Boom!!!
Like an asteroid hitting the Earth, when their fists clashed, the terrifying shockwave instantly turned everything in this different space to dust.
It was fortunate Naruto had thrown Amado out earlier, otherwise that guy would definitely have died here.
However, this violent collision was only a prelude… the real battle between the two was just about to begin.
Shhk!
Isshiki's arm transformed into a wooden claw-like appendage, directly slicing through Naruto's chest skin, piercing his muscles, and finally stopped by his bones.
But before he could cause further damage, Naruto landed two iron fists directly on Isshiki's head, smashing it into a shape like an apple core bitten from both sides.
Yet this seemingly fatal injury seemed to be nothing to the two of them now.
Although Isshiki's brain was scrambled, he could still control his other arm, transforming it into a spear and thrusting it toward Naruto's forehead.
Naruto, equally unaffected, had his Truth-Seeking Ball transform into a blade, once again unleashing swordsmanship that could cut through space.
He slashed off the attacking arm, then delivered a powerful roundhouse kick to Isshiki's waist and abdomen, sending him flying like a cannonball.
When Naruto prepared to attack again, he realized the slash he had made remained in the air, showing no signs of dissipating.
Through this mark, one could see chaotic and unstable spatial turbulence.
That was the scene Naruto had seen when performing Amenominaka in the Impel Down, the 'crack' between material spaces, a place where time didn't exist.
Even Naruto himself looked at his hand with some confusion after making this slash.
'Had I gotten stronger again?'
But he soon understood the reason.
It wasn't that he had gotten stronger, but rather that the structure of the different space they were in wasn't sturdy enough.
Unlike naturally existing material spaces, this forcibly created different space was inherently unstable.
Plus, its creator Isshiki wasn't particularly skilled in this type of spatial divine technique back then.
He wasn't like Kaguya, who had eaten the Chakra Fruit.
Being able to create this different space was already quite impressive.
The black spatial turbulence lingered, refusing to dissipate, completely different from how it appeared in the Ninja World or the One Piece World.
Spaces there could also be torn, but the cracks would quickly disappear again.
This was due to the space's self-repairing properties and stability.
With a sound of trees rapidly growing, Isshiki's severed arm quickly regenerated, and even his head plumped up again.
He seemed unwilling to let Naruto continue studying, and as soon as his body recovered, he opened his mouth wide and began gathering an attack.
A crimson energy ball rapidly expanded.
This was a Tailed Beast Bomb.
Or rather, compared to the purple-black Chakra Balls of Kurama and the others, what Isshiki was now performing was the true Tailed Beast Bomb.
"Roar!!!"
With a beastly roar from Isshiki, who had already started looking less human, this super Tailed Beast Bomb shot out instantly.
Seeing this, Naruto enthusiastically prepared to gather his strength for a 'beam struggle'.
But he soon remembered something else, his gaze shifting to the slash mark.
"Wait! No!"
He suddenly shouted, changing his hand gesture and canceling the action of performing the Conqueror's Bomb.
Wooo—
It was a terrifying sound like the wail of a deep-sea leviathan.
The huge crimson Tailed Beast Bomb exploded upon contact, the terrifying energy flow directly filling the entire different space, even the caster Isshiki couldn't escape.
The Chakra accumulated over a thousand years, combined with Isshiki's body, created such a spectacular explosion.
And this different space, true to form… began to collapse.
Starting from the spatial crack Naruto had first cut, black fissures began extending in all directions.
Isshiki's body continuously disintegrated under the frantic erosion of the energy flow, then regenerated using the combined recovery of the Ten-Tails and himself.
The pain from this process was unimaginable for mortals.
But Isshiki didn't care.
Now he only wanted to kill Naruto.
Unknowingly, the Ten-Tails' killing intent had again gained the upper hand… perhaps also related to the expanding 'plant-like' features on Isshiki's body as regeneration increased.
It seemed Isshiki dominated the merged body, but who actually had the upper hand and who would laugh last was still unknown.
Isshiki had still underestimated this Ten-Tails he had imprisoned for a thousand years.
'Good, just like this!'
'Uzumaki Naruto is doomed!'
Though his throat couldn't produce sound, Isshiki still roared silently.
The energy flow near him was rapidly shrunk, but even shrunk, more energy continued to fill in, maintaining the erosion of his body.
Isshiki laughed wildly, as if venting all the frustration of a thousand years.
"Oh? Is it almost over?"
The frequency of the energy assault began to decrease, and even his vocal cords could sustain one sentence before disintegrating.
But… things were a bit different from what Isshiki imagined.
The energy that filled his vision suddenly began to flow toward a certain position, like water flowing to lower ground.
Ahead, there was a force field invisible to the naked eye 'capturing' this energy.
"This… impossible!?"
When the energy flow finally thinned enough for Isshiki to clearly see the scene before him, he instinctively exclaimed.
Before Isshiki was a pitch-black humanoid form, yet also shimmering with faint light like a starry sky.
Onogoro.
The ability born from the combination of Naruto's Kokugan and the Baku Baku no Mi, symbolizing the most dangerous celestial body in the universe… a black hole.
In this state, no matter what attack, or rather, no matter what energy… nothing could escape his 'capture range'.
Naruto, like a black hole, absorbed all energy, the residual traces of energy crushed by the gravitational field forming streamers like a starry sky.
"…"
Naruto opened his mouth, but realized no sound came out, remembering that in this state, even sound couldn't escape.
Realizing this, with a thought, his body rapidly changed from black to white.
"Inversion."
This was the second half of this ability's effect.
Matter cannot disappear from existence… it only transfers from one place to another.
Even planets swallowed by black holes in the universe are the same, only transformed into another form, ejected by a connected 'White Hole' elsewhere, becoming the foundation for a new planet.
"Damn, almost got screwed by you."
This was the first thing Naruto said.
He was somewhat scared.
Not because he feared being killed by this explosion, as with Amenotorifune, he could instantly leave.
Naruto was worried about whether the destruction of this space would affect the Ninja World.
With his Jogan, Naruto could see scenes previously invisible.
The chaotic spatial turbulence was analyzed layer by layer under the Jogan, revealing the connection between this different space and the 'main space' of the Ninja World.
The energy surging enough to destroy this different space was temporarily bound in Naruto's palm by the effect of Onogoro.
But even so, Naruto could still feel the highly unstable energy about to erupt.
He was about to explode!
He had to find a safe place to release it.
And it couldn't be different spaces like Amenominaka or Mount Myoboku, as their fragile spatial structures couldn't withstand such a blast.
He had to return to the Ninja World.
Just as a small soap bubble bursting next to a large one might also destabilize the large bubble.
But an explosion of the same scale, if placed inside the large bubble, probably wouldn't cause much fluctuation.
Because the large bubble's stability and structure were stronger.
With this thought, Naruto instantly appeared beside Isshiki, pressing his palm on the other's forehead.
"Let's go, change of venue!"
Isshiki instinctively wanted to resist, but Naruto in the 'White Hole' state was completely unmovable by him now.
He could only be grabbed by Naruto and forcibly transferred back to the Ninja World using Amenotorifune.
…
Back in the Ninja World, Naruto didn't release the energy immediately.
An explosion of this magnitude could completely destroy the continental shelf, wiping out the Five Great Nations. He needed to find a place sufficiently open and far enough from the Ninja World.
And this place had to be within Naruto's reach.
It was around evening now, the sun gradually setting, the moon hanging high in the sky.
Looking around for a release position, Naruto was immediately attracted by the moon.
Right!
The moon!
That distance he could see with his naked eye, yet it wouldn't affect the Ninja World's planet.
With a thought, an Amenotorifune mark began transferring toward the moon through Naruto's 'sight projection'.
It turned out that Amenotorifune wasn't truly 'zero-time movement' either.
After all, even light had a speed limit.
But fortunately, compared to light speed, the distance between the moon and the Ninja World wasn't too far.
After a 'delay' of about two or three seconds, Naruto felt the Amenotorifune mark successfully planted.
Alright, let's go!
The next moment, the small glowing figure, along with the plant-like figure, teleported again, disappearing from the Ninja World's continent.
