Uchiha Kiyoshi was also affected by Yun's memory about Paper Release.

Uchiha Kiyoshi was extremely surprised that Paper Release was the product of incomplete fusion of earth and water.

"So this kind of thing can still happen during the integration process?"

Is it possible to form a new escape technique even if the fusion fails? Xiaonan is out of luck.

It's probably because the fusion method or the proportions were wrong, but somehow a balance was achieved, eventually forming Paper Escape.

However, this reminded Uchiha Kiyoshi.

In the development of Mudun, perhaps the control of vitality is a key part.

Well, the cloud is doing well.

As for urging me to make gold fingers quickly? Haha, do you think this is wholesale?

A structure as small as the eye is not easy to modify.

Speaking of eyes, Uchiha Kiyoshi thought of his Sharingan again.

Back on the island, Uchiha cleared away the experiments of developing wood escape and modifying his eyes. He still had other time to practice or study other things.

Among them, the perfection of Yangyuan Gong is one aspect.

Yangyuan Gong, a fundamental method developed step by step by Uchiha Kiyoshi from the body-nurturing technique.

Uchiha Kiyoshi's most important secret technique.

After Uchiha Kiyoshi successfully sensed natural energy, he came up with the idea of ​​improving and perfecting the Yanggen Gong again.

It was finally completed a few days ago.

It eliminates various tedious details such as extraction from food, extracts mild natural energy directly from food, and then smoothly obtains body energy through its own property changes.

Make the complex simple.

Although it is not the simplest, it is still an improvement.

The efficiency of Yang Yuan Gong has also been greatly improved due to this improvement, and Uchiha Kiyoshi's chakra recovery speed has doubled again.

In the previous battle with the Three-Tails, Earth and Stone had already achieved a chakra recovery speed of 300 calories per second. This was still a clone, and the main body had reached a recovery speed of nearly 500 calories even faster. Now Uchiha Kiyoshi can achieve a recovery speed of 1 second.

Restored one thousand calories of chakra!

Moreover, after cutting out some tedious steps and having extra energy, Uchiha Kiyoshi was even able to fight when using his Yang Yuan Gong at full power.

These are all improvements in Yanggen Gong and have little to do with Uchiha Kiyoshi's Sharingan.

What is really closely related to Uchiha Kiyoshi's Sharingan is Uchiha Kiyoshi's next operation.

The gentle natural energy in food that has been "tamed" layer by layer in the food chain can be directly "refined" by Uchiha Kiyoshi's Yangyuan Gong. So, can chakra be fused into chakra by directly absorbing natural energy from the environment?

Or can it be said that after refining, it is directly the magic chakra?

With a trying mentality, Uchiha Kiyoshi introduced a ray of natural energy into his Yangyuan Gong.

During this process, Uchiha Kiyoshi naturally guarded every corner, so there was no need to worry about natural energy escaping into the body.

Instead of starting the so-called refining directly, Uchiha Kiyoshi continued to dilute this bit of natural energy with mild natural energy extracted from food. Finally, Uchiha Kiyoshi, who felt almost the same, started refining the mixed natural energy.

It passes through chakra with special properties, and then merges with spiritual energy.

Chakra was successfully fused.

However, there is a hint of irritability in some of the chakra.

That violent aura also felt familiar to Uchiha Kiyoshi, just like... the chakra of a tailed beast?

Uchiha Kiyoshi can control this part of chakra, but his control over it is far inferior to normal chakra.

However, Uchiha Kiyoshi still controlled the movement of this chakra in his body, hoping to use the human body to filter out the violent aura.

However, this disappointed Uchiha Kiyoshi.

The body has no filtering effect on natural energy or it is not obvious.

This violent aura of chakra did not disappear just because it was circulating in the body.

"Oh. Why can't it work?

It’s obvious that the natural energy in food has been transformed so gently.”

Uchiha Kiyoshi was unwilling to give in, and by some strange combination of circumstances, he activated this chakra again, this time throughout his whole body.

Before, Uchiha Kiyoshi only circulated this chakra in the internal organs and limbs of the body, but this time it was different, the brain also joined in.

The violent aura did not disappear because of this, but Uchiha Kiyoshi noticed another point.

His Sharingan reacted.

These violent auras seemed to stimulate the Sharingan.

This is a stimulation that Uchiha Kiyoshi Sharingan has not experienced since he reached the peak of the three magatama.

Natural energy has the ability to stimulate the Sharingan and even promote its upgrade!

This discovery made Uchiha Kiyoshi ecstatic.

The kaleidoscope is here!

Unfortunately, this stimulation is not enough and more research is needed.

Therefore, Uchiha Kiyoshi added another research project.

The effect of natural energy on the Sharingan.

From the principle to the magnitude of the stimulation, we should try our best to study it as thoroughly as possible.

Is there any other evidence that natural energy stimulates the Sharingan? In addition to stimulating the Sharingan to upgrade, does it have other effects, such as supplementing pupil power?

This is also an important point.

If you use a kaleidoscope too much, you will become blind.

Since natural energy has an effect on the Sharingan, it is natural to think of the side effects of the Mangekyo Sharingan.

"Speaking of the side effects of kaleidoscope, there are two known solutions. One is to upgrade to the eternal kaleidoscope, and the other is to transplant Hashirama cells."

"Hashirama cells can replenish pupil power!"

What about natural energy?

Can I replenish my eyesight?

Is it related to the intercolumn cells?

Perhaps this study and the study of intercolumn cells should be conducted together.

It's easy to say that it's stimulating. The irritable aura itself is a negative effect. It can also be regarded as emotion. It may satisfy the stimulation needed to upgrade the Sharingan.

What Uchiha Kiyoshi wants to study is whether the intensity of this violent aura is the basis for stimulating the Sharingan eye.

Is it necessary to open a kaleidoscope with a strong stimulus in one step, or is it like boiling a frog in warm water and slowly opening up the bottleneck?

These are all the contents of Uchiha Kiyoshi's research.

"Oh, it's so difficult for me."

Uchiha Kiyoshi let out an overwhelmed sigh.

"The system of cultivating immortals is still waiting to be established by myself. There are also wood escape, eye modification, and even subsequent research on elimination of blood successors and even blood successor snares, research on yin and yang escape, there are too many!

Now there is another study on the effect of natural energy on the Sharingan."

Uchiha Kiyoshi was trapped in research and couldn't extricate himself, but the ninja world did not stop changing.

The friction between Konoha and Kumogakure Village continues, and the Rain Country Yu Ninja Village continues to suppress the Akatsuki organization...

The ninja world is not peaceful after all.

"The middle genin will go first. Nagato, Konan, Yun, and Kurosui will block the other jounin-level ninjas. Leave the two elite jounin to me."

Facing the sudden appearance of the Rain Ninja Village, Yahiko issued an order as the leader of the organization.

Two elite jounin, ten jounin!

The Rain Ninja Village also got angry.

Yahiko had just entered the elite jounin level for the first time. At this time, he was one against two, and he soon fell into a disadvantage. However, depending on the situation, his life would not be in danger in the short term.

Of the ten remaining jounin, Nagato and Konan were able to deal with three of them each, but they managed to persevere.

Yun and Heishui are one against two.

Yun is okay, but Heishui is a bit more difficult.

He is neither a genius like Yahiko, nor a person like Yun who has the combat experience of the original body. After all, he has the combat experience of the elite Jonin level, and the shadow clone can secretly open the Sharingan in the sealed space...

It's different with Heishui. His strength is really at the bottom among jonins.

Even though his strength has increased after joining the Akatsuki organization and gained several powerful ninjutsu, it still cannot reach the level of one against two.

Seeing this, Yun gritted his teeth and took on an enemy for Heishui.
To be continued...
