Rebuilding Uchiha By Removing Fugaku

[Congratulations on obtaining the optimized Water Release: Water Dragon Bullet Jutsu!]

[Water Release: Water Dragon Bullet Jutsu (Optimized Version): By using scientific ninja tools to inscribe ninjutsu circuits within the body, chakra can instantly flow through these circuits, enabling the jutsu to be cast without the need for hand seals. Practitioners should note the following during training:...]**

[Do you want to learn this ninjutsu? Y/N]

Toki was momentarily stunned.

The optimization didn't lower the difficulty of practicing the jutsu; in fact, it made it more advanced. The Water Dragon Bullet Jutsu, originally a B-rank technique, was upgraded to A-rank. However, the system didn't provide clear information about the enhanced power.

After some thought, Toki understood.

The ranking of ninjutsu is based on its difficulty to master, not necessarily its raw power. Forbidden jutsu, for instance, are categorized as such because of their inherent risks, not their strength.

Similarly, an S-rank jutsu isn't always stronger than an A-rank jutsu. The actual strength of any technique depends on the amount of chakra used and the practitioner's control over its nature transformation.

The Great Fireball Jutsu became iconic for the Uchiha clan because its power could be scaled based on chakra usage, and it was relatively easy to master. In contrast, techniques requiring higher chakra thresholds or strict form controls were less commonly used by the clan.

The optimized Water Dragon Bullet Jutsu eliminated the need for hand seals entirely. To put it simply, the casting time was reduced to zero. In modern terms, it was like clapping your hands and instantly summoning a water dragon—avoiding the original version's 44 seals, as Kisame did.

While Kakashi's hand speed allowed him to execute 44 seals in mere seconds, in high-level battles, even a second could determine the outcome.

The concept of hand seals originated with Indra.

In the earliest days of the ninja sect, there were no hand seals, but some disciples with weaker chakra control struggled to use ninjutsu. Indra discovered that forming different hand seals directed chakra along specific meridians in the body, enabling the use of ninjutsu.

Each hand seal corresponded to a specific chakra flow and form, leading to the creation of different jutsu. The chakra flowing from the internal organs carried unique attributes, resulting in elemental diversity.

This is why the Ninja Academy teaches the relationship between hand seals and elemental jutsu. Understanding an opponent's hand seals can reveal the type of ninjutsu they are casting, allowing countermeasures or preemptive avoidance.

For example, the Tiger Seal is a standard seal for Fire Release jutsu. When Kakashi formed it behind Naruto during his prank Thousand Years of Death, it shocked Sakura and Sasuke.

Some talented ninja, like disciples of the ninja sect, bypass hand seals entirely, controlling chakra flow directly within their bodies.

The Second Hokage, Tobirama Senju, famously reduced the Water Dragon Bullet Jutsu's seals to five. However, this didn't mean the technique required only five seals—it meant Tobirama could execute the chakra flows for the remaining seals instinctively.

For example, Tobirama's simplified sequence was [Rat-Ox-Hare-Tiger], while Ten Thousand-Year Genin Kosuke Maruboshi's sequence was [Rat-Ox-Tiger-Snake-Horse-Rooster]. This difference stemmed from individual chakra control methods.

Figures like Hashirama Senju and Madara Uchiha, as reincarnations of Asura and Indra, reached such a pinnacle of chakra control that they could perform any ninjutsu with just a clap of their hands.

After some consideration, Toki selected "Yes" to learn the optimized jutsu.

A strange touchpad emerged from the computer.

[Please place your hand on the pad.]

Toki complied, feeling a brief tingling sensation in his meridians before it vanished.

[Skill learned successfully.]

Toki frowned. "That's it? How do I use it?"

The machine seemed to sense his confusion and explained:

[To use the ninjutsu, activate the circuit through consciousness and inject the corresponding chakra.]

A training dummy rose from the floor, and a light barrier surrounded Toki and the target.

Raising an eyebrow, Toki thought, Consciousness? Inject chakra?

Striking a theatrical pose, he shouted internally: "Go, Pikachu!"

Instantly, the chakra in his body aligned with the Water Dragon Bullet's circuit, and a massive water dragon materialized from his side, roaring toward the target.

With a deafening crash, the dragon struck the target, its scattered force confined by the light barrier.

Toki narrowed his eyes. The optimized Water Dragon Bullet's power far surpassed his manual version, despite his mastery over chakra control with the Mangekyō Sharingan.

This optimized jutsu impressed Toki. While he could already perform ninjutsu without seals, this technique offloaded the mental burden of controlling chakra flow by embedding it into a pre-designed circuit.

He sighed, "What is this? An artificial ninjutsu cannon?"

It felt like his clan was venturing further into advanced black technology.

Turning his attention to the [Deduction] option on the screen, Toki's curiosity grew. This feature was newly unlocked with the Ninjutsu R&D Center's second-level upgrade.

"What kind of black technology is this?" he muttered.
