached by the way.

There is no need to explain the instruction manual, the focus is on this letter.

The letter is written in Dian Yu's tone, and the whole article has the attitude of a good student who is tireless and not ashamed to ask questions, eager to get advice from the masters of Danzong.

In fact, as long as you take a closer look, you can understand what Dian Yu and the others said.

Today we refined this automatic alchemy device with our cultivation in the Qi refining period and Foundation building period. In the future, when our cultivation level improves, we may be able to refine better and stronger ones.

It hints at the senior officials of the Alchemy Sect, hurry up and seize us talents to cooperate with us. If you miss us, the alchemy technology that you can survive with patience may shake your position in the cultivation world.

The reason why Dian Yu and the others dare to be so arrogant is actually a large part of the reason is that they have obtained the acquiescence of the head, otherwise they would not dare to shake the big tree.

Moreover, Dian Yu will not leave all the operation links to intelligence. She always believes that no matter how powerful intelligence is, it cannot replace manual work. The core technology and innovation capabilities still come from humans.

After handing over the automatic alchemy device, Wu Yi took one away and went back to the alchemy sect to continue researching, and the studio returned to calm.

Seeing that everyone has nothing important to do right now, Dianyu thinks of what she saw Guanshi Chen was using too much mulberry at the refrigerator press conference, and she associates it with the stereo, to see if she can use it to develop new products.

Hearing that Dian Yu is going to start researching magic tools that can amplify the voice again, it sounds interesting, and everyone is instantly aroused.

Of course, just amplifying the sound is too simple, not enough for them to study for a day.

So Denyu asked whether other interesting functions could be added besides amplifying the sound.

I don't know if they can do something about the sound to make this idea fuller.

According to the usual practice, before the implementation of each new project, the team members will gather together to discuss and create ideas, and collect more wonderful ideas, and this time is no exception.

Sound is a thing that everyone is used to, but if you really want to analyze its nature, few people here may be able to explain it in detail.

Since it is to study magic instruments related to sound, before everyone expresses their opinions, Dian Yu will share with you the knowledge about sound in junior high school physics in his previous life.

Modern people know that the propagation speed of sound depends on the type and state of the medium, but these natives in the cultivation world rarely pay attention to this point.

"According to my understanding of the sound, there may be some differences due to the environment, but it is also my personal push wheel, and you can use it as a reference."

Seeing that Dian Yu started to give everyone a science popularization, everyone sat upright and listened carefully.

"In the air, if you don't consider the influence of humidity, temperature, density and other factors, the sound can travel about one foot in one breath. In solids, the sound travels faster."

Denyu bent his fingers and tapped the table with his knuckles, making a 'frame' sound.

"In general, the speed of sound is related to the material of these media."

Everyone was at a loss when they heard it. Is there such a thing about the sound?Sure enough, they were still too ignorant.

"In addition to the sounds we hear every day, there are also some sounds that are not common or heard."

Doesn't it mean that there is no sound if you can't hear it?
Everyone stared blankly at Dian Yu. Dian Yu knew that they might not be able to understand it intuitively for a while, so he could only give an example.

"It's like the ghost-eating bats we encountered in the foggy forest last time. They can also accurately find their prey in the dark underground palace. It's not that they can see at night, but that they use a sound that we humans cannot receive. Finding prey, we might call it 'sonic'."

"Wow!"

Everyone is star-eyed, junior sister is so amazing!I know so much!

Next, Dianyu introduced some characteristics and applications of ultrasonic and infrasonic waves to everyone, and everyone was dumbfounded.

So the invisible voice can be so strong?
Chen Zifeng did know about the use of voice in the realm of comprehension. After Dian Yu finished speaking, he also shared what he knew with everyone.

"Junior sister, you just mentioned that the vibration frequency of ultrasonic waves and human organs is similar or even the same, and it is easy to resonate with human organs, which is very harmful to the human body and can cause death when it is dangerous."

Although Dianyu had said it just now, but hearing this again, everyone still couldn't help but stand on end.

"Yes, brother. Although I haven't seen it with my own eyes, it is recorded in the classics like this." Dian Yu gave them science popularization, saying that it was from a certain classic.

"I have seen."

Chen Zifeng uttered a word flatly, which startled everyone.

"have you seen?!"

Everyone looked at him in disbelief.

Chen Zifeng nodded solemnly, recalling an incident that happened in his childhood.

At that time, he hadn't entered Jianzong, and went out with the elders of the family. It happened that one of their auction houses was holding an auction, and he followed the elders to watch the fun.

It was also at that time that he knew that there was actually a business selling live mermaids in the cultivation world, and it was still in his own shop.

Although he was young, he told himself deep down: This is wrong!

However, he was too young to do anything at all, he could only watch the hideous monks downstairs, screaming fiercely to bid.

It was also at that time that he saw the cruelty of the cultivation world.

The bidding became more and more fierce, a monk hiding in the corner suddenly jumped up, and he directly hit the chains that imprisoned the mermaid on the stage, trying to rescue the mermaid.

However, he was alone and weak, and he was no match for many human monks. He was quickly beaten to reveal his original shape, and he turned out to be a mermaid.

The two mermaids were caught, and they made the last struggle to activate their innate skills, and began to chant in despair. The voice could penetrate even the barrier set by monks in the out-of-body stage in the auction house.

As the mermaid chanted, the chairs and other items placed around began to vibrate and disintegrate, and the debris was scattered all over the place.

Although the monks who were close were not as fragile as the chairs, they also began to be restless, their eyes were about to crack, and their minds became confused.

Chen Zifeng escaped safely under the protection of his elders and the elder guards hired by them with a lot of money.

But more than half of the cultivators died in the catastrophe that day. I heard that the two mermaids also died in the form of expending their lifespan to activate the strongest attack.

After listening to Chen Zifeng's story, everyone was silent for a long time. They were inexplicably afraid and sad, for the unforeseen future, for the complicated and unpredictable people's hearts, and for the poor mermaid.

Perhaps the only way to solve all problems is to become stronger.

Could a mermaid with ultrasound be a dolphin?
