It Was Discovered by Itachi

Narak quietly leaped onto the roof of Sasuke's house without making the slightest sound, then continued observing the area below with Byakugan.

At that moment, inside the living room of Sasuke's house, Sasuke looked at his parents lying in a pool of blood, barely breathing. Facing Itachi, who was dressed in black night clothes, he asked agitatedly, "Brother, Father and Mother... why...? Who did this?"

However, faced with Sasuke's question, Uchiha Itachi did not speak. Instead, he flicked his hand and threw a Shuriken at Sasuke. The sharp Shuriken sliced through Sasuke's arm and embedded itself in the wall behind him.

"Brother, what are you doing?" Sasuke covered his bleeding arm and looked at his brother in disbelief.

Itachi still did not answer Sasuke's question.

Unwilling to give up, Sasuke asked again, "What are you doing, Brother??"

This time, Itachi finally spoke. He said coldly to Sasuke, "You foolish little brother."

Then, Itachi cast the Mangekyō Sharingan on Sasuke.

As the ocular technique took effect, Sasuke was pulled into the illusion Itachi had cast. Within the illusion, Sasuke saw how cold-bloodedly his brother slaughtered the clan members. One familiar clan member after another fell beneath his brother's blade, until finally, even their parents were brutally killed by Itachi.

The bloody scene played out in Sasuke's mind again and again. Poor Sasuke was only an eight-year-old child—how could he accept such a reality? His fragile psychological defenses collapsed in an instant.

After the illusion ended, Sasuke, his mind shattered, collapsed to the ground and stared blankly at his brother.

"Why... why... Brother..." Sasuke kept asking over and over.

Faced with Sasuke's questions, Itachi merely said, "To test my abilities."

Sasuke looked at Itachi in disbelief. Struggling, he rose from the ground.

"Test... your abilities? Just for that, you killed everyone..."

"Because it was important," Itachi replied.

"Important? Are you kidding me?" Enraged, Sasuke found strength from somewhere and swung his fist at Itachi.

Bang!

With a single move, Itachi struck Sasuke in the stomach and knocked him to the ground.

Sasuke lay on the ground and looked up at Itachi, tears gradually welling in his eyes.

Itachi took a step toward Sasuke. Terrified, Sasuke scrambled up from the ground and ran outside, shouting continuously, "How scary... Don't kill me... Don't kill me..."

The broken Sasuke sprinted down the street, but after only a few steps, he suddenly came to a halt. Itachi stood directly in front of him.

Looking at Itachi before him, Sasuke still could not believe it. Forcing himself to remain calm, he said, "This is all a lie. This wasn't done by you, Brother, because you..."

Before he could finish, Itachi interrupted him: "The reason I kept playing the role of the brother you expected was to test your abilities. You will become the subject used to measure my abilities in the future. You possess that potential."

"You will grow tired of me. You will come to hate me. You will constantly hope to surpass me. That is why I let you live."

"You are like me. You are someone who may learn the Mangekyō Sharingan."

"But there is one condition: you must personally kill your best friend."

Next, Itachi revealed to Sasuke the secrets related to the Uchiha Clan's ocular techniques, as well as his expectations for Sasuke.

Finally, he said to Sasuke, "But the you of now is not worth killing, you foolish little brother."

"If you want to kill me, then hate me. Despise me. Then struggle to survive in an ugly fashion."

"Run. Seize this slim chance at survival. Then, one day, when you possess eyes like mine, come before me."

After saying this, Itachi used the power of the Sharingan on Sasuke. Already utterly terrified, Sasuke was instantly knocked unconscious by the force.

Watching the melodramatic farce below finally come to an end, Narak could not help curling his lip.

Narak still remembered the matter of Itachi wiping out the Uchiha Clan.

It had started with the Uchiha Clan growing increasingly arrogant. They thought they were strong enough to become the village's leaders, so they planned to rebel and overthrow the Hokage's rule.

Unfortunately, everything had been seen by Konoha's higher-ups. The Uchiha believed their plan was flawless, but in reality, the Hokage and Danzo had already woven a massive net, waiting to catch them all in one sweep.

Faced with such a situation, Itachi could only choose to personally exterminate the entire clan. In return, he would protect his most beloved little brother and allow Sasuke to continue living peacefully in Konoha.

As an elder brother, Itachi had truly exhausted himself for Sasuke.

"System, sign in." Without bothering about Sasuke, who had fainted on the ground below, Narak spoke to the system.

"Ding, sign-in successful."

"Congratulations, host. This sign-in rewards you with: Advanced Spiritual Pressure, Advanced Flash Step, Kido sequences 30–60, Hado sequences 30–60, and Eight Trigrams Sixty-Four Palms (Proficient)."

As the system's voice faded, Narak felt the power within his body surge instantly. The immense strength filled him with an overwhelming sense of fullness.

At that moment, Narak felt that he could shatter the space before him with a single punch. Of course, he knew this was merely an illusion caused by suddenly gaining immense power that he could not yet control.

"Yoshi, I've finally broken through to Advanced Spiritual Pressure. Flash Step has reached the advanced level as well. At the speed of Advanced Flash Step, no one in the Naruto world can catch me over short distances. This adventure was worth it."

Narak clenched his fist and began slowly familiarizing himself with the power within his body.

"Narak-kun, staying up so late and running onto someone else's roof to spy on them... As the eldest son of the Hyuga Clan, that isn't a very polite thing to do."

Suddenly, a calm voice came from behind Narak.

Narak's heart jolted. He used Flash Step beneath his feet and left his original position.

After advancing to Advanced Flash Step, Narak's speed was more than twice as fast as before.

That terrifying speed instead secretly shocked Itachi behind him.

Narak was very fast. Many people in Konoha knew that, but before this, most had only heard about it. After witnessing it for himself today, Itachi was still extremely shocked.

"Narak-kun, I've always heard that you were fast. Only after seeing it for myself today do I know that the rumors weren't exaggerated. At your speed, you probably wouldn't be much slower than Body Flicker Shisui in his prime. The only person who could surely outpace you was probably the Fourth Hokage with the Flying Thunder God Technique. But both of them have passed away. Now, I, Uchiha Itachi, am willing to call you the fastest man alive."

After flashing to another rooftop, Narak watched Itachi from the corner of his eye, avoiding direct eye contact to prevent him from using an illusion.

"Hey, hey, be clear. I'm fast in terms of movement speed, not in other ways. Calling a man fast is an insult, you know," Narak said unhappily.

"..." Itachi's face darkened.

I'm talking to you seriously. Are you trying to make this dirty? We're both minors—can't we have a pleasant conversation?
