In the depths of Ryuichi Cave.
Yeruashi sat quietly on his knees, and the natural energy that was in Ryuichi Cave gradually entered his body.
It had been ten days since he began training the sage mode of Ryuichi Cave.
But this is the time of the outside world, for Yeruashi, who was training in a state of quintuple time acceleration, fifty days had passed.
The practice of Sage Mode is really difficult, especially for Yeruashi, whose total chakra volume just reached the level of Kage.
It took about twenty days to feel the natural energy around him, and this is still a particularly favorable environment, as Ryuichi Cave is very rich in natural energy.
Buzz!
Yeruashi's body, which was kneeling, began to deform and possibly change already.
His body grew rapidly in size, his clothes stretched and began to tear. Regarding Yeruashi's exposed skin, it can be seen that he is no longer human, stone scales have appeared instead.
Whoosh!
In the next moment, Yeruashi abruptly opened his eyes, a flash of light passed through his eyes, and his body immediately stopped changing and then quickly returned to its normal state.
"It's still too hard to control it... no, it's hard enough to maintain the right proportion..."
Yeruashi muttered.
The change he had just obtained in his body is a transformation occurred due to the instability of the natural energy in his body.
Just like the Sage Art of Mount Myboku, the Sage Art of Ryuichi Cave possessed the same risks, that is, once the natural energy goes out of control in his body, it will undergo sudden mutations until it completely merges with nature, or in other words, until it turns into stone.
So compared to the Sage Art of Myboku Mountain, the Sage Art of Ryuichi Cave are just as difficult to learn, first of all, it is not easy to pass the three tests of Ryuichi Cave, which must be completed individually, which is why Rin, the Jinchuriki of the Sanbi, was sent elsewhere.
Faced with the three Ryuichi Cave tests, normal ninjas could barely pass and most would end up dead.
In the first test, due to the rapid absorption of chakra, it was impossible to pass the test unless one possessed chakra at the level of a Kage or higher and one also had to possess chakra at the level of a Kage or higher to pass the next two tests.
But even after passing the test of the three sage snakes and meeting the Sage White Snake, one only obtains the Sage mode practice method.
Practice with the three sage snakes?
Given their nature, it will not be so easy to get their recognition.
Since you have not received their recognition, it remains only to train on your own, from scratch. Once a normal ninja, who does not have the ability to turn back time, has some trouble during training and it is not uncommon to die on the spot.
A large number of stone statues of snakes can be found in Ryuichi Cave, far more than a few dozen.
In fact, Mount Myboku is not much different in this respect from Ryuichi Cave. If there were an ordinary ninja in Naruto's place, who has no connection with Mount Myboku, then the sage toad would not direct his training, and in the case of independent training, the probability of failure increases many times over. This is where the large number of stone statues of Mount Myboku comes from.
Yeruashi did not look for three sage snakes to help him with the training.
Because there was no point.
With the ability to turn back time, Yeruashi doesn't need the help of outsiders to dissipate the natural energy in his out-of-control body.
"Aside from the difference in the operation paths of the three great immortal arts, there should also be a certain difference in the ration of chakra and natural energy..."
Yeruashi muttered and returned to training.
He will not completely master the Ryuichi Cave Sage Mode, but would limit himself to the basic level. After all, Yeruashi's main goal is not to master the Sage Art, but to develop the Sage Body.
After the natural energy has become uncontrollable several times in a row.
In Yeruashi's eyes shone the light, his body expanded a little, but did not become uncontrollable and began to petrify, only the appearance was quite strange.
Yeruashi lowered his head, respecting the puddle below.
In the reflection, he saw a face with snake-like features and shadows around the eyes, resembling Orochimaru's appearance.
"This is the initial mode of the Sage Art..."
Yeruashi stood up and could feel that his body seemed softer than before, capable of movements that were flexible beyond human limits.
"It's not good to have a softer body."
Yeruashi made a few movements and muttered thoughtfully, "The Mount Myboku Sage mode makes the body firmer and stiffer, while the Ryuichi Cave Sage mode is softer and more flexible, although the stiffness suits me better in this case... but the ideal Sage Body should allow me to be in a normal state."
"As I thought, to develop the Sage Body, I need to balance the Sage Art of Mount Myboku and Ryuichi Cave.... I guess I also need the Sage Art of Shikkotsu Forest."
After a few seconds of reflection, Yeruashi began to evaluate other changes in his body.
Being in the Basic Mode of the Sage Art, Yeruashi could feel that his perception had increased countless times.
But this did not involve hearing or seeing.
His ability to perceive life had increased.
At this point, Yeruashi's perception could envelop almost half of Ryuichi Cave. He perceived a large number of snakes of various sizes living here, and he could also understand where the three sage Snakes and the Sage White Snake were located, as the life vibrations they emitted stood out strongly from all the other snakes
"He did that?"
"Surely there is a power that even I cannot discern."
When Yeruashi entered the initial stage Sage Mode, the Sage White Snake exhaled puffs of smoke and looked in his direction.
The White Snake Sage, of course, possesses the highest level of skill in the Sage art among all the inhabitants of the region, and his perception is able to cover the entire Ryuichi Cave.
"That human is really a monster..."
At that moment, Ichikishimahime opened her eyes and also looked in Yeruashi's direction. She involuntarily shuddered as she recalled their encounter.
In the last hundred years, there had not been a single person who had mastered the Sage Art on his own, without his guidance!
At first glance, it may seem that anyone who passes the test can begin to practice the Sage Art of Ryuichi Cave, but in reality, its spread is strictly controlled by the Sage White Snake. Only when you have received true recognition from the locals can you begin to fully practice the Sage Art of Ryuichi Cave.
But Yeruashi...
He was able to master the Ryuichi Cave Sage Mode by practicing alone and without the help of any of them!
This is the first such case since his birth hundreds of years ago.
"Monster..."
Tagorihime and Tagitsuhime also looked towards Yeruashi and whispered softly.
Previously, they had conspired not to help Yeruashi, hoping that his Sage Mode practice would get out of hand and then they could play with him, but suddenly, Yeruashi was able to master Sage Mode on his own, without any instruction !
"As expected, a very powerful perception. All life signs within a one mile radius won't be able to escape from me, and creatures with chakra are perceived even more obvious..."
Yeruashi smirked.
