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

Now it needs to be pressurized to the same pressure as the depth of 30 meters outside, then the front gate will open, and then you can climb out of the pipe and enter the sea.

Although this process only lasted less than twenty minutes, it felt like two years.

The training of climbing a pipe is dangerous. Ordinary submariners climb the pipe just to escape, while members of the special forces must carry equipment and equipment when climbing the pipe, and they wear different diving suits, which is more dangerous than ordinary sailors.

is much higher.

This is a dangerous subject. Once an accident occurs, it can range from eardrum perforation to death from internal bleeding and suffocation...

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

Li Zheng could hear his own heartbeat.

There was also heavy and somewhat rapid breathing.

He stretched out his hand and grabbed hard on the wall of the pipe.

The fingers are trembling slightly.

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

The surrounding cold tube walls seemed to be slowly squeezing toward the center, squeezing themselves into pulp.

This caused him to have difficulty breathing.

Typical claustrophobic reaction.

Fortunately, it's minor, at least he hasn't collapsed yet.

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

Because when the time is up, the front hatch will open after the pressurization is completed. As long as you climb out, everything will be a success!

But he doesn't know since when, he has forgotten to count the time silently.

I muttered one sentence over and over again in my mind, trying to keep my mind clear.

"Hold on, hold on!"

He felt that his head was beginning to swell, and it seemed to have reached a critical point. The hands on the wall of the tube were shaking more and more violently. Although the temperature here was extremely low, Li Zheng actually felt that he was sweating and feverish...

Soon after, there was a buzzing sound in his ears, and all he heard was noise, instead of the deathly silence.

This is simply a kind of torture and suffering.

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 something wrong with the diving device or the oxygen device...

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

He was suddenly startled.

Did something happen?

collapsed?

He immediately raised his hand and wanted to knock on the wall of the pipe.
Chapter completed!
