Eye Awakening, Dual Kekkei Genkai!

In front of Nawaki's grave in Konoha.

"You brat!"

As Tsunade frowned, she saw Uchiha Yoru trembling, black flame-like Curse Mark patterns spreading from his neck. The moment he deliberately activated this Curse Mark Sage Body, an endless tide of negative emotions surged in. Yoru's eyes were bloodshot, his heart brimming with murderous intent.

"Not good!"

At that instant, Tsunade finally realized the problem—this brat had awakened some kind of power, and it didn't seem to be the Sharingan.

Yoru let out a muffled groan, pain twisting his face. Seeing Tsunade before him, he steeled himself and released the Curse Mark Sage Body's restraint on his body.

He'd finally caught this chance—the woman in front of him was the number one Medical Ninja in the ninja world.

A shinobi!

Had to be ruthless with himself!

"No way, this is!?"

Under the Mystical Palm Technique, Tsunade instantly sensed the condition inside Yoru's body and couldn't help but be shocked.

"He's awakened some kind of power inside him, causing backlash on his body. Isn't this brat an Uchiha!"

The awakened power wasn't the Sharingan, but another force entirely.

No!

"C-Captain Tsunade... Uchiha Yoru requests deployment to the battlefield!"

Yoru forced out the words hoarsely, enduring the pain, veins bulging on his forehead and neck. The agony of the backlash, along with the surging negative emotions, overwhelmed him.

Under Tsunade's shocked gaze, the bloodshot eyes of this brat, Uchiha Yoru, gradually formed a single black tomoe.

The Sharingan had awakened!

Was it because of what happened to Nawaki, and the pain toward the village and his clan!?

"Shut up, you Uchiha brat."

Tsunade snorted, grabbed him, and vanished from before the Memorial Tablet.

The Senju Clan compound.

When Yoru opened his eyes again, he found himself in a room cluttered with medical equipment. An IV tube was stuck in his hand, the liquid dripping steadily. He opened his mouth hoarsely, and a sharp pain immediately struck him.

"Where is this?"

Yoru's face was twisted in agony, every cell in his body seeming to sting.

"Looks like you're not dead yet, brat."

Across from him, Tsunade, who had been examining a scroll on the table, looked up with a cold snort.

"What... what happened to me?"

Yoru feigned confusion, but Tsunade just snorted again.

"Brat, you got lucky. You awakened two bloodlines at once."

Two bloodlines!

An ordinary ninja might think it was a fantasy, but with Tsunade's knowledge, the ninja world was vast—rare, but not unheard of.

"Bloodlines?"

Yoru seemed to recall something, his expression complicated.

That only irritated Tsunade more. This brat was so stubborn that he'd awakened bloodlines from the shock—two of them, no less. It was her brother who died, and she hadn't awakened anything. Yet this outsider got triggered and awakened? Still... that was very Uchiha.

"Right. Listen, brat—every Kekkei Genkai family has a rare rejection effect, what's called a Bloodline Disease. The Uchiha Clan is no exception."

"Bloodline Disease usually comes from overusing or draining that power, causing irreversible damage to the body over time. Another type is congenital—the body simply can't adapt."

As she spoke these technical terms, a deep thirst for knowledge flickered in Tsunade's eyes. For a Medical Ninja, this was a rare specimen.

"And you, you idiot brat, awakened two bloodlines at once, so your body can't handle it."

At that, Tsunade glanced at Yoru's IV drip and snorted.

"In the entire ninja world, only a handful can brew this Cell Stabilizing Agent. Each bottle is worth a fortune."

Her voice echoed in the room, but Yoru weakly reached for the IV needle, trying to pull it out.

"Brat, what are you doing!?"

"I... I don't have that much money!"

Yoru's weak words claimed poverty, but the hidden resolve in his eyes told Tsunade the truth.

This brat still hasn't given up on throwing his life away on the battlefield.

For a moment, Tsunade's head ached. It seemed like she was the reason this kid had turned out this way.

"Kid, you want to die!"

As Tsunade's cold voice echoed, Uchiha Yoru fell silent, offering no reply.

Seeing Uchiha Yoru like this, Tsunade felt exasperated. Stubborn Uchiha—they gave her a headache.

Her own younger brother's death had actually triggered an outsider's Eye Awakening, and now she had to find a way to keep this kid from seeking death.

Ninjas might lie, but the Uchiha Clan's Sharingan never would.

"The matter of Nawaki ends here. I need you to stay in the Uchiha Clan."

Under Tsunade's cold voice, a glimmer of light seemed to appear in Uchiha Yoru's lifeless eyes. He slowly lifted his head, looked at Tsunade, a hint of hope in his gaze, and rasped:

"Captain Tsunade, are you saying I should investigate the traitor in the Uchiha Clan!"

A pair of blood-red one-tomoe Sharingan stared straight at her. Only by facing it directly could one understand how absurdly stubborn the Uchiha Clan could be.

Tsunade was speechless inside. This kid was really getting carried away, but!

This seemed perfect—she could also plant a pair of eyes in the Uchiha Clan, at least to know everything.

Seeing Tsunade silent, Uchiha Yoru seemed to fill in the blanks himself, a stubbornly determined expression appearing on his face.

"For the Leaf! Captain Tsunade, rest assured, I will never allow anyone to betray the village!"

Right!

At that moment, Tsunade let out a long sigh inwardly. She finally understood the Uchiha recorded in her clan's documents.

Stubborn Uchiha!

Under his resolute expression, Uchiha Yoru secretly breathed a sigh of relief as he looked at the IV drip beside him.

Finally latched onto a big shot. This gene Stabilizing Agent is too precious. Thankfully, everything went smoothly.

As long as Tsunade was around, he was confident he could fully merge this bloodline in the next five or six years.

"Lie down. I'm going to thoroughly study your other bloodline now."

Under Tsunade's cold voice, she seemed to acknowledge his spy plan.

Uchiha Yoru remained silent, lying on the hospital bed, but inwardly he breathed another sigh of relief.

He had won this gamble.

Not only had he gained Tsunade as a powerful ally, but he had also awakened the Sharingan.

Sure enough, his natural talent wasn't bad—he had the aptitude for Eye Awakening, and he'd opened it at the critical point of negative emotions from this Curse Mark.

Even if he had lost the bet, he still had Mikoto as a fallback.

"Kid, this bloodline of yours has strong rejection. If you misuse it, don't be surprised if you don't live a few more years."

Tsunade, examining Uchiha Yoru's body, frowned and spoke calmly, but Uchiha Yoru remained silent, as if still immersed in Nawaki's death.

Watching this, Tsunade's head throbbed. Reasoning with an Uchiha was impossible.

"This unknown bloodline is latent inside you, but due to the rejection effect, your body's self-protection mechanism has formed it into a Curse Mark Mode on your neck..."

Tsunade changed the subject, starting to talk about Uchiha Yoru's unknown new bloodline. Especially when she got to this part, a desire to explore flickered deep in her eyes.

Bloodline research!

The ninja world had never stopped. As the strongest Medical Ninjutsu user in the ninja world, Tsunade had finally stumbled upon an unknown research subject. To say she wasn't tempted would be a lie.
