Naruto: Get Stronger by Spoiling My Sister

Neji smiled, sincerely. Although this reward seemed… a bit lackluster compared to those he'd received before, it was exactly what he needed most at the moment.

Ever since arriving in this world and obtaining the system, Neji had advanced at an unimaginable pace. In just two short months, he'd leapt from chunin-level to elite jonin-level strength. In fact, even facing Kage-level opponents no longer fazed him.

Yet, despite all this, there remained one crucial limitation that had constantly held him back a shackle that prevented him from unleashing his full potential.

But now, that shackle had begun to loosen.

"Host patted Shouju's head. Reward obtained: [Chakra Amplification x10]."

The system's voice was as cold and mechanical as ever, devoid of emotion. But to Neji, those words struck like a crashing wave upon his chest, sending a thrill through his entire being.

A warm surge coursed through his body, stimulating every cell, leaving him feeling refreshed and unburdened. Within moments, he felt significantly more powerful his strength fully charged, his mind sharp and alive, as if he were standing atop the world.

"Haha..." Neji couldn't contain his excitement. This was the feeling he'd longed for the freedom from chakra constraints, the ability to fight without holding back.

He still remembered his first clash with Orochimaru. He'd been completely overpowered and had no choice but to threaten Orochimaru with the All-Killing Ash Bones. Yet before he could even activate it, he was already running out of chakra. It was then that he finally understood Kakashi's struggles.

Obito had Hashirama's cells and never ran out of chakra. With just a single Mangekyo Sharingan, he could weave in and out of the Five Kage like a ghost. But Kakashi? He had the same eye, yet just two uses of Kamui left him spent and reeling.

To put it nicely, he lacked chakra. To put it bluntly, he was crippled no matter how strong the ability, if the hardware couldn't keep up, it was useless.

Neji calmed himself and estimated silently, "With my chakra multiplied tenfold, I'm probably somewhere between elite jonin and Kage-level now."

"But even if I'm not quite at Kage-level chakra, my actual combat strength is at its very peak." He smirked as his gaze fell on Shouju.

I do appreciate the gift you've brought me... but people walking different paths can't walk together.

Shouju's heart skipped as she met Neji's cold, detached stare. Without hesitation, she activated her petrification technique and lashed out with a whip-like kick.

Neji caught her ankle with a backward sweep of his hand. His eyes flicked toward the iron rod, melted and deformed by his Flaming Rotation earlier. A cold sneer played on his lips.

"You don't even have a weapon anymore. I suggest you give up," he said darkly. "There's no point in dying an ugly death when you could at least look presentable."

"Host touched Shouju's ankle. Reward obtained: [Earth Style: Rock Lodging Destruction]."

Earth Style: Rock Lodging Destruction – A jutsu that collapses rock formations using chakra.

Ah, terrain-based ninjutsu... Neji nodded, satisfied. In the right environment, this is a large-scale killing technique. It even has its own reputation.

After all, it was the same technique that had nearly crushed the Ten-Tails' Jinchuriki.

"Let go of me!" Shouju shouted in fury. Her wrists and ankles were locked down by Neji, making it impossible to break free. Rage and desperation mingled on her face.

"Relax. I won't kill you yet. You're still useful," Neji said coolly. Obviously I'm not done collecting rewards.

"Host engaged in battle with Shouju. Reward obtained: [Earth Style: Clay Rainfall]."

Earth Style: Clay Rainfall – From an overhead rift in space, sticky clay rains down onto the enemy, immobilizing them. When combined with Fire Style, it can reduce targets to molten pulp.

"Hm? There's more?" Neji blinked. This was a high-level restraining jutsu exceptionally effective. Konoha's ANBU had once used it to trap one of Pain's summoned beasts, the Giant Hellhound. Its strength was self-evident.

"Lightning Style: Thunder Spear!"

"Earth Style: Stone Spire!"

The other Root members finally moved. Taking advantage of Neji's preoccupation with restraining Shouju, they launched their attacks. A white-blue lightning spear materialized in the air and plunged toward Neji. At the same time, the ground beneath him cracked open, and a stone spire erupted upward.

"Heh... Too naive," Neji scoffed as several greenish-blue serpents slithered from his sleeves and wrapped tightly around Shouju.

"Eight Trigrams: Mountain Breaker!"

With a flick of his wrist, Neji unleashed two brilliant beams of white light. The first tore straight down, piercing through layers of floorboards. The second shot toward the oncoming Root members with devastating force.

"Fall back!"

"Earth Style: Earth Flow Wall!"

Startled, the Root ninja quickly formed seals together. Massive stone walls erupted from the earth, layering into a thick barrier between them and the attack.

Boom!

The white beam screamed through the air, tearing at the atmosphere. The dense wall of stone was chipped away piece by piece, becoming thinner and thinner but ultimately, it held. The Root members breathed a collective sigh of relief.

"Let's end this. It's about time," Neji's eyes gleamed with killing intent. One Hidden Shadow Snake Hand later, and Shouju was reeled tightly against his waist.

"Host embraced Shouju. Reward obtained: [Earth Style: Petrification]."

Earth Style: Petrification – Transforms a part or the whole body into stone, increasing size, durability, and offensive power.

"This is where your journey ends," Neji said coldly. The Root operatives every single one of them had blood of their comrades on their hands. For them, the mission always came first. Even if it meant betrayal.

"Chakra Scalpel."

A blade of chakra formed in Neji's palm, which he drove toward Shouju's heart.

"The story of Root ends here."

"Host touched Shouju's chest. Reward obtained: [Earth Style: Earthen Burial Dumpling]."

Earth Style: Earthen Burial Dumpling – Strengthens the user's physical power to unearth massive stones from the ground and hurl them at enemies.

Neji withdrew his hand. Shouju's lifeless body crumpled to the floor. He curled his lips into a cold smile as he turned his gaze toward the rest of the Root operatives.

"Root… is meant to be pulled out."

Under their tense stares, Neji walked calmly to the wall of the base. He looked at the distant group of Root nin, then shook his head.

Placing his palm against the wall, he poured chakra into it.

"Earth Style: Rock Lodging Destruction."

Let me bury you all with the jutsu I took from you.

Rumble-

The ground shuddered. Cracks spread visibly across the walls and ceiling. Dust fell. Tremors rocked the base as though the very earth were collapsing. Chunks of stone tumbled to the floor.

"Break."
