Defeat, Power of the Nine-Tails!

"The Flying Thunder God Technique is already at level 4..."

Jin sighed softly.

The Flying Thunder God Technique was his main target for feeding.

Though he hadn't uncovered any corresponding Space-Time Ninjutsu and had little experience, the sheer volume made up for it.

[Legendary Trait: Flying Thunder God Technique (Gold) lv4: Allows instant teleportation between items marked with a Cursed Mark (400 meters). Each teleportation consumes 90 Chakra. Note: Placing a Cursed Mark consumes 10,000 Chakra.]

400 meters!

Compared to the initial 30 meters, that was more than a tenfold increase!

If he planted Cursed Marks all over Konoha, with his current Chakra reserves, he could truly teleport at will!

With a thought, a small map gradually appeared before his eyes.

When expanded, it was none other than the Hokage's Konoha Village.

On it, green dots were densely packed.

They covered almost all the main roads of Konoha and most of the area along the Naka River.

As for the Uchiha clan grounds?

They were impenetrable!

Practically glowing green!

The 10,000 Chakra cost seemed high, but to him, it was already negligible.

"Big brother, are you a ninja?"

Just as Jin was lost in thought, the little Naruto, now full from eating, suddenly looked up with anticipation.

"Can you teach me to train?"

"Teach you to train?"

Jin blinked, and a hint of crimson suddenly flickered in his dark pupils.

It was excitement.

This request from four-year-old Naruto—what was it if not asking for a beating?

As expected of the Protagonist, even his actions were so thoughtful.

Just when Jin was wondering how to beat Naruto, the kid delivered himself right to his doorstep.

Jin smiled and reached out a hand. "I don't know how to teach, but—we can try a fight."

"Go ahead, go all out. Don't worry about hurting me."

A fight?

Hearing this, Naruto's eyes lit up even more.

Didn't all the legends say fighting was the best training?

So after a simple starting stance, he charged straight in.

"Haha, watch out, big brother!"

His speed wasn't fast—but that was all it was: not fast.

In Jin's eyes, Naruto's movements were no different from slow motion.

He easily sidestepped, reached out with one hand to grab the kid's ankle, and tossed him away.

Thud.

The kid hit the ground like water, but he didn't give up.

Instead, he charged again immediately.

Punching and kicking.

Grabbing and biting.

At such a young age, the child didn't know how others fought.

All he knew was—the cats and dogs in the forest fought like this.

So he copied them.

And then he was thrown out again.

[Defeated Uzumaki Naruto. Attempting to copy trait.]

[Copy successful. Congratulations, host, you have obtained the Legendary Trait: Nine-Tails Jinchuriki (Gold).]

Jin: ?

???

Nine-Tails Jinchuriki!

That trait!

It would be a lie to say he wasn't tempted.

But... this kind of trait should be the non-replicable type, right?

Could it be that his body could also grow a Nine-Tails inside him?

"System, is this Nine-Tails Jinchuriki trait authentic?"

[Authentic.]

[Nine-Tails Jinchuriki (Gold): Allows borrowing the power of the Nine-Tails. Current borrowable power: One-Tail.]

"So this Nine-Tails Jinchuriki is just the maximum power Naruto can handle at this stage?"

"Does that mean if I copy it again when Naruto grows up, the trait's power will be different?"

Seeing the system's explanation, Jin suddenly understood.

Wasn't this basically a type of growable trait!

The only difference was that the name stayed the same.

He nodded, suppressing the joy inside, and turned his attention back to sparring seriously with little Naruto.

This kid's parents had given him a huge gift the moment they met.

He had to remember this favor.

Of course, the main reason was that the village was currently in chaos because of Cloud Village.

They didn't have the spare power to pay attention to a yellow-haired brat and a chatterbox kid.

Time passed quickly.

Two-thirty in the morning.

The sky had turned terrifyingly dark.

The moonlight, which had once held some luster, had now completely shrunk into the clouds.

Not a trace remained.

Jin, looking at the boy in front of him, clicked his tongue in surprise.

"You actually exhausted yourself to the point of collapse. You're something else."

That's right, Naruto had already passed out by now.

Of course, it wasn't from being knocked out.

He had simply drained his stamina dry and collapsed from exhaustion.

Jin sighed, standing there hesitating.

He should leave.

But leaving little Naruto here alone made him uneasy.

After a moment's hesitation, he finally hoisted the kid onto his back and slowly walked toward the village.

Weak Presence, activate!

Swift Shadow, activate!

Dynamic Sensing, activate!

Byakugan, activate!

Three-Tomoe Sharingan, activate!

With these traits active, the area within a hundred meters was like a three-dimensional map to him.

Clear as day before his eyes.

Then, with a single step, he shot off at high speed.

Perhaps because of the time, or maybe because of Cloud Village, the Anbu that were usually everywhere in the village were now almost nonexistent.

This made little Naruto's trip home exceptionally smooth.

As for the location?

Even though he'd never been there, Jin had already memorized it thoroughly.

That peculiar two-story building stood out starkly from the surrounding world.

Ten minutes later.

Creak—

Jin pushed open the heavy wooden door.

Inside, clothes, shoes, and socks were strewn everywhere.

The table was covered in expired milk, and the walls were piled high with instant noodle cups.

A thick layer of them.

"Sigh... a kid with no one to look after him..." Seeing this, Jin let out a sigh.

"Why didn't anyone tell this kid that milk can't be drunk once it's expired?"

He turned to look out the window, his voice suddenly dropping low.

"Don't you think so, Kakashi?"
