Chakra Refinement Technique 1.0

Facing Shizune's surprise, Genma laughed: "Shizune, do you know about the Yin-Yang Release?"

Yin-Yang Release?

Shizune was puzzled, then said: "I don't. Does it sound like a combination of Yin Release and Yang Release ninjutsu?"

Tsunade glanced at Genma again; this brat knew a bit too much.

The Ninja Academy would never teach knowledge like the Yin-Yang Release.

Noticing Tsunade's gaze, Genma explained casually: "I like to flip through materials at the library. I once saw a legend about the Sage of Six Paths in a very old book."

"Legend has it that the Sage of Six Paths used the Yin-Yang Release to create the Ninja World—that is, giving life to forms while simultaneously creating them."

"But legends are just legends. Let's return to a ninja's most basic ability: chakra."

Tsunade crossed her arms over her chest: "Are you trying to say that the Chakra Refinement Technique also belongs to the Yin-Yang Release?"

Shizune's eyes lit up upon hearing this: "That actually makes some sense."

Genma smiled: "That is indeed what I think, though it might be a bit of a stretch."

"But there is no doubt that Yang Release represents physical energy, and Yin Release represents spiritual energy."

Tsunade looked thoughtful.

Genma didn't continue, pulling the topic back by pointing at the scroll: "We have now opened up a broad path. Since the deepening of Yang Release nature transformation is related to the ratio, then by the same logic, the same applies to Yin Release."

Shizune said: "Genma, refining chakra at a ratio other than 1:1 is extremely difficult. I've tried for a long time and still can't do it."

Tsunade added: "Shizune is right. Don't get too happy too soon."

"This is even harder than practicing medical ninjutsu; it places very high demands on mental willpower and control."

Genma nodded: "That's normal. The existence of hand seals is meant to better execute techniques."

"But that doesn't change the fact that this is the most correct path for practicing Yin Release nature transformation and Yang Release nature transformation."

Tsunade acknowledged this point.

Genma asked curiously: "What ratio can Lady Tsunade's current Yang Release chakra achieve?"

Tsunade didn't hide it: "6:4, slightly higher than the level of the Mystical Palm Technique."

Physical energy 6, spiritual energy 4.

Genma speculated, is this level the standard for Creation Rebirth?

Or perhaps slightly inferior.

Then, was Senju Hashirama's seal-less self-healing at 7:3?

And was the Sage of Six Paths' Yang power at 8:2, or even higher at 9:1?

However, if even Tsunade could only manage 6:4, it showed that the further one went, the harder it became.

And Karin and Senju Hashirama were born stronger than this.

Not to mention the Sage of Six Paths.

Truly a world where bloodlines reign supreme.

Fortunately, I can modify the Setting Collection!

Genma wasn't panicked at all, praising her sincerely: "As expected of Lady Tsunade."

Tsunade didn't care for this emotional validation, her expression indifferent: "Take this scroll back and read it slowly. How have you mastered the Chakra Scalpel technique?"

As Genma put away the scroll, he replied: "I have mastered the basics. It is worthy of being an A-rank difficulty technique."

Shizune looked at him with admiration: "That's amazing!"

She was still quite a distance away from mastering the Chakra Scalpel technique.

Tsunade glanced at the slightly infatuated Shizune and secretly curled her lip: A little weaker than I was back then.

"You can practice the Mystical Palm Technique first, then perform the ratio adjustments. That will greatly reduce the difficulty."

Tsunade instructed with a blank expression.

Genma nodded obediently, but in his heart, he was thinking about the Setting Collection.

Refining Yang Release chakra is still refining chakra; in other words, when modifying the Chakra Refinement Technique, he could perfectly account for this aspect.

This way, there would be no need to spend extra Setting Value to add the content of Yang Release nature transformation.

After returning home from Tsunade's place, Genma couldn't wait to open the Setting Collection.

Without any hesitation, he chose to modify the Chakra Refinement Technique he had just added.

Chakra Refinement Technique 1.0: Capable of refining energy from any cell using spiritual energy to form chakra, and flexibly controlling the ratio of spiritual energy to cellular energy.

With only 2 points of Setting Value, Genma's modification was quite conservative.

The modification command was issued, and the Setting Collection updated immediately.

Success!

And the

Setting Value

has returned to zero once again.

"Let's first test the ratio adjustment between spiritual energy and physical energy..."

Taking a deep breath, Genma pressed his palms together, lowered his eyes, and began to refine chakra.

He first attempted a ratio of 5.5:4.5 for physical energy to spiritual energy, which corresponds to the nature transformation of

Yang Release

.

It was incredibly smooth, and he completed the chakra refinement without any obstacles.

Dispelling the newly refined chakra and letting it revert back into physical and spiritual energy, Genma began to refine chakra once more.

This time, the ratio was 6:4, which is the level of Tsunade.

The refinement was completed just as quickly, but Genma also sensed that it wasn't as smooth this time; the refined

Yang Release

chakra was noticeably less fluid to control.

Furthermore, the physical exertion increased significantly, nearly draining his stamina dry.

In other words, to achieve

Yang Release

chakra at this ratio, one requires sufficient spiritual energy to maintain the chakra's form, and the consumption rate skyrockets to ten times that of the normal ratio.

The corresponding physical toll is even greater.

"If I adjust the ratio any further, I'm afraid I won't be able to form chakra at all. It's not just a matter of control; my physical stamina is far from sufficient."

Genma had a premonition, and as he continued to experiment, it proved to be true.

"Beyond this point, the more lopsided the ratio, the more terrifying the physical stamina required... which means that powerful

Yang Release

nature transformation inevitably requires formidable life force to sustain."

Genma pondered to himself.

Indeed, a massive amount of chakra is the prerequisite for becoming a powerhouse.

"Let's try

Yin Release

nature transformation next."

Genma refined chakra again, this time increasing the ratio of spiritual energy directly to 6:4.

It was completed with extreme smoothness, and unlike the physical pressure he felt while refining

Yang Release

chakra earlier, he felt absolutely no mental strain.

"I can go further..."

Dispelling the chakra, Genma tried again.

This time, the ratio was 7:3.

It was still completed.

Moreover, Genma felt that his spiritual energy could still hold up; it was just his physical stamina that was lacking.

"Having been reborn through transmigration, my spiritual energy might be similar to an Uchiha Clan member who has undergone a spiritual mutation... Is this ratio of

Yin Release

chakra on par with a Three-Tomoe, or perhaps a Mangekyo?"

Genma carefully sensed the surging

Yin Release

chakra within his body; it was significantly colder than the

Yin Release

chakra from before.

After a moment of thought, he cast the

Sensory Ninjutsu

-

Thousand Branch Spirit Touch

.

Branches invisible to the naked eye grew out from his body, then rapidly expanded outward, continuously splitting into bifurcating twigs.

Genma clearly felt that the twigs condensed from an equal amount of chakra were far tougher than they had been in the past.

Consequently, he made the twigs even thinner to increase his sensory range.

"100 meters, my chakra isn't enough, that's the limit..."

Genma made an estimate; compared to before, the distance had increased by twofold.

Increasing the range by two times with the same amount of chakra, while also improving sensory precision—this is the astonishing boost brought about by the advancement in nature transformation.

Dispel the technique, Genma wanted to head out to test another ability, only to discover that it had grown dark.

"I'll wait until tomorrow."

Genma exhaled a breath of turbid air.

Tomorrow is Monday and he has school, but he will definitely use a

Shadow Clone

to attend class while his main body skips to train.

What would happen if he refined chakra from plant cells or animal cells?

Genma was filled with anticipation.

Also, developing genjutsu could be put on the agenda as well.
