On Yuta's side, while constantly combining natural energy with Chakra to form Senjutsu Chakra, he was also carefully experiencing the effects of natural energy.
In this world, Chakra is divided into seven Chakra natures: water, fire, earth, wind, lightning, yin, and yang.
A Chakra, which originally has no attributes, can give birth to these Nature Transformations, which have different applications.
The source of Chakra in this world should be traced to the Sage of Six Paths.
In the past, Sage of Six Paths had established Ninshu and gave Chakra to others.
If we go even further back, the source of Chakra is Kaguya, who had eaten the fruit of the god tree.
And how did the fruit of the god tree come?
The god tree is rooted in this world, constantly absorbing the natural energy, and it eventually bears a fruit.
That is to say, Chakra is actually derived from natural energy if you seek it from the source.
However, the difference between the two is obvious.
Chakra is more stable and easier to use by ninjas.
For example, Chakra can be used to perform ninjutsu of seven kinds of nature transformations.
But natural energy is much more difficult to utilize.
Some human beings and the sage regions use it by combining Chakra with natural energy to form Senjutsu Chakra.
"Perhaps if there was no god tree of the Ōtsutsuki clan, this world would have been like those Chinese novels, where people cultivate?"
Yuta had this idea in his mind when he had extracted the Senjutsu Chakra.
The more he thought about it, the more it made sense.
Without the involvement of the Ōtsutsuki clan, the route of the aborigines in this world would have been to develop technologies that directly utilize natural energy.
The natural energy in this world is a bit similar to the spiritual energy in those cultivation worlds.
"However, in this case, talent will become even more important. The gap in strength between people will be even greater."
Yuta felt the natural energy that kept entering his body.
For ordinary people, when natural energy enters their body, there is no doubt that they will die.
Even a person with a talent for this will find it very dangerous.
In comparison, Chakra is much gentler.
Even if it is injected into the body of ordinary people, it will not have any effect.
Shaking his head and dispelling a bunch of thoughts in his mind, Yuta began to think about one important thing.
"Since Chakra is derived from natural energy, maybe natural energy can also perform Nature Transformation similar to Chakra?"
It seems to make sense.
In Ryūchi Cave, there seems to be a trick called Sage Art: Inorganic Reincarnation!
In the original story, Kabuto had once performed it.
This is a kind of ninjutsu that can give life to inanimate inorganic things and control them.
With this ninjutsu, Kabuto made the surrounding environment seem alive.
It's kind of like the effect of Yang release.
The function of Yang release is to give life to inanimate matter.
"Natural energy should also be able to carry out complex nature transformations such as yin and yang release."
Yuta deduced so in his heart and tried it immediately.
Controlling the natural Chakra in his body, he carried out the corresponding Nature Transformation according to yin and yang release.
"It seems feasible!"
Yuta couldn't help but light up.
Natural energy, according to his will, successfully carried out the corresponding Nature Transformation.
The change of Yin and the change of Yang can be done.
Without hesitation, Yuta manipulated the yin-yang Chakra Nature Transformation and poured into his eyes.
The awakening of Rinnegan requires sufficient yin and yang.
Both are needed in enough quality and quantity.
He has the blood of Indra and Asura, but he couldn't awaken the Rinnegan immediately because the amount of Yin and Yang Chakra was not enough, and it takes time to accumulate.
That's why Madara didn't awaken the Rinnegan until his deathbed.
And the power of yin and yang derived from natural energy has no problem on the qualitative level.
Ultimately, natural energy is of a higher rank than Chakra.
Maybe he can awaken the Rinnegan today.
"Tsk! I knew that I should have come to practice senjutsu earlier, but I didn't expect it to have such an effect."
Yuta sighed with emotion.
Then without hesitation, he absorbed the natural energy with all his strength.
At this moment!
The whole Ryūchi Cave was shaken.
The scattered natural energy in Ryūchi Cave began to gather towards Yuta frantically.
Some giant snakes who were not proficient in Senjutsu found that the Senjutsu Chakra in their body was leaving.
The Senjutsu Chakra then decomposed into natural energy.
"White Snake Sage, won't you stop him?"
Beside the White Snake Sage, Ichikishimahime looked at Yuta tremblingly and said.
This guy's way of absorbing natural energy id too terrifying, right?!
Even the White Snake Sage doesn't absorb natural energy in such a way.
"If we don't stop him, the natural energy of our Ryūchi Cave may take a long time to recover!"
Tagitsuhime felt the gathering of natural energy in the air and wanted to cry.
Ryūchi Cave would be heartbroken after the loss of so much natural energy in one go.
Although natural energy can be recovered, the recovery process is very slow and can only be done slowly.
"Hold on."
White Snake Sage was not in a good mood.
While looking at Yuta, her eyes were full of depression.
This kid!
If the natural energy absorbed by him is converted into Senjutsu Chakra, it will be comparable to the Senjutsu Chakra accumulated in her body.
The natural energy of Ryūchi Cave is limited.
Even if it is the three sage regions, each place can only support one existence like her.
This is why she has always coveted Mount Myōboku.
Once Mount Myōboku is occupied, she can absorb Mount Myōboku's natural energy and increase her strength.
Originally, she thought of providing some help to Yuta, and help him learn Sage Mode, and then let him kill the old toad.
She didn't expect this kid to be so exaggerated.
He was clearly learning Sage Mode, but he absorbed so much natural energy and even awakened the Rinnegan.
However, the White Snake Sage knew that Yuta was now at a critical stage and could not be interrupted.
Anyway, she has already invested, so she can't disturb him at this critical time, right?
Just invest till the end!
Some more time passed.
"Stop stop!"
The White Snake Sage watched the purple Rinnegan in Yuta's eyes take shape.
Her huge tail was beating wildly on the ground, causing the ground to vibrate one after another.
"That's it! Ryūchi Cave can't support you anymore."
The Rinnegan has already been awakened and he still wants to suck more natural energy!
If it's not your own territory, you won't feel bad, right?!
Yuta wasn't quite sure what to do, but he still stopped.
He raised his hand and performed a water release to make a mirror, and looked into his eyes.
The original Sharingan had now turned completely purple, with circles of lines.
Rinnegan!
Rinnegan, which he was longing for had finally awakened.
For the first time, Yuta began to experience the pupil technique he had acquired—The World!
"This pupil technique that stops time. Hmm... When using this pupil technique, should I shout Za Warudo?"
Yuta suddenly thought of Dio in his mind.
