Chapter 685 Breath Hold Challenge
As soon as Lin Yi finished speaking, Instructor Li immediately poked his head out, pointed to the corner of the deep water area and said, "Brother Lin, there is a man holding his breath over there. It seems that he has been holding his breath for a long time. It's quite interesting."

It's just holding your breath, what's so interesting about it, it's like who hasn't held your breath yet.

Lin Yi didn't care, but the security officer took the initiative to say: "We have an Internet celebrity breath holding competition here. As long as you hold your breath for more than 5 minutes, you can get free tickets. Do you two want to try it?"

Lin Yi waved his hands again and again when he heard the word "Internet celebrity", "No need, the tickets are not expensive, we just pay honestly."

Instructor Li knows what Lin Yi is worried about, but the current troops already have their own short video accounts. Short videos are now the mainstream entertainment software. This is an opportunity for the people to understand the army, so Instructor Li is not very Afraid of hearing the word "Internet celebrity", he persuaded: "Brother Lin, I know you are capable, so you can try it out. We all wear casual clothes, so you don't have to worry so much."

Lin Yi was worried about the impact on the one hand, and more importantly, holding his breath for 5 minutes is not a short time. For ordinary scouts, holding his breath for two to three minutes is already the limit, and he has never specially practiced holding his breath , It is definitely not an easy task to hold back for 3 minutes.

Instructor Li saw that Lin Yi didn't answer him, so he didn't force Lin Yi. After all, Lin Yi was the leader and he was his subordinate, so he didn't dare to persuade him anymore, but he was very interested in this, so he said: "Comrade , I'll try it."

Hearing this, the security officer immediately took out a timer and a mobile phone to take pictures, and said while taking pictures, "Today this handsome guy is going to challenge our internet celebrity breath holding competition. Let's see how long he can hold his breath."

Then he looked at Instructor Li: "Handsome guy, do you have the confidence to complete our 5-minute breath-holding challenge?"

Instructor Li said generously: "I haven't challenged it yet, but I want to try."

The security officer immediately said: "Okay, I'll count down to three, and let's start the challenge."

After counting the number three two one, the security officer pressed the timer, and Instructor Li also dived into the water. In the first two minutes, Instructor Li was fine. It seemed that the water quality was very good, but after two and a half minutes Zhong, the expression was obviously different. Lin Yi knew that Instructor Li couldn't hold on any longer.

Sure enough, after seven or eight seconds, Instructor Li surfaced, panted heavily, and said while panting: "This is more difficult than holding your breath in the washbasin. I thought I could hold it for 3 minutes, no. I can't bear it when I think it's only two minutes and 40 seconds."

At this time, the security officer said a long standard short video speech to the mobile phone, and then looked at Instructor Li: "Handsome guy, why don't you try again, this time for two minutes and 40 seconds, maybe you can stick to it next time It's been 3 minutes."

Instructor Li waved his hand: "Forget it, forget it, even if you can hold on for 3 minutes, it's still far from 5 minutes. It's meaningless. It seems that I can't enjoy this ticket."

At this time, Lin Yi took the initiative to say: "Well, do you want me to try it?"

The security officer himself has the task of shooting short videos. After all, this kind of exposure is needed on the short video platform now. Instructor Li does not intend to continue. The security officer is naturally lacking in interest, but when he heard that Lin Yi wanted to take the initiative to challenge again, he quickly Then he said to the phone: "Another handsome guy is about to challenge our internet celebrity to hold his breath again, let's see if he can succeed this time."

After finishing speaking, he looked at Lin Yi: "Then I will count down to three."

Lin Yi waved his hand: "Don't worry, let me take a deep breath."

The security officer was naturally not in a hurry, and just said to the mobile phone on his own: "It seems that this challenger is an expert, he knows that he should take a deep breath before holding his breath, and we will give him a little time to hold his breath when his body reaches an oxygen-enriched state." , to see if he can challenge successfully."

Instructor Li didn't know why Lin Yi did this at first, but when he heard what the security officer said, he immediately understood, and quickly gave Lin Yi a thumbs up, and praised: "It's still Brother Lin who has the ability to know how to take a deep breath. "

Lin Yi has never specially practiced holding her breath, how could she know how to take a deep breath, besides, how could she give you a chance to take a deep breath when swimming with arms.

That's because the instructor just kicked you into the water, and then let you swim desperately.

Lin Yi just saw the person who was holding his breath underwater just now dived out, and then began to take exaggerated deep breaths. Lin Yi is not stupid, he knows how terrible the vital capacity of a person who can hold his breath in the water for so long, even if it is He ran out of oxygen underwater and needed to surface for a quick breath, but it wouldn't take that long to take a deep breath.

He took a deep breath for at least 5 minutes, so Lin Yi concluded that taking a deep breath before holding his breath must be very effective for holding his breath, otherwise he would not have done it.

Lin Yi took a deep breath at this time and it took a long time, especially the process of exhaling was a generation longer than inhaling. Lin Yi didn't understand why he took such a deep breath. This is the breathing method he observed, but don't say, this deep breath, It does make you feel more comfortable.

Lin Yi gestured ok to the security officer at this time, the security officer saw this and immediately said to the camera: "Then let's start the timer."

As the security officer pressed the timer button, Lin Yi also dived into the water. Lin Yi's physical fitness had surpassed that of a junior special soldier, so his lung capacity should not be underestimated.

People who can swim normally can hold their breath underwater for no more than 3 minutes, but it is not impossible for specially trained people to reach 4 minutes.

Lin Yi estimated that his lung capacity was enough to last for 4 minutes. As for how long he could last, he had no idea.

But Lin Yi knew that the most powerful breath-holding person in the world could persist for 15 minutes. Of course, a professional breath-holding person like him would inhale oxygen instead of air.

Of course, the oxygen here is not pure oxygen. In fact, the human body cannot withstand pure oxygen. The oxygen provided by the oxygen mask that everyone sees in the hospital has a concentration of 30-40. Most of what he inhales is the same. .

The oxygen content in normal air is 21%, so the oxygen they inhale is at most twice as high as the air, but that person can persist for 15 minutes, which is really incredible.

According to this data, the person who inhales air should hold their breath for seven or eight minutes. But Lin Yi knows that this algorithm may not be accurate, but it should be pretty close.

With the support of this data, Lin Yi's confidence suddenly soared. He thought that his lung capacity was very strong. Even if he could hold his breath for less than 8 or 5 minutes, it should be possible to hold on for [-] minutes.
