Lieutenant Garon is imposing on the football field and is an idol in the eyes of everyone in the Navy, but once in the water, it is far from it.

All the while, Lieutenant Garon's training performance in Platoon C has been unsatisfactory.

He is one of the hardest working people in the class, but the training performance and the hard work are far from proportional.

People are approaching 30, and their physical fitness is naturally better than other young men who are not at work.

When you are 25 years old, your body functions according to the laws of nature, just like the ballistic trajectory of a bullet. When it reaches the highest point, it will slide down.

Lieutenant Garon is like that.

He came here for his ideals, for the honor of his family, and when others dropped out, he gritted his teeth and persevered, but the conditions were limited and his grades were not very good.

The most unfortunate thing is his status as the center of the once brilliant Navy football team.

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

This time, he landed at the end again.

By the time he found the marker and was about to float up, the other teammates around him were already on the water.

As Jialong's partner, although the two of them did not have cooperative training in this subject, but after getting on the water and handing in the marker, Zhuang Yan suddenly noticed that there was no Lieutenant Jialong among the people on the water.

"Did you see Garen just now?"

Zhuang Yan still asked Kasim, who was next to him, in a heartless way.

Kasim shook his head and said, "I didn't see it. I took the marker and floated up without noticing him."

The sea swayed restlessly, floating solemnly on the water, vaguely feeling that something was wrong.

He wanted to dive again and find Lieutenant Garon.

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

After counting the other teammates on the sea, a total of 17 people came back, that is to say, only Jialong has not returned.

Still worried, he took a breath and planned to go into the water to see.

Unexpectedly, as soon as he lowered his head, he saw Garen rushing up from the bottom of the sea like a flying fish and surfaced directly.

"Whoohoo-"

As soon as he reached the surface of the water, Garen opened his mouth and breathed frantically as if he wanted to drown.

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

"Are you alright! Jialong!" Zhuang Yan swam to his side and held his armpit with one hand.

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

"it's okay no problem…"

It took a while for Garen to recover.

Swim to the rubber boat, hand in the marker, then climbed onto the boat and lay directly on the floor.

Zhuang Yan also got on the boat, and suddenly noticed that Garen's eyes had turned blood red.

"Canon! Something's wrong with your eyes!"

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

Decompression symptoms may also occur during freediving.

He went over solemnly, squatted beside him, and opened his eyelids.

Garen's first pair of eyes should have been completely red in the whites of the eyes. It was like having pink eye when he was a child, or wearing red contact lenses or something.

"Instructor Ahmed!"

Solemn felt that he hurried to report.

Because there is a military doctor accompanying the team on the pier not far away, if it is decompression sickness, it can be dealt with immediately.

The light diving depth of 35 meters is not high, and it stands to reason that there will be no serious consequences.

Ahmed also noticed what was happening behind him.

He came over to take a look, but he couldn't wait for others, and shouted to the students on a rubber boat next door: "When your instructors come back, you can go back to the dock yourself, I have to go back!"

The students on the opposite rubber boat could probably guess what was going on. They all had serious faces, nodded sharply, and kept stretching their necks to look at Garen's position.

xx bless!

Came to the shore, boarded the pier, and the military doctor rushed over.

After some inspections, the military doctor breathed a sigh of relief and said to Garen lying on the ground: "Lieutenant, you are lucky, if you tear off your mask earlier, I'm afraid your eyeballs will explode. opened."

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

Jia Long was fine, and Zhuang Yan was relieved.

Fortunately, it is not a serious decompression symptom.

In fact, regarding decompression sickness, I can't help but solemnly not worry about my partner.

Scuba diving is even better, if it is a deep scuba dive, it is necessary to calculate the no-decompression time at different depths in the water.

In theory, under the condition of the same breathing gas and the same depth, the longer the dive time, the greater the risk of decompression sickness. Therefore, in order to prevent decompression sickness, divers sometimes need to perform phased underwater Decompression stops allow your body to excrete enough nitrogen.

The no-decompression time is actually a calculated critical time. After years of research and experiments, scientists have come up with a set of theories and formulas, which are derived from many factors such as the depth of the previous dive, the length of the dive, the number of repeated dives, the nitrogen-to-oxygen ratio of the gas breathed, and the time spent on the surface. The nitrogen content level in your body, and then according to this level, calculate the time you can stay at a certain depth in the next dive. If the time exceeds this time, you must carry out the above-mentioned underwater stage decompression (decompression). diving), otherwise there is a great risk of illness.

If this time is not exceeded, such as for general recreational diving, the diver generally only needs to control the ascent speed, and at the end, simply do a three-minute stop of five meters (no-decompression diving).

However, for long-term, high-depth underwater operations like military diving, the no-decompression time must be strictly controlled and calculated.

Miscalculations often lead to accidents.

only…

Zhuang Yan has seen the computing ability of students in country t.

After joining the team, I did a quick calculation in the school swimming pool, but there are still 36 students in the entire C platoon, of which 24 are officers and soldiers of the T army. UU Reading www.uukanshu.com

24 people, actually calculated 24 different answers...

The three Chinese officers and soldiers only figured out one answer, and it was the most correct one.

Before coming to T country, Zhuang Yan had heard a saying that if there is anything that can crush T square in learning, there is one thing that can definitely be done, and that is subjects involving rapid mental arithmetic.

Because those people don't even know the nine-nine multiplication table...

Now, Lieutenant Garon is going to rest.

Zhuang Yan had to face a question - who will he partner with in the next deep dive?

"Instructor Ahmed."

He had to ask the bishop Ahmed.

"Lieutenant Garon is injured, who am I going to be with?"

Ahmed thought for a while and said, "Come with me!"
