"Hey! Kid! Kid!
Quit playing dumb. It's time we talked."
Feng absorbed the usage methods and experience of the Flying Thunder God Technique — Minato Namikaze Version in his mind, while the Nine-Tails, which had been waiting impatiently inside him, kept roaring.
And as Feng's entire consciousness immersed itself in the newly acquired Flying Thunder God Technique, his distracted state allowed the impatient Nine-Tails to successfully drag him into the mental space.
Moreover, the seal imprisoning the Nine-Tails inside him was the Four Symbols Seal, unlike Naruto's Eight Trigrams Seal.
Thus, the seal on the Nine-Tails within Feng's mental space was naturally not as sturdy as Naruto's.
So the moment he entered the mental space, with a thunk, Feng took a heavy flick to the forehead from one of the Nine-Tails' fingers.
That was only because the Nine-Tails had taken into account that Feng knew both his name and Hagoromo's. Otherwise, that claw just now would have left him dead or crippled.
"Kurama, can't you wait just a little longer...?"
Feng rubbed his aching forehead and said helplessly.
"Cut the crap. Tell me where you learned that my name is Kurama, and where you learned the old man's name."
The Nine-Tails roared impatiently. As it spoke, one of its claws completely covered Feng.
It looked as though it would kill Feng if his answer failed to satisfy it.
"Heh, here. See for yourself."
Facing the Nine-Tails' threat, Feng merely chuckled and held out a clenched fist.
Knowing that the Nine-Tails could share memories they wished to share through a fist bump, he had long prepared for this.
After all, if he sealed the Nine-Tails inside himself but failed to build a good relationship with it, the result would only be a one-use weapon of war.
But that was not what Feng wanted. He still counted on the Nine-Tails' nearly limitless chakra to serve as his power bank, allowing him to use Flying Thunder God and Susanoo without restraint to dominate the Ninja World.
"You know about this too?! Looks like you know quite a lot, kid.
Hahaha, then let me see what you want to show me."
Seeing Feng's outstretched fist, the Nine-Tails froze for a moment before laughing. It extended its own clenched claw and bumped fists with Feng.
"Feel pain! Think about pain! ..."
The first memory received by the Nine-Tails was Nagato's classic scene of assaulting Konoha.
The Rinnegan and the capture of the Nine-Tails—those two pieces of information immediately gave the Nine-Tails a huge fright.
"The Fourth Shinobi World War—I hereby declare it begun."
"Ten-Tails Jinchūriki! Make your entrance!"
"Infinite Tsukuyomi!"
"A dream world without ominous chakra has begun."
"I have nothing to say to people like you, who don't understand the meaning of chakra and toy with it as you please."
Next came the Masked Man, Obito, starting the Fourth Shinobi World War; gathering all nine Tailed Beasts and becoming the Ten-Tails Jinchūriki; Madara Uchiha being revived, becoming the new Ten-Tails Jinchūriki, and launching the Infinite Tsukuyomi; followed by Kaguya Otsutsuki's appearance.
Feng shared everything about the Fourth Shinobi World War with the Nine-Tails, except for the final outcome.
"So the old man had a younger brother? And that guy caused everything in the future!?"
After a long while, the Nine-Tails finally came back to its senses after receiving memories of the future from Feng.
"Yes, you saw it too.
In the future, they will gather you and the other eight Tailed Beasts to revive the Ten-Tails and trigger the Infinite Tsukuyomi.
My goal is simple: to live well and prevent them from launching the Infinite Tsukuyomi.
If I get the chance, or if it's possible, I'll also find a way to kill Black Zetsu and Obito.
But that is somewhat difficult with my own strength alone, so I thought of you.
Kurama, the Sage of Six Paths' most beloved child, the strongest among the nine Tailed Beasts.
Only with your help will I have the confidence to kill Black Zetsu and Obito."
Feng spoke almost without thinking.
He had drafted those words in his heart from the moment he decided to become a Jinchūriki.
Only, for the flattering words aimed at the Nine-Tails, he had also considered what to say to the Three-Tails and Seven-Tails as alternatives.
"The future you shared feels real, but I still cannot fully believe it.
So prove to me where you got this future from.
As long as you can prove it, I don't mind helping you a little."
The Nine-Tails pondered for a moment before speaking again.
It actually already mostly believed the future Feng had shared, since much of what it involved was known only to the Sage of Six Paths.
But after being sealed away for decades and slandered by humans as a natural disaster for a thousand years, it could not completely trust a human.
Especially someone it had only met for the first time today, who had sealed it inside his body.
Hearing that, Feng did not explain immediately. Instead, he activated his One-Tomoe Sharingan and displayed the Susanoo copied from Uchiha Fugaku.
"You bastard! You're from the Uchiha Clan too!"
The instant the Nine-Tails saw Feng's Sharingan, it flew into a rage and nearly attacked.
"Yes, but I am not with Madara and Obito.
Otherwise, I would not have shown you the future."
Feng explained naturally with a smile.
"Hmph, I know. Otherwise, I would have attacked already.
Let's continue what we were just discussing. Prove where you learned of the future."
The Nine-Tails arrogantly drew back both claws, raised its eyes, and spoke disdainfully.
"As you can see, I am from the Uchiha Clan, and I have also awakened the Mangekyō Sharingan."
As he spoke, Feng used Susanoo's hand to pat the Nine-Tails. But he immediately dismissed Susanoo afterward, because... he had run out of chakra...
However, none of that mattered. Neither man nor fox cared, and Feng continued speaking:
"Kurama, I wonder if you know that every pair of Mangekyō Sharingan awakens with two special ocular techniques."
"I'm not an Uchiha. How could I possibly know that?"
The Nine-Tails rolled its eyes at Feng and replied casually.
"Now you know, heh.
And one of the ocular techniques awakened by my Mangekyō Sharingan was Future Observation."
"No, your eyes aren't Mangekyō. I've seen Madara's Mangekyō, and it didn't look like yours."
"Mm, you're right. My eyes indeed aren't Mangekyō now.
And that is because of the Mangekyō's side effects and my other ocular technique."
The Nine-Tails raised a brow, signaling Feng to continue.
"Back when I had just awakened my ocular techniques, I immediately observed the future.
But I discovered that my Uchiha Clan would soon be exterminated by Konoha, and that I would die in the clan's extermination as well.
Then, for myself and for my clan, I constantly used my ocular technique to observe the future.
I searched for a way to let myself survive, and to let the clan survive.
However, the Mangekyō had extremely severe side effects. Every use caused my eyesight to decline.
Normally, my eyes would have gone blind after observing the future only a few times.
But my other ocular technique, Body State Reversal,
just happened to compensate for that side effect.
Finally, after who knew how many observations, I found a way.
But an accident also happened. Through repeatedly reversing my body's state, I reversed my Mangekyō away and directly returned it to its current One-Tomoe Sharingan state.
Of course, the ocular techniques disappeared along with it.
If I could not still activate Susanoo, which only a Mangekyō could use, I would have thought I had fallen under a genjutsu."
Feng continued explaining. In truth, he had long fabricated these words, and now he spoke them without blushing or skipping a beat, as though they were real.
That was because he was taking advantage of the fact that the Nine-Tails possessed only evil-sensing abilities, not lie-detecting abilities.
The Nine-Tails fell into thought.
It had just said it did not understand the Mangekyō, but as the Sage of Six Paths' most beloved Tailed Beast, combined with having been controlled by the Mangekyō multiple times and its thousand years of experience, it actually knew something about it.
So it began comparing its own knowledge against Feng's words to distinguish truth from lies.
After a long time, the Nine-Tails finally spoke:
"For now, the future you shared with me should be real.
So I've decided to help you.
But after Black Zetsu and Obito are killed, and after Madara Uchiha and the old man's mother are prevented from being revived,
you! Uchiha Feng, will also be my enemy."
The Nine-Tails' tone remained full of disdain and arrogance.
Yet Feng could also hear a trace of fear and dread within it.
But he did not expose the Nine-Tails. After all, he still needed it to be his power bank in the future.
Besides, fearing death was only human nature.
The Tailed Beasts had never died or been destroyed for a thousand years, so they had originally feared nothing.
But in the future Feng had shared, if they were fed to the Ten-Tails, the Tailed Beasts could die too.
It was only natural for the Nine-Tails to be afraid after realizing for the first time that it could truly die.
"Good. Then, Kurama, I'll be relying on you for the time ahead."
Feng smiled and reached out to grasp the tip of the Nine-Tails' claw. Man and beast reached a preliminary understanding.
