The Eight Trigrams Sealing Style.
It might look like just two Four Symbols Seals overlaid on each other, but the complexity, precision, and most importantly, the sealing strength presented were far from a simple 1+1=2 result.
The most important part of this seal was finding the corresponding control points.
Then inlaying them one by one.
To achieve a perfect echoing restriction between the outer and inner circles.
Previously, Menma's understanding of the Eight Trigrams Sealing Style was based only on his knowledge of the Four Symbols Seal. But now, having obtained the core content of the jutsu series from Minato, Menma clearly realized his previous thinking was too simplistic. It wasn't that using the Four Symbols Seal to reverse-crack it was completely useless, but rather that the difficulty encountered would be infinitely high.
It was hard for an average person to achieve, and it could easily cause conflicts between sealing jutsu.
Especially when involving Tailed Beasts.
A single slip-up, and the Tailed Beast chakra could easily go out of control.
Of course, Menma didn't need to worry about this problem, since the Nine-Tails could now be considered one of Menma's capable assistants.
But even if it was just the problem of sealing jutsu conflict, that wasn't something Menma wanted to see. Ultimately, having fewer troubles was best.
"Four Symbols Inscription!"
Comparing it with the core content of the Eight Trigrams Sealing Style he had just obtained in his mind...
And contrasting it with the circle of Four Symbols Seal marks from before...
Menma inscribed rune marks again on the outer circle.
When all preparations were complete...
Rip!
Menma didn't hesitate to tear off that sealing paper directly.
Revealing a complex sealing pattern.
The moment he saw it...
Menma's hands immediately formed seals.
A wave of chakra surged out accordingly.
The next second.
"Reverse Eight Trigrams Release!"
"Break!"
Accompanied by a deep shout...
Menma's right palm pressed rapidly onto the spiral sealing pattern.
Buzz!
The metal bars vibrated accordingly.
Click!
A crisp sound of a lock disengaging rang out.
From a direct angle...
One could see the complex sealing lock slowly rotating counter-clockwise, opening circle by circle.
Inside...
The Nine-Tails could clearly sense the suppression on his body slowly dissipating.
He couldn't help but stand up straight.
A special gleam appeared in his massive crimson fox eyes.
"Open!"
As the sealing lock turned to the final circle...
The next moment.
Menma clearly detected the critical point.
Chakra was further refined.
With a heavy shout...
Rumble!!
Crash!
An obvious crack appeared in the middle of the sealing lock instantly. Just a few seconds later...
Bang!
It shattered directly.
Fragments flew in all directions.
Turning into nothingness in mid-air.
And at the moment the sealing lock was completely broken, the massive metal bars imprisoning the Nine-Tails also trembled violently.
This clearly perceivable surging sensation.
A feeling of complete freedom, as if there were no restraints.
The Nine-Tails looked up and roared.
"Roar!"
A monstrous wave was whipped up.
This chilling chakra fluctuation permeated the air.
Clatter!
The metal bars were blown away instantly. With the seal completely broken, the Nine-Tails was now thoroughly unrestricted.
This aura soared into the sky.
Wind surged.
Blowing Menma's clothes wildly.
Boom!
As the Nine-Tails stepped forward, his slowly lowered eyelids stared straight at Menma in close range. The dangerous aura flowing from his body was so cold, so fierce!
One step.
Only one step away from true freedom.
Just defeat the boy in front of him, then seize control of his body, and he could truly gain freedom!
This was a massive attraction for the Nine-Tails.
Even for a Tailed Beast that had lived for a thousand years, decades of imprisonment were enough to make them feel irritable and angry.
This feeling of being completely restricted by humans...
They truly found it hard to accept.
And now, the opportunity for freedom was right in front of him.
To say the Nine-Tails wasn't tempted at all would be absolutely false. That restless aura was so intense, that longing look so obvious.
A naked posture of being ready to start a war at any time.
But Menma still met his gaze with a calm expression.
Slightly profound eyes.
Still a composed posture.
Looking at Menma like this, just a few seconds later...
The Nine-Tails snorted lightly.
"Hmph, you really aren't afraid that this old man will attack directly!"
"Heh, Kurama, I've already said it. We are a community of shared destiny. If I die, you might indeed gain true freedom for a period. But unless there is truly a place where you can hide completely, you will eventually have to face those guys. At that time, you'll have to bear the risk yourself!"
Menma chuckled lightly, not caring about the Nine-Tails' attitude at all, speaking in a flat tone.
He wasn't Naruto; he would never engage in those fake things.
Whether facing Orochimaru, Sasuke, or the Nine-Tails, Menma's approach was always to lay out the realistic side.
The approach of mutual understanding seemed the most laughable to Menma.
Because no matter what creature, it is forever impossible to achieve true empathy.
Even if they could, there would ultimately be huge gaps between people, and between different creatures.
It wasn't that Menma didn't believe in sincere emotions or mutual understanding—after all, didn't he have Karin? But that was ultimately the minority.
What this world needed wasn't this!
Menma had always seen this point very clearly and thoroughly.
"Hmph, you win, kid. Then, can you tell this old man everything? I believe you know absolutely more than that. Including that bastard Madara Uchiha—tell me, is that guy still alive!?"
The Nine-Tails snorted again, then stared fixedly at Menma, his words filled with killing intent.
For the Nine-Tails...
The most hateful human in the past thousand years was undoubtedly Madara Uchiha.
Not only could this guy suppress him easily, but he also blatantly treated him like a pet to be driven at will.
This was a great humiliation for the Nine-Tails!
This was the existence the Nine-Tails wanted to wash away his shame against the most.
"Alive? Definitely not alive. But this guy is the mastermind behind all of this. He should be waiting for the opportunity for resurrection to arrive right now!"
