Global Racing: My extreme operation show shocked the audience

Lin Hai was dumbfounded:"Chen Yi said no more equipment, what does that mean?"

Su Ya's eyes widened:"Did he mean to directly hold his breath for cave diving?"

Liu Jing shook his head:"How is this possible, even if it is 30 meters? Free diving is also very difficult, not to mention that the 30-meter cave is so winding and long, how can you hold your breath and swim through it?"

Yan Xueqi took out her mobile phone, checked it, and said:"The longest record for free diving without fins is only 140 meters. The longest recorded distance recorded with flippers is only 190 meters. Moreover, this record was actually measured in a swimming pool, not 30 meters deep sea water. Moreover, this 30-meter cave is winding and winding. If it were straightened out, it would probably be less than 190 meters. Said, there are 400 meters."

The audience in the live broadcast room also talked about it.

"Isn't it possible? Chenshen doesn't really want to hold his breath and swim over, does he?"

"This is impossible, this is beyond the limit of human physical fitness"

"Even though Chen Shen is awesome, he mainly relies on his skills. In fact, his physical fitness is still within the normal range of human beings, but this one is definitely beyond human limits."

Diving is divided into scuba diving and free diving.

Scuba diving is the most common form of ocean diving. Simply put, you go down with a tank and a breathing system device. You can still breathe even if you go into the water.

Free diving is What most people often play in the swimming pool is purely to hold their breath, but most people can only experience holding their breath at ordinary depths, and cannot experience it below 10 meters.

Anyone who has studied physics knows that for every 10 meters of depth underwater, there will be an increase in atmospheric pressure. Under constant temperature conditions, the volume of gas is inversely proportional to the absolute pressure. At a depth of 10 meters, our lungs will be compressed to half of their usual size. The further down we go, the more compressed they are. A depth of 30 meters is no longer something that ordinary people can bear.

Photographer and work Although the personnel did not understand what Chen Yi was thinking, they immediately put on their equipment and chased after him, including two diving instructors and a professional diving rescuer.

They saw that Chen Yi had arrived at the cave location. There were signs on the water surface and he could still swim underwater. Seeing the light, it was very easy to recognize. Chen Yi lay on his back on the surfboard and began to take a deep breath. He couldn't breathe underwater during free diving, so he could only hold his breath on his own. Naturally, he had to take a full breath at the surface of the water. The fuller the better.

When everyone saw his actions, they couldn't help but gasp. He seemed to really want to hold his breath and dive with one breath. How could this be possible in the first place?

"Chen Yi, have you read it wrong? This 30-meter cave is at least 400 meters long. It is impossible to swim through it while holding your breath."The staff advised.

Chen Yi didn't listen at all and continued to take deep breaths.

The staff had no choice but to prepare for rescue. They had already begun to discuss. After a while, Chen Yi couldn't hold his breath anymore. How should he cooperate with the rescue and what should he pay attention to to avoid explosion. Lungs.

Chen Yi felt that he was almost done. He took a final breath, turned over, got off the surfboard, and then swam straight down with his head down.

The audience in the live broadcast room were all nervous.

"Let me go, Chenshen is really going to hold his breath and swim over there"

"Even if it’s Chen Shen this time, I think it’s absolutely impossible"

"Fortunately, there are rescuers and oxygen bottles. If you can't hold it in any longer, you can breathe in oxygen to save your life."

"Let me correct you here, that is not an oxygen bottle, but a compressed air bottle. This is a common sense mistake. In addition, free divers cannot inhale the air from the air bottle at will when underwater. I also saw a news a while ago. In an aquarium, a free diving girl inhaled the air from the air bottle underwater. When she came up, , directly exploding the lungs, vomiting blood, coma, and convulsions. This is because during the dive, the lungs will compress. After inhaling, the lungs will expand underwater, and then when you come up, the lungs will expand like a balloon. There are a lot of things here that are very dangerous and not so casual."

"Doesn’t that mean that there is danger even if there is rescue?"

"Of course, I have seen those extreme free diving challenges, all with professional rescue teams around them, but some of them still died on the spot."

"Scuba diving is dangerous, let alone freediving."

It's okay if you don't say it. The more you talk about it, the more nervous the audience becomes.

I saw Chen Yi continue to dive, swinging his legs and moving his body, which will accelerate the consumption of oxygen in the body, but if you want to get rid of the loss of buoyancy, you must swim in the early stage. This is why free diving can be divided into whether it has counterweights and whether it has fins. If there is a counterweight, the gravity can accelerate the descent. If there are fins, it can also swim faster. Therefore, constant weight without fins is the most difficult part of free diving. Class.

In order to save oxygen, Chen Yi tried his best to be as calm as possible without making any unnecessary movements. Every movement played a good role.

He took his time and dropped to a depth of 10 meters, 20 meters, 30 meters......Perhaps for the convenience of filming, the program team installed lighting equipment on the cliff of Moon Island, which is a good guide.

When you reach 30 meters, you can see a hole on the cliff, which should be Cave No. 1, but Chen Yi, there is no Instead of getting in, he continued and dived down.

The diving instructors and photographers following him all had their eyes widened. They were anxious, gesturing wildly, and looked at the audience in the live broadcast room, who also gasped. cool air

"Oh my gosh, he's going to dive into a 110-meter cave."

"How is this possible? This is even more impossible. Although this cave goes straight up and down, greatly reducing the distance, at a depth of 110 meters, the pressure will crush a person's lungs."

"If you go down to this depth, you can't even save yourself."

"I just checked and found that the deepest free diving record without weights or fins is 72 meters. This depth is already terrifying. Most people will definitely die if they dive this deep. Even professional athletes have died during the challenge, but what Chen Shen is challenging now is 110 meters."

"Oh my god, we still underestimated Chenshen’s madness."

Lin Hai, Liu Jing, Su Ya, and Yan Xueqi were all stunned. Director Xie Kui was so frightened that he jumped up again. He had already thought about this level. The 30-meter diving might not be difficult for Chen Yi. He You may choose to dive to 110 meters, but that refers to scuba diving, not free diving. Do you know how much water pressure you have to withstand if you dive into the 110-meter-deep sea with just one breath? 12 atmospheres of pressure, that’s a full 12 Atmosphere pressure.

Xie Kui was already thinking about whether to ignore the rules and let the diving instructor bring Chen Yi up, but he was a little worried that Chen Yi would not be willing to do anything but cause interference.

At this time, Chen Yi, who had reached 30 depths, because of the pressure Due to the relationship, the volume of his lungs is only a quarter of the normal size. He is gradually losing buoyancy and entering the next stage of free fall, so he does not need to move anymore, and his body will naturally accelerate downwards and sink.
