Chapter 193: Sharingan

A faint green glow appeared in Tonari's palm as he carefully placed his index and middle fingers on his right eye.

The human eye connects to numerous nerves, and even the slightest mistake or damage can result in permanent blindness. Tonari's surgical precision was evident as he performed the procedure on himself.

A sharp, searing pain coursed through him as he removed his eye.

He carefully placed the extracted eyeball into a prepared glass container filled with a nutrient solution.

"I'll need this back later, so I better keep it safe," he muttered.

Blood trickled from the corner of his eye, running down his cheek.

"The pain is no joke. Without anesthetic, cutting the optic nerve feels like hell. And those who treat Sharingan like plug-and-play USB drives? Absolute maniacs," Tonari grumbled as he prepared the Sharingan for transplantation.

After sterilizing the Sharingan, he carefully inserted it into his empty eye socket. Activating his medical ninjutsu, he began reconnecting each nerve and blood vessel, one by one.

The process was meticulous. He could feel the Sharingan adjusting to its new environment.

Once the blood vessels were connected, he noticed a brief but distinct feeling of rejection—an instinctual pushback from the foreign eye. However, this sensation quickly subsided.

If Tonari hadn't been paying close attention—enhanced by his expertise as a medical ninja—he might not have noticed it at all.

With the optic and chakra-conducting nerves successfully connected, Tonari began testing the eye.

At first, everything was blurry. But soon, a faint light appeared, shapes formed, and details gradually became clear.

The clarity was astonishing.

His new right eye's vision was far superior to his left. It was like comparing an advanced high-tech camera to a basic lens— the difference was stark.

Even more remarkable was the Sharingan's dynamic visual capabilities.

Tonari had spent years training his perception and reflexes to master high-speed combat. However, with the Sharingan, his ability to track movements felt exponentially heightened, far beyond his natural limits.

The black tomoe within the crimson iris began spinning rapidly as he directed chakra into the Sharingan.

"Even at just the two-tomoe stage, the boost is significant. Bloodline limits truly are an innate advantage," Tonari mused.

The Sharingan's utility wasn't limited to its visual enhancements. Its potential in genjutsu, especially the specialized illusions unique to the Sharingan, was equally noteworthy.

Unfortunately, without the three tomoe stage, he couldn't fully utilize its ability to replicate jutsu with just a glance.

"The chakra consumption, though... no wonder non-Uchiha struggle with this. Even at two tomoe, the strain is significant."

Fortunately, Tonari's chakra reserves were considerable. For now, the two-tomoe Sharingan's demands were manageable, but he could foresee potential challenges if it evolved further.

"Hm?"

As he continued testing the Sharingan, something unusual caught his attention.

Hidden amidst the countless nerves and vessels in the transplanted eye was a distinct, almost imperceptible neural pathway.

This structure was absent in regular human eyes, and it was so well-concealed that only someone with exceptional focus and expertise could detect it.

"This... this might be the key difference in Uchiha physiology."

Though non-Uchiha could implant and use Sharingan, the absence of this specialized nerve seemed to limit their ability to fully master the eye.

Intrigued, Tonari shifted his focus to the Uchiha cadaver. After hours of meticulous examination and comparison, he identified where the unique nerve connected: deep within the brain's core.

"This must be it—the neural link that triggers the Sharingan's evolution."

Tonari hypothesized that intense emotional stimuli activated this neural pathway, sending feedback to the Sharingan and driving its progression.

"It doesn't affect basic functionality but directly governs advancement. Fascinating."

Tonari scratched his chin thoughtfully.

"For non-Uchiha, even if we replicate this nerve, it won't allow voluntary activation or deactivation of the Sharingan. But..."

A dormant sensation stirred within him.

Acting on impulse, he extended his left hand. A small sapling sprouted from his palm, growing rapidly before his eyes.

Compared to before, Tonari's control over Wood Release had noticeably improved.

"It seems the Sharingan and Wood Release have a synergistic effect. The interplay of Indra's and Asura's bloodlines amplifies their combined potential, reminiscent of the Sage of Six Paths' power.

"If I can successfully integrate more of Hashirama's cells, I might enhance my Wood Release even further."

Tonari made a mental note to explore this possibility in the future.

"For now, this is enough. Time for the final test: Yin chakra infusion."

Dark energy seemed to ripple faintly across Tonari's face as he channeled Yin chakra into the Sharingan.

The tomoe spun furiously, absorbing the energy like a black hole.

"Such hunger," Tonari muttered, feeling the Sharingan greedily consume the Yin chakra.

In a split second, he closed his eyes and entered the sealed space within himself.

Nibi, the Two-Tails, lounged lazily but perked up upon sensing Tonari's presence.

"What did you do to yourself, Tonari? That eye..." Nibi growled, its gaze narrowing as it noticed the Sharingan.

Tonari waved dismissively. "No time to explain. I need all your Yin chakra, now."

Nibi's ears twitched, and it rose to its feet. "You're sure about this?"

"I'm sure."

Without another word, Tonari exited the sealed space.

An immense wave of Yin chakra surged through him, concentrating in the transplanted Sharingan.

The tomoe spun wildly, merging and reforming into a perfect ring.

The transformation was complete—Tonari now possessed a three-tomoe Sharingan.

"Remarkable," he whispered, marveling at the eye's newfound capabilities.

The chakra consumption had increased, but so had the eye's power. The clarity, depth, and responsiveness were unparalleled.

"So it's true. Intense emotional stimuli trigger an Uchiha's innate release of Yin chakra, which catalyzes the Sharingan's evolution. Forcing the process with external Yin chakra achieves the same result."

Tonari stared at his reflection, the crimson eye glinting with a dangerous allure.

But his thoughts were pragmatic.

"Even with all this power, the risks are immense. For now, this experiment is complete."

He carefully removed the Sharingan and reinserted his original eye, savoring the comfort of his natural vision.

The Sharingan, now preserved in a nutrient-filled vial, rested securely within a storage scroll.

"These eyes are extraordinary. But until the time is right, they'll remain sealed."

Tonari turned his attention to the other two subjects: the Hyuga cadaver and the Third Kazekage's body.

"Let's see what secrets you hold, Kazekage-sama."
