In the blink of an eye, another day had passed.
That morning…
After dispelling the Multi-Shadow Clone Jutsu once again and absorbing all the experiences and memories his clones had gathered over the past hour, Seimei felt a breakthrough.
He opened his status panel and took a quick glance.
Sure enough, his Genjutsu: Bringer-of-Darkness Technique had advanced from Level 8 to the maximum limit of an A-rank skill—Level 9 (0/0)!
A sudden wave of enlightenment washed over him.
Seimei closed his eyes again, carefully sensing this new understanding.
A few moments later, he opened them.
A sharp gleam flashed across his pupils.
At that moment, his comprehension of the Bringer-of-Darkness Technique, and even the essence of Yin Release, had reached a whole new level.
The latter wasn't too surprising—after all, practicing genjutsu naturally strengthened one's Yin Release abilities, so it wasn't anything to be overly excited about.
But the former…
This was different.
Created by Senju Hashirama specifically to counter the Uchiha clan's Sharingan, the Bringer-of-Darkness Technique was undeniably powerful.
It was common knowledge that among the five senses, sight was the most crucial. The information it provided far exceeded that of the other senses.
Because of this, if a ninja's vision was taken away, their combat effectiveness would plummet.
Previously, when Seimei cast this technique, it could only affect a single target.
But now…
As long as his target was within his field of vision and made eye contact with him at the moment the jutsu was activated…
He could channel the power of genjutsu through his eyes, projecting it onto multiple enemies at once.
In other words, after reaching its perfected state, this technique had evolved from a single-target attack into one that could now affect both single and multiple enemies alike.
If that were the only improvement, Seimei might have been pleased, but he wouldn't have paid it too much attention.
The real game-changer was this:
Even when affecting multiple people, the genjutsu's effectiveness did not weaken significantly.
And that… was what truly caught Seimei's interest.
After all, even the Uchiha clan, wielders of the Sharingan, had difficulty escaping this jutsu.
Let alone anyone else.
With this in mind, it was clear—this technique had just become one of his ultimate trump cards.
Of course, such a transformation didn't come without a price.
The most obvious drawback was that casting the technique on multiple people simultaneously greatly increased both chakra consumption and mental strain on the user.
But for Seimei, this wasn't much of a problem.
Right now, his chakra reserves were already nearing 400,000 points—a minor energy drain like this wasn't even worth worrying about.
As for the mental strain…
Seimei glanced at the evolution progress of his Sharingan, which was approaching its critical point, and felt completely unfazed.
Once his Mangekyō Sharingan evolved into the Eternal Mangekyō Sharingan, his mental strength would experience a significant boost.
At that point, handling additional strain would be effortless.
Even now, with his 23 points in Spirit, he could control up to ten elite jonin simultaneously without issue.
So really, there was nothing to be concerned about.
Shaking his head, Seimei put the matter aside. Instead, he focused on an even more pressing question:
How should he allocate the 250,000 chakra points he was now saving daily?
His gaze swept across the status panel, moving from skill to skill, before settling on one—
Nirvana Temple Jutsu.
This jutsu had started at the same level as Bringer-of-Darkness Technique, but due to less chakra investment over time, it had only reached Level 8, with barely 40% progress toward Level 9.
In other words, it still needed nearly 30,000 proficiency points to reach Level 9 (0/0), just like Bringer-of-Darkness Technique.
At his current rate, it would take roughly twenty more days to achieve that.
But Seimei wasn't willing to wait that long.
So, he decided—
He would invest all 250,000 newly freed chakra points into it.
With this change, his daily chakra intake would increase from 140,000 points to 390,000 points.
If he used up all that chakra, his daily proficiency gain would jump from 1,370 points to 3,820 points.
At that rate, it would take less than eight days for Nirvana Temple Jutsu to reach its perfected state.
Satisfied with his calculations, Seimei nodded to himself.
He then closed his status panel, not wanting to waste any more time.
Once again, he raised both hands, forming the Ram hand seal—
And cast Multi-Shadow Clone Jutsu.
Poof!
With a burst of chakra-infused smoke, dozens of identical clones appeared in the training area.
This time, however, when assigning training tasks, Seimei specifically prioritized the Nirvana Temple Jutsu.
The chakra allocation for this technique more than doubled, meaning his old training regimen was no longer sufficient.
He needed to make adjustments.
And this…
Was just the beginning.
In the next few training cycles, he planned to continuously fine-tune the number of clones working on Nirvana Temple Jutsu, based on their efficiency.
Eventually, he would find the perfect balance between training goals and chakra expenditure.
For now, the uneven chakra distribution meant that by mid-afternoon, several skills would finish their daily training goals, freeing up more clones to focus on Nirvana Temple Jutsu.
This would allow him to gradually reduce the number of clones working on it at the same time.
Otherwise, he'd have to account for energy wastage.
Shaking his head, Seimei stopped overthinking.
Once his clones dispersed to begin training, he immediately resumed his own practice.

### Two Days Later…
That afternoon.
On a remote island, atop a familiar giant boulder…
As Seimei once again cast Reflection Mind Jutsu, stimulating his mental energy to produce special chakra, his Sharingan evolution progress suddenly reached completion.
A sense of perfection filled his mind.
"This is…"
His eyes snapped open, gleaming with excitement.
He quickly opened his status panel and looked at his Sharingan's progress.
Just as he had suspected—
After more than half a month of focused training, his Mangekyō Sharingan evolution had finally reached its critical point—(50,000/50,000)!
At this moment, Seimei felt an overwhelming urge to immediately begin the evolution into the Eternal Mangekyō Sharingan.
But after a brief internal struggle… he forced himself to hold back.
Even though evolving now wouldn't be too risky, it was still not entirely without danger.
The problem was…
His Spirit attribute was already significantly higher than his Physique.
If his mental power increased even further without a corresponding boost in physical endurance, he could face severe consequences.
In the worst case…
He could end up with a genetic disorder—just like Uchiha Itachi.
That was not an outcome Seimei wanted.
So, for now, he chose patience.
His body transformation was only a few days away.
It wasn't worth the risk.
With that thought, Seimei gradually calmed down.
The time would come soon enough.
