The moment Tsunade took out the scroll, Ren's breathing nearly stopped.
At first glance, the old parchment looked completely ordinary. The edges were worn with age, and the surface carried faint traces of repeated use. Yet the instant Ren saw the words written across the front, his heartbeat thundered violently inside his chest.
Mystical Palm Technique.
An A-rank Medical Ninjutsu.
And more importantly to him…
It wasn't merely a technique.
It was a skin.
An Advanced Limited Skin.
For a split second, Ren nearly lost control of his expression.
If he could obtain the Mystical Palm Technique and gift it to the Healing Technique through the system, then he could instantly bypass the painful beginner stage that countless medical ninja spent years struggling through. Even if he wasn't perfect immediately, he would still enter the realm of advanced medical experts overnight.
That was the terrifying part of the system.
Others needed talent, time, and endless practice.
Ren only needed compatibility.
However—
He quickly forced himself to calm down.
His fingernails dug sharply into his palm beneath the table, using the sting of pain to steady his emotions.
No.
He absolutely couldn't act recklessly.
First, gifting an item through the system required consuming the original object. And the scroll Tsunade brought out clearly wasn't some cheap copy from the mission archives. Besides the cultivation method itself, there were many handwritten annotations inside, likely left behind by generations of Senju medical ninja.
That kind of inheritance was priceless.
Even if Tsunade trusted him enough to lend it to him, there was no way he could simply feed it to the system like an idiot. At the very least, he needed to secretly create a backup copy first.
Secondly…
There was the issue of common sense.
Even geniuses had to obey logic.
The Mystical Palm Technique was an A-rank Medical Ninjutsu. Its difficulty was leagues beyond ordinary Healing Techniques. Tsunade herself had already mentioned earlier that Shizune still hadn't mastered it despite training for over two years.
If Ren somehow learned it after glancing at the scroll once…
Forget suspicion.
Tsunade would probably drag him straight into a laboratory and start extracting blood samples immediately.
Maybe even cut him open for research.
The thought alone sent a chill down his spine.
Ren instantly became far more rational.
Slow and steady.
That was the correct path.
At that moment, Tsunade continued speaking calmly, seemingly unaware of the storm raging inside his mind. Or perhaps she had noticed his reaction and simply assumed he was overwhelmed by the prestige of an A-rank technique.
"Don't be nervous," Tsunade said casually while crossing her arms. "Although the Mystical Palm Technique is difficult, it isn't impossible for someone talented to learn it at your age. I mastered it myself when I was still a teenager."
Her amber eyes shifted toward Ren.
"Especially you, Yu. You might have the talent necessary for it."
"Um…"
Ren cautiously raised his hand.
"Lady Tsunade… how long did it take you to learn it back then?"
"Hm?"
Tsunade lifted her chin slightly.
A proud smile immediately appeared on her face.
"Me?"
"It took less than five months."
Confidence radiated from her voice.
"Of course, I was still young back then and didn't fully dedicate myself to training. If someone truly focused, perhaps three or four months would be enough."
Ren silently nodded.
Understood.
Four to five months.
That was the acceptable range.
Fast enough to appear talented.
Slow enough to remain believable.
Perfect.
Besides, the ordinary Healing Technique was already sufficient for most injuries. There was no need to expose himself too early. Even after mastering the Mystical Palm Technique through the system, he could simply pretend to still be studying it.
As long as he didn't reveal it in front of Tsunade, nobody would know.
Soon afterward, Tsunade formally began explaining the Mystical Palm Technique.
The atmosphere inside the room gradually became serious.
"This technique is fundamentally different from ordinary Healing Techniques," Tsunade explained while opening the scroll. "The standard Healing Technique stimulates the body's natural recovery ability. The Mystical Palm Technique, however, uses extremely dense chakra control to directly accelerate cellular regeneration."
She lightly tapped several sections of the scroll.
"The greatest difficulty lies in precision."
"If your chakra fluctuates even slightly, you may fail to heal the patient… or destroy their cells entirely."
Rin Nohara immediately took out paper and pen, rapidly writing notes with a focused expression.
Ren also began writing.
However, unlike Rin, who copied nearly everything word for word, Ren only recorded key concepts and important details.
Most of his attention remained entirely fixed on Tsunade herself.
Every sentence.
Every explanation.
Every subtle detail within her chakra theory.
He absorbed everything greedily.
The lecture lasted nearly an hour.
During that time, Tsunade explained the entire theoretical framework behind the Mystical Palm Technique, from chakra pathways to regeneration principles and emergency medical applications.
Several times, Rin's expression became dazed from information overload.
But Ren remained completely focused.
The room eventually fell silent.
Tsunade picked up her teacup and took a slow sip.
Rin lowered her head, repeatedly rereading her notes with a troubled expression.
Ren also glanced down at his own notes before quietly organizing the information inside his mind.
"How is it?" Tsunade suddenly asked.
Rin immediately stiffened.
"As expected of an A-rank technique…" she admitted honestly. "There are still many parts I don't fully understand."
Ren nodded as well.
"Yes. Especially the transition between chakra compression and regenerative stimulation."
As he spoke, he pointed toward several sections in his notes.
"What happens if the chakra density exceeds the tissue tolerance threshold?"
"And during emergency treatment, how do you stabilize regenerative frequency when the patient's chakra network is damaged?"
His questions were concise.
Sharp.
Practical.
Tsunade's eyes narrowed slightly.
The questions themselves revealed genuine experience.
The truth was that Ren's so-called "genius" wasn't entirely natural.
At least not completely.
The biggest reason Tsunade and Jiraiya valued him so highly was because of his terrifying compatibility with Healing Techniques.
Without the system's assistance, his medical knowledge would only be slightly above that of an average medical Chunin.
However—
Nobody understood Healing Techniques better than the Healing Technique itself.
During the process of increasing its favorability through countless treatments, Ren had accumulated enormous practical experience. He had already handled all kinds of injuries, illnesses, and chakra disorders.
Practice had forced improvement upon him.
As a result, his questions naturally sounded insightful.
Tsunade patiently answered every single one.
Even Rin's eyes gradually widened as she listened.
Because several of the questions Ren asked weren't things ordinary beginners would even think about.
After answering the final question, Tsunade quietly stared at him for several seconds.
Something thoughtful slowly appeared deep inside her amber eyes.
Finally—
She gently placed her teacup onto the wooden table.
Clink.
"Medical Ninjutsu is important," Tsunade said calmly.
"It saves lives."
Her gaze sharpened slightly.
"But in this world…"
"Knowing how to save people isn't enough."
"A medical ninja also needs the strength to protect themselves."
Her voice became colder.
"Sometimes, what you need isn't a shield."
"It's a spear capable of crushing an enemy's skull."
Ren's pupils contracted slightly.
Tsunade slowly stood up.
The loose sleeves of her yukata swayed gently as she turned toward the courtyard.
"I'll teach you another technique."
"Whether you can learn it or not depends entirely on yourselves."
"Follow me."
Rin hurriedly stood.
Ren silently followed behind them.
Outside, sunlight illuminated the spacious courtyard.
Decorative rocks and small trees filled the area, while near the center stood a massive granite boulder nearly half the height of a person.
Its rough surface looked incredibly solid.
Tsunade stopped in front of it.
Then—
She casually raised one finger.
Ren's heartbeat accelerated instantly.
A dangerous premonition rose inside him.
Sure enough—
"This technique," Tsunade said calmly, "requires perfect chakra control combined with explosive release."
"Watch carefully."
She didn't form hand seals.
Didn't gather momentum.
Didn't even take a stance.
Tsunade merely extended one slender finger and lightly poked the granite rock.
The next instant—
BOOOOOOM!!!
A deafening explosion erupted throughout the courtyard.
The entire granite boulder exploded from the inside.
Terrifying cracks spread instantly across the surface like a giant spiderweb before the massive stone completely shattered into countless fragments.
Dust and debris blasted violently into the air.
The ground trembled beneath their feet.
An invisible shockwave spread outward like a giant hammer strike.
Rin gasped sharply, covering her mouth in shock.
Her eyes widened so much they almost looked round.
The sheer destructive power completely exceeded her imagination.
Meanwhile, Tsunade herself remained perfectly still.
Not even her fingertip was injured.
Shizune, clearly already accustomed to scenes like this, merely stepped backward slightly and raised her sleeve to block the incoming dust.
Ren stared silently at the destroyed granite.
His scalp tingled.
This…
This was the true terror of Tsunade.
A monster capable of casually turning solid granite into dust with a single finger.
Then Tsunade finally spoke again.
"This technique…"
"Is called Superhuman Strength."
A faint smile appeared on her lips.
"Or as some people prefer to call it…"
"Cherry Blossom Impact."
