Flying Thunder God, Fate Is Unavoidable

In that gloomy river valley, the atmosphere was oppressive and heavy, as if the very air had been stained a shade of gray. This place would become the stage for the final decisive battle between the two clans, a life-or-death struggle about to unfold.

The sounds of battle cries rang through the heavens like a thunderous roar, shaking the soul of every person present. Warriors brandished their weapons, charging forward with courage, rushing toward the enemy without a hint of fear. Their shouts revealed a desperate thirst for victory and a fearless defiance of death.

The explosive sounds of ninjutsu erupted one after another, blooming like fireworks in the night sky—brilliant and lethal. Various techniques intertwined and collided in the air, releasing immense energy and triggering wave after wave of shockwaves. Fire, lightning, and storms—these powerful elements raged through the valley, dragging everything in the vicinity into a vortex of destruction.

The agonizing screams of the dying echoed across the battlefield, the final struggles and desperate cries of life. Each shriek was bone-chilling, as if one could feel the approach of death itself. Blood stained the earth red, and corpses lay scattered across the valley in a gruesome, unbearable sight.

All of this intertwined to compose a cruel symphony of war. Every note was the fading of a life, every beat the arrival of death. Within this bloody melody, the warriors of both clans wrote their own chapters with their lives.

The arrival of Uchiha Madara, with his immense strength and intimidating presence, temporarily stabilized the Uchiha lines. Though wounded, his fighting style remained wild and violent; wielding his Gunbai and Kama, he manipulated his Tengu-form Susanoo to clash fiercely with the massive Wood Dragon and the Flowering Tree Forest controlled by Hashirama Senju. Every collision caused the earth to tremble and shockwaves to roll. His very existence was the banner of the Uchiha clan.

Meanwhile, Izuna Uchiha was like a vengeful ghost, his target singular: Tobirama Senju. His Mangekyo Sharingan vision was already blurring, but relying on his superior swordsmanship, his familiarity with Tobirama's tactics, and a ferocity that bordered on mutual destruction, he clung tightly to his opponent. Every one of his attacks was delivered with full force, fire and blade-light weaving together, forcing Tobirama to constantly use the Flying Thunder God technique to maneuver, unable to easily break away to support others or cast forbidden arts.

"Tobirama! Today I will take your life to sacrifice to the souls of my kin!" Izuna's voice was hoarse from Chakra exhaustion, yet carried a venomous hatred.

Tobirama Senju's expression was cold and stern; the Flying Thunder God technique made him as elusive as a teleporting phantom, and his Water Style ninjutsu was cunning and ruthless. He did not engage Izuna head-on, but instead used speed and tactics to circle him, seemingly waiting for something. His gaze occasionally swept toward his brother's battle in the center of the field, only to quickly retract, calmly analyzing every move Izuna made.

"Your eyes are reaching their limit, aren't they, Izuna?" Tobirama's cold voice came through the roar of a water dragon, attempting to use words to disrupt him.

"It is enough to take your head!" Izuna roared, the flames on his blade burning more intensely as his offensive surged like a tide.

On the other side of the battlefield, Uchiha Sou fought desperately, yet most of his focus remained tethered to the duel between Izuna and Tobirama. His sense of "inward seeking" could clearly perceive that Izuna's life force was like an overdrawn oil lamp, burning frantically and unstably, the sense of "discord" within it growing heavier. Tobirama, however, was like cold, hard iron, his aura steady, waiting for the moment of that fatal strike.

Suddenly, the battle between Madara and Hashirama reached a fever pitch. A fierce tail-swipe from the Wood Dragon caused Madara's old wounds to flare, and his movements faltered for a split second!

It was that very instant!

The opportunity Tobirama Senju had been waiting for appeared! He deliberately used a Water Clone to take a fierce blow from Izuna, while his true self used the cover of the explosion and the Water Body Flicker technique to gain distance, his hands forming seals with unprecedented speed!

"Flying Thunder God Slash!"

His figure vanished from the spot instantly—not to attack directly, but to appear beside a special Kunai that had been quietly placed in the shadow of a boulder in Izuna's blind spot!

The timing and the angle were exquisite to the extreme! It was exactly when Izuna's old strength was spent and his new strength had yet to arise, and his mind was momentarily distracted by the crisis on Madara's side! It was also the area his failing Mangekyo vision could least account for!

Izuna's combat instincts allowed him to perceive the extreme danger; he twisted his body to the limit, his Sharingan spinning frantically in an attempt to track the movement!

But, it was too late.

Shhh--!

A cold, chilling light, surpassing the limits of visual perception, passed by with the precision of a death god's kiss!

Izuna's body stiffened violently, and the blade in his hand clattered to the ground. He looked down in disbelief to see a terrifying, massive wound carved from his chest to his abdomen; blood gushed out like a broken levee, instantly staining his armor and the earth beneath him.

"Urgh..." He wanted to say something, but only blood welled from his mouth; his vision darkened rapidly, and his strength receded like a retreating tide.

"It's over." Tobirama's figure appeared not far away, his voice as cold as ever, devoid of any emotional fluctuation. He glanced at the rapidly weakening Izuna and did not deliver a finishing blow, instead looking vigilantly toward Uchiha Madara, who was charging over frantically in the distance. For him, the objective had been achieved; this fatal wound was beyond saving.

"Izuna!!!"

Uchiha Madara let out a heart-wrenching roar, completely ignoring Hashirama's Wood Dragon, and rushed toward the spot where his brother had fallen like a madman. His massive Chakra erupted uncontrollably due to his rage, repelling everything in his path.

He reached Izuna's side and scooped up his brother's limp body. Looking at the ghastly wound and Izuna's eyes, which were rapidly losing their luster, Madara's body trembled violently from immense grief and fury.

"Bro...ther..." Izuna used his final ounce of strength, his lips moving as if to leave a final request, but in the end, his hand fell limply, and the Mangekyo light in his eyes extinguished completely.

"Izuna! Izuna!!!" Madara held his brother's still-warm corpse tightly, letting out a piercing, mournful wail toward the heavens as tears of blood slid from his eyes. Madara's aura surged even more majestically, blood spilling from the corner of his mouth as his crazed eyes locked onto Tobirama: "I will owe you your life for now; one day, I will take your head for Izuna, to offer as a sacrifice to him!"

Hashirama Senju ceased his attack, watching this scene with a face full of complex, unspeakable pity and pain. Tobirama retreated quietly to his brother's side, his expression remaining calm.

The Uchiha warriors witnessed this, and their morale collapsed instantly.

"Retreat! Protect the Clan Head! Retreat!" the high-ranking members shrieked hoarsely, and the surviving Uchiha ninja shielded Madara, who held Izuna's corpse as if he had lost his own soul, and fled in a panic toward their clan lands.

The Senju clan did not pursue deeply; Hashirama raised a hand to stop his subordinates. The price of winning this war was too heavy.

Uchiha Sou followed the retreating ranks, looking back at the battlefield one last time. He saw Madara like a wounded beast, clutching his brother's corpse, his back filled with an aura of endless desolation and destruction.

That kiss of the Flying Thunder God had completely rewritten the future of the Uchiha.
