"Eight-Tails, I need you to lend me more power."
'This Uchiha brat is an absolute monster.'
Just from their first clash, Killer B had already made his judgment. Jie Uchiha had definitely been hiding his true strength from the start. The speed behind his last sword strike was more than twice as fast as anything he had shown before.
And those eyes. Jie's eyes were definitely not ordinary Sharingan. Whether it was the intricate pattern spinning within them or their terrifying kinetic tracking ability, they were completely different from any Uchiha he had encountered in the past.
Within B's mindscape, Gyuki fell silent. Killer B might not fully recognize those eyes, but he did.
The Mangekyo Sharingan. It was the ultimate power of the Uchiha clan, standing alongside Wood Release as the absolute greatest bane to the Tailed Beasts.
From the very beginning, Gyuki could sense an incredibly powerful and sinister aura emanating from Jie's gaze. But he never would have imagined that a boy who barely looked like a teenager could possess such ultimate power.
'Could he be the reincarnation of Madara Uchiha?' Gyuki mused. Yet, even Madara Uchiha couldn't have possessed such immense strength at this age.
'We have to defeat him,' Gyuki realized with grim certainty. 'The Mangekyo Sharingan cannot be allowed to roam the ninja world again.'
With that thought, Gyuki's chakra began flooding into Killer B's body without reservation. In an instant, the bubbling Tailed Beast Cloak on B's back grew from two tails to four. As the massive chakra continued to surge, a fifth tail gradually began to form.
Roar!
The massive influx of power gave Killer B an unparalleled high, prompting a low, guttural roar from his throat.
"This feeling... is absolutely fantastic," B muttered, savoring the raw energy coursing through his veins. A feral smirk played on his lips, though hidden beneath the dense, dark red chakra of the cloak, no one could see it.
"Hey, brat! Time to witness my true power!" Killer B shouted. "Before I'm done having my fun... you better not die!"
A hint of brutality flashed in Killer B's eyes as he stomped his foot down hard.
Instantly, the bedrock beneath him shattered. Every tree and blade of grass within a fifty-meter radius was blown away by the sheer concussive force. Propelled by the massive recoil, his body—shrouded in the dense Tailed Beast Cloak—shot toward Jie Uchiha like a cannonball.
Clang!
Killer B didn't even draw his short swords. Just the clash of his condensed chakra claws against Jie's blade produced the sharp, ringing sound of colliding steel. The impact left a massive gash on the Tailed Beast claw, but with Gyuki's chakra surging relentlessly, the tear rapidly healed.
"Bet you don't have an answer for this, brat!" Killer B laughed out loud, charging at Jie with even greater ferocity.
"Uchiha Style: Flash Cut!"
In a split second, dozens of Jie's afterimages appeared from every direction. His crimson Mangekyo Sharingan continuously tracked Killer B's position, looking for an opening.
However, Killer B completely ignored Jie's slashes. Even when the blade left a long, deep wound across his body, B relied entirely on the cloak's immense regenerative capabilities. He fought like a madman, intentionally trading injury for injury, completely disregarding his own defense.
Furthermore, as Killer B grew accustomed to the cloak's physical amplification, his speed continued to climb. Even though Jie was fast enough to leave dozens of afterimages, his evasive maneuvers were gradually becoming useless against Killer B's frenzied, wide-scale destruction.
The Mangekyo Sharingan allowed Jie to perfectly perceive B's movements, but his physical body was slowly failing to keep up with the Jinchuriki's sheer velocity.
'This speed... is getting a bit troublesome,' Jie thought.
Staring at the blood-red form of Killer B, a trace of caution entered Jie's eyes, quickly followed by a fiercely burning will to fight.
"Only by fighting the strong can I become stronger," Jie muttered. At the exact same moment, arcs of silver-white lightning began to dance wildly across his body.
"Lightning Release: Chakra Mode!"
After defeating the Kumogakure delegation, Jie had received this Nintaijutsu as a settlement reward from the System. It was an explosive technique developed by an unknown generation of Kumogakure shinobi, heavily inspired by the Tailed Beast Cloaks used by Jinchuriki.
The user utilized their mastery over lightning chakra to envelop their body in a crackling aura of electricity. Stimulated by the lightning, every cell in the user's body unleashed vastly augmented energy, granting them explosive physical power and blistering speed for a short duration. Furthermore, the lightning cloak provided a formidable layer of defense. It was a flawless burst technique that perfectly balanced offense and defense.
However, its requirements were absurdly high. First, the practitioner needed a natural affinity for lightning chakra, along with total mastery over both its shape and nature transformations. Second, they needed exquisite chakra control; they had to tame the inherently violent lightning to stimulate their cellular activity without frying themselves from the inside out. Finally, while hyper-stimulating their cells, they had to maintain the dense layer of chakra on the surface of their skin to sustain the cloak.
This string of impossibly harsh conditions was exactly why Kumogakure had classified the Nintaijutsu as a Forbidden Technique.
But for Jie, despite the immense difficulty of the technique, mastering it had been a piece of cake. Thanks to the System's direct reward integration, the technique felt like an innate ability to him—he could turn it on and off with a mere thought. As long as he didn't keep it active for extended periods, it wouldn't cause any bodily damage, leaving him with only a brief bout of fatigue once deactivated.
Now, as Jie triggered the technique, a silver-white lightning cloak fully materialized around him. Bathed in the brilliant, crackling arcs of electricity, his composed stance made him appear entirely untouchable.
It stood in stark contrast to the chaotic, blood-red savagery of Killer B's chakra.
"Acting all high and mighty at a time like this?! He's completely looking down on me!"
Enraged, twin jets of white steam blew from Killer B's nostrils as a fifth, and then a sixth tail formed simultaneously. Thick pieces of Tailed Beast bone armor began to encase his elbows and skull, making him look even more demonic.
"Die, brat!" Killer B roared. His body blurred into a streak of bloody light as he viciously lunged at Jie.
"Eighth Blade!"
At that exact moment, Jie's lightning cloak solidified entirely. A single silver arc of electricity leaped across his crimson eyes. In a fraction of a second, Jie vanished from his spot.
Boom!
Killer B's bone-crushing headbutt hit nothing but empty air, sending him crashing wildly into the forest, tearing a massive path of destruction through the trees.
