Konoha's Hextech Ninja

In the blink of an eye, a complex pattern appeared on the test strip.

"The seal has been triggered! Yoruichi, you have Yang Release!" Shizune exclaimed with delight, then handed another test strip to Yoruichi Yagami and urged, "Try Yin Release next."

"Medical ninjutsu only requires Yang Release, why test Yin Release?!" Tsunade's dissatisfied voice came.

But as she opened her mouth, Yoruichi Yagami had already taken the test strip and injected chakra into it.

There was no reaction; it remained exactly as it was.

"It doesn't have the Yin Release attribute..." Shizune said with a hint of disappointment in her voice when she saw this.

Yagami Yoruichi, however, had a suspicion in his mind.

Yang Dun is related to the body, while Yin Dun is related to the spirit.

He has an extremely strong body and very high physical attributes.

However, her mental attributes are relatively low compared to Yoruichi Yagami's own strength.

It is reasonable from the data panel that it is born with the Yang Dun attribute but not the Yin Dun attribute.

Therefore, one's complete attributes are wind, fire, water, and yang, which are the four attributes.

What about the missing three attributes: thunder, earth, and yin?

Having the Yang Release attribute doesn't mean you have a talent for medical ninjutsu.

For some reason, Yagami Yoruichi detected a hint of anger in Tsunade's tone.

I don't know what I did to upset her.

Yoruichi Yagami didn't dare to speak, listening attentively to Tsunade's instructions: "You probably haven't had any medical knowledge before, so I won't test you with anything too difficult. I've heard you have a good talent for ninjutsu, and since medical ninjutsu requires a high level of chakra control, I'll test your ability in that area. Here's a ninjutsu; if you can learn it before sunset this afternoon, I'll reluctantly acknowledge your talent for medical ninjutsu."

As he spoke, Tsunade took out a small scroll from his pocket and tossed it into Yagami Yoruichi's hand.

Yagami Yoruichi opened the scroll and, seeing the name of the ninjutsu recorded on it, unconsciously read it aloud: "Regeneration Technique?"

"Regeneration Technique?" Although Kosuke Maruhoshi was busy in the kitchen, he had been paying attention to what was happening here. Hearing Yoruichi Yagami's voice, he couldn't help but come out of the kitchen and angrily said to Tsunade, "Tsunade, you've gone too far! You learned a B-rank medical ninjutsu in one afternoon? Don't think I don't know that it took you a week to learn this ninjutsu back then!"

Tsunade is already the strongest medical ninjutsu genius in Konoha's history.

It takes her a week to learn even a B-level medical ninjutsu.

This is based on the premise that she already has a certain foundation in medical ninjutsu.

Yoruichi Yagami has absolutely no foundation in the art. How can she master the 'Regeneration Technique' in just one afternoon?

What's the difference between this 'test' and a direct rejection?

"I only promised to give him a chance." Tsunade remained unmoved and insisted, "My disciple's standards are of course determined by me! You and Uncle Torifu both say he is a once-in-a-century super genius, so naturally he must demonstrate the level of a super genius. Otherwise, why should I make an exception and accept him as a disciple?"

When Yagami Yoruichi saw Tsunade's attitude and combined it with the information in the original work, he knew that Tsunade actually had no intention of taking on a disciple at all. She was only reluctant to refuse directly because of Maruboshi Kosuke's face, so she chose to set this theoretically impossible 'test'.

If she continued, Tsunade wouldn't change her mind.

But should we just give up like this?

That's not like Yoruichi Yagami's personality.

"Lady Tsunade," Yagami Yoichi glanced at the scroll a few times and asked, "If I have any questions while learning this ninjutsu, may I ask you for guidance?"

Upon hearing Yagami Yoruichi's words, Tsunade couldn't help but scrutinize her, thinking to herself that this child had a good mindset.

“Yes, but only before sunset today,” Tsunade said. “If you can learn it before sunset, then consider this ninjutsu my gift to you. If you can’t learn it, you won’t be allowed to learn it again in the future.”

"As for materials for practicing ninjutsu, there are fish in the water tank in the kitchen," Tsunade added.

Although he didn't intend to take on any apprentices, he set a test that was theoretically impossible to complete.

But Tsunade wouldn't give Kosuke Maruboshi a chance to cause trouble; she had everything prepared.

"Thank you, Tsunade-sama," Yagami Yoruichi said, sitting back on the sofa and carefully examining the ninjutsu scroll in her hand.

'Regeneration Technique' is a weakened version, or a budget version, of the A-rank ninjutsu 'Healing and Regeneration Technique'.

The effect is to stimulate cells with Yang Release chakra, thereby accelerating the healing speed of the wound.

However, its effect is much worse than the 'Palm Immortal Technique', and it is generally only used as an auxiliary technique.

The ninjutsu scroll contains detailed information, including techniques for using Yang Release chakra, how to use chakra to stimulate cell healing, and so on.

The principle is not complicated; the real difficulty lies in the extremely high level of chakra control required, which needs to be precise down to the 'micrometer level,' something that many Jonin cannot achieve.

"Micron-level control... I wonder if I can do that now." Yagami Yoruichi tried a few times and successfully converted Yang Release chakra with the 'healing' attribute. She got up and went to the kitchen to test it with a fish.

Chapter 47 Incredibly Difficult Medical Ninjutsu

Knife up and down.

A deep, bone-revealing cut was made on the back of the fish on the cutting board.

A green light emanated from Yagami Yoruichi's hand, a manifestation of the Yang Release chakra gathered to its extreme.

"The Art of Regeneration!"

Yagami Yoruichi placed her palm on the fish's wound, attempting to stimulate the cells in the wound with Yang Release chakra to heal it.

The effect was very obvious, but it was different from what Yagami Yoruichi had guessed.

Stimulated by the Yang Release chakra, the cells at the wound site proliferated wildly, quickly growing into a large cluster of irregular sarcomas.

Clearly, this ninjutsu failed.

"Was it too stimulating?" Yagami Yoruichi wondered thoughtfully.

The first release failed, just as Yagami Yoruichi had anticipated.

Medical ninjutsu is difficult in itself, let alone B-rank ninjutsu, which is considered one of the more difficult medical ninjutsu.

It would be truly outrageous to succeed on the first try.

But to say that 'stimulating wound healing' turns into 'growing a large cluster of sarcomas' is a huge deviation.

"It's probably because too much chakra is being inputted. Try reducing the amount of chakra."

Yoruichi Yagami threw the nearly dead fish into the trash can, grabbed another fish, skillfully cut open the wound, and then activated her Yang Release chakra to try to stimulate the cells and speed up the healing process.

This time, no large, terrifying-looking tumors grew out again, but the wound showed no signs of regrowth.

"If too much chakra is inputted, the cells will divide excessively, resulting in a bunch of strange tumors growing. If too little chakra is inputted, it won't stimulate the cells to divide faster, thus failing to promote rapid wound healing. Finding the right balance seems difficult..."

Yagami Yoruichi had already understood the difficulty of this ninjutsu through the records on the ninjutsu scroll.

Having experienced two failures, a little analysis reveals the key.

However, knowing something is one thing, but there is still a considerable gap between knowing it and actually mastering it.

It's commonly said that you can understand it in your brain, but you haven't learned it in your hands yet.

With each attempt and each failure, a fish dies with its eyes wide open in dismay.

Moreover, most of those fish died in bizarre ways, giving the impression of being spiritually polluted, and they had no value as food, so they had to be thrown away.

Fortunately, Tsunade had clearly anticipated this and prepared a large tank of fish, enough for Yoruichi Yagami to practice with.

Time passed without her noticing, and suddenly, Yagami Yoruichi smelled a fragrance.

Turning my head, I saw that Kosuke Maruhoshi had just opened the lid of a ceramic pot and was stirring the chicken soup inside with a spoon.

The chicken soup emitted an enticing aroma, instantly making Yagami Yoruichi feel a surge of hunger.

"Let's take a break and go out for something to eat," said Kosuke Maruhoshi with a smile. "This is Tsunade's favorite chicken soup recipe, which I learned from another master."

Whether it's out of interest or some other reason, Kosuke Maruhoshi really enjoys studying cooking.

Even when he goes on missions, he likes to carry a large iron pot on his back.

Yagami Yoruichi was fortunate enough to taste the food made by Maruhoshi Kosuke a few times, and it was indeed very appetizing and delicious.

Upon hearing Maruhoshi Kosuke's words, Yagami Yoruichi quickly put down the fish, washed his hands, and served several bowls of chicken soup to the restaurant.

"Tsunade-sama, Shizune, dinner's ready," Yagami Yoruichi called out.

"Uncle Kosuke's cooking skills are truly amazing, almost on par with Grandma's." Tsunade looked nostalgic as she picked up a bowl of chicken soup, sipped it slowly, and showed a satisfied expression.

grandmother?

Tsunade's grandmother, wasn't that Mito Uzumaki, the first Nine-Tails Jinchuriki?

At this time, I wonder if the Nine-Tails has already transferred into Kushina Uzumaki's body?

Based on the Shippuden storyline, Kushina Uzumaki was still in school when she became the Nine-Tails' Jinchuriki.

However, in the later "Minato Chronicles", Kushina Uzumaki was kidnapped by the Hidden Cloud Village ninja after graduating. She was rescued by Minato Namikaze and it took several years before she became the Nine-Tails Jinchuriki. Based on this timeline, it seems that there were still a few years left. In other words, Mito Uzumaki may not have died during this time.

However, given Mito Uzumaki's age, even if she hasn't transferred the Nine-Tails yet, she's probably already very old and unable to move around much.

While Yagami Yoruichi was guessing what was going on in his mind, he remained outwardly calm and pretended not to have heard anything.

Kosuke Maruhoshi looked at Tsunade and said, "Tsunade, if you take Yoruichi as your disciple, I'll make you chicken soup often from now on, how about that?"

Upon hearing Maruhoshi Kosuke's words, Tsunade showed a hint of interest, but quickly shook her head and said, "If I want some chicken soup, I can go to Grandma! To become my disciple, you have to rely on your real skills. Don't expect me to lower my standards!"

Upon hearing this, Yagami Yoruichi immediately understood that Uzumaki Mito was indeed still alive at this time.

However, when it comes to matters involving high-ranking figures in Konoha, Yagami Yoruichi would simply pretend not to hear them.

Avoid getting involved in things that don't concern you until you have sufficient strength.

When it comes to the Nine-Tails Jinchuriki, that's a big deal.

With my current abilities, let alone mixing in, even knowing too much would be dangerous.

"Tsunade-sama," Yagami Yoruichi began, changing the subject, "When I use the 'Regeneration Technique,' I feel I can precisely stimulate cell growth, but it's difficult to accurately control the newly generated cells to heal the wound. Is there anything I should be careful about?"

"Oh? You can precisely stimulate cell growth? You've only just started learning, and you're already this good?" Tsunade looked surprised.

After a moment of blankness, she said, "After we finish eating, you can demonstrate it for me. I need to see it to know where the problem is."

"Yes, Tsunade-sama." Yagami Yoruichi replied, lowering his head to concentrate on eating.

After the meal, Tsunade and Yoruichi Yagami went to the kitchen.

"Now let's demonstrate." Tsunade flicked her finger, and a ball of chakra shot into the basin of water, accurately stunning a fish and sending it flying onto the cutting board.

Yagami Yoruichi took out her sword and made a cut on the fish's body. Then, she used the "Regeneration Technique" and Yang Release chakra to stimulate the regeneration of cells at the fish's wound.

Tiny granulation tissue grew from the wound, but instead of healing it, it piled up in one place, causing the wound to stretch and tear further.

“Of course you can’t do it that way. Before using the regeneration technique, you have to close the wound.” Tsunade said impatiently, “It’s like welding two steel plates together. If you separate the two steel plates, how can you weld them?”

Upon hearing Tsunade's analogy, Yagami Yoruichi immediately realized where the problem lay and slapped her forehead in frustration: "How could I have overlooked this! Thank you, Tsunade-sama, I'll try again."

With that, Yagami Yoruichi took a new fish and continued trying.

Chapter 48 The Weapon of Causality: Always Losing at Gambling

Although Tsunade had already pointed out the key points of Yoruichi Yagami's 'Regeneration Technique'.

However, truly mastering this ninjutsu is still a very difficult thing.

Of all the ninjutsu that Yagami Yoichi learned, only the 'Regeneration Technique' demands an abnormally high level of chakra control and requires extremely high concentration. Any slight mistake will lead to the failure of the ninjutsu.

Yoruichi Yagami believed that she already had a high level of control over chakra.

However, achieving control down to the 'micrometer level' is still an extremely demanding requirement.

Considering that this is only a B-rank ninjutsu in medical ninjutsu, and not even the most difficult one.

Yagami Yoruichi couldn't help but wonder, how insane are the requirements for chakra control for A-rank techniques like "Healing and Regeneration Technique" and "Hand Technique"?

What about the S-rank Hundred Healings Technique, Creation and Regeneration?

Does it mean we need to achieve nanometer-level, or even more precise chakra control accuracy?

Yagami Yoruichi was only curious for a moment before quickly clearing his mind and focusing on practicing the 'Regeneration Technique'.

Inside the living room, Kosuke Maruhoshi, Tsunade, and Shizune sat around the tea table.

"It's almost time."

Tsunade looked at the sky outside.

Winter was almost over, and it could barely be considered early spring, but it still got dark much earlier than in summer.
