Kakashi-Five elements

"Damn you, you little yellow-haired brat! Don't you ever run out of chakra?" An Lushan roared in fury, his rage surging like a volcano about to erupt. "Come on, keep pushing! Let's see how long you can last!"

He was truly at his wit's end.

This relentless, infuriating boy had chased him all the way from the future and refused to give up. Now, they stood face-to-face in the heart of battle, a clash between sheer determination and overwhelming power.

"Since you won't back down... then DIE!"

Naruto's eyes widened in alarm as he sensed the sudden spike of chakra. A violent purple glow began condensing at the cannon embedded in An Lushan's mouth.

In an instant, a massive energy sphere several meters wide launched toward Naruto, tearing through the air like a meteor!

Naruto immediately jumped back, trying to retreat beyond the blast range.

BOOM!

The purple sphere exploded upon impact with the ground, creating a thunderous shockwave that made the earth quake and tremble!

Though Naruto managed to dodge the direct hit, the ripple effect of the blast surged outward in all directions like a tidal wave of destruction.

He was exhausted, his chakra nearly depleted, and couldn't move fast enough to escape the aftermath.

Swish!

Just when the energy wave was about to engulf him, a yellow flash streaked through the air.

Minato Namikaze appeared in front of Naruto and instantly teleported him away from danger.

"Are you alright, Naruto?" Minato asked urgently, gently placing his son's arm over his shoulder to support him.

"Yeah... I'm okay, Dad," Naruto replied, forcing a smile despite his fatigue. "I just used up too much chakra, that's all."

Even in such a critical moment, Naruto's bright grin returned. His optimistic spirit shone through, and he met his father's eyes with unwavering resolve.

Minato smiled back warmly. "You're truly my son."

Then, with a more serious expression, he turned to face Naruto directly.

"Alright then, hold out your right hand. Use the Rasengan—I'll assist you."

"Huh? Oh, okay!"

Though surprised, Naruto didn't hesitate. He stretched out his right hand obediently.

Minato swiftly rubbed his hands together and pressed them into Naruto's palm. In seconds, a familiar blue Rasengan swirled into existence in Naruto's hand.

Then, Minato conjured a Rasengan of his own—equal in size and intensity. As he slowly opened his palms, the Rasengan began to expand, glowing brighter with each passing second.

To Naruto's amazement, the Rasengan in his own hand began reacting, resonating with his father's chakra. It grew larger, pulsing with vibrant energy.

"Dad... what's happening?" Naruto asked, stunned.

Minato's voice was calm and confident. "When chakras with similar properties come into contact, they resonate. When combined, they create something even stronger."

"And now, when our Rasengans merge... you'll wield the strongest Rasengan ever created!"

A spark of excitement lit up Minato's eyes. This was the moment he had dreamed of—fighting alongside his son and combining their strength.

As the swirling Rasengans expanded further, Minato pushed his own forward.

Boom!

The two energy spheres collided, instantly fusing into a powerful new form. A glowing storm of green and blue chakra spiraled outward in a raging vortex, enveloping Naruto like a divine cloak.

The newly formed jutsu roared like a storm.

Naruto, caught within the tornado of chakra, stared in disbelief.

"W-What is this?!"

Minato raised the combined Rasengan high above Naruto's head. "This is the strongest—the Taichi Rasengan!"

An Lushan, observing from a distance, was dumbfounded. "What kind of sorcery is this?!"

Even he could sense the immense destructive power emanating from the strange new technique. It was unlike anything he had seen before.

Still, he wasn't afraid. His regeneration ability was practically limitless. Even if he was shattered into pieces, he would simply reassemble.

"I'll just trade injuries for injuries again. This won't be the first time I've died!"

He clenched his fists. "If you're so stubborn, then I'll completely annihilate you!"

Suddenly, dark purple energy began crackling above the central tower. Arcs of black lightning struck An Lushan's towering, monstrous body, supercharging him with a terrifying glow.

His massive form—over a hundred meters tall—began pulsating with raw energy.

He had entered an overclocked state.

"This time, I'll show you my strongest attack!"

From deep within his abdomen, an enormous cannon began glowing. It had never been used before—this was his final trump card.

"Dragon Vein Super Dragon Fire Technique!"

The beam began to charge.

But just before the devastating attack was released, Minato and Naruto vanished from sight once again.

"What!?"

An Lushan turned his head and saw Minato leap into the air, leaving the Taichi Rasengan in Naruto's hands.

Minato's eyes flashed. "Shuriken Shadow Clone Technique!"

Dozens of glowing green shuriken flew toward An Lushan, splitting into hundreds midair.

BOOM! BOOM! BOOM!

Each one pierced An Lushan's massive chest and exploded, staggering him.

At the same time, deep within the central tower, Sarah reached the altar of the Dragon Vein and used a forbidden sealing technique to cut off its energy supply.

"Heh... it's all meaningless," An Lushan scoffed.

"High-Speed Regeneration Technique!"

He expected the wounds on his chest to heal in seconds.

But three seconds passed—and nothing happened.

A wave of confusion and panic washed over him.

"What... what's going on?"

His expression twisted in rage. "Sarah!!"

Back on the battlefield, Minato gave the signal. "Now, Naruto!"

"I'm on it!"

Naruto roared with spirit and charged forward, raising the Taichi Rasengan high.

"Urrrrrrraaaaaahhh!"

Enraged, An Lushan launched a desperate counterattack.

Thousands of kunai burst from his arms, flying toward Naruto like a steel storm.

But the spinning chakra tornado surrounding Naruto easily deflected them all.

"You won't get me that easily!"

Naruto leapt into the air just as An Lushan prepared his final blast.

"Dragon Vein Super Dragon Fire Technique!!!"

A colossal purple beam of destruction surged toward Naruto.

"Taichi Rasengan!!!"

With a battle cry, Naruto plunged into the beam.

BOOM!

The Rasengan tornado met the energy beam head-on—and completely shattered it within a second!

An Lushan screamed in frustration. "No! You brat!"

In a final desperate move, he threw a massive punch.

But it was futile.

Naruto's Rasengan pierced through An Lushan like a divine spear, tearing through his puppet shell as if it were paper.

"W-What?!"

"Aaaaaarghhhh!!"

The spinning energy core blasted through An Lushan's chest, obliterating his heart.

He howled in anguish and defeat.

"Konoha... this world... was supposed to belong to me!"

"But you people ruin everything! Over and over again!"

"I won't die like this... I'll destroy the Dragon Vein myself!"

With the last of his strength, An Lushan staggered away, dragging his shattered body toward the central chamber of the Dragon Vein.

Inside, a massive pit pulsed with thick, swirling dragon energy. At its center stood an altar, carved with goddess statues and ancient runes. Only a narrow stone bridge connected the entrance to the altar.

Sarah stood at the center of the altar—right where the energy flow was controlled.

An Lushan looked at her one last time.

Then, without hesitation, he threw himself into the pit and self-destructed.

BOOOOOOM!!!

The explosion was catastrophic.

Energy surged out of control. The once-stable Dragon Vein began to go berserk, releasing torrents of chakra like a ruptured dam.

Minato rushed to the edge of the pit, alarmed.

"The Dragon Vein is destabilizing!"

Suddenly, the altar beneath Sarah began cracking.

"No!" she gasped, turning to flee.

But the stone bridge crumbled under her feet after only two steps.

With no time to react, Sarah plummeted into the abyss below.
