Learned [Sun Breathing - First Form - Waltz]!

Learned [Sun Breathing - Second Form - Azure Heaven]!

……

……

Learned [Sun Breathing - Twelfth Form - Flame Dance]!

A long list of skills is displayed on Suoh Takeru's adventurer card, a dense and dizzying array.

Sun Breathing Technique Acquired, da☆ze~

We made a profit! We made a profit!

Suoh Takeshi suppressed his inner excitement, and although he remained calm on the surface, a satisfied smile involuntarily crept onto his lips.

As luck would have it, Shinobu Kocho discovered it.

"Suoh-kun seems to be in a good mood. Is it because he learned the Sun Breathing Technique?"

"Sigh, isn't that a rhetorical question?"

Suoh Takeshi blinked, but didn't deny it.

"It still seems unbelievable that someone could learn something after just one viewing..."

Shinobu Kocho didn't believe what Suoh Takeshi said at first, but Suoh Takeshi's dance just now proved that what he said was true.

She had no choice but to believe it.

"It's just that we've taken the lead. There's no need to be discouraged. We're comrades, aren't we?"

"Hehe, Suoh-kun is right, we are comrades."

Butterfly smiled broadly.

After practicing, Tokito Muichiro's aura remained unchanged, except that the small wooden stick in his hand had burned out completely.

"This is the Sun Breathing Technique."

He looked at everyone and said calmly, "However, I do not recommend that you learn this."

"..."

"—Why?!?" xN

The shouts of the crowd pierced the sky.

"Through practicing the Sun Breathing Technique, I came to understand a principle: the realm of martial arts, though different, leads to the same goal."

Tokito Muichiro stared blankly at the sky.

"It is not the breathing technique of the sun that is powerful, but the person who uses the breathing technique. If you rashly learn a breathing technique that is incompatible with your own, your strength will drop sharply."

Muichiro Tokito truly lives up to his reputation as a genius!

This level of understanding is truly admirable!

Yoriichi Tsugikuni once said, "Those who explore the path to its end will all find the same destination."

Presumably, Muichiro Tokito also discovered the truth behind it.

Although Sun Breathing is the starting breathing method, it is actually no different from other derivative breathing methods except that it has properties similar to the sun.

The Sun Breathing Technique has a special effect on Muzan Kibutsuji, and because the user is Yoriichi Tsugikuni, a top-tier figure, it appears exceptionally powerful, so powerful that Muzan Kibutsuji was so afraid that he hid for over a hundred years!

But you need to understand.

It was Yoriichi Tsugikuni who unlocked the Mark and the Transparent World, not just anyone who learned the Breathing of the Sun technique who became that strong!

Otherwise, wouldn't Tanjiro Kamado have become stronger than the Pillars in no time?

In contrast, for some of the pillars who learn derivative breathing techniques, it becomes especially important to adapt them to their own characteristics.

Abruptly changing their breathing techniques would only cause their strength to regress, leading to stagnation.

"What do you mean? You're not going to learn anymore?!"

Sanemi Shinazugawa disliked Muichiro Tokito's indecisive manner of speaking. "If we don't learn the Sun Breathing Technique, how will we fight Muzan Kibutsuji?!"

"..." The pillars remained silent.

"Learn from others' strengths and make up for your own weaknesses, and refine your breathing techniques."

Suoh Takeshi came out.

"Ultimately, the power of the Sun Breathing Technique lies in its resemblance to the sun. So why don't we think about it the other way around and incorporate this characteristic into our own breathing technique?"

"Hmm...that makes sense."

The Rock Pillar, Himeyasu Gyomei, seems to agree with this view.

"I feel that I have a good synergy with the Sun Breathing Technique, and I want to give it a try!" Rengoku Kyojuro looked at Tokito Muichiro with enthusiasm in his eyes.

"Do as you please. I'm just letting you know."

Tokito Muichiro looked indifferent and didn't try to persuade him further.

He doesn't intend to learn the Sun Breathing Technique; instead, he wants to integrate it into the Mist Breathing Technique to refine his skills and reach a higher level!

"Um... I'd like to try it too."

Kanroji Mitsuri whispered, "My swordsmanship is more like gymnastics and dance, and it's similar to Kagura dance. We should have some things in common."

Her Love Breathing Technique is a derivative of the Fire attribute breathing technique, and her Sun Breathing Technique has also been modified into Kagura's dance, so she felt she could give it a try.

The rest of the people refused.

"Well, I'll pass!"

Uzui Tengen said loudly, "Although my Sound Breathing Technique is not as flashy as the Sun Breathing Technique, it is the most suitable derivative breathing technique for me and it also fits my ninja way, so I'd better not change it."

"Unfortunately, I don't have much stamina, so I can't learn the Sun Breathing Technique." Shinobu Kocho also refused.

"Me too."

"And me too."

"..."

In the end, apart from Flame Pillar Kyojuro Rengoku and Love Pillar Mitsuri Kanroji, all the other Pillars gave up.

To Suoh Takeshi's surprise, even Sanemi Shinazugawa, the Wind Pillar who had been clamoring to learn, gave up.

It seems he took what Suoh Takeshi said to heart.

"Then, let's begin the guidance on the practice!"

Suoh Takeshi suggested:

"Guiding your training is not only about guiding you in learning the Sun Breathing Technique, but also about you guiding Tanjiro and the others in their training, and at the same time, teaching me the breathing techniques you possess."

Three birds with one stone!

"So, what do you think of this suggestion?"

Suoh Takeshi's words surprised everyone slightly.

"Well, isn't this a good thing? We should also mentor the younger generation."

Kyojuro Rengoku laughed loudly, "I was complaining to the lord last night that the Demon Slayer Corps' quality has been too low lately. Since that's the case, let's take this opportunity to give them a good workout!"

"I agree. This magnificent ninja will show them just how magnificent a being can be."

"I second that."

"Alright."

Suoh Takeshi's proposal was approved by the other pillars.

As it grew late, everyone left, preparing to resume the next day.

The Demon Slayer Corps began its training.

It wasn't just Tanjiro Kamado, Zenitsu Agatsuma, Inosuke Hashibira, and Kanao Tsuyuri; training began on all swordsmen of every rank in the Demon Slayer Corps.

But the purpose is not limited to that.

One aspect was to train and hone their own strength, while another was to select Demon Slayer Corps swordsmen who could practice the Sun Breathing technique.

After all, how to integrate the solar characteristics of the Sun Breathing Technique into one's own breathing technique is still an unsolved mystery and remains to be discussed.

Just in case, the Demon Slayer Corps is making two preparations.

The Sun Breathing Technique also requires someone to train with, so the Demon Slayer Corps began recruiting qualified members.

Time flies.

A week has passed in the blink of an eye.

In the open space behind the Demon Slayer Corps mountain.

Suo Takeshi and Tomioka Giyuu stood facing each other and shouted at the same time:

"Water Breathing - Type 11 - Calm and Tranquil".

"Water Breathing - Type 11 - Calm and Tranquil!"

Huge ripples spread out from beneath their feet, and two giant waves began to collide and then subside, collided again and subsided once more.

This is a seemingly slow but actually very fast domain-type sword technique, a defensive divine skill that can nullify all attacks!

However, the two used the exact same sword technique, and neither could defeat the other.

"..."

"..."

After a long stalemate, Giyu Tomioka finally spoke up: "Martial arts, you can learn any sword technique after just one look. This talent is truly enviable."

"Giyong is not bad either; he actually managed to develop such a powerful sword technique on his own. However..."

Suoh Takeshi also praised him, then lowered his body and spoke to him.

"Yiyong, this next move is a technique I adapted by combining the Water Breathing method with other sword techniques. Please give me your guidance!"
