Simultaneous Transmigration: From Douluo Continent to the Pinnacle

Parallel world, Konoha Village, Hokage's office.

Tsunade sat on the Hokage's chair, a symbol of supreme power, with her legs crossed and a cup of tea in one hand.

Sunlight streamed through the glass windows, illuminating the entire office with a bright and warm glow.

On the desk in front of her lay a scroll that had just been delivered, the ink still fresh.

She had read the contents of the scroll three times, and now she was frowning slightly, as if she was considering something extremely important.

"A spatial portal?" Jiraiya sat on the opposite sofa, arms crossed, his eyes unusually serious. "Are you sure you want to send the younger generation there? We don't know that world well enough. What if something goes wrong..."

"That's precisely why we need to send someone over to investigate," Tsunade said, setting down her teacup with an undeniable air of decisiveness. "The intelligence scroll clearly states that Uchiha Yao hails from Konoha in another world. That world also has the Uchiha clan, a ninja system, and even the foundations of ninjutsu are identical. What does this mean? It means that it's a parallel world highly similar to ours, yet it has taken a different path. Our understanding of that world is limited to his accounts and written intelligence, but no matter how well he describes it, it's never as good as seeing it with your own eyes."

She stood up, walked to the window, and gazed at the bustling village. The streets were teeming with people, shops lined the streets, and the energetic shouts of young ninjas echoed from the training grounds. She paused for a moment, then slowly spoke: "I unified Konoha's power not to live a life confined to this small patch of land. Uchiha You has opened the door to another world. If we don't make good use of this opportunity, that would be truly foolish."

"Didn't you yourself say that that world experienced a split between black and white, with the black side being driven out and hated..." Jiraiya stroked his chin. "Tell me, what exactly was Konoha like in that world?"

Tsunade shook her head: "I don't know. That's why we need to go see. I plan to send you to lead the team, with Kakashi assisting, along with Naruto, Hinata, Ino, and the rest of the younger generation. They represent the future of Konoha, and they should go out and see what the outside world is like."

"Aren't you afraid there might be some kind of trap over there?" Jiraiya raised an eyebrow.

"If Uchiha Yao wanted to harm Konoha, with his strength, he wouldn't need to go to such lengths." Tsunade's lips curled into a confident smile. "His opening of the space portal for our ninjas to move freely shows he has confidence and sincerity. Besides..." She paused, her gaze deepening, "I also want to see just how far Konoha has developed in this other world. A place that can nurture Uchiha Yao can't be much worse than ours."

Jiraiya remained silent for a moment, then finally stood up and stretched. "Alright, since you've decided, I have no objections. When do we set off?"

"Three days from now." Tsunade turned around. "Before that, there's one more thing I need to take care of."

"What is it?"

"It's time to see the results of Sasuke's training. I heard he's been training at the clan's ruins lately and seems to have made some breakthroughs." Tsunade's smile deepened slightly. "It's also time for him to settle things with Itachi."

The ruins of the Uchiha clan's territory were bathed in the cold moonlight.

The mottled walls cast long shadows in the moonlight. Those houses that once bore the Uchiha clan crest are now nothing but ruins, gradually turning into silent wastelands under the erosion of time. The wind howls through the collapsed pillars, as if whispering the tragedy of that night.

Sasuke stood in the center of the ruins, his black robes fluttering in the night wind. His gaze calmly fell upon the figure standing not far ahead, also atop the ruins—Uchiha Itachi, his elder brother.

The man he had hunted down for years, the one he hated to the core, now stood less than ten feet away from him, wearing his signature red-cloud-patterned black robe, his face as calm as ever. Only now, in his crimson Sharingan eyes, there was an inexplicable sense of relief.

"Your eyes..." Itachi gazed into Sasuke's eyes, his voice calm yet carrying a barely perceptible hint of relief, "are no longer just the Mangekyou Sharingan."

"You taught me," Sasuke said slowly, his tone as calm as a deep pool. "The power of hatred, the power of pain. I grew stronger the way you taught me, and finally, I've reached this point."

Itachi didn't reply, but looked into Sasuke's eyes in silence for a long time. Then he smiled softly, a gentleness he had never shown in front of Sasuke before: "Come, let me see just how much you've grown over the years."

Before he finished speaking, Itachi's figure had already vanished from the spot. The next second, he appeared several feet above Sasuke's head, his right hand forming a hand seal, and a massive fireball roared towards the ground. It was the Uchiha clan's most famous Fireball Jutsu, but the power it unleashed in Itachi's hands was far beyond what ordinary Uchiha clan members could achieve. The crimson flames, accompanied by scorching heat, were like a falling sun, completely dispelling the shadows in the ruins.

Sasuke didn't dodge. He raised his head, and a strange light suddenly shone in his Sharingan eyes. The next moment, Itachi's fireball stopped abruptly three zhang away from Sasuke, as if it had hit an invisible barrier. It twisted and deformed violently, then deflected at a strange angle and smashed into the ground beside Sasuke, creating a large crater.

"Stronger eye power." Itachi's Sharingan narrowed slightly. He landed on a broken wall ten feet away and quietly looked at Sasuke. "You've even learned the space distortion technique of 'Kamui'? No, that feeling is more like pure eye power suppression—you used your own power to change the trajectory of my ninjutsu."

"I've told you, I'm no longer the brat who just followed you around." Sasuke slowly took a step forward. Fine lightning crackled beneath his feet, spreading across the ground like living things, enveloping the entire ruins in a blue-white electric net. Lightning Release: Ninja Taijutsu—his fighting style combined lightning chakra with taijutsu. Each bolt of lightning was an extension of his body, each strand of electricity containing the power to pierce steel.

Itachi narrowed his eyes slightly. He formed a hand seal with his right hand, attempting to use Amaterasu, but the instant his eye power was activated, an even stronger eye power surged from Sasuke's side, like an invisible wall, forcefully suppressing his Amaterasu. Black flames appeared a few feet in front of Itachi and then quickly vanished, like a struggling candle flame being mercilessly extinguished by a gust of wind.

"Amaterasu was also..." Itachi murmured to himself.

"I already said." Sasuke's figure instantly covered ten feet, appearing in front of Itachi and striking him in the chest with a palm strike. "The same trick won't work on me."

The palm strike, imbued with the power of thunder, exploded in a dazzling blue-white light before Itachi. Itachi crossed his arms in front of his chest, taking the blow head-on. His body was propelled far by the force, his feet carving two deep furrows in the ground. Amidst the dust, a trickle of blood escaped Itachi's lips, but a faint smile appeared on his face.

"The aura of Sage Mode... have you mastered it too?"

"Not only." Sasuke formed hand seals, and his aura suddenly changed. A vast and ancient chakra surged from his body, faint orange lines appeared around his eyes, and the outline of his Sharingan became clearer and sharper. That was Sage Mode, which he had learned from Mount Myōboku, perfectly fused with his Mangekyou Sharingan, forming a unique form of power that belonged only to him.

"This is no ordinary Sage Art." Itachi wiped the blood from the corner of his mouth, his eyes filled with scrutiny. "You have fused your Sharingan power with Sage Chakra, creating a unique style of your own."

"At the end of this path lies the Eternal Kaleidoscope." Sasuke didn't deny it. "I've touched that boundary. Just one more step and I can truly grasp the final form of those eyes."

Itachi was silent for a moment, then smiled. His smile held a sense of relief, as if he had finally seen the day he had been waiting for arrive. He slowly straightened up, his hands forming a complex hand seal: "Since that's the case... let me see if you can withstand my final attack."

A massive surge of chakra suddenly erupted from his body, containing an ancient and profound aura of ocular power. It was his final trump card, the ultimate form of Susanoo. A semi-transparent crimson giant rose from his body, wings spread, wielding a sharp blade, like a war god descending to earth.

Sasuke looked up at the Susanoo, showing no retreat, no fear, and not even a change in expression. He slowly raised his right hand, ripples spreading across his palm, and a powerful aura of ocular energy poured forth from his body. In the next instant, a deep purple giant rose up behind him, its height comparable to Itachi's Susanoo, its body wreathed in lightning and flames, radiating an even more solid and imposing pressure.

Two Susanoo stood facing each other across the ruins.

Itachi's crimson Susanoo and Sasuke's deep purple Susanoo moved simultaneously. The two giants collided like ancient beasts, the shockwave blasting away all the broken walls and debris within a radius of dozens of feet. Crimson blades swept across, and deep purple fists slammed down, each collision stirring up clouds of dust and swirling air currents. However, as time passed, cracks began to appear in Itachi's Susanoo, while Sasuke's Susanoo remained as solid as a rock, like two mountains colliding, one of which was already showing signs of collapse.

That's the difference in pupil power.

Sasuke's Mangekyou Sharingan has reached the limits of eternity, and his ocular power reserves far surpass Itachi's. Meanwhile, Itachi's years of illness and constant strain have brought his Susanoo to the brink of collapse. He is facing an opponent far stronger than himself with his already weakened state.

Finally, a crisp cracking sound rang out. Itachi's Susanoo shattered into countless rays of light under Sasuke's full-force attack, and Itachi's body flew backward, crashing heavily into the ruins. He struggled to get up, only to find that his chakra was completely depleted, and he couldn't even use the simplest substitution jutsu.

Sasuke slowly walked up to him, looking down at Itachi lying on the ground. The moonlight illuminated their figures, Itachi's pale face, and his serene smile.

"You've won." Itachi's voice was weak, yet carried a strange tranquility. "You've surpassed me, surpassed everyone in the Uchiha clan."

Sasuke didn't answer. The fighting spirit in his Sharingan was slowly fading, replaced by a complex and indescribable emotion. He remained silent for a long time before speaking in a low voice: "Why didn't you fight back? You clearly still had power left, why did you save it up until the very end?"

"I used it." Itachi coughed twice, the blood at the corner of his mouth particularly glaring in the moonlight. "But you've become so strong that all my attacks have become futile. You've truly mastered the power of the Sharingan, not by blindly chasing after it, but by truly controlling it."

Sasuke crouched down, gazing at the face that hadn't changed much from his memory. In the moonlight, Itachi's eyes were still crimson, but deep within them lay no longer any hostility or defensiveness, as if he had finally unloaded the heavy burden that had weighed on his shoulders for so many years.

"I've been waiting for you," Itachi said softly. "Waiting for you to become strong enough to defeat me, waiting for you to be able to walk the path of a ninja independently, waiting for the day when you no longer need to carry the hatred for me and can live a good life."

Sasuke didn't speak, he just watched him quietly. His hands clenched unconsciously, his knuckles turned white, and his nails dug deep into his palms.

"I know you didn't kill your clansmen," Sasuke suddenly spoke, his voice hoarse. "I know you were just following orders from higher-ups to protect the peace of Konoha. I also know... you've always been protecting me in your own way."

Itachi paused for a moment, then gave a weak smile: "You know everything."

"The person I should hate isn't you." Sasuke's voice grew lower. "The person I should hate is those who took advantage of you, and this twisted world. You just made your choice in that position."

Itachi watched him quietly for a long time, then slowly raised his slightly trembling hand. His fingers gently touched Sasuke's forehead, once, then again, just like the mischievous older brother many years ago who would gently place a finger on his younger brother's forehead. It was his habit, and also his wish—like an ordinary older brother wanting to leave his younger brother with a final, tender mark.

"You're right." Itachi's voice grew softer and softer. "This world is twisted. But you have the power to change it. You're stronger than me, you've gone further than me... So, I'm entrusting everything to you."

His arms slowly fell to his sides, his eyes gently closed, and the last expression on his face was a smile.

Moonlight shone on that serene face, as if time had finally forgiven this man, allowing him to lay down all burdens and sins in his final moments and depart in the most peaceful manner. Sasuke knelt beside Itachi and gently closed his eyes. His hands were covered in dirt and blood, but the movement was exceptionally gentle.

"I remember," Sasuke whispered, as if responding to a dying wish. "I will carry everything you have to do and change this twisted world."

He stood up, took one last look at the lifeless figure in the ruins, then turned and strode towards the moonlit distance.
