Hiding in the sand, splitting into many places, starting with Arkham

Kai Gaku had provoked him first, something Sangishima Jigoro witnessed firsthand.

Beating him up was nothing, but killing him would be a big problem.

At this time, Kai Gaku hadn't committed those heinous acts yet, and hadn't even graduated from Sangishima Jigoro's tutelage, nor passed the final selection on Mount Fujikasane. In everyone's eyes, he was just an ordinary aspiring swordsman with a slightly nasty personality, but good talent, and diligent in his training.

If he really killed this person here, not only would he not learn the Thunder Breathing, but he would also offend Sangishima Jigoro, a leading figure in the Demon Slayer Corps with great influence, who had cultivated many Thunder Breathing users.

"You lost."

Shimizu shook his head, looking regretful.

Kai Gaku stood dumbfounded in front of Shimizu, the sword in his hand falling to the ground.

He felt the fear of death.

In the past, Sangishima Jigoro and others had held swords to his neck, but even combined, they didn't make him feel as terrified as this time.

This person in front of him had killed people, killed many people!

That killing intent was definitely not fake!

Shimizu's main body in the Naruto world, and his avatar in the DC world, were both figures with blood on their hands. The number of people who died at their hands definitely reached three figures.

His innate and powerful desire to survive kicked in, causing him to turn his pleading gaze to Sangishima Jigoro.

Shimizu sheathed his long sword and said to Sangishima Jigoro with a smile.

Wasn't it said that this child was from a noble family? Why does he have such killing intent?

Such killing intent reminded Sangishima Jigoro of the current Wind Pillar.

He felt somewhat puzzled, but he quickly dismissed the doubt.

Perhaps Shimizu had some past story, but there were many people in the Demon Slayer Corps with stories. Anyway, after entering the Demon Slayer Corps, it would be a good thing to use this killing intent against demons.

Sangishima Jigoro dismissed Kai Gaku, asking him to take Agatsuma Zenitsu to find a place to stay, leaving only himself and Shimizu in place.

"I knew long ago that with Kai Gaku's personality, he would suffer a big loss sooner or later. This time can be considered a good thing, letting him experience some hardship, hoping he can change his temper, better than stumbling later."

Sangishima Jigoro leaned on his cane, looking at Shimizu.

"It is easier to move mountains than to change one's nature. If a person does not encounter a drastic change that is deeply engraved in their mind, it is difficult to change their personality."

Shimizu said, watching Kai Gaku grab Zenitsu's arm unceremoniously and leave.

After this incident, before Kai Gaku thinks he is stronger than himself, he will definitely not dare to cause trouble again.

That was enough, after all, Shimizu only wanted to learn Thunder Breathing. After learning it, there would be plenty of time to handle Kai Gaku.

"Ah, it's good if he can change even a little bit."

Sangishima Jigoro shook his head and looked at Shimizu.

"However, I am indeed a little curious like Kai Gaku. In my opinion, Shimizu, you have a very high compatibility with Wind Breathing, and your strength is also very strong. Apart from the Pillars, there may not be many people in the Demon Slayer Corps who can be your opponent. Why are you interested in Thunder Breathing?"

"Wind Breathing is too simple. After I learned it for a month, Master Morioka had nothing more to teach me. But there is still some time before the next selection on Mount Fujikasane. Since I'm idle anyway, I might as well learn other breathing techniques, maybe one will suit me better?"

Sangishima Jigoro: …

Is this human language?

"Then I would like to know, Shimizu, how long will it take you to learn Thunder Breathing? This is the most difficult of the five basic breathing techniques to learn. Even Kai Gaku, after my long-term guidance, has only learned three forms."

"Then shall we start now?"

"So fast? But it's okay, the key to using Thunder Breathing is speed!"

Sangishima Jigoro chuckled, raised his cane, and began to demonstrate it as a katana.

"This old man lacks a leg, so the demonstration is not perfect, but you must listen carefully!"

Shimizu watched this scene and called out in his heart:

"Main body! Help me!"

Naruto World.

On the plain outside the camp, Shimizu, who was starting to study the nature transformation of lightning release, stopped releasing lightning release chakra and pulled out his ninja sword from his back.

"Thunder Breathing First Form: Thunderclap and Flash!"

Sangishima Jigoro's figure instantly turned into a golden lightning bolt and rushed forward.

"Remember, the key to using Thunder Breathing is to simultaneously mobilize multiple muscle tissues for an explosion in an instant…"

Every time Sangishima Jigoro demonstrated a move, he would stop to give a detailed explanation, and Shimizu would synchronize the main body's questions.

The demonstration and explanation of the six forms of Thunder Breathing took more than an hour in total.

Without error, he looked at it all!

Afterwards, Sangishima Jigoro took out a small booklet from his pocket, the same as when Morioka Niren taught Wind Breathing.

"You can just take a look at the contents of this textbook. After all, it was written by me more than ten years ago, and some places can still be improved. I just told you that if you thoroughly understand what I said, it's hard to say whether you can become a Pillar, but mastering Constant Concentration Breathing and becoming a Class A swordsman is more than enough."

Sangishima Jigoro stroked his white beard and said with pride.

"Thank you, Senior Sangishima."

"Well, you can practice slowly first. I'll go see how Kai Gaku and Zenitsu are doing, hoping these two kids can get along happily."

Sangishima Jigoro nodded to Shimizu and turned to leave.

Facts proved that the effect of lightning energy affinity was still very good.

However, there was still a certain gap compared to airflow manipulation.

When he first learned Wind Breathing, after only understanding the basic knowledge and watching it once, the avatar in the DC world was able to basically use it. The reason why it took three days was because Morioka Niren was inconvenient and taught slowly.

It was also possible that, as Sangishima Jigoro said, Thunder Breathing was indeed one of the two most difficult of the five basic breathing techniques. In short, it took Shimizu much longer to learn these six forms of Thunder Breathing than Wind Breathing.

A week.

"A week!"

Sangishima Jigoro slapped his forehead and grabbed his hair.

"Am I dreaming, or am I just senile?"

The little old man had an expression of doubting his life.

Kai Gaku's mouth was even wider.

What madness did I do last week to offend such a thing?

However, Kai Gaku firmly believed that as long as he could continue to live, he would eventually have a chance to defeat Shimizu.

Only Zenitsu, who didn't understand what this concept meant, put down his wooden sword and sat aside to slack off.

"Ah, it's a bit difficult. It actually took me a full seven days to learn."

Shimizu said with a serious face.

It's another day that's right on schedule…
