Naruto: Reborn as Uchiha Obito

To the south of the Land of Water, it was still that same cave.

The cave along with the entire interior of the mountain and one basement had been completely hollowed out and turned into a secret base.

Under Uchiha Obito's orders, the White Zetsu had already completed the renovations. The inside now featured proper ventilation, multiple rooms, labs, training grounds, and even dungeons.

As for the furniture, equipment, and other supplies? Naturally, they were all "acquired" from the Land of Water.

After all, the Land of Water was a great nation. Wouldn't it be strange if a massive country occasionally lost a few resources?

And with the Mist's Mizukage himself helping Obito cover things up, it wasn't really a problem at all.

In short, the base was heavily inspired by Orochimaru's approach.

Obito didn't need to set up hideouts all across the world like that snake bastard. One solid, fully functional base was more than enough.

After all, his old hideout in the Land of Grass was nothing more than a giant underground pit.

So Obito decided: from now on, that one would be "Base 1." This new one in the Land of Water? "Base 2."

On this day, inside the base, Obito was reading a ninjutsu scroll from Konoha in the study.

The room had rows of bookshelves lined with scrolls looted from the Leaf. Only the Scroll of Seals and some particularly special ones were stored in Kamui space.

"I see... so to learn the Flying Thunder God technique, you not only need space talent and spatial awareness, but also a certain level of sealing proficiency..."

Obito studied the notes on the Hiraishin and muttered to himself.

At that moment, a purple figure suddenly burst into the room.

"Hey, big pervert, I've mastered that move! Teach me a new sword technique already!"

After bringing back Yugao Uzuki, Obito had selected a few original sword techniques and began training her.

Half a month ago, after the base's construction was completed, Obito made a solo trip to the Land of Iron.

Using Kamui, he looted all their copper, iron, and chakra-infused metals... then grabbed their swordsmanship scrolls while he was at it.

After returning, he began teaching Yugao the sword style of the Land of Iron.

As for the Konoha-ryu sword technique? That required a much higher threshold—proficiency in shadow clones, shunshin, genjutsu, and more.

For now, starting with the Iron Country's style was just right for her.

"..."

Obito put down the scroll and sighed.

"You're supposed to call me 'Madara-sama.' Is that how you ask for training?"

"Hmph! You're not Madara Uchiha at all."

Yugao crossed her arms and looked at him like she was seeing through a scam.

"Oh? And what makes you so sure I'm not?"

Obito raised an eyebrow, intrigued.

"Your voice... it's way too young. And your skin... what kind of old man has skin that smooth?"

"Don't treat me like I'm stupid!"

She pointed at his neck and hands with absolute confidence.

"Tch~ That's your reasoning? You've never heard of ninjutsu that keeps you young?"

"...Eh? There's really a technique like that? You're not lying to me, right?"

Yugao blinked, suddenly thrown off.

"Heh. Tsunade-hime from Konoha—she's nearly forty, and still looks twenty."

As he spoke, Obito gave her a glance.

"Of course, you're just a little girl. No way you'd know about that."

Yugao Uzuki was just a student who hadn't even graduated from the Academy. Her family wasn't from any major clan either. No access to Tsunade-level intel, totally normal.

"You...!"

Yugao gritted her teeth.

"So you really are Madara Uchiha?!"

"What do you think?"

Obito replied ambiguously, staring down at her with a teasing grin.

"Hmph!"

"Even if you do have some youth-preserving jutsu, there's no way you're really Madara Uchiha!"

Yugao stood her ground.

"Oh, and what is the basis this time?"

Obito raised an eyebrow.

"Madara Uchiha is a legendary man who could fight the First Hokage. How could he be a pervert like you?!"

"If you really are him, take off your mask and prove it!"

Yugao Uzuki stared at his mask, determined.

"..."

Two sentences.

And Obito was absolutely silenced.

'Did I just get roasted by a little girl? She cooked me—no... she violated me.'

'Thank fuck I'm the only one who knows this... if anyone else saw that, I'd be a damn meme.' Obito Uchiha thought, feeling a dark comfort in solitude.

This little kid is quite smart.

Then, he chuckled:

"Oh, childish agitation. No matter what, you have to call me 'Madara-sama'."

"Tch, I won't."

"Hmm... Actually, 'master' has a better ring to it."

"Pervert, don't even think about it!"

"Ahem... Yugao, you don't want me to kill him... do you?"

Obito unleashed his ultimate move.

"Bastard!"

Yugao Uzuki jumped to her feet instantly.

Looking at her angry face, Obito smiled happily. Today's happiness... get!

And today's biggest loser? Hayate Gekkō. F in the chat.

"Alright, let's get down to business."

After laughing for a while, Obito took out a chakra test paper and handed it to Yugao Uzuki.

"Here. Test your chakra attributes first."

Yugao Uzuki huffed, grabbed the paper, and infused it with chakra.

She watched as the strip burned instantly.

"Is it only fire attribute...?"

Obito nodded, then pulled out a box from the Kamui space.

After opening the box, revealing rows of Red items inside, he thought for a second, then picked one and handed it to Yugao Uzuki.

"Swallow it."

"What is this? It can't be poison, right?"

Yugao Uzuki looked curiously at the blood-red item in her hand. The color looked a little evil.

"Relax. If I wanted to kill you, poison would be overkill."

Obito rolled his eyes.

"Hmph~"

Still skeptical, she swallowed it in one go.

Obito moved behind her and began to help her absorb it.

"Ah!!h"

A while later, the process was done, and Obito dropped back into his chair.

"How's it going? How do you feel?"

"Bastard! You didn't say it would hurt that much!"

Yugao Uzuki was panting on the floor, glaring through gritted teeth.

After that, she stood up and stretched.

"I feel like I'm more powerful... and my body's more relaxed."

"What was that thing?"

She asked curiously.

"Of course it's a good thing. Well, try again."

Obito handed her another chakra test strip.

She took it and injected chakra again.

"Wind, water, fire. That's okay."

Obito nodded. The Red item he used for her was made from an ordinary Jonin ninja with no Kekkei Genkai, one of the Mist team he'd destroyed before.

"It's amazing!"

Yugao Uzuki looked at the test strip on the ground in awe, it had been sliced in the middle, soaked on one end, and burning on the other.

"Hmph, follow me. Power is the easiest thing to obtain."

Obito stood up and walked toward the door.

"Come on. Didn't you want me to teach you swordsmanship?"
