Experiment

"Anything inside my body can be brought under Absolute Control?"

At the thought, Naruto's heart began to beat faster.

In his previous life, he had been an ordinary person living in a world without supernatural powers. Though his Absolute Control was incredible, it still broadly fell within the realm of a biological miracle.

Developing his brain, controlling his body, accelerating healing—at most, those were simply the ultimate form of physical control.

Naruto had always assumed that was probably the limit of this ability.

In his previous world's worldview, an ability to directly interfere with external things through willpower simply did not exist, so Naruto had never considered that possibility.

But after crossing into the Shinobi World, things were different.

There was Chakra that defied physics, Kekkei Genkai that could twist space and time, Rinne Rebirth that could revive the dead, and ancient ancestors who could fall from the moon.

In this world with Chakra, he might have underestimated the true nature of Absolute Control from the very beginning.

"If it truly is Conceptual Level Absolute Control..."

Naruto slowly lowered his hand. His brows tightened slightly before gradually relaxing.

"Then I need to reassess what path I should take in the future."

From the time he awakened until now, Naruto's overall plan for himself had been relatively conservative.

He would keep a low profile, secretly practice ninjutsu to grow stronger, avoid provoking beings on the level of the Ōtsutsuki, and use his foreknowledge of the original plot to avoid risks whenever possible.

But if the essence of his ability was conceptual, then the ceiling of his entire development path had been redefined.

Before, he had considered accumulating combat power, combining ninjutsu, and building a team. Now, he needed to plan an entirely different path.

Countless thoughts flared to life in Naruto's mind like exploding fireworks, each one worth taking the time to explore.

Then Naruto forcibly pushed down every swelling thought.

There was no use overthinking it. No matter how beautiful a hypothesis was, it needed experimental verification.

And right now, a ready-made test subject stood before him.

Snap!

Naruto turned to look at the Nine-Tails and raised his hand to snap his fingers.

The Nine-Tails' body instantly regained its freedom.

Its massive body staggered slightly at the sudden return of control. Its nine tails instinctively flung out behind it, slamming into the iron bars with a series of dull impacts.

The Nine-Tails panted heavily. In a brief moment, confusion, shock, anger, and a trace of fear it refused to acknowledge passed through its crimson eyes.

"Uzumaki Naruto, what did you just do to me?"

The Nine-Tails' voice remained deep and fiercely imposing, but Naruto could hear the faint instinctive unease in it when facing the unknown.

"Kurama, calm down."

Naruto raised one hand in a soothing gesture, his tone becoming steadier. "I need you to cooperate with me in an experiment."

The Nine-Tails narrowed its eyes warily.

"What are you trying to do now?"

The Nine-Tails unconsciously drew its tails back, and its enormous fox body scooted two inches backward.

The strongest Tailed Beast, the one that struck fear throughout the entire Shinobi World, had instinctively tucked its butt back just now?

What hadn't the Nine-Tails seen in its life?

It had been pinned to the ground and beaten by Hashirama Senju's Wood Release, walked like a dog by Madara Uchiha using the Mangekyō Sharingan, sealed inside one Jinchuriki after another, and torn in half by the Reaper Death Seal before being locked in a cage for decades.

Not once had it accepted defeat after losing, and not once had it truly felt fear from the depths of its heart.

But that feeling just now—its entire body no longer obeying its will, while it sensed no external force invading it at all—had genuinely frightened the Nine-Tails.

Naruto smiled, his tone casual. "Don't be nervous. You just need to release all your Chakra at me."

The Nine-Tails froze for a moment.

"That's it?"

Naruto nodded.

The Nine-Tails fell silent for a moment, the ferocious expression on its face replaced by an indescribable confusion.

It had thought Naruto would make some even more outrageous demand, such as forcing it into complete submission or making it hand over all its Chakra for permanent control.

Yet the experiment he mentioned was merely asking it to release Chakra.

"Fine."

The Nine-Tails agreed with almost no hesitation. "Then make sure you can take it."

"This is the Chakra that has accumulated over the years from eroding the seal. It's far more than the little bit you used before."

The Nine-Tails' reason for agreeing was simple: Chakra was the one thing it did not lack.

From the first day it had been sealed inside this blond brat, its Chakra had continuously and slowly seeped through the seal, leaking bit by bit through the gaps in the bars and mixing with Naruto's own Chakra.

It did not care about giving up some of it. If the brat could not withstand it and had his will swallowed by its Chakra, the seal would become even easier to break through.

Naruto took a deep breath and prepared himself.

The next second, a torrent of Chakra far greater than any before erupted from the Nine-Tails' body.

Dark red Chakra surged out from the gaps in the cage like floodwaters bursting through a dam, carrying an icy, bone-deep will of hatred as it instantly flooded Naruto's entire body.

The amount and density of this Chakra were completely incomparable to what he had experienced in the Ice Crystal Magic Mirror Formation.

If last time had been a trickling stream, this time was a mountain flood.

In the real world, Naruto's body was completely enveloped in a deep crimson Chakra aura.

The Chakra was so concentrated that it formed a visible Chakra cloak around his body.

His clothes fluttered without wind under the impact of that immense power. His golden hair stood on end, and the ground beneath his feet cracked inch by inch beneath the pressure of the leaking Chakra.

One tail condensed behind Naruto, slowly swaying behind him. Every swing left a searing afterimage in the air.

Then came the second.

The third.

The fourth.

In moments, four dark crimson Chakra tails unfurled behind Naruto like four burning banners.

The shattered stones on the ground trembled into the air under the pressure, slowly revolving around his body.

Birds in the forest scattered in alarm, and even the distant stream rippled with unnatural rings under the radiation of that power.

Tailed Beast Form

Four-Tails Mode

This was the form Naruto had entered many times in the original story when he lost control in anger. It possessed immense destructive power, but the price was that the Nine-Tails' will of hatred eroded his reason every second.

Normally, a Jinchuriki who could remain conscious in this state would already be considered exceptionally gifted.

Yet Naruto's eyes remained azure blue.

He lowered his head to examine his body, feeling the will of hatred wildly eroding him, then shook the four tails behind him.

The tails obediently moved according to Naruto's will. The second one on the left swung left, the first one on the right curled upward, and all four tails obeyed him even better than his fingers.
