Open, Kaleidoscope!

Uchiha Kei accepted the shock points provided by Itachi with a beaming smile.

"Ding! 1,000 shock points received. Can be exchanged for a random basic ninjutsu. Proceed with exchange?"

The system provided a timely prompt.

No kidding, of course I'm exchanging. Can't you see I'm about to show off?

Uchiha Kei chose to exchange without a moment's hesitation.

"Ding! Ninjutsu exchange successful. 1,000 shock points deducted."

"Obtained: Three-Tomoe Sharingan."

Uchiha Kei straightened his body abruptly, an irrepressible excitement appearing on his face.

The Three-Tomoe Sharingan!

The strongest kekkei genkai in the early stages of the ninja world!

"I don't know what you're talking about, Kei."

Itachi did not notice the excitement on Uchiha Kei's face; he feigned composure, though his gaze was actually somewhat unfocused.

He could not understand why this ordinary little guy, who was usually so unremarkable, had undergone so many changes in a single day.

"Ah, is that so?" Uchiha Kei forced himself to adjust his emotions. "Then I believe Brother Shisui will understand my words. After all, his eyes possess an unsolvable ability."

"You!"

"Ding! Received shock from Uchiha Itachi. Shock points +99."

"Ding..."

"Ding..."

In an instant, Uchiha Kei had harvested nearly 500 shock points!

Uchiha Kei's face immediately broke into a wide grin.

Today was truly a good day; first Naruto, then Itachi.

If things went like this every day, he would dare to challenge Obito to a duel in a year at most!

And he would beat him to a pulp!

"What else do you know!"

Itachi no longer hid the shock on his face, looking at him in disbelief.

"I certainly know more than you do."

A calm smile played on Uchiha Kei's face.

"The Uchiha clan is a cursed clan. Even for Brother Shisui, while his eyes are indeed unsolvable, it is still to no avail!"

Itachi did not want to dwell on this matter any further; when he heard Uchiha Kei mention Shisui, the last line of defense in his heart had already crumbled.

"Cursed?"

Uchiha Kei scoffed at this notion.

The way the Uchiha clan awakened and evolved their eyes was indeed cruel, but that was only because they didn't know how to use them properly.

At the very least, as a viewer, Uchiha Kei knew dozens of ways to awaken them without harm from his past life.

"Look at me."

Uchiha Kei's voice suddenly became hollow. Itachi's mind was already somewhat scattered, and upon hearing this, he obediently looked up.

A pair of scarlet eyes suddenly reflected in his vision, the three tomoe rotating slowly like a bottomless vortex.

"BOOM!"

Itachi's body jolted violently. A deafening roar erupted in his ears, and amidst the roar, heart-wrenching screams were intermingled.

"Why are you killing us!"

"We are the Uchiha clan! We are members of Konoha!"

"Why! Why!"

Itachi looked around in a daze, discovering that this was actually the residential district of their Uchiha clan.

This... what was going on?

Wasn't he just chatting with Kei a moment ago?

Just then, a familiar cry interrupted his thoughts.

"Wuwuwu, no, don't!"

Sasuke!

Itachi immediately became flustered and rushed toward the sound.

Walking into a familiar courtyard, Itachi knew this was his home.

His home was no longer as peaceful as it usually was; blood flowed from the house, staining the entire ground red.

Itachi walked forward with trembling steps and gently pushed open the door.

"Fa... Father... Mo... Mother..."

Itachi stared blankly at his silent parents, scarlet blood pooling beneath them.

"How could this happen... How could this happen..."

Itachi watched in disbelief, a needle-like pain piercing his brain.

"Ah!"

Just then, another scream erupted from the inner room.

"Sasuke!"

Itachi let out a roar, drew his ninja blade from his back, and charged frantically into the inner room.

"Swish!"

As Itachi pushed open the door, he caught sight of a cold glint, and the blade in his hand clattered to the floor.

Inside the room, a thin figure gripped a sword, having just sliced off a child's head.

Blood gushed wildly from the neck, and on the floor, a head with a face frozen in terror stared directly at him.

"Sa... Sasuke!!"

Itachi stepped forward shakily, not daring to believe it as he reached out to touch the head.

It was soft and still held a trace of warmth.

"Impossible! Impossible! It's fake, it's all fake!"

Two lines of blood-red tears streamed from his eyes, and his three-tomoe Sharingan activated automatically, beginning to spin along a certain trajectory.

The tails of the three tomoe began to extend, and gradually, more and more mysterious patterns began to spread.

"Why would it be fake?"

The thin figure crouched down, his tone filled with cold indifference.

"This is your mission, have you forgotten?"

"My... my mission?"

Itachi looked up in confusion, only to see a familiar face.

It was himself!

"Yes, your mission." The other Itachi's face was icy, devoid of any emotion.

"Your mission is to eliminate the rebellious Uchiha clan..."

"Leave no one alive!"

Itachi's mouth hung wide open, his throat emitting a rattling sound as the scarlet patterns of his Sharingan grew increasingly dense.

"No! This is not my mission!"

Itachi rasped, "I want to protect the Uchiha clan, protect Sasuke! I could never do such a thing! Impossible!"

"But you already have."

The other Itachi coldly grabbed the head from the floor. "You killed them all!"

"It was you!"

"Uchiha Itachi!"

The transformation of Itachi's Sharingan accelerated instantly, shifting into a complex, polygonal pattern in the blink of an eye.

"No!"

Itachi stood up abruptly, blood flowing faster from his eyes as red skeletal structures enveloped his entire body.

"Wake up!"

Uchiha Kei was suddenly knocked over by the initial form of the Susanoo; his vision went black, and a mouthful of blood sprayed out.

Itachi broke free from the illusion in an instant, looking at the Susanoo with a dazed expression.

"This is... this is..."

"Hoo." Uchiha Kei took a long breath and wiped the corner of his mouth. "The initial form of the Susanoo."

"Susanoo!"

Itachi stood up abruptly, and the massive skeleton instantly tore through Uchiha Kei's thatched cottage.

"I told you, there is more than one way to activate the Uchiha's Sharingan."

Uchiha Kei looked calmly at the completely destroyed cottage, feeling a sense of sorrow in his heart.

He had finally had a place that could barely keep out the wind and rain, and now, he would have to sleep on the streets...

"My... my eyes..."

Itachi touched his eyes in disbelief.

Susanoo was an ability that could only be wielded by those with the Mangekyō Sharingan.

Then, did that mean he was currently...

Already in possession of the Mangekyō Sharingan?

"Ding! Received shock from Uchiha Itachi, Shock Value +999!"

The unprecedented amount of shock left even Uchiha Kei, standing off to the side, feeling completely bewildered.

One instance of shock, one random ninjutsu!

This trade was far too profitable!

In an instant, Uchiha Kei suddenly felt that sleeping on the streets might not be so hard to accept after all.

After all, once he had the strength, he could afford a house of any size!

Not just a house, he could eat whatever he wanted!

Once fed and satisfied, he could even find a beautiful woman to be his wife!

In the span of a few breaths, Uchiha Kei had already begun to imagine his future life of happiness.

PS: Many people question why I define the Mangekyō as a primary level, but I don't see it that way. The Mangekyō is indeed very powerful in Shippuden, but is it as powerful as the Rinnegan? The Ōtsutsuki basically all have the Rinnegan, so does that make the Rinnegan the most powerful? Not necessarily! I define the Mangekyō as primary, the Rinnegan as intermediate, and things beyond the Rinnegan as advanced—I might even write about ultimate things if the conditions allow! After all, I don't intend for this novel to end in the Ninja World; it's going to Takamagahara. If I wrote the Mangekyō as an advanced level, would I just be sending him to Takamagahara to die?
