Naruto: I wrote in my diary that I exposed the Otsutsuki's arrival.

Chapter 224 Sasuke is also a Pillar, I will rid the world of harm for the Breath of Lightning.

Chapter 224 Sasuke is also a Pillar, I will rid the world of harm for the Breath of Lightning.

There was no aura of chakra, nor the aura of sage techniques, but rather the aura of another inexplicable energy. Clearly, this might be a completely new energy system that he was unaware of.

What makes the ninja world special is that it has many different training systems, many of which are unknown to most people.

The most widely known system is the chakra system, and it wasn't just ninjas who used chakra; samurai also used it.

In addition, there are magic systems that utilize the energy of nature, as well as systems associated with priestesses, and so on.

So when a system he's never seen before suddenly appears, he's very receptive to it.

"So, for these pillars to fully unleash their power, they need the cooperation of a sword. Only when they unleash a sword technique will their aura reach its peak, right?"

Sasuke Uchiha sensed that the aura of the Pillars in the video had significantly increased after they unleashed their sword techniques.

This is clearly the true essence of the breathing technique system.

So this is the breathing technique that Kitahara Kaede taught Uchiha Sasuke today?

As everyone landed, members of the Demon Slayer Corps appeared before them, all of them young faces.

Last to land was Tanjiro Kamado, who landed on a platform. Not far away, on a higher platform, Muzan Kibutsuji's face was contorted with rage; his calm demeanor at the beginning of the video was completely gone. He glared at Tanjiro below and roared, "You think you can corner me like this? You're all going to hell soon! You eyesore demon slayers, tonight I'll wipe you all out!"

"You're the one who's going to hell, Muzan! We will never let you go!"

Kamado Tanjiro roared.

"If you can do it, then give it a try, Kamado Tanjiro!" Muzan Kibutsuji roared.

"We will definitely destroy you, Muzan Kibutsuji!"

Tanjiro Kamado said as he landed.

Upon seeing this, everyone recalled what Kitahara Kaede had written in his diary about the Battle of the Infinite Castle.

So this mysterious space is the Infinite City?

The city truly lives up to its name; it does indeed appear to have a vast and boundless space.

Before they could think any further, the scene shifted, and a golden-haired swordsman sped through the Infinite City.

Everyone remembered that this was one of the Demon Slayer Corps members who had just fallen into the Infinity Castle and made a show of himself.

But he wore a somewhat gloomy expression and sped off into the distance.

"I heard that right, that guy must be nearby."

Wherever he went, ghosts were about to ambush him, but they were instantly killed by him.

"Unforgivable! I will never forgive you!"

There was a hint of coldness in his eyes.

This book was first published on 2009.com, providing you with a reading experience free of errors and disordered chapters.

"Breathing of Thunder, is the first form of Thunderclap Flash."

Sasuke Uchiha recognized the move instantly; in fact, it would have been difficult for him not to recognize it.

After all, he had practiced First Form Thunderclap Flash all day, but the difference was that Zenitsu Agatsuma's Thunder Breathing did not use chakra, while the version he practiced used chakra.

"Has it been specifically modified?"

Sasuke Uchiha didn't delve into where Kitahara Kaede obtained the Lightning Breathing technique; it wasn't important.

Soon, Zenitsu Agatsuma found Kaigaku's hiding place.

"I'm sure he's nearby."

"That guy definitely has to meet with me."

The next second he was in front of a house, coldly saying, "You're in there, aren't you? Come out, I know you're there!"

"That's not the right way you're talking. You're talking to your senior brother like that."

At that moment, a frivolous and mocking voice came from inside the room.

"Since we last parted, you may have become a little stronger, but you're still just as slovenly."

A figure dressed almost like a swordsman emerged from the room, but with claw-like fingernails that made it immediately clear that he was not human.

They also had that ghostly aura about them, a sinister and eerie feeling.

"Long time no see, Zenitsu!"

Only then did everyone finally see his face clearly. He had a face that resembled a human's, but with pointed ears and green eyes. On the left and right sides of his eyes were written the words "Upper Moon" and "Lu".

Everyone immediately realized that this must be the so-called Upper Moon Six mentioned in Kitahara Kaede's diary.

"Upper Moon Six, does that mean there might be Lower Moons as well, and that the Upper Moons might be numbered? If this one is six, then there must have been at least five before." Uchiha Itachi silently made notes on the white paper.

Kitahara Kaede's earlier joking remark that Sasuke had also ventured into the Infinity Castle was seen as a huge deal by Uchiha Itachi. If it were true, this information would be crucial in determining how Sasuke would deal with the demons in the future.

We'll find an opportunity to leave this information for Sasuke, so that he won't be helpless when facing the demons in the Infinity Castle in the future.

"These demons were transformed from humans. The oldest and oldest demon king, Muzan Kibutsuji, has lived for over a thousand years. He possesses incredible regenerative abilities and astonishing cellular vitality, which is likely the reason he has been able to survive for so long. Furthermore, these demons are likely cannibalistic; cannibalism may be a reason for their long-term survival, a necessity." Itachi Uchiha silently noted. "As for the other demons, judging from this demon king's abilities, they must have weakened, meaning they must have weaknesses. Otherwise, the Demon Slayer Corps wouldn't be able to deal with them. These demons fear sunlight, even the demon king."

Perhaps using Amaterasu, known as the fire of the sun, is a feasible solution.

Itachi Uchiha didn't know the exact limit of the Demon King's resurrection, but Amaterasu was also known as a flame that would burn forever as long as it couldn't be completely burned away.

It is also known as the Fire of the Sun, which may be the Ghost King's natural counter.

"They don't have chakra, but they have their own Blood Demon Art system. Each demon should be different. In contrast, the Demon Slayer Corps should have developed different breathing techniques and swordsmanship styles. They must have some way to fight these demons. Otherwise, it's incomprehensible without a chakra-based system."

"The strongest in each breathing style should be what is known as a Pillar."

The video continued as Itachi Uchiha gestured.

"Kaigaku, now that you have become a demon, I will no longer acknowledge you as my senior brother."

Zenitsu Agatsuma said coldly.

"You really haven't changed at all." Kaigaku's face showed a hint of arrogance. "Still a ragged little dwarf, right?"

"What, you've become a Pillar? Come on, Zenitsu, what else have you learned besides the First Form?"

"You're really arrogant, even though you're just the last one in the Upper Moons." Zenitsu Agatsuma's expression was icy cold.

"Looks like you've at least learned to talk back," Kaiyue said nonchalantly.

Zenitsu Agatsuma asked, "Why do you want to become a demon?"

Just as Kaigaku was about to continue speaking, Zenitsu Agatsuma exploded.

"Why did the successor of Thunder Breathing become a demon? If you hadn't become a demon, my grandfather wouldn't have had to commit seppuku. He could have slit his throat or pierced his heart. It's all because a demon emerged from among the successors of Thunder Breathing!"

"What does this have to do with me? So what? Do you want me to weep and confess?"

Kaiyue said with a wicked smile, "I never respect those who cannot properly evaluate me. I only serve those who understand my value. I was very happy when that old man died in pain. I worked so hard, but he refused to let me be his sole successor. That old bastard actually made me share the inheritance with a peasant like you."

He may have been a pillar in his past life, but in his later years he must have become senile.

"What a beast."

Uchiha Sasuke couldn't help but purse his lips and said.

He finally understood that these two were the Zenitsu Agatsuma mentioned in Kitahara Kaede's diary, one who only knew the first form of Thunder Breathing, and the other who could not learn the first form of Thunder Breathing.

This Du Yue turned into a demon in order to gain power, and he felt no remorse towards his mentor who had taught him.

It was because this lineage produced such a rebellious disciple that the master was forced to commit seppuku.

Although he wasn't taught by the old man who was the former Sound Pillar, since Kitahara Kaede had said that he was the best successor to Thunder Breathing, he felt that if there was an opportunity in the future, he wouldn't mind eliminating such a disgraceful beast for the sake of Thunder Breathing.

"Grandpa isn't senile. I may be a peasant, but you're trash. I may only be able to use the first form, but you can't even use the first form. The reason Grandpa died so tragically is because he had a successor like you."

Zenitsu Agatsuma roared.

Kaigaku finally couldn't hold back any longer and drew his long sword from behind him.

"Breathing of Thunder, Fourth Form: Far Thunder"

But before he could draw his sword, Zenitsu Agatsuma slashed his neck, and blood gushed out.

"You're too slow, trash," Zenitsu Agatsuma said bluntly.

"He hit me! So fast! This guy is like a completely different person."

Kaigaku said in shock.

"It's unbelievable. Compared to that kind of fear, this bastard is nothing."

97

"If it had been a ninja, he would have been dead or at least seriously injured and collapsed after being slashed in the neck. But he only bled once. Just as I predicted, these demons have unimaginable regenerative abilities."

Even though there's a significant gap between him and the Demon King Muzan, he's still far beyond ordinary people!

Uchiha Itachi watched the video and saw that the wound on Du Yue's neck had only bled once and then healed.

This is unbelievable. If it were a normal ninja, they would have been killed by now.

At least replacing him wouldn't have yielded a better result.

Although these people do not have chakra, they are extremely fast, similar to those body-training ninjas. Unbeknownst to them, he had already activated his Sharingan to observe the battle.
