As an Uchiha I became the Jinchuriki of Senju Tobirama

"I'm sorry, Rin, I can't fully control the water blades yet. I might have caused some damage to your skin."

"I'm very interested in medical ninjutsu, let me help you treat the wound, after all, it was caused by me."

"Hey, Kazuki-kun, are you also interested in medical ninjutsu?" Nohara Rin's eyes lit up, frowned slightly, felt the medical ninjutsu on Kazuki's fingertips, and sighed softly. "How amazing, you are so impressive, Kazuki-kun!"

Kazuki smiled helplessly. "I'm four years older than you, Rin, I've just practiced more than you."

"I believe that you will become a much better medical-nin than me in the future. If you are interested, you are welcome to visit my house. I have some experience in chakra control, thanks to the classics left by my grandfather, which may be helpful to you."

"Wow, really? Kazuki-kun, thank you so much!" Nohara Rin said excitedly. As a child from a civilian family, what she lacked most was this precious knowledge.

"Ahem... Kazuki-kun, are you ready to meet the next opponent?" Ikkaku coughed and became serious. Although he also enjoyed watching this scene full of youthful atmosphere, the competition still had to continue.

The scene of the fight between Kazuki and Rin had made the middle-aged veteran, with a nostalgic smile, recall his youth.

As for the rest of the classmates, most of the boys had a complicated admiration in their eyes, and the girls were somewhat envious.

What kind of luck is this?

Nohara Rin seemed to have lost, but she won back a book of chakra control, and it seems that there may be more...

For example, a love story about a low-key genius from a noble family?

Kakashi looked at Kazuki with a complicated expression, then slowly withdrew the short knife on Obito's neck and warned: "Don't let it happen again. As a ninja, discipline is always the most important thing."

Obito panted, seemingly not paying attention to Kakashi's words.

At that moment, Rin returned with a blushing face, and fixed her gaze on Kazuki without taking her eyes off, even forgetting to greet Kakashi and Obito beside her.

"Rin, are you okay? That guy is damned!" Obito suppressed the emotions that seemed about to explode, forced an awkward smile and tried to comfort Rin.

"Don't talk nonsense, Obito, Kazuki-kun is a gentle and powerful person..." Rin glared at Obito with some dissatisfaction and said in a stern tone.

Obito's breathing became more and more rapid, and his eyes turned a deep red, the black tomoe spinning violently in his eyes.

At the same time, a cold reminder sound also rang in Kazuki's mind.

[Uchiha Obito is detected experiencing strong emotions of jealousy and anger towards the host. The target is bound!]

Jealousy, anger...

Kazuki pondered these two words, turned to look at Obito, and laughed silently.

The anger was understandable.

After all, the object of secret love is controlled by others. Rin even scolded him for Kazuki, and he was dissatisfied and angry.

But jealousy is very intriguing.

What are you jealous of, Obito?

Are you jealous that you can't hug Rin, or do you want to touch her neck like me, see the blush on her face up close, and control her emotions?

Kazuki has a bad impression of Obito.

Certainly, Obito might seem like a bright and cheerful boy now, but he was someone who could not be trusted.

In the original timeline, Minato may not have cared for him especially, but Kushina really looked after him like a younger brother. Cheering him up when he was down, making him lunch boxes, and telling him to protect himself before going into battle...

But despite Kushina's care for him, Obito was the one who cruelly attacked on the day Kushina gave birth, resulting in her and Minato's deaths, and even attempted to attack Naruto.

His former teacher was ruined by him in one night, and it also brought Naruto a gray childhood.

And all this cannot be simply attributed to the death of Nohara Rin.

Without Nohara Rin, there would be Yamanaka Rin and Hatake Rin...

In this tragic shinobi world, most people will have unsatisfactory things happen. With Uchiha Madara eyeing him, Uchiha Obito's fate is almost doomed.

Should he take the trouble to try to get close to a vicious dog that he can't tame...

Or should he treat him as a leek from the beginning?

Kazuki has made a choice.

Perhaps, Uchiha Obito is the kind of Uchiha that Senju Tobirama fears. He has so-called love in his heart, but he cannot control the power brought by emotions. He destroys everything in the name of love and becomes a madman without reason and logic...

Listening to Rin's scolding, Obito covered his eyes and trembled.

After a moment, he pulled his hands away, revealing a pair of two-tomoe Sharingan, glowing with a strange, red glow.

"Hahahahahahahahahaha!"

Obito felt the power coming from his eyes and laughed loudly. His emotions seemed to rise along with the surging pupil power, and he could not restrain himself.

"Rin, I'm really a genius!"

Obito pushed Kakashi away, took a few steps forward, pointed at Kazuki, and shouted: "You bastard, you dare to do that to Rin, wait for me!"

"Hmm, I'll tell you that the real genius is the Uchiha who has awakened the Sharingan." The two tomoe in Obito's eyes slowly rotated.

Except for Kazuki, no one present expected Uchiha Obito, who was always jumping, to open the Sharingan in such a dramatic manner.

Shisui clenched his fists, eyes narrowing in a dangerous glare as he watched Obito yell at Kazuki. He bit his lip hard. "If it weren't for my brother not letting me reveal the Sharingan… what if you, the last place, have awakened the two-tomoe Sharingan?"

After Obito's performance, the place fell deathly silent for a few moments before erupting into commotion.

"That's the Sharingan... If I'm not mistaken, it's two tomoe!" Kurenai said, staring into Obito's eyes, biting her lips and clenching her fists in frustration.

Kurenai had trained hard in genjutsu to improve her skills.

But the cruel reality was, in the shinobi world, any genjutsu is ridiculous in front of the Uchiha clan's Sharingan.

Obito's ridiculous way of awakening the Sharingan made Kurenai feel disillusioned with the training.

Is the effort… really worth anything?

Seeing the object of his secret love being embraced, can he directly obtain at least the combat power of a Chunin?

Kurenai's shock and frustration was shared by others.

Beside her, Asuma also frowned, feeling the terror of the Uchiha clan for the first time.

Ordinary students didn't think about it that deeply.

"Wow… Obito who used to only do nonsense, has actually awakened the Uchiha clan's kekkei genkai!"

"Is he really a genius? It's incredible. The Uchiha clan really has hidden talents..."

"Now Uchiha Kazuki is in trouble. It's obvious that Uchiha Obito likes Nohara Rin. My father said that if it's an adult Uchiha, he can easily kill a Chunin with these eyes!"

"Yes, although they may not face each other now, but they are both part of the same clan…"

Obito immersed himself in the amazement and admiration of everyone, he closed his eyes for a moment and enjoyed the taste of being a genius and possessing power.

After a while, he opened his eyes and first gave Kazuki a warning glance. Then, he quickly turned to Rin, showing her a smile that he thought was the most attractive. "Rin, don't worry, I will protect you from now on, no one will be able to hurt you!"

At that moment, Obito's eyes were shining with a red glow, and his expression was slightly distorted with emotion.

"Perfect… I like your expression." The tomoe on Kazuki's Sharingan slowly rotated, connecting with the residual ocular power in Rin's body.

Rin looked at Obito who was expressing his love to him, and inexplicably felt a little uncomfortable in his heart. Under the influence of Kazuki's pupil power, this emotion swelled and evolved into fear...

Then, Rin had hallucinations. She saw Uchiha Obito holding a thick iron chain and tying her to the wall. Half of Obito's face was fierce and the other half was gentle. He then asked her in a deep voice: "Rin, why do you want to talk to Uchiha Kazuki! Why do you want to talk to Hatake Kakashi! Why do you want to talk to strangers!!"

Rin's eyes filled with fear, and she suddenly took a step back, a horrified expression on her face.

The smile on Obito's face froze.

Rin's small step back, though not very big, caused a sharp pain in his heart.

"Are you serious about taking a half step back? A small action hurts so much~" Kazuki listened to the electronic sound and hummed softly in a good mood.

[From the target Uchiha Obito, you gain the Uchiha clan bloodline enhancement!]

The ocular power in Kazuki's eyes and the chakra in his body began to increase.

"With the improvement of my Uchiha bloodline and the combination with the incomplete Sage Body that I possess, my chakra level is quite high, even among the Jonin."

"My body has also become stronger."

Kazuki moved his body full of strength but frowned. He was not particularly satisfied with the reward this time...

From Shisui, Kazuki realized that the system's mechanism was quite strict. The rewards obtained by stimulating the targets depended on both the target's talent and their strength at the time.

But Obito was different of Shisui…

In Kazuki's eyes, Obito was a treasure trove. Although he was only less than eight years old and could not compare to Tobirama, he should at least have more potential.
