The Relic's Secret Key Attracts Anbu Remnants, Otsutsuki Crest Hides a Ninja World Crisis

Sunlight from the Konoha office window spilled over the documents on Tsunade's desk. Su Ye, Naruto, and Sasuke stood before her; though their wounds had yet to fully heal, the exhaustion and relief in their eyes were unmistakable. Tsunade set down her pen and looked at the three of them. "The Void Remnants across the ninja world have been largely cleared, and the main strongholds of the Dark Organization have been razed. However, intelligence suggests that some remnants are still at large. We cannot afford to let our guard down."

Su Ye nodded and handed a report to Tsunade. "We discovered this black scroll carried by a Dark Organization member on the battlefield at Cloud Thunder Gorge. The runes on the scroll are linked to the ruins of the Otsutsuki clan." Tsunade took the scroll, her brow furrowed. "Otsutsuki ruins? Could the remnants of the Dark Organization be attempting to acquire power through these sites?"

Just then, the door to the Hokage's office was pushed open, and Shikamaru Nara rushed in with an urgent report. "Lady Tsunade, it's bad! A powerful chakra fluctuation has erupted from an ancient ruin on the border of the Land of Fire. According to our sensors, that site is an Otsutsuki ruin!" Su Ye, Naruto, and Sasuke exchanged glances, a flicker of vigilance flashing in their eyes.

Tsunade stood up immediately. "Su Ye, Naruto, Sasuke, head to the ruins on the border of the Land of Fire at once and investigate. Remember, no matter what you encounter, prioritize your own safety above all else." The three nodded, turned, and sped off toward the ruins.

The Otsutsuki ruins on the border of the Land of Fire were hidden within a dense forest. The entrance was covered in ancient runes that pulsed with a pale blue light, radiating a dense Otsutsuki chakra. Su Ye activated his Nine-Tomoe Rinne Sharingan, his ocular power piercing through the runes to see inside. Countless Dark Organization members were busy at work, holding black instruments as they seemingly attempted to crack the seal of the ruins.

"The Dark Organization remnants are really here!" Naruto roared, golden Tailed Beast chakra surging around him. "Let's go in and stop them!" Sasuke held Naruto back, saying calmly, "Wait. The seal of the ruins hasn't been fully broken yet. If we rush in blindly, we might trigger the ruins' defensive mechanisms."

Su Ye took a deep breath, a chakra blade coalescing in his palm. "I will infiltrate the ruins first to determine their objective. You two stand guard on the perimeter; if there is any movement, provide support immediately." With that, he channeled the power of his Six Paths Immortal Bones, his body turning into a pale purple stream of light as he slipped silently into the ruins.

Inside the ruins lay a massive cavern. In its center floated a gigantic pale blue crystal, covered in the crests of the Otsutsuki clan. The leader of the Dark Organization, a mysterious figure cloaked in black, stood before the crystal, hands weaving seals as black chakra flowed continuously into the stone.

"Leader, the seal is about to be broken! Once we obtain the Otsutsuki power within the crystal, we can resurrect Orochimaru and regain control of the ninja world!" one of the Dark Organization members shouted in excitement. The mysterious figure sneered. "Hmph, resurrecting Orochimaru is merely part of the plan. The true goal is to use the Otsutsuki power to open a path to the Otsutsuki homeworld, allowing the clan to descend upon the ninja world once more!"

Su Ye's pupils constricted; he had not expected the remnants of the Dark Organization to harbor such a deranged plan. He tightened his grip on his chakra blade, preparing to strike, when he suddenly felt a violent surge of chakra—the seal had been completely broken. The pale blue crystal erupted with blinding light, and a massive pillar of energy shot from it, piercing the clouds.

"Not good!" Su Ye teleported in front of the crystal and slashed his chakra blade toward the mysterious figure. The figure, however, was prepared; he turned and released a black chakra barrier, blocking the attack. "Su Ye, you really did come." The figure removed his mask, revealing a strange face covered in Otsutsuki crests. "I am a descendant of Otsutsuki Hagoromo, Otsutsuki Retsu. Today, I shall return the ninja world to the control of the Otsutsuki clan."

Otsutsuki Retsu waved his hand, summoning countless black chakra blades that swarmed toward Su Ye. Su Ye channeled the power of his Six Paths Immortal Bones, forming a pale purple barrier around himself while unleashing a dojutsu—Six Paths: Ultra-Big Ball Rasengan—which he launched at Otsutsuki Retsu. Retsu sneered, his body turning into a streak of light to evade the attack while releasing a secret technique of the Otsutsuki: Yomotsu Hirasaka. Countless black spatial rifts appeared around Su Ye, attempting to swallow him whole.

Su Ye immediately activated the dojutsu of his Nine-Tomoe Rinne Sharingan—Time Reversal. His figure vanished instantly, reappearing behind Otsutsuki Retsu, and he thrust his chakra blade toward the man's heart. Retsu, however, countered by releasing a blast of pale blue chakra that struck Su Ye in the chest. Su Ye spat out blood, his body sent flying backward until he slammed heavily into the cavern wall.

"Su Ye!" Hearing the commotion inside, Naruto and Sasuke rushed into the ruins. Seeing Su Ye injured, Naruto roared, his golden Tailed Beast chakra surging as the silhouettes of the nine Tailed Beasts manifested behind him. "How dare you hurt Su Ye! I won't forgive you!" He wove seals rapidly, golden chakra coalescing in his palm into an ultra-large Rasengan, the energy of a Tailed Beast Bomb swirling within it as he launched it at Otsutsuki Retsu.

Sasuke activated his Rinnegan and released Chibaku Tensei, a black gravitational core rapidly forming in the air to trap Otsutsuki Retsu. Retsu sneered, his internal Otsutsuki chakra exploding outward; the Chibaku Tensei was shattered instantly, and the ultra-large Rasengan was swallowed by his Yomotsu Hirasaka. "You think you can stop me with this level of power?" Retsu waved his hand, releasing a massive pale blue chakra blade that swept toward Naruto and Sasuke.

Su Ye struggled to his feet, his chakra blade coalescing once more. He channeled the power of his Six Paths Immortal Bones, merging his pale purple chakra with that of Naruto and Sasuke to form a colossal chakra giant. The giant held twin blades, blocking Otsutsuki Retsu's attack before launching a counter-offensive. Retsu remained unfazed, releasing the ultimate secret technique of the Otsutsuki—Amenominaka—sucking Su Ye, Naruto, and Sasuke into a strange dimension.

This space was an endless desert under a blood-red sky, the air thick with dense Otsutsuki chakra. "This is my exclusive dimension. In this space, I am a god!" Otsutsuki Retsu's voice echoed through the void as his body grew larger, a pair of massive pale blue wings sprouting from his back, his appearance becoming truly terrifying.

Naruto roared, his golden Tailed Beast chakra manifesting as countless Tailed Beast Bombs that rained down on Otsutsuki Retsu. Sasuke activated his Rinnegan and released Susanoo, which wielded twin blades and slashed toward Retsu. Su Ye activated the dojutsu of his Nine-Tomoe Rinne Sharingan—Six Paths: Void Purification—a pale purple beam of light erupting from his body in an attempt to purge the Otsutsuki chakra from the dimension.

Yet Otsutsuki Retsu only sneered. As he flapped his wings, countless pale blue chakra blades swarmed toward the three. The arms of the chakra giant were severed in an instant, and the attacks from Naruto and Sasuke were easily neutralized. "It's useless." Otsutsuki Retsu walked slowly toward them. "Within Amenominaka, your power will be continuously suppressed, while my own will rise without end."

Su Ye took a deep breath, the power of the Six Paths Immortal Bones within him beginning to surge wildly. He recalled the words of Hamura: "The true power of the Six Paths Immortal Bones can only be fully awakened through a heart that seeks to protect." He closed his eyes, his mind filled with images of his comrades in Konoha, the peaceful scenes of the ninja world, and his own resolve to protect it all.

In an instant, the power of the Six Paths Immortal Bones within Su Ye erupted completely. Within the pale purple chakra, the silhouette of the Sage of Six Paths appeared. "This is... the power of the Sage of Six Paths!" Otsutsuki Retsu's pupils constricted, an expression of disbelief crossing his face. Su Ye opened his eyes, his Nine-Tomoe Rinne Sharingan flashing with pale purple light. He reached out, his chakra coalescing into a massive blade. "Otsutsuki Retsu, your plan ends here!"

Su Ye leaped forward, his blade slashing toward Otsutsuki Retsu. Retsu immediately released Yomotsu Hirasaka, attempting to evade the strike, but Su Ye's blade, imbued with the power of the Sage of Six Paths, pierced through space and struck him in the chest. Otsutsuki Retsu let out a miserable cry as the Otsutsuki chakra within him began to destabilize, and the dimension of Amenominaka began to collapse.

"No! I will not accept this!" Otsutsuki Retsu roared, his chakra exploding in a desperate attempt to take Su Ye down with him. Su Ye sneered and released the Six Paths: Sealing Jutsu, pale purple sealing runes wrapping around Retsu's body and sealing him away completely.

As the Amenominaka dimension collapsed, Su Ye, Naruto, and Sasuke were transported back to the ruins. The pale blue crystal in the ruins, having lost the infusion of Retsu's chakra, began to dim. Su Ye stepped forward, placed his hand on the crystal, and channeled the power of the Six Paths Immortal Bones, attempting to seal the crystal for good.

But just then, the crystal erupted with blinding light, and a stream of pale blue energy shot out, merging into Su Ye's body. In his mind, fragments of strange memories suddenly surfaced—the origin of the Otsutsuki clan, the birth of the ninja world, and the secrets of the Otsutsuki homeworld.

"So that's how it is." Su Ye opened his eyes, a flash of realization in his gaze. "Otsutsuki Retsu's plan wasn't just to open a path to the Otsutsuki homeworld; he wanted to use the power within the crystal to awaken the true body of Kaguya Otsutsuki, who was sealed within the ninja world."

Naruto and Sasuke walked to Su Ye's side, looking at him with concern. "Su Ye, are you alright?" Su Ye shook his head and smiled. "I'm fine. The remnants of the Dark Organization have been dealt with, and Otsutsuki Retsu has been sealed. The ninja world can finally return to true peace."

The three turned and began walking back toward Konoha. Yet they did not know that deep within the crystal, a faint, pale blue stream of light was quietly stirring—the consciousness of Kaguya Otsutsuki had awakened, and a new crisis was quietly brewing.

Back in Konoha, Tsunade looked at the three of them with a gratified smile. "You've worked hard. The peace of the ninja world could not exist without your contributions." Su Ye, Naruto, and Sasuke nodded, their hearts filled with a sense of accomplishment.

But at that very moment, Su Ye suddenly felt a violent surge of chakra—coming from the direction of the Earth's core. His expression changed drastically. "No! Kaguya Otsutsuki's consciousness has awakened! She is attempting to break through her seal!"

The expressions of Tsunade, Naruto, and Sasuke turned grave in an instant. "We must go to the Earth's core now!" Su Ye said, channeling the power of the Six Paths Immortal Bones as he teleported toward the center of the world. Naruto and Sasuke followed immediately behind.

At the Earth's core, the pale golden seal holding Kaguya Otsutsuki was flickering incessantly, surrounded by thick, swirling pale blue chakra. Kaguya Otsutsuki's consciousness was pushing through the seal, releasing a powerful pressure upon the ninja world.

"Su Ye, you have finally arrived." Kaguya Otsutsuki's voice echoed through the Earth's core. "A hundred years ago, I was sealed by the Sage of Six Paths. Today, I shall finally descend upon the ninja world once more and bring this world under my absolute control."

Su Ye tightened his grip on his chakra blade, a flicker of resolve in his eyes. "Kaguya Otsutsuki, don't count on it! Today, we will surely seal you once again and protect the peace of the ninja world!"

Naruto and Sasuke also released their chakra, preparing for the final showdown with Kaguya Otsutsuki. A battle concerning the fate of the ninja world was about to unfold once more. And this time, Su Ye, Naruto, and Sasuke would use their power to safeguard the peace of the ninja world, ensuring that the tragedy of a century ago would never be repeated.
