Chapter 639

Ryuchi Cave.

Deep inside.

Feng was sitting cross-legged quietly, and the Nature's Chakra that was dissipating in the Ryuchi Cave was gradually flowing into his body.

Ten days had passed since he started cultivating the Immortal Technique.

These ten days were the time that had passed in the outside world, but for him, who was in the state of Quintuple Speed, 50 days had passed.

Practicing the Sage Mode was indeed very difficult, especially since the total amount of Chakra he had was only at the level of a Kage, so it was even more difficult.

It took him about 20 days to feel the existence of Nature's Chakra, and this was in the special environment of the Ryuchi Cave, where Nature's Chakra was extremely abundant.

Zizi!

Feng Ye, who was sitting cross-legged, suddenly experienced a change in his body.

His body began to expand strangely, and his clothes suddenly rose up, revealing the skin underneath. It could be seen that his skin was no longer in the shape of a human, but had turned into petrified scales.

Whoosh!

In the next moment, Feng opened his eyes, and a light flashed in his eyes. His body that was changing suddenly froze, and then quickly returned to its normal state.

"It's still very difficult to control … No, it should be said that it's very difficult to maintain that proportion …"

Feng murmured.

The change just now was caused by the Nature's Chakra going out of control.

Just like the Sage Technique of Mount Myoboku, the Sage Technique of Ryuchi Cave was also dangerous. Once the Nature's Chakra went out of control, it would turn into a giant petrified snake, and completely integrate with nature.

So compared to the Sage Technique of Mount Myoboku, the Sage Technique of Ryuchi Cave is just as difficult. First of all, it's not easy to pass the three Snake Sage's test. The test of the three Snake Sage is completely dependent on the person. For example, Lin was directly sent out with Sanubi Kifu.

And what he was facing was a checkpoint that almost no ordinary ninja could pass.

In the test of absorbing chakra, it's impossible to open the stone door without Chakra above Kage level, and it's also impossible to fight against the three Snake Sage.

And even if he passed the test of the three Snake Sage and came to the ancestor of the Ryuchi Cave, the White Snake Sage, he can only get the Sage Mode's training method.

He wanted three Snake Immortals to spar with him?

Let's find a way to get their approval first!

If he can't get their approval, then he can only practice by himself, and practicing by himself, ordinary ninjas don't have the ability to turn back time, and once there is a problem, it will be a huge trouble, and it's normal to die on the spot. At least there are more than dozens of giant snake statues nearby.

In fact, Mount Myoboku is almost the same, Naruto belongs to the 'Backdoor' category, and when ordinary people enter Mount Myoboku, how can they let Fukasaku Fukasaku be a teacher or a sparring partner, they practice by themselves, and if they don't practice well, they will turn into stone statues.

Feng didn't bother to catch Ichibashi, Shimahime, and the others to practice with him.

Because it's meaningless.

With the ability to turn back time, he doesn't need Ichibashi, Shimahime, and the others to help him when he loses control of the natural chakra, he can solve it by himself.

"In addition to the difference in the path of operation, there should also be a certain difference in the ratio of chakra and natural chakra …"

Feng Ye muttered to himself before starting to cultivate again.

He doesn't intend to completely master the Ryuchi Cave's Sage Mode, he just needs to master it to a certain degree, because his goal isn't to master the Sage Mode, but to cultivate the Sage Body.

Finally!

After losing control several times in a row.

Feng suddenly opened his eyes, his body slightly inflated, but he didn't lose control and petrify, but his current appearance is a little funny.

Feng looked down at the puddle below, he can see that his face is slightly showing signs of turning into a snake, and there are deep eyeshadows, similar to Orochimaru's state.

"This is the initial stage of Sage Transformation …"

Feng stood up, he can feel that his body seems to be softer than before, and he can make some movements that exceed the limits of a human's flexibility.

"It's not good for your body to become soft."

Feng twisted his body, and muttered, "Mount Myoboku's Sage Technique is to become hard, and Ryuchi Cave's Sage Technique is to become soft, although hard is much better than soft … hmm, a perfect Sage Body should be the most normal state.

"As I expected, in order to obtain the Sage Body, I need to cultivate both Ryuchi Cave and Mount Myoboku's Sage Technique in order to neutralize them … I guess I'll also need the Shikkotsu Forest's Sage Technique as the neutralizing agent."

After thinking for a few seconds, Feng checked the other changes in his body.

Under this Elementary Celestial Transformation, or rather, Elementary Celestial Transformation, Feng could feel that his senses had become countless times more active than before.

It wasn't that his hearing and sight were more active.

Instead, it was a different level of perception towards life.

Right now, as he stood here, his senses could cover almost half of Ryuchi Cave. He could sense the large number of giant snakes living in the depths of Ryuchi Cave, and he could also sense the locations of the White Snake Immortal and the three Snake Immortals. He could also sense the aura that was different from that of other giant snakes.

"Did I succeed?"

"As expected, there's a power that even I can't see through."

While Feng Ye was undergoing Elementary Celestial Transformation, the White Snake Immortal breathed out a mouthful of smoke and glanced in Feng Ye's direction.

As the White Snake Immortal, its level of Celestial Technique was naturally the highest here. It could cover the entire Ryuchi Cave and perceive everything that happened in the Ryuchi Cave, including Feng Ye's Celestial Technique.

"That human is really a monster …"

Ichimarajima Hime also opened her eyes and glanced in Feng Ye's direction. Thinking about the time when Feng Ye's Chakra exploded, she couldn't help but shiver.

In the past hundreds of years, it can be said that no one has ever become a Celestial without the personal guidance and help of the three Snake Immortals!

It seems that anyone can learn Celestial Technique as long as they pass the test, but in fact, Celestial Technique is firmly controlled by the White Snake Immortal. Only those who are truly recognized by the Snake Immortal can practice Dragon Cave Celestial Technique.

And Feng Ye …

He practiced alone, without any help from the three of them, but he still succeeded in practicing Dragon Cave Celestial Technique!

This is the first time in hundreds of years since they were born!

"Monster."

Tanshin Kamimi and Kumizu Hime also silently muttered.

Originally, they had come to an agreement that none of them would give Feng Ye any pointers. They were worried that if Feng Ye lost control of his Immortal Mode, they would be able to toy with him as they pleased. However, they didn't expect that Feng Ye would successfully learn the Celestial Technique on his own without any guidance from the three of them!

"My perception is indeed very strong. Any signs of life within a kilometer can't escape my perception, and the target with Chakra is even more accurate …"

Feng Ye showed a trace of satisfaction.
