Mangekyo Right Eye!

Yo raised his right hand and aimed it at his own left eye socket.

No anesthetic!

No hesitation!

He dug in hard!

"Ngh..."

A searing pain exploded from the optic nerve, sweeping through half his brain. Blood streamed down between his fingers and along his cheek.

Yo sucked in a cold breath, extracted his original eyeball intact, and placed it into a nutrient solution prepared in advance.

Then he picked up a Three Tomoe Sharingan and set it into the eye socket.

Life force surged forth once more, frantically repairing the damage.

This process was several times longer and more agonizing than the arm transplant.

Fine cold sweat beaded on Yo's forehead, and his body trembled slightly.

Two minutes later, that violent sensation of restoration gradually subsided.

Yo slowly opened his left eye.

Chakra flowed smoothly.

Visual enhancement was stable.

Neural connections were solid.

No rejection!

The three tomoe spun.

An unprecedented ability to track motion surged up.

Yo could see the subtle trajectories of dust particles drifting in the air, the faintest tremors of leaves outside the window.

Clearly!

The Three Tomoe Sharingan...

Transplant successful!

"Step one, complete!"

Yo muttered to himself.

"Now I can transplant the Mangekyo!"

Without further hesitation, Yo gouged out his right eye and placed the original eyeball into another prepared solution bottle.

Better to keep the original eyes preserved—if something went wrong later, he could still transplant them back.

No delay!

Yo opened the small bottle, took out Shisui's right Mangekyo eye, and inserted it into the empty right eye socket.

Hum!

In an instant, an entirely different sensation arrived.

An icy, powerful dojutsu force surged backward through the newly formed neural connections, crashing straight into Yo's brain.

Unlike the docile nature of an ordinary Sharingan, this Mangekyo was like a savage beast trying to choose its master and devour him!

A violent sense of rejection erupted, accompanied by a burst of immense dojutsu power.

Fragments of memories that did not belong to Yo suddenly flashed.

Instant darkness, the sharp pain of a backstab, a trust entrusted to a close friend, the cold and despair of falling into a river...

"Hmph... a coward in life, and still restless in death?"

Yo snorted coldly, immediately focusing all his spirit and will to forcibly suppress this residual mental assault.

The life force of the Sage Body also became his firmest backing.

While repairing the damage, it quickly soothed those restless mental echoes.

At last...

That defiant will gradually faded. The icy dojutsu power obediently merged and bonded with his chakra.

The stinging in the eye socket slowly turned into a warm sensation of fusion.

Repair complete!

Yo regulated his breathing, calming his somewhat disordered chakra, then opened both eyes.

Still in Three Tomoe form!

Yo willed it.

The three tomoe rapidly connected, forming a complex and elegant four-pointed windmill pattern.

It was precisely the unique appearance of Uchiha Shisui's Mangekyo Sharingan.

Yao's mind stirred slightly as he attempted to inject chakra into this newly acquired Mangekyo Sharingan, carefully sensing the unique power lurking deep within it.

Soon, a clear "concept" fed back to him:

Kotoamatsukami!

This right eye indeed housed the ocular jutsu Kotoamatsukami!

It was a terrifying Illusion Technique that twisted reality and altered will!

But unfortunately, at this moment, Kotoamatsukami was in a cooldown state.

The cooldown cycle was despairingly long; based on his current perception, it would not be unsealed anytime soon.

Yao was not surprised by this result. Danzō had used Kotoamatsukami, so naturally it couldn't be used immediately.

He paid it no mind.

Only a worthless character like Danzō, who possessed little power of his own, would think of using Kotoamatsukami to control others.

He, Uchiha Yao, possessed immense power himself; there was absolutely no need to use Kotoamatsukami!

It could be said.

Kotoamatsukami, among the many Mangekyo ocular jutsus, was the most useless one to Uchiha Yao.

What Yao truly valued was the Susanoo inherent to the Mangekyo!

But the problem was, to activate Susanoo, both eyes were required.

Therefore, he had to obtain Shisui's left Mangekyo eye!

"Itachi!"

"Uchiha Itachi!"

"I hope you'll appear in Konoha, just like in the story. I'm determined to get Uchiha Shisui's left eye!"

Yao murmured softly, temporarily suppressing this thought. He blinked, beginning to adapt to the changes in his eyes.

Going from ordinary eyes to suddenly having a Three Tomoe and a Mangekyo Sharingan—the change in vision was enormous!

Yao had to hurry and get used to it.

The next day.

The smell of gunpowder and grief lingering over Konoha had not yet dissipated.

An explosive piece of news swept across the entire shinobi world at an astonishing speed:

During the Chūnin Exams, Konohagakure's S-Class Rogue Ninja Orochimaru colluded with one of Konoha's high-ranking officials, Shimura Danzō, the leader of the "Root" division, and allied with the two great ninja villages of Sunagakure and Otogakure to launch a large-scale attack on Konoha!

In this turmoil, the Third Hokage, Hiruzen Sarutobi, who had led Konoha for nearly forty years... fell in battle!

After causing massive destruction, Orochimaru and Danzō successfully escaped.

Konoha issued an S-Class wanted order, hunting down the original S-Class Rogue Ninja Orochimaru and Root leader Danzō across the entire shinobi world.

This news sent earthquake-level shockwaves through the shinobi world.

What was Konoha?

Since its founding by the First Hokage, Konoha had been recognized as the number one great ninja village in the shinobi world, the military pillar of the Land of Fire among the Five Great Nations, with formidable strength.

And the Third Hokage was not only the longest-serving Hokage in Konoha's history but also a legendary figure who had survived two Great Ninja Wars, hailed as the "Professor of Ninjutsu."

He held significant prestige and influence throughout the entire shinobi world.

His fall...

The impact was enormous!

Land of Earth, Iwagakure.

Ōnoki of Both Scales looked at the urgent intelligence scroll in his hands, sitting on the Tsuchikage's chair, silent for a long time.

"That old man Hiruzen Sarutobi... actually died?" Ōnoki muttered to himself, his tone complex.

As fellow Third Generations, Ōnoki and Hiruzen Sarutobi were old rivals, and they held a mutual respect for each other.

And yet...

The Third Hokage had fallen in battle!

Ōnoki's mood was complicated—a mix of some regret for the passing of an old rival, and even more so, a touch of sorrow.

Hiruzen Sarutobi was dead.

What about himself?

After a long moment.

Ōnoki adjusted his emotions and issued orders: "Pass down the order: strengthen patrol levels on the eastern border!"

"Also, increase intelligence squad personnel by thirty percent, with a focus on infiltrating the border region of the Land of Fire and the outskirts of Konoha."

"I want to know every detail of Konoha's current strength, the movements of every Jōnin! Every ounce of power!"

"Yes!"

The war machine of Iwagakure began to turn rapidly.

A large number of ninja skilled in reconnaissance were dispatched toward the Land of Fire.

Ōnoki's calculations were clear: Konoha, having suffered such a heavy blow with its high-end combat power depleted, would inevitably be in internal turmoil.

This was the perfect time to gather intelligence, apply pressure, and even test the borders to seize advantages.

There was no helping it.

After all, the Land of Fire occupied the most fertile lands in the ninja world.
