Under Hii Kōri and Karura's guidance, Pakura's chakra manipulation capabilities made great progress.
Utilization efficiency, circulation speed and fluidity—these details easily overlooked often determined combat flow by the slightest margins.
Accumulating advantages while seeking opponents' openings to secure victory. This was routine ninja combat.
Lacking exceptional chakra quantity, Pakura naturally needed this idea.
Her temperament's stubbornness, competitiveness, and desire for strength occasionally reminded Hii Kōri of a past acquaintance—a regular cursed tool customer. That acquaintance's circumstances before Hii Kōri's death were far from favorable.
Based on this familiarity, he couldn't possibly ignore Pakura.
Karura, while tutoring Pakura, learned medical ninjutsu basics alongside Hii Kōri.
Though temperament concealed it, Karura's delicate chakra manipulation revealed considerable talent in medical ninjutsu and Sand's unique Sand Manipulation.
In fine operations of small amounts of sand, she might surpass Rasa—more adept at large-scale Sand Manipulation.
Hii Kōri, having long noted her chakra circulation, anticipated this. Even Pakura, knowing her longer, hadn't realized.
Karura's school demeanor was uniformly kind and gentle—never conflicting with others, let alone displaying strength.
Such a soft-natured, rabbit-like girl seemed ill-suited for ninja life. Yet her determination to firmly confront Pakura for Hii Kōri's sake demonstrated how seriously she took this.
Receiving such one-sided kindness, Hii Kōri couldn't completely ignore it.
He wasn't that cabbage-loving, mango-faced police officer allergic to kindness.
If you dislike conflict, learn medical ninjutsu. Healing others' pain with your own hands should resonate with you. Thus beating around the bush, he'd handed Karura medical ninjutsu notes.
How brightly that perceptive girl smiled then—Hii Kōri felt he'd never forget.
Previous life included, his resume contained little cause for others' smiles.
Crazy scientist reincarnated another world, gaining family and love, thawing heart—sounds quite light novel-esque.
Ah? Asking where Hii Kōri got medical ninjutsu?
Obviously fled from Chiyo.
Did Hii Kōri not notice? Karura and Pakura's actions absolutely involved that old hag Chiyo's fueling the fire.
Thus of course demanding "operating expenses." As top-five pharmacological master worldwide, scraps of her knowledge sufficed for Karura's graduation.
Of course, Hii Kōri wasn't so altruistic as free help based on mere favor.
In this study group, he benefited Most.
A spiritual elevation? Even mentioning it made him unable to keep a straight face. His mental state was more like "falling into" or merging into this world rather than elevation. Anyway, he'd fully adapted.
Furthermore—previously envisioned divided thinking made rapid progress. He'd completed twofold, advancing toward threefold.
Atlas Institute's foundation, divided thinking wasn't merely multitasking.
It divided thought into multiple thought loops, all aligned purpose, exchanging information, achieving multiplicative effects.
Fourfold divided thinking enabled 256 parallel thoughts—like high-speed intelligences operating seamlessly toward shared goals.
Hence, divided thinking's difficulty rose exponentially. Even basic twofold was exceptionally beyond the norm. By ninjutsu rankings, unquestionably S-rank.
Given potential for self-harm, the classification of forbidden techniques wasn't an exaggeration.
Without Hii Kōri's superhuman spiritual strength and Uzumaki's vigorous life... Force, he'd never attempt such a brain-intensive technique.
This originated from a fantasy work's "seemingly worth trying" technique—the principles and training process are completely black boxes. Current results are purely "hardware" brute force.
Essentially, a technique only usable by him. Spirit, vitality, control precision, computational power—any insufficient, divided thinking could literally burn out the brain.
Such a dangerous technique, Hii Kōri revealed to none.
Firstly, explaining how he achieved it impossible. Secondly, wasting time teaching something 99% impossible.
Previous life, he often heard "one person's talent can no longer advance the world." Each time, he'd point at the speaker's nose and tell them to study advanced mathematics.
Difficulty-wise, basically identical.
Additionally, using Pakura as a sparring partner, Hii Kōri mastered several Wind Release techniques.
Unlike Karura, the martial arts-style Pakura better kept pace with his rhythm—both in ninjutsu and Taijutsu.
Having analyzed the workings of Wind Release, he'd begun to grasp the "chakra's core."
Chakra circulation and refinement, the mixing ratio of mental and physical energy, the instantaneous limits of absorption—all chakra fundamentals now firmly etched in his mind and body.
Finally able to address the issue of "cursed energy."
Most importantly—as a cursed tool master, with Pakura's assistance, Hii Kōri forged a weapon perfectly suited to him.
