"Inhale~~~ Exhale~~~"
Taking a deep breath, then letting it out slowly.
Seimei calmed his mind.
Now that he'd tested how much chakra the Four-Tails could supply daily, the next step was figuring out how to distribute it.
First up was a plan he'd originally intended to tackle but had shelved due to a lack of chakra.
The idea? Combine the "Transcription Seal," "Lockheart Seal," and "Self-Karma Curse Seal" with the Flying Thunder God mark to create a new sealing technique. It'd be something that could control others and keep secrets—similar to the "Tongue Calamity Eradication Seal"—while also serving as a teleportation coordinate for the Flying Thunder God Technique.
For this, Seimei planned to invest 200,000 chakra points and spend a week crafting a prototype. After that, he'd adjust the investment as needed to level it up.
It was easy to see that once he perfected this sealing technique, pulling off covert operations in the future would get a whole lot easier.
Next came training his various skills.
Right now, on his skill panel, "Earth Release: Earth Dragon Bullet Technique" had just hit perfection, so no more investment was needed there.
"Chakra Control" passively improved through insights gained from mastering other skills, so it didn't require any chakra either.
As for "Chakra Refinement Technique," its proficiency grew in a unique way—passively running 24 hours a day, maxing out at 24 proficiency points daily. Pouring in more chakra wouldn't help.
Then there were "Izanagi" and "Izanami." He'd tested these long ago and found that, due to the limitations of practicing with shadow clones, each could only gain up to 500 proficiency points per day.
Any more than that, and the effort wouldn't match the reward.
So, no need to dump extra chakra into those either.
That left him with "Fire Release: Flame Gathering Strike," "Lightning Release: Raikiri," "Earth Release: Weighted Rock Technique," and "Earth Release: Light-Weighted Rock Technique" as the skills he could pump more chakra into.
For the latter two, he'd recently split the 150,000 chakra points saved from perfecting "Earth Dragon Bullet Technique" between them, doubling their growth speed.
But even so, their overall progress was still pretty slow.
Seimei was eager to grind them up to Level 7.
From there, he'd build on them to develop "Earth Release: Super Weighted Rock Technique" and "Earth Release: Super Light-Weighted Rock Technique," deepening his understanding of earth-attribute chakra nature transformation. Naturally, the faster, the better!
So, he decided to allocate another 300,000 chakra points, splitting it evenly—150,000 for each—to boost their investment.
With that, the chakra poured into them would double again, jumping from 150,000 to 300,000 points daily.
Their daily proficiency gains would double too, going from 1,000 to 2,000 points.
At that rate, excluding today's accumulated proficiency, it'd take just five and a half days for them to hit Level 7 (0/0)—the perfected state.
And five and a half days? That lined up perfectly with the last day of this training cycle.
In other words, starting next cycle, he could move on to developing and practicing "Super Weighted Rock Technique" and "Super Light-Weighted Rock Technique."
Pulling his thoughts together, Seimei glanced at his remaining chakra.
200,000 plus 300,000 equaled 500,000!
That left him with 1,000,000 chakra points to play with.
After some thought, he decided to split it into two chunks. First, 250,000 points would go straight into "Fire Release: Flame Gathering Strike."
With that, his daily investment in that technique would hit 750,000 points, boosting its proficiency gains from 2,000 to 3,000 points per day.
At that pace, it'd take about a month for it to approach the peak of Level 9.
Then, it'd be time to push for the breakthrough.
Once he succeeded and raised it to the S-rank skill cap of Level 10 (0/0), it'd mean he'd fully mastered the technique.
By then, his grasp of fire-attribute chakra nature transformation would pretty much meet his goal.
But that was easier said than done.
Shaking his head quietly, Seimei didn't dwell on it. Instead, he calculated how the remaining 750,000 points would boost "Lightning Release: Raikiri."
Yep, he planned to dump all 750,000 into "Raikiri."
That'd bump his daily investment in it from 186,000 to 936,000 points.
At an average of 1 proficiency point per 200 chakra, 936,000 points daily would net him 4,680 proficiency points.
That speed was leagues ahead of what it used to be.
At this rate, it'd take just two days to grind "Raikiri" to Level 7.
Another half month, and it'd hit Level 9.
And that wasn't even its limit.
Though "Raikiri" and "Chidori" were essentially the same technique—and "Chidori," as an A-rank jutsu, capped at Level 9 (0/0)—"Raikiri" had stronger chakra (cohesion), meaning it could likely break through to Level 10.
That'd take another 20 days.
Still, whether it stopped at Level 9 or pushed to Level 10, the total time would be way shorter than the three or four months he'd originally estimated.
And that was the payoff of capturing the Four-Tails.
But his gains didn't stop at more usable chakra. The Four-Tails' own Lava Release offered him a nice bonus too.
Unlike the bland Seven-Tails, the Four-Tails naturally wielded Lava Release. Drawing chakra from it daily, Seimei could pick up bits and pieces of how to blend earth- and fire-attribute chakra nature transformations.
Those insights might not seem like much in the short term, but over time, as they piled up from quantity to quality, he might just master Lava Release.
This wasn't just wishful thinking—Old Purple was living proof.
That guy had nailed Lava Release precisely because he'd become the Four-Tails' jinchuriki, constantly exposed to its chakra until he gradually grasped that kekkei genkai.
With his foundation from training other skills, Seimei would only pick it up faster.
Of course, his interest in Lava Release wasn't about craving its power.
To him, Lava Release was just okay.
His real reason for wanting to master it? Fusing all seven chakra nature transformations at once to create a kekkei mora was insanely tough—borderline impossible.
So, ages ago, he'd decided to break it into steps: start with kekkei genkai, move to kekkei tota, then finally reach kekkei mora, tackling it bit by bit from easy to hard.
And Lava Release, born from fusing two chakra nature transformations, was a solid first step.
