Chapter 3: Kazuki's Power and Shisui's Growth

What was Tobirama looking at? This evil Uchiha brat had not only learned his simplified Water Release, but had also used the genjutsu he had carefully improved to deal with the Uchiha clan?

This feeling, this feeling...

It made Tobirama feel very absurd, especially when the Bringer-of-Darkness Technique released by Kazuki was so perfect.

It was like, it was like he was there in person...

If Tobirama hadn't made it clear that he was a virgin, he would have suspected that he had had some romantic past with a girl from the Uchiha clan!

[From the target Senju Tobirama: You get the Kunai Throwing Technique (Senju Tobirama version)]

The sound of gold coins exploding rang in Kazuki's mind.

At this moment, Shisui recalled the knowledge he had learned from the Ninja School to the Clan School, and his eyes widened suddenly!

Tobirama had studied the Uchiha clan thoroughly. For their part, the Uchiha clan had also completely stripped Tobirama bare.

"Bringer-of-Darkness Technique..." Shisui muttered to himself in the darkness: "How much power are you hiding, brother?"

Thinking of what he said about using all his strength, Shisui suddenly felt extremely ashamed.

While he was still thinking about working hard to be promoted to chunin as a shining genius, Kazuki, who had always been unknown, had already reached the level of jonin.

The feeling of having shown off to his brother and then being educated by him was extremely uncomfortable for Shisui, even more so than when Kazuki caught him wetting the bed at four years old.

The arrogance of a genius, the shame before Kazuki, the bitterness of the reversal of strength between brothers...

A variety of complex emotions stimulated Shisui.

In his left eye, the single tomoe began to spin rapidly, and his eye power increased dramatically, turning into two tomoe.

Shisui felt the increase in his chakra as well as the increase in ocular power that the double tomoe gave him and couldn't help but laugh out loud. "Hahahahaha! Brother, I am still stronger!"

[Uchiha Shisui is detected to have a strong intention to defeat the host. Target bound!]

Kazuki, hearing the system notification and sensing the change in Shisui's chakra, was somewhat surprised and now understood the Uchiha clan a little better.

Breaking boundaries in the middle of battle...

This extremely unreasonable behavior seems so reasonable to the Uchiha.

Shisui's maniacal laughter also demonstrated the great emotional impact of the Sharingan's evolution.

What surprised Kazuki the most was Shisui's deep obsession with defeating him, to the point that the system bound him as its target!

"In that case, brother, I won't be so kind..."

Kazuki mobilized all of his chakra. Although the Sage Body was incomplete, it still provided him with an impressive amount of chakra.

At least, more than the middle-aged Kakashi...

As Shisui laughed he broke the darkness in front of him.

His excited smile was still on his face, but when the darkness dissipated, Shisui's smile froze...

The training camp had turned into an ocean.

Kazuki stood on top of a huge water dragon, looking down at it with a smile on his face.

At that moment, the surging waves covered the ground beneath Shisui's feet, submerging him up to his hips.

Beneath the water dragon, a whirlwind that appeared out of nowhere exerted a strong attraction, forcing Shisui to concentrate his chakra on his feet to maintain balance.

Under the observation of Shisui's Sharingan, he noticed that the water dragon was composed of countless sharp water blades!

If that hit him, he would probably turn into minced meat…

What's even more weird is that Kazuki stood on the water dragon safely.

Tobirama's face was already stiff. Although others might not know what technique this was, he was more than familiar with it.

"Where did this bastard boy learn my technique from!"

But after a moment, Tobirama's thoughts gradually calmed down.

From being sealed at first to being surprised now, Tobirama adjusted his mindset and had expectations and acceptance of Kazuki's strange talent very similar to his own.

Shisui swallowed hard and observed the flow of Kazuki's chakra. "This level of chakra…"

Shisui looked up with effort, looking at Kazuki who was standing with his arms crossed on top of the water dragon.

In their minds, the scolding voices of the Uchiha clan school elders echoed inexplicably.

"Hmph, today's history class should talk about Senju Tobirama..."

"This man is despicable and insidious. He will do anything to win, and his moral level is extremely low!"

"But..."

"He is certainly an extremely difficult opponent. With just the Water Release and Genjutsu, he can subdue all the Uchiha with three tomoe… Since he developed the Flying Thunder God Technique, not even Izuna-sama could defeat him…"

"Sigh, Senju Tobirama!"

Kazuki's appearance blurred before Shisui's eyes and was about to overlap with Senju Tobirama's.

Shisui was stunned, staring blankly at Kazuki.

Kazuki slowly deactivated the technique, then approached Shisui and while smiling he caressed his wet head. "The Water Release: Water Dragon Biting Explosion is a very complicated technique, even for me, using it is a bit difficult…"

Hearing Kazuki's strange and humble words, Shisui just wanted to complain.

[From the target Uchiha Shisui, you get the talent of genjutsu (Shisui version)!]

Hearing this electronic sound, Kazuki was slightly stunned.

Just a genjutsu talent?

But then, remembering that the system's rewards are directly related to the target's level, Kazuki calmed down.

At almost six years old, even with exceptional talent, Shisui's abilities were still limited.

Kazuki didn't pay much attention to the reward, and with a gentle gaze, he took Shisui's hand with an apologetic expression.

"I'm sorry, Shisui, I haven't cared about you much lately..."

"From now on, this won't happen again."

Shisui felt the familiar temperature in his palm, and his heart warmed, but he still said in confusion: "Why do you say that, brother..."

Kazuki cared about him a lot, and Shisui always felt that he was the happiest brother in the Uchiha clan.

"You have awakened the Sharingan, Shisui."

Kazuki sighed deeply, looking at Shisui's Sharingan, and said in a deep voice: "Awakening the Sharingan requires strong emotional stimulation…"

"You are a child of almost six years old. With your temperament, and without experiencing any unfortunate accidents, nor the war..."

"So, where does your emotional stimulation come from?"

Kazuki squeezed Shisui's hand and said regretfully: "It can only be due to the tensions between the village and the clan. Although you have impressive talent, such a responsibility is something you should not bear."

"And I, as your brother, did not realize it in time and allowed my dear brother to suffer from this pressure to the point of awakening the Sharingan."

Kazuki frowned and let out a bitter smile. "Shisui, do you think I am a very incompetent brother? "

Shisui shook his head quickly, but Kazuki didn't give him a chance to respond and continued: "But it won't be like that in the future, Shisui."

"Since you care as much about the matter of the clan and the village as your brother, I have to take on that responsibility."

"I won't make the same mistake again. This time, forgive me, Shisui."

Kazuki touched Shisui's forehead, looking into his eyes seriously.

Shisui's eyes were already filled with tears, which welled up the moment Kazuki apologized.

[From target Uchiha Shisui, you gain a reward: Sharingan - Two Tomoe!]

[From target Uchiha Shisui, you gain the special talent: Uchiha Love (Shisui)]

[Uchiha Love (Shisui): Your target Shisui's heart has been captured by your actions. This target's devotion and loyalty cannot be changed by any technique.]

Shisui's emotions seemed to have received a critical blow, with the electronic sounds of rewards resonating continuously.

Seeing the rewards, Kazuki's words of 'regret' almost made Shisui's heart explode.

Kazuki gently wiped away Shisui's tears and said slowly: "Why are you crying? You are not allowed to cry."

"Come on, join me to buy ingredients. I promised to make you a special grilled fish tonight."

Hearing this, Shisui's tears began to well up again, but remembering Kazuki's warning, he held them back again, looking quite comical.

However, Shisui probably didn't realize that, at that moment, Kazuki was lamenting in his mind: 'My brother, it seems that I still need to help you improve your strength…'

'With such touching words, and you only give me a double-tomoe Sharingan as a reward…'

...

Shisui happily enjoyed the special grilled fish prepared by Kazuki.

Although for this little genius of the Uchiha clan it was the first time he experienced the sensation of being defeated without mercy...

His older brother's sincere concern made him forget his pain and immerse himself in the warm embrace of family love, unable to escape from it.

"Little brat." Tobirama's voice sounded beside Kazuki's ear. "I know you can hear me. You and this kid named Shisui are both descendants of Kagami, right..."

Kazuki, while smiling at the sight of Shisui wolfing down the food, replied to Tobirama inside him. "Isn't it true that you, the Hokage who betrayed the Will of Fire, always say that you can identify Uchiha with just one look?"

"So, guess for yourself."

Tobirama narrowed his eyes and gritted his teeth.

Shisui's facial features are cut from the same mold as Uchiha Kagami. However, Kazuki had a noticeably different appearance.
