As the light flickered, an indescribable mental wave began to surge through Roy's mind, as if countless pieces of information and power were being awakened and merged.
"This feeling is truly wonderful."
Roy felt a slight itch in his eyes, and then, black tomoe silently appeared in both of his eyes, the entire eye turning crimson in an instant.
[Reward has been distributed.]
The system notification echoed in Roy's mind.
So this is the Sharingan?
Roy gently closed his eyes, feeling that mysterious power.
Yet, he appeared somewhat calm.
Given his current strength, while the Sharingan's abilities were peculiar, they seemed too insignificant in his eyes.
"However, there might still be a way."
Roy suddenly smiled, a confident gleam shining in his eyes.
He began to continuously mobilize the power within him.
The power of Yin, sourced from the spiritual energy that governs imagination, and the power of Yang, sourced from the physical energy that governs life.
Asura, the second son of the Sage of Six Paths, inherited his father's Yang Release, granting him remarkable abilities like auto-recovery, while Indra, the eldest son, inherited Yin Release, mastering powerful illusions and manipulation.
These two powers, Yin and Yang, opposed yet interdependent, formed the cornerstone of this world.
Roy was neither Asura nor Indra, but from the Divine Tree remnants, he had obtained the power of Wood Release, which not only merged the essences of the two Kekkei Genkai, Water and Earth, but also contained the mystery of the Divine Tree's power and the strength of Yang Release.
In terms of quality, this power was not inferior to Hashirama Senju's Wood Release.
As long as the Divine Tree remnant continued to grow, his Wood Release could very well reach, or even surpass, the level of Hashirama Senju.
At this moment, the Yang Release power also obtained from the Divine Tree remnant was constantly surging through Roy's left eye, washing over the Sharingan. This warm, powerful force nourished every part of the Sharingan.
As Yin and Yang forces converged, a peculiar sensation suddenly arose, causing Roy to narrow his eyes.
If anyone had been standing before him at that moment, they would have clearly seen three tomoe spinning continuously in Roy's left eye.
However, for Roy, this was only the beginning.
"Just a Three-Tomoe Sharingan? That's not enough," he muttered to himself.
For him now, even a Mangekyō Sharingan would only serve a supporting role, far from satisfying his pursuit of power.
What he needed was something stronger, something more mysterious.
Roy's gaze fell upon the half-tailed severed from Shukaku, and a smile tugged at the corner of his mouth.
He reached out, picked up the half-tail, and without hesitation, threw it towards the Divine Tree remnant beside him.
Having been carefully cultivated by Roy over this period, the Divine Tree remnant had grown somewhat larger, the entire tree looking even more sinister, as if containing endless darkness and evil.
The moment the half-tail touched the Divine Tree remnant, the tree branch seemed to sense something, trembling violently, appearing extremely agitated.
It actively devoured the One-Tail's chakra, like a starving beast feasting on a delicious meal.
Roy smiled as he continuously channeled his own chakra into the Divine Tree remnant, while the remnant ceaselessly fed this power back to him.
Under the influence of this power, vast amounts of natural energy began to gradually gather around Roy.
This power was strong and mysterious, filling Roy with immense anticipation.
No one knew how long it took, but finally, the Divine Tree remnant completely absorbed the chakra from the half-tail and then actively entered a dormant state.
By then, Roy had already awakened from his training. His Observation Haki sensed everything around him, a satisfied smile on his face.
"What a pity. I was hoping to try and catch that guy, Black Zetsu."
Roy muttered to himself, a hint of regret in his voice.
He had originally intended to use this opportunity to see if he could lure out Black Zetsu, who lurked in the shadows. After all, that guy knew far too many secrets and posed a huge threat to Roy.
But this time, his plan did not succeed; Black Zetsu did not appear as he had hoped.
"Still, I've gained a lot this time."
Roy felt the natural energy surging around him, a force as profound and turbulent as the ocean.
He slowly closed his eyes. Suddenly, he pressed his palms together, interlacing his fingers.
At that moment, it was as if an invisible force stirred the heavens and earth. Endless natural energy began to converge frantically, drawn by an unseen giant hand, coalescing into a massive funnel shape that pierced the clouds.
This power blotted out the sky and covered the sun, shrouding everything around in a hazy light.
Under this overwhelming force, countless natural creatures seemed to sense some form of pressure, some bowing their heads, others looking up, their eyes filled with awe and terror, as if facing the most sacred existence between heaven and earth.
Meanwhile, far away in Konoha Village, as Jiraiya strolled through the village, a sudden inexplicable palpitation rose in his heart.
He looked up into the distance, a flicker of confusion in his eyes.
He had sensed a disturbance in the natural energy. The sheer magnitude and intensity of the power made him frown involuntarily.
Yet, the possibility of Sage Mode was quickly dismissed from his mind. After all, such vast natural energy, in his view, was beyond any human's capacity to control.
At the same time, within Roy, earth-shattering changes were taking place.
He let out a soft shout.
As his voice faded, the gathered natural energy began to take shape within him.
In that moment, Roy seemed to merge with nature. Every cell in his body resonated with the world around him, as if he had become a part of this world.
A dazzling, circular red mark appeared distinctly on his forehead—a mark of natural power, the symbol of Sage Mode.
It shimmered with a mysterious light.
"This is… Sage Mode."
But it wasn't over.
He keenly sensed an unusual sensation in his eyes.
With a thought, he quickly mobilized the Yang Release power, now incredibly active due to Sage Mode, and it surged instantly into his Three-Tomoe Sharingan.
Under this force, his body became a massive furnace where various powers intertwined and collided.
Finally, at a certain moment, the Yin Release power that had been lying dormant within him erupted violently.
In that instant, Roy's eyes seemed to lose control, spinning wildly. A flash of dazzling red light streaked across his pupils, and then, an unprecedented, mysterious pattern began to emerge in his irises.
