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

"Breathing Techniques were created four hundred years ago. The original form of Breathing Techniques is impossible to verify, but regardless, the five Breathing Techniques of Wind, Thunder, Water, Flame, and Stone are undoubtedly the five basic Breathing Techniques closest to the original Ancestral Breathing Technique. All subsequent derivative Breathing Techniques were born from this foundation."

Morioka Nen put down the bamboo sword and continued, "The principle of Breathing Techniques is to absorb a large amount of oxygen from the air and, through specific breathing patterns, allow the lungs to transport this oxygen to all parts of the body in a short period of time, in order to obtain physical abilities and explosive power beyond ordinary people. At the same time, reaction speed and recovery ability will also be improved under the effect of Breathing Techniques. Only in this way can we use our flesh and blood to contend with those demons."

Shimizu did not comment on what Morioka Nen said.

If one could achieve such a state simply by absorbing a large amount of oxygen in a short period of time, wouldn't I be invincible with an oxygen mask?

I'd probably suffer from oxygen poisoning due to excessive oxygen concentration.

According to Shimizu's speculation, the Demon Slayer Corps' Breathing Techniques should be a way to capture energy floating in the air. By borrowing this energy, one can gain power when using the Breathing Technique. Absorbing a large amount of oxygen is just to allow the body to better cooperate with the energy.

The people of the Demon Slayer Corps probably detected that the amount of oxygen consumed when using Breathing Techniques was much greater than after normal exercise, leading them to this judgment.

And the energy floating in the air cannot be detected by conventional means.

In this era where technology is still relatively backward, it is reasonable for the people of the Demon Slayer Corps to make such a summary.

"The Breath of Wind has a total of nine sword forms. These were summarized by the initial swordsman of the Breath of Wind based on the breathing methods he learned and the swordsmanship he mastered. Over the past four hundred years, through the improvement of successive Wind Pillars, every move of the five basic Breathing Techniques has been honed to perfection."

Morioka Nen took out a booklet from the house and handed it to Shimizu.

This is the teaching material.

"The sword forms are more difficult for those with a weak foundation in swordsmanship, but with Shimizu-kun's flexibility and swordsmanship ability, as long as you put in the effort, it won't be difficult to master. The real difficulty lies in the Breathing Technique and how to combine the Breathing Technique with the sword forms."

After Shimizu finished reading the secrets of breathing, Morioka Nen explained it in detail again before picking up the bamboo sword and demonstrating it in front of Shimizu.

"Breath of Wind, First Form: Dust Whirlwind Cutter!"

Morioka Nen deliberately slowed down some of the movements. The leg that was not injured quickly stepped on the ground, wielding the bamboo sword, and his figure instantly rushed from one end of the courtyard to the other, leaving a long spiral wind blade behind him.

Shimizu watched this scene intently, while sharing the memory with the main body.

Skills related to wind should be quickly learned by the main body and the Shimizu in the DC world.

Since the Shimizu in the Naruto world could not leave for the time being, he synchronized this part of the memory to the Shimizu in the DC world.

And Morioka Nen began the subsequent moves.

"Breath of Wind, Second Form: Claws-Clawing Purifying Wind!"

"Breath of Wind, Third Form: Clear Air Tree!"

After demonstrating two more moves, Morioka Nen paused slightly, panting a few breaths before continuing with the fourth form.

"Breath of Wind, Fourth Form: Rising Up Dust Storm!"

A tornado composed of countless wind blades shot straight into the sky, but Morioka Nen stopped his movements and sat down on the chair next to him, patting his leg.

"Shimizu-kun, I'm really sorry, this old monk's legs are inconvenient. In order to avoid causing old injuries to relapse, I can only demonstrate the first four forms for now."

Morioka Nen said apologetically.

"It doesn't matter, thank you, Senior Morioka. May I try practicing it first?"

The technique was wrong, and the wind blades condensed on the bamboo sword were not solid enough.

Without being discouraged, Shimizu continued to practice the subsequent sword forms.

Unsurprisingly, he failed to execute them successfully.

The second and third forms were still like the first form, producing a little effect, but the fourth form, which was relatively more difficult, was even more ridiculous.

The old monk sat on the chair under the tree, drinking tea, and watching Shimizu.

In fact, it was not bad to have such an effect the first time. Just as he was about to stand up and point out Shimizu's mistakes, Shimizu suddenly closed his eyes and stood there in a daze.

At the same time.

In the DC world, another incarnation of Shimizu was standing in a vacant area temporarily cleared in the laboratory, holding a steel pipe and performing the moves of the Breath of Wind.

The first time, he executed the four forms almost perfectly. The second time, he even increased the speed and independently repaired some of the flaws contained in the previous time.

He can now learn any wind-related skill almost instantly, as long as he knows the principle and has seen a demonstration once!

After receiving the memory, the main body directly packaged and sent this memory.

Shimizu in the Demon Slayer world opened his eyes, exhaled a long breath, and after simply adjusting his breathing, he once again gripped the bamboo sword tightly.

Morioka Nen looked at Shimizu's posture and keenly noticed the difference from the previous time.

"Breath of Wind, First Form: Dust Whirlwind Cutter!"

A turquoise spiral wind blade was left behind Shimizu, and in a blink of an eye, claw-shaped wind blades flew forward.

"Breath of Wind, Second Form: Claws-Clawing Purifying Wind!"

"Breath of Wind, Third Form: Clear Air Tree!"

Crescent-shaped wind blades scattered around Shimizu, and in the next instant, a tornado formed by rotating wind blades twisted and rolled into the sky.

The old monk Morioka Nen was dumbfounded.

He had taught no less than a hundred swordsmen who used the Breath of Wind, but it was the first time he had seen such a genius.

However, Shimizu was not very satisfied.

After all, this incarnation did not synchronize the superpowers of the DC world incarnation. Although he fully accepted the relevant memories, he did not have the innate ability to be highly compatible with wind. The effect of performing it was still a bit worse than the incarnation in the DC world.

However, Shimizu would not be so extravagant as to synchronize the talent of the incarnation in the Demon Slayer world.

Shimizu was not satisfied with himself, but the old monk could not be more satisfied.

"This old man finally understands why Wind Pillar-sama believes that you have the potential to become a Pillar!"
