Naruto: My setting is above yours.

Jingyin's eyes lit up: "That makes sense."

Genma smiled and said, "That's what I really think, even though it's a bit far-fetched."

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

Tsunade seemed to be deep in thought.

Xuanma didn't continue, but brought the topic back, pointing to the scroll: "Now we have opened up a broad road. Since the depth and proportion of the changes in the nature of Yang Dun are related, then by the same logic, the same applies to Yin Dun."

Shizune said, "Xuanma, it is extremely difficult to refine chakra in a non-1:1 ratio. I have tried for a long time but I still cannot do it."

Tsunade said, "Shizune is right, don't be too happy yet."

"This is more difficult than training medical ninjutsu, and it requires a high level of mental willpower and self-control."

Xuanma nodded: "That's normal. The seal exists precisely to facilitate the casting of spells."

"But this does not change the fact that this is the most correct path to cultivate Yin Release and Yang Release nature transformations."

Tsunade acknowledged this.

Genma asked curiously, "What proportion of Yang Release chakra can Lady Tsunade currently achieve?"

Tsunade didn't hide anything: "6:4, which is slightly better than the Palm Healing Technique."

Physical strength 6, mental strength 4.

Xuanma speculates that this level represents the level of creation and regeneration.

Or perhaps slightly inferior.

So, is Hashirama Senju's self-healing without hand seals 7:3?

Is the ratio of Yang energy of the Sage of Six Paths 8:2, or even higher, 9:1?

However, even with Tsunade's current skill level, she can only achieve a 6:4 score, which shows that it will become increasingly difficult as she progresses.

Karin, however, was naturally stronger than Hashirama Senju.

Not to mention the Sage of Six Paths.

This is truly a world where bloodlines reign supreme.

Luckily, I can change the settings!

Genma remained completely calm and sincerely praised, "As expected of Lady Tsunade."

Tsunade didn't care about such emotional value, her expression calm: "Take this scroll back and look at it slowly. How well have you mastered the Chakra Scalpel technique?"

As Xuanma put away the scroll, he replied, "I have already grasped it to a basic level. It is indeed worthy of being an A-level difficulty."

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

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

Tsunade glanced at Shizune, who was looking a little infatuated, and secretly pursed her lips: She's a little weaker than I was back then.

"You can practice the Palm Immortal Technique first, and then adjust the proportions. This will greatly reduce the difficulty."

Tsunade gave instructions with a blank expression.

Genma nodded obediently, but his mind was on the [Settings Collection].

Refining Yang Release chakra is also a form of chakra refinement, meaning that this aspect can be taken into account when modifying chakra refinement techniques.

Therefore, there is no need to spend additional settings to add the content of Yang Dun nature change.

……

Upon returning home from Tsunade's place, Genma eagerly opened the [Settings Collection].

Without any hesitation, he chose to modify the newly added chakra refining technique.

Chakra Refining Technique 1.0: It can extract energy from any cell to form chakra using spiritual power, and flexibly control the ratio of spiritual power to cellular power.

With only 2 settings, Xuanma's modifications were quite conservative.

Once the modification command is issued, the [Settings] will be updated immediately.

It worked!

The set value was reset to zero again.

"Let's try adjusting the ratio of mental and physical strength first..."

Taking a deep breath, Genma clasped his hands together and lowered his eyes to refine his chakra.

He first tried a ratio of physical strength to mental strength of 5.5:4.5, which is the change of Yang Dun nature.

It was incredibly smooth, and the chakra extraction was completed without any hindrance.

Genma dispersed the chakra he had just refined, transforming it back into physical and mental energy, and then refined the chakra once more.

This time it's 6:4, which is Tsunade's level.

The refining process was completed quickly, but Genma also felt that it wasn't as smooth this time, and the refined Yang Release chakra was noticeably less controllable.

Moreover, it consumes a lot of physical strength, almost draining me dry.

In other words, to achieve this ratio of Yang Release chakra, sufficient mental strength is needed to maintain the chakra form, and its consumption will increase tenfold compared to the normal ratio.

The corresponding physical exertion is even greater.

"If the proportions are adjusted again, I'm afraid I won't be able to generate chakra. It's not just a matter of control; my stamina is far from sufficient."

Xuanma had a premonition, and after trying again, it turned out to be true.

"Further on, the ratios become disparate, and the required physical strength becomes increasingly terrifying... In other words, powerful Yang Release nature transformations inevitably require formidable vitality to sustain them."

Xuanma pondered to himself.

Indeed, a large amount of chakra is a prerequisite for strength.

"Let's try the Yin-style nature transformation again."

Genma refined his chakra once more, this time increasing the ratio of spiritual power to 6:4.

It was completed very smoothly, and unlike the physical pressure I felt when refining Yang Release chakra earlier, I didn't feel any mental pressure at all.

"We can continue..."

Genma dispersed his chakra and tried again.

The ratio this time is 7:3.

It was completed.

Moreover, Xuanma felt that his mental strength was still holding up, but his physical strength was not enough.

"I was reborn, and my spiritual power is probably similar to that of the Uchiha who underwent a spiritual mutation... Is this proportion of Yin Release chakra on par with the Uchiha's three-tomoe Sharingan, or is it the Mangekyou Sharingan?"

Genma carefully sensed the surging Yin Release chakra within his body, which was noticeably colder than the previous Yin Release chakra.

After thinking for a moment, he used his sensory ninjutsu - Thousand Branches Spirit Touch.

Invisible branches grew from his body and then rapidly expanded outwards, constantly branching out.

Genma clearly felt that the branches formed from the same amount of chakra were far more resilient than before.

So he made the branches thinner to increase the sensing distance.

"100 meters, not enough chakra, that's my limit..."

Xuanma estimated that the distance had increased by two times compared to before.

The same amount of chakra doubles the distance, and the perception accuracy is also improved. This is the amazing increase brought about by the nature change.

After dispelling the spell, Genma wanted to go out and try out another ability, but found that it was already dark.

"Let's wait until tomorrow."

Xuanma exhaled a breath of foul air.

He'll be going to school tomorrow, Monday, but he'll definitely use a shadow clone to attend class while his real body skips class to cultivate.

What would happen if we extracted chakra from plant cells and animal cells?

Xuanma was full of anticipation.

Furthermore, the development of illusion magic can also be put on the agenda.

Chapter 11 Chakra Mode

The following day, Genma and Kakashi skipped class on time as usual.

Kakashi was studying Lightning Release, while Genma went into a lush forest and plopped down on the grass to try out a new chakra refining technique.

His senses expanded, and Xuanma lowered his eyes to perceive them carefully.

A moment later, he sensed the energy contained within the plant cells of the weeds scattered all over the ground.

Grab it and refine it!

But it failed!

The energy contained in the cells of a weed is too little.

Xuanma opened his eyes, thought for a moment, then got up and leaped onto a branch of a large tree.

Place your right palm on the trunk of the big tree and let your senses spread out.

Compared to those weeds, the cells of these towering trees contain abundant energy, especially now that it is springtime and everything is growing.

Refining Chakra!

This time, there was no doubt that it was a success.

The refined chakra flowed from the tree's body into Genma's body through his palm.

He was very careful; he didn't consume all the cellular energy of the entire tree in one go, but only extracted 5%.

Genma roughly estimated that the chakra extracted from these 5% was only 1% of his own chakra.

Not much, but not a small amount either.

How many such large trees are there in Konoha and the Land of Fire?
