Naruto: Start with three magatama and cultivate Kushina

"Actually, I've been in contact with Sage Mode for a long time, but I still haven't mastered it..." Jiraiya scratched his head and spoke.

"I don't know the Sage Mode you are talking about. Even if I want to teach you, I can't..." Tsunade also spoke at this time.

“Is there no Immortal Mode in the Wet Bone Forest? As one of the three holy places, it is impossible that there is no inheritance of immortal magic…” Liuyun frowned.

Tsunade was silent for a while after hearing this, then sighed and explained:

"Of course there is a fairy method inheritance, but if you want to learn the fairy method of the Wet Bone Forest, you must have an extremely abnormal amount of chakra. I can't meet this condition..."

"To date, my grandfather is the only one who has mastered the Wet Bone Forest Immortal Technique."

"The First Hokage? Have you mastered the Wet Bone Forest Sage Mode?" Orochimaru couldn't resist his curiosity and asked.

"Well! If you want to learn the Wet Bone Forest Immortal Technique, you need the consent of the Great Slug Immortal. I also want to learn it, but I don't have the talent of my grandfather. The Great Slug Immortal advised me to give up, saying that I can't learn it and it's too dangerous..."

"The Sage Mode of the Wet Bone Forest requires one's own chakra to forcibly suppress the natural energy."

Tsunade told the truth about her experience and also revealed an important piece of information.

"To learn the Sage Mode of Longdi Cave, you need to let the White Snake Sage bite you first. Then, the Sage will inject natural energy into your body, so that you can master the Sage Mode..."

Liuyun took the initiative to share information about the Sage Mode of Ryuchidong.

"Biting people to inject natural energy? What a strange way... The medium through which the Wet Bone Forest perceives natural energy is entirely dependent on the slugs that possess the body. It temporarily replaces the host to absorb natural energy." Tsunade continued to tell what she knew.

Seeing that Tsunade and Ryuun were both openly sharing information about the Holy Land, Jiraiya felt embarrassed to keep it a secret any longer:

"The temporary medium used by the Toad Clan to absorb natural energy is Toad oil, a specialty of Mount Myōboku. When Toad oil is applied to the body, natural energy will quickly flow into the human body."

"So, slug possession and toad oil, these media are actually temporary? They are simply to make people perceive natural energy faster?" Liuyun suddenly asked a question.

Liuyun felt that the reason why Longdidong's sage mode turned into a snake had a lot to do with the bite from the white-scaled snake.

Perhaps you can master the Sage Mode without being bitten, but the prerequisite is that you need to sense the natural energy on your own and absorb it into your body.

As a time traveler, Jiraiya actually knew most of the information, but he could not access Mount Myoboku, and without the help of toad oil, and without toads to help him keep watch and deal with out-of-control natural energy, he could not learn the Sage Mode even if he knew some tricks.

This kind of skill cannot be learned casually. Natural energy is too dangerous. Without the personal supervision of the immortals from the holy land, it is impossible to learn the immortal mode. If you try blindly, you can easily kill yourself.

"You could say that... the first major hurdle in Sage Mode is sensing natural energy. Without a medium, it is extremely difficult for a normal person to sense natural energy, and it is also difficult to experience the feeling of natural energy entering the body..."

Jiraiya explained why a medium was needed.

"But I think success or failure depends on the medium. The risks of the Sage Mode may also be brought about by the medium..." Liuyun expressed his opinion.

"What! This is impossible!!!" Jiraiya exclaimed. He felt that Liuyun's idea was too incredible.

"Nothing is impossible. The Sage Mode of Ryuchi Cave relies on the White Snake's 'poison injection'. Whether it succeeds or not, it will transform into a non-human form. The Sage Mode of Myoboku Mountain should be the same, right? I guess it's toad transformation..."

When Liuyun said this, Jiraiya's eyes widened instantly: "You guessed it right... The Myoboku Mountain Toad Oil can indeed cause frog transformation, or even petrification..."

"Then the question is, if we don't rely on these media, or even don't enter the three holy places, what kind of changes will happen to the human body after absorbing the natural energy from the outside world?"

"Is it a snake? A frog? A slug? Or will it not undergo any changes at all?"

Liuyun asked this question, which was also the question he cared about most.

The three of them were surprised when they heard this. They couldn't even learn the Sage Mode. They obviously couldn't answer Liuyun's question, or they had never thought about it at all.

In fact, the three great immortal techniques were not created for humans, and the so-called side effects are only aimed at humans.

The immortal magic that is truly suitable for humans may not have been created yet, or it may have existed before but the inheritance has been broken.

Liuyun learned from Jiraiya that without the help of a medium and the rich natural energy in the three holy places, it would take at least 20 to 30 years for an ordinary person with ordinary qualifications to sense natural energy.

Moreover, this requires years of meditation and self-cultivation to achieve this.

If you want to absorb the natural energy from the outside world into your body through mental power, it will take an ordinary person at least ten to eight years to do this.

Combining natural energy, spiritual energy and physical energy to describe the traditional fairy chakra, and condensing a sufficient amount of it will inevitably consume a lot of time and energy.

It is not impossible for a person to cultivate himself to become an immortal, but it is very likely that he will become old before he succeeds.

Once your body ages, you will fall into the dilemma of having sufficient natural energy and spiritual energy, but insufficient physical energy. You probably won't be able to synthesize much fairy chakra.

Therefore, if you cultivate immortality for your entire life, you will most likely end up with a miserable ending of accomplishing nothing...

The average life expectancy in the ninja world is less than fifty years old, and during wartime the average is even lower. Who would be willing to spend their entire life cultivating immortality?

It is understandable that no one has been able to create a magical method suitable for human practice, especially when chakra is so popular.

If it is easy to cultivate chakra power, who would bother to comprehend the immortal law?

Jiraiya's remarks made Liuyun very depressed. The difficulty level of mastering the Sage Mode without relying on a medium was too high.

His contracted holy land is Longdi Cave. If he wants to learn the immortal arts of Longdi Cave, he will be bitten. Being bitten means that he will more or less appear in the form of a snake and become a ghost that looks like neither a human nor a snake.

And this is only the case if he succeeds. If he fails, he will be eaten. Although given his relationship with the black dragon, he may not be eaten...

But the price of being bitten and turned into a snake (dragon) was something he couldn't accept, even though he coveted the power of the immortal...

He was reluctant to give up Ryuchi Cave and join Mount Myoboku. After all, he had finally subdued the powerful dragon, and things in the world could not always go as he wished. How could he sign Jiraiya's summoning contract just like that? How could he learn the magic of Mount Myoboku just because he wanted to?

"Forget it. Let's wait until the war is over before deciding whether to enter the cave to learn the magic..."

Liuyun temporarily suppressed the desire for power in his heart.
