Ballistic Silence of Special Years

Chapter 773 Dark Abyss
At this time, the submarine has slowly floated to a depth of only 30 meters from the sea surface.

Since it was a secret infiltration operation, the submarine's underwater lighting was not turned on, but even if it was turned on, it would be useless, and it could only illuminate such a large area clearly.

At a water depth of 30 meters, even if you stretch out the periscope and look up in bright sunlight, what you see is only hazy, similar to looking through frosted glass.

If it is near the sea, the sea water will still be lawful, just like the dark green emerald blocking the eyes.

If the navigation depth is deeper, the periscope will see a mass of darkness in front of the eyes, after all, the penetration of sunlight in sea water is limited.

Li Zheng followed the team members to the front of the torpedo cabin and was queuing up to enter and prepare to leave the boat.

He felt that his heartbeat was much faster than usual, and he smelled a cold and slightly strange smell in his nose.

Li Zheng stayed on the boat for a few days and knew that this was due to the use of the "oxygen regeneration board".

When the submarine is sailing, if the depth is on the depth of the periscope, the outboard air will be introduced through the underwater intake pipe, and the outboard air will be provided to each cabin through the ventilation system on the submarine.

In addition, there is an oxygen generating device on the boat, which can use electrolysis to produce oxygen for the sailors in each cabin in the boat to breathe.

It’s just that this can only be done when the power is sufficient. If the submarine is always in a state of stealth, or when sailing in a specific sensitive sea area and needs to use electric propulsion to turn off the diesel engine to avoid noise, everything on the boat that is not necessary All power-consuming equipment will be temporarily shut down, such as air conditioners and oxygen generators. At that time, the submarine needs to use something called an "oxygen regeneration board" to supply oxygen.

The chemical composition of this thing is actually very simple, it is potassium oxide or sodium oxide, which can absorb the carbon dioxide exhaled by the crew and release oxygen.

The structure of the "oxygen regeneration device" is actually very simple. It looks a bit like a toaster for toasting slices of bread. Of course, the size is much larger. The "oxygen regeneration medicine board" is in the shape of a gypsum board. Just put it in the tank of "Oxygen Regenerator".

Each cabin of the submarine has a carbon dioxide analyzer. When the carbon dioxide concentration reaches 0.8%, the "oxygen regeneration device" will be activated.

The team consisted of 12 people, divided into four groups of three and lined up to enter the cabin together.

A group of three is also particular.

Two people can enter a torpedo tube at a time, and two people must be responsible for the safety of a tube at the same time.

Therefore, in the three-person team, there is one "rear" on the two-person line, assisting the fish operator in the torpedo cabin to take on the role of safety officer. The safety officer and the fish operator behind the wall will work together to depressurize and open the torpedo tube valve cover, pulling the distressed personnel out of the inside to avoid accidents.

After the first two groups have successfully exited the cabin, the remaining two crew members will enter a torpedo tube and climb out from it, while the two fish operators will work together to tackle a tube.

Xiao Jun deliberately stayed in Li Zheng and Hou Jun's group this time.

After all, both of them are newcomers, Hou Jun can say that whether Li Zheng can climb out is a problem.

This training is brutal.

Xiao Jun has seen soldiers who couldn't climb out of the pipe no matter how hard they tried.

The kind of fear that can't be restrained, and finally has to give up.

Many people are okay when they climb into the pipe, but they are most likely to have problems when the back gate is closed and the water is injected.

Because the pressure will slowly rise during water injection, and the pressure on the human body will increase. Taking the current depth of 30 meters as an example, the pressure will be four times greater than that of the water surface!
In addition, the torpedo tube is eight meters long and the caliber is only 53 centimeters. When a person is wearing a diving suit and equipment to stay inside, it is completely like being locked alive in an iron coffin, which is still a very narrow iron coffin that is difficult to turn around.

Normal people can hardly bear this kind of fear, let alone Li Zheng, who once had a mental disorder.

Li Zheng and Hou Jun's team was in the middle.

The reason why it is arranged in the middle is also the result of Xiao Jun's careful consideration.

At least the people in front can get out of the cabin smoothly, which is more or less an encouragement to the group behind.

Every year when newcomers do this kind of practice, they will be placed in the middle.

The first two groups got out of the cabin very smoothly.

It was Li Zheng's turn.

"Don't be dazed, hurry up."

Behind Li Zheng, Xiao Jun reached out and patted his shoulder.

Li Zheng took a deep breath, stepped through the hatch, and entered the torpedo cabin.

Li Zheng was very familiar with the environment here.

He has trained many times on land and in the simulation cabin.

But there is one difference. There are only torpedo tubes in the simulation cabin, and there are no torpedoes.

And here's the real thing, just sitting on the shelf, ready for a quick reload and launch.

Thinking of the explosive power of this thing, Li Zheng couldn't help but take a few more glances.

The size of the torpedo tube is mostly three calibers in the world - 324mm, 533mm and 650mm (super heavy).

A 533 caliber torpedo tube lay in front of Li Zheng.

Xiao Jun took the initiative to stand on the side of the torpedo tube, first checked the diving equipment on Li Zheng's body, and then asked him: "Are you ready?!"

Li Zheng gave a thumbs up: "Ready!"

Xiao Jun didn't talk too much, and opened the gate of the launch tube together with the fish operator.

"Don't be afraid! Go in! Tap the pipe immediately if something happens! I'll get you out."

The inside of the torpedo tube was dark, and only a little reflection on the tube wall could be seen.

Li Zheng felt his mouth dry, but he still gritted his teeth, lowered his head, and got in.

When Li Zheng got halfway into his body, Xiao Jun and the operator pushed him in reasonably.

"Climb! Climb forward!"

Xiao Jun leaned in front of the nozzle and yelled into it.

Inside the torpedo tube, Li Zheng was lying on the cold tube wall.

Because it is in the sea, the steel on the pipe wall feels very cold.

It was still dark ahead, and the body could feel the narrowness of the torpedo tube, but the eyes could not see the end of the torpedo tube—the valve there was closed, and of course it was impossible to open it, otherwise the sea water would rush in.

Li Zheng began to crawl forward slowly.

He had a strange feeling that every time he climbed forward a little bit, even a little bit, he seemed to feel that there seemed to be a cliff in front of him, and if he climbed a little bit more, he would suddenly fall down and die forever.

The psychological pressure is increasing.

Li Zheng felt that his breathing was a little difficult.

For a moment, the thought of giving up flashed through my mind like a shooting star.

"Can not give up!"

He admonished himself silently in his heart.

We've come here, there's no turning back.

Die, also die in this pipe!
After that kind of vigor came up, Li Zheng gritted his teeth and climbed forward about two meters.

Then he heard movement behind him, and someone followed him into the pipe.

It must be his old squad leader, Hou Jun.

At this time, a warm current suddenly appeared in his heart.

No matter where he is, Hou Jun is a trustworthy comrade in arms, and he is worthy of handing over his back to his old squad leader.

The movement behind finally stopped.

Li Zheng knew that Hou Jun must have entered the pipe.

Then there was a bang, and the gate of the entrance closed.

At first there was a little light coming in from the torpedo cabin, but now there is no light at all.

Totally black.

The kind of black that can't be seen.

Suddenly, Li Zheng heard the familiar sound of water.

That's right.

It is exactly the same as when practicing in the simulation cabin. After entering, the gate is closed, and then the water is injected.

One of the most important procedures for climbing pipes during water injection.

Many soldiers often choose to knock on the wall of the tube to give up training because they can't bear the feeling of being gradually "overwhelmed" and the pressure on their body suddenly increases.

The water is cold.

This is serious sea water.

Li Zheng felt the water slowly submerging his body.

First a third, then a half, and finally the whole...

The oxygen mask began to supply air, but the body gradually began to feel it, because after the water was full, the pressure began to increase.

Now it has to be pressurized to the same pressure as the depth of 30 meters outside before the front gate will open, and then it is possible to climb out of the pipe and enter the sea.

Although this process took less than 10 minutes, it seemed as long as two years.

The training of climbing pipes is dangerous. Ordinary submariners climb pipes just to escape, while members of special forces have to carry equipment and equipment to climb pipes, and wear different diving suits. It is more dangerous than ordinary sailors. is much higher.

This is a dangerous subject. Once an accident occurs, the lightest is perforated eardrums, and the most serious is internal bleeding and suffocation to death...

In order to dispel his desire to work hard, Xiao Jun once said that someone died in an accident on this subject.

Li Zheng could hear his own heartbeat.

There is also the sound of heavy and somewhat rapid breathing.

He stretched out his hand and grasped firmly on the pipe wall.

His fingers were trembling slightly.

Several times, he almost wanted to knock on the wall of the pipe.

The surrounding cold tube walls seem to be slowly squeezing towards the middle, trying to squeeze themselves into meat sauce.

This caused him some shortness of breath.

Typical claustrophobic response.

Fortunately, it's slight, at least he hasn't collapsed until now.

At first, Li Zheng was still counting the time in his mind.

Because the time is up, the front hatch will open after the pressurization is completed, as long as I climb out, everything will be successful!
But I don't know when it started, he has forgotten to count the time silently.

I chanted a sentence over and over again in my mind, trying to keep my mind clear.

"Hold on, hold on!"

He felt that his head was starting to swell, and it seemed that he had reached a critical point. His hands that were pinned to the wall of the tube were shaking more and more. Although the temperature here was extremely low, Li Zheng felt that he was sweating all over and had a fever...

Not long after, buzzing sounds appeared in his ears, and all he heard were noises, instead of the deathly silence.

This is simply a kind of torture, a kind of torment.

Finally, he felt that he couldn't bear it anymore, because he couldn't breathe any more oxygen.

I don't know if there is a problem with the diving equipment, or if there is a problem with the oxygen device...

Hou Jun, who was lying behind him, suddenly felt that Li Zheng in front struggled violently.

He was startled.

Did something happen?
collapsed?
He immediately raised his hand, wanting to hit the pipe wall.

　Ask for a monthly pass, ask for a monthly pass!
