Naruto: Starting as the Third Hokage with Tears in His Eyes

Tsunade gave Nagato a reassuring smile and gestured for him to lie down on the operating table.

Outside the door, in the corridor.

Yahiko paced back and forth anxiously, occasionally pressing his face against the small window in the door, trying to see what was happening inside, but he couldn't see anything.

"Do you think... it will hurt a lot?" He scratched his head, his face full of worry. "It's like getting your eyes replaced! That sounds terrifying."

Xiao Nan sat quietly on the bench, her hands folded on her knees, her fingertips unconsciously folding, unfolding, and folding a small piece of paper repeatedly.

"Lady Tsunade is the best medical ninja," she said softly, as if comforting Yahiko, or perhaps comforting herself.

The operating room doors slowly closed in front of them.

The red "In Surgery" light above the door turned on.

Inside, Tsunade picked up a scalpel that shimmered with green chakra light, looked at Tobirama Senju standing to the side, who had already assumed the role of "chief scientific advisor," and took a deep breath.

"Are you ready, Second Grandfather?"

Tsunade's eyes were sharp and bright.

"We are about to begin creating a new legend."

"..."

Green chakra light gathered at the edge of the scalpel.

Tsunade pressed down on her wrist, the blade slicing into the optic nerve plexus.

Fine beads of sweat rolled down her forehead.

In front of the huge tactical board next to him, Tobirama Senju stood with his arms crossed, his red eyes fixed on the pulsating ripples on the vital signs monitor.

"Pulse is 120. Blood pressure is normal."

Tobirama spoke, his voice steady and efficient, "The right eye optic nerve connection is 80% complete. The rejection reaction is brewing. Prepare to inject a 0.2% concentration of interstitial cell diluent."

"immediately."

Tsunade formed a hand seal with her left hand, diverting her chakra and precisely guiding it through the dropper beside her. The colorless, transparent liquid flowed into Nagato's veins through the tube.

The electrocardiogram emitted a sharp, long beep.

"The rejection reaction has begun."

Orochimaru was rapidly recording data, his long tongue licking his lips, barely suppressing a laugh from his throat. "Sparashi... the collision of two top-tier bloodlines, this body is reshaping its rules, it's incredible!"

"Shut up, Orochimaru. Don't disturb me while I'm performing surgery."

Without even looking up, Tsunade increased her chakra output, and green light completely enveloped Nagato's face.

Tobirama's fingers tapped rapidly on the metal control panel beside him, adjusting the power of the chakra suppressor.

"All data match the theoretical framework. Increase the injection rate to maintain cell viability."

Time stretched out endlessly outside the operating room.

Yahiko paced back and forth in the corridor, wearing the floorboards down until they were almost shiny.

He would occasionally press his face against the small window in the door, trying to see what was happening inside, but he could only see a blurry shadow.

"Do you think... it will hurt a lot?" He scratched his orange hair, looking worriedly at the ninja who was also waiting beside him. "It's an eye transplant! It sounds terrifying."

The Konoha ninja sat cross-legged on the ground, arms crossed, and nodded solemnly: "For a ninja, any surgery carries risks. But you must trust Tsunade, and your master."

Xiao Nan sat quietly on the bench, her hands folded on her knees, but her fingertips unconsciously folded and unfolded a small piece of paper repeatedly, revealing her inner unease.

I don't know how much time passed, maybe a few hours, maybe a whole day.

When the red light during surgery went out, the three people jumped up from their spots almost simultaneously.

The operating room door opened, and a weary-looking Tsunade walked out.

"Lady Tsunade!"

"Tsunade!"

"How is it?"

Tsunade took off her surgical cap, shook her sweat-dampened blonde hair, and finally revealed a relieved smile on her face.

"It's a success."

Two simple words brought life back to the air in the corridor.

Inside the operating room, Tobirama Senju looked at the stable data on the monitoring instruments. His perpetually serious face relaxed, revealing a rare expression of satisfaction.

"The data... is perfect."

Orochimaru closed the notebook and let out a satisfied sigh.

It's so perfect, it's like the birth of a work of art.

Tsunade's superb chakra control brought medical ninjutsu to its pinnacle of precision; while Tobirama's terrifying theoretical framework provided the most solid logical foundation for this operation.

Science and ninjutsu, life and energy, merged in an unprecedented way at this moment. Every piece of data he recorded was like a beautiful movement of music, heralding the birth of a brand new discipline.

So that's how it is. The continuation and evolution of life don't necessarily require forbidden techniques; they can also be achieved through such exquisite optimization.

The path pointed out by Master Hiruzen is indeed full of endless mysteries.

He couldn't wait to bring this data back to Class Zero and begin new research.
