Naruto: They Have a System by Carefree Coder
Synopsis:
Uchiha In transmigrated, arriving in the Uchiha Clan, and also obtained the Strongest Protagonist System.
However, what puzzled Uchiha In was that after the System improved Uchiha In's body, it disappeared without a trace.
What Uchiha In didn't know was that everything around him had undergone tremendous changes; the female protagonists and supporting female characters of the Naruto World had all received Systems!
Tsunade obtained the Strongest Healer System, activating the sole main mission: become In's wife.
Mikoto obtained the Strongest Brother-Con System, activating the sole main mission: become In's bride.
Mei Terumī obtained the Strongest Mizukage System, activating the sole main mission: become In's lover.
...
Hinata listened to the voice of the Strongest Adopted Daughter System in her mind, her face turning red, her pupils spinning, and white mist rising from her head...
Chapter 1: Transmigration to the Uchiha
"The most basic thing for a Ninja is to Cultivate Chakra. Only those who can Cultivate Chakra can be considered to have initially stepped into the threshold of a Ninja."
"You all learned to Cultivate Chakra last year and have all successfully done so, which means you all have the potential to become Ninja."
"Today, I will teach you the three most basic Ninjutsu, which are also the most widely used Ninjutsu in future battles."
"Those are the Three Body Technique, specifically the Transformation Technique, Clone Technique, and Substitution Technique."
Inside the Ninja Academy, Konoha Village, Naruto World, in the middle-grade Class 1.
At this moment, the Chunin teacher of the middle-grade Class 1 stood on the podium with a textbook, lecturing the 27 students below.
It was now time to teach the most important and fundamental Three Body Technique for Ninja, and everyone below was listening attentively, eagerly absorbing the knowledge taught by the teacher.
And Uchiha In was one of them.
However, sitting by the window, after he finished listening to the outline of the Substitution Technique, he didn't listen to the outlines of the Clone Technique and Transformation Technique.
The Substitution Technique indeed had great use in combat, becoming first-rate at dodging skills once mastered, while the Clone Technique and Transformation Technique were far inferior; there was no need to master them, just being able to use them roughly was enough.
This was Uchiha In's inner thought.
"I never thought I would have a day when I Transmigrate to Naruto."
Uchiha In sat by the window, sighing occasionally.
Uchiha In knew that he might never be able to return to his original world.
That's right, he was a Transmigrator.
He Transmigrated into a background character of the Uchiha Clan, who had no mention in the original work and likely died before the original story even began.
No, it should be said that he definitely died, because in Uchiha In's original body's memory, he also had a cousin named Uchiha Mikoto, who had only graduated from the Ninja Academy last year.
And Uchiha Mikoto had a younger cousin? There was absolutely no information, he had never even heard of it. He probably died in the Second Shinobi World War or the Third Shinobi World War, right?
Upon thinking of this, Uchiha In's heart became very complicated, and upon thinking of his System, his heart became even more complicated.
When he first Transmigrated, Uchiha In obtained the Strongest Protagonist System, and this System was kind enough to help him cleanse his marrow and improve his body, and then... there was no 'then'.
The System seemed to have fallen into a deep sleep; no matter how Uchiha In called out, there was no reaction at all, as if it had disappeared.
They all say that the most awesome thing about a Transmigrator is the System, so why did I encounter such a useless System!
"Forget it, I'm not going to do anything anyway. When the Uchiha Clan is about to be annihilated, I'll find an excuse to leave for half a year a month before, and then nothing should happen, right?"
"After all, Naruto has already ended. Even if I don't do anything, I should be able to live until the end."
Uchiha In was a very troublesome person, so when he knew that this world was the Naruto World, he didn't have the idea of saving the world like Naruto. He just wanted to quietly be a handsome man, find a beautiful wife, and live a simple and happy life.
Of course, it would be even better if he could have multiple beautiful wives.
As for the dangerous things in the original work, Uchiha In wanted to say, the farther you are, the farther you should get away from me.
Of course, in the absence of danger, Uchiha In also wanted to see what his arrival would change in the Naruto World.
A week's time was enough for Uchiha In to understand what period the current Naruto was in.
If he wasn't mistaken, the Second Shinobi World War should have already begun, or was about to begin.
Although Uchiha In didn't have the idea of saving the world, he absolutely would not neglect his own Cultivation.
Although Uchiha In would not actively seek trouble, he was also afraid of trouble finding him, so he naturally needed the ability to protect himself.
Although Uchiha In's System seemed to have no reaction, it did improve Uchiha In's body after all.
With his body improved, Uchiha In's Chakra volume greatly increased, his hand seal speed became faster, and most importantly, Uchiha In also awakened his Sharingan, and it was a two-tomoe Sharingan upon awakening.
This also gave Uchiha In a shred of self-preservation in this Naruto World.
After all, at this age, not many people could awaken the Sharingan, let alone a two-tomoe Sharingan?
Of course, compared to those Chunin and Jonin, Uchiha In did not yet have such powerful strength, but within the Ninja Academy, he was already in the realm of invincibility.
However, Uchiha In did not directly reveal his talent now, as he knew that the tallest tree catches the most wind.
Not to mention Danzo and the Senju Clan, who were coveting the Uchiha Clan, even the internal affairs of the Uchiha Clan were not very harmonious.
If Uchiha In were to display his talent, the position of the Uchiha Clan Chief's son would be threatened, and it was likely that Uchiha In would be the one to suffer in the end.
Chapter 2: Confession from Kushina
Ring-ring-ring ~
After the break time was over, it was time for class again.
At this moment, the homeroom teacher walked towards the podium with an unfamiliar student.
A delicate face, beautiful red long hair softly draped over her shoulders, fluttering eyelashes, and below them, a pair of large eyes like magnificent black gemstones, with soft, pink lips gently pursed.
This was none other than the protagonist's mother from the original work, Uzumaki Kushina.
At this time, she was just an 8 or 9-year-old loli, but even as an 8 or 9-year-old loli, Uzumaki Kushina possessed a charm that others found hard to match.
However, Uzumaki Kushina's face showed unease, and her expression carried a hint of restraint. In Uchiha In's view, the current Uzumaki Kushina was clearly a little unaccustomed to having just arrived in Konoha.
"Alright, everyone quiet down. Today, a new friend is joining our class. Let's give them a warm welcome."
As the teacher's voice rang out, warm applause erupted in the classroom.
Minato Namikaze sat in the front row, and upon seeing Uzumaki Kushina, his eyes lit up, and he clapped even more vigorously.
"Let's hear our new classmate's self-introduction."
The teacher made the students stop clapping, and then asked Uzumaki Kushina to introduce herself.
