At this moment, Uchiha Ryōsuke saw the other party's full appearance: a massive Demon Fox with nine gigantic tails swaying behind it.
"Is this the Nine-Tails Demon Fox?"
"Can you please stop interfering with Naruto's training?"
The Nine-Tails Demon Fox grinned.
"So you came for that brat? As the vessel sealing me, restricting my freedom, do you think I'd let him have an easy time?"
"Don't be stupid."
Hearing the Demon Fox's words, Ryōsuke realized it was determined to disrupt Naruto's training.
He didn't know any sealing techniques to strengthen the seal and prevent the Demon Fox inside from interfering with Naruto.
Looking at the Demon Fox, he could only threaten it.
"Aren't you afraid I'll destroy you?"
The Nine-Tails was stunned for a moment upon hearing this Uchiha's words, then immediately spoke with a face full of mockery.
"I do indeed sense an extremely powerful aura from you, but aren't you being too arrogant? You actually dare to say you'll destroy me?"
"Besides, don't you humans seal me just to utilize the power within my body? Truly despicable humans."
Ryōsuke felt the other party made a lot of sense; he actually couldn't refute it.
In this space, he hadn't come in his true body, so naturally, he couldn't destroy the other party. His strongest technique, the Eight Inner Gates, had no place to be used here at all.
The other party must have realized this, hence the arrogance.
As for controlling the Nine-Tails' power, Ryōsuke certainly had no interest in it.
The Nine-Tails' power was just a bit stronger than the Eight-Tails. With his current physical attributes, opening the Eight Inner Gates would allow him to send the Eight-Tails flying with a single kick; he simply didn't need the other party's power.
Moreover, his own chakra volume was also growing through making love; it wasn't impossible for him to surpass the Tailed Beasts one day.
He spoke slowly.
"In that case, let's make a deal. If you don't interfere with Naruto's training, then in the future, when I have the chance, I can release you and return your freedom."
The Nine-Tails Demon Fox laughed.
"How rare. To actually meet someone who doesn't want my power. But even if you are willing to let me out in the future, the Jinchūriki will die as a result. You seem to care about this brat, don't you?"
"Even so, would you still release me?"
"Furthermore, aren't you afraid that if you release me, I'll seek revenge on your people in Konoha?"
Ryōsuke smiled.
"Afraid of your revenge? With your ability, you should be able to sense that there is another Tailed Beast's aura within the Uchiha grounds, right?"
"That was captured by me."
"I even captured the Eight-Tails Jinchūriki, I just let him run away, that's all."
"As for a way to undo your seal without harming the Jinchūriki, it's not like there isn't one."
"Since you can be sealed, naturally there is a way to undo it."
He wasn't worried about this matter in the slightest. At worst, he would just go deal with Orochimaru later. Although that guy was a character who was both good and evil, perhaps cooperation could be sought.
Even if cooperation couldn't be sought, he could rely on force to compel the other party to serve him.
That was a master of forbidden techniques; developing a way to undo the seal unharmed might be difficult, but it wasn't impossible.
The Demon Fox carefully sensed the Uchiha grounds. It hadn't expected there to actually be the aura of its own kind nearby. It seemed to be Two-Tails Matatabi.
They, the Tailed Beasts, were originally split from the same entity, so naturally, there was a connection.
And to think this guy actually let the Eight-Tails go; it didn't know if he was lying.
"How do I know if what you're saying is true or false?"
Ryōsuke said seriously, "I make this transaction with you in the name of the Uchiha Clan. I will show you some images shortly."
After speaking, his Mangekyō Sharingan activated directly.
The Nine-Tails was astonished. What powerful eye prowess. To think he can cast it on me even through the seal.
This terrifying brat is just like Uchiha Madara back then.
Its vision went black, and it fell into an illusion.
When it opened its eyes again, the scenery before it had changed.
A man carrying several swords, his body instantly flooded with the Eight-Tails' chakra, transformed into the Eight-Tails Gyūki. This was indeed the Eight-Tails Jinchūriki.
It hadn't expected the Eight-Tails, that guy, to actually be willing to let a human use its power. It truly threw away the face of the Tailed Beasts.
Directly in front of the Eight-Tails, a human figure charged toward the fully transformed Jinchūriki. He directly split the Eight-Tails open and pulled the Jinchūriki right out of the Eight-Tails.
Seeing such a scene, the Nine-Tails was shaken to its core.
In fact, the strength of a Jinchūriki's full Tailed Beast transformation wasn't much different from the original Tailed Beast's main body, yet such a powerful being was defeated directly.
When the other party said he could destroy it, he wasn't lying. Although it would be difficult, it was possible.
Even more strange was that the technique the other party used should be the Eight Inner Gates.
It hadn't expected that in this era, there was actually someone who could use such a technique and cultivate it to such a level.
The scene shifted, and it returned to the cage, looking at the person before it with astonishment.
Ryōsuke said with a smile, "How about it? Are you interested in making a transaction with me now?"
The Nine-Tails thought for a moment.
"That is naturally acceptable."
"However, if you deceive me in the future, then I won't let the Jinchūriki use even a speck of chakra."
"With my interference, the Jinchūriki won't be able to condense chakra and won't even be able to maintain his sanity."
Ryōsuke's expression changed. "I don't like these kinds of threats. Don't be so arrogant in the future, because I can find a way to get you out and then kill you. It would just take a bit of time."
After speaking, he exited the space.
Remaining in place, the Nine-Tails heard the other party's words and felt extremely dissatisfied in its heart. Truly an arrogant Uchiha Clan member. To actually want to kill me. This is even more excessive than Uchiha Madara and that Masked Man.
But inwardly, it was indeed a little worried.
The other party was right. It had originally thought he was just a very strong human.
It hadn't expected him to be that strong. Even the Eight-Tails wasn't his match, so it would also have a hard time coping.
Immediately, it withdrew all the chakra it had dispersed. This should complete the transaction with the Uchiha clansman who had just entered.
And its Jinchūriki should now be able to release chakra.
After Ryōsuke returned to reality, Fugaku immediately asked, "Did you go see that Nine-Tails?"
Ryōsuke responded, "Naturally. It was precisely his disturbance that caused Naruto to be unable to control his own energy."
"Naruto, try it again now."
Naruto prepared to give it a try.
The Demon Fox... that must be the monster sealed inside my body, right? Why was it sealed inside me and stripped of its freedom?
Never mind that.
He followed the method Uncle Fugaku mentioned, combining physical energy and spiritual energy, manipulating the combination.
A small wisp of chakra appeared in his meridians.
Fugaku couldn't help but say, "Truly a genius, even if it's just a small amount of chakra."
Naruto could naturally feel the small wisp of strange, unfamiliar energy in his body. That must be chakra. With chakra, he could release ninjutsu.
"Uncle Fugaku, hurry and teach me how to perform ninjutsu."
Fugaku laughed and said, "It's not that simple. Your bit of chakra isn't nearly enough to release ninjutsu. You still need to train more."
