"Flying Thunder God Technique is already level 4..."
Jin sighed faintly.
Flying Thunder God was his main target for feeding traits to.
Although he hadn't managed to draw the corresponding Space-Time Ninjutsu, so he hadn't gained much experience, the sheer volume made up for it!
[Legendary Trait: Flying Thunder God Technique (Gold) lv4: Can teleport between objects marked with a Cursed Mark (400 meters). Each teleport costs 90 Chakra. Note: Marking an object costs 10,000 Chakra.]
400 meters!
More than ten times the original 30 meters!
If he marked all of Konoha with the Cursed Mark, then with his current Chakra reserves, he could truly teleport anywhere at any time!
At a thought, a small map gradually appeared before his eyes.
As it unfolded, it revealed the Konoha from the world of Naruto.
It was covered in densely packed green dots.
They occupied nearly every main road in Konoha, as well as most of the area along the Naka River.
And the Uchiha clan compound?
It was even more densely covered!
It practically glowed green!
The 10,000 Chakra it took to place a mark might seem like a lot, but to him, it was already insignificant.
"Big brother, are you a ninja?"
Just as Jin was pondering, the little Naruto, who had finished eating, suddenly looked up at him expectantly.
"Can you teach me how to train?"
"Teach you how to train?"
Jin blinked, a hint of scarlet suddenly appearing in his pitch-black eyes.
He was excited.
What was a four-year-old Naruto asking for a beating, if not this?
As expected of the Protagonist—even his requests were so thoughtful.
Jin had been worrying about how to defeat Naruto, and now he'd come right to him.
Jin smiled and held out his hand. "I can't teach you, but... we can try having a fight."
"Go ahead and give it your all. Don't worry about hurting me."
A fight?
At that, the little Naruto's eyes lit up even more.
Didn't all the stories say that fighting was the best training?
So after briefly taking a ready stance, he charged straight at Jin.
"Haha, watch out, big brother!"
He wasn't fast, but... he wasn't that slow, either.
To Jin, Naruto's movements were no different from slow motion.
Jin easily sidestepped, reached out with one hand to grab Naruto by the ankle, and tossed him away.
Thump.
The little brat hit the ground, but he didn't give up.
Instead, he charged back at Jin again.
He punched and kicked.
He clawed and bit.
At his young age, he had no idea how other people fought.
All he knew was that the cats and dogs in the woods fought like this.
So that was how he learned to fight, too.
Then he was tossed aside again.
[Uzumaki Naruto defeated. Attempting to copy trait.] [Copy successful. Congratulations, host, you have obtained the Legendary Trait Nine-Tails Jinchuriki (Gold).]
Jin: ?
???
Nine-Tails Jinchuriki!
This trait!
It was impossible not to covet it.
But... wasn't this sort of trait supposed to be impossible to copy?
Could a Nine-Tails really grow inside him, too?
"System, is this Nine-Tails Jinchuriki trait legit?"
[Legit.] [Nine-Tails Jinchuriki (Gold): Can borrow the power of the Nine-Tails. Current borrowable power: One-Tail.]
"So this Nine-Tails Jinchuriki trait only lets Naruto use as much power as he can handle at this stage?"
"Does that mean if I copy it again when Naruto's older, the same trait will be more powerful?"
Seeing the System's explanation, Jin suddenly understood.
So it was a kind of trait that could grow!
The only difference was that it kept the same name.
He nodded, suppressing his excitement, and focused on sparring with the little Naruto.
Naruto's parents had given him a tremendous gift the moment they met.
He'd have to remember this kindness.
Of course, the main reason was that the whole village was in turmoil over Cloud Village right now.
There weren't any spare forces to keep an eye on a blond brat and a chatterbox of a boy.
Time passed quickly.
Two-thirty in the morning.
The sky was frighteningly dark.
The moonlight, which had still shone faintly before, had long since disappeared behind the clouds.
Not a trace remained.
Jin looked at the boy in front of him and clicked his tongue in amazement.
"You actually wore yourself out. You're something else."
That was right. Naruto had passed out.
Of course, Jin hadn't knocked him out.
He'd simply exhausted himself until he collapsed.
Jin sighed and stood where he was, hesitating.
He should leave.
But he wasn't comfortable leaving the little Naruto here.
After a moment's hesitation, he finally picked Naruto up and carried him slowly toward the village.
Weak Presence, activate!
Swift Shadow, activate!
Dynamic Sensing, activate!
Byakugan, activate!
Three-Tomoe Sharingan, activate!
With these traits enhancing him, the area within a hundred meters was like a three-dimensional map to him.
It was all clearly laid out before his eyes.
Then he pushed off the ground and sped away.
Perhaps because of the time, or perhaps because of Cloud Village, the Anbu who usually seemed to be everywhere in the village were almost nowhere to be seen.
That made the little Naruto's trip home especially smooth.
As for the location?
He'd never been there, but Jin knew it like the back of his hand.
The distinctive two-story building looked completely out of place in its surroundings.
Ten minutes later.
Creak—
Jin pushed open the heavy wooden door.
Inside, clothes, shoes, and socks were strewn everywhere.
Expired milk covered the table, and boxes of instant noodles were piled against the wall.
There was a thick layer of them.
"Poor kid, no one's looking after him..." Jin sighed at the sight.
"Has nobody told this kid that you can't drink milk once it's expired?"
After saying that, he turned to look out the window. His voice suddenly grew quiet.
"Isn't that right, Kakashi?"
