Naruto naturally paid more attention to the Old Thing's son, Asuma Sarutobi.
He didn't pay much mind to Gekkō Hayate.
After comforting Yūgao Uzuki with a few words, he reassured her.
Besides that, Uchiha Izumi had already returned to normal.
Next, her body was expected to develop rapidly.
However, she still hadn't woken up.
According to Naruto's speculation, she would likely only wake up shortly after he became a Genin.
Uchiha Izumi waking up was tantamount to being reborn.
She no longer had to worry about the harm caused by prematurely awakening the Mangekyo Sharingan.
And nearly five years of dormancy would certainly raise her talent level again.
Of course, this was all a year away.
A year later, he would be twelve years old.
He would also reach the graduation age for the Ninja Academy.
The Ninja Academy was founded by the Second Hokage, Senju Tobirama.
He definitely took this specific point into consideration.
In other words, after the age of twelve was when the 'seal was truly lifted.'
Once he resumed training, he wouldn't have to worry about harming his body.
Naruto had endured this for a very long time.
Currently, there was less than a year left until the seal was lifted...
Senju Tobirama: "Hahaha, it seems this Old Thing's image in Black-Framed Naruto's mind isn't bad."
Uchiha Izuna: "It's whatever. I don't know how some people have the nerve to toot their own horn."
Uchiha Izuna: "Teaching a disciple like that, and that disciple teaching an apprentice like that—what an excellent lineage."
Senju Tobirama: "..."
Wait, Big Brother!
What's wrong with letting me show off a little?
"Great Fox, isn't it time to talk about the Ninjutsu Minato Namikaze created?"
Naruto looked at the lazy Scum Fox behind the sealing gate.
If it still refused to tell him.
Naruto wouldn't want to wait any longer.
He had already researched several feasible directions himself.
The Tailed Beast Ball made Naruto think of many things.
The most crucial point was allowing Chakra to appear stably outside the body.
To succeed, the first requirement was Chakra control.
Naruto already met this requirement, both in terms of Chakra control and spiritual power.
Now, Naruto had already started training in Chakra Nature Transformation.
If the Great Fox still didn't speak today, he would begin his own training.
Needless to say, to achieve a Ninjutsu like the Tailed Beast Ball, Chakra Shape Transformation was indispensable.
For example, referencing the Tailed Beast Ball, compressing a Fire Release Ninjutsu into a sphere, and then firing it out in one go, combining destructive power and speed.
Furthermore, Yūgao Uzuki hadn't been without results.
The flying Ninja, the Second Tsuchikage and the Third Tsuchikage, definitely used a type of Earth Release.
Moreover, that type of Earth Release had the effect of making objects lighter or heavier.
There was also one crucial piece of information.
Kekkei Tōta: Dust Release!
But there was too little related information.
Yūgao Uzuki didn't dare to publicly issue requests for help, or the Old Thing would inevitably become suspicious.
How could Naruto not see by now that the Old Thing was trying to use the same trick he once used on his mother and Minato Namikaze?
Clichéd, utterly unoriginal, and lacking ambition... but the effect, to be honest, was quite good.
He finally understood why Yūgao Uzuki had suddenly appeared before him.
Of course, judging by the current situation, the Old Thing was about to suffer a double loss.
Anko Mitarashi: "Yes, yes, yes, well done~!"
Ino Yamanaka: "Forget it, what's done is done... as long as we get to see the Old Monkey suffer a setback."
Tenten: "Exactly! Although I'm a bit uncomfortable too, making that disgusting Old Monkey suffer makes me feel much better."
Temari: "Hmph, instead of figuring out how to train by referencing your Black-Framed World self, you worry about these things. You'll be my subordinate loser for life."
Tenten: "Damn it, just you wait!"
"Oh."
The Great Fox responded lazily.
Naruto: "..."
This Scum Fox really holds a grudge.
"It's not that I won't teach you, but your self-control when it comes to training isn't very strong."
"If I teach you early, once you learn it, you definitely won't be able to resist continuing to expand on it."
There was one more thing the Great Fox naturally wouldn't mention.
Besides reading storybooks, it hadn't been idle!
Ever since it discovered Naruto's weakness, it had constantly been thinking of ways to train.
This scene stunned everyone.
What?!
Are you saying... Black-Framed Naruto is so competitive that even Kurama, a Tailed Beast, has to join in the competition?!
You must be joking?!
If even Tailed Beasts are this competitive, what are Ninja supposed to do?
Inside the Sealing Space, Kurama's eyes widened.
Huh?
I have to teach this brat the Rasengan?
This can't be real, right?
"Alright, lest some people accuse this fox of going back on its word."
"The Ninjutsu your father developed is the Rasengan."
The Rasengan?
Ra-se-ngan?
Is it a Tailed Beast Ball concentrated in the hand... a Chakra sphere?
Naruto was momentarily stunned.
In an instant, another technique appeared in his mind.
The Chidori of Minato Namikaze's disciple, Kakashi Hatake.
The Great Fox glanced at Naruto.
It was secretly astonished.
This kid... he couldn't possibly know what the Ninjutsu was just by hearing the name, could he?
He must. That look in his eyes was too familiar.
"Once you learn the Rasengan, you won't need to specifically train in Chakra Shape Transformation."
"To learn it, the first thing you need is the awareness of Chakra Shape Transformation."
"The Rasengan primarily involves condensing Chakra in the hand."
"To ensure that mass of Chakra doesn't dissipate, you need extremely strong control, which is Chakra Shape Transformation."
"The Chakra inside the Rasengan must continuously spin in different directions, and, like the Tailed Beast Ball, it needs compressive force to stabilize the technique into an externally stable sphere, while the interior remains chaotic and rapidly flowing Chakra."
Whoosh, whoosh, whoosh—
The instant the Great Fox's voice fell silent.
Naruto raised his hand.
Using spiritual power control, and following the Great Fox's instructions, he released a 'Rasengan' constructed from spiritual power.
A blue sphere of Chakra appeared in Naruto's hand.
The exterior was a stable sphere, just as Kurama had described.
The interior was chaotic and rapidly flowing Chakra.
"Hmm... that's about right."
"After all, it was created by referencing the Tailed Beast Ball."
The Great Fox curled its lip, not wanting to look at it at all.
This fox would never praise anyone!
"Compared to the Tailed Beast Ball, this technique is completely inferior."
"Of course, the difficulty of the Tailed Beast Ball isn't low, and first, you have to be able to... forget it, let's continue talking about this broken Rasengan."
"Training for it is also very simple. Step one: gather Chakra in your hand, ensuring it doesn't dissipate."
"Step two: turn the Chakra into a spherical shape."
"Step three: stabilize the sphere, and start gathering counter-rotating Chakra inside."
"The final step is roughly what you have now."
Naruto: "..."
Everyone: "..."
Is this teaching?
Didn't you just repeat what you said a moment ago?
You just broke it down into details.
A hint of schadenfreude flashed deep in the Great Fox's eyes.
Minato Namikaze spent three years developing and perfecting this Ninjutsu, and it was still only half-finished.
If even Minato Namikaze took three years, no matter how talented Naruto was, he wouldn't come bother it for quite some time.
When he can't stand it anymore and comes begging this fox for the secret, this fox will reluctantly explain it.
Haa—
Naruto took a deep breath, looked at the 'Rasengan' in his hand, and a flash of inspiration suddenly struck him.
"The exterior is unchanging... fixed, the interior is chaotic... a Ninjutsu like this must have considerable destructive power..."
"I've got it!"
Naruto's eyes lit up.
"The Rasengan... in every way, it looks like a water balloon that's been filled!"
