24 February 438 in the Royal Calendar Era at 8.10 a.m

A white light flashed in Ergou's mind, and the handsome young man lying on the carpet, the innocent girl of flower age, and everything in this world disappeared.

It's over? The world fell into a dark silence.

Where am I? Is it drowning after holding your breath for more than 20 minutes? Strapped in water?

Could it be that it was a dream just now?

Thinking of this, feeling the cold and biting temperature around me, am I still underwater?

The second dog was startled, suddenly opened his eyes, and looked around in horror?

"Exhale~Inhale~"

Ergou found that he was still in the dark water, and he had sunk to the bottom of the pool with his limbs tied behind his back.

Hanazawa Coriander's Murphy mecha was still standing motionless at his side, and the tritium tubes on the mecha emitted a faint green light.

"Exhale~Inhale~"

"? What the heck? Are you still there, cilantro? ”

Ergou was horrified to find that not only was he not dead, but he was still breathing in the water?

It was unbelievable that he would be able to breathe in water with his lungs.

"Hanazawa parsley! Come out and explain to me, did you kill me?

Is all this another illusion? Another dream? ”

The process of human vocalization, which is probably the air flow exhaled from the lungs, reaches the larynx through the bronchi, causing the vocal cords in the larynx to vibrate, and the vibration produces sound, and then the mouth or nose controls the position of the voice.

And Ergou is breathing in water at this time, so what is exhaled from his lungs is not airflow, but complete liquid.

In this case, his speech is naturally slurred, and it is good to be able to make a sound.

"What are you shouting? 007！

Yawn ~ Disturb my sleep!

Anyway, you're the last soldier of the National Guard!

He is also a quasi-royal gladiator of our Chuxin Farm Club!

One drowning training session scares you like this? ”

The coriander Hanazawa in the mecha finally opened her mouth lazily.

"Woo woo wow ~ Have you modified my lungs?

Why can I breathe in water? Woo woo wow la~"

Ergou suddenly remembered, this feeling seems familiar?

"I don't hear you clearly, I know you have a lot of questions.

Now I'll give you the answer, so don't talk and listen to me quietly. ”

"Woo woo woo woo!"

"First of all, I apologized to you for being rude to you earlier.

After I take the enhancement potion, my emotions will be out of control, and I will be more irritable haha~"

"Woo woo woo woo!"

"Drowning training is actually scary to you, the liquid in the pool you are in now is not water, but the product of Shangfeng Technology, breathing fluid.

Perfluoronaphthalene derivatives have developed new respiratory fluids that use this raw material as a carrier for the active ingredient to penetrate into the human skin, allowing your lungs to get oxygen and remove carbon dioxide at the same time.

That is, you are in the current state, you can breathe normally in the breath fluid. ”

"Woo woo wow~"

"Haha~ Are you complaining about why I didn't say it earlier?"

"One purpose is also to test your apnea limit.

You know that there is a trivia about the human body?

It is impossible for a normal person to commit suicide by holding his breath.

Human breathing is neither completely controlled by autonomic nerves, like the heartbeat, nor by our consciousness, like the voluntary movement of skeletal muscles.

Rather, it is subject to both

mechanisms of common control.

Under normal circumstances, human breathing can be as free as you want to a certain extent, you can think fast, you want slow, you can think deep, you can think shallow.

This is due to the fact that the human brain will can innervate respiratory muscles such as the intercostal muscles and abdominal wall muscles that belong to voluntary muscles, and perform voluntary movements as if shaking an arm, which is called voluntary breathing.

However, there is a limit to how much human breathing can be arbitrary.

In terms of respiratory rate alone, it is difficult for most people to try to breathe rapidly for 1 minute in a row, because they will get dizzy in tens of seconds (respiratory alkalosis). If someone insists on persevering, you may soon fall into syncope.

How long can you hold your breath, experience tells us that the average person can usually only hold his breath for about 30 seconds. If you take a few deep breaths before holding your breath, most people can hold on for 1 minute or even 1 and a half minutes. Of course, it is impossible to suffocate yourself in such a short time.

Of course 007, you're a terrible guy, I just fell asleep, I didn't pay attention, you held your breath for at least 25 minutes just now, right? Quite amazing.

When it comes to nervous-controlled breathing, it's even more complicated, and it won't take an hour to finish.

To sum up, there are some neural reflex mechanisms in the human body, which cannot be bypassed by willpower, and a simple example is the knee jerk reflex, which you cannot control with willpower.

Oh~ I'm sorry, I forgot 007 you don't have legs now.

The so-called practice makes true knowledge. Throughout the ages, countless people have tried countless times, but they have never suffocated themselves.

Once the subjective will is held to increase the carbon dioxide in the body, the human body will automatically resume breathing. ”

Hanazawa Coriander has a lot of professional knowledge, and she is also talking eloquently at this time.

"Woo woo woo woo!"

"Yes, the process in 007 is that you rely on your own strong willpower.

After holding his breath for more than 20 minutes, he finally succeeded in suffocating himself.

And then while you're unconscious, your body activates the breathing machinery.

In the breath fluid, you come to life.

That's why I dare to lie to you like this, do training.

How's that? Did you see anything dreamy during your near-death experience? ”

Hanazawa Kana sat in the rack, and it was difficult to hide the joy in her tone, as if watching 007 eat deflated was something that made her very happy.

"Woo woo wow~"

Ergou wanted to say that his dream was very wonderful, real and unimaginable, and at this time Ergou even wanted to have another near-death experience to let him see what happened to the silver-haired boy.

"Again, you're asking, why do you have such boring training, right?

As I said earlier, there is a river in the mecha gladiatorial arena, so you have to guard against underwater combat.

One of the principles with cold training is that your vital maintenance system is broken in case of going into the water.

Even the enemy makes some unspeakable attacks.

It will inevitably affect your breathing.

At this time, your breath-holding time, and the mecha has our breath fluid. The problem can be solved.

Or maybe one more point of victory. ”

"Woo woo wow~"

Ergou wanted to say that it was so cold, he didn't have any clothes, and he was still in this humiliating posture of being tied with his limbs back.

Now that you know your apnea limit and how much you can adapt to this way of breathing, it's time to let yourself go and end this ghost training.

"Oops~ After all that, I'm sleepy again!

It's all your fault 007, forcing me to take medicine, and now I'm so weak!

I'll sleep a little longer~

Yawn~"

Saying that, Hanazawa Coriander is really going to sleep again.

"I'm going to ~ woo woo wah ~ how can you be like this?"

The second dog was in the breath fluid, and he could only struggle his body and shout in protest, but all this seemed to be in vain for Hanazawa Coriander.

The second dog was not in danger of life, and Hanazawa Coriander was naturally fearless, so she really fell asleep again.

Hanazawa Coriander slept this time, and when she woke up and took out the breath liquid, it was already four hours later.

"Vomit ~ Wow Woo ~"

The second dog, whose limbs were untied, knelt directly on the ground and vomited frantically and convulsed, the vomiting in the stomach was relatively good, and the discharge of fluid from the lungs was extremely uncomfortable.

Well? This feeling, so familiar? Is this it?

In Ergou's mind, it was like a lightning flash, and when Ergou woke up for the first time, wasn't this the case?

Ergou's body strongly remembers the feeling that there is fluid in the lungs and abdomen, and even the strange taste of this liquid.

This is a product of Shangfeng Technology, respiratory fluid?

The rare Adam gene in his body?

A perfect match for Shangfeng Technology's weapons, drugs and even prosthetic artificial organs?

All of this adds up, saying that Ergou has nothing to do with Shangfeng, who would believe it?

“007？ Have you vomited enough?

We've switched back to lunchtime and you'll have a break after eating.

If you don't force me to take the enhancement potion in the morning, I don't think you will have such a hard time. ”

“...”

Hanazawa Coriander's words, the second dog at this time couldn't listen to it at all, and in his mind, he was trying to recall the situation when he woke up.

I remember the electronic sound at that time, saying that the energy of the rescue chamber was exhausted?

Why is there breathing fluid in the rescue capsule? At that time, as soon as I came out, it was a dirt tunnel?

Judging from the whole space, it seems to be very different from the style of the underground base?

I'm so stupid, I've been looking for my own memories, my origins, isn't my birthplace the place where I should be investigated?

Ergou finally mastered the trick of the problem, but at this time he was still in the enemy camp and had no personal freedom at all.

“007？ What are you in a daze?

It can't be a problem with the lack of oxygen in the brain, right?

Well? Let's go back and wash and change clothes, eat and rest, and catch up with today's training progress in the afternoon! ”

Kana Hanazawa, who was dressed in a dark green pilot suit, jumped out of the mecha, pulled up the second dog who was kneeling in a daze, and walked towards the research institute.

"My, you've broken both hands.

There are also two mechanical legs, which were a little bent yesterday!

Don't you need to find Master Li Tianlin to help repair it?

Do you want to train in the afternoon? ”

Ergou was still thinking about his identity at this time, and Mu Ne let Hanazawa Coriander pull him away.

"Master Li Tianlin has been very busy recently, and Downton Abbey has entered the final process of property inventory and contract handover.

So there's nothing going on lately, and I won't look for Master Li Tianlin.

As for your limbs, you won't be training at a high intensity lately anyway.

It's all memory metal, I'll fix it for you when I go back in a while! ”

Hanazawa Coriander pulled the second dog in front and asked him to go quickly, and there was a good faint aroma on his body from time to time.

"Isn't it, sister? Haven't had any high-intensity training lately?

Do you say these things in good conscience?

Yesterday's cold training is that I insisted on coming back to life, if the average person died how many times, right?

I was stunned just now, didn't I die for a lifetime? ”

In the clean and spotless corridor of the research institute, Ergou shouted loudly in dissatisfaction behind him, and the state of the two at this time is easy to give people the illusion that this is a pair of lovers who are fighting.
