Konoha.
"Keigo, do you understand it?" Satoru sat on the sofa, looking at his three-year-old son, who was constantly flipping through a book, and asked curiously.
That book was advanced mathematics.
Keigo heard this, and turned to the next page: "It's a bit difficult. Compared to intermediate mathematics, the learning difficulty of advanced mathematics has increased by more than just one point."
"If you don't understand, then don't look. Come here and let your dad teach you. Your older brother and sister were all taught by me back then."
Satoru raised his head and said proudly.
He was an Omnipotence academic.
Over the years, using Shadow Clone, he had learned an unknown amount of knowledge.
Not just in the area of Ninjutsu.
He could not only call himself a Ninjutsu professor but also a professor of other subjects.
"No need, I feel that you, Dad, wasted the talents of my older brother and sister.
This level of difficulty only requires a little more time than intermediate mathematics."
Keigo said unceremoniously.
He didn't look like a child at all.
His eyes shone with the light of wisdom, dazzlingly bright.
"...You really are disheartening your dad..."
Satoru was speechless.
He had wanted to take on the responsibility of being a father again.
He hadn't expected that Keigo was nothing like Tenyu and Maki.
He was too smart, leaving his dad with no sense of involvement.
And he was very well-behaved; whatever he was asked to do, he did very well.
His talent was much higher than Tenyu and Maki's back then.
Although this was a research-oriented mindset, it might not be like Shikamaru's intelligence.
He hadn't grown up yet, so it was hard to say.
However, Satoru was already sure that his youngest son might become his good helper in the future.
"You just do your own thing; you don't need to worry about me. If I don't understand, I'll come to you."
Keigo spoke with a decisive and resolute air.
He just annoyed his dad a bit.
"Hmm, so annoying!"
Satoru was helpless.
However, at this time, Naruto should be returning from outside soon, right?
..."Perverted Sage, let's go! It's been a long time since I've been back to Konoha.
When I get back, I'm definitely going to have a big meal."
Naruto's voice reached Jiraiya's ears.
At this moment, Naruto was wearing the new clothes Jiraiya had bought him.
He looked like a handsome young man.
He also carried a backpack on his back.
"I know, really, there should be another group of girls coming here to play this afternoon!"
Jiraiya looked at the waterfall and stream in front of him with reluctance.
These past few days here had brought him unforgettable times; it was truly wonderful!
Then his eyes changed, and his expression became serious.
During the days he had brought Naruto out to train, he hadn't forgotten the existence of the Akatsuki Organization.
From the intelligence he had gathered,
he feared... the Akatsuki Organization's large-scale operations were about to begin.
Jiraiya thought of the Great Toad Sage's prophecy.
Then he shook off the distracting thoughts and walked towards Naruto with a smile.
"Naruto, use Multiple Shadow Clone to perform the Harem Jutsu one more time. I'll check your results."
"Perverted Sage, we're going back, stop playing."
"No, no... Naruto..."
As they laughed, their figures stretched longer and longer.
Jiraiya looked at Naruto's back, a smile playing on his lips.
"He's so similar. Will Naruto be that savior? Will there be a mistake?
After two and a half years of foundational training, even if something happens to me,
Naruto will be able to learn Sage Mode in a short time, greatly enhancing his strength,
and thus face powerful enemies.
Oh, right, it's a pity he didn't learn Satoru's invisibility Genjutsu!"
As he thought, Jiraiya's mind wandered... In the dark underground space.
Chidori chirped, a spear-like bolt of lightning, the Chidori, plunged from Uchiha Sasuke's hand into Orochimaru's chest.
Orochimaru spat himself out from his mouth.
He looked at Sasuke with great satisfaction.
"Very good, your body already possesses the foundation to surpass Itachi.
I will help you get your revenge then."
"I'm going back to rest. Prepare my secret medicine for tomorrow. I don't want any mistakes."
Sasuke's face was no longer childish, but that of a handsome young man.
He showed no politeness in his words to Orochimaru.
It was as if he were the master here.
Then Sasuke walked through the passage behind him, disappearing from Orochimaru's sight.
Whoosh!
"Lord Orochimaru, how can he speak to you in such a tone?
He clearly doesn't respect you at all."
Kabuto appeared beside Orochimaru, his voice filled with dissatisfaction.
"Hehe, it's fine. Don't we have to satisfy a death row inmate's appetite before his execution?"
Orochimaru looked in Sasuke's direction, licking his lips.
"How is your research? Have you made any progress?"
"Yes, regarding the nerves left by Satoru, I have found a way to guard against them.
But I hope not to encounter him, after all, this is only one of his abilities."
Kabuto pushed up his glasses and said confidently.
After more than a year of research, he had finally, under Lord Orochimaru's guidance, successfully deciphered the nerves left by Satoru.
And found methods to counter these nerves.
They simulated various possible applications of these nerves and developed various countermeasures.
"That's good. For such an ambitious fellow,
it's better to be prepared."
Orochimaru looked at Kabuto with great satisfaction.
The only thing he was dissatisfied with was that Kabuto's goal was too vague.
He couldn't unleash Kabuto's full potential.
His eyes looked in the direction Sasuke had left, once again revealing a look of longing.
It was almost time... Swish, swish!
In the underground space, numerous figures transformed into colorful lights, appearing from the ten fingers.
"Everyone, Akatsuki's time has come. Our plan is about to be completed. For our great ideal,
let's strive! Next is the task of assigning the Tailed Beasts.
Deidara, Sasori, the Ichibi of Hidden Sand Village, I'll leave it to you two. Can you do it?"
Pain spoke.
"Hidden Sand Village, huh? It's been a long time since I've been there. I'll take it." Sasori said.
Deidara: "No problem."
"Hidan, Kakuzu, your target is the Two-Tails..."
"Itachi, Kisame, your target is the Four-Tails..."
Soon, Pain finished assigning the tasks of capturing the Tailed Beasts.
"Then, if there's nothing else, let's depart. Our Akatsuki Organization will ultimately reshape the world..."
"Leader-sama, I have something to say. Be sure to avoid that fellow named Satoru.
From my intelligence, that guy is very deeply hidden.
He's probably not as simple as just a Genjutsu-type Ninja."
Zetsu suddenly spoke.
"Why do you say that?"
"Although we have prepared methods to break Genjutsu, from the intelligence I gathered in Konoha,
the opponent is not just Genjutsu; he has probably also learned some of Konoha's forbidden Ninjutsu.
He's probably a big problem."
Zetsu introduced to those present.
He had heard interesting news from the Shimura Clan's territory.
Satoru, during his time as Acting Hokage, strongly requested to view Konoha's sealing scroll, which was probably not as simple as mere curiosity.
Zetsu hated such variables the most.
"Konoha's Nine-Tailed, I'll take care of capturing it when the time comes." Pain heard this and took on the mission to capture the Nine-Tailed.
Satoru's strength was more mysterious than that of the Kage of the Five Great Ninja Villages.
