Volume 5: Demon Slayer Chapter 015 Imagination
Emiya saw some very interesting things in these medical books.
For example, more than four hundred years ago, when the great master Yoshiichi Tsugukuni was not yet born, the Demon Slayer Corps did not know how to breathe, and they were at an overwhelming disadvantage in their battles with the demons.
In that era, any ordinary demon could kill several swordsmen of the Demon Slayer Corps.
At that time, the swordsmen of the Demon Slayer Corps killed demons entirely by relying on numbers and sacrificing their lives.
Basically, when encountering a demon, several swordsmen, or even more than a dozen swordsmen from the Demon Slayer Corps, would go out together to encircle and suppress it. Every time they killed a demon, several companions would die.
In that era, the power of ghosts was unquestionable.
However, the members of the Demon Slayer Corps are also quite smart. After realizing how powerful demons are, they began to study them, and many of them even came up with crazy ideas.
Use ghosts to control ghosts.
To put it simply, it means actively accepting the blood of ghosts, turning yourself into a ghost, and gaining powerful strength to deal with ghosts.
So the Demon Slayer Corps at that time mobilized a lot of people, captured several demons, used the medical skills of the time to study the demons, and even transformed their own people to adapt to the demons' blood and abilities.
But the result was simple, failure.
The blood of ghosts is highly corrosive. After humans absorb the blood of ghosts, they quickly degenerate and eventually become new ghosts.
Of course, there are also some people who are born with a certain resistance to ghost blood. After accepting ghost blood, they can maintain their self-identity for a period of time and their strength will be greatly increased.
This is somewhat similar to the younger brother of the current Wind Pillar Fushigawa Jyouya... Fushigawa Genya.
Fushigawa Genya is such a person. He possesses excellent bite force and digestive organs, and has a special physique that allows him to eat ghosts and thus become a ghost for a short period of time. The stronger the ghost he eats, the more the regenerative ability and strength of the obtained ghost will be enhanced.
But now it seems that Fushigawa Genya can be said to be very outstanding among those people back then.
Anyway, it was a pretty difficult time.
In order to fight against demons, members of the Demon Slayer Corps took the initiative to accept demon blood, and repeatedly jumped back and forth on the edge of depravity and madness. At that time, the Demon Slayer Corps also developed a number of drugs that could suppress demon blood.
If they can continue on this path, with the development of medical technology, perhaps the Demon Slayer Corps can really use drugs to complete the transformation into demons, and ultimately maintain their sanity and enhance their strength.
However, at this moment, the hanging wall of this world was born.
Tsugikoku Yoshiichi.
He was born with the ability to breathe and see through the world. With just a little effort, he could make mortals despair. While other people would not live past the age of 25 after developing the markings, he could live to over 80 years old.
His appearance was like a ray of light, illuminating the entire Demon Slayer Corps.
So the members of the Demon Slayer Corps abandoned the way of suppressing demon blood with drugs, learned breathing techniques, and with their excellent swordsmanship, they once had an absolute upper hand in the battle with demons.
Even a guy like Muzan Kibutsuji almost died at the hands of Yoriichi Tsugakuni, not to mention other demons.
After all, at that time, Muzan Kibutsuji had not yet formed the Twelve Kizuki.
After being pinned to the ground by Yoriichi Tsugakuni, Muzan Kibutsuji managed to escape and then hid away. The other demons, after losing their leader, were defeated one by one by the members of the Demon Slayer Corps.
The ghosts at that time disappeared for a time.
But unfortunately, Tsugumi Yoshiichi eventually let Muzan Kibutsuji escape.
This guy waited until Tsugumi Yoshiichi died of old age before coming out to stir up trouble, establishing the Twelve Kizuki, and killing a large number of swordsmen of the Demon Slayer Corps, causing the method of opening the markings to be lost.
And this situation continues to this day.
Emiya flipped through the medical skills and various records of the past and couldn't help but shook his head. Although the path of using drugs to suppress demon blood and possessing demon abilities was full of blood and tears, it was indeed effective.
Unfortunately, when this road was halfway through, or even less than halfway through, Jiguo Yuanyi suddenly appeared and cut off this road.
This was a bit of a pity for Emiya.
If Yoichiro Tsugakuni had not appeared, the Demon Slayer Corps might be in a different situation now.
These studies seem amazing, but they are ultimately a dead end and are of no use to Emiya.
Emiya didn't study it carefully, he just watched it for fun.
However, the breathing techniques and swordsmanship were refreshing to Emiya and he felt he had gained something.
Four hundred years ago, Yoshiichi Tsugumi created the Sun Breathing, but unfortunately, no one except Tanjiro Kamado's ancestor has learned this breathing method.
Later, the Demon Slayer Corps swordsmen derived five basic breathing methods based on the Sun Breathing...fire, water, wind, rock, and thunder.
But these breathing techniques are not suitable for everyone.
Many people have created their own breathing methods based on these five basic breathing methods according to their own breathing habits.
For example, there is the Insect Breathing of Shinobu Kocho, the Flower Breathing of her deceased sister Kanae Kocho, the Sound Breathing of Uzui Tengen, the Love Breathing of the Love Pillar, the Mist Breathing of the Mist Pillar, the Snake Breathing of the Snake Pillar, and so on.
After these people created their own breathing method, they would leave a copy with the Ubuyashiki clan, fearing that the breathing method would be lost after their death.
In the four hundred years before them, many pillars also created their own breathing methods. Some of them were lost with the deaths of the pillars, but some were copied and left in the Ubuyashiki clan.
And these were given to Emiya by Ubuyashiki Yoya.
So this time, Emiya acquired nearly a hundred completely different breathing methods, as well as matching sword techniques.
Of course, there are also some sword techniques that existed before the breathing method was invented.
At first, Emiya did not like these breathing methods. The only breathing method that mattered to him was the Sun Breathing, which is the Fire God Kagura mastered by Tanjiro Kamado.
However, when Shirou came into contact with these messy breathing methods, he was surprised to find that there were indeed some extraordinary aspects in these breathing methods.
It's not as useless as I imagined.
Although all these breathing methods are derived from Sun Breathing, after years of development, except for the five basic breathing methods and some characteristics of Sun Breathing, the other breathing methods are only left with the shadow of Sun Breathing.
In other words, these breathing methods, such as Snake Breathing, Mist Breathing, and Flower Breathing, basically have little to do with Sun Breathing, but each has its own merits.
As for why Emiya understood it so well, it was of course because he had learned the Breathing of the Sun.
In fact, as early as the end of the Fujisakayama selection , when Emiya took Tanjiro Kamado back to Sagiri Mountain to find his master, Tanjiro Kamado performed the Breathing of the Sun, also known as the Fire God Kagura, in front of Emiya.
Emiya memorized this breathing method at that moment.
If it were in the past, Emiya might not have been able to do this.
But ever since he learned Nen, his physical fitness has improved rapidly, his brain's mental power has skyrocketed, and Emiya's learning speed has become faster and faster.
A set of breathing techniques that Shirou learned almost immediately after watching it once.
No effort required.
In Emiya's opinion, the most amazing thing about Sun Breathing is not its attack power. In fact, other breathing methods, including Sun Breathing, can improve the strength of ordinary people.
But in Emiya's opinion, this kind of improvement is nothing.
What really surprised Emiya was that Sun Breathing had a very powerful effect on restoring physical strength.
For example, in the plot, Tanjiro Kamado's father once told him that if he breathes in the correct way to dance the Fire God Kagura, he can keep dancing.
And when Tanjuro Kamado performed the Kagura dance, he, who was usually weak and sickly, would not feel very tired even if he danced for a whole day and night in the snow.
This alone is enough to prove the power of Kagura, the God of Fire, also known as Breathing of the Sun.
As long as the breathing is correct, physical strength can be restored quickly, and even a weak person can jump for a whole day and night.
Although other schools of breathing techniques also have the characteristics of prolonging physical strength and quickly recovering physical strength, they are nothing compared to the Sun Breathing.
But it is undeniable that other schools of breathing techniques also have their own characteristics.
For example, the characteristic of Rock Breathing is its great power.
As long as you learn this breathing method, you can wield heavy weapons to fight, and the power of each blow will be extremely heavy, enough to easily destroy the ground.
The Breathing of Thunder is the fastest and most explosive of all breathing techniques. It requires extremely high physical fitness from the user, and is therefore extremely difficult to practice.
The speed of the attack is very fast, and the ultra-high-speed attack will even produce thunderous sounds around.
When Emiya saw so many breathing methods, an idea suddenly popped up in his mind.
If we take Sun Breathing as the origin and integrate the characteristics of so many breathing methods into one, is it possible to create a breathing method that surpasses Sun Breathing?
It can even be combined with thoughts to enhance combat effectiveness.
This is not just a fantasy on the part of Emiya.
This is mainly because Emiya knows that the upper limit of the breathing method is not low. For example, Emiya knows a breathing method that can be called perverted and even can be said to have extraordinary power.
That is the ripple breathing in JOJO's Bizarre Adventure!
Or it can be called Ripple Qigong.
Ripple breathing not only has the same effect as sunlight, but can also allow ordinary people to generate tremendous power in an instant, and can also achieve a variety of different effects through subtle control.
Moreover, those who practice can strengthen their bodies and resist aging in different ways.
It can even heal the human body and bring dead trees back to life.
Since the ripple breathing can do this, there is no reason why the breathing method in the Demon Slayer world cannot do this.
The reason why it cannot be done is probably because it has not been created yet.
If someone is willing to work hard on this, maybe they can really create a breathing method that surpasses the Sun Breathing and is not inferior to the Ripple Breathing.
