From Demon Slayer: Thunder Swordsman

"You should rest well for a few days and don't do such reckless things again."

Jiujo Tachibana nodded.

Upon seeing this, Ubuyashiki Yoya took the team members who came to visit Kujo Tachibana and left.

...

Five days later, Kujo Tachibana was discharged from the hospital again and returned to his own house.

From then on, Kujo Tachibana stayed at home, recalling the memories of his past life day and night.

At the same time, he was thinking hard about how to solve the problem of his lung injury.

While seeking other solutions.

Half a month passed in a flash.

But at this time, Jiujiao Ju still had no clue.

Feeling his physical fitness gradually deteriorating, Kujo Tachibana knew that he had to solve or delay this problem first.

Otherwise, if time goes on any longer, I'm afraid he will really become a sickly person.

Early the next morning, Jiujo Ju got up early and started fighting.

In the past, everyone could learn Tai Chi, a set of boxing techniques that did not require high physical fitness and had very gentle and soft movements.

This is a set of "Tai Chi" that Jiujiaoju downloaded from the computer in an Internet cafe when he was a teenager on Blue Star and dreamed of becoming a martial arts hero.

As for whether the practice was effective or not, that can be seen from the way he died in his previous life. However, this does not mean that this set of Tai Chi is completely useless.

All we can say is that the young man was too "restless" and didn't have the determination to persevere.

Of course, Kujo Tachibana did not expect that practicing Tai Chi would turn him into a top master.

Not to mention whether that kind of power actually exists, even if it does exist, without the guidance of a famous teacher, it would be impossible for Kujo Tachibana to become a peerless master by practicing the widely circulated "Yang Style Twenty-four Forms Tai Chi".

The Yang Style 24-posture Tai Chi is an "official" certified Tai Chi.

Many of the original moves have been replaced and modified, and the only function left is to strengthen the body.

What's more, with his current physical condition, even if he really had a peerless martial arts skill, it would not have any effect.

You must know that as long as you are a human being, you need to breathe. If you have problems breathing, you will be weak and sickly at best, and die at worst!

As for him, Kujo Tachibana, it can be said that he is currently in a state of frailty and illness, and is on the verge of death.

He chose to practice Tai Chi simply to move his body as much as possible and slow down the deterioration of his physical fitness.

...

That evening, Jiujiao Ju, as usual, slowly performed a set of "health-preserving boxing" under the ginkgo tree in the courtyard.

But I have to say that Tai Chi does have some effect.

Because Kujo Tachibana is now able to observe subtle changes in his body, he is particularly sensitive to the effects of Tai Chi.

Now he not only practices by himself, but also pulls Ubuyashiki Yoshiya, the real "sickly guy", to practice together every morning.

The hot weather during the day began to become comfortable as the sun slowly set.

The evening breeze brought a hint of coolness, blowing on the boy's sweaty body. Kujo Ju couldn't help but moan in comfort.

After taking off his wet coat, Jiujo Ju came to the well in the yard, scooped up a bucket of well water, and was about to wash clothes when he discovered...

At this time, an earthworm was moving on the edge of the well.

"Little guy, you can't swim. This is not the place for you to play."

Jiujiaoju picked up the earthworm beside the well and was about to throw it on the soil beside it.

At this moment, the slippery feel of the earthworm suddenly gave Jiujo Ju a flash of inspiration!

Jiujo Ju retracted his palm and looked at the earthworm quietly as it rolled in his palm.

Jiujiaoju is no stranger to animals called earthworms.

There was a time in his previous life when he loved fishing and was very familiar with this kind of "bait".

Earthworms have a very strong attraction to some carnivorous fish and omnivorous fish.

Such as crucian carp, catfish, black carp, snakehead fish, carp, tilapia, etc...

Uh, that’s off topic, let’s get back to the point.

And the earthworm’s unique way of breathing!

It also reminded Jiujo Ju!

Why do we have to use our lungs to breathe?

You should know that earthworms also need to breathe, but they don’t have lungs because they can breathe directly through their skin!

What about humans? Can they breathe through their skin and pores?

In this world, no one can give Jiujo Tachibana an answer.

...

In fact, what Kujo Tachibana was thinking was not wrong.

The pores on human skin can actually breathe!

The human body can not only excrete toxic substances through its pores, but also achieve self-purification.

The amount of oxygen absorbed through the human skin within 24 hours every day is about three to four grams.

This quantity is also related to temperature.

At thirty degrees Celsius, human skin respiration accounts for one percent of total gas exchange.

In a high temperature environment, the gas metabolism of the skin accounts for about 15 to 20 percent of the gas metabolism of the lungs.

And this happens automatically by the pores of some bodies without human consciousness or control, simply due to stimulation from the external environment.

So how many pores are there on the human body?

The answer is! Millions, depending on the person.

If someone could control the pores all over his body, could he abandon his lungs and breathe entirely through his pores?

-

Looking at the earthworm in his palm, Jiu Tiao Ju closed his eyes and began to search in his mind for the relevant memories of Blue Star in his previous life, such as key words such as body respiration and pore respiration.

After a moment, Jiujo Ju slowly opened his eyes, and those eyes were so bright!

Looking at the earthworm in the center of his palm, Jiu Tiao Ju patiently found a moist soil in the yard, put the earthworm down, and whispered softly:

"We all have a bright future ahead of us."

-

Yes, Jiujo Tachibana found some relevant information in his memory!

He is now full of confidence in the path of walking breathing!

...

In his previous life on Blue Star, Jiujo Ju once browsed a post on the Internet about the realm of ancient warriors.

Of course, these were all posted on the Internet by modern people. Kujo Tachibana had no way of verifying whether they were true or not at the time, and he just treated them as an interesting story.

According to this post, when ancient warriors trained their internal energy to the level of a first-rate master and opened up their meridians, they would reach a state called the innate state.

After reaching this state, not only can one strengthen the five internal organs, but one can also control the opening and closing of every inch of the body's epidermal pores through mental strength, achieving the effect of body breathing.

In modern times, roughly during the late Qing Dynasty and the Republic of China, martial artists focused more on practicing boxing because of the massive loss of internal strength caused by war.

Boxing is divided into internal boxing and external boxing. Martial artists who practice internal boxing will improve their boxing skills to a very high level.

It will also reach a state similar to body breathing. The warriors at that time called it breaking the void and seeing the indestructible gods.

Warriors who have reached this realm can not only rely completely on the pores on their body surface to breathe.

You can even control your own body hair, allowing it to grow and fall freely.

In addition, there are some legends about the Taoist masters of China.

According to rumors, Taoist masters who have practiced Taoism to a certain level can also reach a state similar to that of warriors' breathing.

All of this told Kujo Tachibana that it was entirely possible to use pores for body breathing!

-

Has anyone thought of this? There is a data about pore breathing in the middle. I didn’t make it up. It’s all information I found on the Internet.

Chapter 39 Body Breathing

Why, over thousands of years, these groups of people have no connection with each other and have completely different power systems?

Will both produce a similar result?

There are three thousand great ways, all leading to the same destination!

Just because these people, in essence, are moving towards the path of life evolution.

-

"The sense organs can control muscles and blood vessels, but what about pores?"

"It should be controllable, right?"

Kujo Tachibana muttered to himself.

You should know that there are six billion muscle fibers in the human body, and the number of blood vessels is even more exaggerated.

Two hundred and fifty trillion!

The total length connected together is 150,000 kilometers!

Of course, most of them are capillaries.

Some of the capillaries in the human body are much smaller than pores and cannot be seen with normal vision.

Since he can control such thin blood vessels, there is no reason why he can't control the pores, right?

Thinking of this, Kujo Tachibana concentrated his mind and began to experiment on his own body.

Sensing the countless tiny holes all over the body, which were densely packed and had never been noticed before.

Jiujo Tachibana tried to slowly control the pores on his arms, opening and contracting them...

After all, it was the first time for Kujo Tachibana to control pores, so he was still a little unfamiliar with it.

The operation is inevitably slow and cumbersome, but with the passage of time.

With Kujo Tachibana's powerful mental strength, he was able to control the pores on his arms more and more easily.

The air quickly entered Kujo Tachibana's body as the pores on his arms opened.

After a while, Jiujiaoju felt a slight coolness on his arm.

The process went smoothly. It was not difficult for Kujo Tachibana to control the opening and closing of the pores using his sensory mind.

Jiujo Tachibana's eyes lit up.

He felt it! His body was indeed breathing!

Breathing is done without relying on the lungs, only through the pores!

This long-lost feeling of satisfaction filled Kujo Tachibana's whole body.

...

Suddenly, as if he had thought of something, Kujo Tachibana's pupils shrank sharply and he looked at his arm in astonishment.

You know, he has just controlled the breathing of the pores on one arm!

And this one arm is equivalent to 80% of the breathing effect when it was in its previous prime and the lungs were intact!

If he could control all the pores in his body and breathe, how amazing it would be!

Then, if he breathes once through all the pores in his body, wouldn't it be equivalent to breathing dozens of times with his lungs?

Jiujo Ju hurriedly breathed a few more times through the pores on his arms, and only then did he calm down his excitement.

After slowing down, Kujo Tachibana found that he seemed to be happy too early.
