Song Yuanzheng served in the army as a professional engineering diver and had very rich underwater experience.

The area searched by the second team was to the left of the first team led by captain Li Wenming.

Song Yuanzheng took another coach to the bottom of the sea just dived, the coach was a little confused because of some nitrogen anesthesia, the counterweight on the trainer had been increased to the maximum, and the professional anti-pressure suit was very tight, as soon as he arrived at the bottom of the sea, the professional diving action was a little deformed, like being drunk.

I just grabbed my harpoon and was ready to go to the bottom of the sea.

Leaning forward, the flippers on the feet instinctively paddled downward, so that the mud and sand on the bottom of the sea were rolled up, and the instructor's diving goggles were suddenly cloudy, and nothing could be seen.

People are like this, in a closed, nervous, high-pressure and somewhat confused situation, once they are suddenly entangled in something, they will instinctively react to stress.

The more nervous a person is, the more likely they are to make mistakes.

The more the coach kicked the fishing net, the tighter it was entangled, and it was too late to turn around and want to cut the fishing net with a diving blade, the whole fishing net wrapped the body, the coach was completely panicked, desperately struggling, at this time, the more struggling people became, the more panicked they were, and when they panicked, their breathing accelerated, and the amount of inhalation increased greatly, and the more obvious the situation of nitrogen anesthesia.

The instructor was in a hurry and in a trance, and his body struggled wildly, stirring up the entire seabed with rolled up mud and sand, and he couldn't see anything at all.

Only a powerful diving lamp can still emit a faint light.

At this time, Song Yuanzheng also found out that the coach had an accident, so he quickly swam over and made gestures to calm the coach and not panic.

Song Yuanzheng unhurriedly cut the fishing net with a diving blade, and the coach also quieted down at this time, motionless to cooperate with Song Yuanzheng's movements.

Saving people is a race against time, and Song Yuanzheng also pulled the safety rope in accordance with the diving rules before rescuing people, so as to tell the platform that he was in distress underwater.

Haozai and Wan'er, who had been waiting anxiously, always paid attention to the movement of the safety rope, saw that they were in distress underwater, and hurriedly put on their equipment and made preparations before entering the water.

In the first team, only the captain Li Wenming can still dive, but he needs to rest and let his body relax, after all, it is a 120-meter non-saturated deep dive. People should slowly do stress tolerance restoration. Otherwise, there is a lot of harm to the body.

Looking at the current situation, there was no choice but for them to dive down in reserve to save people.

I don't know what danger is underwater, after the analysis and deployment of the captain.

This time, Guan Hao dived alone to save people.

The second team has been diving for more than 30 minutes.

Under normal circumstances, the S80 oxygen cylinder can supply gas for 40 minutes, but the gas consumption will increase when there is a dangerous situation.

Guan Hao brought a spare gas cylinder and dived quickly to save people.

Follow the anchor chain down to the bottom of the sea at a depth of more than 120 meters, almost nothing can be seen, Guan Hao pulled the second team of safety ropes step by step, from the platform to the bottom of the sea Guan Hao took a total of 4 and a half minutes, more than 60 meters to start, in order to avoid nitrogen anesthesia, as much as possible to reduce the number of breaths, at this time the natural BTV ear pressure balance breathing advantage is very obvious.

Through the BTV method, Guan Hao easily avoided the discomfort of ear pressure caused by deep diving, and at the same time inhaled much less nitrogen and oxygen synthesis gas than usual by means similar to fish breathing, so that he did not have nitrogen anesthesia at all, so he easily dived to the bottom of the sea.

Guan Hao slowly groped around the turbid seabed according to the area that the second team wanted to search, and finally saw the faint light of the diving flashlight, there was no doubt that it was the second team in distress.

After a quick swim approaching, Guan Hao had a brief exchange with Song Yuanzheng who was saving people in underwater sign language, and learned that the oxygen consumption of the second team was very large, and the diving time was running out.

Guan Hao didn't have time to think about it and quickly joined the ranks of saving people.

At this time, the coach was not very conscious, in a semi-comatose state, and must be sent to the platform for treatment immediately.

Song Yuanzheng's gas cylinders were also about to run out.

The two of them accelerated the speed of cutting and breaking the net, and at this time, there was one more person not only to speed up the pace of rescue, but also to the psychological comfort of the rescued, and the progress was obviously accelerated a lot.

Just when Song Yuanzheng's gas cylinder was about to run out, the two helped the coach successfully cut the broken net, Guan Hao gave Song Yuanzheng the spare gas cylinder he brought, and the coach had lost his ability to move, so Song Yuanzheng could only take him to the platform for treatment.

Guan Hao decided to stay alone to continue exploring the salvage, so he briefly communicated his thoughts with Song Yuanzheng and bid farewell to the second group.

Guan Hao began to search for salvage objects alone.

The search area of the second team has been completed in Guan Hao's careful search, and there is no trace of the salvaged objects.

So Guan Hao swam to the first team's search area, Guan Hao has long been familiar with the underwater environment and pressure, has extraordinary breath-holding ability and BTV breathing blessing, his oxygen consumption on the seabed is much lower than ordinary people, a bottle of nitrogen oxygen synthetic air, he can stay in the water for more than 50 minutes, and nitrogen anesthesia basically does not appear.

No wonder the instructors say he was born to dive.

It has been 42 minutes since the water was launched, and Guan Hao is still searching for the iron guy.

Guan Hao holds a harpoon tied to a magnet in one hand and water and electricity in the other, and relies on the flippers of his feet to propel and control his balance.

The sediment accumulation on the seabed is too thick, and the search factor is very difficult, and it is necessary to search very carefully to find the target.

After another 3 minutes, only a small piece of the first team's search area remained, and the 2-ton iron guy was still nowhere to be seen.

At this time, there is not much oxygen left, and if you count the amount of oxygen used to float to the platform, you can last underwater for a maximum of 15 minutes.

At a depth of 125 meters, the nitrogen oxygen synthetic air tank has a diving time of 60 minutes, which is definitely a new record in China.

Guan Hao continued to search, and just when the oxygen reached the warning signal, the harpoon in the water was poking downward, and it was obvious that something hard was pushing against it.

In order to verify that the metal is below, Guan Hao used force to see if the magnet on the harpoon was sucked up, and sure enough, the harpoon belt did not move, and the strong magnet was firmly sucked, confirming that there was metal under the sediment.

Great, Huang Tian paid off, and after the unremitting efforts of many people, he finally found the salvage.

Guan Hao was excited for a moment, and the person immediately cheered up for twelve points, at this time he didn't dare to be sloppy, swam over, went to the metal and picked up a thick layer of mud and sand on the metal with his hands, the visibility was zero, and he couldn't observe it but rely on the mold, Guan Hao groped carefully, he wanted to make sure it was salvage.

It took Guan Hao five minutes to swim around the perimeter of the metal, and he carefully molded it with his hands, and he could determine the stabilization system on the oil rig to be salvaged.

There was not much oxygen left in the oxygen cylinder, Guan Hao marked it with a small flag, and at the same time, for the sake of insurance, he tied a safety rope with his own harpoon to fix it on the salvage, and did everything well, and the oxygen was completely exhausted.

Without oxygen, Guan Hao knew that he could only rely on his own breathing to complete the 125-meter ascent, which was really a tough battle!

It's going to be a serious challenge.

According to the content of the diving rules, Guan Hao will lose a part of his weight every 30 meters of floating, and try to control the speed of the float to reduce the pressure on his body.

On the road of more than 120 meters, Guan Hao spent 6 points, which means that he held his breath and created a new Chinese record.

When Guan Hao floated up from the water and came out of the water, everyone looked at the magical boy silently with that expectant and excited look, followed by thunderous applause.

It took a long time for everyone to stop applauding in Cao Wan's concerned voice.

"Okay, are you alright? How are you feeling right now? Where is there any discomfort? ”

"Fool, you're scared me to death! Do you know? You've broken the record for 72 minutes of diving. ”

"I'm fine, don't worry! How's the vice-captain and coaches doing? Is it dangerous? ”

"The vice-captain has nothing to do, just take a simple break to adapt to the pressure, but the coach's situation is worse, the nitrogen anesthesia is heavier, and now the person is in a coma, the commander has contacted the land, and when the rain stops, he will arrange a speedboat to be sent to the hospital for treatment, and now he can only have a platform for medical staff to do some simple care, and he can only resign himself to fate."

"Hey, the underwater conditions are so bad that the instructor was in danger after he got entangled in a fishing net."

"It's good for you to come back, now you can rest first, and we'll talk in detail later."

.......

It is true that he has to rest for a while, to get used to the atmospheric pressure, and after a while, he will recover.

Now the whole room was watching him quietly, not daring to disturb him in the slightest.

Even if all are very curious about what is going on underwater.

The Commander and Pete were also in the house.

Guan Hao lay quietly on the marching bed, and after about 20 minutes, he was almost recovered.

Guan Hao stood up and said to the commander, "Commander, the salvage has been found!" ”
