Lieutenant Gallon was a powerful figure on the football field and was an idol in the minds of everyone in the Navy, but once he entered the water, he was far from it.

Lieutenant Gallong's training results in C-platoon have always been unsatisfactory.

He is one of the most diligent in the class, but his training results are far from proportional to the hardships he has put in.

When you are almost thirty, your physical fitness is naturally not as good as other young men at work.

When the age is 25, if the body function is as natural as the ballistics of a bullet, it reaches its highest point, and then it will decline.

That's what Lieutenant Gallon was like.

He came here for his ideals and family honors. When others dropped out of school, he gritted his teeth and persevered. However, the conditions were limited, and his grades were not very good.

The most unlucky one is his once glorious center forward in the Navy football team. He is a little famous and acquainted with the instructors in the team.

According to the strange rules of the sas training team, he was the one who was punished the most.

This time he was in the end.

When he found the marker and was about to float, other teammates around had already been on the water.

As Gallon's partner, although the two of them did not conduct cooperative training in this subject, they went to the water and handed over the markers. Zhuangyan suddenly noticed that there was no Lieutenant Gallon in the heads on the water.

"Did you see Garon just now?"

Zhuangyan still asked Kasim, who was right next to him.

Qasim shook his head and said, "I didn't see it. I took the mark and floated up. I didn't notice him."

The sea water swayed restlessly, floating solemnly on the water surface, and vaguely felt something was wrong.

He wanted to dive again and look for Lieutenant Gallon.

But thinking that there are three instructors at the bottom of the sea, it should be fine.

After counting other teammates on the sea, a total of 17 people came back, which means that only Garon has not returned yet.

He was still worried, so he took a breath and planned to go into the water to take a look.

Unexpectedly, as soon as I lowered my head, I saw Garon rushing up from the sea like a flying fish and floated directly to the water.

“Huhuhuhu——”

As soon as he reached the water, Garron opened his mouth and breathed wildly like drowning.

Because the mask covered his nostrils and eyes, he felt that he was not breathing happily enough, so he took off his mask.

"Are you okay? Gallon!" Zhuang Yan swam to him and held his armpit with one hand.

This guy looks really scary. His mouth is like a big mouth of a catfish, and you can see the uvula on the soft palate in his mouth.

"It's okay...it's okay..."

It took Garon a while to recover.

Swimming to the rubber boat, handing over the mark, then climbing onto the boat, and lying directly on the floor.

Zhuangyan also got on the boat and suddenly noticed that Gallon's eyes had turned blood red.

"Galon! There's something wrong with your eyes!"

"Is it... yes?" Garron swallowed, he couldn't see his eyes, so he asked Zhuang Yan nervously: "What's wrong with my eyes?"

Free diving may also cause symptoms of decompression.

He went over solemnly, squatted beside him, stretching out his eyelids.

Gallon's first pair of eyes should have red eyes, and the situation was like having red eyes when he was a child, or wearing red contact lenses.

"Instructor Ahmed!"

If Zhuang Yan feels it, report it quickly.

Because there are military doctors accompanying the team on the dock not far away. If it is decompression, you can do some treatment immediately.

The light dive depth of 35 meters is not high, so there will be no serious consequences.

Ahmed also noticed what was happening behind him.

When he came over and saw that, he didn't care about waiting for others, shouted to the students on a rubber boat next door: "When your instructor comes back, you can go back to the dock yourself, I have to rush back!"

The students on the rubber boat opposite could probably guess what happened. They all looked serious and nodded suddenly, stretching their necks and looking at Garon's position.

xx bless you!

When I arrived at the shore, I boarded the dock, and the military doctor rushed over.

After some examination, the military doctor breathed a sigh of relief and said to Garon who was lying on the ground: "Lieutenant, you are lucky. If you pulled your mirror a little earlier, your eyes would explode."

Then he said to Ahmed: "It's okay, take a break and don't let him participate in the next diving training. Go to the medical car to rest for a while, and I will give him some treatment."

Gallon was fine, and Zhuangyan breathed a sigh of relief.

Fortunately, it is not a serious symptom of decompression.

In fact, when it comes to stress relief, you can’t help but worry about your partner.

Light diving is better. If it is scuba diving in depth, then the pressure relief time of different depths in the water must be calculated.

Theoretically, when the breathing gases are the same and the depth is the same, the longer the diving time, the greater the risk of decompression disease. Therefore, in order to prevent decompression disease, divers sometimes need to perform phased decompression stays underwater so that their bodies can discharge enough nitrogen.

The time to relieve pressure is actually a critical time calculated. After years of research and experiments, scientists have come up with a set of theories and formulas. Through many factors such as the depth, duration, number of repeated dives, the nitrogen-oxygen ratio of the breathed gas, and the water surface residence time, the nitrogen-content level in your body. Then, based on this level, calculate the time you can stay at a certain depth when your next dive is longer than this time, you must perform the phased underwater pressure decompression (decompression dive) mentioned above, otherwise you will have a great risk of disease.

If this time does not exceed this time, for example, for general recreational diving, divers usually only need to control the upgrade speed and, at the end, simply do a five-meter three-point stay (no pressure-reducing diving).

However, long-term and high-deep underwater operations like military diving must be strictly controlled and calculated.

Once calculation errors occur, things often happen.

only……

Zhuangyan has seen the calculation ability of students from T country.

After joining the team, I performed a quick calculation in the school swimming pool, but there were 36 students in the entire C platoon, of which 24 were officers and soldiers of the T-Second Army.

24 people actually calculated 24 different answers...

The three Chinese officers and soldiers only calculated one answer, and the one that was the correct one.

Before coming to T country, Zhuang Yan heard a saying that if there is anything that can crush T square in learning, one thing is absolutely possible, that is, subjects involving fast mental arithmetic.

Because those people don't even know how to multiply table...

Now, Lieutenant Gallon is about to rest.

Zhuangyan has to face a problem - who will he partner with for the next deep dive?

"Instructor Ahmed."

He had to ask the chief instructor Ahmed.

"Lt. Gallon is injured. Who will I be with later?"
