Naruto said, "I use Shadow Clones to practice. After the Shadow Clone finishes learninf, the memories are transmitted back to the original body. Fifty Clones mean fifty memories."
"Moreover, these two Ninjutsu are very compatible with my conditions. I have Wind Chakra nature, and the Shadow Clone Technique is the Ninjutsu I am most proficient in."
"Vacuum Blade is an application of Wind Release, and Shuriken Shadow Clone Technique is an extended version of the Shadow Clone. I am familiar with the underlying logic of both techniques, so I picked them up quickly."
Jiraiya listened very carefully, and when he heard the last sentence, his brow twitched slightly.
This child was analyzing his own learning curve, breaking down the underlying logic of B-rank and A-rank Ninjutsu, and even pointing out why he learned so fast and where the speed came from.
Jiraiya looked at Naruto and said, "Naruto, your learning speed is very good. I am telling you very seriously, the Shadow Clone training method has risks."
"It accelerates progress by transmitting memories back when the Shadow Clones dissipate. This is theoretically feasible, but the massive mental impact generated by the Shadow Clones will all flood into the original body's brain at the same time."
"If accumulated too many times, it will cause irreversible mental damage. At best, memory degradation, and at worst, you will become an idiot."
Naruto nodded. "Got it, Pervy Sage. However, Pervy Sage, what are you going to teach me?"
"Idiot, don't give people nicknames randomly! Call me Toad Sage, or Jiraiya-sensei."
"Got it, Pervy Sage. So what are you going to teach me?"
Jiraiya looked at Naruto's matter-of-fact attitude and sighed.
He knew this nickname would probably follow him for the rest of his life.
Rubbing his temples, he decided not to waste his life on this battle that was destined to be lost, so he forced the topic back on track.
"You say first, is there anything you particularly want to learn?"
"Since your talent is so good, why don't you tell me what you think you need to improve the most right now?"
Naruto looked at Jiraiya with a serious expression. "There's a lot I need to learn. Are you willing to teach me everything?"
Jiraiya was amused by this retort. "Nonsense, I am one of the three Legendary Sannin. There are very few people in all of Konoha more versatile than me. Tell me, what type of Ninjutsu do you want to learn?"
"Fire Release, Water Release, Earth Release, or Lightning Release?"
"While I can't just teach you forbidden Ninjutsu, I can teach you any Ninjutsu up to A-Rank."
Naruto thought for a moment, then stated what he wanted to learn, "I want to learn Chakra nature transformation and how to train Chakra of other attributes."
"So far, my Chakra nature is only Wind Release, but I want to develop Chakra of other attributes."
"If there are any particularly powerful Ninjutsu, I can learn those too."
Naruto had an idea in mind: Chakra Fusion.
In the power system of the Ninja World, Chakra nature transformation is just the foundation. Moving up, one can fuse two different Chakra natures to obtain a Kekkei Genkai.
For example, Wood Release is a brand-new attribute born from simultaneously fusing Earth Release and Water Release Chakra.
However, in the entire Ninja World, apart from Hashirama himself and those who transplanted his cells, no one can use Wood Release.
Going further up is fusing three different Chakra natures to obtain a Kekkei Tōta.
Throughout the history of the Ninja World, the number of ninjas who can achieve this is extremely rare. The only Kekkei Tōta he knows of is Dust Release.
The Second Tsuchikage, Mū, fused Earth, Wind, and Fire Chakra to create Dust Release.
The power of Dust Release needs no explanation. It is a terrifying technique that can decompose any matter into an atomic state.
Standing at the very pinnacle of all Chakra attribute fusion systems is the Kekkei Mōra. This is the ultimate existence obtained by simultaneously fusing seven Chakra natures: Wind, Fire, Water, Earth, Lightning, plus Yin and Yang.
Only those at the level of Kaguya and the Sage of Six Paths truly master this power.
The Truth-Seeking Orb is a product of Kekkei Mōra. A single black sphere the size of a fist can easily crush any Ninjutsu or matter.
Normally, this path is impossible for any ninja.
Fusing two Chakra attributes requires maintaining the nature transformation of both attributes in a state of perfect equilibrium. If one side is even slightly more or less than the other, it will lead to failure or even backlash.
The difficulty of fusing three is not additive but exponential, which is why only Ōnoki in the current Ninja World has mastered it.
As for the five basic attributes plus Yin and Yang, that is the godly level.
But Naruto is different, he has Absolute Control.
Absolute Control allows for precise control over all of one's own matter and energy, from the density of Chakra flowing through every Chakra pathway to the contraction force of every muscle fiber.
What does this mean?
It means that the most difficult part of Chakra attribute fusion—precise ratio control—is not a threshold for him.
He doesn't need to rely on countless attempts to fumble for the ratio like an ordinary ninja. Absolute Control can precisely maintain the balance without the slightest deviation.
Of course, the difficulty of this goal is far from something that can be accomplished overnight.
First, he needs to master the nature transformation of all five basic attributes.
Currently, he only has Wind Release, and he still needs to develop Fire, Water, Earth, and Lightning.
Secondly, the nature transformation of each attribute itself requires a lot of time to master. It's not something you can do just by knowing the theory.
Furthermore, the nature transformation of Yin and Yang attributes is a higher-dimensional power system. Very few ninjas can touch this, and the training path is much more complex than the five attributes.
But the direction has already been set.
Ōnoki spent his whole life fusing three Chakra attributes to obtain Dust Release.
He has Absolute Control. He will not only fuse three but also five plus Yin and Yang, eventually forming the Kekkei Mōra. Only in this way will he have the strength to face the Ōtsutsuki Clan in the late stage.
