Emiya saw something very interesting among these medical books.

For example, more than 400 years ago, when Guoyuanyi was not born, the ghost killing team at that time did not know how to breathe, and their battle with ghosts occupied an overwhelming disadvantage.

In that era, an ordinary ghost could kill several swordsmen of the ghost killing team.

At that time, the swordsmen in the ghost killing team used their lives to fill in the number of people.

Basically, after encountering a ghost, several swordsmen, or even a dozen swordsmen from the ghost killing team, will all be dispatched to encircle and suppress. Every time a ghost is killed, several companions will die.

In that era, there was no doubt that ghosts were powerful.

However, the members of the Demon Slayer Team are not bad at wisdom. After realizing the power of ghosts, they began to study ghosts, and many people even put forward a crazy idea.

Use ghosts to control ghosts.

To put it bluntly, it is to take the initiative to accept the blood of the ghost, turn yourself into ghosts, and exchange them for powerful power to deal with ghosts.

So the ghost killing team at that time dispatched many people, caught a few ghosts, used the medical skills at that time to study ghosts, and even transformed their own people to adapt to ghosts' blood and ghost abilities.

But the result is very simple and it failed.

The blood of ghosts is strongly corrosive. After receiving the blood of ghosts, humans quickly fall into depravity and eventually become new ghosts.

Of course, there are also some people who are born with a certain degree of resistance to the blood of ghosts. After receiving the blood of ghosts, they can maintain themselves for a period of time and their strength will greatly increase.

This is a bit similar to the current brother of Fukumatsu Mudhikawa Miya... Fukumaki Genya.

Immortal Kawa Kyama is such a person who has excellent biting and digestive organs and has a special physique that can eat ghosts. With this short-term ghost transformation, the stronger the ghosts they eat, the more they gain the regeneration ability and power of ghosts they gain.

But now it seems that Immortal Kawa Kinya was very outstanding among those people at that time.

Anyway, it was a very difficult era.

In order to fight against ghosts, the members of the Ghost Kill Team took the initiative to accept ghost blood and jumped back and forth on the brink of depravity and madness. At that time, the Ghost Kill Team also developed many drugs that can suppress ghost blood.

If this path can continue, with the development of medical skills, the Demon Killing Team may really use medicine to complete the devil transformation, ultimately maintaining its own rationality and enhancing its strength.

However, at this moment, the walls of this world were born.

Follow the country's fate.

A guy who is born with breathing and enlightenment of the world can make mortals despair with just a little effort. When others develop marks and live to be twenty-five, the other person can live to be over 80 years old.

His appearance was like a ray of light, illuminating the entire ghost killing team.

So the members of the Demon Slayer team abandoned the path of drugs to suppress ghost blood, learned breathing, and with excellent swordsmanship, they once gained an absolute advantage in the battle with ghosts.

Even Muzan Kitsuki almost died at the hands of Jiko Minichi, let alone other ghosts.

After all, Muzan Kimuzan had not yet formed the Twelve Ghost Moon at that time.

Muzan Kimuzan was pressed to the ground by Kyoto Kiyoshi and rubbed it. After running away by chance, he shrank, while the other ghosts lost his leader and were defeated by the members of the Demon Slayer Team.

The ghosts at that time were once destroyed.

But unfortunately, Ji Guoyuanchi finally let Muzan run away.

This guy waited until after Guoyuan Yi's death, he ran out to stir up the wind and rain. He established the Twelve Ghost Months and killed a large number of swordsmen in the Ghost Slaying Team, resulting in the loss of the method of opening the marks.

And this situation continues to this day.

Emiya looked through the past medical skills and various records, and couldn't help but shake her head, using drugs to suppress ghost blood, and possessing the ability of ghosts. Although this path is full of blood and tears, the effect is really there.

Unfortunately, when the road was halfway through, or even less than half, Guoyuan emerged and cut off this road.

This made Emiya a little regretful.

If Ji Guoyuanyi did not appear, the current ghost killing team might be a different scene.

These studies seem amazing, but in the end it is an unready path and has no use for the Ushi.

Emiya didn't study it carefully, just regarded it as a fun.

However, breathing techniques and swordsmanship made Emiya refreshed and felt a little rewarding.

Four hundred years ago, after Kyotoichi founded Rizhi Breathing, but unfortunately, no one except Tanjiro, the ancestor of Zaomen, learned this breathing method.

Later, the swordsmen of the Demon Slayers derived five basic breathing methods based on the breath of Sun... Flame, Water, Wind, Rock, and Thunder.

But these breathing methods are not suitable for everyone.

Many people have created their own breathing methods based on their breathing habits and using these five basic breathing methods.

For example, the breath of insects by Butterfly Ninja, the breath of flower by Her dead sister Butterfly Kanae. The breath of the sound of the sound of the sound of the sound of the sound of the sound of the love of the love of the love of the gust, the breath of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust of the gust

After these people create their own breathing method, they will leave a portion of the breathing method in the Paiyashi family, fearing that the breathing method will be lost after their death.

In the past four hundred years, many pillars also created their own breathing methods. Some were lost with the death of the pillar, but some copies were copied and left in the Saiyashiki clan.

And these were given to Emiya by Shikiya Shikiya.

So this time Emiya obtained nearly a hundred completely different breathing techniques and supporting swordsmanship.

Of course, there are also some sword techniques before the breathing technique was born.

At first, Emiya did not like these breathing methods. He only valued one breathing method, that is, the breathing method, which is the God of Fire mastered by Tanjiro Kazuno.

However, when Emiya came into contact with these messy breathing methods, he was surprised to find that there were indeed some extraordinary things in these breathing methods.

It's not as useless as I imagined.

Although all these breathing methods are derived from the breath of the sun, after years of development, in addition to the five basic breathing methods and some characteristics of the breath of the sun, the other breathing methods are the shadow of the breath of the sun.

In other words, these breathing methods, such as the breathing of snakes, the breathing of clouds, and the breathing of flowers, basically have little to do with the breathing of suns, but they each have their own advantages.

As for why Emiya understood so much, of course it was because he had learned to breathe in Hiroshi.

In fact, as early as the Fujishiyama selection was over, Emiya took Tanjiro Satomi back to Nagiriyama to find his master, Tanjiro Satomiya performed the breathing of Hiroshi, which is the God of Fire, in front of Emiya.

Emiya remembered this breathing method at that time.

If it were the past, Emiya might not have been able to do this.

But since I learned to chant, my physical fitness improved rapidly, and my brain's mental strength soared, Emiya's speed of learning things became faster and faster.

Emiya learned a set of breathing methods after reading them almost once.

No effort.

In Emiya's view, the most amazing thing about Hina's breathing is not its attack power. In fact, other breathing methods, including Hina's breathing, can increase the strength of ordinary people.

But this kind of improvement is nothing to Emiya's opinion.

What really surprised Emiya was that Hiroyuki's breathing had some very powerful effects on physical strength recovery.

For example, in the plot, Tanjiro Zaomen's father once told him that if the dance of the God of Fire is correct, it can keep dancing.

When Tanjuro Sagamen danced Kagura dance, he was usually weak and sick, even if he danced for a day and a night in the heavy snow, he would not feel so tired.

This is enough to prove the power of the God of Fire, which is the breath of the sun.

As long as you breathe correctly, your physical strength can be recovered quickly, and even weak people can jump for a day and a night.

Although the breathing methods of other schools also have the characteristics of extending physical strength and quickly restoring physical strength, compared with Rizhi's breathing, it is a slight witch.

But it is undeniable that other schools of breathing also have their own characteristics.

For example, the characteristic of Rock's breathing is its strength.

As long as you learn this breathing method, you can wield heavy weapons to fight. The strength of each strike is extremely heavy, enough to easily destroy the ground.

Thunder Breathing is the fastest and most explosive of all breathing. It has extremely high requirements for the user's physical fitness, so it is extremely difficult to practice.

The move is very fast, and the super-high-speed assault will even produce thunder roaring around.

When Emiya saw so many breathing methods, a thought suddenly came to his mind.

If we use the breathing of the sun as the origin and integrate so many breathing characteristics into one, can we create a breathing method that exceeds the breathing of the sun?

It can even be combined with thoughts to improve combat effectiveness.

This is not Emiya's whimsical idea.

The main reason is that Emiya knows that the upper limit of breathing method is not low. For example, Emiya knows that a breathing method is perverted, and can even be said to be a breathing method with extraordinary power.

That is...ripples breathing in the wonderful adventure story of jojo!

Or it is called ripple Qigong.

Rippled breathing not only has the same effect as sunlight, but also allows ordinary human bodies to produce great power in an instant, and can also achieve various effects through subtle control.

Moreover, those who practice can strengthen their bodies and resist aging in different ways.

Even healing the human body and the dead trees can be done in spring.

Since Rippled Breathing can do this, there is no reason why the breathing method of Demon Slayer Blade World cannot do this.

The reason why it cannot be done is probably because it has not been created yet.
