Beyond the boost to his base stats and chakra limit, Seimei's Sharingan evolution progressed as planned during this physical transformation, finally reaching the last bit needed to complete its current stage.
As of now, its evolution progress stood at (69,999/100,000), just one step away from the minor milestone of (70,000/100,000).
The breakthrough for the Sharingan required him to perform the Mirror Heart Technique, which would stimulate his brain to produce a special chakra, triggering changes in his optic nerves.
Without that, the Sharingan might've broken through on its own during his body's transformation.
Additionally, his Byakugan, Wood Release, Lava Release, Ice Release, Storm Release, and Dust Release—his Bloodline Limits and Bloodline Elimination—gained an extra two to three hundred evolution points during this transformation, as they always did.
But compared to what they needed for their next advancement, these points were a drop in the bucket.
So, Seimei merely glanced at them before moving on.
Next up were the improvements to his Chakra Refinement Technique and Chakra Control.
The former was as steady as ever, reliably gaining 24 proficiency points per day. Over five months, that added up to roughly 3,600 proficiency points.
Currently, its proficiency had risen from LV8 (3,480/50,000) to LV8 (7,032/50,000)—still a long way from the next level-up.
As for the latter…
Thanks to his shadow clones intensely practicing the fusion of seven chakra nature transformations, combined with the need to control sage chakra throughout his Limit of the Body training, its proficiency growth wasn't slow.
In just five months, it had gained over 16,000 proficiency points.
However, since it had already broken through to LV9, requiring a massive 100,000 points to level up again, it wasn't something he could achieve anytime soon.
Still, its proficiency was already past the halfway mark. At this rate, it would take at most a year and a half to reach the next level.
That wasn't a short amount of time, but it wasn't too long either.
Seimei held a bit of anticipation for it.
Based on past experience, any skill that broke through from LV9 to LV10 would see a massive boost in effectiveness.
And since Chakra Control focused on perfecting chakra manipulation, he could expect a significant increase in his control over chakra once it leveled up.
When that happened, whether he was practicing skills or strengthening his body, he'd be able to conserve a ton of chakra.
Phew…
Letting out a soft breath, Seimei pushed those thoughts aside.
His gaze swept over the status panel again, landing on the Sharingan's evolution progress at (69,999/100,000).
If he used the Mirror Heart Technique now to stimulate its evolution, he estimated it would take just ten minutes to break through.
But…
He sensed his condition again, feeling the ease brought by the perfect balance of mind and body.
In the end, he decided against it.
It was already late, so he could wait until tomorrow to make the breakthrough.
This would give him a full night to let his mind and body further harmonize, reducing the negative effects of any future imbalances.
"Alright, that's the plan!"
Muttering to himself, Seimei made up his mind.
Wasting no more time, he got up, flickered a few times, and arrived at the cabin.
After a quick wash by the stream, he entered the cabin and settled in to rest.
Though the recent transformation had washed away much of his fatigue, the moment he lay down, he fell asleep almost instantly.
The night passed quietly.
…
The next day, Seimei woke up early.
He headed to the stream, quickly washed up, then downed several enhanced soldier pills to fill his stomach.
After that, he used the Body Flicker Technique, leaping a few times to reach the clearing in the center of Moon Island.
Finding his usual training spot, he sat cross-legged and began performing the Mirror Heart Technique to stimulate his Sharingan's evolution.
Ten minutes flew by.
As another surge of special chakra flowed into his eyes, his Sharingan activated on its own.
Along with it came a powerful wave of mental pressure.
In that moment, Moon Island fell silent, as if the world itself held its breath.
A potent mental fluctuation radiated from Seimei, spreading outward with faint signs of spiraling out of control.
Fortunately, it didn't last long.
Seimei quickly regained his focus and began reining in the mental energy.
After about half an hour, he successfully pulled all of it back into his body.
With that, the mental pressure enveloping the island vanished.
Sensing his condition carefully, Seimei realized his mental energy had just surged significantly.
Even without checking his panel, he knew his Mental stat had increased by one point.
Just to be sure, he opened the panel and confirmed it. As expected, his Mental stat had gone from 37 to 38.
This meant his mind and body were once again out of balance.
And since the gap between base stats grew larger the higher they went, the pressure from this imbalance was noticeably stronger this time.
Thankfully, after last night's harmonization of mind and body, his tolerance for this imbalance had improved significantly.
For now, it wasn't a big deal.
But it was clear that as his base stats continued to rise, he'd need to minimize the duration of these imbalances to avoid any unexpected issues.
As for how to do that…
It was simple: just control the timing of his Mental and Constitution stat increases.
But that was a concern for later—not important right now.
Clearing his mind, Seimei adjusted his condition. Once everything was ready, he began testing the changes brought by this Mental stat increase.
Just like after a Constitution stat boost, he needed to test the growth in his theoretical chakra limit and chakra recovery speed after a Mental stat boost.
Only by understanding these changes could he better plan his future training.
With that in mind, Seimei fully activated his Chakra Refinement Technique to tap into his potential.
Time ticked by, second by second.
After about ten minutes, he stopped.
Focusing on his body, Seimei carefully sensed the changes over those ten minutes.
Then, comparing the increase in his chakra limit, he estimated the growth in his potential.
Soon, he reached a conclusion: this Mental stat increase had boosted his potential—his theoretical chakra limit—by roughly 7.5 million points.
While this wasn't as massive as the 20 million point increase from yesterday's Constitution stat boost, it was still 1.5 million points higher than the 6 million point increase from his previous Mental stat boost, when it went from 36 to 37.
As for his chakra recovery speed…
After testing, Seimei found it had increased by 4.5 million points. Again, this was less than the 10 million point boost from yesterday's Constitution increase, but it was 1 million points higher than the 3.5 million point increase from his last Mental stat boost.
As a result, his daily chakra surplus now reached 21.868 million points (calculated as 7.368 + 10 + 4.5).
Of course, this was temporary.
As his body underwent another transformation and its capacity increased, he'd need to invest more chakra to train at full speed.
Plus, his Sharingan could now continue evolving, and the six hours spent on the Mirror Heart Technique would have to be accounted for.
So, how much chakra he'd actually have left would depend on further testing.
