Seeing the conversation turn entirely toward Kiyohane’s side, Obito immediately panicked and hurried to explain.
“Hey, hey!
That’s not what I meant!
I was just saying… shuriken are too ordinary!”
“Obito!”
Rin quickly called out to him.
Seeing that, Obito fumbled through an explanation, but unfortunately, the more he tried, the worse it got.
Kakashi could not even be bothered to comment anymore.
He simply shook his head and continued practicing his shuriken throws.
Kiyohane did not say anything else either.
He picked up a shuriken and began throwing according to the teacher’s instructions.
With the Hatake-style Shurikenjutsu trait he had just obtained from Kakashi, Kiyohane could clearly feel that his throwing motion had become much less tiring.
The way his wrist exerted force had been silently optimized.
Saving stamina means saving chakra.
Kiyohane thought to himself.
If he could conserve more stamina, it would also benefit him when casting ninjutsu later.
According to the official databooks, when physical energy and spiritual energy mixed, they formed stamina.
And stamina could then be converted into chakra.
This kind of chakra was neutral in nature.
For example, Naruto’s most basic Rasengan used a mass of neutral chakra rotating at high speed.
If one wanted neutral chakra to undergo a nature transformation, it had to pass through the heart, the largest part of the chakra pathway system.
The chakra pathway system carried chakra throughout the body.
Every cell in the human body was connected to it.
Only because of it could shinobi refine chakra at any time and gather chakra wherever they wanted.
…
The day’s lessons soon came to an end.
Kiyohane packed up his ninja tool pouch, said goodbye to Kakashi and Rin Nohara, and walked home alone.
When he pushed open the door, Tsunade was sprawled across the sofa in an extremely bold posture.
She wore a loose green coat, and her gray sleeveless top outlined her full figure.
Her long, fair legs were casually crossed and resting near the edge of the tea table.
Without even lifting her eyelids, she saw Kiyohane return and lazily moved her fingers.
“Kiyohane… get me a bottle of water from the fridge…”
Kiyohane silently changed his shoes.
He had long since grown used to Tsunade’s complete lack of proper image.
He walked into the kitchen and took a bottle of cold water from the refrigerator.
When he came back and handed it to Tsunade, his gaze inevitably passed over a certain bottomless valley.
When Kiyohane gazed into the abyss, the abyss gazed back at him.
“You didn’t come home last night,” Kiyohane said, clutching his forehead and turning off his auto-aim.
“Oh, I went to pick up Shizune.”
Tsunade screwed the cap back onto the bottle and jerked her chin toward the kitchen.
Kiyohane followed her gaze and only then noticed someone else in the kitchen.
A black-haired little girl about his age was walking out with a plate of sliced fruit.
“Kiyohane, you’re back.”
“Shizune.”
Kiyohane greeted Shizune as well.
The two of them were on fairly good terms.
Shizune was an orphan.
She had originally followed her uncle, Dan Kato, and after Dan’s death, Tsunade took pity on her and accepted her as a disciple.
In that sense, her situation was actually quite similar to Kiyohane’s.
“Didn’t Shizune need to attend the entrance ceremony yesterday?” Kiyohane asked curiously.
He had not heard the chunin instructor call Shizune’s name yesterday, so he had not helped pick up her file.
He simply had not seen her.
“Yesterday happened to be the anniversary of her parents’ deaths, so she couldn’t make it.
I only brought her back today.”
Tsunade waved a hand and pointed at the file on the table.
“Don’t worry.
I informed the Ninja Academy in advance.
Besides, she only missed one day of lessons.
She can make it up later.”
Kiyohane nodded, understanding the reason.
“So when are you teaching me medical ninjutsu?”
Kiyohane brought the topic back around.
“You only taught me the theoretical basics before.
You haven’t formally taught me any medical ninjutsu yet.”
Hearing him ask, Tsunade grew a little more serious.
At Kiyohane’s age, he really could begin formally learning medical ninjutsu.
As for Kiyohane’s chakra natures, she had specifically tested them before.
He possessed five chakra natures: Yin, Yang, Water, Fire, and Earth.
Tsunade also had five chakra natures, though she lacked Yin and had Lightning instead.
The reason Tsunade had tested him was to see whether Kiyohane possessed Yang Release.
Having that chakra nature meant he possessed the most important innate requirement for learning medical ninjutsu.
“Shizune, come here for a moment.”
Once Shizune dried her hands and hurried over, Tsunade gestured for the two of them to sit properly in front of her.
“Starting today, I’ll teach you formal medical ninjutsu.”
As Tsunade spoke, she opened her right palm.
A soft green chakra emerged from her palm, as if she were holding a glow of green light.
“This is a D-rank medical ninjutsu called Chakra Healing Technique.
It’s the most basic kind.”
“The chakra used for medical ninjutsu must be Yang Release chakra, because Yang Release’s nature is to grant vitality.
Only Yang Release chakra can stimulate cell regeneration.”
“If you force chakra of another nature into an injured person’s body, not only will it fail to heal the wound, it may cause secondary damage instead.”
Tsunade continued her explanation.
“So the first step in learning medical ninjutsu is to refine neutral chakra from within your body, then transform it into Yang Release chakra.”
Kiyohane listened quietly.
This step was essentially nature transformation, like turning chakra into burning flame or flowing water.
Changing its shape, on the other hand, was called shape transformation.
Those two things basically determined all ninjutsu.
“Try it yourselves first,” Tsunade said.
Shizune nodded, closed her eyes, and lightly brought her hands together in front of her.
On the other side, Kiyohane activated his crimson Sharingan, planning to see if he could copy it.
The copying ability of a one-tomoe Sharingan was limited.
The stronger the Sharingan, the stronger its insight.
The easier it was to see through the details of chakra flow, the easier it became to learn another person’s jutsu.
The reverse was also true.
“The Sharingan, huh.”
Tsunade glanced at Kiyohane’s eyes.
She did not have much prejudice against the Uchiha clan, so she could calmly accept someone like Kiyohane.
[Collectible trait detected: Wound-Healing Talent.]
[E-rank Trait: Wound-Healing Talent.]
[Effect: Healing effects on traumatic injuries increase by an additional 10%.]
[Synthesis: Two evolution routes available.]
[Route One: Add E-rank Trait: Simple Bandaging + E-rank Trait: Basic Hemostasis to synthesize D-rank Trait: Skilled Hemostasis.]
[Route Two: Add E-rank Trait: Natural Prodigy + E-rank Trait: Exceptional Memory to synthesize D-rank Trait: Innate Medical Body.]
Kiyohane glanced at the notification that appeared, then returned his attention to his palm.
He refined neutral chakra from every cell in his body and, following the key points Tsunade had just explained, attempted to perform Yang Release nature transformation.
The process was smoother than expected.
Perhaps the solo-training efficiency boost from Genius’s Solitude was taking effect.
Kiyohane felt his chakra control was more effortless than usual.
With the assistance of the Sharingan as well, results quickly appeared.
