Ghost Slayer Headquarters, Butterfly House.

Chijuro lay on his back on a wicker chair with an expression of enjoyment on his face.

In front of him, in the courtyard of the butterfly house, Tanjiro, Inosuke, and my wife Zenyi were humming and doing swordsmanship training.

It's been three days since the Battle of the Infinite Train.

After settling the injured passengers, Chijuro returned to the headquarters with the injured Kyojurou and reported the mission to the lord.

After learning that the second of the upper strings, Tong Mo and the third of the upper strings, and one of the lower strings as an additive, Nightmare Yume, died at the hands of Senjuro, Yaoyashiki, who was sick in bed, was so excited that he sat up on the spot.

After some inquiry, amid his chattering "hope, hope", Senjuro and Kyojuro temporarily stepped back and came to the butterfly house for recuperation.

It's said to be recuperation.,In fact, the only people who need treatment are Kyojuro and Tanjiro.,Although Senjuro was a little anxious during the whole mission against Tong Mo.,But he didn't suffer any injuries during the whole process.。

But.

Who said you can't come to Butterfly House .jpg if you're not injured?

The environment here is beautiful, the air is fresh, the birds are singing and the flowers are fragrant, and the flowers are full of flowers...... Ahem, it's a bit hard to make it up.

Well, Senjuro admits that in fact, these are just incidental.

He came here just to accompany the injured Kyojuro, and it definitely has nothing to do with Butterfly Shinobi.

Speaking of this black-bellied woman, she has disappeared since the last trial of the Zhuzhong, and it is said that she went to discuss some pharmacological knowledge with Miss Zhu Shi, who was visited by the lord at the beginning.

As for the location, because he had promised Miss Zhushi to keep it secret, Yaoya Sanyashiki could only shake his head with a wry smile and apologize to Senjuro who asked.

Not being able to get accurate information made Senjuro a little disappointed, but it didn't matter. Counting the time, it's almost time for the butterfly shinobi to return.

Nothing to do, butterfly ninja is not there, in addition to daily exercise, the only fun of Chijuro is to train and train the three of Tanjiro.

The Infinite Train's astonishing record of killing the three Twelve Ghost Moons made Tanjiro and the three of them admire Senjuro very much, and after experiencing the battle with one of the lower strings, Nightmare, the three of them deeply understood how terrible the Twelve Ghost Moons were, not to mention the two winding ghosts ranked much higher than Nightmare.

Unlike Tanjiro, who faced the Uzuza directly, Inosuke, who woke up from a coma, felt the aftermath of the battle between the upper winds and the pillars, and his body trembled with instinctive fear.

Therefore, when Inosuke, who has a straightforward personality, sees Senjuro in Butterfly House, he wants to worship the mountain head and recognize him as the boss on the spot, and Tanjiro and my wife Zenyi, who are very excited to see this, also follow suit and say that they should do the same.

Chijuro, who couldn't cry or laugh, stopped the three of them.

He still has some good feelings about this wild boar boy whose behavior is a little weird compared to ordinary people, and in the battle of the infinite train, this boy and Tanjiro do their best to protect the sleeping passengers.

In the case that Chijuro and Kyojuro were both dragged by the winding, if it weren't for the two of them, it would be really ignorant that the entire train would survive in the end.

Although he rejected the behavior of the three people to recognize the boss, out of appreciation for them, Senjuro said that he would guide them for a period of time in the butterfly house.

Knowing the strong strength of Qianjulang, they were overjoyed when they heard this promise.

After seeing the monster in the Twelve Ghost Moons, the three of them realized the weakness of their strength, the kind of life and death that are not controlled by themselves, as if they will become powder if they are pinched by others at will, it is difficult for those who have not experienced it to understand.

After this battle, even Shanyi, who was afraid of war, began to actively exercise himself.

And being able to learn from such a powerful pillar as Lord Firepillar is naturally a very valuable opportunity.

Therefore, during the few days of recuperation in Butterfly House, every evening, the three of them would be in the Butterfly House courtyard and listen to Senjuro's teachings.

And [Breath of Fire] reached the grandmaster level of Qianjulang, who can almost be said to be the swordsman with the highest swordsmanship attainment in the Ghost Slayer Team today.

Although the breathing method he learned was different from the three of them, he was able to accurately point out the flaws in the swordsmanship of the three of them.

Through continuous improvement and perfection, the level of swordsmanship of the three of them during this period can be said to have made great progress.

Tanjiro, in particular, is particularly prominent.

In a battle with Inosuke, he uses a breathing method that is completely different from the breath of water.

Its nature exploded like fire, but it contained a majestic atmosphere like the scorching sun, and its power was so incredible that it made Chijuro, who was watching the battle and preparing for guidance, be greatly shocked.

Unlike Inosuke and Zenitsu, who didn't have enough vision and were only amazed when they saw the "God of Fire Kagura", Senjuro, who had reached the realm of a grandmaster in swordsmanship, could clearly feel that the strange breathing method used by Tanjiro had a fundamental connection with all the breathing techniques he had ever seen.

It is as if it is the source of the five basic schools of breathing that are circulating today.

This made Chijurou rub his chin and think for a moment.

He remembered what the Upper Breath System of Fire had introduced to him.

"[Breath of Fire] (Grandmaster): One of the five basic breathing schools derived from the breath of the sun, it is a breathing method passed down from generation to generation by the Purgatory family, and its attack power is very powerful......"

"Breath of the Sun......

For this set of root breathing methods derived from the five basic schools of breathing, Senjuro is still very interested.

There are not many references to the Breath of the Sun in the surviving texts of the Demon Slayer Squad.

I only know that it is a powerful breathing method created by an original breathing swordsman named "Jikoku Yuanyi".

However, for unknown reasons, the Ghost Slayer's inheritance of the Breath of the Sun has been completely broken, and there is no way to practice the Breath of the Sun.

And this strange and unusually powerful breathing method used by Tanjiro has a high probability that it is this long-lost root breathing method.

However, after trying to get Tanjiro to teach him "Kagura, the god of fire", Chijurou reluctantly gave up his plan to learn "Breath of the Sun".

"Taught by Tanjiro Kamado, do you learn the skill [Breath of the Sun]?"

"Please note! Please note! Please note! Due to the large difference in physique, learning this skill has a high probability of causing the collapse of the body, do you want to learn? ”

Seeing the prompt, Chijuro's face darkened.

It is said that there is a high probability that the body will collapse, so what to learn.

He didn't want to use the power of the system to forcibly control the breath of the sun, and after that, his flesh exploded with a "bang".
