Reincarnated very op

{A/N: Sorry for the inactivity. I took a break, first to recover from my illness, and then to reread Solo Leveling to ensure I had everything clear before writing. Now, I'll follow a new rhythm since I'm going back to school, so expect a chapter approximately every two days.}

A New Life in a New World

A cold wind blew over Seoul as night enveloped the city in its dark embrace. Amid the countless lights flickering across the metropolis, a secluded alley hid an impossible phenomenon—a young man with black hair and piercing eyes had just appeared out of nowhere.

Sung Ryo opened his eyes and scanned his surroundings. He knew he had left the Naruto universe and was now in a completely different world: that of Solo Leveling. Unlike his previous reincarnations, this time, he had chosen an identity deeply rooted in this world. He was now the younger brother of Sung Jin-Woo.

____________________

A New Life

The Sung household was modest but warm. Jin-Woo, his older brother, had just returned from one of his part-time jobs, visibly exhausted. Ryo could sense the fatigue and weight of responsibility pressing down on his brother's shoulders. Their mother was still hospitalized, and Jin-Woo worked tirelessly to support them. Despite everything, he managed a smile upon seeing Ryo.

"Ryo, have you eaten?" Jin-Woo asked as he set down his bag.

Ryo nodded with a sincere smile. He wanted to enjoy this peaceful new life—at least until the System came into play.

______________________

Waiting for the System

Days passed, and Ryo easily adapted to his new role as the younger brother. He respected Jin-Woo's way of life while keeping a close eye on him. He knew that his brother would soon receive the System, and he himself would obtain a version that was 100 times more powerful and demanding.

He was eager. This world was filled with powerful enemies, and he intended to become the strongest to face them. But for now, he had to wait.

Jin-Woo, unaware of all this, continued sacrificing himself for their family. Ryo, in turn, felt deep respect for his older brother. Their bond was strong and sincere, and he intended to preserve it.

The System Awakens

Finally, the long-awaited day arrived.

The mission in the Double Dungeon. The screams. The massacre. Jin-Woo, covered in blood, accepting the survival quest. It was at that moment that Ryo felt a phenomenal power surge within him.

A blue window appeared before him:

DING! You have obtained the System. All rewards and abilities are multiplied by 100. Quests will be 100 times harder. Are you ready?

Ryo smiled.

The adventure was just beginning.

A First Step Toward Power

As Jin-Woo struggled to survive in the dungeon, Ryo felt his body tremble under the influx of energy from the System. He clenched his fists and sensed an unfamiliar strength awakening within him. Then, a new notification appeared before his eyes:

Daily Quest Activated: Perform 100,000 push-ups, run 1,000 km, perform 100,000 squats.

Ryo burst out laughing. This was exactly what he wanted.

He instantly teleported to a remote area of Korea, where he could train without attracting attention. He didn't just want to become stronger—he wanted to test the limits of this new System and see how far he could go.

Every movement he made resonated with overwhelming power. His muscles adapted, his endurance increased at an absurd rate, and he could already feel the immense difference between his old body and the one he now possessed.

But this was only the beginning.

Towards Total Domination

Ryo understood that Jin-Woo would gradually evolve until he became a Monarch, but he planned to get ahead. His training had no limits. Every day, he accumulated an absurd amount of experience and stats.

Finally, a new notification appeared:

DING! You have reached a level beyond the System's limits. You are now a Primordial Monarch.

Ryo smiled. He had surpassed both the Monarchs and the Rulers purely through physical strength, even before the war began.

His gaze shifted to Jin-Woo. His brother still had a long way to go, but Ryo knew one thing—when the time came, he would stand by his side, not just as an ally, but as an unstoppable force that would shape the future of this world.

The Ultimate Test

Eager to see the extent of his new abilities, Ryo opened a new interface within his System. An unprecedented option appeared:

DING! You can enter an Exclusive Dungeon of Unimaginable Difficulty. Warning: No turning back. Do you wish to enter?

Without hesitation, Ryo accepted. His body vanished in a flash of light, and he found himself in a nightmarish landscape. Towering creatures from another world, radiating an aura comparable to the Monarchs themselves, stood before him.

Ryo grinned. Finally, a real challenge.

He instantly activated his power, and the ground trembled under the weight of his presence. The battle began, and in an instant, the entire dungeon was plunged into absolute chaos.

An Important Encounter

After several hours of combat, Ryo reappeared in the real world, unscathed. His test had been successful—he was more than ready for this world.

However, he had no time to rest. An urgent call reached him. It was an official invitation from the Chairman of the Korean Hunters Association. He had been noticed.

Ryo smirked as he read the message.

"We need to talk. Come see me as soon as possible."

Things were about to get interesting.
