Susanoo!

The blade had an eerie crimson hue, as if it had drawn all the coldness from the endless night, radiating a chilling, bone-piercing luster.

In this tranquil atmosphere, where you could almost hear your heartbeat, the Kunai glided silently, like a venomous snake lurking in the darkness, suddenly tearing through the obstacle that blocked its path, revealing its bloody, tender flesh.

Shizune, her body trembled involuntarily, every nerve losing control under the impact of the pain.

She unconsciously let out a low groan, the sound small but filled with unspeakable pain.

Scorpion expressionlessly and slowly pulled the blade from his chest, showing no sign of panic despite his injury.

Instead of rushing to stop the gushing blood, he focused intently on examining the depths of the wound, like a seasoned doctor.

Although medical Chakra had covered the wound like a thin veil, blood still gushed out like a burst dam.

In an instant, the wound that had just endured a brutal attack was engulfed by a shocking crimson of blood.

Kakuzu stood aside, coldly watching everything unfold before him.

With his undeniably professional perspective, he coldly analyzed, "This heart has reached its end; there is no possibility of survival."

After saying this, he gently shook his head, pondering to himself that even someone as skilled in medicine as himself was powerless to save this life that was about to end. How could this scorpion, who was still somewhat naive in his eyes, possibly defy fate and change this predetermined ending?

These words brought a chilling end to Shizune's tragic fate.

At this moment, Sasori's brows were tightly furrowed, in stark contrast to Kakuzu, Kakuzu was sitting leisurely on a stool not far away.

He appeared completely relaxed, as if the life-or-death struggle before him had nothing to do with him.

"If you had multiple hearts, this embarrassing situation wouldn't happen," Kakuzu said with a hint of mockery.

Sasori focused his Chakra on Shizune's chest, trying to stabilize her injuries.

Then, he resolutely got up and walked towards Kakuzu.

Kakuzu watched him warily, his eyes full of suspicion.

"What are you going to do?" The voice was filled with tension.

"You must have many hearts! Give me one of yours!" Scorpion's voice was resolute and decisive.

Kakuzu first narrowed his eyes in confusion, then widened them in shock. "Absolutely impossible!"

He immediately stood up and fled, shouting, "You would never lay a finger on my heart!"

When it comes to the heart, Kakuzu's emotions are far more agitated than money.

After all, his heart is the source of his life in this cruel world, the very foundation upon which he depends for survival.

Kakuzu knew in his heart that the heart of Hanzo of the Salamander, whom he had just defeated, was one of the strongest in the entire Shinobi World.

How could he possibly give away such a precious heart so easily?

He worked in a dangerous profession, his life hanging by a thread, facing the threat of death at any moment.

When other hearts fail, Kakuzu may need this heart to prolong his life at any time.

"Give it to me." Scorpion made his demand again with unwavering conviction; he had promised Koki and he had to keep his word.

Kakuzu flatly refused. "Don't even think about it!"

In his view, he would only donate his heart if his boss's life was threatened, but he would never agree to donate it to this stranger.

Scorpion was filled with anxiety; must they really have to resort to force?

This is taking way too much time.

His gaze was fixed on Kakuzu, his mind rapidly calculating all the possibilities.

At that moment, Tsunade listened to Shizune's increasingly faint breathing, her heart felt as if it were being gripped tightly by an invisible hand.

Without hesitation, she knelt down beside Shizune. Shizune might have been just a part of her memories before, but now, Shizune had become an indispensable part of her life.

A faint green light emanated from Tsunade; it was her unique Medical Ninjutsu — the Mystical Palm Technique.

Despite the blood staining her body, Tsunade's body trembled slightly, but her hands remained steady as she gently covered Shizune's wounds.

As the Mystical Palm Technique was performed, the blood flow seemed to slow down.

Koki's gaze was fierce, his anger directed at Danzo's fearlessness. The dart-shaped Mangekyou Mangekyō Sharingan in his eyes spun rapidly, and drops of blood silently slid down his cheek, tracing a breathtaking path.

The azure waves of Chakra surged irresistibly, breaking through the shackles of the Cursed Seal and bursting forth from the body.

The surrounding air seemed to be impacted, resonating with subtle vibrations.

In the blink of an eye, the arm of a god-like being, holding an indestructible shield, stood before Koki, its chilling aura sending shivers down one's spine.

A roar and a hiss intertwined, a gale and flames erupted in an instant, and the shockwave made the earth tremble.

At this moment, the scene was completely silent, all eyes were drawn to that towering arm, and everyone was filled with shock and bewilderment.

Whether it was Danzo, Orochimaru, or even Tsunade was treating Shizune, as well as Sasori and Kakuzu, Danzo's subordinates all stared wide-eyed at that arm.

A question simultaneously arose in their minds: What exactly is this?!

Danzo's expression changed drastically; his previous confidence was replaced by astonishment. He had never expected that Koki would possess such power.

Orochimaru's curiosity intensified, his gaze hooked as he intently stared at Koki and her arm, lost in thought.

Tsunade blurted out, "Susanoo?! How is that possible?"

The Senju Clan had extensive knowledge of the Uchiha's abilities, Tsunade immediately recognized the extraordinary nature of this power.

Susanoo, the ultimate power contained within the Mangekyō Sharingan, materializes Chakra, forging a mighty war god, combining offense and defense, representing the pinnacle of Dōjutsu.

It evolves and grows as the user's pupil power increases; only those with symmetrical Mangekyō Sharingan can wield it, and its color and weapon vary depending on the user.

Susanoo symbolizes destructive power; legend has it that anyone who sees it will die.

Danzo's subordinates were panicked and at a loss, completely bewildered by such power.

All eyes Koki, in disbelief that the Uchiha Clan could produce such a young genius.

Koki already awakened the Mangekyō Sharingan? That mysterious and powerful force made everyone present feel an unprecedented sense of oppression.

"Susanoo!" Koki narrowed his eyes slightly and murmured these four words softly. His voice was as clear and ethereal as the faint blue starlight under the night sky, echoing in the air.

In an instant, a powerful and terrifying Chakra surged wildly and continuously from his body.

As this immense and unparalleled power erupted, the surrounding space seemed to be kneaded by an invisible giant hand. The originally calm air began to twist and deform violently, just like a mirror that had been struck hard and shattered.

Then, under the horrified gazes of the crowd, an enormous, semi-transparent skeleton silently descended upon this world.

This skeleton was tens of meters tall, exuding a chilling and terrifying aura, as if it did not come from the human world, but was a peerless demon god slowly emerging from the gloomy and terrifying underworld.

The supreme majesty and profound fear emanating from the demon god are enough to paralyze ordinary people to the ground with just a glance, robbing them of all courage to resist.

The matter did not end there.

Suddenly, the previously still Chakra seemed to be summoned by some mysterious force, and began to swirl rapidly around the skeleton like a violent storm.

At the same time, the skeleton was growing rapidly at a speed imperceptible to the naked eye, with muscles, flesh, and intricate meridians spreading and covering it at an astonishing rate.

In just a few breaths, the skeleton, which was originally just a skeletal frame, was now draped in a magnificent battle suit made of pure Chakra, transforming into a valiant and majestic giant warrior standing two stories tall.

This warrior had a strong and upright physique, with every muscle line exuding explosive power, and he emanated an aura of inviolability.

Just then, the imposing samurai suddenly raised his right arm and held the enormous longsword formed from Chakra high in his hand.

As he made this move, a deafening howl of wind suddenly arose, the sound of which, like the roar of a dragon and the howl of a tiger, resounded through the sky, making people's eardrums ache.
