Naruto: Uchiha Survivor Forced to Save the Shinobi World

After completing the summoning and bringing the other four Paths to the battlefield, the Animal Path slowly stood and asked the mysterious figure in a detached tone, "Are you the mastermind behind the 'Upper Ranks'?"

After scanning the Six Paths of Pain, the mysterious figure gave a wry smile and shook their head. "I still underestimated you."

The Human Path stepped forward. "Not talking? Then I'll take the answers myself!"

The mysterious figure drew the long sword hanging at their other hip, saying calmly, "At this point, what's there to say? There's only battle!"

A great clash was about to erupt!

Sensing the oppressive atmosphere, many Hidden Sand shinobi began to waver.

Even Chiyo was starting to regret her decision.

She had naively thought the Akatsuki's confrontation with the 'Upper Ranks' was the perfect opportunity for the five great shinobi villages to eliminate both threats at once.

But now, it was clear that both the Akatsuki and the 'Upper Ranks' were far more formidable than she had imagined. The Hidden Sand might suffer catastrophic losses because of her choice.

Zheng.

At that moment, a sharp twang of a biwa string rang out, and the surroundings abruptly shifted. The boundless grassland transformed into an unfamiliar city!

"We're in trouble now!"

Chiyo's face turned ashen, memories of being slaughtered by Kokushibo, 'Upper Rank Two,' in the 'Infinity Castle' flooding back.

The Hidden Sand shinobi, now scattered across different sections of the 'Infinity Castle,' descended into outright panic.

Itachi and Kisame, also trapped in the 'Infinity Castle,' found themselves in a different area.

Kisame surveyed their surroundings. "Itachi, is this a genjutsu?"

Itachi shook his head. "This isn't genjutsu. I suspect it's some kind of 'space-time ninjutsu.' We're trapped!"

Kisame was exasperated. "I've never even heard of this kind of 'space-time ninjutsu.' Have you?"

"Neither have I."

"Tch, this is bad! That last guy who showed up is probably the mastermind behind the 'Upper Ranks.' The leader—"

Kisame couldn't help but grumble, but when he mentioned the leader, he hesitated.

He genuinely couldn't tell which of the Six Paths of Pain was the true leader of the Akatsuki!

Itachi said nothing more and began moving through the 'Infinity Castle.'

On Uchiha Shinji's end, he too had been pulled into the 'Infinity Castle' and was momentarily stunned.

To maintain an overview of the situation, he had deliberately kept his distance from the battlefield. He hadn't expected the 'Infinity Castle' to cover such a vast range.

"It seems the chakra has enhanced Nakime's Blood Demon Art, making her 'Infinity Castle' even larger…"

With this realization, Shinji quietly rejoiced. For safety, he had sent out multiple shadow clones to seek aid. Otherwise, he'd have lost the ability to mobilize other villages' shinobi armies.

Tsunade's team, rushing toward the battlefield, encountered one of Shinji's shadow clones and learned the latest developments.

"Shinji, you've done well!"

After praising Shinji, Tsunade didn't hesitate, leading her team onward to the battlefield.

Almost simultaneously, in another direction, another of Shinji's shadow clones met the Third Hokage, leading an elite squad.

"Well done!"

After hearing Shinji's report, the Third gave him a meaningful look.

He hadn't expected this boy, still a student at the ninja academy, to not only survive the complex chaos of the Grass Country but also uncover such critical intelligence.

As a member of the reconnaissance team, Shinji had undeniably completed his mission perfectly.

The Third then instructed the accompanying communication shinobi to relay the latest intelligence and, like Tsunade, chose to hasten toward the battlefield.

The Hidden Mist army, closest to the battlefield, had already received the Hidden Sand's distress call and was heading that way. En route, they encountered both the Hidden Leaf's communication shinobi and Shinji's shadow clone, receiving updated intelligence. Realizing the opportunity, the Fourth Mizukage left the main force behind, leading an elite squad at full speed toward the battlefield.

Farther off, the Hidden Cloud and Hidden Stone armies had already rendezvoused.

With daylight driving the demons out of combat, they were advancing toward the Hidden Grass Village, planning to join the other three villages' forces there and wipe out the 'Upper Rank' monsters potentially hiding within.

Their first distress call didn't come from the Hidden Sand directly but was relayed through the Hidden Leaf's communication team.

Upon seeing terms like 'Eyes of the Sage,' 'Upper Rank One,' and 'Akatsuki leader,' the Fourth Raikage and Third Tsuchikage made the same decisive choice as the Third Hokage and Fourth Mizukage. They temporarily left their main forces behind, leading elite squads straight for the battlefield.

En route, they encountered one of Shinji's shadow clones, receiving the latest intelligence, and further accelerated, aiming to join the Third Hokage and Fourth Mizukage to combine the might of the five great shinobi villages and crush both the Akatsuki and the 'Upper Rank' mysterious forces in one fell swoop.

In an instant, the battlefield hosting the Six Paths of Pain and the mysterious figure became the focal point of all forces. Nearly every power scattered across the Grass Country was converging on that battlefield.

In the Infinity Castle, the Preta Path stepped forward, attempting to absorb the lightning from the spear piercing the Deva Path to free him.

But the moment they made contact, the Preta Path was electrocuted and flung backward.

Standing up, the Preta Path muttered, "This lightning's off. It's not pure chakra—I can't fully absorb it!"

The other four Paths tried various methods, but none could free the Deva Path from the spear.

"Perhaps only Almighty Push (Shinra Tensei) would work…"

The Preta Path shook their head.

Then, excluding the Deva Path, the five remaining Paths abandoned their rescue efforts and instead began surveying their surroundings.

The Human Path mused, "Space-time ninjutsu, huh? It hasn't exceeded my chakra control range, so we likely haven't been displaced far. Let's find that guy first."

Before the Human Path finished speaking, the Animal Path completed their hand seals and pressed their hands to the ground. "Summoning Technique!"

Poof.

With surges of massive white smoke, enormous creatures appeared within the 'Infinity Castle.'

Among them were a giant chameleon that quickly blended into the surrounding streets, a monstrous bird with black rods embedded in its body flying overhead, and a two-headed, drooling giant hellhound.

"Move out!"

The Animal Path waved their hand, and the summoned beasts rampaged through the 'Infinity Castle,' unleashing a series of thunderous roars.
