I teach kendo in the ninja world

The Land of Water, the Hidden Mist Village.

There was a rumble in the valley, and a waterfall cut diagonally down from the not-too-high peak, pulling out a silver-white bolt and slamming it into the deep pool below.

Look down.

Under the majestic waterfall, a young man with black hair and a bare upper body could be vaguely seen.

He closed his eyes and sat cross-legged on a small slippery boulder in the pool. He allowed the flowing curtain of water to wash over his body, but his figure was as solid as a rock and remained motionless.

The water hit his lean muscles and kept splashing, vaguely seeming to form a layer of tiny water droplets covering his whole body.If the country of water hadn't seen sunshine all year round, there might have been a rainbow.

Of course this person is Araki.

Suddenly, he opened his lips and teeth slightly and took a deep breath. A cloud of white steam suddenly bloomed in his mouth and nose.

At this time, Araki only felt a slight heat in his lungs, and a warm feeling started from his chest and flowed throughout his body as the blood flowed.

【Breath of the Sun】!

This felt very familiar. He knew that his physical fitness had been strengthened in all aspects compared to just now.

However, this is far from the effect he wants to achieve!

As these days pass, the practice of [The Art of Cutting Rain] is making steady progress, and success is just around the corner.

But the practice of integrating natural energy and breathing methods was not so smooth.

He has mastered the simple breathing method, but after inhaling the natural energy, he is always missing the mark on how to prepare chakra for immortality.

The main reason that affects the progress is that his chakra is limited, so the number of times he can try every day is too few.

If he practices through shadow clones, after two or three rounds of failure, the remaining amount of chakra will not be enough to support him to continue exploring.

So he learned from the pain and decided to solve this problem fundamentally, first improving his physical fitness.

After all, chakra comes from the body and mind. As the body becomes stronger, the amount of chakra will definitely increase.

This is the saying goes: sharpening a knife does not stop chopping wood. If you want to do your job well, you must first sharpen your tool. This is the truth.

However, physical fitness depends more on innate talent.

For example, the chakra of Senju, Uzumaki, Kaguya and other immortal human bloodlines is naturally calculated in tons.

It is very difficult for ordinary mortals to improve through their own hard work.

For the average person, there seems to be no other way besides years of physical training, and the effect may not be very obvious.

Fortunately, Araki has plug-ins.

Pranayama can do this.

This can be said to be one of the advantages of breathing method over [Eight Gate Dunjia].

Although its explosive power is not as good as its counterpart, it is not just a means of explosion, it can also fundamentally enhance the practitioner's physical fitness.

The practice of breathing method is divided into three stages.

The first stage is to concentrate on breathing.

This is the initial stage of breathing practice. The effect is that through long breathing, oxygen can be spread throughout every cell in the body to improve self-healing ability, stabilize the spirit, activate the spirit, and enhance physical fitness in a short period of time for fighting.

The second stage is called [Full Concentration·Constant Breathing].

This is the first advancement of the breathing method. At this stage, concentrated breathing will become a human instinct and can be maintained 24 hours a day. In other words, the body is being aerobic every minute and every second. in a strengthened state.

Once the breathing method has been practiced to this stage, it is not just an explosive combat skill, but can slowly enhance one's physical fitness over time.

To use a more understandable term for analogy, that is - the art of vomiting and inhalation.

Of course, because of the world view setting, it cannot develop internal strength.

Araki is actually at this stage now.

However, Araki was still a little dissatisfied with the first advancement of the breathing method, [Full Concentration·Changzhong] Breathing, which kept the state of the breathing method at all times, and then subtly and slowly strengthened the physique.

This speed is still a bit too slow.

Therefore, he decided to try the second advancement of the breathing method - turning on markings.

Marking is the third stage of breathing practice. Once activated, physical fitness will be greatly enhanced.

Therefore, it is also difficult to advance this time.

The method is to run the breathing method to the limit that your body can bear, and then strive to cross this hurdle. If you don't die, you will.

If you can achieve this step, your body's all-round qualities will be greatly enhanced, including strength, speed, perception, resilience, etc...

The whole person seemed to have been completely transformed.

The external manifestation of this change is that mysterious lines will appear on the face of the practitioner. The pattern and color of the lines correspond to the breathing style they practice.

For example, if you practice water breathing, the markings will be in the shape of water droplets, if you practice sun breathing, the markings will be in the shape of flames, and so on.And each person will have different patterns according to their own characteristics.

Therefore, it was named [Zebra].

Through the anime "Demon Slayer: Kimetsu no Yaiba", Araki clearly remembers the basic prerequisites for turning on stripes——

The heartbeat exceeds 39 beats per minute, and the body temperature exceeds [-] degrees.

This is an extreme state that normal humans can never reach.

In other words, if someone really achieves it and can continue to practice the breathing method and remain immortal, then he is qualified to turn on [Spots].

(PS: Please do not imitate dangerous actions. No one will really try it, right?)

Therefore, after taking the first breath, Araki did not slow down his movements as usual. Instead, before the heat dissipated, he opened his mouth again and took a long second breath!

laugh--

The white mist around his mouth and nose became thicker and thicker.

At this time, his lungs had begun to feel a slight stinging sensation, just like after an intense exercise.

But it's not enough!

It is far from reaching the limit that his body can bear!

He opened his mouth again and took a deep breath!

Another ball of white mist spurted out from his mouth and nose. At this moment, Araki felt as if he had swallowed a ball of burning fire. The fire ball rolled violently into his throat, and then quickly spread along the trachea and all the alveoli. , a terrifying temperature swept through the whole body in the blink of an eye, and then heartbreaking pain began.

That is not a real high temperature, but an illusion caused by organ pain.

The effect of these overlapping breaths is not addition, but multiplication, or even exponentiation!

After taking three sips in a row, Araki felt that his whole body was hot and his heartbeat was clearly audible.

But it's not enough!

He can still bear it!

So he continued to breathe.

The fourth bite!

Small beads of sweat began to appear on Araki's face, although they would be washed away by the water of the waterfall as soon as they appeared.

The fifth bite!

At this time, the burning pain was not limited to the trachea, lungs and chest, it had flowed throughout Araki's body along the blood vessels.

This made the skin all over his body appear a pink color as if it had been steamed.

The sixth bite!

At this time, the pain was not only flowing downward throughout his body, but also the brain above him began to throb faintly. He seemed to feel that his brain was about to start boiling.

This somewhat affected Araki's perception and judgment, making him feel that the whole world was roaring, especially the "rumbling" waterfall behind him!

At this moment, it was [Ming Jing Zhishui's] state of mind that kept him clear in his mind.

The seventh bite!

His skin was no longer just pink, but as red as braised prawns, and even the water droplets splashing on his body were scalded to the point of smoking.

At this time, the wild trees are surrounded by mist. Viewed from a distance, they look like a fairy.

The eighth bite!

Taking in this breath, Araki felt that the sound of his heartbeat was like thunder in the sky, deafening, and like thousands of horses galloping, as fierce as a drum.It seemed as if he might break free from the restraints of his chest at any moment and jump out.

That's not all. He felt like a fire was burning in his heart. The blood vessels in his body were expanding, and what was flowing in those blood vessels was not blood, but burning magma!

At this time, Araki finally felt vaguely that this should be his limit.

However, he didn't stop there.

Because there was once a sentence that left a deep impression on him.

Practitioners must persevere no matter how painful it is.When you feel that you really can't stand it any longer, remember, that's the time to practice!

"That's right, so now...is the beginning of real practice!"

Araki tried his best to squeeze out a smile on his face, and then took in his ninth breath!

"Suck--"

With this long breath of breath, a flame-like pattern suddenly bloomed on both sides of Araki's cheeks, fresh, dazzling, and eye-scorching, just like the rising sun, the cloud that dyed red when it pierced the sky, giving the darkness The land brings infinite vitality and hope.

And at this moment, the burning sensation that seemed to be burning up his entire body quietly dissipated. As he breathed, the air he breathed into his lungs was no longer burning magma, but became comfortable. The breeze is cool and comfortable, no longer accompanied by pain!

Moreover, a warm current suddenly appeared in his body, starting from the heart and sweeping through the whole body, like a rushing warm river, flowing through every blood vessel and penetrating into the muscles and bones.

He seemed to hear a series of subtle sounds coming from his body. His bones began to become harder and denser, his muscles became more elastic and tight, and a powerful and surging force surged through his body like a sea!

"Uh..."

The feeling of having all the cells in the body soaked by the warm current is so refreshing, especially after just experiencing the scorching purgatory like before.

The strong contrast between before and after made Araki couldn't help but moan.

And he also discovered that this warm current was not a one-time consumable. With every breath he took, the air flow circulated in the lungs and was transported to the heart. The warm current would be continuously produced and flow throughout the body along with the blood.

Tempering bones, strengthening muscles, endless.

"Is this the benefit of turning on stripes?"

Araki stood up and casually punched the side.

"Woooo-"

The buzzing air told the weight of the punch he just struck.

Feeling an unprecedentedly strong body, Araki excitedly took out an ordinary long sword, without any chakra attached. Simply relying on the power of his body, he struck the waterfall behind him with a sword!

Swish!

A cold light flashed.

Boom!

The Milky Way, which was flying downwards, exploded into pieces and rolled upwards.

The beads and jade splashed like scattered flowers.
