"Hehe, thanks, Dad!"
Ren Takashi grinned as he expressed his gratitude.
He planned to use the clan's existing sealing techniques as a foundation. Once he became Tsunade's disciple, he could then acquire more advanced sealing arts from her or even from Uzumaki Mito herself.
His goal was to develop a safe and reliable method to refine and control the chakra seed.
Only after achieving that could he pass on the Chakra Circulation Method to his family—enhancing their strength and even offering them a path toward longevity.
Yes, Ren's hopes for the Chakra Circulation Method extended that far.
Once a shinobi mastered it and connected with the Heavens and Earth, drawing in natural energy and refining it into their own, their body and life essence would undergo a fundamental transformation. Their lifespan would increase, and they'd step into true transcendence.
"Oh, right! Dad, Mom—this is the chakra refining technique I improved. Take a look!"
"If it suits you, I recommend switching to it."
"Based on my tests, its refining efficiency is three times higher than our Uchiha version, and it boosts energy conversion by 20%."
"In other words, using this method lets you synthesize 20% more chakra with the same effort."
After breakfast, Ren pulled out a scroll and handed it to his father.
This was the simplified version of his Perfect Chakra Refining Method.
While not as powerful, it was much easier to learn and still superior to the clan's traditional technique.
As for the full version? Ren doubted even his parents—or most ninja in the world—could manage it.
"What?"
Uchiha Nobuhiko and Uchiha Kokomi were both stunned. As they unrolled the scroll, their disbelief was written all over their faces.
"You're serious? It's really that effective?"
Ren just shrugged with a smile. "Try it yourselves. Shouldn't be hard for you two."
"Alright, let's test it!"
Neither could sit still. They carefully memorized and analyzed the new method—thanks to their extensive experience and high-level chakra control, it didn't take long.
Both of them sat down in lotus position and began refining chakra using Ren's method.
Before that, Nobuhiko checked their privacy seals and cast an extra one over the dining room.
Ten minutes later…
They both opened their eyes—shock written across their faces.
"It's real! Damn!"
The results didn't lie. The refining speed and chakra quality clearly surpassed their old method.
"You haven't told anyone else about this, have you?" Nobuhiko asked with concern.
"Of course not," Ren replied, shaking his head. "Do I look that reckless to you?"
"That's good."
The couple exchanged a relieved look.
"This is too dangerous to expose. If people find out you created something like this, you'll be a walking target," Nobuhiko warned sternly.
"You mustn't tell anyone—especially not your brother."
"Not until we've unified the clan, reformed the Police Force, and rooted out the spies and turncoats."
"Until then, you need to focus on strengthening yourself without harming your body. Only when you're strong enough can we stop worrying about your safety."
Ren nodded seriously. "I understand."
"Give me a few years. That day won't be far off."
"But for now, you two should continue training with this method."
"Once you've mastered it, I'll have an even bigger surprise for you," he added with a grin.
He estimated it would take his parents at least half a year to fully master the new technique.
By then, he would have become Tsunade's disciple, learned advanced sealing techniques, and completed his safe chakra seed refinement method.
At that point, they could finally begin practicing the Chakra Circulation Method.
"Oh?"
Nobuhiko and Kokomi both raised their brows. They could tell their son was holding something big back. But they didn't press him.
He was becoming more mysterious by the day. Let him be.
Over the next 18 days, Ren split his time between refining chakra, cultivating the Chakra Circulation Method and Perfect Sharingan Awakening Method, and diving into sealing techniques.
He continued his medical ninjutsu training openly, drawing intentional attention.
With Uchiha Nobuhiko fanning the flames behind the scenes, word soon spread: Ren Takashi, at just five years old, had already mastered the Mystical Palm Technique in a single day.
It didn't take long for the Third Hokage, Danzo, and several clan elders in Konoha to take notice.
Nobuhiko was said to have raged during a clan meeting, calling out traitors and leaks within the Uchiha.
In the Hokage's office...
Sarutobi Hiruzen smoked his pipe and frowned as he read the latest intel from the ANBU.
"A five-year-old mastering the Mystical Palm Technique in a single day, and excelling in other medical jutsu too?"
"A true genius…"
"And yet another one born into the Uchiha… and of all people, the son of Nobuhiko."
He'd thought Fugaku was exceptional—but this Ren Takashi clearly surpassed his older brother in potential.
Hiruzen knew better than to believe this was limited to medical ninjutsu.
To learn the Mystical Palm Technique, one needed not only extreme chakra control but also a deep understanding of Yang Release.
In other words, this child was also bound to be a formidable ninjutsu prodigy.
A flicker of appreciation and wariness lit up in Hiruzen's mind.
"The Uchiha cannot be allowed to grow unchecked."
"But the Academy term starts in a few days…"
"He'll be enrolling. That will be our chance to observe him."
"He's still young—his worldview isn't fully formed. He might be moldable…"
"If I can win him over and use him as a planted seed within the Uchiha, he could become a powerful tool in our hands…"
"And with his status as the clan head's son, the influence he'd wield could shape the Uchiha from the inside out."
As this thought surfaced, so did an image of Tsunade in Hiruzen's mind.
