I teach kendo in the ninja world

Concentrated Breathing Technique is a general name for a technique developed by the Demon Slayer Corps in order to fight demons with human bodies.

Its main function is to strengthen human heart and lung function, absorb a large amount of oxygen into the blood through breathing, and then instantly greatly increase the physical ability, thus having physical fitness comparable to that of a ghost.

As for the ghost, it is an immortal monster with extremely strong physical fitness, super strong regeneration ability, and can be understood as a modified and enhanced version of a vampire.

So, in short, the full concentration breathing method can be simply understood as a powerful move that improves instantaneous explosive power. Its function can be compared to the [Eight Gate Dunjia] in the ninja world.

However, its effect is not that powerful, and its side effects are not that severe.

However, the best thing about the breathing method is that after practicing it to a high level, this state can be solidified and maintained in a normally open state.

This state is called [Full Concentration·Chang Zhong].

And this is something [Eight Gate Dunjia] cannot do no matter what, so from this aspect, it is stronger than [Eight Gate Dunjia] which can only burst out briefly every time.

Following Kamado Tanjiro's movements, the Nichirin sword in his hand turned into a blue color, flashed with a sharp cold light, and cut mercilessly towards Araki's neck!

"Water to adjust the cutting head..."

Araki smiled softly when he saw this, and after making a joke, with a thought in his mind, the light green sword edge spurted out from the hilt.

Although he has now mastered the swordsmanship of the three attributes of wind, water and thunder, his favorite swordsmanship is the wind-controlling swordsmanship to use against enemies.

I don't know why.

Ding!

The cyan light blade collided gently with the blue sun blade, sparks bloomed, and both sides with equal strength retreated.

Araki took advantage of the gap between Tanjiro's body in the air and instantly extended the sword blade, like a spear, piercing his chest and abdomen.

Tanjiro, who had not yet landed, calmly took in another breath.

"The second type, the waterwheel!"

He swung his arms in a circle, driving his body to spiral in mid-air. The sword-like light traveled around him, drawing a standard circle in the air.

Just like the waterwheel used by farmers to collect water on the banks of the rural river.

This move combined offense with defense, blocking Araki's thrust and protecting him from landing safely.

Even so, he was pushed back a relatively long distance by the stab.The moment he landed, cracks suddenly appeared on the ultra-long blue sword in Araki's hand.

This is a scene that shouldn't happen.

Because Araki's sword has no entity, everything is just the embodiment of chakra.

But precisely because of this, Araki is even more comfortable in controlling them!

crunch~

The spiderweb-like lines gradually began to spread to the entire sword body. It seemed that the Nine Heavens Gang Wind was blowing hard inside the sword body. They were originally bound by the tangible sword body. Now the blade is about to crack, and the wind seems to be destroying the world. The violent breath of the earth can no longer be suppressed!

boom!

Suddenly, the sword body, which was more than ten meters long, shattered into pieces and turned into curved blue crescents. Thousands and countless of them were like torrents, like wind disasters, rushing forward and behind, rushing towards Tanjiro. Rush away!

[Zhanbo·Bengyue]!

This move is Araki's improvement on the previous sword skill [Zhanbo·Qianyue].

[Zhanbo·Qianyue] He needs to swing his sword dozens of times in succession to create a surging sword storm.

Although the power is good, the attack is too slow, and in many cases it is too late to use it.

After all, Araki doesn't have the ability to kill thousands of people in an instant, so he uses the lightning speed sword.

This move [Collapse Moon] just solves this problem.

The long enough sword blade will be shattered from it and turned into countless small cutting blades.Perhaps the power of each slash is not as powerful as striking it with your own hands, but its suddenness is enough to make up for the slight lack of power.

As soon as Tanjiro landed, a raging storm hit him.

woohoo~

The sound of wind hits my ears, cutting my face like a knife.

Feeling this power, he knew very well that if he was enveloped by this wave of swords, he would definitely be attacked by thousands of swords cutting through his body and thousands of swords piercing his heart.

He is not his younger sister Nezuko. She does not have the kind of super self-healing ability that can regenerate a broken limb.

However, he was not panicked even though he had experienced many battles.

I saw him gritting his teeth and inhaling again!

"Breath of Water, Three Forms, Flowing Dance!"

In an instant, his figure seemed to turn into soft water, every step he took and every turn he took were so natural and just right.

His figure was like flowing water, turning around and around again, moving left and right, flying up and down, fighting bravely in the blue tide of sword energy.

Just like a petrel flying through the storm, it received all the attacks without any damage.

After Wushang passed through the wave of sword energy, Tanjiro's body twist did not stop there.

He held the knife in both hands, twisting his legs, waist, torso and arms in a strange rhythm, generating extremely powerful force. The light of the knife roared like a whirlpool tornado.

"Full concentration - Breath of water, shape of land, twisting vortex!"

Aggressive!

The twisted body produced extremely strong force, even like a real whirlpool, there was an attraction pulling Araki towards his blade spontaneously.

Araki's eyes lit up when he felt this power, and he was not surprised but happy.

Before he could make a move, the other side drew a dotted line. What kind of supreme VIP treatment is this!

There was a smile on his lips, and the tornado danced around him, flying forward with this force.

【Blaster of Absolute Breath】!

In an instant, the two met in mid-air, the storm and the whirlpool merged, and the cyan sword blade faced the blue Nichirin sword.

Ding Ding Ding Ding!

The sound of gold and iron chiming is endless, and the sound is as dense as rain hitting banana trees or beads falling on jade plates, overlapping and noisy.

After the turbulent battle lasted for a while, Araki discovered that with the ability of [Mind Eye] to capture flaws, he failed to take any advantage in this happy battle.

Whenever he sees the opponent's flaw and makes a move, Tanjiro is always able to adapt to the situation and take advantage of the opponent's attack without falling behind at all.

Recalling Demon Slayer's skill tree, he couldn't help but ask:

"See through the world?"

Tanjiro responded seriously while taking action: "This is the [Supreme Realm] that I reached after working hard and enduring pain. I didn't expect you to be able to do it too. It seems that you are indeed a respectable opponent!"

"Me... that's right."

After hearing what Tanjiro said, Araki pondered for a moment but did not correct him.

The so-called "Transparent World", as Tanjiro said, is the "Supreme Realm" that can only be reached after working hard and enduring pain.

Its specific manifestation is that the mind becomes transparent and reflects everything.In this state, humans can turn off their redundant senses by concentrating.

It has two effects against the enemy and against oneself.

When facing an enemy, the opponent's body will appear to be transparent, the blood flow in the opponent's lungs can also be clearly seen, and the contraction of the muscles can be grasped faster, and the enemy's attack route can even be predicted based on this.

For yourself, you can also grasp your own blood flow, muscle contraction and other conditions more keenly and clearly, and your own movement speed, attack and avoidance abilities are significantly improved.

How about it? Put it this way, do you think it has a very similar function to a skill?

That's right, predicting the opponent's attacks and strengthening your control over yourself, isn't this the [mind's eye]!

The only difference is that the mind's eye cannot see through the other person's bones and internal organs.

Well, you can't say that either.

[Transparent World] The so-called seeing actually does not rely on the eyes, but on the perceptive ability of the brain.

So, in general, they can basically be said to be the same ability.

This is the fundamental reason why the two people fought "bang bang bang bang" for a long time, but in the end they were evenly matched.

Because a simple description of their battle is actually——

You predicted my attack, and I predicted your prediction, and then you predicted my prediction of yours again...

Endless, repeated matryoshka.

The storm died down.

The two stood more than ten meters apart.

The sword blade in Araki's hand turned from green to purple.

Since the swordsmanship levels of both sides were at par, he had to change his fighting style.

He has mastered enough swordsmanship schools, so he is so willful!

Swish!

The lightning sword blade in his hand suddenly surged, spanning a distance of more than ten meters in an instant, turned into a giant sword, and struck Tanjiro head-on!

Boom!

The sword edge landed on the ground, and purple electric light flew everywhere, "chirping" like a thousand birds singing in unison.

Of course, such an attack could not touch the hem of Tanjiro's clothes, and the opponent had already retreated the moment he drew his sword.

But his purpose was not to hurt Tanjiro.

After the purple lightning giant sword hit the ground hard, it shattered like porcelain, and instantly turned into knuckle-sized thunderbolts that exploded in all directions!

That's right, it's [Beng Yue] again!

However, although they are similar techniques, they have completely different cores.

These Leisuo are not only released to hurt people.

Faced with Araki's repeated tricks, Tanjiro seemed to want to try his best.

He took a deep breath, danced his steps, and flowed endlessly!

"Breath of Water, Three Forms, Flowing Dance!"

Seeing that his opponent had indeed been fooled, Araki curled his lips.

The perception ability of [Transparent World] needs to target living creatures, observe blood flow and muscle contraction, and predict his moves.

So, can you predict which [Thunder Wedge] I will exchange places with?

Swish!

Araki's figure flashed and disappeared from the place.

Tanjiro's pupils suddenly contracted.

At this moment, he suddenly lost sight of the other party!

chi chi-

At the same time, before he had time to turn pale, a thunderbolt that he had just turned to avoid suddenly exploded.

When the purple electric flower bloomed, a sword tip of the same color came out from it.

This sword tip is not just extending forward, it also seems to be alive and growing!

With the combination of the two, in the blink of an eye, the sword edge had touched Tanjiro's side.

It was not until this moment that the young man wearing a Demon Slayer uniform and a green plaid haori suddenly turned around and saw Araki, who had just emerged from the lightning.

Time seemed to freeze at this moment.

Both Araki's [Heart's Eye] and Tanjiro's [Transparent World] seemed to have predicted the result of this sword.

Although Tanjiro has many moves that he has not yet had time to use, but considering the fragile human body, the tip of the sword piercing the side of the ribs can destroy all the internal organs in an instant.

This is already a killing sword.

But even so, Tanjiro did not give up, he still turned around and slashed.

However, there are always surprises in this world.

At this moment when the overall situation was decided, suddenly, a scream came from the wooden box behind Tanjiro.

"Don't hurt my brother!"

In an instant, a young girl broke out of the box, and the green bamboo shackle that had been biting her mouth was gone.

In the process of breaking out of the box, her body was also changing at the same time.

The short arms and legs of a three- or four-year-old girl stretched in an instant, and even her ordinary body completed the transformation like a tall building rising from the ground in an instant.There was even a horn growing out of his forehead.

The sudden change in her body changed the style of her originally very fitting clothes.

The long sleeves turned into short sleeves, exposing her fair arms.The long skirt that originally went down to the ankles has become a very open short skirt, and the long legs are exposed without reservation.

The biggest change was in the flat chest, where the slim-fitting clothes were stretched open, revealing two willow-like patterns clinging to it.

At this moment, Araki drew his sword from behind Tanjiro, which was very close to him.

Therefore, Mi Douzi jumped and changed, and she directly collided with Araki.

However, before he could fully feel the sudden soft touch on his face, he felt a pain in his neck and was kicked out of his conscious space in an instant.
