That can't be right?
That is the Ninjutsu created by the Fourth Hokage, Minato Namikaze.
Everyone was shocked.
Because... after Black-Framed Naruto said that...
Hey~!
Don't tell me, don't tell me, it really sounds like the truth!
Inside Shinigami's stomach.
Minato Namikaze watched this scene and silently closed his eyes.
"As expected of my son."
"It's just a pity."
"A pity about what?" Nine-Tails Yin Half-Body asked.
"It's a pity that I can't teach him either the Flying Thunder God or the Rasengan."
"Judging by the development in the black frame world, Naruto definitely won't accept Jiraiya-sensei, and if Jiraiya-sensei dares to spout nonsense, Naruto absolutely wouldn't mind sending him on his way."
"In that case, there aren't many ways left for him to acquire them. Kakashi is one."
That's right.
Kakashi knows Rasengan.
After all, his Chidori was developed based on the Rasengan.
Chidori was only perfected after he transplanted Obito's Sharingan, which provided a qualitative leap in dynamic vision.
After strengthening Chidori with Lightning Release Chakra Nature Transformation, it was able to cut lightning, turning it into Raikiri.
Of course, the most important thing is that Kakashi had the Sharingan.
And during the Third Great Ninja War, the Sharingan given to him by Obito made him famous throughout the Ninja World: Copy Ninja, Kakashi Hatake.
Coupled with having consulted Minato Namikaze more than once, it was normal for him to understand the method for practicing Rasengan.
If, at this point in time, news came that Jiraiya had died outside the Village, the task of teaching the Rasengan would definitely fall to Kakashi.
This wouldn't be Kakashi showing favoritism.
The implications involved go without saying.
As for how exactly to teach it... referring to the training for the Rasenshuriken would provide the answer.
This is the correct way to unlock Naruto's talent, not by instilling a bunch of nonsensical ideologies filled with the Will of Fire and the Great Toad Sage's prophecies.
In the Ninja World, given Naruto's identity, if you say you want him to live happily, then what about before? What were you doing then?
Knowing there was a powerful organization targeting Jinchuriki, you took him out to train, only to tell him to live happily?
Oh, right, right, right, if he's not strong enough and gets captured to have his Chakra drained, then he'll be happy~
Clearly having the ability to change everything, yet ignoring it to search for the child of prophecy.
Only after Hiruzen Sarutobi died did he remember Minato Namikaze's last wish?
He simply didn't want to stay in the Village and wanted to continue searching for the child of prophecy, so he brought Tsunade back to be Hokage, and incidentally took Naruto on a journey to help him control the Nine-Tailed Chakra, adding high-level fighting strength to the Village.
If he truly cared, he could have guarded Naruto or taken him along in his childhood, wouldn't things have been simpler?
He didn't know? The Nine-Tails Rampage (Jinchuriki must die), the death of Konoha's Fourth Hokage—how could he not know?
He was probably busy peeping at civilian women and writing about it in his little imperial uncle.
How is he not an accomplice of Konoha F4?
In some aspects, he even surpassed them.
In contrast, Kakashi... well, he's already a scarecrow, what more can be asked of him?
PS: A 'preemptive shot'... "Also, the scroll I left behind for practicing Rasengan is likely in the Hokage Building."
"It would be quite difficult for Naruto to acquire it through either of these two methods."
"Black-Framed Naruto found me," Nine-Tails Yin Half-Body gave him a look.
Minato Namikaze smiled and said, "Actually, there is an even better method."
"What method?" Nine-Tails Yin Half-Body also grew curious.
"I will teach him personally." Minato Namikaze showed a gentle smile.
Nine-Tails Yin Half-Body: "..."
"Both Kushina and I left behind Chakra imbued with consciousness."
"One reason was to see what our son looked like when he grew up."
"The other was to prevent Naruto from being misled by the other you and removing the seal tag on the sealing gate."
"In reality, tearing off the seal tag is only the first layer of defense."
"There is also a sealing lock on the sealing gate, and I gave the key to Jiraiya-sensei."
"I think... the other you in the black frame world should be able to figure that out."
Nine-Tails Yin Half-Body looked at Minato Namikaze speechlessly.
"You really did want to obtain this Fox's power."
"Your role is to prevent Naruto from being misled, while also considering the possibility of this Fox reconciling with Naruto."
"At that time, the Chakra you left behind wouldn't lose its purpose; you could even teach your son once."
"As for Kushina's..."
Nine-Tails Yin Half-Body didn't continue.
After seeing her son, it would be time to strike at him.
On the other side.
Seeing that Black-Framed Naruto had already guessed the method for practicing Rasengan, Jiraiya's eyes widened.
He could only say that he was truly the child of Minato and Kushina.
It seemed he had no need to appear.
No... he was still safeguarding the sealing key for Minato.
In the future, once Black-Framed Naruto found out, he would definitely come looking for him.
At that time, he certainly wouldn't hand it over easily.
During the testing phase, he would discover Black-Framed Naruto's intentions... Jiraiya painfully closed his eyes.
He knew that his counterpart in the black frame world would definitely intervene to stop him.
He might even kill Black-Framed Naruto himself for the sake of Konoha!
"No, this can't continue, I must find the child of prophecy as soon as possible!"
"As long as I find the child of prophecy, all problems will be solved easily!"
Inside the chat room.
Orochimaru: "Black-framed Naruto-kun is still so fascinating."
Orochimaru: "Rasengan, huh?"
Orochimaru: "As far as I know, the simplest and most effective way to practice Rasengan is by using balloons and rubber balls."
Everyone silently noted Orochimaru's statement.
Then they looked up seriously at Naruto on the black-framed large screen.
Black-Framed Naruto will definitely be able to deduce the complete training method.
After all, this is the Ninjutsu, Rasengan, developed by the Fourth Hokage!
You have to know, resources are basically fixed.
Where would civilian Ninja get the resources to exchange for promotion opportunities?
In most cases, carrying out missions is just enough to make a living.
Sometimes the mission reward isn't even enough to buy back the Ninja Tools damaged during the mission.
Ninjutsu?
What good is talent?
If you don't have a Ninjutsu scroll, how do you learn it?
Buying it from someone costs money, and asking a Ninja who masters the technique for guidance is another expense.
Iruka taught Naruto a few Ninjutsu that weren't even B-rank and was already bankrupt, owing a mountain of debt.
Coupled with their own talent... and having to execute missions while maintaining optimal condition... not everyone is like Naruto, who has such massive Chakra reserves for experimentation.
Just look at Kakashi, it's a fact that his strength has declined rather than increased over the years.
Even if he wanted to improve, he could use Raikiri a maximum of four times a day before his Chakra was depleted.
Using it more often could even cause him to faint.
How could he continue developing Raikiri then? Not to mention that he also needs to use the Sharingan during high-speed movement.
[Great Fox: ???]
[This brat... is heaven-defying!]
[I haven't even said anything, how do you know?]
[Impossible!]
[The Great Fox slightly narrowed its eyes.]
[Naruto continued to follow his train of thought.]
["Since it is a Ninjutsu that took three years to develop,"]
["there must be detailed records of it."]
["Logically speaking, Minato Namikaze should have left behind a complete training method... And as his wife, Mom couldn't possibly not know. If Mom knew..."]
[Naruto raised his eyes.]
[Their eyes met.]
["What are you looking at?"]
[The Great Fox looked completely displeased, and its tone was terrible.]
[Naruto's mouth curved slightly.]
[Since the Great Fox was showing such an expression,]
[how could Naruto not guess what the Great Fox was thinking?]
[He straightened his posture, then bowed deeply to the Great Fox.]
[He raised his head and said incredibly seriously, "Thank you, Great Fox."]
["I have never felt that everything I suffered in my childhood was caused by your existence."]
["On the contrary, having spent these years together..."]
[Naruto paused.]
[The Great Fox's two long ears stood straight up.]
[But it couldn't rush Naruto, and had to pretend to be impatient.]
["Great Fox, having you here is wonderful~"]
[Great Fox: "..."]
[You hateful brat!]
[You gave this Fox goosebumps all over the floor!]
[Aaaah!!!]
["Hmph!"]
[The Great Fox let out a cold snort.]
["Just practice this half-finished Ninjutsu left by your useless father."]
["That damned Fourth Hokage took three years just to figure it out."]
["As for the training method, it's just as you thought. After your useless father developed it, he already figured out how people could learn it."]
["First, you train using a water-filled balloon. Release Chakra into it and make the Chakra flow irregularly. Popping the balloon means success, but that's only the first step."]
["The second step is still related to a ball, but the durability of the ball needs to be increased a hundredfold."]
[A ball more durable than a balloon... a rubber ball?]
[Sure enough, the Great Fox continued: "The second step is to pop a rubber ball. Water is no longer needed; the main point is to feel the change in the Chakra's shape."]
["The third step no longer requires the aid of balloons or rubber balls. You only need to form the Chakra at high density and gather it in your hand."]
["All three steps require maintaining stable and continuous Chakra release."]
