"Is this what you've been using to train?"
After looking over the items Uchiha Chen had brought out, Uchiha Shisui was somewhat surprised.
After all, while those notes were indeed useful, they were nothing more than simple introductions.
"Yeah, if there's anything I don't understand, I ask Izumi, but most of it is just me figuring things out on my own.
I've been practicing ninjutsu lately, but I haven't succeeded yet. Otherwise, I'd be more confident about challenging Big Brother Shisui and Big Brother Itachi."
He had obtained the Great Fireball technique through the system, but if he used it all of a sudden, it would inevitably arouse suspicion.
By claiming he was currently researching it, it wouldn't seem so suspicious when he successfully used it later.
"You're practicing ninjutsu? What is your chakra nature?"
Hearing that Uchiha Chen was practicing ninjutsu, Uchiha Shisui asked.
It was only then that Uchiha Chen realized he had never actually tested his own chakra nature.
He had to admit, this was a significant oversight.
Seeing Uchiha Chen's expression, Uchiha Shisui guessed that he didn't know about chakra natures.
And so, while taking out a piece of chakra test paper, he began to explain the concept of natures.
Earth, water, fire, wind, and lightning—all five natures could be tested with the paper. Generally, a person is born with one, and through hard work, they can develop two or three.
Uchiha Chen took the chakra test paper and channeled his chakra into it.
As the chakra flowed in, the paper first split in two, and then one half burst into flames while the other wrinkled.
"Wind, fire, and lightning?"
Uchiha Shisui looked astonished. Even most jonin usually only possess two natures.
Even Uchiha Shisui himself, as an adult, only had four: wind, fire, lightning, and yin.
Because of this, just based on the number of natures he possessed, Uchiha Chen was undoubtedly a genius.
At the same time, Uchiha Shisui dismissed the possibility that Uchiha Chen was a spy.
After all, someone born with three natures would, barring any accidents, inevitably grow into a jonin—and a very powerful one at that.
Not to mention that other villages wouldn't be willing to send such a genius into enemy territory, even Konoha today didn't have the audacity to do so.
After all, the appearance of a genius was something every village dreamed of but rarely found.
"I didn't expect you to have three natures, and they are all clearly offensive ones.
Chen, may I call you that?"
"Of course, Big Brother Shisui."
"Don't tell anyone about your three natures, not even Izumi.
Being too dazzling makes it easy to attract jealousy. If anyone asks, just tell them you have the fire nature."
As he spoke, Uchiha Shisui took out a scroll.
"This contains the Great Fireball technique, along with some of my own insights, and I've also recorded some notes on chakra refinement. Just follow this for now.
If there's anything you don't understand, you can ask me or find Itachi."
Setting aside the issue of his identity, Uchiha Shisui actually quite liked this daring and driven little guy, Uchiha Chen.
Now that his identity was confirmed, Uchiha Shisui's only hostility vanished.
"Thank you, Big Brother Shisui."
Uchiha Chen took the scroll, secretly resolving in his heart that he would definitely save Shisui and the others during the Uchiha clan massacre in a few years.
"Alright, you go ahead and train. I have some things to attend to."
"Wait, Big Brother Shisui."
"What is it?"
Hearing Chen call out to him, Shisui was a bit puzzled.
"Big Brother Shisui, don't go looking for Big Brother Itachi just yet. Let Big Brother Itachi and Izumi spend some time together."
Hearing this, Shisui was slightly stunned, then nodded with a smile.
"Understood, you little rascal."
After Shisui left, Uchiha Chen let out a long sigh of relief.
The disappearance of the other party's hostility was clearly a good thing.
With no one else around, Uchiha Chen opened his system panel.
Host: Uchiha Chen Age: 4 (18) Abilities: Ninjutsu: Body Flicker Technique LV1, Great Fireball Technique LV1. Taijutsu: Basic Taijutsu LV1.
Genjutsu: XXXXX.
"Damn it, System, what's with the mosaics on the Genjutsu? What kind of system keeps popping up with mosaics for no reason? Are you trying to become the world's number one censorship system?"
Uchiha Chen was truly speechless at the sight of the mosaics. It was a good thing that the attribute panel had become more detailed, but what the hell were these mosaics?
"I feel like it, bite me if you're unhappy."
The System's voice was incredibly smug. If he could actually hit the System, Uchiha Chen swore he would give this unscrupulous, infuriating system a sound thrashing.
"What's the deal with the levels?"
Uchiha Chen didn't want to continue the topic of the mosaics; he felt like he would be angered to death if he kept asking.
"It's very simple. The lower the level, the lower the effectiveness of the Ninjutsu, Genjutsu, and Taijutsu. LV1 just means you've barely learned it.
In this world of Naruto, the abilities of the vast majority of people are actually just LV1. Only a few exceptional powerhouses have different levels."
"So, it's like how Second Pillar's Great Fireball can only burn wooden stakes, while Madara can suppress the Allied Shinobi Forces?"
"That's pretty much the meaning. Taking Fire Release as an example, the level affects the attack range, temperature, and certain shape transformations of the Fire Release. So, work hard to level up."
"Then how do I level up?"
"With this System here, you just need to use them frequently to increase your proficiency."
Hearing this, Uchiha Chen thought this infuriating system had finally found its conscience, but upon closer inspection, he discovered the proficiency was at 0/1000.
In other words, to go from LV1 to LV2, he would need to use the Great Fireball at least one thousand times.
He knew that at higher levels, relying solely on usage counts to level up would probably take until his next life.
"Besides proficiency, is there any other way?"
"Apart from frequent use, there is researching the Ninjutsu itself. If you can develop a higher-tier Ninjutsu, the lower-tier ones will gain a lot of experience points.
Additionally, you can also level up by completing missions."
Uchiha Chen could naturally understand the previous points, but as the last one was mentioned, a bad feeling followed.
"I refuse!
You're definitely thinking of ways to screw me over!"
"How could such an understanding system as myself think of screwing someone over?
That is blatant slander, so I have decided to increase the difficulty of your missions."
"Screw you!"
"Say that again? Do you believe I'll issue a mission to kill Danzo right now?"
"You..."
Uchiha Chen was utterly speechless. What kind of system was this infuriating? What kind of sin had he committed to encounter such a speechless system?
"Ding, System notification, Hunting Mission initiated, mission target..."
