Time flew by, and soon, it was deep into the night.
As Seimei once again extracted chakra to nurture his Byakugan, the familiar tingling sensation was gone. Instead, he felt a faint swelling.
Immediately, he realized—he had reached his limit.
He stopped the chakra infusion and carefully sensed the chakra within the dimensional space at his forehead. It had decreased by about a million points, which was roughly what he had expected.
With that, he opened his eyes.
"Ha~~~"
Covering his mouth, he yawned, then got up and left the training room.
After a quick wash-up, he returned to his bedroom and went straight to sleep.
The night passed in silence.

At dawn, Seimei had already left his courtyard.
Leaving behind a shadow clone to watch over the house, he followed his usual routine—heading to the food street, enjoying a hearty breakfast, and then blending into the early morning crowd leaving the village.
Once he reached a secluded path with no one around, he activated the Flying Thunder God Technique and instantly disappeared.
His vision shifted dramatically.
In the next moment, he arrived at the island in the southern sea of the Land of Fire—his personal training ground.
Looking around, everything was just as familiar as ever.
The salty sea breeze carried a faint bitterness. Seimei, as usual, cast Wind Release: Wings of Wind, soaring into the sky. Then, he slightly loosened the seal on his forehead, activating his Byakugan to scan the surroundings.
A few minutes later, he had surveyed a ten-kilometer radius and found nothing unusual.
With that confirmed, he descended back onto the island.
Standing atop a massive boulder, he formed a hand seal and performed Multiple Shadow Clone Jutsu, instantly splitting into over a hundred clones.
Following his pre-planned training schedule, Seimei divided them into groups, assigning each one specific skills to practice.
Only after they left did he begin his own training.
Since he had just arrived and his body wasn't fully warmed up, he decided not to start with Lightning Release Chakra Mode right away. Instead, he cast Palm Sage Jutsu, using Yang Release Chakra to stimulate his body's evolution.
However, unlike before—where he simply used Palm Sage Jutsu repeatedly—this time, every five or six cycles, he activated his Mangekyō Sharingan, channeling the power of "Authority of Man" to enhance the technique.
As a result, the efficiency of his physical reinforcement increased once again.
Based on his estimates, his current Palm Sage Jutsu training was at least 1.5 times more efficient than when he first mastered it.
In other words, since his last improvement, his progress had increased by another 20%.
Without a doubt, this would significantly reduce the time needed for his body to reach the next evolutionary threshold.
Still, to determine exactly how long, he would need to conduct further tests in conjunction with Lightning Release Chakra Mode.
Time passed, second by second.
Soon, an hour had gone by.
Following his plan, Seimei dismissed his Multiple Shadow Clones, absorbing all their training experiences and memories, converting them into skill proficiency.
Then, after consuming a few newly acquired enhanced ration pills to replenish his energy, he repeated the process—creating another hundred clones to begin the second round of training.
This time, however, instead of continuing Palm Sage Jutsu, he switched to practicing Lightning Release Chakra Mode.
Removing his equipment and shedding his outer garments, Seimei leaped off the boulder and moved toward a small clearing within the nearby forest.
"Inhale... Exhale..."
Closing his eyes, he took a deep breath, then slowly exhaled.
The next moment, his eyes snapped open.
Focusing his attention, he gathered his chakra, transformed it into Lightning Release Chakra, and activated Lightning Release Chakra Mode.
Crackle—!
Blinding arcs of electricity erupted from his body.
Then, they gradually dimmed.
Finally, the lightning condensed into small serpentine bolts, coiling around his body.
Feeling the electric surges, Seimei believed that even without a dedicated training method, he could use his knowledge to develop a compatible Lightning Release Taijutsu style.
However...
He shook his head.
For now, he didn't need to.
It was better to treat this as a pure body-strengthening technique for the time being.
With that thought, he began moving, allowing the lightning to shrink into even finer currents that burrowed into and out of his skin.
By using this process, he further reinforced his body.
This kind of extreme training was only possible because of chakra—the supernatural energy of the ninja world. In his previous life, attempting this would have led to instant, irreversible damage rather than enhancement.
So yeah—don't try this at home.
Zzzzt—!
Suddenly, a rogue surge of electricity went out of control, leaving a charred black streak on his skin.
"Ugh—"
A sharp, burning pain shot through him. Seimei grunted and quickly refocused, no longer letting his mind wander. He concentrated all his effort on precisely controlling the lightning, ensuring it followed the proper flow.
Still, despite his best efforts, occasional sparks would escape, leaving more burn marks across his body.
There was no helping it—his Lightning Release Chakra Mode proficiency was still too low. And since he was using an excessive amount of chakra for enhancement, occasional slip-ups were inevitable.
But Seimei wasn't afraid of injuries. With 24 points in Constitution and the Hashirama Cells granting him unparalleled regeneration, these minor wounds were insignificant.
In fact, this process of injury followed by rapid healing actually accelerated his body's reinforcement.
Thus, amid repeated bursts of rogue electricity, another hour slipped away.
Halting his Lightning Release Chakra Mode, Seimei gathered his chakra, activating his body's natural regeneration to hasten the healing process.
A few moments later, as he exhaled a breath of black smoke, his injuries had fully healed.
Wasting no time, he dismissed his Multiple Shadow Clones, absorbing all their training experience and skill proficiency once more.
Then, after a short rest, he immediately began Round Three of training.
This time, he switched back to Palm Sage Jutsu.
While Lightning Release Chakra Mode was excellent for strengthening the body, it was too intense and aggressive.
Therefore, alternating between Palm Sage Jutsu and Authority of Man was the optimal approach for gradual yet efficient enhancement.
Additionally, this frequent use of Authority of Man helped him further understand and master Yin Release, making it a win-win strategy.
Of course, the only reason he dared to do this was because his Mangekyō Sharingan had evolved into the Eternal Mangekyō Sharingan, eliminating the risk of blindness.
Otherwise, this method would have been far too reckless.
Clearing his thoughts, Seimei refocused and threw himself back into his relentless training.
And so, the days passed, one after another…
