The Mysterious Seal

On the dark ground, a deep and unfathomable fissure, like a dark scar, meanders along the palace wall, embracing the entire magnificent hall.

In the center of the main hall, a circular platform stands out abruptly, attracting attention.

On the platform, a strange object lay quietly, its body entwined with countless fine, thread-like runes. These runes, centered on the object, slowly spread out, weaving a complex and infinitely mysterious array.

The rune array emitted a faint, eerie light, revealing its nature as a powerful seal, imprisoning an unknown and mysterious force.

Where Koki stood, a straight path meandered out, leading to the mysterious platform in the central area.

The path is narrow and winding, with bottomless ravines on both sides, so dark that it is impossible to see their depths at a glance.

Within this magnificent hall, only this path can lead one to that mysterious platform.

Koki's eyes were fixed on the platform. At first, it was just out of curiosity, but as time went by, a strange feeling slowly began to grow in his heart.

The feeling was like a tiny spark of electricity gently brushing across a corner of his heart, causing his heart to beat faster and tremble slightly.

He tried his best to suppress the strange feeling surging in his heart, and carefully examined his surroundings, afraid of missing any hidden dangers.

After repeatedly confirming that there was no danger or mishap in the surroundings, he slowly took a step and steadily made his way towards the platform.

The surrounding air seemed to be frozen by a mysterious force, heavy and oppressive, making Koki's senses feel somewhat suffocated.

His eyes involuntarily welled up with tears, and waves of stinging pain served as a silent warning, foreshadowing the impending agony.

Koki's expression was slightly gloomy, and the vigilance in her heart was like a taut string, instantly reaching its limit.

He stopped in his tracks, still more than ten meters away from the platform, and stood there, refusing to go any further.

A delicate ray of sunlight pierced through an unknown crack in the sky above, bringing a faint glow to the dark space.

Under the gentle caress of this ray of sunlight, Koki finally saw clearly the true form of the mysterious object on the platform.

It was a semi-circular object protruding from the platform surface, its smooth surface gleaming with an indescribable luster.

There is a closed gap in the center, like a giant, tightly closed eye, silently watching over everything, sending chills down one's spine.

Above the crevice, a unique Kunai stands silently.

The handle of the Kunai was engraved with several mysterious runes, which were quite similar to the incantations of the array below.

Clearly, both the Kunai and the array were created to seal the eye-like object.

Koki stared at the mysterious object, her mind filled with endless questions.

In his eyes, pain, like delicate silk threads, silently wove into a dense net, gradually tightening.

Incredibly, this attack didn't come on suddenly like the previous one; instead, it slowly intensified until it became unbearable.

Koki involuntarily closed his eyes, his thoughts racing like lightning. As he approached this place, the pain in his eyes followed. Was there some unspeakable connection between them, or just a meaningless coincidence?

Before they could even figure things out, a thunderous roar suddenly erupted overhead, echoing through the empty space of the hall.

Koki suddenly looked up and saw a figure falling rapidly from the entrance above her like a shooting star.

He looked closely and realized it was Naruto.

Then another person jumped down from the entrance; it was the ninja who had attacked him and Minato earlier.

Naruto staggered onto the straight path, Shuriken, a heavy Kunai clutched in his palm, and his eyes warily scanned his surroundings.

The ninja descended from the sky, caught sight of Koki's figure, and was slightly taken aback. A spark of surprise flashed in his eyes for a moment, and then he turned in mid-air, shooting towards Koki like a phantom.

Its speed was so swift, like a dazzling display of light, that it was difficult to capture.

"Watch out!" Naruto instantly ejected the sword from his mouth.

Koki frowned, silently enduring the stinging pain in his eyes, and took a few steps back.

However, the ninja seemed to have already sensed his discomfort, and with his long sword in hand, he charged straight at him.

Koki's face was as cold as frost, and a sharp, frosty glint flashed in his eyes.

In the blink of an eye, the lightning of the Lightning Blade tore through the curtain of darkness, shooting out with the force of thunder, transforming into a sharp blade of light aimed directly at the ninja.

The ninja remained unmoved, maintaining his attacking stance, his hand seals rapidly forming.

Koki's gaze was fixed intently, as she silently considered the ninja's next move.

"Water Release: Waterfall Current!" With a thunderous roar, a mighty column of water Dotō and crashed towards Koki.

The thick column of water was unstoppable, and in the blink of an eye, it collided violently with Lightning Blade.

Lightning Blade, a lightning-attribute blade, unleashes thousands of electric threads upon contact with water, bursting forth like fireworks and weaving streaks of light across the water.

The water's conduction amplified the energy of the Lightning Blade instantly, and then the water, carrying the lightning, shot towards Koki.

Koki turned cold, and she instinctively leaped up lightly, deftly avoiding the fierce current.

However, at that very moment, fate seemed to play a cruel joke.

His figure fell, landing precisely on the seal of the central platform, where a mysterious object, resembling an eye, lay.

Almost at the same moment, Koki felt wave after wave of pain, like sharp blades piercing her heart.

He closed his eyes in agony, the burning pain like a powerful heartbeat pounding against his nerves. In that instant, his body lost control, as if all his strength had been drained away, making it almost impossible for him to stand.

Just as Koki was caught in a vortex of pain, the ninja saw an opportunity and prepared to seize the moment and launch another attack.

Unexpectedly, at this critical moment, several sharp blades of light suddenly flew from behind him.

The ninja nimbly dodged these sudden threats.

Looking up again, she saw Naruto streak across the sky like a golden lightning bolt, resolutely standing in front of Koki, his tone cold and hard. "You bastard, you're asking for death."

Anger flashed in Naruto's eyes. He spread his five fingers, and several Kunai like arrows from a bow, aimed directly at the ninja.

Naruto followed closely behind, and taking advantage of the ninja's Kunai, he threw Shuriken with lightning speed.

The roar of battle echoed through the space as Naruto and the ninja tumbled and rolled in the darkness, neither gaining the upper hand.

Despite the excruciating pain in her eyes, Koki desperately tracked Naruto's movements. She understood that although Naruto seemed to be attacking the ninja with all his might, he was actually preventing the ninja from getting closer.

Suddenly, excruciating pain struck again like a violent storm.

Koki clenched her teeth and closed her eyes again, this time almost exhausted even the strength to open them.
