Chapter 593 Crossing the "Deep Pool"

failure?

Lin Yuan: (1`1;)
It seems that the speed was too fast and it was considered a failure.

Before he could speak, Henry asked, "Lin Yuan, where did you get the yellow oxygen cylinder?"

Old Peter was also stunned when he heard Henry's words.

The oxygen cylinders transported by the rescue team are all orange-red.

He watched Lin Yuan go into the water carrying two orange-red oxygen cylinders, but when he came back, why did one of them turn yellow?

Lin Yuan said: "We changed an oxygen cylinder at the old Camp 5. I found nearly 100 oxygen cylinders there, which can greatly speed up the rescue process."

"Wait, what did you say? You arrived at Camp 5?" Henry said in disbelief.

"That's not right. You were only in the water for 63 minutes. How could you possibly go back and forth to Camp 5?" Old Peter asked doubtfully.

"I'm a good swimmer and can swim faster," said Lin Yuan.

Can this be explained by swimming faster?
Old Peter held his forehead and sat down. "Let me sort out my thoughts. They're a bit confused right now."

"You reached Camp 5, but there's a long underwater section leading to Camp 5 without a guide rope. So you laid a guide rope to Camp 5 in such a short time?"

"Well, the guide rope has not only been laid to Camp No. 5, but also connected to the deep pool. The entire line is now connected." Lin Yuan said.

"God! Did I hear it wrong?" Old Peter jumped up from the ground in surprise.

Henry was also surprised and said, "You paved such a long passage in one go? How did you do it?"

They were all very familiar with the map of the underground passage and knew that this section was 5 to 60 meters long and would require at least 20 nails, which would definitely take a long time.

Old Peter knew that if he were to do this, the total round trip might take 5 hours or even more.

However, the round trip and the time spent by Lin Yuan, including the time for laying the guide rope, only took 63 minutes.

This completely overturned the situation of the four rescue team members. Does Lin Yuan have some magic?

Facing the doubts of several team members, Lin Yuan said: "It's nothing, I just swim faster and don't do any decompression. I rely on my physical fitness to endure it."

These words shocked everyone: How could they not relieve stress?

At this time, Lin Yuan was taking off his diving suit and changing into his cotton jacket. Although his body could withstand it, the wet and cold diving suit was very uncomfortable sticking to his body.

Old Peter, Henry and others stepped forward, looked around Lin Yuan carefully, and checked the skin exposed on his naked upper body.

"There were no rashes or bruises on the skin, and no symptoms of decompression sickness at all. It was incredible!" said Henry.

"I suddenly feel that I have been diving for nothing for the past 25 years. How can I still dive like this?" Old Peter said sourly.

The other two rescue team members also nodded frantically.

Lin Yuan's performance today completely broke all their expectations:
With water temperatures as cold as 4 degrees Celsius, divers should wear dry suits to keep warm and prevent hypothermia.

As a result, Lin Yuan went into the water directly wearing a wet diving suit and was not affected at all.

When diving to a depth of less than 10 meters, one has to worry about decompression sickness, but Lin Yuan dived to a depth of 35 meters underwater and quickly surfaced in one breath without any decompression.

What's even more outrageous is that he hasn't shown any symptoms of decompression sickness, which is simply a medical miracle.

In addition, they are all the best cave divers, so they will not ignore Lin Yuan's underwater swimming speed.

Even if we exclude the time spent on laying the guide rope, Lin Yuan's speed in swimming back and forth is quite amazing. It only took him about 30 minutes, while other excellent divers would need at least 2 hours.

This is not even a human being. They would not doubt that Lin Yuan is an aquatic creature.

Overall, Lin Yuan's performance is enough to support the cognitive framework they have built over the years.

If Lin Yuan had not brought back an oxygen cylinder from Camp No. 5, they would not have believed that Lin Yuan had done it.

"Give me something to eat. I'm a little hungry." Lin Yuan had already changed his clothes and walked to a dry place in the tunnel to sit down.

"I'll get it for you right away. You must have consumed a lot of energy." Henry immediately brought a few energy bars from the temporary camp not far away.

In the underground where you can't make a fire to cook, eating this energy bar is the most suitable way to quickly replenish your energy.

After finishing four energy bars in a few bites, Lin Yuan leaned against the stone wall and said, "I'll rest for 30 minutes. I'm a little tired."

After saying that, he closed his eyes and stopped talking.

In fact, the action of floating up directly without decompression was not completely harmless to his body, it was just that it was not shown.

At this moment, it felt like there were some invisible little bugs crawling back and forth in Lin Yuan's knee joints, elbow joints, etc., making him feel numb, itchy, and a little painful.

In addition, he also felt slightly dizzy, which was why his face looked a little pale when he just came out of the water.

These are the mildest reactions to decompression sickness. Lin Yuan knows that with his super strong physique and 20 times recovery speed, a 30-minute rest may be equivalent to two days of rest for others.

He would be back to full strength in a moment, and then he would be ready to go in the water again.

Rescue work is a race against time, and not a minute or a second can be wasted.

Laying the guide rope to the deep pool was just the beginning. There was a more dangerous section of the journey ahead. Even with his physical condition, he had to stay alert and be careful to deal with accidents that might occur at any time.

Lin Yuan had been looking at maps a lot during this period. He knew that the original entrance to the deep pool was 1735 meters underground, and the original exit was 1800 meters underground.

The height difference between the entrance and exit alone is 65 meters, and the passage to the deep pool is also a U-shaped path with the left side higher and the right side lower. The maximum diving depth is further increased to 85 meters!
Add to that the 15-meter drop from the current water hole entrance to the deep pool, and the total vertical drop reaches 90 meters. The water pressure at this depth will be quite challenging.

At 10 meters underwater, the water pressure is almost equal to the standard atmospheric pressure (1.03Kg/M2). Going any deeper, the human body will have to withstand water pressure that exceeds the standard atmospheric pressure.

This is why decompression sickness may occur after diving more than 10 meters.

As the diving depth increases, the water pressure increases by 10 standard atmosphere for every 1 meters of diving. At 90 meters, the water pressure is already superimposed with 9 standard atmospheres.

In such a water pressure environment, every time you raise your hands or feet, you will feel as if your body is hung with lead blocks, which is extremely heavy.

What made Lin Yuan even more troublesome was that the waterway from the original Camp 5 to Camp 6 was quite long and narrow, which meant that more inert gases would dissolve in his body.

Therefore, no matter from the perspective of duration or depth, it is impossible for him to float up directly without decompression as before.

After he overcomes all these difficulties and arrives at Camp 6, he will probably find that Camp 6 is also flooded, otherwise Meng Tao and others would not have been unable to return.

Then he would have to lay a guide rope to move forward, and how long this journey would be was completely unknown.

Lin Yuan closed his eyes and thought about the problems he might face next.

Henry, Old Peter and others sat down beside Lin Yuan silently. They all tacitly did not speak, allowing Lin Yuan to have a good rest.

Time passed quickly, and 30 minutes later Lin Yuan opened his eyes: "I've had a good rest."

"Wouldn't you like to rest a little longer? I know diving is very physically demanding." Old Peter said kindly.

Lin Yuan shook his head: "Hurry up, I don't know how much longer Meng Tao and the others can hold on."

After saying that, he began to take off his clothes again and put on the wet diving suit he had worn before.

"Idol? You still want to go in the water?"

Henry thought that after Lin Yuan rested, he would wait with them for the rescue supplies to arrive, and then everyone would go into the water together.

But from the looks of it, it seems like he's ready to jump into the water right away?
Lin Yuan nodded and said, "Yes, this time I plan to go directly to Camp 6 and then lay the guide rope forward.

If I'm lucky, I might be able to get ashore directly from the other side and start searching for Meng Tao and the others."

Old Peter said, "Lin Yuan, this section of the journey will be even longer."

Lin Yuan replied, "I know, but with the oxygen cylinders at Camp 5 as a supply, I don't have to worry about running out of oxygen."

This is true. There are 5 oxygen cylinders in Camp No. 100. Relying on the supplies in Camp No. 5, Lin Yuan has no problem searching Camp No. 6.

When he arrives at Camp 6, there will be new supplies at Camp 6 to support him in laying the guide rope from Camp 6 forward.

In addition to the long distance, you may need to consider the distribution of physical energy underwater, but you don't need to worry too much about oxygen consumption.

So Old Peter said, "Lin Yuan, I'll go in the water with you this time."

"Ok?"

"You need a helper to help you establish a temporary underwater supply point. Although my speed is a little slow, you don't have to worry about me for now. I will follow you slowly." Old Peter said seriously.

Hearing his words, Lin Yuan nodded in agreement.

It was just as Old Peter said, in addition to his own oxygen cylinder, he also needed to carry props for laying the guide rope, so he could only carry one more oxygen cylinder at most.

In order to find Meng Tao and others and bring them out safely, several temporary supply points need to be set up along the way.

Lin Yuan would definitely not be able to handle everything by himself.

"I'll go with you and partner with you," Henry said.

This is as it should be. Except for people like Lin Yuan who have unreasonable physical fitness, it is best to go cave diving in a group of two, so that they can take care of each other in case of accidents.

If one person acts alone, the danger will be much higher.

"Okay, then this time the three of us will go into the water together, and the rest will wait on the shore," said Lin Yuan.

Three people is the limit. If more people go into the water together, more oxygen cylinders will be consumed.

And these supplies were transported in with great difficulty.

Old Peter and Henry started putting on their diving suits. They both wore dry diving suits and carried an extra regulating oxygen tank than Lin Yuan.

After saying hello, Lin Yuan went into the water first, followed by Henry and old Peter.

After the three of them met underwater, Lin Yuan made a gesture, indicating that they would meet later.

Then he took the lead and swam forward quickly.

In the blink of an eye, he disappeared from the sight of Henry and Old Peter.

Henry and Old Peter were stunned when they saw this scene. They didn't expect Lin Yuan's posture underwater to be so agile, just like a fish, incredibly fast.

"Maybe Lin Yuan shouldn't be a movie actor. If he becomes a swimmer, he might end this sporting event with a record." Henry was speechless and thought to himself.

"I also know whether I should hope that Lin Yuan will fall in love with the cave diving project. Maybe he can overcome all the unknown difficulties, and then we will have no more challenges." This is what old Peter is worried about.

The two began to swim down one after the other along the guide rope.

When they finally reached the bottom of the water, they were surprised to find that it was not turbid.

Under normal circumstances, swimming through the forest source in front will stir up a lot of mud and sand in the water, resulting in extremely poor visibility.

But the current visibility only proves that Lin Yuan has been away from here for more than 5 minutes.

Henry and old Peter were both overwhelmed by the huge gap between them caused by Lin Yuan at the very beginning.

They had a vague hope in their hearts before, thinking that it was possible that Lin Yuan did not really arrive at Camp 5, but picked up an oxygen cylinder somewhere on the way.

After all, Lin Yuan’s previous behavior was simply too unreasonable and unbelievable.

But now that he had seen Lin Yuan's performance underwater with his own eyes, the last bit of hope he had was completely shattered.

The huge gap makes people despair, but after thinking it through, they feel relieved and more relaxed.

Old Peter gestured for Henry to follow, and the two of them followed Lin Yuan's direction.

……

In 20 minutes, Lin Yuan had passed through the first U-shaped channel, arrived at Camp 5, entered the "deep pool" and began to dive.

This is a diving channel with an angle of about 60 degrees, and it descends in a spiral shape.

After Lin Yuan walked around a few times, he began to complain in his heart: "This damn place, if it weren't for saving Meng Tao, he would never come here again.

Not only does it require a long, steep dive, but it also requires spinning in circles. I wonder if nature is playing a trick on me.”

Spending a long time upside down is obviously not a comfortable experience for humans.

And if you need to keep turning in circles while lying upside down, it would be even more torture.

Lin Yuan was sure that other people who came here to dive would feel dizzy.

As the diving depth got deeper and deeper, Lin Yuan looked at his pressure gauge and saw 8.5 atmospheres.

This means that he has reached an underwater area of ​​85 meters and is almost reaching the deepest point.

At this moment, he felt as if there were several big men sitting on him, making his hands and feet feel heavy.

His paddling movements were not as brisk as before, which would take him longer to pass this section.

After reaching the bottom, Lin Yuan continued to swim horizontally for nearly 10 minutes before re-entering the ascending channel.

After ascending 25 meters, Lin Yuan finally stopped and began his first decompression.

This time I can't rush up in one breath like before.

That would certainly feel good, but decompression sickness would never let him go.

It is absolutely impossible to stay underwater for such a long time at 90 meters and ignore the large amount of inert gas dissolved in the body.

For most divers, decompression is a very boring thing, just staying in the same place and waiting.

Staying in such an environment will not only make most people feel bored, but they will also feel an inexplicable depression and fear.

In the pitch-black water, there was only a little light from the headlamp, and there was silence in my ears, with only the occasional gurgling sound of flowing water.

Coupled with the high-intensity water pressure pressing tightly against the body, the feeling is very similar to that of a nightmare.

Lin Yuan looked at his watch. This time the decompression lasted for 10 minutes. He estimated that it should be about the right time.

So began the second stage of ascent.

This time he ascended 30 meters in one breath, and then had to stop and decompress for the second time.

It was still a 10-minute wait that felt like being in prison, and Lin Yuan could only sit in the water.

It's really boring and cumbersome, but this is the iron rule of diving.

Fortunately, his diving depth this time was not too deep, only 90 meters.

Decompression time increases exponentially with the length of time you stay underwater and the depth of the water.

If shallow enough, the decompression time can feel hopeless.

Take Dave, the prototype of the game "Diver Dave", for example. It was a diving trip in the Bushman Cave in South Africa that led to his death.

In just 17 minutes, he dived to a depth of 271 meters.

However, the total time for ascent and decompression is an astonishing 12 hours!

Can you imagine how uncomfortable it is to sit underwater for 12 hours?
And this is simply because he stayed underwater for only 271 minutes at a depth of 5 meters.

If it exceeds this time, he may need to decompress for more than 15 hours or even longer.

Fortunately, the diving depth of the "deep pool" is only 90 meters, which can greatly reduce the decompression waiting time.

Lin Yuan estimated that he would need to go through three decompression sessions, totaling 3 minutes.

Henry and Old Peter, on the other hand, needed five decompression sessions, totaling 5 minutes of decompression time.

Oxygen cylinders are needed for the journey, and for decompression. Now Lin Yuan can fully understand why it takes so many days to prepare the resources for a rescue team to go into the water.

He also had a deeper understanding of why Meng Tao and others were trapped and died deep in the cave:

The rising groundwater prevented them from reaching Camp 6 because they could not find the way without the underwater guide rope.

Without the oxygen tanks at Camp 6, they would never have been able to overcome the exhaustion of swimming in the long waterway and the oxygen consumption while waiting for decompression.

Therefore, for Lin Yuan, the most important thing is to make good use of the oxygen tanks in Camp 6 and lay the guide rope as soon as possible.

Otherwise, even if he found Meng Tao and others, he wouldn't be able to bring them out.

While Lin Yuan was thinking, the three decompressions were completed one by one, and then he finally returned to a normal swimming state.

The entire deep pool is about 1400 meters long, which can be said to be a double challenge to oxygen tanks and physical fitness.

Lin Yuan checked the consumption of his oxygen cylinder. Although he had replaced the oxygen cylinder once at Camp 5, the consumption was still close to one-fifth.

He estimated that Henry, Old Peter and others would probably need to consume more than half of their oxygen by the time they reached his position.

According to the rule of thirds, this is obviously very dangerous.

Without the oxygen support provided by Camp 6, they would be in danger at any time.

Henry and Old Peter were obviously aware of this during their communication before departure.

Lin Yuan was the first to swim so fast, partly because he hoped to get a few oxygen cylinders from Camp 6 and swim back to place them halfway.

An additional temporary supply point reduces the possibility of accidents for the two people.

This is also the work that the two need to complete for Lin Yuan in the next period of time.

That is to transport oxygen cylinders and set up several temporary supply points between Camp 5 and Camp 6.

Lin Yuan swam forward along the guide rope for about 5 minutes, and he finally found a red tent.

This should be the previous Camp 6.

Lin Yuan swam into the tent and found that the number of oxygen tanks was far less than that in Camp No. 5, only 33.

This is not surprising. After all, the difficulty of transporting supplies to Camp 5 and Camp 6 is completely different.

This is obviously not good news, which means that it will be quite difficult for this small amount of oxygen tanks to support Meng Tao and others to get out.

There are a total of five people including Meng Tao. After deducting the consumption of Lin Yuan and Henry Peter, I am afraid that each of them can only get four oxygen cylinders in Camp No. 5.

This means that when you get out, you must succeed in one go and cannot afford the extra consumption of the oxygen cylinder caused by failure.

Lin Yuan first picked up two oxygen cylinders, returned to the U-shaped channel, and set up a temporary supply point for Henry and Old Peter to use.

He then began to replace his oxygen tank and began to lay the guide rope forward.

In Lin Yuan's hands, there is no such thing as practice makes perfect.

Because of the two great gifts of extraordinary intuition and unity of body and mind, you can master it right away without any mistakes.

Therefore, the speed of laying the guide rope was quite fast, with about two meters of guide rope laid every two minutes as we moved forward.

After Lin Yuan worked back and forth for nearly three hours, he completed the laying of nearly 3 meters of guide rope, and the passage to the shore could be seen ahead.

So he first returned to Camp 6 to replace his oxygen tank, and then went ashore to look for Meng Tao and others.

When returning to Camp No. 6, Lin Yuan unexpectedly saw Henry and Old Peter.

Three hours after him, the two finally arrived at Camp 3.

Lin Yuan waved his hand, signaling them to follow him.

The three of them swam forward and finally emerged from the water following the guide rope.

The moment they came out of the water, all three of them took off their respirators and masks immediately.

"Great! It feels so good!" shouted Old Peter.

Even for an experienced diver, staying underwater for such a long time is somewhat uncomfortable, especially after going through so many boring decompressions.

"Meng Tao! Can you hear me?" Henry shouted loudly into the cave.

There was no echo in the empty cave, and no response from Meng Tao and others could be heard.

"The sound in the cave can travel very far. The lack of response means they are not nearby," said Henry.

"Let's go into the cave and take a look, and find them as soon as possible. Peter, I'm sorry to trouble you to stay and set up a temporary supply point." Lin Yuan said.

Old Peter nodded and said, "Go ahead, let's go to Camp No. 7 first."

Camp No. 7 is located 2100 meters underground. If Meng Tao and others are trapped and don’t want to starve to death, the best option is to go to the following camps.

From here, it takes about 4 and a half hours to reach Camp 7.

So Lin Yuan and Henry began to take off their diving suits and took out change of clothes from the waterproof bag they had just dragged behind them.

However, the clothes I can bring when going into the water are obviously not as many as before, and they look a bit thin.

Seeing Henry shivering slightly, Lin Yuan took off one of his coats and handed it to him: "Wear mine, don't catch a cold."

"You already have less clothes than me, how can you give me another one?" Henry shook his head and refused.

Lin Yuan smiled and said, "I can wear a wetsuit and go underwater for such a long time, are you still worried that I'm cold?"

So he stuffed the clothes into Henry's hands without any explanation.

Lin Yuan, who will not get sick, may consume more energy when it is cold, except for feeling uncomfortable from the cold, but he really can wear one less piece of clothing.

Feeling Lin Yuan's kindness, Henry put on Lin Yuan's coat, looked at Lin Yuan who was only wearing a single piece of clothing, and wiped his eyes silently.

After the three of them rested for a while, Old Peter stayed where he was, ready to go into the water soon.

Lin Yuan and Henry walked quickly towards the depths of the cave.

They must find Meng Tao and others as soon as possible.

It has been 15 days since they entered the cave, and they have been trapped for more than 10 days.

If we don't find them soon, we might be in real danger.

With an anxious mood, Lin Yuan and Henry walked at a very fast pace.

The two arrived at Camp 7 half an hour early.

When they entered Camp No. 7, they saw supplies neatly laid out on the ground, as if no one had touched them.

A bad premonition flashed through Lin Yuan's mind.
