"This is it."
Shishou arrived at the Naka Shrine of the Uchiha clan.
After opening the hidden passage in the shrine, he slipped inside.
Half an hour later.
Having successfully obtained the Uchiha clan's secret scrolls, Shishou emerged from the shrine and closed the entrance.
Back home, Shishou put down the Shinigami mask, opened the obtained scrolls, and began quickly memorizing them.
Perhaps because his soul originated from another world, Shishou had excellent memory and comprehension abilities.
After gaining the Uchiha clan's bloodline and awakening the Sharingan, his memory and comprehension further improved, reaching the level of photographic memory.
He strongly suspected this was due to acquiring Yin Release chakra, which enhances spiritual power, significantly boosting comprehension and memory.
Of course, it could also be because his body had fully matured.
After two days of continuous memorization, Shishou finally committed all the Uchiha clan's secrets to memory and began training at home.
As for the academy, Shishou sent a clone made of insects to handle it.
A few days later.
Shishou finally mastered several basic genjutsu techniques of the Uchiha clan.
As for other skills like Fire Release and kenjutsu, Shishou made copies and then returned all the scrolls to Uchiha Mikoto.
During this meeting, Mikoto was noticeably warmer than before.
She subtly hinted that she was open to anything.
However, Shishou didn't make any moves on her, continuing to keep her in suspense.
This left Uchiha Mikoto quite frustrated, deciding to be even more forward next time.
...
Back at the academy.
Shishou casually glanced at Naruto Uzumaki, the future Hokage.
If he remembered correctly, Naruto not only had the Nine-Tails sealed within him at this time.
He also had the consciousness and chakra of the Fourth Hokage, Minato Namikaze, and Kushina Uzumaki.
And learning the Fourth Hokage's Flying Thunder God technique was his next goal.
Only after mastering the Flying Thunder God could he further his plans.
To prevent the ANBU around Naruto from noticing his intentions,
knowing Naruto often arrived late, Shishou began arriving just in time each day, trying to create a chance to inadvertently interact with Naruto.
A week later, due to staying up late, Naruto finally sat next to Shishou, unable to find another seat.
"Opportunity!"
At noon, seeing Naruto sleeping on the desk, Shishou was inwardly delighted.
He then casually reached out and touched the sleeping Naruto.
With the help of his three-tomoe Sharingan,
Shishou successfully entered Naruto's mindscape, where the Nine-Tails was sealed.
In a vast space, a gate separated him from the Nine-Tails.
"Nine-Tails, do you want me to release you?"
Looking at the sleeping Nine-Tails, Shishou smirked and kicked the bars of the seal.
"Hmm?"
"Where did this brat come from?"
Kurama opened one eye, staring at the young Shishou.
Shishou appeared very young, just about seven years old, the age he was while attending the academy.
"What's wrong? Don't you want to get out?"
Seeing Kurama's indifferent attitude, Shishou was puzzled.
Could it be that the Nine-Tails had been locked up for so long it had lost its mind?
Didn't it want to get out?
"Brat, you have the scent of the Uchiha. Get lost."
Kurama closed his eyes, resuming his slumber, clearly uninterested in talking to Shishou.
Tsk, so haughty?
Just because you hate the Uchiha, you give up on getting out?
"Tsk."
Though Shishou was just teasing Kurama, he found it boring when Kurama didn't take the bait.
Approaching the gate, Shishou reached for the seal tag on it.
Kurama, meanwhile, opened one eye slightly, watching Shishou's movements intently.
If Shishou removed the tag, Kurama was ready to break free.
Looks like it does want to get out.
Indeed, the haughty ones love to pretend otherwise.
Kurama's actions were clearly visible to Shishou's Sharingan, and he inwardly despised Kurama's tsundere nature.
Finally.
As Kurama watched tensely, a hand stopped Shishou's movement.
It was the Fourth Hokage, Minato Namikaze.
"Do you really intend to release the Nine-Tails?"
Looking at the blond, Hokage-robed Minato, Shishou grinned:
"Not really."
"If you hadn't shown up, I was about to leave."
This statement made Kurama gnash his teeth in anger.
Uchiha brats are truly infuriating!
"So, you came looking for me."
The Fourth Hokage, being very astute, quickly deduced that Shishou's target was himself, though he was curious how the boy knew of his existence.
"Fourth Hokage, I didn't expect you to be hiding here. Not even I knew."
"Tell me, where did you put my other half?"
Seeing the Fourth Hokage appear, Kurama's anger flared.
A violent malice surged in the sealed space, and Kurama's aura of destruction exploded.
Having lost half of its power, Kurama's strength was halved.
This made its hatred for the Fourth Hokage even stronger than for Uchiha Madara.
"Sorry, can you wait a moment?"
The Fourth Hokage looked at Shishou, then formed hand seals, transforming the bars of the seal into a wall, isolating Kurama outside.
After completing this, the Fourth Hokage turned to Shishou and asked:
"How did you know of my existence?"
