Chapter 711: Deep Sea Giant!! (asking for monthly ticket)
"It sounds like metal turning!"
"you sure?"
When Gu Ji said this, several people were shocked.
To know.
The movements that passive sonar can hear are very limited, and even submarine sonar operators cannot specifically determine what it is.
The Asian engineer pushed up his black-framed glasses and couldn't help but ask, "Could it be a sperm whale or a deep-sea creature like a giant squid? After all, there are bubbling sounds in the background noise?"
"Impossible. The echoes of marine creatures won't be very crisp. Besides, the normal habitat depth of sperm whales and giant squids is around 1000 meters. The probability of encountering them at 3800 meters is too small."
Although Gu Ji's tone was very firm.
But old Buller still maintained strong doubts.
"Mr. Gould, I admit that you have a lot of adventure experience, but the sonar system is not something that ordinary people can understand by just listening. It requires a very long time of training!"
In fact, it’s no wonder that some people refuse to believe it.
Although sonar can judge the surrounding environment through the emission and rebound of sound waves, it cannot be concretely simulated.
Therefore, we want to determine what the surrounding objects are.
It requires the sonar operator's rich "listening" experience.
For example, if the sound you hear is very crisp and has a drawn-out tone, then there is a high probability that the sound waves have hit a metal object, such as a ship, other submarines, etc.
But if there is a marine creature in front, such as a whale or a school of fish, the sound that bounces back is relatively low and chaotic.
The accumulation of this knowledge requires years of training and accumulation.
But what they don't know is.
The special sonar mark that Gu Ji had just obtained happened to be equipped with an "underwater sound database".
Combined with the additional hearing improvement from the double marks.
without any exaggeration.
His current sound analysis ability is comparable to that of a top submarine sonar operator!
“Slurp…”
"The voiceprint is moving again!"
Suddenly, the long-haired sonar operator pointed at the information display screen.
The sound wave spectrum above began to jitter again, and the interval between the two sound waves shortened again!
"Something's wrong! There's a metal object approaching us!"
Gu Ji's heart skipped a beat.
3800 meters deep in the sea, a metal object that can move, could it be...
"Quick! There are other submarines approaching us! Watch the periscope! 2 o'clock!!"
"what?"
The sonar operator stood there in a daze. He had no idea how this middle-aged man in front of him could determine so much information through a simple noise sonar.
Available in the next second.
Gu Ji slapped him on the shoulder and said, "Go! Now! Captain, operate the power lever immediately! Quick!"
"Do as he says!"
Perhaps affected by his emotions, Old Buller's face also became nervous, and he hurried to the power control area in front.
At this time, Gu Ji put on the monitoring headset completely.
With his eyes half closed, he concentrated all his energy and listened carefully to the ambient noise picked up by the passive sonar.
[Mind Scan], on!
Gu Ji directly used his mind to activate the characteristic skills of the sonar mark.
In an instant.
A translucent grey light screen appeared in front of him. Along with the fluctuation of ambient noise, a picture of flowing sea water wrapping around an oval shape slowly began to emerge.
That's right.
This is the 3D simulated scene where the "Flying Leap" is currently located.
And with the continued fluctuation of bubbling and metallic sounds.
In the picture, there is a long object faintly visible in front of the left side of the submarine, approaching them.
At this moment.
The long-haired sonar soldier questioned under the periscope control console: "I can't see anything. Although the searchlight has a limited range, at the 2 o'clock direction, even the mud on the seabed is not floating!"
"It's changed its position! It's 11 o'clock! It's circling!"
Suddenly, Gu Ji once again keenly noticed that the information display screen and the mind scanning screen changed at the same time.
“Still haven’t seen it!”
The long-haired sonar operator hurriedly turned the periscope, but the result was the same, nothing was found. "And there seems to be an underwater ridge at 11 o'clock. Mr. Gould, are you sure you really understand sonar?"
Speaking of it.
His eyes had left the periscope observation piece and turned to look at Gu Ji, and then at the captain, Old Buller.
As if to say: Is he kidding us?
"Is the ridge at 11 o'clock? If that's the case..."
Unexpectedly, Gu Ji had no time to respond to the other party's doubts, and just muttered the information to himself.
at the same time.
The mental scan image in front of him also updated with a huge ridge line at the 11 o'clock direction.
Unfortunately.
Although the characteristic skills can simulate all sounds and mental ideas.
However, since passive sonar can only receive noise and cannot actively transmit, it can only determine the direction of the target but cannot determine the distance and altitude at all.
"Height, yes! Height!"
Gu Ji's eyes suddenly lit up, as if he had understood something in an instant, and he shouted hurriedly: "It's above us! Old Buller, adjust the angle quickly!"
"coming!"
Although Old Buller had many questions in his mind, he chose to trust Gu Ji for the last time, so he started the motor engine and turned the paddles at the stern of the boat.
As the bow of the boat continued to move upward.
The area illuminated by the searchlight also gradually moved from the underwater mountains directly in front to the sea surface.
"What happened! Why did the submarine suddenly move!"
"Is it repaired now? Can we return to the surface?"
"Hey! Tell us what happened!"
The submarine moved suddenly.
It also scared the tourists outside the control room.
But at this critical moment, neither Gu Ji, Old Buller, nor the sonar operator had the time to pay attention to them.
The only Asian engineer left was the one who picked up the intercom and started to explain to the tourists: "Dear tourists, please don't panic, we are just..."
"The frequency of the sound is getting higher. It's approaching! It's at 11 o'clock!"
"But I didn't find anything!"
"Old Buller, move up, and to the left!"
"Submarine moves up 5, left 10..."
"The frequency is getting faster! Periscope! Periscope!"
"I'm looking! Damn it, still nothing, nothing!!"
While the Asian engineer was calming down the tourists.
Gu Ji urged the two of them one sentence at a time, his speech speed became faster and faster, and the atmosphere became more and more tense.
When the situation became too pressing, the long-haired sonar operator even screamed hysterically.
"Then look for it again! Look carefully for me!!"
Gu Ji also became famous.
Because the sound frequency displayed by the passive sonar has reached a very high value.
Combined with the current node that is approaching the 5-hour survival time of the system.
It means that danger may be getting closer and closer to them!
"No means no! That's the truth!"
The long-haired sonar operator roared and left the periscope observation platform directly. "Mr. Gould, are you sure that the result you heard is accurate..."
"Wait! What's that sound!?"
Suddenly.
Captain Old Buller, who was in charge of driving the boat, suddenly interrupted him.
The quarrel came to an abrupt end!
next second.
There was a huge churning sound of bubbles, which seemed to come from above the submarine.
"Look! What is that!"
"Oh my god! What a huge shadow!"
At the same time, tourists outside the control room also exclaimed.
The long-haired sonar operator had an expression of disbelief on his face, and he sat back in his chair, pressing his eyes to the periscope observation platform.
Just for a moment.
His eyes widened and his heartbeat suddenly accelerated, as if it was about to jump out of his chest.
In his field of vision.
And Gu Ji's mind scanned the light screen.
A huge, dark shadow was approaching rapidly from the upper left side of the head, like a giant underwater beast, pressing forward in an unstoppable manner!
"Damn it! It's a large submarine! Military!!"
"It's coming towards us! Run! Push right at full speed!" Gu Ji suddenly took off his headset and screamed at the top of his lungs.
"Full right, full push!!"
Old Buller's face had already turned completely pale at this moment. He gritted his teeth and shouted while pushing the kinetic energy joystick to the bottom.
In an instant.
A harsh motor noise came from the submarine's stern machinery room.
At full power, the propellers and side thrusters all stirred the water at the highest speed, pushing the Leap to the right with all its might.
At that moment, Gu Ji felt that the entire submarine was like a tumbler that was tipping over.
The bewildered passengers in the cabin were tossed around by the enormous centrifugal force.
"Still getting closer! Still getting closer!! Estimate fifty feet! Forty, thirty-five! Damn it! It's too big, at least seventy or eighty meters long. If it really hits us, we will definitely die!"
The long-haired sonar operator kept reporting the visual estimated distance.
Thirty-five feet, ten meters away!!
And this distance is shortening at a speed visible to the naked eye!
"Thirty! Twenty-five, Captain, getting closer!"
"Stop yelling! Damn it, I've already pushed the power to the limit!!"
Old Buller cursed loudly, but the blue veins on the back of his hands proved that he was extremely anxious at the moment.
However, from the very beginning, the Flying Leap was designed only as a deep-sea submersible and did not have the ability to sail in the ocean, so the motor propulsion power was extremely low.
And this is 3800 meters deep sea.
Although Old Buller had accelerated as hard as he could to avoid the attack, the boat seemed to be stuck in the mud, tightly bound by an invisible force, unable to move forward!
"Twenty! Fifteen!!"
"Old Buller! Dive in! Close to the bottom of the sea!!"
The voice just fell.
Gu Ji suddenly let out a loud laugh.
The muscles on Old Buller's cheeks jumped, and he rejected the idea directly: "No, if we do that, we will hit the dark stone first, and we will be crushed directly!"
"Ten! Nine! Eight..."
"They will hit the rocks just as well! We have to take a gamble! Otherwise we will die! Quick! There is no time!"
"Five, four..."
"Ah! I'm really crazy! I'll listen to you one last time!!"
Faced with the pressure of the death countdown, Old Buller roared and pressed the steering wheel all the way down.
In the blink of an eye, the submarine dived down suddenly.
With a sense of weightlessness, the long-haired sonar operator's expression became more and more distorted. In his dilated pupils, in addition to the pent-up fear, there was also the growing black shadow: "Three, two, one, it's going to crash!"
"Everyone! Hold on tight!!"
“Boom! Buzz!”
Just at the moment when Gu Ji shouted.
A deafening roar echoed on the seabed, as if a giant beast under the sea was roaring.
The Feiyue submarine was like a car being hit by a heavy truck.
Under the huge impact force, the people in the boat seemed to be thrown into another world, their bodies flying in the air, as if they had lost gravity and were being toyed with at will.
The screams and shouts of the tourists echoed in the boat, but were soon drowned out by the huge crash.
They opened their eyes wide in horror and tried to grab something to steady themselves, but everything around them was spinning and flying wildly, making it impossible for them to start.
Just at the last moment when Gu Ji was about to fall into a coma.
He only felt his back hit a sharp edge, and the intense pain brought him back to reality.
Accompanied by a sharp sound of teeth grinding.
The submarine rubbed against the ground and finally crashed into a dark rock.
"Uh-huh..."
"Gurgle...Buzz! Buzz! Buzz!"
Gu Ji covered his back and forced himself to stand up from the ground, which he couldn't tell whether it was the ground or the wall. He shook his head desperately, trying to regain his consciousness as soon as possible.
But the first thing he saw when he opened his eyes.
What you see is the huge steel plate deformed and bulging under your feet.
The control room was completely dark, with only the flashing red light of the alarm and the gurgling sound of water pouring in from nowhere.
"Woo, are you okay..."
"Captain, hiss! My arm!"
at the same time.
Old Buller and the long-haired sonar operator, who were lying on the ground, also woke up one after another.
"Quick! Check the hull! Water is pouring in!!"
Gu Ji hurriedly called for help.
The Asian engineer gritted his teeth, stood up, pulled out a flashlight from the tool bag on his waist, turned it on, and was shocked by the huge bulge below.
No.
To be precise, this should be the left side wall of the Feiyue submarine.
Yes.
The huge impact just now caused the submarine to roll several times in the water, and finally it tilted sideways into the mud on the seabed.
"The carbon fiber shell and the external observation window must be damaged, and the high-strength steel liner has also been severely deformed. The water pressure flows through the broken external window and pours water into the interlayer space. Once the internal window can't withstand the pressure, it will explode at any time. By then, we..."
The Asian engineer became more and more panicked as he spoke.
When one knows that death is really coming, no one will not be afraid.
"We are finished. If a large military submarine launches a torpedo at random, we will all be killed!" The long-haired sonar operator slumped to the ground, as if he had accepted his fate and was waiting for death.
“We still have a chance!!”
Unexpectedly, Gu Ji suddenly grabbed a metal chair leg scattered on the ground and hit the high-strength steel hull of the submarine hard, "Bang bang bang! Bang--! Bang..."
Asian engineers are also in despair.
He looked at Gu Ji's hammering motion and asked in a half-confused and half-mocking tone, "What are you doing, Mr. Gould? You don't think you can knock back the dent in the high-strength steel, do you?"
"Shut up!"
Gu Ji scolded and continued to pound on the steel plate.
But Old Buller opened his eyes slightly wide, "Three short, three long, three short, wait! Are you sending a distress signal to the other party?"
