He is two meters and five centimeters tall. Who made him a soldier?

Chapter 283 Broken Oxygen Tank
The instructor in charge of this subject couldn't help but speak to the veteran next to him who was also wearing a diving suit.

They only carried enough oxygen for twenty minutes. If they didn't come up within nineteen minutes, the students below would definitely be in danger. They couldn't take the risk of this possibility.

"clear."

The veteran security guard beside him nodded.

Lu Qinglong looked anxiously at the sea surface, which was occasionally choppy. He couldn't see clearly what the situation was like under the water.

What if Ji Baichang got lost down there? What if he didn't find the target and was diverted to other sea areas?
Or what if the person down there faints from claustrophobia? What should we do then?
For a moment, all kinds of random thoughts filled Lu Qinglong's mind, making him a little flustered.

"Eighteen minutes, and there is only one minute left."

"If he hasn't come up in the last minute, go down and fish him out."

The instructor looked at the stopwatch in his hand and the sea level which showed no signs of rising.

This is the last test for this subject. If Ji Baichang is still missing after nineteen minutes, then no matter whether he can complete the test or not, they will definitely bring Ji Baichang up.

At worst, we can just rebuild the relationship, but we can't let him get hurt.

Time passed by minute by minute, and nineteen minutes soon arrived. Seeing that Ji Baichang was still in the sea and had not come up yet, the instructor immediately signaled to the safety officer to go down and rescue Ji Baichang.

This also means that Ji Baichang's assessment has failed.

Military academies will adopt the same retaking mechanism as local universities for students who fail the assessment in minor subjects.

That is to say, you will find an opportunity to take another round of assessment. If you still fail after retaking the exam, then this subject will be marked as unsatisfactory on your resume when you graduate.

It doesn’t mean that if you fail to complete this subject, you will be demoted to your original unit and will not be able to graduate from the military academy.

But this unsatisfactory record in underwater combat will accompany him for the rest of his life.

After graduation, when you go to various units, company supervisors and battalion commanders will look at your resume and mark the item "Unqualified for underwater combat" in red, making it particularly eye-catching.

All in all, this is a very shameful thing.

Before graduation, all members of the military academy will retake the subjects in which they failed previously until they pass.

"Wait a minute, don't get in the water yet!"

Just as the safety officer was preparing to go into the water to fish out Ji Baichang from the bottom, the sharp-eyed Lu Qinglong saw a dark shadow rapidly rising from the bottom of the turbid sea water.

Everyone was stunned for a moment, then they all looked in the direction of Lu Qinglong's sight, and indeed they saw a figure floating up.

At this time, the teacher also stared at his stopwatch and counted silently:
"Fifteen seconds."

"Fourteen seconds."

"Thirteen seconds."

Ji Baichang's figure suddenly broke out of sleep, tore off the mask on his face and shouted:
"Report, mission accomplished!"

The instructor also pressed the pause button on the stopwatch at the same time Ji Baichang shouted "Report".

In the end, Ji Baichang's time stayed at nineteen minutes and fifty-three seconds.

“Just barely passed.”

"Okay, come up and let's take over."

The teacher breathed a sigh of relief.

In fact, he has always liked the student Ji Baichang.

It's not just that Ji Baichang is good at talking, but he's also good at handling things.

The main reason was that he really saw Ji Baichang’s efforts.

Despite suffering from claustrophobia, he still managed to practice the relevant exercises in the limited time every day. In addition to normal training time, he also took out most of his rest time to do the relevant exercises.

At the beginning, I fainted when I dived from the initial diving depth of twelve meters. After practicing slowly, I have now reached a full thirty meters.

In fact, for students like them who suffer from claustrophobia, most of them simply cannot dive to a depth of 20 meters alone in this underwater operation subject.

Ji Baichang’s words were already considered a breakthrough.

After being pulled up by the instructor and the safety officer, Ji Baichang's face turned pale and he could hardly stand. In the end, he forced himself to sit on the speedboat.

"That was pretty good. I found the direction and completed the shooting mission all by myself at a depth of 30 meters underwater."

"That's pretty good. Even though it took you a little longer than others, you're doing fine."

The teacher patted Ji Baichang on the shoulder and encouraged him.

Ji Baichang endured the dizziness in his head and nodded in response.

The instructor probably saw that Ji Baichang was not in a good condition and needed to take a break, so he did not continue talking to Ji Baichang, but looked at the next person, Lu Qinglong, and asked him to make final preparations.

"are you ready?"

"Instructor, I'm ready to start."

Lu Qinglong nodded seriously to the instructor and then put on his oxygen mask.

After the instructor gave him a thumbs up, Lu Qinglong quickly dived into the water.

After he left the speedboat, the entire speedboat suddenly tilted towards the side where there were more people. Fortunately, two veterans sat over there and the speedboat, which was about to capsize, regained its stability.

That is, at the same time when Lu Qinglong left the speedboat, the instructor pressed the timing button.

After entering the sea, Lu Qinglong immediately sank to a depth of 30 meters at an extremely fast speed.

If it were other students, when they reached a water depth of 30 meters, they would have been able to feel very obvious pressure.

That is, they were wearing diving suits. If they were not wearing diving suits, their eardrums would not be able to withstand the pressure and would rupture.

But there was no adverse reaction to Lu Qinglong's words.

The location here should have been carefully selected by the military academy instructors. The deepest place is only about 35 meters deep, and there are no deep-sea pits or anything like that.

So Lu Qinglong simply didn't control his body weight and floated up, and his whole feet stepped firmly on the ground on the seabed.

The whole person walked as if on flat ground, and then looked at the compass in his hand, and walked towards the target in the southeast direction at a not slow speed.

The speed at which he walks on the seabed is almost much faster than that of others swimming on the seabed.

After all, the weight is there, and Lu Qinglong rarely takes advantage of the weight that brings him.

However, after walking nearly three hundred meters in the southeast direction, Lu Qinglong discovered a very serious problem.

That was the amount of oxygen he had consumed in his oxygen tank, which was already more than half full.

You have to know that the oxygen content in the oxygen cylinders carried by everyone who came down for the assessment was the same.

The oxygen level is dropping so fast, which means that the oxygen bottle that Lu Qinglong is carrying is damaged, which is why the oxygen is dropping so fast. "Confirm that there is no problem with the direction I am heading. There are still about 200 meters to the target."

"After reaching the target, there may not be much oxygen left."

After Lu Qinglong briefly analyzed the current situation, he immediately chose to move forward.

Maybe there was something wrong with the original oxygen tank, and I was diving too deep?
"Thirty-five meters is still deep? I used to dive to sixty meters without any problem."

Lu Qinglong simply muttered something in his heart and continued walking forward.

After walking forward for about two minutes, I successfully saw the target in front of me that I needed to hit.

It was a human-shaped target, on which had been inserted colorful bullets from a special underwater rifle.

Each person is equipped with a different color of bullets. After everyone in a class has finished shooting, the target is fished up and the colors of the bullets on the target can be used to distinguish whether all of them have hit the target.

The target was set at a depth of about thirty meters, which was just the right depth in the water.

Lu Qinglong walked forward, fired, and watched his bullet with a red tail hit the target, then turned around and walked back.

It was also at this time that Lu Qinglong lowered his head and checked his gas tank again.

I saw that the oxygen content in the gas cylinder had reached the bottom.

It had already taken me five minutes just to get here.

This means that Lu Qinglong has only two choices. One is to surface immediately and then explain the situation to the instructor.

And tell the instructor that your gas cylinder is damaged.

I believe the teacher will not make things difficult for me by arranging a make-up exam for me.

As for the second situation, Lu Qinglong would endure the situation of being unable to breathe for five minutes, walk 500 meters back to the original place, and then float up again.

During this period, you also need to walk for five minutes, and every step you take will drain the oxygen from your lungs to a certain extent.

If it were someone else, they would have floated up long ago.

But Lu Qinglong was different. He chose the second option, which was to go back the same way he came.

Lu Qinglong first took off his oxygen mask and exhaled the last breath of carbon dioxide.

Then he put on the oxygen mask again and took a deep breath of the oxygen in the bottle until the pointer on the instrument moved to the far right, indicating no oxygen, and then stopped.

Taking off the oxygen mask, Lu Qinglong kept himself at a depth of 30 meters and began to swim back.

At this time on the sea level, Ji Baichang had recovered a little while sitting on the speedboat. He sat next to Xue Daochao and took the same action as Xue Daochao, lying on the edge of the speedboat and looking underwater.

"Old Xue, what do you think Qinglong will take?"

"I remember that he seems to be the best swimmer among the three of us. He should be pretty fast."

"Twelve minutes? Maybe even eleven."

Ji Baichang asked casually with a relaxed look on his face.

I am very confident about Lu Qinglong and the others.

Lu Qinglong is neither directionally challenged nor claustrophobic.

Moreover, he had said before that he had no problem diving to a depth of 60 meters without any instruments or equipment, which made them feel it was exaggerated.

You have to know that when they are wearing equipment, diving to a depth of 30 meters is really the limit of their physical strength. Swimming forward at a depth of 30 meters, it feels like the whole body is pressed by a heavy object, which is very, very strenuous.

Not to mention not carrying any equipment.

Ji Baichang and Xue Daochao had tried it before. Without wearing any equipment, they dived to a depth of 15 meters, but their bodies could not bear it.

God knows what kind of monster's physique Lu Qinglong has to be to be able to dive sixty meters without any equipment.

"Almost eleven minutes."

"Qinglong should be much faster than me."

Xue Daochao's idea was basically the same as Ji Baichang's, both of them had great trust in Lu Qinglong.

After all, Lu Qinglong's physical fitness is so strong, and he is much better than the two of them in every aspect. There is no need for them to worry about Lu Qinglong at all, because Lu Qinglong can do well on his own.

"Indeed, if it's Qinglong, then we don't need to worry, right?"

"Hey! A dark shadow is coming up! Lu Qinglong is coming up!"

Ji Baichang looked at Lu Qinglong rising from the sea at a very fast speed and immediately shouted.

The instructor at the side also quickly grabbed his stopwatch and looked at the time on it.

It's been just over ten minutes.

"puff!"

Lu Qinglong suddenly leaned out from the sea level, his face seemed a little pale, but he looked no different than usual.

As soon as he reached the sea level, he took two deep breaths of air, and the color of his face regained its rosy color at a speed visible to the naked eye.

After Lu Qinglong boarded the speedboat, the instructor immediately discovered that Lu Qinglong had inserted the oxygen mask back into the mouth of the gas cylinder.

This action couldn't possibly be done after getting ashore, right?

How did Lu Qinglong manage to put his oxygen mask back under the water and then swim out?

Teacher You was puzzled and immediately asked Lu Qinglong in confusion:
"Lu Qinglong, why is your oxygen mask stuck on the bottle?"

Listening to the teacher's words, Lu Qinglong turned around and replied cheerfully with a smile on his face:

"Instructor, among this batch of gas cylinders, the one assigned to me has some cracks. It can't withstand the pressure, and the oxygen has diffused."

"After I finished shooting, the oxygen in here was empty, so I plugged it back in."

Lu Qinglong answered with a relaxed look on his face.

Judging from his expression, it seemed like he was talking about a trivial matter.

But after hearing what Lu Qinglong said, the teacher's face showed a look of surprise.

With a slightly trembling voice, he continued:

"So what you mean is that you are in a state without any oxygen."

"From 500 meters away from the starting point, swim to the starting point, and then float up 30 meters, right?"

The teacher's voice was filled with confusion, doubt and puzzlement.

He didn't understand how he managed to swim back 500 meters without oxygen, especially in a water depth of 30 meters.
Is this still a human being? !
