Learning Medical Ninjutsu

Seeing the tide turn toward Qingyu, Obito immediately panicked and hurriedly explained:

"Hey, hey, that's not what I meant! I just meant... shuriken are such ordinary things!"

"Obito!"

Rin Nohara quickly said.

Seeing this, Obito flailed as he tried to explain himself, but only made things worse.

Kakashi could not even be bothered to tease him. He merely shook his head and continued practicing his shuriken throws.

Qingyu said nothing more. He picked up a shuriken and began throwing practice according to the teacher's instructions.

With the Hatake Style Shurikenjutsu trait he had just obtained from Kakashi, Qingyu found that his throwing motions truly required much less effort. The way he exerted force through his wrist had been subtly optimized.

"Saving stamina means saving chakra."

Qingyu thought to himself.

Being able to conserve more stamina would also benefit him when casting ninjutsu later.

According to the databook, physical energy and spiritual energy combined to form what was known as stamina.

Stamina could then be converted into chakra.

This chakra was attribute-less. For example, Naruto's most basic Rasengan used a rapidly spinning mass of attribute-less chakra.

If one wanted attribute-less chakra to undergo a transformation, it had to pass through the body's largest meridian system: the heart.

The meridian system served as the channels that carried chakra. Every cell in the human body was connected to it.

Only with it could one extract chakra at any time and gather it wherever it was needed.

Soon, the day's lessons came to an end.

Qingyu packed up his ninja tool pouch, said goodbye to Kakashi and Rin Nohara, and headed home alone.

When he pushed open the front door, Tsunade was sprawled across the sofa in an exceptionally unrestrained pose.

She wore a loose green coat, while a gray sleeveless shirt outlined her voluptuous figure. Her long, fair legs were casually crossed and resting against the edge of the coffee table.

She did not even lift her eyelids. Seeing Qingyu return, she merely lazily moved a finger.

"Qingyu... get me a bottle of water from the fridge..."

Qingyu silently changed his shoes. He had already grown used to Tsunade's complete lack of decorum.

He walked into the kitchen and took a bottle of ice water from the refrigerator.

When he returned and handed it to Tsunade, his gaze inevitably passed over a certain unfathomable ravine.

When Qingyu stared into the abyss, the abyss stared back at him.

Tsunade flicked Qingyu on the forehead.

"You didn't come home last night."

Qingyu covered his forehead and turned off his auto-aim.

"Oh, I went to pick up Shizune."

Tsunade twisted on the bottle cap and jerked her chin toward the kitchen.

Following her gaze, Qingyu finally noticed that there was someone else in the kitchen.

A black-haired little girl about his age was walking out with a plate of sliced fruit.

"Qingyu, you're back."

"Shizune."

Qingyu greeted Shizune as well. The two of them got along fairly well.

Shizune was an orphan, so she had lived with her uncle, Dan Katō. After Dan Katō died, Tsunade took pity on her and accepted her as a disciple.

So, in truth, her circumstances were quite similar to Qingyu's.

"Didn't Shizune have to attend the enrollment ceremony yesterday?"

Qingyu asked curiously.

He had not heard the chunin instructor call Shizune's name yesterday, so he had not helped carry her file either, because he had not seen her at all.

"Yesterday happened to be the anniversary of her parents' death, so she missed it. I only picked her up today."

Tsunade waved a hand and pointed at the file on the table.

"Don't worry. I notified the Ninja Academy in advance. She only missed one day of classes, so she can make it up later."

Qingyu nodded, understanding the reason.

"Then when will you teach me medical techniques?"

Qingyu brought the topic back around.

"You only taught me the theoretical basics before. You haven't formally taught me Medical Ninjutsu yet."

At his question, Tsunade grew a little more serious.

At Qingyu's age, he truly could begin formally studying Medical Ninjutsu.

Tsunade had previously tested Qingyu's chakra attributes specifically.

They were yin, yang, water, fire, and earth—a total of five chakra attributes.

Tsunade likewise possessed five chakra attributes, except she lacked yin and had lightning instead.

The test had been meant to determine whether Qingyu possessed a yang attribute.

Having that chakra attribute meant he had the most crucial innate prerequisite for learning Medical Ninjutsu.

"Shizune, come here for a moment."

Tsunade called toward the kitchen.

After Shizune dried her hands and trotted over, Tsunade motioned for the two of them to sit before her.

"Starting today, I'll teach you formal Medical Ninjutsu."

As Tsunade spoke, she spread open her right palm.

A soft green mass of chakra emerged from her palm, as though it were holding up a green glow.

"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 Yang Release's nature is to grant vitality. Only Yang Release chakra can stimulate cellular regeneration."

"If you forcibly inject chakra of another attribute into an injured person's body, not only will it fail to heal them, it will instead cause secondary damage."

Tsunade explained.

"So, the first step in learning Medical Ninjutsu is to extract attribute-less chakra from within your body, then transform it into Yang Release chakra."

Qingyu listened quietly.

This step was actually called a "nature transformation," like burning flames or flowing water.

Changing its form, meanwhile, was what was known as a "shape transformation."

Those two principles essentially determined all ninjutsu.

"You two try it first."

Tsunade said.

Shizune nodded, closed her eyes, and lightly brought her hands together before her.

Meanwhile, Qingyu activated his crimson Sharingan, intending to see whether he could copy it.

The copying ability of a One-Tomoe Sharingan was limited.

The stronger the Sharingan, the stronger its perception. The easier it was to discern the details of chakra flow, the easier it became to learn another person's technique, and vice versa.

"The Sharingan, huh."

Tsunade glanced at Qingyu's Sharingan.

She did not hold any prejudice against the Uchiha clan, so she could calmly accept someone like Qingyu.

[Detectable collectible trait: Healing Talent]

[E-rank trait: Healing Talent]

[Effect: Healing effectiveness for traumatic injuries increases by an additional 10%.]

[Synthesis: Two evolution routes]

[First route: Add "E-rank trait: Basic Bandaging" + "E-rank trait: Basic Hemostasis" to synthesize the D-rank trait: Masterful Hemostasis.]

[Second route: Add "E-rank trait: Talented Player" + "E-rank trait: Superb Memory" to synthesize the D-rank trait: Innate Medical Saint Body.]

Qingyu glanced at the prompt that appeared, then returned his attention to his palm.

He extracted attribute-less chakra from every cell in his body and, following the method Tsunade had just explained, attempted a Yang Release nature transformation.

The process went more smoothly than he had imagined.

Perhaps the bonus to solo training efficiency granted by Solitude of a Genius was taking effect. Qingyu found his chakra control more responsive than usual.

With the Sharingan's assistance, he quickly achieved results.
