Myriad Worlds Mercenary System

In the first testing room of the Konoha Ninja Academy, a black-haired boy dressed in clothing bearing the Uchiha Clan's gunbai crest walked in slowly.

A Chunin proctor wearing a headband glanced at the clipboard in his hands, checked the candidate's information, and explained the assessment criteria to the black-haired boy.

"The graduation assessment consists of the Three Techniques. The Clone Technique requires you to create four clones, the Substitution Technique requires you to use the substitution log on the floor to the right to activate it, and the Transformation Technique requires you to transform into my appearance. Did you understand?"

"Understood."

The black-haired boy replied, and before anyone could see his hands move, a 'poof' sound echoed as five identical boys appeared on the field. Then, the Substitution Technique activated-the boy in the center vanished on the spot, instantly appearing on the right where the substitution log had been placed. Finally, amidst another burst of smoke, the headband-wearing proctor appeared in the arena.

"The Three Techniques pass. Congratulations on passing the assessment."

The proctor looked at the scene in the arena with satisfaction, stamped the assessment form with the mark of approval, and handed the Konoha Forehead Protector he had set aside to the black-haired boy who had released the Transformation Technique.

The black-haired boy was named Kazuhiko Uchiha, a ninja from the Uchiha Clan, one of the two major noble clans of Konoha. Today, he had participated in the Ninja Academy's unified graduation exam alongside dozens of students and successfully passed the assessment.

Taking the Forehead Protector with a blank expression, Kazuhiko Uchiha tied it around his forehead like the vast majority of ninjas.

Leaving the Ninja Academy without looking back, Kazuhiko Uchiha completed the graduation procedures according to village regulations, registered his name, and officially became a Genin of Konoha.

In the evening, Kazuhiko Uchiha returned to his empty home, closed the door, and looked at the electronic calendar on the wall displaying "March 1, Konoha Year 55," feeling a growing bitterness in his heart.

Sigh, there's only a little over a year left. I really am so unlucky. With so many ninja clans in Konoha, why did I just have to become a member of the Uchiha Clan?

The reason Kazuhiko Uchiha sighed and complained was naturally because of the upcoming Uchiha Clan Massacre a year later. As a legitimate member of the Uchiha Clan, he would inevitably become a target for elimination.

As for why Kazuhiko Uchiha knew about events a year in the future, it was because he was a transmigrator.

Two months ago, he was just a very ordinary office worker on Earth. For some unknown reason, after waking up from sleep, he had transmigrated to the Naruto World and even become a boy named Kazuhiko Uchiha.

As Naruto was one of the most popular anime of his past life, Kazuhiko Uchiha had watched it for a long time outside of work and still had vivid memories of major events that occurred in the original story. Once he calmed down, he remembered this matter concerning his own safety.

Consequently, Kazuhiko Uchiha began reviewing the original owner's memories, only to discover something that left him even more helpless.

The original owner was twelve years old, and his parents had long since died on missions. Although he was a classmate of Uchiha Itachi in the same year at the Ninja Academy, the gap between the two was like fireflies compared to the bright moon, completely incomparable.

The immensely talented Uchiha Itachi had graduated from the Ninja Academy in just one year, become a Chunin at age ten, and not long ago, awakened the Mangekyō Sharingan due to Shisui's death, becoming a powerful Kage Level ninja.

As for the original owner-who possessed poor aptitude and was overly playful-he had messed around in the Ninja Academy for six years and had still not managed to graduate by the time Kazuhiko Uchiha transmigrated.

For the sake of his own little life, the post-transmigration Kazuhiko Uchiha began to double his efforts in practicing Taijutsu, the basic Three Techniques, and the slightly more advanced C-Rank Fire Release Ninjutsu: Great Fireball Technique.

A week later, Kazuhiko Uchiha mastered the most basic Taijutsu and Ninja Tool Throwing Technique.

Two weeks later, Kazuhiko Uchiha could proficiently use the Three Techniques, reaching a level where he could use them without hand seals.

A month later, Kazuhiko Uchiha completely mastered C-Rank Fire Release Ninjutsu: Great Fireball Technique, and could release great fireballs of varying power by adjusting his chakra output.

Having mastered all of his current abilities, Kazuhiko Uchiha submitted a graduation application to his homeroom teacher without hesitation, unwilling to continue wasting precious time in the Ninja Academy. He wanted to rapidly improve his strength through real combat and fight with all his might for a sliver of survival.

Forget it, I won't dwell on these useless thoughts. I'll start training according to plan.

Kazuhiko Uchiha took a deep breath, stopped indulging in useless complaints, and sat cross-legged to refine chakra.

Perhaps due to the soul fusion after transmigration, Kazuhiko Uchiha's mental energy was vastly superior to the original owner's. He handled chakra refinement with ease, and in a mere two months, raised his chakra volume to the peak of the Genin level.

Tonight, Kazuhiko Uchiha prepared to continue refining chakra, striving to push further and elevate his chakra volume to the Chunin level.

An hour later, a fresh wave of energy surged from Kazuhiko Uchiha's fatigued body, which had been exhausted by chakra extraction. A purer and denser chakra appeared within his body.

Haha, I've finally reached Chunin. That way, my strength has increased by another twenty percent, and I'll be able to use the great fireball a few more times.

Kazuhiko Uchiha opened his eyes, wiped away the sweat on his forehead, stood up with excitement, and prepared to rest for a moment before making a lavish dinner to reward himself.

Oh no! My chakra!

Suddenly, Kazuhiko Uchiha felt the full chakra within his meridians break free from his control. Under the manipulation of an inexplicable force, it rushed toward his brain in a torrent, then vanished into an unknown realm deep within the mind.

What's going on? Where did my chakra go? Could it be that I'm about to awaken my eyes? But that doesn't seem right either-if the Sharingan were awakening, the chakra should rush toward my eyes instead.

Just as Kazuhiko Uchiha was filled with confusion and unsure of what to do, a mechanical voice suddenly rang out in his mind.

"Energy replenishment complete... System self-diagnostic procedure initiating..."

"Self-diagnosis complete, system integrity 100%. Host detected... System fusion initiating..."

"Fusion progress 5%... 10%... 50%... 90%... 100%..."

"System binding successful. Myriad Worlds Mercenary System officially activated..."

"Tip: Mentally call the system to enter the system interface. Finally, I wish you a pleasant user experience."

The mechanical voice fell silent after speaking. Once Kazuhiko Uchiha recovered his wits, a long-lost smile emerged on his previously cold face, and he laughed excitedly, "Hahaha, it seems my luck isn't too terrible after all. I've finally waited for my Golden Finger."

Having been influenced by web novels in his past life, Kazuhiko Uchiha was not unfamiliar with such fortuitous encounters as acquiring a system, a Golden Finger, or an old grandfather upon transmigration, and accepted it very easily.

Following the prompt of the mechanical voice, Kazuhiko Uchiha mentally chanted "System" in his mind to activate his Golden Finger.
