Naruto: The dungeon I developed went viral throughout the entire ninja world.

Chapter 1: The Countdown to the Last 3 Days

Konoha 55th year.

The Illusionary Dojo has been open for half a month, but its turnover is zero, and business is extremely poor.

Roy sat behind the counter.

Three days later, the Uchiha clan will be completely wiped out, leaving only one survivor.

This has nothing to do with him. Roy is a time traveler, and surviving in this world is his only thought.

Suddenly, a panel that only he could see popped up in front of him.

[God-tier dungeon system activated.]

[Bound Host: Roy.]

[New player task: Greet the first customer.]

[Task Reward: One-time granting access to livestream across the entire village.]

Roy glanced at the panel and realized that he also had a system.

Live streaming permissions are a very interesting thing; they're a real tool for causing trouble.

Roy stood up, preparing to stretch his neck.

Just then, footsteps came from outside the door. Roy looked out the window and saw a short figure walking along the wall.

His short black hair, high collar, and the striking red and white fan-shaped emblem on his back were particularly eye-catching.

Uchiha Sasuke is only seven years old this year.

When pedestrians saw the clan emblem, they all avoided it, their eyes filled with wariness and disdain. Sasuke was also disliked at this time.

Sasuke didn't react to this, or rather, he was used to it.

The atmosphere within the Uchiha clan has been extremely oppressive these past few days.

His father, Fugaku Uchiha, always had a stern face, and the clan members would gather together and whisper among themselves.

What saddened Sasuke the most was Itachi; his gentle older brother had also undergone a dramatic change without his knowledge.

Itachi started avoiding him, afraid that Sasuke would get close to him, and Sasuke felt like the whole world had abandoned him.

"Feed".

A voice interrupted Sasuke's thoughts, coming from the dilapidated shop next door.

Sasuke stopped in his tracks, his eyes filled with wariness.

Roy leaned against the door frame.

"The brat from the Uchiha clan."

"What's up?" Sasuke asked sharply.

Roy didn't care about this attitude.

"You look confused," Roy said, pointing to Sasuke's face. "It's written all over your face. About your brother, Uchiha Itachi."

Sasuke's eyes widened; this name was a taboo subject for him.

"Do you know Itachi?" Sasuke stared at the unfamiliar shop owner.

"I wouldn't say I know him personally, but I know why he's been acting strangely lately," Roy smiled.

Want to know?

Sasuke gripped the kunai in his pocket tightly.

This person is suspicious.

My father said that there have been many spies in the village targeting the Uchiha clan recently.

This shop has been open for half a month and no one has visited it. Something doesn't seem right.

"Are you the person the security forces are after?" Sasuke asked coldly. "If you're a liar, I'll have my father arrest you."

Roy shrugged.

"What's in it for me to lie to you? Do you even have any money on you?"

Sasuke was speechless; he really didn't have any money with him.

"What I'm selling here is information, and also an experience." Roy stepped aside to make room after the door opened. "Come in and take a look, it's free."

Sasuke hesitated.

Reason told him he should leave immediately and go home to report to his father.

But the temptation to learn the truth about Itachi was too great.

Sasuke gritted his teeth.

If it's a trap, he should be able to escape with his skills. He's a genius of the Uchiha clan.

Sasuke stepped into the store, which was dimly lit.

There were no shelves or any goods, just a chair and a table—it was as simple as it could be.

In the very center of the hall, there was a strange metal capsule.

The thing was streamlined, with a silver-white casing that gleamed coldly, and several indicator lights flashing on it.

"What is this?" Sasuke asked, pointing to the metal capsule.

"The Illusion Cockpit." Roy walked to the cockpit, patted the outer shell, and said, "It's a machine that lets you see the past and the future."

"The future?" Sasuke scoffed. "Even Naruto, that loser, wouldn't believe such a childish trick."

"Whether it's a scam or not, you'll find out by trying it."

Roy pulled open the cockpit hatch.

"Lie down inside. You'll see everything you want to know."

Sasuke took a step back.

Why should I believe you?

"Because you had no choice."

"Has your brother been coming home late a lot lately? Does he keep staring at you with a strange look in his eyes? Does your father often get angry at home? Are the clansmen holding secret gatherings?"

all hit.

These are clan secrets; how could an outsider know them?

"Who are you?" Sasuke's hand had already touched his ninja tool pouch.

"I'm a businessman." Roy pointed to the sign. "The owner of the Illusion Dojo. I believe in fairness in business. You give me payment, and I'll give you the truth."

"You just said it was free."

"It's really free; money is useless to me."

Roy held up one finger.

"I want ninjutsu."

Sasuke was stunned.

"Ninjutsu?"

"Yes. Your understanding of a certain ninjutsu, your memories of it, and the way your chakra flows. The system... oh no, this machine will extract this memory as a ticket."

Roy changed his tune very quickly.

"I want the Uchiha clan's signature ninjutsu, Fire Release: Great Fireball Technique."

Sasuke became highly vigilant.

Coveting the Uchiha clan's ninjutsu? That's a major taboo.

"This is a family secret technique and cannot be passed on to outsiders," Sasuke refused decisively.

"Come on," Roy waved his hand. "What kind of secret technique is the Fireball Jutsu in Konoha? Any Chunin with a bit of experience can do it. I just want your tips on how to use it, not the scroll."

Sasuke remained silent.

Indeed, the Great Fireball Technique is only a C-rank ninjutsu. Although it is the symbol of the Uchiha clan, it is widely known throughout the ninja world.

In exchange for the truth about Itachi, I'll use my knowledge of a C-rank ninjutsu.

This deal...

"Just extract memories? Will there be any side effects?" Sasuke asked.

"The feeling of taking a nap."

Sasuke stared at the metal capsule.

"it is good."

"If you dare to lie to me, I will burn your shop down."

The brat is making threats.

Roy gestured for him to proceed.

Sasuke walked to the cockpit, turned over, and lay down inside.

"Close your eyes," Roy's voice came.

Sasuke closed his eyes, and the hatch slowly closed.

Roy stood outside the cockpit, watching the data on the panel fluctuate.

[Customer detected: Uchiha Sasuke.]

[Payment Price: Fire Release: Great Fireball Technique (Proficiency: Beginner)]

The transaction is complete.

[Building a replica...]

[Target Node: The Night of the Uchiha Clan Massacre - Prelude.]

[Scene loading: Cliffs along the Namaka River.]

[Key character models imported: Danzo Shimura, Shisui Uchiha, Itachi Uchiha.]

Roy adjusted the dungeon parameters, thinking that if he was going to cause trouble, he had to go all out.

If you're going to do something, do it thoroughly and on a large scale.

Ordinary illusions can't fool the Uchiha; this is a 100% realistic, system-generated copy.

It can even simulate pain; you're probably going to suffer a bit.

"Kid, I don't expect you to thank me later, but don't blame me for now."

Roy looked at the completely closed cockpit.

"Rather than having my clan wiped out by my own brother in three days, I'd rather see what hell looks like now."

On the panel, the copy progress bar has started loading.

Roy pressed the red "Start" button.

The machine emitted a low hum.

The indicator light changed from green to red.

"Lie down in there." Roy's voice echoed like it came from the abyss. "Go and see what your brother is carrying on his shoulders."
