Originally, I only wanted to learn the basic Palm Healing Technique. I didn't expect to stumble upon something far more valuable.
Shigure left Konoha Hospital and made his way directly to his private training ground.
On the way,
he glanced down at the chakra forming effortlessly in his palm.
The Chakra Scalpel felt incredibly sharp in his hand—this technique was proving to be quite practical in combat.
And…
What if elemental chakra transformations were applied to it?
[Great Sage: Estimated calculation time—five hours. This technique demands highly refined chakra control. It is recommended the host improves chakra control to reduce calculation time.]
Five hours? That's not bad at all.
Still, I should finish developing the Cellular Regeneration Technique first.
Shigure deactivated both Breathing Techniques from his passive skill slots, along with Wind Release, clearing out four slots.
He filled all of them with the Palm Healing Technique.
Although it's a medical ninjutsu, when installed as a passive skill, it doesn't just strengthen the technique's healing capabilities—it also passively boosts chakra control and enhances Yang Release affinity.
Perfect.
This would make it easier to control chakra with precision.
Once this new medical ninjutsu was refined, he could fuse Chakra Scalpel and Escape Techniques directly.
"Great Sage, start with a complete deduction of the Palm Healing Technique."
The skill was then slotted into the passive system, set to auto-execute every thirty seconds.
It wasn't a long process.
All four passive skill slots were running the Palm Healing Technique in parallel.
Within an hour, Shigure could feel the growth—his mastery over the technique had increased at least tenfold.
Now, the precision of Shigure's medical ninjutsu rivaled even the most elite med-nin in Konoha.
There was still room for growth, sure—but it wasn't a priority anymore.
"Great Sage, initiate the fusion calculation."
[Great Sage: Fusion in progress… Estimated time: five hours.]
Previously, it would've taken three full days to calculate the fusion after learning Palm Healing,
but with his upgraded skill strength, the Great Sage's computing time dropped drastically.
With each passive execution, the time decreased further.
In the end, what was supposed to take five hours only took one.
[Calculation complete.]
[Congratulations. The host has obtained a new technique—Cellular Regeneration Technique.]
[Cellular Regeneration Technique: Rapidly metabolizes damaged tissue for near-instant recovery. Can also metabolize parts of one's body to heal others. Healing potency is dozens of times stronger than conventional medical ninjutsu.]
A complete success.
Shigure was more than satisfied with the results.
But even more important than the technique itself was what he discovered about Yang Release.
Yang Release isn't simply "life force"—it's the source of physical energy, separate from pure vitality.
Shigure could feel his Yang affinity growing stronger.
Still, even though his control over Yang Release improved, it didn't directly boost his life force.
It was an imperfection—but not a critical one.
Vitality could still be enhanced through raw physical training.
There was no need to rush.
After all, Taijutsu abilities could be installed into the passive slots at any time.
Reaching a level of immense vitality was only a matter of time.
After finalizing the new technique, Shigure decided to test it.
He sliced his arm with a kunai.
Then, without performing any hand signs, he activated the Cellular Regeneration Technique.
No seals. Pure thought-based activation.
This must've been due to the Great Sage's integration of the underlying jutsu principles.
It elevated the technique to a whole new class—something close to Supreme Ninjutsu.
He watched as the wounded skin dissolved into a faint mist—
then rapidly restructured, sealing the injury cleanly.
When the steam dispersed, the arm beneath was completely healed, as though it had never been injured at all.
The regeneration speed was astonishing—comparable to Naruto's self-healing through the power of the Nine-Tails.
If refined further, the technique's potential would be nearly limitless.
But—
There was one more surprise Shigure hadn't anticipated…
"There's no such thing as zero chakra consumption!"
At first, Shigure had assumed that medical ninjutsu would fall purely under elemental releases—so logically, as someone who could use elemental ninjutsu without chakra consumption, he believed he could also use healing techniques for free.
But reality was more nuanced.
The healing effect came primarily from the manipulation of Yang Release, rather than from a simple elemental transformation. While elemental chakra played a large part, Yang nature transformation was just as crucial.
In other words—this technique did consume chakra.
Fortunately, Shigure's current chakra reserves were formidable. Injuries like surface cuts or light wounds consumed next to nothing.
Even in the case of life-threatening injuries, he estimated he could still use the Cellular Regeneration Technique five or six times before chakra depletion.
And that's without any chakra recovery in between.
"Even if it's not completely without cost, the fact that the elemental portion of the technique is chakra-free is already a huge advantage," Shigure muttered.
"This gives me a reliable way to survive fatal injuries!"
"Now, on to the next phase—the fusion of Elemental Release with Chakra Scalpel."
[Great Sage: Beginning calculation.]
[Estimated time: three hours.]
Without hesitation, Shigure removed the Palm Healing Technique from his four passive skill slots and replaced them all with Chakra Scalpel.
Each iteration of the technique would auto-run every 50 seconds. Just like before, the Great Sage's calculation time would shorten with every activation.
After just under an hour of cycling—
[Calculation complete.]
[Congratulations. New technique acquired: Escape – Flowing Blade.]
[Escape – Flowing Blade: A stream of high-velocity chakra born from precise elemental transformation. With terrifying control, the stream flows with incredible speed, unleashing devastating cutting power.]
[Can be applied to projectiles, weapons, or even bare hands.]
The description alone gave Shigure chills.
"Another ninjutsu without hand signs—this is excellent."
He picked up a standard kunai and activated the Flowing Blade technique.
Instantly, a nearly invisible stream of high-speed chakra formed a thin film over the weapon.
It didn't look like much.
But when he lightly flicked the kunai at a nearby tree—
—the massive trunk was sliced clean in half.
"The precision… it's terrifying."
"If only I could fully master the Body Transformation Technique…"
If he could merge that technique with Flowing Blade, he could reshape his own body into a stream of cutting chakra—effectively becoming a living weapon.
Every inch of his body would become a blade.
"I can't do it—at least, not yet," he admitted.
"But… clones can."
That was the breakthrough.
If he could create a clone—one formed from flowing chakra—it wouldn't have the same physical restrictions.
A clone shaped entirely by chakra flow could naturally wield Flowing Blade through any part of its form.
It would become a lethal entity, capable of overwhelming close-range combat.
The idea alone made Shigure's heart pound.
"If I can pull this off… the clone's combat ability will be absolutely monstrous."
