Naruto: I Just Want To Become Immortal And Have A Harem

The First Year of Konoha

Above the Hokage Rock, one could see a boy with long black hair, wearing Gucci clothes and shoes, sitting on Hashirama's stone face.

Ryujin looked down at the Konoha Village being built below and couldn't help but be stunned.

"There is no doubt that I've transmigrated into the world of Naruto," Ryujin exclaimed in his mind, a very happy expression on his face.

He had always been fascinated by the Naruto world after watching the anime.

Why, you ask? Because Ryujin is a big fan of shinobi, martial arts, xianxia, wuxia, and just really likes anime and novels related to these worlds.

But suddenly, Ryujin heard a mechanical voice in his head: "What you have transmigrated into is not the ordinary Naruto world from the anime, but a space-time matrix composed of seven parallel Naruto worlds.

Every time and space world is the same as normal time and space, only the time nodes are different.

The main mission is being assigned to the host: choose a faction in each time and space to unify the shinobi world and ensure that there will be no division within twenty years after unification.

After completing the main mission, the host can become a True Immortal immediately and live forever."

"Good news: I have a system, and it seems to be rewarding," Ryujin thought to himself, though he was a little shocked that he didn't feel any surprise even after getting a system.

It just seemed like he had become Mahoraga, adapting to everything. But it still didn't make any sense to him.

"Bad news: The main tasks of the system is not easy to complete and is almost impossible to complete to be exact}

"This is the Naruto world! The freaking Naruto world!

Some shinobi here have the power to destroy the entire world, while the tailed beasts are even more dangerous to face.

A few minutes ago, I was just an ordinary, good student living a modern life. How the hell did I suddenly transmigrate into the Naruto world?

Ryujin thought, his footsteps faltering as he began to pace back and forth, hands running through his hair in frustration.

"Isn't there supposed to be a procedure where you meet some 'Random Omnipotent Being' who grants you cheat codes and stuff so broken that readers complain the MC can one-shot Madara when he's just a sperm in his father's balls?"

Ryujin muttered under his breath, a hint of sarcasm coloring his tone as he stopped and stared at the sky in disbelief.

He huffed and crossed his arms, narrowing his eyes as he continued his internal monologue. Moreover, one faction has to be chosen to complete the unification, and the unification needs to last at least 20 years before this damn system considers it valid.

Not to mention there are seven time-spaces, meaning Ryujin has to do this unification bullshit a total of seven fucking times! He clenched his fists, his body tense with irritation.

Even if Ryujin is familiar with the entire Naruto world's history and future, the level of this mission is still at plus-max level. He let out a long, exasperated sigh, slumping his shoulders slightly as if the weight of the task had just hit him.

Fortunately, the system soon started sending information about the assistance it would provide.

One: You can travel to any time and space at will, with ten opportunities to travel every day, and there is no limit to the length of stay.

Two: After binding with a faction in a time and space, you will receive a newbie gift package.

Three: After completing the unification of a world, you will receive a system reward and unlock new system functions.

As all this information flooded into his mind, Ryujin's eyes widened slightly, and a small smirk played on his lips. With the help of this system, he thought, I might actually be able to pull this off!

His stance straightened, and he clenched his fists with renewed determination. After all, the final reward of the system is really tempting.

"Become an Immortal immediately and live forever," he whispered to himself, his voice low but filled with resolve.

He would fight for it no matter what! He was only afraid at first because the reward of becoming immortal is useless if he dies trying to unify this world. But now, with the system backing him up, Ryujin felt the stirrings of hope.

"Let's bind with Konoha and see what reward I get!" Ryujin declared, his voice brimming with anticipation as he paced in circles, unable to contain his excitement.

He mentally chose to bind with [Konoha Ninja Village] on the system panel, feeling a small thrill as he received the 'Newbie Gift Pack.'

Why choose Konoha? Of course, it's to reduce the difficulty.

Although Ryujin didn't like Konoha very much—more accurately, he didn't like certain people in Konoha—he couldn't deny its strategic advantage.

Looking at the entire history of the ninja world, no matter the era, Konoha had the best overall strength and was the best option for completing the unification of the ninja world.

Not to mention, there have been two reincarnations of Asura and Indra. Ryujin scoffed, a smirk tugging at his lips.

Are the other ninja villages and forces really going to compete with Konoha? It's like Kishimoto saying, "I love all my children equally," but in reality, Konoha is the clear favorite.

Ryujin had no reason to ignore the simple mode and insist on choosing hell mode; he wasn't a masochist. His primary goal was to complete the main mission.

[Ding—the novice gift package has been opened]

[Congratulations, you got a pair of (Tenseigan eyes)! (Automatically awakened)]

[Congratulations, you have received a space-time ninja tool (Storage Bag)!]

[Congratulations, you have obtained three (Modern Physical Exchange Coupons)!]

Ryujin's heart raced with excitement as he saw the system's rewards. Without hesitation, he pulled out his iPhone to check his reflection.

His hands shook slightly as he focused on the screen, and there, staring back at him, was a pair of corrugated Tenseigan, glowing with an otherworldly light.

His vision sharpened instantly, and he gasped in amazement, blinking rapidly as he adjusted to the new clarity.

He could now clearly count the compound eyes of flies buzzing in the distance—an ability far beyond his previous human limitations.

Ryujin's eyes darted around, testing his newfound vision, his breath catching as the world seemed to slow down, every detail crisp and vivid.

It took a while for Ryujin to reluctantly calm himself down, his chest rising and falling as he steadied his breathing. He needed to adapt to the terrifying dynamic vision brought by his new pupils.

In addition, Ryujin noticed that he couldn't use the other abilities of the Tenseigan yet, aside from limited teleportation, and even that was within a small radius.

He frowned slightly, trying to push his power further but feeling a block, like hitting an invisible wall.

He didn't know how, but as soon as he awakened the Tenseigan, he instinctively knew all its abilities and how they worked, just like an Uchiha knows about the abilities of his Mangekyou Sharingan as soon as he awakens it. He exhaled slowly, his mind racing with possibilities.

The reason he couldn't fully tap into the abilities of the Tenseigan became clear—he didn't have chakra in his body, and he also didn't know how to create it.

Sure, he knew the process in theory, but seeing something work in anime and doing it in real life was like comparing Sakura to Kaguya—worlds apart.

Though he couldn't yet wield the full power of the Tenseigan, just having these eyes was enough to intimidate and convince many people. The Tenseigan was on a level comparable to, if not greater than, the Rinnegan.

Without these eyes, Ryujin thought with a shiver, as an ordinary person, just contacting Senju Hashirama and other Hokages or faction leaders in other spaces and times would be incredibly dangerous, if not outright impossible.

"The system is still very powerful, and the novice gift pack is also very good," Ryujin mused as he stood up from Hashirama's stone face.

His movements were deliberate, almost reverent, as he dusted himself off, his eyes narrowing with determination.

"Let's go. First, I need to meet Senju Hashirama, the God of Shinobi in this era," he muttered, his voice low but filled with resolve.

As he stood up, he looked toward the distant Hokage Building, or mansion—whatever you might call it.

This era was actually the best time to complete the unification of the ninja world. The major ninja villages had just been established, and Konoha's side had almost absolute crushing power.

Senju Hashirama and Uchiha Madara alone were enough to sweep the entire ninja world, forcing everyone to their knees.

"Susanō and the Wood Buddha—those two could destroy the entire world," Ryujin thought, his mind racing with the enormity of the task ahead.

But precisely because of this, the difficulty lay with Hashirama and Madara. He frowned, his steps slowing as he considered his approach.

The stronger the person, the stronger their heart and will. It wouldn't be easy to persuade them to change their beliefs and paths.

Not everyone was as easily convinced as Nagato. Ryujin shook his head, knowing that if he wasn't careful, after talks collapsed, he might end up facing Susano'o and the Wooden Buddha alone.

…

{Time and Space: First Hokage}

Time: The First Year of Konoha

{Unification Progress: 30%}

Outside the Hokage Building, Senju Hashirama, who had just finished his work for the day, pushed open the door with an excited smile on his face.

The warm evening air greeted him, but before he could fully step out, Senju Tobirama's roar echoed from inside the Hokage mansion.

Hashirama paused mid-step, his face twitching slightly at his brother's outburst, before sighing and turning to see what the fuss was about.

"Brother, where do you think you're going?" Tobirama yelled as he came running outside the Hokage mansion, his footsteps heavy with urgency.

"For fresh air..." Hashirama replied, his expression deadpan and eerily calm, reminiscent of Saitama. He stood there, hands in his pockets, trying to appear nonchalant.

"Are you going to gamble again? Don't forget your current status, brother! There are still so many official duties waiting for you to handle!"

Tobirama's eyes narrowed, suspicion lacing his voice as he folded his arms across his chest.

"No, no, I'm not going to gamble..." Hashirama said, turning his face away, trying to hide his guilty expression. He avoided his brother's gaze, but the slight twitch in his lips betrayed him.

Tobirama wasn't fooled. He quickly grabbed Hashirama's hand, forcing him to face him.

"Could it be that you're looking for that guy, Madara?" Tobirama asked, his voice low but firm, eyes searching his brother's face for any sign of deceit.

"Tobirama, how did you know?" Hashirama blurted out, his eyes widening in surprise.

"Humph! Only when you're meeting that guy do you get this happy and excited, brother!"

Tobirama folded his arms again, this time with a huff of dissatisfaction. His gaze was sharp, cutting through Hashirama's attempt at innocence.

"Is he your boyfriend or something!? Brother?" Tobirama suddenly yelled, his voice rising in anger, his eyes blazing as he leaned in closer.

Hashirama's face turned bright red, his mouth opening and closing as he stammered, "Maybe..."

"Maybe? WHAT THE FUCK DO YOU MEAN, MAYBE? GET YOUR ASS BACK INSIDE THE MANSION BEFORE I GRAB MOTHER'S SLIPPERS AND WHOOP THAT ASS!"

Tobirama threatened, his voice booming with authority as he took a step closer, towering over his older brother.

The threat hit home, and Hashirama suddenly froze, a look of horror flashing across his face as he remembered the days when his mother would whoop his ass with her wooden slippers. The memory was vivid enough to make him wince.

Realizing he might have pushed the joke too far, Hashirama quickly backtracked, waving his hands defensively. "Hahaha, I'm just joking! Madara asked me to meet him at the Nanga Shrine of the Uchiha clan.

It must be for something important," he said with a naive smile, rubbing the back of his head sheepishly, trying to diffuse the tension.

"Nanga Shrine? That guy Madara has become more and more bold recently, and I don't know what he's planning. Brother, please pay attention to me! Don't be fooled by him again!"

Tobirama's voice was sharp, almost pleading, as he watched his elder brother with a mix of concern and frustration.

He knew deep down that he couldn't stop Hashirama from seeing his old friend—his old sweetheart, as Tobirama bitterly thought—but he couldn't help but yell after him.

Fortunately, Hashirama had already assumed the position of First Hokage, so even Madara shouldn't be able to cause too much trouble.

"Okay, okay!" Hashirama waved his hand dismissively, already half-turned to leave. "I'm leaving first. Tell Mito for me that I won't be back tonight..."

Tobirama's face darkened, his mouth opening in stunned silence. He stared at his brother, speechless, a cold sweat breaking out on his forehead. "..."

'What does he mean he won't come back tonight? What's going to happen in that cursed place?' Tobirama thought, giving Hashirama a side-eye filled with suspicion.

But just as Hashirama turned around to leave, he suddenly froze.

A figure appeared out of thin air across the corridor! It wasn't the Flying Thunder God technique—it was more secretive, more sudden, with no warning and no chakra fluctuation at all. Hashirama's heart skipped a beat as he took in the sight before him.

The newcomer had long black hair, cascading down his back, and wore a strange, out-of-place shirt that didn't match the style of the ninja world.

But what struck Hashirama most were the eyes—deep, rippling orbs that looked eerily like the [Tenseigan], rumored to represent the highest order a pair of eyes could reach.

Hashirama tensed up immediately, his body going rigid as he prepared for anything. But even as his muscles coiled in readiness, he kept his voice calm, his eyes narrowing as he asked, "Who are you?"

The figure tilted his head slightly, his expression unreadable. "First Hokage Senju, do you have time to chat?" Ryujin asked, his tone polite but firm, his eyes never leaving Hashirama's.
