Konoha, in front of Nawaki's grave.
"Kid!"
As Tsunade frowned, Uchiha Yoru's body trembled, and black, flame-like cursed seal markings spread from his neck.
When he deliberately triggered this cursed seal Sage Body, a torrent of negative emotions instantly surged. Yoru's eyes became bloodshot, and his heart was filled with endless killing intent.
"Not good!"
At this moment, Tsunade finally realized the problem. This kid had awakened some kind of power, and it didn't seem to be the Sharingan.
Uchiha Yoru groaned, a pained expression on his face. Seeing Tsunade in front of him, he hardened his heart and released the restraints on his body from the cursed seal Sage Body.
He had finally seized this opportunity, and the person in front of him was the number one medical ninja in the world.
A ninja! You have to be a little ruthless to yourself!
"Not good, this is...?"
Using her Mystical Palm Technique, Tsunade instantly detected Uchiha Yoru's condition and was shocked.
"He's awakened some kind of power within his body, which is causing a backlash. Isn't this kid an Uchiha?!"
The power he awakened wasn't the Sharingan. Instead, it was another power.
No, wait!
"Cap... Captain Tsunade, Uchiha Yoru requests to go to the battlefield!"
Uchiha Yoru endured the pain and said in a hoarse voice. At the same time, the veins on his forehead and neck bulged. The pain of the backlash, combined with the surge of negative emotions, was overwhelming.
Under Tsunade's shocked eyes, the kid, Uchiha Yoru, had his bloodshot eyes gradually begin to form a black tomoe.
The Sharingan had awakened!
Was it because of what happened to Nawaki, and the pain between the village and his clan!?
"Shut up, you Uchiha brat."
Tsunade let out a cold snort and grabbed him, disappearing from the Memorial Stone.
In the Senju Clan compound.
When he opened his eyes again, he found himself in a room filled with medical equipment.
With an IV drip in his arm and a bag of liquid hanging and dripping, he tried to speak, but a sudden pain struck him.
"Where is this?"
Uchiha Yoru's face was filled with pain, as if every cell in his body was stinging.
"Looks like you're not dead, kid."
Tsunade, who was sitting at a desk reviewing a scroll, looked up with a cold snort.
"What... what happened to me?"
Uchiha Yoru feigned a confused expression, but Tsunade just snorted coldly.
"Kid, consider yourself lucky. You've actually awakened two bloodlines at the same time."
Awakening two bloodlines!
An ordinary ninja might think it was a fantasy, but to Tsunade's knowledge, in a world as vast as the ninja world, while it was rare, it wasn't impossible.
"Bloodline?"
Uchiha Yoru seemed to have thought of something, and his expression became complex.
Seeing this, Tsunade became even more annoyed. This kid was truly obsessive. He was so stimulated that he awakened a bloodline, and two at that.
Her own brother died, and she didn't awaken a bloodline, but an outsider got stimulated and awakened one?
But, then again, this was so Uchiha!
"That's right. Kid, you need to know something. Any bloodline clan can have a rare rejection effect, also known as Bloodline Sickness. This naturally happens in your Uchiha clan as well."
"Bloodline Sickness is usually caused by the overuse or overdrawing of this power, which, over time, causes irreversible damage to the body. Another type is a congenital physical incompatibility."
Tsunade spoke in a professional tone, but deep in her eyes was a profound thirst for knowledge. After all, this was an incredibly rare research subject for a medical ninja.
"And you, kid, have a problem with your brain. You awakened two bloodlines at the same time, which caused an incompatibility within your body."
At this point, Tsunade looked at Uchiha Yoru's IV drip and snorted.
"Only a handful of people in the entire ninja world can formulate this kind of cell stabilizer. Each bottle is priceless."
Tsunade's voice echoed in the room, but Uchiha Yoru weakly tried to pull out the IV needle.
"Kid, what are you doing!?"
"I... I don't have that much money!"
Uchiha Yoru's weak words were a plea of having no money, but the hint of resolve in his eyes let Tsunade know.
The kid had not given up on dying on the battlefield.
Tsunade felt a headache coming on. It seemed that she was the reason this kid had ended up like this.
"Kid, you want to die!"
Tsunade's cold voice echoed, and Uchiha Yoru fell silent, not answering.
Seeing Uchiha Yoru's appearance, Tsunade was speechless. The obsessive Uchiha were giving her a massive headache.
Her own brother's death had stimulated an outsider to awaken their eyes, and now she had to find a way to prevent this kid from killing himself.
A ninja might lie, but the Sharingan of the Uchiha clan doesn't.
"Nawaki's matter ends here. I need you to continue to stay in the Uchiha clan."
Under Tsunade's cold voice, a light appeared in Uchiha Yoru's deadened eyes. He slowly looked up at Tsunade, his eyes filled with a look of hope, and he said hoarsely:
"Captain Tsunade, are you saying you want me to investigate the Uchiha clan for traitors?"
A pair of blood-red one-tomoe Sharingan stared intently at her. Only when you faced them personally could you truly know how absurdly obsessive the Uchiha were.
Tsunade was speechless. This kid had really gone over the top, but!
This seemed to be perfect. She could install a pair of eyes in the Uchiha clan, at the very least to know everything that was going on.
Seeing Tsunade not speak, Uchiha Yoru seemed to have imagined something. A look of obsessive determination appeared on his face.
"For Konoha! Captain Tsunade, don't worry. I won't allow anyone to betray the village!"
"Oh, for heaven's sake!"
At that moment, Tsunade sighed in her heart. She finally understood the Uchiha that her clan records spoke of.
The obsessive Uchiha!
As Uchiha Yoru's expression became resolute, he looked at the IV drip on the side and secretly breathed a sigh of relief.
He had finally found a strong backer. This genetic stabilizer was too precious. Fortunately, everything had gone smoothly.
As long as he had Tsunade, he was confident that he could fully fuse with this bloodline in the next five or six years.
"Lie down. Now I'm going to properly research your other bloodline."
Under Tsunade's cold voice, she seemed to acknowledge his plan to be a spy.
Uchiha Yoru remained silent and lay on the bed, but in his heart, he was secretly relieved.
He had won this gamble.
He had not only won over Tsunade as a powerful ally, but he had also awakened his Sharingan.
Sure enough, his own talent wasn't bad. He also had the potential to awaken his eyes, and he had done so at the critical emotional breaking point of the cursed seal.
Even if he had lost the gamble, he still had Mikoto as a fallback.
"Kid, this bloodline has a lot of rejection. Be careful not to use it recklessly, or you might not live for more than a few years."
Tsunade, who was examining Uchiha Yoru's body with a frown, said calmly. Uchiha Yoru, however, remained silent, as if he was still immersed in the matter of Nawaki's death.
This made Tsunade's head ache. It was simply impossible to reason with an Uchiha.
"This unknown bloodline is dormant within you, but because of the rejection effect, your body's self-protection mechanism caused it to form a cursed seal pattern on your neck..."
Tsunade changed the subject and began talking about Uchiha Yoru's unknown new bloodline. As she spoke about it, a look of exploratory desire appeared deep in her eyes.
Bloodline research!
It had never stopped in the ninja world. As the most powerful medical ninja in the world, it was impossible for Tsunade not to be tempted when she finally came across an unknown research subject.
