"I wish to know the best way to become Tsunade's disciple."
[Wish granted. Consume 20 wish points to initiate the optimal path to becoming Tsunade's student. The user should self-study medical ninjutsu and chakra-related scrolls within the Uchiha clan, gradually build a reputation as a prodigy in medical ninjutsu, and display deep recognition of the Will of Fire. Then wait for the right timing.]
"Twenty wish points? Not bad."
Without hesitation, Ren Takashi made the wish.
"I wish to consume 20 wish points and activate the best sequence for becoming Tsunade's student."
In that moment, a streak of ethereal light, invisible to the naked eye, erupted from his body and vanished into the skies over Konoha.
Destiny's threads began to subtly shift due to the miraculous force of the wish—and that shift would only grow.
Ten Days Later
"Whew… Finally completed the energy circuit construction in every single cell."
"At my current level of chakra control and physical development, I'll be ready to switch to the Chakra Circulation Method in just two days."
Ren exhaled deeply, a rare look of satisfaction on his face. He could feel his body responding with a newfound smoothness and clarity.
His mastery of the Perfect Chakra Refinement Technique had reached its peak. Every cell in his body now possessed a complete energy channel. Not only did this boost his refinement efficiency, but his overall chakra quantity had increased significantly—by his estimation, it was already at the level of an average Chūnin.
Terrifying, really. But considering his full-body refinement, enhanced chakra extraction efficiency, and top-tier physical constitution, it made sense.
His parents, especially Uchiha Nobuhiko, were utterly shocked.
Consequently, his father was already preparing to formally teach him ninjutsu.
His internal martial arts training had also progressed at lightning speed. With his high-level comprehension and a refined medicinal bath formula, his physique had strengthened by more than 50% in just ten days—bringing him one step away from reaching the next stage: Bright Strength.
More importantly, he noticed something crucial: while physical training improved cellular toughness, it didn't significantly boost life force.
True chakra quantity was tied more to vitality than brute strength—just look at Might Guy, whose chakra remained limited despite overwhelming physical power. Conversely, the Uzumaki clan possessed massive chakra reserves due to their exceptional life force.
Fortunately for Ren, his inner martial arts system directly enhanced life force and vitality. The more he advanced, the more profound this effect would become.
"That means… injuries and long-term internal damage, even those caused by excessive chakra use—like my father's—might be treatable through internal martial arts."
"If he continues, he could extend both his peak period and lifespan."
"And once I've finalized the adaptations for shinobi physiology, I can teach this to my mother… and even my brother."
Ren smirked. Though Fugaku wasn't the brightest, he was still blood. If properly cultivated, he could become a valuable ally and tool.
"As for Mikoto… once our relationship deepens a bit more, I'll decide."
Two Days Later – Ren's Room
Seated cross-legged, eyes closed, Ren began circulating chakra through his meridians using the Chakra Circulation Method for the first time. Slowly and steadily, he guided the chakra along the prescribed route.
It took him half an hour to complete a single great circulation—guiding chakra through all his meridians to converge at the middle dantian, located near his solar plexus.
With a final push, he broke open a key acupuncture node: the Shanzhong point.
Instead of scattering, the chakra began pooling and expanding the newly formed chakra core—his dantian.
When all of his current chakra had been drawn into this core, the dantian stabilized and stopped expanding. But Ren knew this was only the beginning. Over time, as more chakra was gathered and refined, it would continue to grow and strengthen.
"Finally… it's done!"
"With this, I can begin accumulating and refining chakra long-term."
He felt the shift deeply. His entire system was transforming from momentary bursts to long-term cultivation.
But just as he prepared to end the session, his spiritual sense picked up something strange in the very center of his chakra core—a foreign presence.
"Huh? What is that?"
Focusing his senses, Ren zeroed in on it. At the heart of his chakra vortex, a seed-like structure had taken root.
It pulsed with energy, subtly drawing in chakra and seemingly aiding in synthesis and refinement.
"A chakra seed…?"
"Could this be the original form of the chakra bestowed upon the shinobi world by the Sage of Six Paths?"
"Is this the true reason why people in this world can merge mental and physical energy to create chakra so easily?"
His mind reeled. In his past life, Ren had tried many times to harness internal energy systems—whether chakra, ki, or magic—but had failed again and again.
Clearly, the presence of this chakra seed was the deciding factor. Without it, combining mind and body energy into chakra was practically impossible.
But with it…
Everything became possible.
