Demon Slayer: I am a Demon.

"Although I don't know what the gentleman did to offend Miss Shinobu, please don't take it to heart. The gentleman is a very good person, and he didn't do it on purpose."

"I...didn't take it to heart."

Shinobu took another sip of porridge and immediately replied.

"If that's the case, that would be wonderful."

Nezuko looked somewhat excited, then couldn't help but whisper, "Sir is such a kind person. If I have done anything to upset Miss Shinobu, please don't blame him..."

Shinobu Kocho didn't reply, but just silently drank her porridge. Nezuko, however, continued to chatter on and on, her words inadvertently touching on Su Mu.

Kocho couldn't help but glance at Nezuko a few more times. It was clear that this girl really liked the man who liked to give people nicknames.

After finishing her meal, Shinobu Kocho put down her chopsticks, picked up her medicine box, and headed outside. She first glanced at Genya Shinazugawa, the strong young man who was already enduring the pain of his injuries.

Shinobu treated him and, seeing the boy's resolute expression, said nothing.

Just like how, back then, because I was too weak, I could hardly cut off the neck of the evil spirit, so I had to find another way and take a shortcut.

Even so, we saw hope only with a bit of luck.

Shinazugawa Genya is somewhat similar to her, or even worse. At least she is weak but can still learn 'breathing techniques', while this demon hunter is so physically weak that she can't learn 'breathing techniques' at all. How can a demon hunter who can't learn 'breathing techniques' hunt demons?

In any case, she couldn't see any hope in Shinazugawa Genya about embarking on the path of demon slayers.

After treating Shinazugawa Genya, Shinobu Kocho carried her medicine box to an open space halfway up the mountain. There, more than twenty teenagers were undergoing training.

Su Mu explained his understanding of "Sun Breathing" to everyone, while Tanjiro demonstrated it. Urokodaki Sakonji, wearing a tengu mask, further explained what Su Mu said, allowing everyone to understand more clearly. For some individuals, he could provide more targeted explanations.

"Miss Shinobu has arrived."

Upon seeing Shinobu Kocho arrive carrying a medicine box, Su Mu smiled.

"Ah."

Butterfly nodded without a smile, glancing briefly at the man's handsome face. If you didn't give her a nickname, he was actually quite a nice guy.

"Soon, these people will begin learning 'Sun Breathing,' so please keep an eye on them, Miss Shinobu."

"no problem."

Shinobu Kocho nodded, opened her medical kit, and began making some preparations.

Su Mu didn't say anything. After giving a brief explanation, he let everyone begin formal training.

Because Nezuko and Tanjiro both learned the 'Sun Breathing' technique, Su Mu still had high expectations for these people. Moreover, it was clear that these were all selected young men with excellent physical abilities.

However, the ending was beyond his expectations.

Several people had to stop as soon as they started trying to 'breathe' because their throats were too swollen and painful. Soon after, several others felt a burning sensation in their chests and abdomens and were unable to continue.

Shinobu Kocho quickly stepped forward and began treating these people.

Aside from some who couldn't withstand the scorching heat and violent energy mixed in with the 'Breathing of the Sun', there were others who couldn't even enter the 'Breathing' state at all.

"This 'breathing' has very strong energy and is very harmful to the body. Even if these people have good physical fitness, they still find it difficult to continue."

After treating another boy's injuries, Shinobu Kocho came over with her medicine box, saying, "This 'breathing' is too domineering."

Su Mu remained silent, looking at the seven people who were already clutching their throats, the eight people who were clutching their chests, and the five or six who were completely bewildered. Only two people seemed to have started to maintain a certain rhythm of 'Sun Breathing', but even so, these two people showed extremely painful expressions on their faces.

“It seems that this kind of ‘breathing’ is difficult for others to inherit.”

Urokodaki Sakonji also walked over, sighing softly, and looked at Su Mu with a hint of admiration: "Speaking of which, it's really extraordinary that you can master such a powerful 'breathing'."

"I only managed to learn 'Sun Breathing' by sheer luck. However, those who cannot withstand 'Sun Breathing' can only learn 'Water Breathing' from Urokodaki-senpai."

Su Mu said a word

"I will teach them this, but there are still two who should have a chance. We will focus on training these two. However, seeing that the others are still unwilling to give up, they will probably continue to try. We can let them continue to try."

"This is the only way."

Su Mu nodded.

He originally intended to train a large number of swordsmen who had mastered the 'Breathing of the Sun' technique, so that when the Infinity Castle opened, he could give Muzan Kibutsuji a huge surprise.

However, it is clear that it is wishful thinking to try to control a large number of initial swordsmen; at most, a small number can be trained.

Of course, with a large enough base, it is possible to cultivate a certain number of initial swordsmen.

However, the Demon Slayer Corps is, after all, an unrecognized, unofficial organization. These twenty-odd people were probably carefully selected from hundreds of people with excellent physical qualities. As for selecting a larger number, that is beyond the Demon Slayer Corps' control.

After listening for a while, Shinobu Kocho began to silently treat these people.

With Shinobu Kocho, a highly skilled physician, there's no guarantee that these people won't encounter any problems while practicing 'Sun Breathing'.

However, seeing that only a handful of people could cultivate this domineering 'breathing' technique, Shinobu Kocho was actually quite disappointed. After all, if there were a large number of initial swordsmen, the Demon Slayer Corps' strength would undoubtedly be increased many times over, and the hope of eradicating the evil spirits of this world would be much greater.

…………

After teaching the others how to cultivate, Su Mu casually sat down to rest on a nearby bluestone.

These boys and girls did not slack off because of his rest; they continued to practice diligently. Some boys and girls who were confirmed unable to learn 'Sun Breathing' have now begun to learn 'Water Breathing' from Urokodaki-senpai.

Almost everyone worked hard

You can sense the inner world of most people through their actions.

Most people seem to harbor a hidden hatred towards ghosts.

Although Su Mu didn't know much about these people's past, he roughly understood that most of them probably had their happiness destroyed by ghosts, with the scent of blood on their bodies.

"Hey……"

A clear, girlish voice rang in his ears, and Su Mu couldn't help but turn his head.

But Shinobu Kocho appeared beside him at some point, carrying a medicine box, which made him look at her with some confusion.

"Everyone else is working hard, everyone else is training like crazy, but you're just being so lazy?"

The girl's face was tense, with a hint of scolding in it.

Su Mu was speechless for a moment.

At this moment, Shinobu Kocho put down her medical kit and drew her Nichirin Blade.

The tsuba has a four-lobed guard, a lotus-green hilt, and a slender blade with a barb at the tip. The words "demon" and "annihilation" are engraved on the sides of the blade.

"Today, I'm here to give you some pointers."

"Give me pointers?"

Su Mu was taken aback for a moment, then asked with some confusion, "Miss Ren, why do you think she's definitely better than me?"

"Men who like to talk badly about others behind their backs are generally not very capable."

Shinobu Kocho's face tightened, and she spoke with a serious expression.

The girl's matter-of-fact attitude left Su Mu speechless.

Moreover, it seems the girl is still quite petty and hasn't forgotten that she mentioned being a hobbit.

"Come on, or are you afraid?"

Shinobu Kocho gently stroked the blade, a cold smile playing on her lips: "How dare you, man who likes to gossip behind people's backs?"

"I just think that if you lose, what I'm saying now will embarrass you."

Su Mu gave a wry smile.

"I can't lose."

Shinobu Kocho slightly raised her head, revealing her long, fair neck, like a beautiful white swan.

Su Mu sighed softly, saying nothing, but drew his own Nichirin Blade from his waist, looked at the confident girl opposite him, and then bowed slightly:

"Su Mu, please give me your guidance."

Shinobu Kocho was slightly taken aback, thinking this person would back down, but she didn't expect him to actually agree. A hint of excitement appeared in her eyes, and she had already imagined how pitifully this person would be beaten.

Although she was incredibly excited, Shinobu Kocho still bowed slightly:

"Shinobu Kocho, nice to meet you."

Chapter 167 The Line of Flaw

"Shinobu Kocho, nice to meet you."

Shinobu Kocho bent down slightly, and after speaking, she gripped the hilt of her sword, waiting for the attack from this incompetent man who only liked to talk behind people's backs.

But... no.

Su Mu remained standing in the same spot, quietly watching her, his handsome face bearing an infuriating smile.

"Why aren't you making a move?"

Shinobu gripped the hilt of her sword, speaking with some annoyance.

"It's never very polite to make the first move on a lady."

Su Mu said something.

"Is it polite to talk badly about women behind their backs?"

Butterfly Shinobu's tense little face let out a cold laugh.

Su Mu shrugged helplessly, looked at the girl's delicate face, and said softly, "Miss Ren, you can't keep thinking I'm talking badly just because I told the truth, although... sometimes the truth hurts more than lies."

"call……"

The girl's breathing suddenly became rapid, and her beautiful purple eyes narrowed, radiating an extremely dangerous light.

"I hope you'll continue to be so talkative."

Shinobu gritted her teeth and said something. The next second, her figure flashed and she appeared to Su Mu's side. The slender Nichirin Blade was already slashing out. When it was about to fall on Su Mu, it hesitated slightly, as if it was afraid that Su Mu's strength was not enough and that it would really hurt him.

Although I'm annoyed that this person gave me a nickname, I won't actually hurt them because of it.

At most, she would just give him a friendly look or teach him a lesson; she would never actually use her Nichirin Blade to cut him. At this moment, Shinobu Kocho regretted not using a wooden sword.

That way, there wouldn't be so much danger if I hit someone, and I wouldn't hesitate like I am now.

"clang!"

The hesitant strike was blocked by Su Mu's casually raised Nichirin Blade, the collision producing a clanging sound like metal clashing.
