Uchiha Kei's expression was more solemn than ever before.
He could vaguely sense danger from behind that door.
Deadly danger!
With his current strength, to be honest, there are very few things that can give him a sense of danger, not even someone as strong as Ōtsutsuki Isshiki.
This means that behind this slowly opening door lies a terrifying being he has never seen before!
"What to do?"
Naruto's expression was also very serious.
His strength was inferior to Uchiha Kei's, and his feelings about it were more profound.
In his perception, behind that door lay an enemy comparable to Jing!
"Take Auntie away first."
Uchiha Kei didn't turn his head, staring straight at the door that was about to open.
Naruto nodded, picked up the still somewhat weak Kushina, and quickly left the courtyard.
Even he would have a negligible role against an enemy of that caliber, let alone his mother.
By sending our concerns to a safe place, we can prevent the enemy from hindering us.
After Naruto left, Namikaze Minato slowly walked to Uchiha Kei's side, two Kunai appearing in his hands at some point.
Who is this?
Uchiha Kei shook his head.
He had never seen anything like it in anime.
Even in the Boruto Naruto, the strongest boss was only Ōtsutsuki Isshiki.
But behind that door, there is clearly a power Ōtsutsuki Isshiki.
Kaguya stood beside Uchiha Kei, her expression very serious.
After careful consideration, Uchiha Kei began to speculate about the identity of the person behind the door.
The voice just now mentioned the Netherworld.
In the Naruto World, the Netherworld, or Netherworld, is a place that is frequently mentioned.
The six clones of Six Paths of Pain represent the Netherworld.
The Heavenly Realm, the Naraka Path, the Human Path, the Asura Path, the Preta Path, and the Beast Path.
These are merely channels for reincarnation in the Netherworld.
It's no secret that the soul of the dead goes somewhere.
It now seems highly likely that this place is the Netherworld.
Strictly speaking, the Impure World Reincarnation Ninjutsu only allows the soul to temporarily descend from the Netherworld to the human world; it will eventually return to the Netherworld.
Furthermore, those Impure World Reincarnation cannot be considered truly resurrected.
But he's different.
Those who passed through his hands, whether it was Hashirama, Tobirama, Uchiha Izuna, or Madara and Namikaze Minato, were truly resurrected.
Furthermore, the body he sculpted was far more powerful than that of ordinary people, and his lifespan would naturally be greatly increased.
This could be considered what that person meant by "manipulating the Netherworld."
Having figured this out, Uchiha Kei was no longer in a hurry.
The Netherworld is very powerful. Whether it's the Takamagahara of the Otsutsuki Clan or the Shinobi World, everyone who dies will return to the Netherworld.
In other words, the dimension of the Netherworld is higher than that of the Shinobi World.
It is virtually impossible for lower-dimensional beings to enter higher dimensions.
Is it easier for something of a higher dimension to enter a lower dimension?
Even if they manage to get in, their strength will probably be suppressed, right?
Of course, this is just Uchiha Kei's guess. What will actually happen depends on the actual situation after the guy behind the door comes out.
In that short time, the experts from Twilight Ninja Village also arrived.
Uchiha Izuna, Uchiha Madara, Senju Tobirama, White Bone Momotao, Hyuga Hiashi...
Seeing these powerful characters from anime gathered around him, Uchiha Kei felt a great sense of accomplishment.
Who else possesses his level of expertise and background?
"Boom!"
Before they could even greet them, the massive, dark gate in the sky suddenly burst open.
Thick black matter swirled and struggled within, attempting to break free from the giant gate.
"When!"
With a crisp sound, a huge and thick arm reached out from inside and gripped the edge of the giant door tightly.
Uchiha Kei narrowed his eyes, and his Ninja Blade instantly appeared in his hand.
It wasn't that he was being paranoid; it was just that the hand was exerting far too much pressure on him!
This has nothing to do with strength; it's entirely a matter of superior level!
He could vaguely sense that what flowed through this hand was not Chakra or some kind of energy.
It is the absolute power of rules!
A force of rules, much like time and space!
Of everyone, besides Uchiha Kei, Kaguya had the strongest reaction.
Kaguya's body trembled slightly, and her brows furrowed tightly.
From this hand, she could actually sense the aura that flowed through the legendary person from Takamagahara!
God!
The owner of this hand is a true god!
The giant hand, veins bulging, seemed to be struggling against something, barely managing to squeeze its way out of the door.
As more and more of the giant hand reached out, Uchiha Kei felt increasing pressure.
"Boom!"
Suddenly, a head emerged from beside the giant hand.
Deep blue lightning crackled across its head, and two ferocious fangs protruded from its enormous mouth!
"Despicable people, how dare you interfere in the affairs of the Netherworld!"
The enormous mouth opened and closed, and with each character it uttered, a clap of thunder echoed in the sky.
"Who are you?"
Uchiha Kei tightened his grip on his Ninja Blade.
He couldn't help but feel nervous; the existence of this head and its identity were now quite obvious.
A god who's a shoo-in!
A god from the Netherworld!
"I am the Eight Thunder Gods of the Netherworld - Big Thunder!"
Despite the tense atmosphere, Uchiha Kei couldn't help but smile when he heard his name.
Big Thunder?
Why not call it "Thunderclap"?
When Big Thunder noticed Uchiha Kei's smile, he became even more enraged.
What is this tiny mortal man laughing at?
Are they laughing at his name?
How outrageous! How dare they mock the gods!
"You despicable man, daring to mock the gods, die!"
The Big Thunder roar of fury echoed throughout the heavens and earth.
At the same time, a dazzling bolt of lightning suddenly burst forth from his wide-open mouth, surging towards Uchiha Kei.
Uchiha Kei frowned, and with a slight flick of his wrist, an invisible Blade Intent emanated from the blade.
"Bang!"
With a muffled thud, even the space itself seemed to distort slightly.
Finally, as the lightning dissipated, so did the Blade Intent.
Uchiha Kei breathed a sigh of relief.
From their exchange just now, he knew his guess was correct.
It is an extremely difficult task for the gods of the Netherworld to descend upon the Shinobi World.
Even a single attack will be significantly weakened.
He saw Big Thunder make his move clearly.
After the lightning burst through the giant gate, its power instantly diminished considerably, allowing him to use his casual Blade Intent to block it.
"Hmm? The Will of the Sword?"
Big Thunder was stunned for a moment.
In a tiny human realm, someone could actually comprehend the Will of the Sword?
And judging from the level of comprehension...
That's not low.
"Hmph, no wonder they dare to interfere in the affairs of my Netherworld, they're so confident they have nothing to fear."
Big Thunder sneered, a look of disdain in his eyes.
What about the Will of the Sword?
Without divinity, even the most profound will is no match for him.
I'm very sorry about this.
Uchiha Kei sheathed his sword, a hint of apology on his face.
"But..."
I won't change it.
Uchiha Kei tilted his head, looked up, and spoke with an air of self-righteousness.
At that moment, Kaguya felt that Uchiha Kei somewhat familiar.
Like...
Just like Naruto from before...
