Naruto: Reincarnated as Sasuke Uchiha with Perfect Talents.

"Impossible!"

"Absolutely impossible, how can this be?"

"This is absolutely impossible; how could he master Sage Mode?"

The White Snake Sage was completely baffled.

Clearly, Sasuke already possessed the special Sage Transformation physique, so how could he also master the Ryūchi Cave's Sage Mode?

This was fundamentally impossible.

The chakra generated by Sasuke's unique physique was inherently different from the chakra produced by the Ryūchi Cave's Sage Mode.

In other words, it was akin to two distinct machines operating within one body.

The energy they produced should be as incompatible as water and fire.

Even if Sasuke, through sheer willpower, managed to master the Ryūchi Cave's Sage Mode, it was inconceivable for him to perpetually suppress his body's natural instincts.

No matter how strong his will, it would inevitably falter at some point.

The moment his focus slipped, his body would instinctively start generating chakra.

At that point, the conflict between the two energies would cause Sasuke's body to react violently, akin to an overinflated balloon.

Even if his body didn't explode outright, there would still be consequences. The clash between the two types of chakra would inevitably cause issues.

If Sasuke lost control, the chakra he naturally produced might remain unaffected, but the Sage Chakra generated by the Ryūchi Cave's Sage Mode would be a different story.

If that Sage Chakra became uncontrollable, what would the outcome be?

The results would inevitably be either a serpentine transformation or turning into stone.

This was the inevitable consequence of losing control over Sage Chakra.

The truth was, the chakra produced by the special Sage Transformation physique lacked the overwhelming power of Sage Mode for one fundamental reason:

Sage Mode, at its core, was a jutsu a technique.

This technique combined natural energy with physical energy to create a unique form of power. While Sage Chakra could be used to perform ninjutsu, it was, strictly speaking, the result of a technique.

By contrast, the chakra generated by Jūgo's special Sage Transformation physique did not rely on any jutsu.

Without the enhancement provided by a jutsu, its power was naturally somewhat weaker.

However, it also lacked the terrifying consequences of losing control that came with Sage Mode.

The White Snake Sage observed Sasuke, who was voraciously absorbing natural energy. The fluctuations of Sage Chakra he condensed grew increasingly powerful.

But to claim that Sasuke had mastered Sage Mode? There were no visible signs.

For instance, Sasuke had not grown horns on his head.

Not even a change in his complexion none of the hallmark characteristics of the Ryūchi Cave's Sage Mode were present.

'What exactly is going on with this kid?'

In sacred places like Ryūchi Cave and Mount Myōboku, mastering Sage Mode typically led to some physical transformations.

Even Naruto, after mastering the so-called perfect Sage Mode, displayed traits like toad-like eyes and eye shadow.

This was a characteristic of techniques only jutsu brought about such changes.

In contrast, Jūgo's Sage Transformation resulted in drastic changes in appearance. However, as the White Snake Sage pointed out, it was merely a semi-finished Sage physique.

A perfected Sage physique should resemble individuals like Ashura or Hashirama. When they activated Sage Mode, their appearances hardly changed at all.

However, within Sasuke's body, a peculiar transformation was unfolding.

After Sasuke had flawlessly mastered the Ryūchi Cave's Sage Mode, he used both his willpower and the Curse Mark's assistance to suppress the instinctual reactions of his Sage Transformation.

As Sasuke gained control over Sage Mode, the Curse Mark began to undergo unexpected changes.

The Curse Mark itself was a technique based on Jūgo's unique physique.

However, because Orochimaru had never mastered Sage Mode, his creation was merely an imitation at best.

To be precise, the Curse Mark was an idealized attempt by Orochimaru to replicate Sage Mode, combined with Jūgo's Sage Transformation a creation born of his lofty ambitions.

Although it was ultimately successful, the Curse Mark was essentially an empty shell.

It only managed to function because of Jūgo's unique physique, enabling it to absorb a small amount of natural energy and generate pseudo-Sage Chakra.

Still, Orochimaru's genius was undeniable.

Even without mastering Sage Mode, he had constructed a framework for it.

Now, something miraculous was happening. When Sasuke perfectly mastered the Ryūchi Cave's Sage Mode, his body should logically exhibit at least some changes.

And this transformation naturally manifests as serpentization...

However, the Curse Mark seemed to begin adapting to the energy flow mechanism of the Ryūchi Cave's Sage Mode.

It seamlessly integrated this energy flow mechanism into itself.

In other words, activating the Curse Mark mode now equated to activating the Ryūchi Cave's Sage Mode.

Yet, the Curse Mark contained another significant aspect: the power of Jūgo's Sage Transformation.

With the new energy flow mechanism incorporated, the Curse Mark also altered the way the Sage Transformation power operated.

If the previous autonomous absorption of Sage Chakra was merely an instinctual response of the body, a passive ability,

then the active ability Sasuke had now learned (Sage Mode) had fundamentally changed the passive ability (Sage Transformation).

The two powers essentially merged into one.

The difference lay in the fact that the Sage Chakra generated by the special Sage Transformation physique had been stripped of the concept of technique.

However, it retained the effects of the technique.

This became the primary reason why Sasuke displayed no outward transformations.

At the same time, the Wood Release Kekkei Genkai accelerated Sasuke's absorption of natural energy.

This energy was then passed to the Curse Mark for the refinement of Sage Chakra.

If Naruto's Sage Mode relied on the Nine-Tails for assistance, and Kabuto's Sage Mode depended on a symbiotic White Snake for support,

then Sasuke's current Sage Mode similarly had the aid of Wood Release.

While Wood Release differed from the Nine-Tails and the symbiotic White Snake,

its autonomous energy manipulation capabilities were not much inferior to theirs.

However, since Sasuke's Wood Release Kekkei Genkai is currently only in its initial stage, the absorption speed is significantly slower. But with Sasuke's active consciousness added into the process,

the recovery speed is greatly enhanced.

Opening his eyes, a brilliant light burst forth from Sasuke's gaze.

The skin on his body rapidly underwent the transformation of the Curse Mark,

instantly entering the third level of the Curse Mark, which is the Sage Transformation state.

A massive amount of natural energy was frantically absorbed, Sage Chakra refined, and intense waves of energy were released.

The vibrations from the Sage Chakra were so powerful that even the air around him suddenly and violently shook.

Sasuke looked at his own hands, feeling the immense strength of the activated Sage Mode.

"So this is... the power of Sage Mode!"
