Reborn Action Star: Starting in Hollywood

"Mr. Lin Yuan, it is impossible to go out of the cabin for maintenance. The water pressure at a depth of 723 meters is unbearable for humans, not even marine creatures like bowhead whales." said Lieutenant Colonel Louis.

Lin Yuan nodded. "I know how terrifying 73 atmospheres of water pressure is, but if we can get out of the submarine, can we repair the hull? If all three watertight compartments are repaired, how deep can we recover?"

Lieutenant Colonel Louis said helplessly: "Forget repairing the three watertight compartments. As long as we can repair one watertight compartment on the right side and balance the left and right sides, we can float at least 3 meters.

If that's the case, the remaining two watertight compartments will be easy to repair."

"What do you mean?" Lin Yuan asked immediately.

"Once we surface to a depth of about 400 meters, the submarine's deep-sea pressure-resistant diving suits can be used. That will allow maintenance personnel to exit the cabin and repair the other two watertight compartments.

With four intact watertight compartments, the Virginia can continue to rise to a depth of about 4 meters, at which time it can release a communication buoy to call for help.

If only one watertight compartment had not been damaged." Lieutenant Colonel Louis sighed.

The Virginia is equipped with the most advanced pressure-resistant deep-sea diving suit, which is equipped with an ADS atmospheric diving system inside, which can keep the internal pressure of the diving suit consistent with the atmosphere.

The simple principle is to inject high-pressure gas into the compartment inside the diving suit through a high-pressure gas tube.

The expansion force of high-pressure gas counteracts the squeezing force of water pressure, and a balance between the two can ensure the safety of divers.

However, the deepest diving depth that this diving suit can support is only 450 meters, which is not suitable for the 723-meter seabed where the Virginia is currently located.

Thinking of this, Lieutenant Colonel Louis couldn't help but sigh again.

If one watertight compartment is less damaged, one watertight compartment on each side can also allow the Virginia to float to a depth of about 400 meters, so that maintenance personnel can go out of the compartment to carry out emergency repairs.

Unfortunately, there is no if. At a depth of 723 meters in the sea, no one can go out of the cabin for maintenance.

The difference of one watertight compartment is an insurmountable gap between life and death.

Lin Yuan was not affected by Commander Louis's frustration, but continued to ask: "Assuming that I can go out of the cabin to repair it under the water pressure, how can I repair the submarine's watertight compartment hull?"

"Impossible, no one can withstand such water pressure, it's 73 atmospheres!" Lieutenant Colonel Louis exclaimed.

"Lin Yuan, don't be so depressed!" Depp shouted in surprise.

"It's too dangerous. Don't even think about taking the risk. If you fail, you won't have any chance to regret it. The water pressure will crush you in an instant." Meng Tao also said.

"Lin Yuan, you still have a chance of survival if you stay on the boat, but you will be dead if you leave the cabin." Director Cohen also advised.

At this moment, the three members of the crew reached a consensus and they all urged Lin Yuan to take the risk.

This was naturally out of concern for Lin Yuan, fearing that he might suffer an accident, but it was also out of consideration for his own safety.

As long as Lin Yuan is still on the boat, they have a backer.

Even if the worst-case scenario arises and they have to find a few victims, they can still rely on Lin Yuan.

But if Lin Yuan really went into the water and unfortunately suffered an accident, they would be left alone and helpless.

Lin Yuan shook his head: "Let's not talk about whether I can withstand the water pressure. Assuming I can get out of the cabin, how can I repair the watertight compartment?"

Lieutenant Colonel Louis said, "Since you're curious, I'll tell you. The three watertight compartments with minimal damage only have a small crack less than two meters long. Just use an electric welding gun to weld it shut."

"Spot welding gun? Can you weld underwater?" Depp shouted.

"Isn't it said that water and fire cannot coexist? How can enough heat be generated underwater to melt the welding metal?" Director Cohen also asked.

Meng Tao took over the topic and said, "Haven't you heard of a profession called underwater welder?"

"No!" They both shook their heads.

"Welding is possible underwater, but it's very dangerous. Underwater welders are known as the most dangerous type of workers, and of course, they also have super high salaries. Even in China, annual salaries can reach over one million yuan," said Meng Tao.

"Due to limited conditions, the only option for submarine underwater repairs is the most dangerous wet welding," Lieutenant Colonel Louis continued.

"Wet welding?" Depp asked. "Is it dangerous?"

"Of course it is very dangerous. It is said that the death rate of the mission is as high as 0.3%." Meng Tao said.

Lieutenant Colonel Louis briefly explained that this is wet welding, which is called "underwater emergency repair cornerstone technology."

In fact, humans discovered very early that electric arcs can continue to heat and burn underwater, which led to the emergence of underwater welding technology.

It mainly relies on a voltage of 220 volts or 380 volts. The current is increased through the pressure reducer of the welding machine, and the huge arc heat generated by the electricity is used to melt the welding rod and the steel to be welded, allowing the two to melt and combine together.

Just to achieve stable welding underwater, the welding rods must be specially treated.

A thick coating will be applied to the outside of the welding rod, and then paraffin or other waterproof substances will be infiltrated to make the coated welding rod waterproof.

During underwater welding, the high heat emitted by the welding rod will cause a continuous generation of bubbles at the weld.

The continuous bubbles will displace the surrounding seawater, forming a dry and enclosed space, so that the welding purpose can be achieved.

In addition to special treatment of welding rods, the problem of electric shock to operators underwater also needs to be solved.

Seawater is a very good conductor, and accidents where the current from spot welding rods accidentally strikes the operator, resulting in underwater deaths, often occur.

Therefore, operators must wear special insulating diving suits, and the welding machines they carry with them must also be wrapped in thick insulating skin.

In addition, the electrodes need to be coated with wax and waterproof paint.

But even with all the protection measures in place, many underwater welders die from electric shock every year.

The mission mortality rate reached 1000%, which means that for every 3 operations, there would be fatal accidents.

This probability is basically the same as being an infantryman and fighting on the battlefield.

The average death rate of soldiers in a combat mission during war is about 0.3%.

Therefore, the high risk of this job requires employers to offer high salaries to make practitioners willing to take such high risks.

Three thousandths?

Maybe it is quite dangerous for people living in peace, but in Lin Yuan's opinion it is not a problem at all.

A mortality rate of 0.3% translates to a safety rate of 997%/1000.

Among those extremely thrilling shots he made in the movies over the years, which one had a success rate of over 997 out of 1,000?
Eighty percent is a high probability of success for him.

Not to mention that when he first started, he often forced his way forward with only a 50% success rate.

Lin Yuan replied, "If EVM maintenance only involves welding, I think I could give it a try. I worked as a welder for a while before my debut, so I have experience with the basic techniques of welding: arc striking, arc movement, and arc extinguishing."

Meng Tao: “…”

Director Cohen: “…”

Depp: “…”

The three of them were completely speechless. Is this a problem with welding?
The key is, can you withstand the water pressure at 723 meters under the sea?
Do you really think you are made of steel?
The world record for scuba diving in human history was set by Egyptian Ahmed Gabre.

Relying only on oxygen tanks and an ordinary dry diving suit, he successfully challenged the world record of diving depth of 332.35 meters.

In order to challenge this record, he trained for four years.

During the challenge, the entire dive took him only 12 minutes, while the return took a full 15 hours (with staged decompression).

Perhaps there are people in this world with better physical fitness than Ahmed Gabre, but the world record for normal human scuba diving will probably not exceed 350 meters.

It can be said that a depth of 350 meters is probably the limit of water pressure that the human species can withstand.

If you want to challenge deeper diving depths, you must use a fully enclosed pressure-resistant diving suit.

However, the records created in that way cannot reflect human physical fitness, but rather the level of technology.

Lieutenant Colonel Louis said helplessly, "Mr. Lin Yuan, the pressure-resistant diving suits on our boat can't withstand the water pressure at such a depth. And it's unimaginable for the human body to resist such water pressure."

Lin Yuan said, "I know the principle of ADS pressure-resistant diving suits. They rely on inflation to resist water pressure.

The advantage is that divers are quite comfortable within the range and do not have to bear any water pressure at all.

But the disadvantage is that once the performance exceeds the limit, it will be completely useless and will not have any stress-relieving effect.

So I can’t use this kind of pressure-resistant diving suit.”

"So what kind of diving suit do you want?" asked Lieutenant Colonel Louis.

"Is there a liquid-filled pressure-resistant diving suit on the Virginia?" Lin Yuan asked.

"You want to use a liquid-filled pressure-resistant diving suit?" Lieutenant Colonel Louis asked in surprise.

The Virginia is naturally equipped with this pressure-resistant diving suit. This diving suit has a double-layer structure. The outer layer is a strong, non-stretchable pressure-resistant material, and the inner layer is a stretchable waterproof diaphragm. There is a liquid interlayer between the inner and outer layers that leads to various parts of the body.

The layers are connected by tubes, two of which run from the neck to the ankles, and then separate to the instep and heel respectively. Others lead to the outside of the arms, shoulders and waist.

There is a special pressure-resistant liquid inside the tube, and the entire suit contains 1.3 liters of pressure-resistant liquid.

Under high pressure, the special pressure-resistant liquid in the internal pipes of the clothing will be squeezed and begin to expand to resist the pressure transmitted from the outside, thereby reducing the water pressure.

The disadvantage of this pressure-resistant diving suit is that it is relatively bulky and cannot completely isolate water pressure like the ADS pressure-resistant diving suit.

There is only one benefit, that is, no matter what the water pressure environment is, the impact of water pressure can be reduced to an appropriate extent.

For Lin Yuan, the ADS pressure-resistant diving suit that exceeds the limit is worthless, and the seemingly useless liquid-filled pressure-resistant diving suit is his real savior.

In his opinion, the limit of normal human physical fitness is to withstand the pressure of 350 meters of water, which is probably equivalent to the dual attributes of Constitution 20 and Strength 20. However, his current strength has reached 23 points, surpassing the human limit.

His physical fitness has reached 30 points. All his body tissues are far stronger than those of normal people. In addition, he has activated his legendary talent, which has brought him super physical recovery ability. This makes Lin Yuan believe that he has a chance.

Before entering the Kalonos Cave for rescue, in order to prepare for possible diving activities, Lin Yuan studied relevant diving knowledge in depth.

He learned that this liquid-filled pressure-resistant diving suit can reduce pressure by about 10 atmospheres.

In this way, the atmospheric pressure he needs to withstand is reduced to 63 atmospheres.

Although the pressure is so strong, it is still unbearable for normal people.

There is no difference between 73 atmospheres and 63 atmospheres, both are beyond the limit.

But for Lin Yuan, this might be the magical tool that allows him to cross this limit, so he said solemnly:

"Don't you really not believe me? How many impossible challenges have I completed over the years?"

"It's not that I'm obsessed with past glory, nor that I'm arrogant and don't care about my own safety. It's just that if I don't try, I'll just sit there and wait for death."

"Let me try. I can't really force everyone to kill each other, right? I hope everyone can return safely."

When Lin Yuan spoke, his voice was sonorous and powerful, revealing an unquestionable confidence.

His eyes were full of determination, which made Lieutenant Colonel Louis and others involuntarily have an idea:
It seems that Lin Yuan can really do it!
Should he at least try?

But how to try it?

It's too dangerous. Will you die if you try it?
Lin Yuan guessed their thoughts and asked, "Is the escape pod intact?"

"No, both escape pods are intact and can be used normally," said Lieutenant Colonel Louis.

"Then let me try. I'll try to put on the diving suit and enter the escape capsule. You connect to the external water pressure and let me feel it. If it still doesn't work, then... then at least it will be easier for you to help me collect the body." Lin Yuan said without hesitation.

There is no need to seek luck at this time. Only by facing life and death bravely can you have a better chance of survival.

Lieutenant Colonel Louis looked at Lin Yuan for a long time, his expression quite complicated.

As an experienced submarine commander, it is his responsibility to ensure Lin Yuan's safety at this time.

But the reality is completely the opposite. These professionals can do nothing but watch Lin Yuan risk his life to create a possibility for them.

Ashamed!
It's so shameful!
Lieutenant Colonel Louis solemnly saluted Lin Yuan and said, "Mr. Lin Yuan, I feel very guilty.

As the captain of the Virginia, you are now facing a life-and-death crisis, and you, the guest, are asked to charge into battle.

But I also know that we can never do what you can do.

I make a promise to you: regardless of whether you succeed in this challenge, I will protect the lives of the crew members and will never let them become victims."

Lieutenant Colonel Louis knew that this was all he could do, but it was what he had to do.

Regardless of whether Lin Yuan is able to carry out maintenance outside the cabin, he has already made sacrifices on behalf of the "King of Spy 2" crew.

If the escape attempt fails, someone will have to bear the consequences, and it should be the officers and soldiers of the Virginia.

Lieutenant Colonel Louis made up his mind that even if he had to sacrifice himself, he would never let the crew members become victims.

Lin Yuan immediately understood what Lieutenant Colonel Louis was thinking. He nodded and said, "Mr. Louis, I believe in your promise. Time is running out. Please help me prepare a diving suit. I must first test whether it can withstand the water pressure."

"Understood! I'll make preparations right away!" Lieutenant Colonel Louis saluted.

After saying that, he opened the restaurant door and trotted towards the warehouse.

As Lieutenant Colonel Louis left, Depp immediately grabbed Lin Yuan's hand and asked:
"Lin Yuan, do you really want to leave the submarine? Think about the enormous water pressure outside the submarine. Even the steel hull of a submarine can be crushed. Aren't you afraid that your head will burst like a balloon?"

Lin Yuan shook his head. "The human body has a high water content, unlike a submarine which is hollow. Its pressure resistance is far superior to that of a hollow body. I'm just testing it in the escape pod. If I really can't bear it, you can immediately decompress and rescue me."

"But if you can't hold on, even if you don't die on the spot, you'll probably be seriously injured. At this time, we will completely lose our ability to resist. What if they take the opportunity to attack us? You don't believe Lieutenant Colonel Louis' promise, do you?"

Depp didn't quite believe Lieutenant Colonel Louis' promise, especially one that involved life and death.

If they want to save the four crew members, it means that the Virginia must lose these four lives.

It was too cruel. Depp didn't believe that Lieutenant Colonel Louis would keep his promise.

"Shut up! Soldiers have their own honor and pride. If they make a serious promise to you, you'd better believe it.

Otherwise you are trampling on their pride and then don't blame them for not keeping their promise.

"Do you think soldiers are like you so-called Hollywood celebrities, who just talk nonsense?" Meng Tao scolded.

Meng Tao knew Depp quite well. He was well aware that Depp had seen the intrigues in Hollywood over the years. One moment he could be as good to you as a brother, promising to be with you forever, and the next moment he could stab you in the back for his own interests.

There is no way. The entertainment industry is a world of fame and fortune. If you are immersed in it for a long time, you will inevitably become snobbish and value interests more than promises.

But soldiers are different. They are a group that must rely on their partners.

If you want to survive on the battlefield, you must trust your teammates with your back.

Only by honoring your promises and trusting that your teammates will have your back, can we all overcome difficulties together.

Lin Yuan's behavior was equivalent to launching a fearless charge in the face of a life-or-death crisis.

He turned his back to Commander Lewis and all the officers and soldiers of the Virginia.

Lieutenant Colonel Louis understood this principle, so he immediately made his own promise.

This is an unspoken covenant between men. If you question this, it is not only denying all the officers and soldiers represented by Lieutenant Colonel Louis, but also denying Lin Yuan's efforts.

That's why Meng Tao severely reprimanded Depp.

Seeing Meng Tao so serious, Depp could only mutter in a low voice: "You all believe it, so I can only believe it too. I hope you are right."

Lin Yuan patted Depp's shoulder and put his other arm around Director Cohen: "Don't worry, I will successfully conquer this challenge. I will bring you back safely. Trust me!"

"Well, I believe you."*3
Meng Tao, Director Cohen and Depp stood up and said.

After a while, Commander Louis returned to the restaurant wearing a liquid-filled pressure-resistant diving suit, accompanied by two other submarine sailors.

Obviously, the two submarine sailors already knew what Lin Yuan was going to do.

They didn't say anything, but the respect in their eyes was obvious.

"Mr. Lin Yuan, this is the highest-specification liquid-filled pressure-resistant diving suit on the Virginia. The internal liquid filling reaches 2 liters. I checked it personally to make sure it is safe and usable." said Lieutenant Colonel Louis.

"I believe you. Now please teach me how to wear this diving suit." Lin Yuan said.

Lieutenant Colonel Louis waved his hand, and the two officers immediately stepped forward and began to help Lin Yuan put on his diving suit.

The first thing to do is to take off all the clothes. Lin Yuan only left his underwear on and put his entire body into the diving suit.

This black liquid-filled pressure-resistant diving suit is like a one-piece suit, and the outer layer is made of a very strong, non-stretchable pressure-resistant material. It can be said that it is quite difficult to wear.

Lin Yuan felt that putting on this diving suit was even more uncomfortable than the fireproof suit he wore in the Canadian fire.

This is very strange. Logically speaking, fireproof clothing is obviously much heavier and should be more uncomfortable.

But it is this kind of liquid-filled pressure-resistant diving suit that is more uncomfortable to wear.

There is a contradictory feeling of being both soft and hard.

The disorder naturally comes from the pressure-resistant liquid in the interlayer. When you try to walk, you will feel that the liquid is swaying all over your body.

The hardness comes from the outer layer that is so strong that it feels hard, making people feel as if their hands and feet are tied with a rubber band, making it very inconvenient to move.

This mixture of soft and hard feelings, coupled with stiffness and a loss of balance in the body's center of gravity, brought about an extremely indescribable discomfort.

There is no other way. No matter how uncomfortable it is, you have to wear it. It is to save your life.

With the help of two officers and soldiers, the donning of the liquid-filled pressure-resistant diving suit was finally completed.

Lieutenant Colonel Louis stepped forward again and personally checked the details.

"No problem, shall we go?"

"Well, let's go!"

Lin Yuan and his group walked towards the escape pod.

At this moment, everyone is in a heavy mood.

It is called an escape pod, but at this moment it may very well be acting as a "death pod".

If Lin Yuan couldn't withstand the water pressure, the worst result would probably be that he would die instantly.

Lin Yuan now looks like a suicide squad member holding a blasting tube and rushing straight into the enemy's fortress. People can't help but respect him and worry about him.

When Lin Yuan and others arrived at the escape hatch, they were surprised to find that the corridor was full of officers and soldiers of the Virginia.

Judging from the number of people, I'm afraid that except for those who are on duty and cannot leave their posts, everyone else has come.

"What is this, everyone?"

"We can't be heroes, we can only stand behind you." (End of this chapter)
