Konoha: Superman template, the spoiled brat becomes strong.

However, when Sasuke was knocked away by the Phantom Slash using Chidori Stream, the green vine thrown by the girl happened to entangle the ninja tool pouch at his companion's waist.

Then! The bronze dagger she swung gleamed coldly between Naruto's fingers, and the moment the blade grazed Phantom's ear, the groove in her breastplate suddenly resonated.

The scalding heat of the Spirit Pearl suddenly penetrated his clothes. Naruto performed a backflip and landed diagonally behind the crystal flower bud, discovering that the stamen of the demon flower had the same pattern as the Spirit Pearl.

Sasuke wiped the blood from his lips and suddenly shouted: "Chakra attacks will feed back to it!" His Sharingan caught the slight expansion of the armor as the phantom absorbed the Wind Release shuriken. He swung out a steel wire to wrap around Naruto's wrist as he was about to form hand seals, using taijutsu!

Naruto spun around and kicked the crack in the phantom's left shoulder armor. The sound of metal shattering and the burst of purple crystal powder blinded him.

The vines the girl flung out seized the opportunity to wrap around the phantom's ankle, while Sasuke glided along the ground and threw three shuriken that precisely pierced the joint gaps of the armor-like energy body.

Within the encirclement formed by the three alternating attacks, the magatama on Phantom's chest began to flicker.

Now! As Naruto flipped over the phantom's head, he glimpsed the bronze key floating inside the crystal bud resonating and vibrating with the spirit orb.

He held the bronze dagger upside down and thrust it toward the phantom's nape, but as the tip of the dagger touched the armor, he felt a sudden burst of heat from the spirit orb—it was clearly a tremor from encountering something of the same origin.

The moment the key detached from the flower bud, the sound of war drums from the Warring States period suddenly resounded throughout the cave.

Naruto's right hand, which was gripping the key, trembled uncontrollably as the scalding energy of the Spirit Orb surged through his meridians to his heart.

The last thing he saw was Sasuke's Sharingan wide open in astonishment, and the beauty mark under the girl's eye illuminated by purple light as she lunged at him.

The moment Naruto's fingertips touched the key, the entire cave suddenly became eerily silent.

The patterns on the surface of the bronze key seemed to come alive, drilling into the meridians along his fingertips.

Kurama's shrieking cries within the sealed space abruptly ceased, and crimson chakra uncontrollably seeped from his pores, forming a semi-transparent vortex around the boy.

This power... Sasuke's Sharingan spun wildly, the three tomoe almost forming a new pattern.

He saw dark gold sealing runes appear on the back of Naruto's neck, perfectly matching the patterns on the key's surface.

The mysterious girl suddenly covered her mouth and took two steps back. The gray-white vines on her wrist suddenly grew wildly into green vines, uncontrollably wrapping around Naruto's ankles.

The instant the key completely detached from the crystal bud, the warrior phantom suddenly turned into amethyst powder and collapsed with a crash.

Tens of thousands of crystal dust particles condensed in the air into the phantom image of a war flag from the Warring States period, and then dissipated with the sunlight seeping down from the cave ceiling.

Naruto staggered and knelt on one knee, the purple liquid dripping from the tip of the key etching a snake-shaped dent in the ground.

Watch out! Sasuke's kunai suddenly pierced Naruto's ear, severing a strand of hair that had been corroded and turned purple.

The mysterious girl's vines contracted rapidly, suspending the key in mid-air, off the ground.

Chapter 399: Breaking the Illusion and Obtaining the Key

The instant the key completely detached from the crystal bud, the warrior phantom suddenly turned into amethyst powder and collapsed with a crash.

Tens of thousands of crystal dust particles condensed in the air into the phantom image of a war flag from the Warring States period, and then dissipated with the sunlight seeping down from the cave ceiling.

Naruto staggered and knelt on one knee, the purple liquid dripping from the tip of the key etching a serpentine dent in the ground.

Watch out! Sasuke's kunai suddenly pierced Naruto's ear, severing a strand of hair that had been corroded and turned purple.

The mysterious girl's vines contracted rapidly, suspending the key in mid-air, off the ground.

The three then noticed that a viscous black substance was seeping from the end of the key, and the dripping sizzled as it burned the ore.

Kurama's cold snort exploded in Naruto's mind: "He actually forged the Dragon Vein Crystal into a key, no wonder it could activate my power." The giant beast behind the sealed iron bars suddenly opened its right eye, its crimson-gold vertical pupil reflecting the dark patterns flowing on the key's surface. "Kid, this thing is absorbing your life force."

Naruto wiped the blood from his nose and was about to speak when Sasuke suddenly grabbed him by the collar and dragged him away from where he stood.

Where they had originally stood, three poisoned shurikens were deeply embedded in the rock wall.

Granny Chiyo's puppet bird swooped down from the crack in the cave ceiling, the poisonous wind whipped up by its wings making it impossible for people to open their eyes.

The Sand Village's puppet technique? As Sasuke's Lightning Blade shattered the second wave of hidden weapons, he discovered a mysterious girl weaving a barrier with vines.

The totem on her wrist had turned into the same dark gold as the key, and the vines would develop strange purple spots every time they came into contact with the poisonous fog.

Nine-Lama suddenly burst into laughter in the sealed space: So that's how it is!

The little girl is... The giant beast's words were interrupted by a sudden, intense pain as the spirit orb on Naruto's chest began to draw Nine-Tails chakra in reverse.

Suddenly, the key broke free from the vines and pierced straight towards Naruto's heart.

"Don't touch it!" The girl's exclamation and Sasuke's lightning release arrived at the same time.

The moment the electric net formed by the Thousand Birds Stream enveloped the key, the magatama pattern of the Sage of Six Paths suddenly appeared on the surface of the spirit orb.

The floating key trembled like a mournful cry before finally settling quietly into the girl's trembling palm.

When the three finally emerged from the cave, the setting sun had dyed the clouds the color of blood clots.

Naruto touched the still-burning mark on his chest and noticed that the key had become unusually docile in the girl's hand.

She was wrapping vines around the end of the key, the dark gold patterns and green vines intertwining to form a new sealing spell.

Thirty miles to the southeast. Sasuke suddenly stared at the darkening sky, sensing the second key. The phantom image of the key swirled in his Sharingan, and fragments of armor from the Warring States period were reassembling into a map within his pupils.

Suddenly, the girl pressed the key into Naruto's palm, and vine patterns spread along their touching skin.

Just as Naruto was about to ask a question, he noticed tiny specks of crystalline dust floating in the afterglow of the setting sun—exactly the same amethyst powder that had erupted when they broke the illusion.

Nine Lama's warning and the sound of something cutting through the air came at the same time: Bow your head!

A crimson glow suddenly tore through the sky, and countless burning fragments of armor fell from the crack in the clouds.

As a piece of armor bearing the Uzumaki clan emblem grazed Naruto's cheek, the vines on the girl's wrist suddenly straightened.

As she gazed at the giant, armored figure gradually taking shape in the sky, she revealed an expression of near-fear for the first time.

Sasuke's Kusanagi sword was already drawn, and lightning illuminated the frenzied excitement in his eyes.

Naruto gripped the still-hot key tightly, and the Nine-Tails' chakra uncontrollably created spiderweb-like cracks under his feet.

Just as the last ray of sunlight disappeared, he heard the sound of horns from the Warring States period coming from deep within the clouds.

Chapter 400: A Collection of Resentment

The crimson sunset was sliced ​​into scattered spots of light by the burning fragments of armor, and Naruto's Rasengan blasted three pieces of the falling breastplate into dust.

The Nine-Tails' chakra steamed out in crimson waves on his skin, but he felt the vine totem left by the girl between his fingers burning painfully—the key engraved with the Uzumaki clan's emblem was throbbing in his palm, as if trying to break free of his flesh and fly into the giant armored shadow in the sky.

Twelve o'clock! Sasuke's Kusanagi sword, wrapped in the sharp cry of Chidori, cleaved through the rain of fire, lightning reflecting the taut lines of his jaw. The map showed the key was in the giant shadow's chest.

Suddenly, the mysterious girl's vines wrapped around their ankles.

As she tilted her head back, her neck arched precariously, and the jade pendant hanging from her hair jingled softly: it was the embodiment of the resentment of a Warring States puppeteer! Only then did Naruto see clearly that semi-transparent human figures were curled up among the burning fragments of armor, each distorted face emitting a silent roar.

Kurama's sneer sent shivers down Naruto's spine: "Kid, the key is resonating." Before he finished speaking, the armored giant shadow's breastplate suddenly cracked open with a vortex-like gap, and the key in Naruto's arms flew out in response.

He instinctively lunged into the air, and the instant the Nine-Tails' chakra transformed into claws and gripped the key, a blinding white light suddenly shone in the sky.

The mysterious girl's scream and Sasuke's muffled groan rang out simultaneously.

Naruto felt as if his internal organs were suddenly gripped by an invisible hand, and millions of prism-like spatial fragments exploded before his eyes.

He desperately turned his head to look and found that Sasuke was using the skeleton of Susanoo to protect the girl, and the purple energy shield made a teeth-grinding cracking sound in the distorted space.

Hold on tight! Naruto swung out chakra chains that bound the two of them.

The energy bursting from the key in his palm burned his vision, and in his daze, he saw vines growing wildly on the girl's wrist, the turquoise fluorescence intertwining with the key's golden patterns to form a cocoon of light that enveloped them.

The feeling of weightlessness intensified suddenly, and he heard the Nine-Tails' roar pierce his eardrums: Don't let the key—

The roar of collapsing space swallowed the last sound.

As Naruto felt his back hit some kind of viscous substance, and the Nine-Tails' chakra automatically enveloped his entire body, he caught a glimpse of Sasuke's Sharingan spinning rapidly, the three tomoe almost forming a windmill shape.

Countless fragments of memories suddenly flooded his mind—the battlefields of the Warring States period, the collapsing sealing array of the Whirlpool Clan's territory, and the image of a white-haired man plunging a key into his own heart.

"Are you awake?" Sasuke's bloodied hand slapped his face, the stinging sensation from the lightning chakra bringing him back to his senses.

The three were suspended in an amber-colored transparent space, with countless weapon fragments floating in the surging torrent of chakra below.

The mysterious girl's vines wove into a spherical shield, but spiderweb-like cracks had already appeared on the surface.

Just as Naruto was about to speak, the key in his pocket suddenly beeped.

The girl pressed down on his hand with such force that it hurt: It's absorbing our chakra! Blood beads were seeping from the swirling clan emblem on the key's surface, and a needle-like pain came from where the vines were wrapped around it.

Kurama's chakra flowed uncontrollably toward the key, and Naruto was horrified to discover that the tailed beast's cloak was fading.

Sasuke suddenly cut the vines wrapped around the key.

As the Kusanagi sword grazed Naruto's hand, he saw his own pale face reflected on the blade: What are you doing!

He looked around. The purple light of Susanoo illuminated Sasuke's cold smile.

Naruto followed his gaze, and his blood instantly froze—the floating weapon fragments were converging on the key, each piece wrapped in dark, resentful chakra.

The nearest fragment of the spear was less than three inches from his throat, and the brown bloodstains on the spear tip exuded a putrid smell.

Kurama's roar was filled with unprecedented anxiety: Use the sealing technique! But just as Naruto's fingers moved to form the hand seals, the key suddenly erupted with an aura that devoured everything.

The last thing he saw was the corner of Sasuke's clothes being swallowed by light as he lunged at him, and the emerald-colored curse mark that suddenly shone in the girl's eyes.

As the thick darkness washed over his mouth and nose, he heard the crisp sound of chains snapping inside his body.

A being slumbering deep within the tailed beast's chakra opened its eyes, and the scorching hot lines of the key suddenly climbed up the blood vessels to the heart, burning a vortex-shaped mark in the chest cavity.

The amber-colored space trembled violently.

Chapter 401 Chakra Rampage

Naruto's right eye's Nine-Tails vertical pupil suddenly contracted to a needle-like shape, and the vortex clan crest on his palm burst out with dazzling golden light. The scorching energy surging in his blood vessels made him instinctively spread his five fingers.

Golden-red chakra gushed out like molten iron, condensing around the three of them into a spherical shield engraved with sealing runes.

This is... Sasuke's Sharingan reflected the flowing sealing technique formula, and he barely managed to stabilize himself by plunging the Kusanagi sword into the ground.

The mysterious girl's vine shield shattered with a crack, and she stumbled and bumped into Naruto's back. Suddenly, the jade pendant on her wrist lit up with a green light that resonated with the shield.

Kurama's cold snort carried a rough, sandpaper-like quality: "The Uzumaki clan's sealing techniques haven't been completely forgotten." Naruto felt the brand on his heart frantically draining his chakra, and a metallic shriek came from outside the shield—the remnants of weapons, shrouded in resentment, were crashing against the barrier like a torrential downpour, each crack automatically filled by golden runes.

Sasuke suddenly grabbed Naruto's wrist, and his Lightning Release chakra pierced through his meridians: "Idiot, your chakra is going berserk!" Only then did Naruto realize that fine beads of blood were seeping from his skin, and the key pattern had spread all over his right arm.

The mysterious girl suddenly bit her fingertip, smearing the blood on his heart: "The clan emblem requires a human sacrifice, with mine..."

"Enough talk!" Naruto slapped their hands away, and the Nine-Tails' chakra, mixed with golden light, suddenly expanded.

Suddenly, a deafening roar, like a mountain collapsing and the earth splitting apart, came from outside the protective barrier. A black shadow, hundreds of meters tall, slowly rose from the surging torrent of chakra.

It was a monster pieced together from countless fragments of armor, with a swirling, viscous substance like asphalt gushing from the hole in its chest.

Sasuke's Susanoo skeleton instantly unfolded: the key was in its heart. Before he finished speaking, the monster's empty eye sockets suddenly glowed with a scarlet light, and the direction of gravity in the entire space began to malfunction.

As soon as Naruto leaped out of the protective barrier, he felt his feet sink as the Nine-Tails' chakra claws scraped against the monster's chest armor, sending sparks flying.

Multiple Shadow Clone Technique! Hundreds of golden figures simultaneously launched Rasengans, but were swallowed by the black vortex the moment they touched the monster.

The monster let out a deafening roar, and Naruto was suddenly pulled towards the center of the vortex by an invisible force—Sasuke's Kusanagi sword, accompanied by the sharp cry of Chidori, pierced through the air, and the shockwave generated by the collision of lightning and black mist sent both of them flying at the same time.

The mysterious girl's vines wrapped around their waists in time.

Naruto coughed up blood and got up, only to find that the key pattern had spread to his collarbone: the core must be destroyed... Kurama suddenly gave a warning growl in his mind, and the vortex on the monster's chest suddenly expanded, with countless fragments of armor pouring down like a torrential rain.

Amaterasu! Sasuke's Mangekyou Sharingan shed tears of blood, and the moment black flames exploded on the monster's body, Naruto had already taken to the air, stepping on the falling armor fragments.

Golden-red chakra condensed in his hand into a giant sword engraved with sealing characters, and the trajectory of the sword's blade left scorching spatial cracks in the air.

The moment the sword tip pierced the center of the vortex, time seemed to stand still.

Naruto saw hundreds of faces screaming in pain emerging from the gaps in the armor, and the key pattern suddenly seared a sharp pain into his chest.

The monster let out a mournful howl that was not human, and the fragments of its breastplate suddenly rolled back, turning into a metal storm that completely engulfed Naruto.

"The bottom of the class!" Sasuke's Susanoo skeleton swelled to its complete form, and the moment the purple giant bow was fully drawn, the mysterious girl suddenly pressed down on his hand seals: "Look at his chakra!" A golden light like the sun burst forth from the center of the metal storm, and a triple rotating sealing array appeared behind Naruto, with key patterns already covering half of his face.

Nine chakra tails suddenly unfurled, tearing open the vortex on the monster's chest.

The moment Naruto plunged the sealing giant sword into the core, the entire amber space began to collapse. He heard the crisp sound of chains breaking inside his body, and some ancient aura was awakening through his blood vessels.

Sasuke's complete Susanoo cleaved through the collapsing space, and the mysterious girl's vines pulled Naruto down rapidly.

When the three of them crashed heavily onto the sandy ground of the real world, Naruto noticed that the key pattern had faded to his wrist, but the burning sensation in his heart was becoming increasingly intense.

He tried to get up, supporting himself on his knees, when a metallic, metallic taste suddenly welled up in his throat.
