Concerned Tsunade
"The Yin Seal is a technique left behind by my grandmother. Originally, it was just a method for storing chakra. Later, I thought it could be combined with the Katsuyu Summoning Technique, and recently, I've had another idea…"
Creation Rebirth!
As soon as Kyōichi saw the concept, he immediately thought of Tsunade's signature technique.
It could simulate Hashirama Senju's ability to heal without hand seals.
Although it shortened one's lifespan, its power was undeniable.
This letter from Tsunade was likely sent after she learned about Kurenai's situation, asking for his opinion. From the letter, it was clear that Tsunade's Creation Rebirth was still in its early stages of development.
The information in the letter was vague, only outlining the general idea.
Kyōichi put the letter away.
Returning home, he immediately began writing a reply.
In the past, this letter would have been difficult to write because he only knew the effects of Creation Rebirth and had only a superficial understanding of its principles. But now, after studying numerous medical texts, he had the knowledge to respond.
Soon…
---
In the Land of Waterfalls, Tsunade sat on a rooftop, gazing at the serene village below. Her expression was a mix of confusion and determination.
At that moment, Shizune climbed up to join her.
"Tsunade-sama, have you been troubled lately?"
"Adult matters are none of a child's business. I'm not in debt anymore!"
Tsunade chuckled coldly.
In the past, her gambling habits often left her in the red, and she'd lose even her living expenses, leaving her at Shizune's mercy.
But now.
Hah!
She still gambled, but she didn't lose anymore!
If she lost money gambling, she'd make it back by catching cheaters.
Tsunade had her pride. In the past, she never used her ninja skills in gambling dens, unaware that cheating was even a thing.
Now, she gambled without using her senses but used them to catch cheaters.
And she'd caught quite a few!
Thanks to this, Tsunade had cleared many of her debts.
In fact.
Several gambling dens had even offered her a position to work for them, but Tsunade refused.
Gambling was a hobby; catching cheaters was for survival and cleaning up the gambling scene.
She couldn't tie herself down to one thing.
However.
Lately, Tsunade hadn't been feeling great.
"Is it because of what's happening in the Land of Earth?"
Shizune pouted.
As if she didn't know?
Every time Tsunade was in a bad mood, it was because something was bothering her, and it was likely related to that guy who resembled Nidaime, Kyōichi.
As for the reason, she could guess.
Iwagakure was growing stronger!
Recently, Ōnoki had been showing signs of wanting to take action, and many of the smaller villages nearby had already started pulling back their forces from the Land of Earth.
Despite leaving the village, Tsunade's heart was still somewhat tied to it.
"…"
Tsunade looked at her hands and sighed softly but didn't answer.
Before, she hadn't cared much about the village. There was no one left there she truly cared about. Even the old man, well, she'd be sad if he died, but not overly so.
But.
Ever since she learned that Iwa might make a move, she kept dreaming of that kid covered in blood.
It always woke her up in a cold sweat.
However.
Her hemophobia…
As she was lost in thought, a chakra fluctuation appeared nearby, and a Katsuyu clone emerged.
It carried a letter.
Tsunade immediately took it and opened it.
Shizune cautiously peeked over.
Tsunade noticed but didn't mind, reading the letter carefully.
She had told Kyōichi about the Yin Seal and her idea for Creation Rebirth, hoping he'd try to learn it. If he succeeded, it would be a life-saving technique on the battlefield.
As for the no-seal healing…
That was purely a personal dilemma, and she didn't know why she'd brought it up with Kyōichi.
But.
Unexpectedly, Kyōichi's reply actually addressed it, and he made some very insightful points.
"Tsunade-nee, you plan to use the Yin Seal to achieve no-seal healing, but there's a missing step. You need to first distribute the chakra from the Yin Seal throughout your body to achieve instant no-seal healing."
That's right!
After reading this, Tsunade was stunned.
In her excitement, she completely ignored the "Tsunade-nee" title.
She had been thinking about drawing chakra from the Yin Seal but had forgotten one crucial thing—if she waited until after being injured to transfer the chakra, it wouldn't truly be no-seal healing.
At best, it would be a no-seal version of the Mystical Palm Technique.
But.
If she could release the Yin Seal's chakra and evenly distribute it throughout her body at the same time, she could achieve true no-seal healing.
Of course.
This would require even greater chakra control.
Not only would the chakra need to be distributed evenly, but there could be no gaps. The benefits were also significant. If she could achieve this, Tsunade would essentially be able to use the Strength of a Hundred Technique at any time.
Exactly!
Kyōichi's idea was the Strength of a Hundred Technique.
He realized that Tsunade was only focusing on the Yin Seal and Creation Rebirth, missing the crucial bridge between them, so he pointed it out in his letter.
In Kyōichi's opinion, the Strength of a Hundred Technique was just as important as Creation Rebirth.
Creation Rebirth was powerful.
But it was a forbidden technique with significant drawbacks.
The Strength of a Hundred was different.
On its own, it wasn't particularly useful, but when combined with the Yin Seal and the Strength of a Hundred Technique, the results were incredibly powerful.
Tsunade was a smart woman.
She just hadn't thought of it, but once she understood, it wasn't difficult—
But many techniques were just one step away from greatness.
"Good kid!"
Tsunade held the letter, not knowing what to say.
In her letter, she had mentioned that Kyōichi should try to learn the Yin Seal.
Although it was difficult…
What if he succeeded?
But now.
It was the opposite. She had casually mentioned something, and Kyōichi had figured it out.
"Tsunade-sama?"
"It's nothing."
Tsunade pursed her lips and put the letter away.
She'd been schooled by the kid again!
Damn it!
Couldn't that kid let her teach him something for once?
Oh, right, he had asked about the Strength of a Hundred Technique.
But she suspected that if there had been a scroll for the Strength of a Hundred Technique, Kyōichi might not have even asked her for guidance.
And didn't he also know sword techniques?
His talent was too good!
Tsunade thought of her grand-uncle.
They were so similar.
This kid really was just like her grand-uncle!
Joy, sorrow.
A mix of emotions filled her heart.
"Shizune, do you want to go back to the village?"
"Huh?"
Shizune's eyes widened.
Tsunade wanted to go back?
What a joke!
She had been trying to convince Tsunade for years, but Tsunade had never budged.
And now, after just one meeting with Kyōichi and a few letters—most of which were about asking questions, not casual chats—Tsunade was ready to return.
"That kid's in trouble lately. Jiraiya isn't around, and there's no one to back him up. What if those old geezers try to scheme against him?"
Tsunade snorted.
Lifting the ban on forbidden techniques?
Those old geezers were no good, especially the one hiding in the shadows. He was the most despicable and had probably already set his sights on Kyōichi.
Rely on Orochimaru?
When it came to forbidden techniques, that guy couldn't be trusted.
Even though the Senju were gone, Kyōichi was still her grandfather's descendant. She couldn't let anyone bully him.
"The forbidden technique you mentioned earlier?"
"Yes, he means well. He wants to strengthen Konoha and reduce casualties in war, but some of those old guys…"
Tsunade sneered.
Then she glanced at Shizune and explained, "It's not that they're evil, but they're only concerned with their own little plots. They're narrow-minded, stubborn, and have a dark way of thinking. I've dealt with those geezers plenty in the past."
"Then, I'll go pack our things right away!"
Shizune understood.
Tsunade was eager to return, afraid that Kyōichi might be taken advantage of!
No problem, she'd handle it!
