Taking the e Teique as an Example

  When Link first learhe e Teique, the chakra allocated to it could only separate his limbs into basic parts—arms, head, legs, and torso. Hands and fingers were treated as a single unit with the arm. After extending the duration of the e Teique to one minute, he mao separate individual fingers.

  Even when he pushed the teique to its limits, ing over 80% of his chakra in a single use, he still couldn't break apart flesh and muscle.

  What he could do, however, was detach fingernails, hair, eyeballs, ears, and even his nose. While horrifying, this didn’t seem particurly useful in bat.

  The sheer shock factor, however, was definitely on another level.

  Duriing, Link ohought he could run the most terrifying haunted house ba his inal world. Watg himself in the mirror without a face, hair, eyes, or ears was an experiehat filled even him with deep unease.

  When his body parts separated, there were no gory wounds left behind. Instead, the areas where his body split were smooth and seamless. Holding his detached eyeball to i himself in the mirror was dht uling.

  Outside bat, these abilities had their perks. For instahrowing ao eavesdrop or using an eyeball to spy was incredibly practical.

  But ing 80% of his chakra for such as was far from feasible. He’d be left drained, a sitting duck if any bat occurred afterward.

  And no, soldier pills weren’t some miraculous remedy. Their chakra restoration effects didn’t stack, couldn’t fully replenish his reserves, aainly couldn’t push his chakra beyond its natural limit.

  Soldier pills, acc to the Book of Soldiers, are surprisingly simple in position:

  1 tablespoon of vegetable juice

  6 bean snacks

  8 small biscuits

  10 mixed nuts

  2 teaspoons of sesame seeds

  A pinch of shichimi spice

  25 raisins

  Link didn’t fully uand how such basigredients could restore chakra, but they were affordable enough to include in his routine.

  However, ing them regurly still added up to a signifit expense over time.

  Iingly, acc to Chōji in the manga, there was a "secret" variety of soldier pills rumored to ehree days and nights of tireless bat, with stimunt aive effects. Link hadn’t been able to find or verify the existence of such pills.

  Because of its random nature, Link’s Substitution Teique cked a clear development path. He still couldn’t trol what type of substitution he’d summon, limiting its strategic applications.

  The Binding Teique was another challe relied on money, and Link wasn’t willing to spend on experimental uses. Fake money, or "currency" that he didn’t reize as legitimate, couldn’t serve as a target for the teique. And items like spiritual currency did in the world of Naruto.

  The Earth Release: Headhueique was an energy hog, ing too much chakra for what essentially amouo a hazy genjutsu effect. Without cooperation from an oppo, developing this teique further seemed futile.

  Initially, Link had high hopes for the Transformation Teique.

  Uhe inal version, which created mere illusions, his variant produced tangible transformations. Theoretically, this opened a vast range of possibilities.

  Unfortunately, it came with severe limitations. He could only transform into objects or forms he thhly uood.

  For example, he could perfectly recreate his father’s sword because he had an intimate uanding of its texture, sharpness, length, material, and stru. Without suowledge, transformations were impossible.

  This realization hit him hard when trying to replicate objects from his previous life. Things he thought he knew well, like gadgets or tools, turned out to be bnk spaces in his memory. What materials were they made of? What were their internal structures? rinciples goverheir operation?

  So far, the most bat-effective item he could transform into was an explosive tag.

  But explosive tags were single-use items. What was he supposed to do, rush at an oppo, transform into a tag, and self-detonate?

  Even imagining it felt absurd. And if the explosion damaged his body beyond the recovery capabilities of the e Teique?

  An expendable tool? More like an expendable self.

  As for transf into mythical beasts or Saiyans—those were even further from reality. Did he know how the Uzumaki bloodline worked by disseg a body? Could he uand a tailed beast’s meics just by examining it?

  Pure nonsense.

  In early experiments, Link sidered transf into water, mud, or other substances. He envisioned a form of elementalization, borrowing ideas from other universes.

  But the problems were immediate and obvious. His Transformation Teique didn’t grant immunity to damage, nor could it adjust his size or mass. He would remain his inal form, just "coated" with the appearance of another substance.

  For instance, if he turned into a "mud man," he would be just as vulnerable—if not more so. A siack could scatter his body, or a bit of fire could reduce him to ash.

  Urue elementalization, which allowed trol over the corresponding element, his transformations were merely etic. For damage mitigation, the e Teique was a much better alternative.

  Even with increased chakra iment, all he could achieve was sg the size of his transformations—not improving their effectiveness or versatility. This left the Transformation Teique in a frustratingly awkward state.

  With no clear development paths for his five jutsu, Link shifted his focus to being a in. He hoped the promotion would grant access to eiques that might offer breakthroughs.

  However, his limited chakra meant that many ninjutsu options, especially rge-scale elemental teiques, were impractical. The high energy costs made them unsuitable for real bat.

  Instead, Link aimed for teiques with promising names or cepts.

  Kirin (not yet ied)

  Lightning Bde (S-rank, prohibitively expensive chakra cost)

  Flying Thunder God (S-raremely high learning difficulty)

  Mystical Palm (A-rank, impractical chakra ption)

  Adamantine Sealing s (likely a bloodline limit)

  Dead Soul Teique (only seen in the manga)

  Super Beast Imitating Drawiremely rare specialty jutsu)

  While these teiques held great potential, their acquisition and mastery were far beyond his current reach.

  For now, Link could only dream of being a powerful, god-like figure with abilities like Flying Thunder God. Instead, he focused on ial progress aed new ideas with his existing jutsu.

  But mostly, he stuck to the basics—training his body.

  Because at the end of the day, foundations matter most.
