Chapter 577 Vicious


Chapter 577 Vicious

On the dark sea, a huge patrol ship was quietly cutting through the waves.

When the satellite fell, they could only watch from a distance in a safe area.

Looking at the spacecraft that has gathered the fruits of decades of human wisdom, burning and falling into the sea, the fire lit up the sea, splashed huge water, and then disappeared into the darkness little by little...
< br>Everyone on board has the sorrow of being a creature that harms its own kind.

The long row of fireballs looks like an enlarged version of waterfall fireworks. One by one, human modern scientific and technological civilization is brought to the bottom of the sea.

Because the fall area is the sea, they don't need to fire.

Compared with the vigorous confrontation on land, the sea can be said to be quiet and desolate.

After all the satellites disappear, ships on the sea will still patrol around. Each dispersed to deal with emergencies on the sea.

After receiving the news that the spaceship was approaching the border, the captain notified all crew members of first-level combat readiness.

On the sea, the moonlight is not bright enough. The small ship advanced in the boundless sea.

Unconsciously, the calm sea surface became rippled.

The fish were churning, at first there were just a few, but later, the movement was so loud that even the observers on the ship could not ignore it.

The captain quickly received the first officer's notice. "Captain, you'd better come and take a look, there's something strange in the water."

When the captain rushed to the edge of the ship, the water seemed to be boiling, countless fish were splashing on the surface, and there were many more Leap high.

"What's going on?" He frowned and looked deeply for a few times before rushing to the control tower. "Has the seawater temperature increased?"

"No, the temperature is normal." The first mate chased behind and said, "But the sonar detected abnormal fluctuations."

The captain paused. He glanced back at the first mate and continued walking forward, "It shouldn't be an underwater weapon at this time. Could it be Seismic waves? "

"No seismic waves were detected," the first mate said again, "but there are obviously ultrasonic waves from unknown sources in the sea. It should be these ultrasonic waves that cause the fish in the sea to riot."
< br>Animals have a wider acceptance range of sound waves than humans, so they can predict danger in advance.

"Ultrasound?" The captain frowned. Could it be that it was Gro's back trick?

After asking about the frequency, the captain breathed a sigh of relief. It was not yet a threat to people.

But even if it is temporarily harmless, he does not dare to take it lightly.

The frequency is decreasing at a steady rate. If this continues, sooner or later they will be like these fish schools, unable to find a place to stay.

Besides, the marine environment is an important part of the Lanxing ecosystem. If all the fish die, it will be another form of destruction.

The captain quickly contacted several other ships and found that they all encountered similar problems. He did not dare to delay and contacted the general control directly.

"Ultrasound?" Lin Fan looked at the lively sea surface and didn't quite understand.

Her understanding of ultrasonic waves is the small machine used to clean glasses in optical shops.

"Is this thing very harmful?" She looked at the obviously panicked people in the information room and asked John Woo completely out of the situation.

"The sound waves we come into contact with every day can be regarded as harmless waves, so you can't feel it. In fact, sound waves can also be used as weapons." John Woo knew more than Lin Fan, gritting his teeth and frowning .

"So Gro is planning a sonic attack this time?" Lin Fan still doesn't quite understand, "It just relies on sound, can it be used as a weapon?"

She suddenly remembered the roaring noise of square dancing in the park every day. It's so noisy that people's brains hurt, but I seem to understand a little bit. "Do they want to kill us?"

Yes! There is that kind of particularly high-pitched sound that can be unbearable if you listen to it for a long time.

Wu Yusen looked at the ignorant and innocent look on the silly girl's face. He really couldn't say anything serious, so he calmly said.

"Let me explain it to you briefly. When a thing vibrates, it will produce fluctuations in the medium propagation. This is a sound wave."

"The frequency unit of sound wave vibration is Hertz. But the range of sound waves that humans can hear is only between 20 Hz and 20,000 Hz. Below this range, or beyond this range, we cannot hear it."

“Animals are usually more alert than us because their hearing range is wider than ours and they can hear us Inaudible ultrasonic waves. "The resonance caused by long-term sustained fixed-frequency sound waves can cause substantial damage to different materials, but just the kind of sound waves you think of can cause mental damage to people. The essence is resonance.”

“For example?” Lin Fan still didn’t understand.

“For example, an earthquake is when the fluctuations caused by the movement of the earth’s crust are transmitted to the ground and resonate with the surface buildings, resulting in serious consequences.” Wu Yusen said seriously.

"There are also people who make noises at a glass, which will shatter the glass when it reaches a certain frequency. Have you seen it on TV?"

Lin Fan nodded.

“This is also resonance. A loud shout on a snow mountain can cause an avalanche, which is also a resonance effect. A group of people run at the same rhythm, and when a certain frequency is reached, the bridge can be trampled...”

Lin Fan kept nodding. These were real examples he had seen on the news.

"So Gro came here with the purpose of destroying infrastructure this time?" she asked.

"I may not have made it clear. Everything has a resonance frequency that can lead to its destruction." John Woo sighed. "Including people."

Lin Fan's eyes suddenly widened.

“Look at these fish in the sea, they must be in such pain because the frequency is endangering them. In the future, more and more animals will be affected.”

“Humans will be too. Did it break like a glass?" Lin Fan's face was filled with disbelief.

Wu Yusen patted her shoulder to reassure her, "Don't worry, it's not that easy. Animals have complex structures such as bones and internal organs, with different densities and different resonance frequencies. Moreover, the frequency that can harm the human body is already very low. The scene you imagined is not easy to happen.”

To say it is not easy is also relative.

Even if a person does not break like a glass, think about it, if the frequency of bone resonance happens to be reached, the bones in the whole body will vibrate.

Suppose, suppose that such resonance will not cause substantial organ damage to people, but the bones will vibrate like a mobile phone. The feeling is terrifying just thinking about it.

What's more, it can't be without substantial harm.

Moreover, there are countless delicate internal organs in the human body.

A normal punch or fall would land him in the hospital for a long time.

Not to mention this kind of continuous shock...

Lin Fan knew that Wu Yusen's words were to comfort her. If this was what Gro really had in mind, it would be a really cruel move.

Sound waves will cause resonance in various seabeds, on the ground, in snowy mountains, and in bays, causing natural disasters to strike first.

Then, the creatures that survive this large-scale disaster will have to accept the next wave of harm from their own resonance...

How vicious! Vicious!

Due to his own emotional problems, Lin Fan rarely has particularly strong emotions.

But at this moment, she really wanted to get into Gro and smash the bastard who came up with this idea.

This is a planet!

How could they? How dare? !

"Send me the location!" Lin Fan rushed out with red eyes.

After a while, the figure of the star appeared on the big screen and flew high into the sky.

The article about sound waves is not particularly rigorous. Looking up the information has already made me fall down.

Let’s take a look. hey-hey.
