Chapter 5: One Click Full Level

"This Qin Yu seems to be getting ahead of himself. Mastering an A-rank Ninjutsu isn't easy. Even seasoned shinobi take over a month to learn it through trial and error. How can he succeed in just three days?"

"Well, young people are always like this, eager to prove themselves," Yūyue Cangwu patted Inuzuka Fū's shoulder and said. "I just hope Qin Yu realizes that some things can't be rushed."

Outside the cave, in a secluded valley.

Qin Yu unrolled the Lightning Release scroll and immediately activated his Mangekyō Sharingan.

His crimson eyes swirled ominously as he focused on the intricate jutsu formula. This was the power that had earned Kakashi Hatake the title of Copy Ninja.

For a shinobi, there were two crucial stages in learning a jutsu: acquiring the basics and mastering the technique.

But with the Mangekyō Sharingan, Qin Yu could bypass the first step entirely. His mind recorded the jutsu instantly, leaving only the need for proficiency. And with his system's one-click full-level function, even mastery was achievable in seconds.

At this moment, Qin Yu was practically running a cheat code, an overpowered buff that accelerated his growth unnaturally.

Let's see how far this power goes!

A notification flashed in his mind.

"Ding! Detected high-speed hand seal execution. Would you like to max out this skill?"

"Max out immediately."

Qin Yu's hands moved in a blur, his chakra surging as he molded its nature transformation precisely.

"Lightning Release: Raiten!"

The final seal snapped into place, and the sky responded.

A deep rumble echoed overhead as nine bolts of lightning, like dragons emerging from the abyss, crashed down upon the rocks ten meters away.

BOOM!

The impact was deafening.

Chunks of stone shattered under the devastating force, leaving a ten-meter crater in the ground. Smoke and residual electricity crackled in the air.

Qin Yu stared at the destruction, unable to suppress his amazement.

The Lightning Release: Raiden Drop jutsu, according to the scroll, allowed a shinobi to channel natural lightning from the atmosphere to strike their target.

But what he had just done went beyond that.

"Could it be the one-click full-level system?" Qin Yu muttered.

He recalled something Uchiha Madara once said: There are no weak jutsu, only weak shinobi.

A simple Fireball Jutsu in the hands of an Uchiha could rival a large-scale technique.

Perhaps that's what had happened here. His full-level mastery had turned a standard A-rank jutsu into something far deadlier.

However, the technique had consumed nearly one-tenth of his chakra reserves.

"Ding! Lightning Chakra Affinity maxed out."

"Ding! Lightning Release: Raiden fully mastered."

"Ding! Thunder Elemental Perception maxed out."

The system notifications confirmed Qin Yu's suspicions.

As he observed the crater, another jutsu surfaced in his mind—one of the most devastating Lightning Release techniques ever used in battle.

S-rank: Lightning Release: Kirin.

Unlike most ninjutsu, Kirin wasn't reliant on a shinobi's chakra alone. It utilized natural lightning, making it nearly unavoidable and explosively powerful.

Even the Rasenshuriken, the pinnacle of Wind Release, had difficulty matching Kirin's sheer destructive potential.

Yet in the original timeline, Sasuke had only used Kirin once, making it one of the most underutilized techniques in the entire series. Many fans had lamented its lack of a second appearance.

Qin Yu, however, saw an opportunity.

With hundreds of Kumogakure shinobi closing in—including the infamous A-B combo—it was bound to be a grueling battle.

If the fight dragged on, his chakra reserves—despite the Mangekyō Sharingan—would be depleted.

Kirin might be the key to turning the tide.

By manipulating atmospheric conditions, he could drastically reduce its chakra cost, allowing him to strike at near-lightning speed with a wide-area attack.

And with his system's abilities, the odds of successfully recreating Kirin were extremely high.

It could be his trump card.

Three days passed in the blink of an eye.

"Ding! Lightning Release: Kirin fully mastered."

The familiar system notification filled him with relief.

He severed his connection with the dense thunderclouds above.

The ominous storm dispersed instantly, the suffocating pressure lifting as if it had never existed.

"Good thing I had the one-click full-level system. Even Lightning Affinity Perception maxed out, or else perfecting Kirin would have been impossible," Qin Yu murmured as he deactivated his Sharingan.

This training had revealed something crucial—the greatest weakness of the Uchiha clan.

Their chakra reserves were lacking.

No wonder every major Uchiha in history had struggled with prolonged battles.

Even Madara Uchiha had resorted to transplanting Hashirama's cells to overcome this limitation.

If Qin Yu wanted to stand at the pinnacle of the shinobi world, obtaining the Sage Body was a necessity.

But that was a concern for later.

For now, war was coming.

As he emerged from the valley, the 27 Konoha shinobi stationed nearby had already assembled.

They were battle-ready, their eyes filled with unwavering resolve.

Even though they were up against hundreds of Kumogakure's finest, including the terrifying duo of A and B, they refused to back down.

Behind them lay the Fire Nation's heartland. If they fell here, Konoha—and their families—would be in grave danger. Retreat was not an option.

"Qin Yu, if you haven't mastered the A-rank technique yet, don't be discouraged," Inuzuka Fū said, his voice steady despite the tension in the air.

"Even veteran shinobi need over a month to perfect something like that."

He glanced at the sky, where the residual thunderclouds still lingered.

"The sudden storm made us think Kumogakure was already launching an ambush. It was oppressive."

"Inuzuka, don't jinx us." Yūyue Cangwu shot him a glare.

"Listen, kid. If things go south, don't push yourself too hard. If it comes to it, get the intel back to the village. A single jutsu isn't worth your life."

Qin Yu looked at them all.

A few days ago, these shinobi had viewed him as just another rookie.

But after witnessing his abilities firsthand, their skepticism had turned into something else—expectation.

They believed in him.

Qin Yu exhaled slowly.

It was time to prove that belief was not misplaced.
