With half of her body submerged in the bucket, Noel just stood calmly with her eyes closed, preparing. Pen % fun % Pavilion www.biquge.info

Although she boasted about Haikou, if she was confident, she didn't have it at all - after all, she had never tried it.

Although I know some special knowledge for some reason, I have never practiced it all this time.

The brain quickly recalled those pieces of knowledge related to diving and breath-holding.

If you want to hold your breath for a longer time, the most direct way is to inhale pure oxygen before diving, so that the lungs can be filled with pure oxygen, so that you can use the metabolic effect of oxygen on the body more effectively.

It's a pity that there are obviously no such measures in this situation now, and even the doctor who monitors her physical condition in the water does not exist, and everything can only be done on her own.

I can only use some off-the-beaten-path techniques.

[]: A method of mandatory increase in lung volume by special methods. It is quick and easy to fill the lungs with one liter of air.

To some extent, this can also be said to be something like a secret technique, and of course it is quite dangerous. As long as one is not careful, the chance of the lungs bursting due to too much filled air is also quite high.

A flash of determination flashed in Noel's eyes: no matter what, now the only thing left is to do it.

According to common sense, the maximum limit of breath-holding time for the average adult is only 2.5 to 3 minutes. And because of her size, her lung capacity is below the average person, and judging from common sense, being able to hold her breath for 2 minutes is probably the limit.

If you want to extend it by 3 minutes, you can't do it without some special means.

"First, try to inhale until you can't inhale, and then start holding your breath."

This is the first step to normal breath holding.

Then, keep your breath held and open your mouth wide. Retract your tongue in, then close your mouth, taking care to leave as much space inside your mouth as possible to hold air. ”

At this point, Noel felt as if her body was filled with air, but she knew that it was not enough.

The air that fills the mouth does not help hold the breath for any second longer, it is simply a superfluous burden that strains the mouth muscles and distracts attention. So - they need to be turned into useful materials.

"Move your mouth as if you were gulping something – keep it doing so and use your tongue to shove the air inside your mouth into your lungs! It's like swallowing food whole into your mouth! ”

Nuo'er, who did this for the first time, only felt as if her chest was being squeezed from the inside to the outside little by little, but except for the feeling of suffocation, there was no pain yet, and it was obvious that it had not reached the limit.

"In the same way that you inflate blisters or balloons, you can compress air into your body like a pump with your mouth and tongue......

The feeling of swelling in her lungs was conveyed as if it were written in that book, and Noll relaxed slightly. But then she brought up the spirit: the next thing is the point.

"Once you've got the hang of it, you have to be careful about stuffing air into your stomach in search of relief because of the expansion of your lungs. Be careful not to make a mistake - repeat this action ten times. ”

That said, it was the standard for the average diver and professional breath-holding adult, and for Noir, after doing it for the seventh time, her lungs were already aching.

Common sense is screaming, if it continues, the body will definitely hurt, but!

No, it's not enough, go on!

Noel knew that what she was doing was not enough for her to hold her breath for 5 minutes, so she had to go beyond her limits.

Go on - for the eighth time!

No, it's not enough!

And so on -- nine times!

Already...... It's already the limit, no, it's not even the limit standard, and if it continues, the lungs that have begun to tear and ache will definitely explode.

"But it doesn't matter."

The pain disappears after diving because of the pressure in the lungs and the air is passively compressed – not in the deep sea, but at least it lessens. Now, how could she be afraid of a little pain?

No. 2 looked at him and nodded to him and then consciously squatted down, and the girl buried in the water also pressed the timer on the side, and then directly covered the steel lid without any mercy, and even locked it, and its bonding force would never be damaged in the slightest if it was not used with a tool such as a sledgehammer.

I don't know why, but for a moment in my heart, the thought of "fortunately not I'm locked in there" came to me, and Yi even scolded himself, but he didn't have any way.

It seems that because he is bored, No. 2 chats with Yi Geng while waiting.

"Although it is a sealed wooden barrel, there are still a few air outlets on the lid, otherwise the air inhaled by holding your breath will not be able to come out of the bucket full of water, hahaha."

Now is not the time to laugh!

There's a girl in the barrel who is challenging herself to a height above the limits of ordinary people! What kind of hard-hearted heart do you have to watch this scene with a smile!

No, I should say that everyone who participated in this challenge is crazy too!

In the water, people have almost no concept of time.

Even if you count the time all at once, it doesn't make any sense - because it's not you who decides the time of the dive, it's the person outside.

Even if you know that holding your breath for four minutes is already the limit, you can't get out.

On the other hand, using the brain to think will accelerate the consumption of oxygen, so it is better to think about nothing and simply wait silently and quietly under the water in the darkness where even the light cannot be seen.

Yes, just like that time......

Speaking of which, has it been five years?

That's 1,934 days when that translates to the number of days you left "there...... But what's the point of time?

Even with the so-called "Great Collapse", she doesn't see any change from her previous life. What's even more ridiculous is that she is still continuing her favorite and most hated game.

"Game" - What is it?

Isn't it a literal way to entertain and make people feel happy?

But why doesn't the "game" she comes into contact with feel the feeling that is recognized as "fun"?

Year after year, day after day, in that pure white, nothing-and-nothing room, not an inch could be left. The so-called "game" is going on all the time. I have no idea what those people's intentions are.

"null, that's great, this is already the world's top intelligent system to simulate chess, and you can completely seal "god", you are simply a miracle of mankind! ”

"Null, people who win too much can't survive in the outside world - it's such a world now. So you just have to stay here all the time. ”

"Null, why aren't you interested in anything but games? Your talents shouldn't be limited to such a small field......"

After all, what exactly is "null"?

Speaking of which...... That "chocolate", uh, no, the man called "Little One", when he called her "null", it didn't sound like those people.

Ah, I thought about it unconsciously, and sure enough, people are a reed of thought, and they always fall into thinking if they are not careful, what a troublesome creature.

Isn't there a way to live a relaxed life without thinking, just like before, as long as you play games every day, it doesn't matter if you don't think about anything.

But now, I often go hungry because I forget to participate in games or buy bento...... Ah, in that case, there seems to be a ready-made ...... next to it No, forget it, it always feels like a troublesome guy.

"Why hasn't there been any movement?"

Yi was watching from the outside of the bucket, but unfortunately because it was opaque, he couldn't see the situation inside.

"Haha, it's only been less than two minutes, if there is a situation now, then it is not good."

No. 2 smiled and looked at a calm wooden barrel: "When people are holding their breath while diving, if they want to stay as long as possible, they need to stay still as much as possible, and reducing their movements can reduce the rate of oxygen consumption, which is basic." Then, when the diver is strenuous and can't continue, the spasms and the mixed desire to survive when he desperately wants to breathe air - that's amazing. ”

No. 2, who was smiling as if he was intoxicated, was like a demon.

Yi Geng, who made such an evaluation, felt disgust for himself in his heart - what is the difference between him and this No. 2 by pushing such a child into such a dangerous situation?
