Chapter 183: The Energy of the World
The dark blue chakra was incredibly pure.
Inside Ryosuke's body, it flowed smoothly through his meridians like an obedient kitten. As his consciousness guided it, the senjutsu chakra no longer surged uncontrollably as it had half an hour ago.
Out of control?
Of course not. Since Ryosuke had chosen to try it, he had already considered multiple possibilities.
He was analyzing the senjutsu chakra, attempting to grasp the essence of natural energy. What Ryosuke wanted was to experiment with refining natural energy directly.
Starting from scratch was always difficult—especially when it involved tremendous risks and no margin for error.
But what if...
What if Ryosuke had already obtained the end result from the beginning, and then used that outcome to reverse-engineer the necessary steps and requirements? That would make everything far easier and significantly reduce the risks.
However, one crucial prerequisite remained: Ryosuke had to fully control this senjutsu chakra that did not originate from him.
That was the first hurdle.
And since he had allowed Naruto to inject this chakra into him, Ryosuke naturally had multiple strategies prepared to manage it.
Initially, after experiencing the wild power of the senjutsu chakra, he thought it would take a long time to suppress and master it.
But the result—
It went too smoothly.
So smoothly, in fact, that Ryosuke found it hard to believe.
Could just a trace of senjutsu chakra really give him such a massive edge over ordinary shinobi that it resembled the chakra levels of a Jinchūriki?
This was Ryosuke's first attempt. He had planned to use the power of his Byakugan along with his naturally vast chakra reserves to suppress and control the foreign energy.
But then something unexpected happened.
When the senjutsu chakra gathered near his temple under his guidance, drawn by the power of his Byakugan, it became surprisingly obedient.
He didn't even need to control it anymore. It flowed naturally into his Byakugan—though it wasn't converted into pupil power.
At that moment, Ryosuke seemed to grasp something instinctively, completing the transformation through his Byakugan without even realizing it.
The entire process was seamless. When the senjutsu chakra was fully absorbed and became a part of him, flowing freely through his meridians, Ryosuke was momentarily stunned.
Naruto's consciousness, once embedded in that chakra, had completely vanished—replaced by Ryosuke's own.
He could communicate with this high-level energy easily, guide it, and even... use it.
Because he found no precedent for this in his mental database, Ryosuke relied solely on his personal research into chakra to judge the situation.
—Maybe... he had unknowingly tapped into an ability belonging to the Tenseigan.
Looking back, the best method for handling uncontrollable senjutsu chakra was clearly to absorb and internalize it.
Throughout the ninja world's history, many techniques allowed the user to absorb the chakra of others and use it for their own benefit. Even minor hidden villages possessed versions of such techniques.
The weaker ones were found in places like the Hidden Sound Village or used by wandering ninjas. Stronger techniques included high-tier bloodline limits such as Wood Release and the Rinnegan.
The key differences among these techniques lay in complexity and success rate. The more sophisticated the method, the more chakra it could absorb—and the less chance of backlash.
Likewise, advanced absorption techniques boasted better conversion efficiency, transforming more of the absorbed chakra into usable energy.
Yet, Ryosuke had never heard of anyone absorbing senjutsu chakra before.
"I have a feeling... I could extract the chakra from Naruto just by lifting my hand."
Even while meditating with his eyes closed, the Byakugan's insight allowed him to clearly observe the surrounding environment.
Since the senjutsu chakra within him had stabilized, he no longer needed to focus all his attention on his own body.
As for the aftermath of what had just occurred, Ryosuke suspected he had stumbled upon an ability akin to those of the Tenseigan.
Within his field of vision, the chakra inside Naruto was fully exposed—nothing hidden, nothing blocked.
This level of chakra perception was something he already possessed.
But now, alongside that insight came a new sensation—a certainty: if he activated his pupil power, he could draw chakra from Naruto across an invisible distance.
No, it wasn't just a feeling. He could actually do it.
The ability to absorb chakra remotely seemed innate. Perhaps this was the power he had been waiting for—the chakra absorption of the Tenseigan.
Although he hadn't yet awakened the Tenseigan itself, he had undeniably gained one of its signature abilities.
Faced with this revelation, Ryosuke felt a complex mix of emotions—shock, awe, even a touch of discomfort.
Since arriving in this world with this bloodline, this was the first time he had gained an inherited ability so easily.
Yes, it had triggered passively. But for the first time, he experienced that sensation... the thrill of power awakening from his bloodline.
Maybe this was why the Uchiha were so fearsome. Each evolution of the Sharingan activated another dormant ability, enhancing physical prowess and perception in one seamless flow.
In contrast, the Hyuga bloodline seemed weaker—and was even degrading over time.
"Now that I've gained this new ability, I should focus on what matters most..."
Temporarily setting Naruto aside, Ryosuke turned his attention back to the trace of senjutsu chakra flowing gently through his meridians.
A thought emerged in his mind.
Within the spiderweb-like mesh of meridians, the chakra of senjutsu shimmered like deep blue seawater under a clear sky.
It flowed steadily with his consciousness, finally settling at his abdomen.
Dots of chakra floated like stars. Against the dark canvas of his abdomen, they resembled a painting of the starry sea.
The higher-concentrated, darker energy entering this pool no longer provoked unrest. The rest of the chakra had already acknowledged this elevated form as part of the body.
They accepted it.
So now came the second phase.
Ryosuke didn't plan to rest.
The first phase had gone smoothly—almost too smoothly—and Ryosuke could only hope the second phase would follow suit.
With a faint tremor, the high-level energy substance in his abdomen began to shift. Ryosuke focused his mind, attempting to analyze the fusion process in real time. His mental faculties were pushed to the limit as he observed the ever-changing strand of sage chakra.
The Byakugan, fully activated, shone with clarity. Both its Insight and X-ray capabilities worked in tandem, dissecting every detail of the chakra's transformation. Ryosuke was determined not to miss even the slightest change—any oversight could compromise the next stage of progress.
Within the deep blue chakra—dense and viscous like paint—a sliver of pale blue energy separated itself.
This... was physical energy.
Next came the spiritual energy.
Ryosuke was like a researcher conducting delicate experiments beneath a microscope—his heart pounding with excitement, yet his thoughts razor-sharp, maintaining calm amid the storm.
Under his careful guidance, the chakra—though borrowed at first—had already been refined into a substance uniquely his. Now, it was being extracted and decomposed into three distinct energy forms.
Physical and spiritual energies were clear and familiar. Ryosuke had long grown used to sensing and manipulating these forces. But natural energy... was different.
This energy floated free—subtle, elusive. It flowed through the deep sea, shimmered in the starry sky, and pulsed quietly within Ryosuke's body. Yet unlike the other energies, it remained unseen—he could only perceive it with his mind.
And that... was enough.
Compared to the chaotic surges he'd witnessed outside—like those during Naruto's wild training—what flowed within him now was calmer, more obedient. He could feel it. Control it. Remember it.
…
Time passed.
Outside, Naruto grew increasingly anxious.
Inside, Ryosuke sat frozen in focus—no longer calm, but hesitant, unsure. He'd lost track of the hours.
Still, in less than a day, he had memorized every sensation this energy produced. His body, mind, and spirit were now fully aware of its presence. With his analytical thinking, he'd understood the nature of natural energy the very moment he'd first separated it.
He could even faintly sense it flowing through the air around him.
Still, Ryosuke remained cautious. He continued meditating for several more hours—refining his perceptions, honing his awareness. The more he felt, the more overwhelmed he became. His understanding deepened, but so too did the realization of his own insignificance.
For the deeper his awareness of natural energy grew, the more he began to sense its presence everywhere.
Natural energy… the planet's gift. A high-level force that existed in air, sky, land, water, trees, dew, grass—everything lacking conscious thought possessed it.
Before, Ryosuke had been blind to its presence.
Now, he couldn't ignore it.
Like a diver sinking into the depths of the ocean, Ryosuke sat cross-legged atop Hokage Rock, fully immersed in the flow of natural energy. He could feel its contradictory nature—its corrosion, its tolerance, its rejection—laid bare in his perception.
And it scared him.
…
"I think I understand."
When he opened his eyes, the sky was already tinted with dusk.
He and Naruto had spent the entire day behind the mountain without so much as eating.
But when Ryosuke looked up, the telltale patterns of Sage Mode did not appear near his eyes.
"…Huh?"
Beside him, acting as a vigilant protector, Naruto blinked in confusion. Then his eyes widened, and he blurted, "Eh?!"
"Ryosuke… don't tell me you've already mastered Sage Mode?!"
His tone was laced with disbelief.
He knew Ryosuke was strong, sure—but this? This was absurd. Sage Mode training wasn't supposed to be easy. Had he really spent the whole afternoon worrying for nothing?
"…Maybe," Ryosuke replied, turning toward him with a small, almost apologetic smile. "But I think a proper attempt still needs a bit of preparation."
His answer was deliberately vague.
It wasn't incorrect to say he'd figured out how to enter Sage Mode. But understanding something wasn't the same as being able to do it. He wasn't sure if he could truly gather natural energy, refine sage chakra, and enter the state completely.
"This isn't something you can achieve through perception and analysis alone," Ryosuke admitted, raising his arm. "Real practice requires much more…"
As he spoke, he noticed how the natural energy around him actively avoided his outstretched palm. There was something like an invisible film between them—two forces occupying different dimensions.
His training plan had been divided into three stages.
The first: transforming and controlling sage chakra.
He'd completed that in record time.
The second: sensing and recognizing natural energy.
That took longer and drained more effort—but it, too, had been accomplished.
Now came the final and most dangerous phase—absorbing natural energy and condensing sage chakra based on the fusion laws he had deciphered.
This was the true challenge.
At first, Ryosuke had been confident—too confident. He'd even thought he might complete Sage Mode in a single attempt.
Now, he knew better.
Ryosuke had never been one to indulge in baseless arrogance. His confidence always stemmed from logic and ability.
He likened himself to a diver clad in a protective suit. Within the ocean depths, the suit shielded him from the crushing waters. As long as the seal held, he remained safe.
But what if he unzipped the suit? What if he let even a sip of ocean water in?
Then everything might spiral out of control.
Faced with this endless "ocean" of energy, Ryosuke wasn't sure if he could handle what rushed in.
Without that "diving suit" of chakra control, the repulsion he'd sensed from the natural energy could turn into raw corrosion, flooding his body in an instant.
He needed more time.
More familiarity.
More preparation.
Only then could he attempt true mastery of Sage Mode.
