Training in the Void, Tempering the Edge; Threefold Resonance Shatters Shackles

Inside a medical tent on the border of the Land of Fire, pale green healing chakra swirled around Su Ye like flowing water. Tsunade concentrated pure chakra at her fingertips, meticulously repairing the meridians eroded by the power of the Void, beads of sweat seeping from her forehead. "The power of the Void within you has become entangled with your meridians; forcing it out will only cause greater damage. In the coming days, you must use the power of the Rinne to suppress it slowly. You must absolutely not force your chakra to fuse again."

Su Ye nodded, raising a hand to press against his left eye. Within his Rinne Sharingan, a pale purple glow intertwined with wisps of black mist, each rotation accompanied by a faint, stinging pain. Rhythmic footsteps sounded outside the tent, and Naruto burst in, still radiating the residual warmth of Kurama's chakra, followed by a grim-faced Sasuke. "Su Ye, are you alright? Just now at the training ground, the resonance of the three-colored chakra failed again."

Sasuke placed a golden-glowing scroll on the table—the "Three-Color Rinne Void Seal" manual left behind by the Uchiha ancestors. "Without your Rinne power to lead, the chakra between Naruto and me cannot form a stable resonance. Furthermore, I always feel there is a deeper secret hidden within the manual, but we are missing the key clue."

Su Ye reached out to touch the scroll, and his Rinne Sharingan flared to life. The pale purple light pierced the surface of the scroll, causing countless tiny runes to emerge and piece together an ancient line of text in the air: "Bloodline as the guide, intent as the bridge; when the three colors become one, the truth shall be revealed." His pupils constricted. "The key is 'intent.' The last time the fusion succeeded, it was because we faced a life-or-death crisis and trusted each other completely. Now that we are practicing deliberately, a barrier has formed instead."

No sooner had he finished speaking than Sage Fukasaku leaped in through the window, smoke curling from his pipe. "This old toad happens to have a method. The 'Trial of the Mind' at Mount Myoboku allows one to experience the most realistic tests within an illusion; perhaps it can help you break down your mental defenses. However, the trial is perilous; if you are not careful, you will be trapped in the illusion forever, unable to wake."

The three exchanged glances, a look of resolve flashing in their eyes simultaneously. Naruto patted his chest, Kurama's chakra swirling in his palms. "For the sake of the ninja world, what is a little danger like this!" Sasuke clenched his fists, the golden Power of the Fire Seed dancing at his fingertips. "As long as I can master the sealing technique, I can push through even an illusion."

The next morning, the three followed Sage Fukasaku to Mount Myoboku. The trial grounds were located at the "Mind Pool" deep within the mountain, the water shimmering with a faint blue light that reflected their figures. Sage Fukasaku performed a hand seal, and the pool rippled. "Step into the pool, and the illusion will unfold based on the deepest obsessions in your hearts. Remember, no matter what you see, you must not lose yourselves."

Su Ye was the first to step into the pool. Blue light enveloped his body, and the scene before him shifted abruptly. He stood amidst ruins, surrounded by the tragic aftermath of the ninja world being swallowed by the Void Realm. Gen appeared not far away, holding the corpses of Naruto and Sasuke, a mocking smile on his face. "Do you see? This is your so-called protection. If you submit to me, I will give you the chance to reshape the world."

Su Ye clenched his fists, his Rinne Sharingan flaring. "I will never submit to you!" He channeled his Rinne power, the pale purple chakra coalescing into a sword, and slashed toward Gen. But Gen's figure dissolved into black mist, merging with the surrounding ruins. Countless familiar faces emerged from the rubble—villagers consumed by the power of the Void, fallen Allied Forces soldiers, the sacrificed Obito. They reached out, their eyes filled with despair. "Su Ye, why didn't you save us?"

Su Ye's body trembled slightly. He knew this was an illusion, yet the sight before him was too real. Just then, the voice of Shisui echoed in his mind: "Remember, protection is not about self-reproach, but about carrying the hopes of the departed and moving forward." Su Ye snapped to his senses, his Rinne power erupting, the pale purple light dispelling the surrounding illusion.

When he opened his eyes, he was lying by the edge of the Mind Pool. Sage Fukasaku handed him a bowl of medicinal liquid. "Not bad, it only took you half an hour to break through the illusion. Next, it is Naruto's turn." Naruto took a deep breath and jumped into the pool. A flash of blue light, and he appeared in the Hokage office in Konoha.

Tsunade, Kakashi, and Jiraiya sat at the desk, their faces etched with disappointment. Tsunade spoke, "Naruto, you have disappointed us too much. Because of your recklessness, the Allied Forces have suffered heavy losses. From today on, you are no longer a ninja." Naruto tried to explain, but his throat felt blocked, unable to utter a sound.

At that moment, Gen's figure appeared outside the office. He raised a hand, and a black beam of light shot toward Konoha. Naruto roared, wanting to condense a Tailed Beast Bomb, only to find that the Nine-Tails chakra within him had vanished. He watched as the villagers fell in the black beam, his eyes filled with despair. "No!"

"Naruto, don't give up!" Kurama's voice echoed in his mind. "Power is not the only way to protect. Your persistence, your smile—that is the most powerful force." Naruto snapped to his senses, golden chakra erupting around him. The illusion shattered, and he leaped from the pool, his eyes flashing with a resolute light.

Finally, Sasuke stepped into the pool. A flash of blue light, and he returned to the night of the clan's massacre. The Uchiha clansmen lay in pools of blood, and Itachi appeared not far away. Sasuke roared, the golden Power of the Fire Seed coalescing into a sword, and slashed toward Itachi. "Why! Why did you slaughter the clan!"

Itachi did not dodge, letting the blade pierce his body. He reached out, stroking Sasuke's head, his eyes filled with complex emotions. "Sasuke, this is the fate of the Uchiha. To break this fate, you must accept the past." As the words fell, Itachi's figure turned into a golden light, merging into Sasuke's body.

The surrounding scene shifted, and Sasuke stood before the stone tablet of the Uchiha ancestral grounds. Gen's figure appeared behind the tablet. "Sasuke, as long as you submit to me, I will help you resurrect the Uchiha clan." Sasuke clenched his fists, the golden Power of the Fire Seed dancing at his fingertips. "I do not need resurrection. The glory of the Uchiha shall be protected by me!" He channeled the Power of the Fire Seed, and the golden light dispelled the illusion.

Once all three had broken through their illusions, the Mind Pool shimmered with three colored lights. Sage Fukasaku stroked his whiskers. "Very good, you have all passed the trial. Now, try the chakra fusion again; it should succeed." The three stood by the pool, Su Ye's Rinne power, Sasuke's Power of the Fire Seed, and Naruto's Tailed Beast power converging toward the sky like three colored pillars.

This time, the three types of chakra did not repel each other. The pale purple, golden, and orange-yellow lights intertwined, forming a massive three-colored vortex above them. The vortex spun faster and faster, and the surrounding space began to distort. A look of pleasant surprise flashed in Sage Fukasaku's eyes. "It succeeded! This is the true form of the Three-Color Rinne Void Seal!"

But just then, Mount Myoboku shook violently. A black beam of light shot down from the sky, and Gen's figure appeared within it. "I did not expect you to actually master the sealing technique. However, the game ends here." He raised his hand, and countless black chains shot out from the beam, coiling toward the three.

Su Ye and the others immediately activated the sealing technique. The three-colored vortex erupted with dazzling light, and a massive beam of energy blasted toward Gen. Gen's expression changed drastically, and dark golden chakra coalesced into a shield. The beam collided with the shield with a thunderous "bang." The massive shockwave sent the three flying, blood spraying from their mouths.

Gen sneered, raising his hand to conjure a massive demonic sword, and slashed toward them. "I let you escape by luck last time; this time, you will surely die!" At the critical moment, the Tailed Beasts appeared. Kurama, Matatabi, Isobu... all nine Tailed Beasts simultaneously launched Tailed Beast Bombs, blasting toward the demonic sword.

"BOOM!" The demonic sword shattered, and Gen was forced back by the power of the Tailed Beast Bombs. He looked at the beasts, a trace of surprise flashing in his eyes. "I did not expect you to be able to unite the Tailed Beasts. However, this is not enough!" Gen channeled the power of the Void, and black mist shrouded Mount Myoboku. Countless Demon Eater Lords surged from the mist, charging toward the three.

"Everyone, coordinate!" Su Ye shouted. He channeled his Rinne power, the pale purple chakra forming a massive spatial vortex that sucked in a large number of Demon Eater Lords. Sasuke condensed a golden flame sword, slaying a Demon Eater Lord with every strike. Naruto entered Nine-Tails Mode, the golden Tailed Beast chakra forming a massive fist that continuously pounded the Demon Eater Lords.

The Tailed Beasts also launched their attacks one after another. Kurama's Tailed Beast Bomb, Gyuki's ink, Shukaku's sandstorm... countless attacks wove into a massive net of firepower, slaughtering the Demon Eater Lords in droves. Sage Fukasaku led the Toad Army of Mount Myoboku, launching senjutsu attacks to purify the surrounding power of the Void.

Seeing this, Gen roared in anger. He channeled all his power of the Void, the black mist coalescing into a massive claw that swiped toward the three. "I will not admit defeat!" Su Ye and the others immediately activated the sealing technique. The three-colored beam condensed once more, blasting toward the claw. The claw collided with the beam, and the entire Mount Myoboku shook violently.

"Hold on!" Su Ye roared, increasing the output of his Rinne power. Sasuke and Naruto exerted their strength simultaneously. The power of the three-colored beam grew stronger, gradually suppressing the claw. Gen's body began to turn transparent, a trace of unwillingness flashing in his eyes. "I will not end like this! The armies of the Void Realm will soon trample the ninja world!" As the words fell, Gen's figure dissipated completely.

The black mist gradually dispersed, and the Demon Eater Lords, having lost their source of power, collapsed to the ground one by one. The three slumped to the ground, their chakra completely exhausted. The Tailed Beasts gathered around, and Kurama's voice echoed in their minds: "Not bad, brats. This time, I'll count it as your win."

Sage Fukasaku stepped forward, a gratified smile on his face. "Congratulations, you have not only mastered the sealing technique but also broken through your mental defenses. However, although Gen has been repelled, his true body remains in the Void Realm. Next, we must make full preparations to welcome the final decisive battle."

The three nodded. Su Ye looked at the sealing technique manual in his hand, a trace of determination flashing in his eyes. "Gen's army will arrive soon. We need to unite the Five Great Nations and integrate all our strength. This time, we must completely seal the Void Realm and protect the ninja world."

In the days that followed, the three began intensive preparations. Su Ye led experts in space-time ninjutsu to set up more solid spatial barriers along the borders of each nation; Sasuke returned to the Uchiha ancestral grounds to study advanced forms of the sealing technique; Naruto took the Tailed Beasts to train with the Allied Forces, improving the soldiers' combat capabilities.

The leaders of the Five Great Nations also held an emergency meeting. The Raikage slammed the table, lightning-style chakra dancing around him. "Kumogakure will send all its elites to cooperate with your actions." Gaara's sand iron swirled in his palms. "Sunagakure will also provide full support. As long as we can protect the ninja world, even if it means sacrificing our lives, we will not hesitate."

Tsunade looked at everyone, her eyes filled with gratification. "From today on, the Allied Shinobi Forces are officially established. Su Ye, Sasuke, Naruto, you three will serve as the commanders of the Allied Forces, leading us to confront the Void Realm." The three stood up simultaneously, their eyes flashing with a resolute light. "We will certainly not let everyone down!"

At this moment, within the Void Realm, Gen's true body emerged from the black mist, his dark golden armor gleaming with a cold light. He looked at the Uchiha mask in his hand, a trace of icy killing intent flashing in his eyes. "Su Ye, Sasuke, Naruto. Next time we meet, I will make you, and the entire ninja world, pay the price for your actions!" He raised his hand, and countless Void soldiers surged from the black mist, lining up in formation. A final decisive battle concerning the survival of the ninja world was about to begin.
