A week later.
"It's finally starting to show some progress!"
Adam carefully sensed the kunai in his hand, which was imprinted with the Flying Thunder God Technique formula, and thought to himself:
"Genma's squad doesn't have anything left to teach. I'll ask the Fourth Hokage to see if I can advance further."
This past week, his main body had been consulting Phoenix, learning some basic spatial knowledge, while his Shadow Clones focused their energy on Apparition.
Now, he had finally gotten the hang of it and could sense the Flying Thunder God Technique formula.
Genma's three-person squad also told him that they had taught him everything they could, and from now on, he would have to rely on himself.
So he decided to activate his trump card and ask the Fourth Hokage, who could improve the Flying Thunder God Technique and truly make it shine, for guidance.
Even if Genma's three couldn't teach him now, it didn't mean the Fourth Hokage couldn't.
It's like when you go to learn from a master: if the Master Brothers who only learned superficial things can't teach you, it doesn't mean the master can't.
Loading the Naruto template, Adam's figure flickered and he appeared on Mount Myōboku.
"Naruto?"
As soon as he appeared on Mount Myōboku, Adam saw Naruto listening to Fukasaku's lecture by the Mount Myōboku toad oil waterfall.
His heart stirred, and he already had a guess.
"Adam, over here!"
At this moment, Naruto also saw Adam and quickly waved to him.
His figure flashed, and he appeared next to Naruto.
"Good afternoon, Lord Fukasaku."
After greeting Fukasaku, he turned his head to look at Naruto:
"Didn't you say yesterday that you were going to look for Sasuke? Why are you back on Mount Myōboku?"
"Pervy Sage said that with my current strength, I'm no match for Sasuke, so finding him would be useless.
So he brought me here this morning, saying that Lord Fukasaku could teach me a super powerful Ninjutsu that could defeat Sasuke.
If you want to go to Konoha, you can have Pervy Sage summon you; he'll be staying in Konoha's hospital to recover from his injuries for a while."
Naruto was a simple-minded person. He trusted Adam, so when Adam asked, he told him everything.
Adam's eyes darted around after hearing this:
"Oh, what kind of Ninjutsu is so powerful?"
"I don't know either. Lord Fukasaku was just about to explain when you arrived."
Naruto looked at Fukasaku, gesturing for him to continue quickly.
Adam also looked at Fukasaku:
"Lord Fukasaku, I wonder if I can listen with Naruto?"
"Of course, but if you want to learn, you'll have to wait until Naruto has learned it, because I can only teach one person at a time."
Fukasaku pondered for a moment, then nodded.
Sage Mode was Mount Myōboku's strongest secret technique. Normally, anyone who had signed a contract with the toad clan was qualified to learn this technique.
Adam's situation was special, but he was also considered to have signed a contract with Mount Myōboku.
Moreover, the toads of Mount Myōboku had indeed received many benefits from Adam, so not teaching him would seem too petty.
However, the Training of this Sage Art was very dangerous. If one was not careful and was swallowed by natural energy, they would turn into a stone toad. Many previous contractors had died while Training Sage Art.
In order to improve the success rate of Training Sage Art, he had to watch over them with full concentration, and if a problem arose and they were about to turn into a toad, he would immediately dispel the natural energy and start over.
At this stage, Naruto's situation was relatively dangerous, with the need to find Sasuke and face the Akatsuki Organization crisis, so Naruto naturally had to come first, and then he would help Adam learn.
"It's fine, I'm not in a hurry."
Adam sat down cross-legged with a smile, not at all angry.
As soon as Fukasaku said that, he knew that the super powerful Ninjutsu Naruto was referring to was Sage Mode.
Sage Mode is a technique where external natural energy is absorbed into the body, then mixed with one's own Chakra to achieve balance, forming a unique and very powerful Sage Art Chakra.
In Sage Mode, the power of one's Ninjutsu, Taijutsu, and Genjutsu will all receive a leap-like boost.
Furthermore, Sage Mode cultivated in different places would also have additional special abilities.
For example, Mount Myōboku's Sage Mode uses toad oil to assist in sensing natural energy. If it fails, one turns into a toad stone. If successful, it can further enhance attacks and perception.
Ryūchi Cave's Sage Mode involves the White Snake Sage injecting natural power with her poisonous fangs. If it fails, one turns into a snake and is eaten by the White Snake Sage. If successful, one can resonate with the environment using Sage Art Chakra and receive feedback.
As for Shikkotsu Forest, he wasn't clear, but looking at Senju Hashirama, it might be an additional boost to the body's recovery ability, as Shikkotsu Forest was originally primarily focused on healing.
"Good, then you and Naruto can learn the theory first."
Fukasaku nodded:
"Our normal Chakra synthesis is mental energy and physical energy. By combining them in a certain proportion, we can stably synthesize Chakra. What I'm going to teach you next is how to add natural energy on top of this foundation."
As Fukasaku explained, Adam's understanding of the principles of Sage Mode became clearer and clearer.
According to the history of this World that he knew, before the Ōtsutsuki appeared on this Planet, the energy used by the people here had always been natural energy.
Things like miko, onmyōji, samurai, and yokai all cultivated natural energy.
Unfortunately, Training natural energy required extremely high aptitude, and only a very small number of people could do it, perhaps only a few in an entire country.
Later, the Ōtsutsuki brought the God Tree, which absorbed and decomposed natural energy, forming a new energy called Chakra. The Sage of Six Paths, in order to allow ordinary people to use this energy for a better life,
began to spread this energy called Chakra and invented various Ninjutsu.
Due to the universality of Chakra energy, natural energy was phased out, and only some ancient traditions, such as the Three Great Sage Regions, still retained Training methods for natural energy.
However, many improvements were also made to adapt to the new environment.
In Adam's view, this was actually like the difference between Training immortals and practicing martial arts.
Martial artists Training internal energy, which comes from their own bodies, while Ninja extract the physical and mental energy within their own bodies to synthesize Chakra.
Cultivators of immortals, on the other hand, absorb spiritual energy from heaven and earth, and Sage Mode also absorbs external natural power.
How could someone who practices martial arts possibly defeat someone who cultivates immortals? The power is naturally different.
He wanted to learn Sage Mode, not only to learn how to absorb natural energy, but more importantly, to understand its principles in order to develop other new modes.
After all, he had many energy systems within him, and it wasn't necessarily limited to mixing in natural energy.
What would happen if he mixed "qi" into Chakra in a certain proportion?
What would happen if he mixed in magic power?
And the power of the Shinigami, or not just mixing one kind, but Chakra mixed with natural energy, then mixed with "qi", then mixed with magic power, then mixed with the power of the Shinigami – what kind of mode would that become?
