Seeing the momentum shift toward Sosuke, Obito panicked and hurriedly explained:
“Hey, hey, that’s not what I meant.
I was just saying…
Shuriken are just too ordinary!”
“Obito!”
Rin Nohara said quickly.
Seeing this, Obito scrambled to explain, but unfortunately, he only made things worse.
Kakashi couldn’t even be bothered to retort; he just shook his head and continued practicing his shuriken throwing.
Sosuke didn’t say anything further either.
He picked up a shuriken and began throwing practice according to the teacher’s instructions.
With the bonus from the Hatake-style Shurikenjutsu trait he had just acquired from Kakashi, Sosuke felt that his movements were indeed much more effortless, and the way his wrist exerted force had been invisibly optimized.
‘Saving stamina means saving Chakra,’ Sosuke thought to himself.
If he could save more stamina, it would be beneficial for releasing Ninjutsu later.
According to the official guidebook, the less tired you are, the longer you live.
And stamina can be converted into Chakra.
For example, Naruto’s most basic “Rasengan” uses a sphere of non-elemental Chakra rotating at high speed.
If one wants to change the nature of non-elemental Chakra, it must pass through the heart, the largest meridian system.
The meridian system is the channel that carries Chakra, and every cell in the human body has a connection to the meridian system.
With it, one can extract Chakra at any time and gather it wherever desired.
Soon, the day’s lessons came to an end.
Sosuke packed his ninja tool pouch, said goodbye to Kakashi and Rin Nohara, and walked home alone.
Pushing open the door, Tsunade was already sprawled on the sofa in an extremely carefree posture.
She was wearing a loose green coat, a grey sleeveless top outlining her voluptuous silhouette, and her long, fair legs were casually crossed over the edge of the coffee table.
She didn’t even lift her eyelids.
Seeing Sosuke return, she just moved her fingers lazily:
“Sosuke…
go to the fridge and get me a bottle of water…”
Sosuke silently changed his shoes.
He was already used to Tsunade’s lack of decorum.
He walked to the kitchen and took a bottle of ice water from the fridge.
When he returned to hand it to Tsunade, his gaze inevitably passed over a certain unfathomable cleavage.
When Sosuke gazed into the abyss, the abyss also gazed back at him.
Tsunade knocked Sosuke on the forehead.
Sosuke rubbed his forehead and disabled his auto-aim.
“Oh, I went to pick up Shizune.”
Tsunade tightened the bottle cap and gestured with her chin toward the kitchen.
Sosuke followed her gaze and only then noticed there was another person in the kitchen.
A young black-haired girl of similar age to him was walking out carrying a plate of cut fruit.
“Sosuke, you’re back.”
“Shizune.”
Sosuke also greeted Shizune; the two of them had a pretty good relationship.
Shizune was an orphan, so she had followed her uncle, Kato Dan.
After Kato Dan died, Tsunade took her in as a disciple.
So her situation was actually very similar to Sosuke’s.
“Did Shizune not need to attend the entrance ceremony yesterday?”
Sosuke asked curiously.
He hadn’t heard the Chunin instructor call Shizune’s name yesterday, and he hadn’t helped carry any files because he hadn’t seen her at all.
“Yesterday happened to be the anniversary of her parents’ death, so she didn’t make it.”
Tsunade waved her hand and pointed to the files on the table:
“Don’t worry, I already notified the Ninja Academy in advance, and it’s only one day of missed lessons.
She can just make it up later.”
Sosuke nodded, understanding the reason.
“Then when will you teach me medical arts?”
Sosuke brought the topic back.
“We only covered the theoretical foundations before; I haven’t taught any formal Medical Ninjutsu yet.”
Hearing his question, Tsunade became a bit more serious.
At Sosuke’s age, it was indeed time to start learning Medical Ninjutsu formally.
She had specifically tested Sosuke’s Chakra natures before.
They were Yin, Yang, Water, Fire, and Earth—a total of five Chakra natures.
Tsunade also had five Chakra natures, except she lacked Yin and instead had Lightning.
The test was because Tsunade wanted to know if Sosuke possessed the Yang nature.
Having this Chakra nature meant possessing the most critical innate condition for learning Medical Ninjutsu.
“Shizune, come here for a moment.”
Tsunade called toward the kitchen.
After Shizune dried her hands and trotted over, Tsunade signaled for both of them to sit in front of her.
As Tsunade spoke, she spread out her right palm.
A mass of gentle green Chakra emerged from her palm, as if holding a green light.
“This is a D-rank Medical Ninjutsu called ‘Chakra Healing Technique’, the most basic kind.”
“The Chakra used in Medical Ninjutsu must be Yang Release Chakra, because the nature of Yang Release is to bestow life force; only Yang Release Chakra can stimulate cell regeneration.”
“If you forcibly inject Chakra of other natures into a wounded person’s body, not only will it fail to heal the injury, but it will actually cause secondary damage.”
Tsunade explained.
“So, the first step in learning Medical Ninjutsu is to extract non-elemental Chakra from within your body and then convert it into Yang Release Chakra.”
Sosuke listened quietly.
This step is essentially “Nature Transformation”, like burning flames, flowing water, and so on.
And if one changes its form, that is what is called “Shape Transformation”.
These two points basically determine all Ninjutsu.
“You two try it first.”
Tsunade said.
Shizune nodded, closed her eyes, and lightly clasped her hands in front of her chest.
On the other side, Sosuke also activated his scarlet Sharingan, intending to see if he could copy it.
A one-tomoe Sharingan has limited copying ability.
The stronger the Sharingan, the stronger the insight, and the easier it is to see through the details of Chakra flow, thereby learning other people’s techniques, and vice versa.
“Sharingan, huh.”
Tsunade glanced at Sosuke’s Sharingan.
She didn’t have any prejudice against the Uchiha Clan, so she could calmly accept the existence of someone like Sosuke.
[Collectible trait detected: Healing Talent]
[E-rank trait: Healing Talent]
[Effect: Healing effectiveness for trauma-type injuries is increased by an additional 10%.]
[Synthesis: Two evolutionary routes]
[Route 1: Add ‘E-rank trait Simple Bandaging’ + ‘E-rank trait Basic Hemostasis’, can synthesize D-rank trait: Masterful Hemostasis.]
[Route 2: Add ‘E-rank trait Gifted Player’ + ‘E-rank trait Superb Memory’, can synthesize D-rank trait: Innate Medical Body.]
Sosuke scanned the prompt that appeared and brought his attention back to his palm.
He extracted non-elemental Chakra from his body and, following the essentials Tsunade had just mentioned, attempted to perform the nature transformation of Yang Release.
This process was smoother than he had imagined.
Perhaps the bonus to solo training efficiency brought by the previously acquired ‘Genius’s Loneliness’ trait was playing a role; Sosuke felt that his Chakra control was even more adept than usual.
Combined with the assistance of the Sharingan, he soon achieved results.
