Gu Xiaobai returned to the cabin, took out the headphones, and put them on.

Then he closed his eyes.

The noisy ocean noise filled Gu Xiaobai's mind.

But Gu Xiaobai's brain may be the most powerful sound processing device in the world, and even a supercomputer can't match it.

His consciousness was concentrated, as if there was a layer of veil, filtering out the noise in the noise layer by layer.

The first thing that is filtered out is the sound of the waves.

Then came the sound of other steamers.

The sound of fish swimming in the sea, the sound of whales singing, and other sounds in the water.

In the end, even Zhong Junhao's own voice was filtered out.

At this moment, in Gu Xiaobai's hearing, all other interferences have been eliminated, and only one voice remains.

Under the sea, thousands of meters deep, a voice echoed in Gu Xiaobai's ears.

Its sound, with its slight periodic fluctuations, resembles some kind of peculiar, gently blown instrument.

Sure enough, you've been found!

Under the deep sea, behind the flanks of the three warships, about a distance of more than ten nautical miles, a behemoth is sneaking in the deep sea.

Its speed had dropped to just a few knots, and the entire cabin remained silent, except for the sound of the hull itself.

Several technicians looked at the parameter, and their eyes didn't want to blink.

What is boring parameters for others is the most wonderful thing in the world for them.

No matter how you look at it, this parameter doesn't look like it's true!

Our submarines, how can they be so quiet!

Have you taken dumb pills? No, you can say something!

Not to mention them, even the officers and men on the ship couldn't believe it.

This submarine has also been in service for many years, especially several veteran officers and non-commissioned officers, who have spent more time on this ship than they have spent on shore.

How could they ever have felt that the whole submarine had been so quiet.

It's just been a few months of docking and maintenance, why has there been such a big change?

Reaching out against the wall of the submarine, they felt the slight vibration that was barely touchable, and in their minds, the propeller that stirred the sea but was as smooth as silk came to their minds.

Such a submarine, if it were not for its own death, was detected by someone else's active sonar, who would have caught us?

I didn't expect that we would be alive...... To be able to drive such a submarine!

Mighty!

The whole cabin was quiet, but full of joy.

At this moment, there was a sudden vibration from the hull of the ship, "Boom!"

It was like something, knocked on the hull.

The captain's eyes widened, "What's the situation? Did you hit something? Or did you hit a fish?"

"There is no response from the sonar, there are no obstacles...... Wait, someone is blasting me with active sonar......"

What's going on?

How could anyone bombard me with active sonar?

And so precise?

"We've been discovered!"

The joy and complacency just now were gone, and in the deep sea, in the behemoth hidden in the sea, the officers and men of the navy were already so nervous that they were in a cold sweat!

How could it be discovered!

Our submarine is so quiet that even a sleeping baby can't wake up!

How is that possible? How can it be so easy to be discovered?

Isn't this technology impossible?

Then, they heard another "thump".

Wait, how did you come again?

It's not enough to take the initiative to bang once, do you have to do it again?

It's humiliation!**Naked humiliation!

"Where did the sonar come from?"

"Follow each other's directions!"

"Get ready for battle!"

This is a nuclear submarine, and when it gets serious, its combat effectiveness is also amazing.

(Hey, what's this red button for?)

Active sonar, like the light of a flashlight, exposes itself while discovering others.

Through the intensity and angle of sonar, you can also guess the direction of others.

After being hit by active sonar, they quickly identified the source of the active sonar.

More than ten nautical miles away, Zhong Jun.

Wtf？

We were spotted by a civilian ship?

And at such a distance!

What the hell is this?

On the Zhong Jun, Gu Xiaobai covered the headphones with one hand, and gently tapped a button twice on the console with the other hand.

When he saw the three warships, Gu Xiaobai felt that something was wrong.

Although the "Gu Xiaobai-Pan Guoxiang formula" or "black square formula" is applicable to various propellers, it is most suitable for submarines.

Since three warships have already begun to measure at sea, how come there are no submarines?

It's not scientific!

So Gu Xiaobai came back to look for it, and sure enough, he found it.

Then he said hello with active sonar.

But after these two clicks, Gu Xiaobai suddenly felt, hey, this drum beat......

It's kind of familiar.

In the next second, Gu Xiaobai's fingers had already moved automatically......

"Knock knock!"

At that moment, the blood-boiling drum beat came out of Gu Xiaobai's hand, guiding the surging power from the diesel generator to input into the hydroacoustic converter covering the entire hull of the Zhong Jun, turning into a surging bass and spraying away into the seawater!

At this moment, the entire Zhongjun was shaking, underwater, violent sound changes, causing an instantaneous change in air pressure, creating countless tiny bubbles, as if the sea was boiling.

Some plankton and swimming fish in the vicinity fled in panic.

What is this sound?

Why is it so scary!

Could it be that the landslide is cracking!

No, this is not a landslide, this is Gu Xiaobai's music!

Under the sea, among the submarines, the submarine officers and men were also confused.

What's the situation?

Take the drum beat to beat us?

Hey, wait, this drum beat is very burning, and it's familiar!

What is it?

In the next second, Gu Xiaobai's hands moved on the console.

At this moment, this transducer matrix has just finished debugging the active launch, and it has not yet been connected to Gu Xiaobai's other equipment.

There's no way to play recordings or anything.

But it doesn't matter, having such a console is enough for Gu Xiaobai.

Any musical instrument is nothing more than sound waves!

And isn't such a console also for the purpose of emitting sound waves?

It's just that there are no keys on it, only various frequencies, various waveforms.

But for Gu Xiaobai, it is more intuitive.

In his brain, countless notes were converted into frequencies, forming a complex melodic line.

His hands, like playing a piano, danced on the console.

The ultra-low-frequency sonar, which seems to stop the beating of the heart, becomes the low-frequency of the drums, and the mid-frequency sonar and high-frequency sonar together form the melodic part.

If Zhao Xingsheng was here, he would definitely stare out his eyes, Gu Xiaobai is now using this sonar console as a synthesizer to play!

But who said that the console of this sonar is not just a big synthesizer?

No note is out of date with the sound of different frequencies.

Any timbre is a combination of overtones of different frequencies.

As long as your hand speed is fast enough, you can play anything as a piano!

Even if it's a ship!

That's right, at this moment, Gu Xiaobai is playing a boat!

When the melody sounded, the people in the submarine were dumbfounded.

This melody is all too familiar!

Even those who have not seen outsiders for 365 days a year and 360 days have heard this song!

"Champion Overture"!

We are the champions!

At this moment, the entire Zhongjun was vibrating, and it had turned into an oversized water megaphone.

At that moment, Wang Guanshan's heart was complicated......

We, Zhong Jun, have really become a big boat runner!

However, this feeling is so refreshing!

Suddenly I kind of understand those sports car boys!

On the deck, Jiang Wei was saluting the opposite side with his fellow bodyguards.

Most of them are also veterans, and they empathize with Wang Guanshan's feelings.

At this time, Jiang Wei listened to the rhythm and couldn't hold it anymore.

"Boys, dance to our comrades!"

opened a box, threw out the long knives one by one, and more than a dozen people caught them one by one, stood still on the deck, and then "choked".

Blue sky, blue sea, draw the knife -

Dance!

With this "Champion Overture", with this knife dance, for my comrades-in-arms, I wish you all invincible!
