Defecting Ninja

Northern Territory, Nameless Canyon. The howling blizzard seemed intent on burying every trace of existence in the world.

Led by Kakashi Hatake, the elite Konoha squad finally arrived at this bloody patch of land at the edge of the world, following the faint, desperate distress signal sent by Nadeshiko Haku and the lingering, heart-stopping remnants of chakra.

The scene that met their eyes sent a chill through even these battle-hardened ninja.

The massive underground entrance had long since collapsed, leaving the interior structure in utter ruin. The walls, the floor, and even the ceiling were covered in bizarre signs of destruction—not from explosions or blades, but as if they had been pulverized by countless invisible, gargantuan fists striking with absolute, raw violence! Corpses were embedded into the rock face in cruel fashion or reduced to unrecognizable smears of gore on the floor, the heavy scent of blood mingling with the icy cold to create a nauseating stench.

"What... what kind of power could have caused this?" an Anbu member asked, their voice raspy, their face beneath the mask filled with horror.

Kakashi did not answer. His single eye swept sharply across the battlefield, his brow furrowed tight. He had never seen or heard of such a method of destruction; it was the manifestation of pure, extreme "force"—cold and brutal. The unease in his heart grew like wild vines.

"Search! Find any survivors! Quickly!" Kakashi suppressed his anxiety and issued a sharp command.

The team members scattered, cautiously entering the hellish ruins.

Soon, in a relatively intact corner that seemed to have been deliberately shielded, they found their target.

Nadeshiko Haku lay unconscious against the rock wall, her face pale as paper. Her breathing was shallow, but her vital signs remained stable. There were abrasions on her forehead and dust covered her clothes, but the most striking detail was the precise, clean strike mark on the back of her neck—clearly the cause of her unconsciousness.

And there, on the cold stone just a short distance in front of her, lay a Konoha forehead protector.

Everyone's gaze froze.

Across that forehead protector, someone had used a kunai, or perhaps something even sharper, to carve a long, shocking horizontal line—deep and resolute!

Missing-nin!

The symbol struck everyone's heart like the coldest of verdicts.

Kakashi slowly knelt, his fingers trembling as he picked up the protector. The cold metal stung his fingertips, but it stung his heart even more. He could feel the overwhelming rage, despair, and total detachment contained within those scratches. Had the child he watched grow up, the one he tried to guide toward the light, finally been swallowed by the darkness?

"Miss Haku!" A medical ninja immediately stepped forward to perform an emergency examination and treatment.

"Report! No other survivors found! All Root members... confirmed dead!" another team member reported, their voice heavy with suppressed shock.

Kakashi gripped the cold forehead protector tightly, his single eye filled with unprecedented gravity and pain. He stood up, his voice hoarse and heavy: "Send Haku back to Konoha immediately for full treatment! Seal the site and collect every clue you can find! Do not miss a single detail!"

Konoha, Hokage Office.

The atmosphere was so oppressive it was hard to breathe. Naruto Uzumaki stood by the window, his back looking unusually heavy. Inside the office, the urgently summoned Hatake Lian, Shikano Nara, Chiba Akimichi, Kazamatsuri Yamanaka, and Himawari Uzumaki—who still wore a look of worry—all held their breath in anticipation.

The door pushed open and Kakashi walked in, his face grim. He placed the scratched forehead protector gently onto Naruto's desk.

That horizontal line seemed to tear through the facade of peace, causing everyone's heart to tighten instantly.

Naruto turned around, his heavy gaze sweeping over the group, especially Lian, whose face had turned deathly pale. He took a deep breath, his voice low and slow, each word carrying the weight of a thousand jun:

"Kakashi-sensei and his team found Haku at the Root stronghold in the Northern Territory... She was injured, but her life is not in danger."

The group exhaled slightly, but their hearts remained suspended, waiting for the "but."

"However," Naruto's voice became even more strained, "the stronghold was completely destroyed, and all Root members were wiped out. At the scene... only this was found."

His gaze fell upon the forehead protector.

"Based on the traces at the scene and Haku's condition... Shuoyue did this alone. Then, he knocked Haku unconscious and left this behind..."

Naruto closed his eyes, then opened them again, filled with pain and disbelief, yet forced to announce the cruel truth:

"He... has defected."

The word "defected" struck like a thunderclap, leaving everyone dizzy and stunned!

"Impossible!" Chiba Akimichi was the first to cry out, his chubby face filled with shock and denial. "How could Shuoyue..." "Is there a mistake? Maybe it was an enemy..." Kazamatsuri Yamanaka argued eagerly, though his words sounded weak and hollow. Shikano Nara's usual laziness had vanished; he stared fixedly at the forehead protector, his brain racing to connect all the clues—Shuoyue's long-standing hatred, his distant attitude toward Konoha, that terrifying power... In the end, he could only let out a helpless sigh and close his eyes in pain. Himawari covered her mouth, her blue eyes instantly blurred with tears. Looking at the forehead protector, she seemed to see the cold, resolute gaze of her brother Shuoyue, and her heart ached so much she couldn't breathe.

And Hatake Lian...

He stared blankly at the forehead protector on the table, his mind a void. Brother... defected? The word was like the sharpest kunai, instantly piercing all his defenses.

The brother who, though taciturn, would silently shield him from all danger and stand guard at his door when he had nightmares... The brother who had promised to protect him forever... Had abandoned Konoha? Had abandoned... him?

Why? What happened?!

The immense shock, confusion, fear, and the heart-wrenching pain of being utterly abandoned by his closest kin washed over him like a tsunami!

"Bro... brother..." he muttered to himself, his body beginning to tremble uncontrollably, his black eyes filled with extreme chaos and collapse.

Violent emotions surged through his nerves and eyes like a broken dam!

A searing heat accompanied by intense pain erupted from deep within his eyes!

The next moment, deep within his violently trembling, tear-filled eyes, three black tomoe suddenly emerged and began to spin with unprecedented speed!

Three-Tomoe Sharingan, activated!

Powerful ocular energy spilled out uncontrollably, carrying the boy's shattered grief and despair.

"Lian!" Naruto exclaimed, appearing instantly by Lian's side to support him as he nearly collapsed.

Lian gasped for air, his Three-Tomoe Sharingan fixed on the forehead protector, tears mixed with tiny traces of blood from the awakening sliding down his cheeks. He could not accept this reality; the entire world turned blood-red before his eyes, his brother's departing figure and that cold forehead protector intertwining repeatedly, nearly driving him to madness.

Meanwhile, deep within a forgotten, ancient shrine filled with serene natural energy far from Konoha.

A ripple stirred in the space, and a figure slowly emerged.

He wore a pristine white hunting robe, a black haori draped over it, and a spiral-patterned white mask that revealed only his right eye—the very attire Uchiha Obito had grown accustomed to. After experiencing the vicissitudes of life and returning from his atonement, he had chosen to stay far from the world, guarding this once-sacred land.

He watched the youth who had suddenly appeared in the center of the shrine, radiating a bone-chilling cold and an unfamiliar, immense ocular power, his brows knitting slightly beneath his mask. He could sense the thick, inseparable hatred and despair clinging to Shuoyue.

"You have returned." Obito's voice drifted through the mask, calm yet carrying a trace of imperceptible concern. "It seems that, in the end, you have touched that cold 'truth' after all."

Shuoyue slowly raised his head, his eyes—weeping blood, patterned with complex and demonic designs, and certainly not ordinary Sharingan—meeting Obito's gaze directly. His voice was cold, devoid of a single shred of human emotion, as if it had risen from the abyss:

"The high command of Konoha... tacitly approved the actions of 'Root'... tacitly approved the purge of the Uchiha..."

Obito was silent for a moment, then sighed softly, his voice tinged with deep helplessness and pity: "The shadows of history are always long and heavy. Where there is light, darkness must coexist. This is the cruelty of reality... you have finally seen it with your own eyes."

Shuoyue did not respond; the chill radiating from his body only intensified. He slowly raised his hand, staring at these newborn eyes that brought him endless pain and power.

"These eyes... are strange." He spoke coldly, as if evaluating a foreign weapon. "They tell me... they are called the 'Eighty Gods Mirror'."

"'Eighty Gods Mirror'?" Obito tilted his head slightly; he had never heard this name before.

The patterns in Shuoyue's Mangekyo shifted slightly, emitting an even more eerie and profound light, as if an invisible mirror were truly floating within them.

"But its true power is not to reflect physical forms..." Shuoyue's voice remained flat, yet he revealed a secret capable of shaking the very foundations of the ninja world. "It can... reflect and analyze the 'origin' and 'structure' of all ocular techniques and ninjutsu."

"As long as I see it, as long as I understand the principles behind its operation..." "Then, all ocular techniques and all ninjutsu in this world..." "Can be reflected by it, can be... copied and controlled by me."

The "Eighty Gods Mirror"—its essence was the embodiment of ultimate insight, comprehension, and simulation! It was not a simple copy, but a fundamental understanding of a technique's composition, allowing for its perfect reproduction, or even... deduction and optimization!

Obito's pupils contracted sharply beneath his mask; even with his current level of experience and insight, he felt a profound shock! To copy all the ocular techniques and ninjutsu in the world? What kind of heaven-defying, inconceivable power was this?! The very existence of these eyes was a subversion of the existing ninjutsu system!

He understood in an instant why Shuoyue had become this way. Possessing such power, while burdened by such a blood feud and cruel truth, this child's heart had likely been completely eroded by darkness.

Shuoyue's cold gaze pierced through his Mangekyo at Obito, his eyes no longer bearing any trace of the past, leaving only a thirst for power and a fixation on vengeance:

"Tell me more... the truth of Konoha's shadows, the dark rules by which this world operates... I need to know everything."

He had completely severed his bonds with Konoha, casting aside the past. Now, he was merely a blade tempered by hatred, yearning to cut through all mist and hypocrisy. And the man before him, who had experienced the deepest darkness and ultimately chosen a different path, was undoubtedly the "key" and the validation of power he needed most at this moment.

In the quiet shrine, the two generations of Mangekyo Sharingan wielders stood in silent opposition. On one side was the White Crow, who had endured hardships and chosen to protect and atone; on the other was the Young Eagle, burdened with a blood feud, clutching forbidden power, and resolutely stepping into the darkness.

The air seemed to solidify, leaving only the rustling of wind through the leaves outside the window, and the cold, dangerous light faintly emanating from the invisible "mirror" within Shuoyue's eyes.
