Naruto Rebirth : Rewriting Fate of the Ninja World

Konan asked, "Hell Valley? I've never heard of that place before."

Naruto smiled. "It was a top-secret location of Kumogakure. I only learned about it after becoming Hokage."

"The climate there is extremely hot one moment, freezing cold the next. It's a brutal environment, dangerous even for veteran shinobi. But because of that, it's perfect for strengthening the body. Only Raikages and their chosen successors are allowed to train there. If they can survive it, a single day of training can be worth a hundred days elsewhere."

Konan was amazed. "A place like that must have a unique origin. Was it naturally formed? I don't know any ninja powerful enough to create such a place."

Naruto shook his head. "It's not natural. It was created by a descendant of the original Ninja Clan during the era of the Sage of Six Paths."

Konan's eyes widened. "From the time of the Sage of Six Paths? One of his clan's successors?"

Naruto nodded. "The Land of Lightning, where Kumogakure is located, has deep roots with the Six Paths Ninja Sect. Some descendants of the Sage even settled there and passed on powerful techniques and relics."

"Kumogakure inherited several of the Sage's tools. Even the infamous Ginkaku and Kinkaku brothers had some Uzumaki blood, along with their Night Moon Clan heritage. I discovered that later while tracing the Uzumaki family tree."

"And it's not just Hell Valley. There's also the True Falls on Turtle Island, a sacred place for inner training. That's where I went to learn to control Kurama's power. Kumogakure controls that too."

Konan frowned, concerned. "So… does that mean we'll have to face Kumogakure again? If so, I'll go with you."

Naruto smiled and said, "No need. Hell Valley isn't inside Kumogakure it's in the Land of Lightning. I know exactly where it is. I was invited there once in my past life as Hokage."

"The environment is so harsh that even I could only endure it by using Kurama's Chakra Mode. It's really not a place suited for you, Konan-san. So this time, let me handle it alone."

"Don't worry, though. To be safe, I'll leave a clone behind in Amegakure. With my clone there, it'll be just like I never left."

Hearing that, Konan finally relaxed. "Alright then… just be careful."

….

Land of Lightning

After teleporting with the Flying Thunder God, Naruto traveled through the night. By dawn, he reached the dense jungle outside Hell Valley.

Since Hell Valley was a stronghold of Kumogakure, it was likely well-guarded.

Naruto didn't rush in. Instead, he activated Sage Mode to scout out the positions of the guards.

Naturally, some of Kumogakure's guards were sensory-type ninjas. But Naruto had positioned himself just outside their detection range.

"Phew…"

Naruto stood up. Purple lightning crackled across his body. He took a deep breath—then shot forward in a flash of purple light, heading straight for his destination!

Swish!

A purple streak zipped past the Kumogakure outpost.

"Did something just fly by?"

"Where is the intruder? Was it an illusion?"

"I scanned the area—there's no one!"

"I mean, who else besides Raikage-sama could move like that? But our Raikage-sama is still training inside Hell Valley!"

"Keep patrolling!"

...

After passing through a thick mist, the scenery suddenly changed—Naruto had arrived at Hell Valley.

It was a deep valley surrounded by mountains, with only a single narrow path leading inside. The sky above was dark, covered in volcanic ash, casting a gloomy and chaotic atmosphere over everything. The heat was so intense that the air shimmered with haze.

Naruto looked around and smiled to himself. 

"Just like when I came here last year... but that time, I was invited. This time, I came uninvited." He stepped onto the only path and moved forward.

The deeper he went, the harsher the environment became.

After about thirty minutes of walking, a massive training platform built into the side of a cliff came into view.

"No need to rush. I should let my body adjust first." 

Swish!

Naruto leapt onto the platform and slightly reduced the lightning covering his body.

The effect was immediate beads of sweat poured from his body as the intense heat hit him full force. He closed his eyes and focused, forcing himself to endure the extreme conditions.

An hour later, without warning, the climate shifted. 

The scorching heat suddenly gave way to a biting cold. The extreme and rapid temperature changes were enough to kill an ordinary ninja.

Naruto took a deep breath, glanced around, and created multiple Shadow Clones. Not wanting to risk overexerting himself, he summoned only a hundred this time.

Training like this continued for an entire day and night.

Finally, he released the clones, one by one.

"Huh." Naruto took a deep breath and slowly removed the layer of lightning chakra covering his body.

Without the protection of his Purple Lightning Chakra, he found he could still endure the harsh environment. He smiled with satisfaction. "Alright… time to go deeper!"

He left a Flying Thunder God mark on the training platform, then jumped down and continued forward.

When the conditions became too harsh again, he reactivated his Lightning Chakra to protect himself and pressed on until he reached the second training platform. 

There, he repeated the same steps marking the spot, adjusting to the environment, and moving forward again.

Step by step, Naruto pushed deeper into Hell Valley.

He knew very well what lay ahead the true core of Hell Valley, the deepest and most dangerous forbidden zone.

That was his destination. That was where he planned to train.

It took him a full ten days to reach the edge of the forbidden area.

On the night of the tenth day, Naruto finally arrived outside the heart of Hell Valley.

At that very moment, deep within the forbidden zone, the Fourth Raikage, A, was striking a wooden post with his bare fists over and over.

This wasn't an ordinary post. It was the Heavenly Thunder Stake, a legendary training tool said to be indestructible.

Each time it was struck with great force, it would release a bolt of lightning equal in power to the blow and send it crashing down onto the one who hit it.

Boom! Boom! Boom! Boom!

Thunder roared as fists and feet landed blow after blow.

This brutal, relentless training… could only be called the work of a monster.

"Uzumaki Naruto!! I'm going to beat you into a pulp!!"

The Fourth Raikage roared, drenched in sweat, as he threw a thunderous punch.

Boom! Boom! Boom! Boom...!!

A massive bolt of lightning struck down, blasting the ground beneath him and leaving a deep crater. But moments later, the damaged earth slowly repaired itself, as if nothing had happened.

"Huff… huff…"

Breathing heavily, Raikage grabbed a towel, wiped the sweat from his muscular body, then casually tossed it aside and got ready to continue training.

"...Huh!?"

He turned slightly and froze. His eyes widened in shock.

A familiar figure was calmly sitting on the steps behind him, quietly watching.

Naruto smiled. "Yo. Long time no see, Raikage."

Raikage's temper flared instantly. "What are you doing here?!"

Naruto shrugged. "Why not? Hell Valley isn't exactly part of Kumogakure, is it?"

Raikage snapped, "I mean how the hell did you get this far without a scratch?!"

Naruto stood up slowly. "That's a long story. But listen, I didn't come here to fight. How about this: you train in the north, I train in the south. We stay out of each other's way?"

Crack!

Lightning exploded around Raikage's body as his rage erupted.

"Don't joke with me! I'm sending you straight to hell!!!"

BOOM!!

He charged forward like a bolt of lightning.

But Naruto didn't flinch. He didn't dodge. He didn't use Shinra Tensei.

Boom!!

He raised his arms and blocked Raikage's punch head-on!

Snap! Snap!

The sheer force of Raikage's attack caused the stone beneath Naruto's feet to crack.

Although surprised by Naruto's strength, Raikage didn't think too much of it. He lunged forward and grabbed Naruto by the shoulders.

"Once I've got you, it's over!!"

Crackle…!!

The lightning around Raikage flared wildly as he roared, lifting Naruto high above his head then slammed him down with full force!

"Ahhh—!!"

BOOM BOOM BOOM!!!

Lightning burst out on impact. Stone steps shattered. Cracks spread across the ground.

Until now, no ninja had ever taken the Lighter Bomb and survived.

Raikage assumed Naruto was finished.

Crack! Crack! Crack!

But suddenly, from the shattered ground, purple lightning surged!

"What!?"

Raikage's eyes widened in shock.

From the rubble, Naruto rose, his hands glowing with a coat of purple lightning. 

He grabbed Raikage's shoulders and in one swift motion, lifted the stunned and furious Raikage over his head!

"That move of yours packs a punch… but now it's my turn!!"

Crackle! Crackle!

With a flash of purple lightning and a powerful shout, Naruto slammed Raikage into the ground!

——Lighter Bomb!!
