I Transmigrated to the Shinobi World, and You Give Me a Game Development System?

Ding~ System loading 100%, activation initiated.

On the night of June 17th, in the 46th year of Konoha, Kai, a young Chūnin of Konoha, felt his heart tremble once, twice, and then thrice with excitement.

A wave of overwhelming joy surged through him, nearly bringing him to tears. After 18 years of living in the Naruto world, and still being just a Chūnin, Kai was overjoyed.

Finally!

After so many years, the cheat every transmigrator dreams of had finally arrived.

At this moment, all the hardship Kai had endured seemed to melt away.

After all, in the Naruto world—a brutal place where bloodline and cheats determined one's fate—Kai, despite being a member of the prestigious Uchiha clan, was merely a branch member. Worse, his mother was a common civilian of Konoha, which made his bloodline "impure" within the Uchiha clan.

This wasn't an exaggeration or some cliché rivalry between legitimate and illegitimate offspring. It was simply because his Uchiha blood wasn't pure enough, and thus, his talent was obviously trash.

Normally, such Uchiha would avoid becoming ninjas and instead work as the clan's "lower class," managing the Uchiha family business.

However, Kai, being a transmigrator, was keenly aware of how dangerous the Shinobi world was. He knew that the Uchiha clan would face an extinction crisis in the future.

So, since childhood, Kai worked hard, even though everyone in the clan—whether elders or outsiders—thought he had little talent and no future as a ninja. He still trained tirelessly, hoping to become strong through sheer hard work, much like the legendary Blue Beast of Konoha who almost ended the story with a single kick.

But reality proved Kai wrong.

Might Guy became the King of Taijutsu because he was a genius in that field. Kai, on the other hand, was utterly mediocre. No matter how hard he tried, his efforts only led to injuries from overtraining.

When he tore a ligament, Kai finally realized: the Shinobi world is a harsh and realistic place. Without a cheat or an ultimate bloodline, no amount of effort would save you from mediocrity.

The cursed Otsutsuki clan had polluted the genetics of the Shinobi world, turning it into a true caste system where bloodline determined everything.

And now, on the brink of the Third Great Ninja War, Kai had come to terms with reality. He planned to fake his death during the war and flee from Konoha, living out the rest of his life in another country under a different name. But just when he had given up hope on ever getting a cheat, it finally appeared.

It really was true: the heavens never completely close a door on you.

At this moment, Kai realized that his time had come!

So, system, prepare to level me up—Kai was so overwhelmed with excitement that his thoughts started to wander.

Ding~ Super Game Developer System successfully activated. Please begin developing your first game. Beginner's pack: Game Development Mastery skill has been granted.

Suddenly, a vast amount of knowledge surged into Kai's mind, leaving him with the strange sensation of being overwhelmed by information.

But then…

"... System, say that again. What kind of system are you, and what's your function?" Kai asked, his face expressionless. His earlier excitement was completely gone.

System: Super Game Developer System. The function is to cultivate the host into the world's strongest game developer.

Kai: "...What world am I in right now?"

System: Earth, in the year 2024.

Kai: "...?? This is the Shinobi World, Year 47 of Konoha!!!"

System: Scanning complete. This is Earth in the year 2024. Please complete your first game as soon as possible.

Kai: "??? You @#￥%…"

At that moment, Kai couldn't help but curse.

He had thought he got a system that would make him OP, but instead, it was a system from some modern Earth drama. This was a scam of the highest order.

To make matters worse, the system seemed intelligent but was actually an AI idiot that couldn't even recognize the world it was in.

It turned out that dreaming of becoming an OP protagonist with a cheat system was just wishful thinking. It was better to continue preparing to flee from Konoha.

After all, his father had died on duty, and his mother had passed away when he was young, so Kai had no family left in Konoha.

Although his Uchiha clanmates often looked down on him, thinking that his lack of talent was a disgrace to the clan, they hadn't directly bullied him due to the pride that most Uchiha carried. His situation was somewhat similar to Obito's, being called a "disgrace to the Uchiha," but without the outright harassment.

Living in such a cold environment for 18 years, Kai had little sense of belonging to Konoha, so running away didn't seem like a big deal to him.

Run, run, run—if you run fast enough, the Shinobi world is big enough for anyone to find a new home!

Of course, the actual escape would have to wait for two more years. For now, Kai needed to lie low in the village, avoiding suspicion. After all, with his sensitive identity as an Uchiha, trying to escape Konoha would be nearly suicidal.

So, feeling bored while lying in bed, and unable to sleep after the system's activation, Kai decided to study the system a bit.

But every time he called upon the system, it responded in a robotic, rigid manner, far less useful than modern AI assistants. All it ever said was to finish developing his first game as a beginner's task.

High EQ version: The system is unwavering in its mission to help the host become a top-tier game developer, unlike certain other systems that scheme and manipulate their hosts.

Low EQ version: The system is a low-level AI idiot!

Damn, in this backward world with no computers or game consoles, where was he supposed to make a game?

Cursing the system in his heart, Kai still decided to study the "Game Development Mastery" skill etched into his brain. He just wanted to pass the time.

But soon, he realized something was off. His eyes widened in shock.

"Is this… game development skill? What kind of abstract game-making technology is this?"

He couldn't help but complain. The system's game development skill was highly abstract, or more precisely, too advanced.

In addition to the platforms Kai knew—like computers, consoles, and mobile phones—it also included virtual reality, artificial intelligence, and even neural networks. The skill covered platforms that didn't even exist yet on Earth, let alone the Shinobi world.

Kai thought that with this skill set, he could easily find work even in the year 2424 on Earth.

But sadly, this was the Shinobi world, where such advanced technologies were far too ahead of their time.

Wait a minute… What's this about neural networks? Future humans could use brain cells and thoughts like computers and even connect with each other through mental resonance to form a neural network?

What the hell kind of hardcore sci-fi tech was this? It felt more like something from a fantasy story.

As he mentally sifted through the related knowledge, Kai was amazed.

Then, a thought struck him.

The Shinobi world, in many ways, was a magical place. And techniques involving the mind weren't rare here.

In fact, as an Uchiha, Kai was well aware of such things.

After all, the Uchiha clan possessed the Sharingan, known as the "Eye that Reflects the Heart." The Sharingan was directly linked to a person's mind, and once it evolved into the Mangekyō Sharingan, it could grant extraordinary abilities based on the user's deepest desires.

In a way, the Sharingan itself was a tool for mental manipulation.

So the question was: could he use the Sharingan or other mental techniques to develop and play games using the skills from the system?

As this thought crossed his mind, Kai fell into deep contemplation.

The more he thought about it, the more he compared it to the Sharingan's capabilities, and the more feasible the idea seemed.

"Should I… give it a try?"

Muttering to himself, Kai felt a surge of excitement. Without further hesitation, he decided to go for it.

Right then and there, Kai activated his Sharingan.

Although he was considered mediocre within the Uchiha clan, as an 18-year-old Chūnin, opening his Sharingan was no problem, even if it was just a single tomoe, which was quite embarrassing for a transmigrator.

Kai closed his eyes and focused his mind on his Sharingan, using it as a "platform." He combined this with the illusion techniques unique to the Shinobi world, and, following the system's game development skills, he attempted to create a game.

And surprisingly, it worked. In his mental vision, the tools and elements needed for developing a game in a neural network system appeared.

Everything came together naturally

, as if it was supposed to happen.

But this success wasn't a miracle; it was the result of Kai's hard work over the years.

As a mediocre Uchiha, Kai knew he lacked talent, so he focused on intense training, honing specific skills to make up for his shortcomings.

For example, he had refined his chakra control and his mental focus—areas that most Uchiha didn't need to train because their Sharingan would compensate for them.

It was only because of this meticulous training that Kai could now achieve something so extraordinary.

Hard work does pay off, but only if you get the right opportunity and platform.

And now, Kai seemed to have found the platform and opportunity he had been waiting for all these years.

However, the fact that this opportunity came in the form of making games felt like some dark cosmic joke.

After all, no matter how good a game developer he became, could it really turn him into a Kage-level powerhouse?
