Naruto: Creating Immortal Techniques at Six, Shocking Uncle Snake

Chapter 108: [Eternal Mangekyō Training Method] The Fate of the Uchiha! Ishihara's Eternal Eyes!

Even though Fugaku and the others had lost their eyes, they still felt an overwhelming pressure when Ishihara's gaze landed on them.

"What do you want to do now?!"

At this moment, Fugaku wished he could simply die.

Their betrayal of Ishihara had not only yielded no benefits but had also caused catastrophic losses for the Uchiha clan. Countless elite members were dead or injured, plunging the clan from its prime into a critical decline!

Yet, Ishihara seemed unwilling to let them go.

"I just need your help with one more experiment."

With those words, Ishihara created four shadow clones, each taking a position around them and setting up a new barrier to isolate sight and sound completely.

Inside the barrier, only Ishihara, Fugaku, the others, the corpses from the recent experiment, and the sole remaining Mangekyō Sharingan wielder were present.

At that moment, Ishihara also released his control over the shadows, freeing the entire Uchiha clan.

Outside the Barrier

Just as he regained his freedom, Sasuke, furious, rushed toward the barrier. Itachi grabbed him firmly, whispering through clenched teeth:

"Don't act impulsively, Sasuke!"

"Let go of me, Itachi! I need to save Father!"

Sasuke struggled desperately, his cries filled with despair, which pained Itachi deeply.

"Just stay here, please. I don't want to lose you too!"

Sasuke looked up, seeing Itachi's reddened eyes and exhausted expression. His struggles ceased, body frozen.

Itachi had always been a symbol of pride, confidence, and strength in his mind—the very goal he aspired to.

But now, he saw a vulnerable side to his brother. The pleading look in Itachi's eyes broke Sasuke's heart.

Still seething, he no longer resisted. Instead, he asked bitterly, "Itachi, can't you even save Father?"

Itachi looked at the barrier and silently shook his head, lips tightly pressed together.

He wanted nothing more than to save Fugaku, but he was no match for Ishihara. Any provocation could endanger the entire Uchiha clan, as well as Sasuke.

He couldn't take that risk.

Seeing this, Sasuke's eyes filled with tears as he glared at the barrier, vowing in his heart.

"Strength! I will gain immense strength! And then, I'll kill that man!"

Ishihara's image was etched deeply in his mind.

Mikoto stood silently, staring blankly at the barrier, her eyes red and filled with unspoken sorrow.

The entire Uchiha clan was the same. No one cursed or expressed anger; they simply stood there, looking at the barrier, lost and directionless.

Inside the Barrier

Without speaking, Ishihara organized his thoughts and prepared himself.

He then looked at Fugaku and the others.

"You're aware of the Eternal Mangekyō Sharingan, aren't you?"

Fugaku and the others shuddered, raising their heads in astonishment to face Ishihara.

They couldn't fathom how Ishihara knew about such a highly classified matter. But an ominous feeling stirred within them.

"Mangekyō Sharingan users begin losing their vision from the moment they awaken it and eventually go completely blind!"

"But there is a way to avoid this fate—by transplanting another person's Mangekyō Sharingan!"

"Of course, the procedure carries certain risks. Besides the rejection reaction, there's also the chance it could destroy a new set of Mangekyō Sharingan."

Upon hearing this, Fugaku and the others were horrified and exclaimed:

"You want to transplant Mangekyō Sharingan eyes into us?!"

"Exactly!"

Ishihara fell silent afterward.

The current stock of Mangekyō samples was limited, so he needed to make some preparations.

He began analyzing in his mind.

["You have analyzed numerous medical ninjutsu techniques and Mangekyō Sharingan details, creating the secret technique Rejection Suppression Technique."]

[Rejection Suppression Technique: Consumes lifespan to mitigate post-surgical rejection in Mangekyō transplants.]

After processing this new knowledge, Ishihara nodded in satisfaction.

This secret technique would suffice.

Inside the barrier, an oppressive silence reigned.

Fugaku and the others were filled with apprehension but also excitement.

If they could successfully attain the Eternal Mangekyō Sharingan, perhaps they might be able to defeat Ishihara!?

However, as they considered it, their excitement faded.

Ishihara had left too deep a scar in their minds. The thought of facing him, even with the Eternal Mangekyō, seemed futile.

They had lost all confidence in the Sharingan.

Resigned, Fugaku and the others waited silently for Ishihara's orders.

"Next, I'll impart a secret technique. If you experience rejection after the Mangekyō transplant, activate this technique immediately to reduce the symptoms."

Seeing their calm acceptance, Ishihara shared the technique with them.

To facilitate rapid mastery, he adjusted the difficulty level of the technique accordingly.

Fugaku and the others quickly grasped it.

Without delay, Ishihara began transplanting the Mangekyō Sharingan eyes into them, implanting foreign Mangekyō eyes one by one.

"Aaah!"

The four of them screamed in agony after the transplants, with even the barely alive Hirako convulsing violently.

Blood flowed incessantly from the areas around their transplanted eyes.

"Damn, this is the worst-case scenario!"

Ishihara's face darkened.

Rejection reactions varied; mild cases could be managed with medication, but Fugaku and the others were exhibiting acute rejection—an extremely dangerous situation!

He barked, "Activate the technique immediately!"

Fugaku and the others, sensing death's approach, started channeling the secret technique, even Hirako trembling as he followed suit.

Ishihara saw their life forces being drained at a rapid rate, but the rejection symptoms were indeed diminishing.

Eventually, they vanished completely!

And then, subtle changes began to unfold.

"Hm!"

Ishihara had been closely observing the internal state of the four individuals, and at this moment, he immediately noticed an anomaly.

In his understanding, the Mangekyō Sharingan acts as a special converter, transforming chakra received from a specific organ into something even more unique. However, the Mangekyō itself is also composed of cells, which means it contains its own chakra. This chakra flows through the chakra pathways surrounding the special organ, consequently influencing it.

What Ishihara observed was that the chakra generated within the Mangekyō was beginning to interact with the chakra produced by the special organ within Fugaku and the others. When the chakra refined by the special organ entered the Mangekyō Sharingan, the chakra pathways inside the Mangekyō, along with the associated structures like the optic nerves, began to be strengthened.

Even more astonishing to him was the fact that the chakra refined by the Mangekyō, when it entered the special organ, seemed to stimulate a second phase of development within the organ. No, it wasn't just development—it was a process of enhancement and evolution!

Ishihara's eyes widened in shock as he carefully observed the special organ. He confirmed that it was indeed strengthened. Both its size and its chakra production capacity had undergone a qualitative transformation. Although the effect was weak due to the lack of compatibility with the Mangekyō Sharingan, Ishihara could still perceive it clearly.

More importantly, when the chakra produced by the enhanced organ re-entered the Mangekyō Sharingan, it actually reduced the erosion of the Mangekyō. There was even a faint strengthening effect!

Holding his breath, Ishihara heightened his perception to its maximum, unwilling to miss a single detail. Soon, he discerned something even deeper.

"The evolution from Mangekyō to Eternal Mangekyō Sharingan appears to be a mutual enhancement between the Mangekyō and the special organ," he mused. "But fundamentally, it's actually a transformation occurring between the chakra of the Mangekyō and that generated by the special organ."

"As long as either the Mangekyō Sharingan or the chakra within the special organ undergoes a transformation, a positive feedback loop can be established. This would allow mutual strengthening, which would ultimately lead to the evolution into the Eternal Mangekyō Sharingan."

Ishihara became thrilled, knowing he could achieve this with his mastery of Yin-Yang Release.

[You have analyzed the drawbacks of the Mangekyō Sharingan and deciphered the entire process and principles of its evolution. You have created the Secret Technique: Eternal Mangekyō Sharingan Training Method]

[Eternal Mangekyō Sharingan Training Method: Once the Mangekyō is activated, use Yin-Yang Release to simulate chakra that can stimulate a qualitative transformation in either the special organ or the Mangekyō Sharingan, thereby establishing a positive feedback loop and evolving into the Eternal Mangekyō Sharingan]

After processing the information in his mind, Ishihara let out a long breath. He had been correct—simulating the appropriate chakra would indeed enable the Mangekyō Sharingan to evolve into the Eternal Mangekyō Sharingan!

Thud! Thud! Thud!

The sound jolted Ishihara back to reality. When he looked up, his brows arched in surprise. Fugaku and the others had turned into frail, white-haired old men, skin hanging loosely over their emaciated frames, barely clinging to life. Their secret technique had ceased, not because they wanted it to, but because their bodies could no longer sustain it—they were completely drained.

"Why don't you resist?" Ishihara asked, a fleeting thought surfacing in his mind.

Fugaku's face was etched with bitterness, yet he remained silent. Though the secret technique had reduced the internal rejection, they had only inched slightly closer to the Eternal Mangekyō Sharingan. They were still an unfathomable distance away from truly achieving it, and the rejection persisted.

They weren't resisting because they couldn't.

"We only hope that, considering our efforts in aiding you with this experiment, you might spare the Uchiha clan," Fugaku rasped, his voice frail and pleading as he looked at Ishihara with eyes full of despair. It was a sight that could stir one's heart, but Ishihara remained unmoved.

"My intentions for handling the Uchiha are my own; it's not for you to worry about," Ishihara replied coldly.

Fugaku sighed, seemingly having expected such a response, and asked one last request, "Since we're on the brink of death, could we say a few final words to our clansmen?"

Ishihara nodded and released the barrier.

Immediately, the sight of Fugaku and the others in their dire state met the eyes of the Uchiha clan members waiting outside.

A wave of muffled sobs spread among the women, who, though fearful of Ishihara, couldn't help but cry quietly upon seeing the elders in such a wretched state.

"Father!" Sasuke cried out, horrified, as he rushed forward but found himself at a loss for what to say.

Fugaku, trembling, lifted a hand to pat Sasuke's head. "I'm sorry, Sasuke. I won't be able to be with you from now on."

Turning to Itachi, Fugaku's mouth opened, his aged face filled with regret. "If possible, the future of the Uchiha will rest on you."

Itachi nodded somberly, aware of his father's meaning, for none knew what Ishihara's ultimate intentions for him were. Fugaku cast a remorseful glance at Mikoto, who stood silently by his side with tear-streaked cheeks, steadying him.

Then, he faced the mourning clansmen, his heart heavy with grief.

"I apologize, everyone. It was my poor decisions that led the Uchiha to this point."

"As the head of the Uchiha, my final command is this: the Uchiha clan must swear lifelong loyalty to Lord Ishihara, never defying his orders. Do you hear me?"

His hoarse voice resonated with bitterness, but the clan members remained silent, their hearts burdened by frustration, anger, resentment, and helplessness as they watched Fugaku.

The honor of the Uchiha kept them from complying easily.

Fugaku looked to Itachi, his eyes pleading. "Itachi."

Drawing a deep breath, Itachi forced out, in Sasuke's shocked gaze, "I swear to serve Lord Ishihara loyally for life and will never disobey his orders."

Fugaku gave a nod of relief. Itachi had finally matured, though the path had been painful.

Fugaku then turned to others in the police force, calling them out one by one.

"Ryota!"

"I swear to serve Lord Ishihara loyally for life and will never disobey his orders."

"Shinji!"

"I swear to serve Lord Ishihara loyally for life and will never disobey his orders."

"Hanako!"

"I swear to serve Lord Ishihara loyally for life and will never disobey his orders."

"Ryohei!"

"I swear..."

One by one, with tear-filled eyes, the Uchiha clansmen raised their voices in reluctant submission before bowing and kneeling. Finally, the entire Uchiha clan knelt in dead silence before Ishihara.

Fugaku, Inaho, Hirako, and the nameless Mangekyō wielder all knelt, tremulously, before Ishihara as well.

"Lord Ishihara," they uttered as death claimed them.

Fugaku Uchiha was gone.

Inaho, Hirako, and the nameless Mangekyō user were gone as well, having died kneeling before Ishihara. The entire Uchiha clan dissolved into tears.

In the distance, the battle between the Nine-Tails and the Third Hokage had reached its peak.

Standing on the rooftop, Ishihara watched everything in silence, showing no emotion.
