Mangekyō Sharingan?

Looking at the eyeball in the culture dish, glowing with a faint blue light, Uchiha Ensei felt incredibly excited.

But soon, as Sharingan ocular power was infused into it, the eyeball that had been giving off a blue glow suddenly emitted a trace of vivid red energy, then was instantly transformed...

It was as though it had been contaminated.

And in truth, that was exactly what had happened. Although the power within the eyeball had not weakened much, it was completely contrary to Uchiha Ensei's original goal.

"According to the Ōtsutsuki Clan's accounts, the Byakugan is the most important. Whether it is the Sharingan, Rinnegan, or Tenseigan, all of them are flawed evolutions of the Byakugan."

"It's just a shame I don't know how powerful the so-called Jōgan is."

"But the current result should already be the limit of what I can achieve. If I want to go further, I'll need some outside assistance."

Just as Uchiha Ensei was recording the experimental data and considering the next stage of his research, he suddenly sensed an unfamiliar chakra appearing in the laboratory.

"Who is it?!"

His eyes abruptly erupted with overwhelming ocular power, instantly intimidating the secretly infiltrating Shisui Uchiha.

After all, Shisui Uchiha also possessed a Mangekyō Sharingan. Thus, he broke free the instant he was intimidated by that immense ocular power, even analyzing quite a bit of information.

"This ocular power... it doesn't seem to be the ocular power of a Mangekyō Sharingan. It's far too diffuse, merely excessively vast... And these instruments, what exactly are they for?"

"You... are you really Uchiha Ensei?"

Shisui Uchiha had already revealed his Mangekyō Sharingan. If the answer given by the person before him failed to satisfy him...

Then the ocular technique he had kept hidden all this time, with a cooldown lasting several years, would have to be used.

Faced with the threat of Kotoamatsukami, Uchiha Ensei did not seem to care at all. He calmly sorted through his experimental data and neatly set it aside.

Glancing at the Ninja Cat trapped in a genjutsu by the door, Uchiha Ensei could not help sighing.

"Looks like the Ninja Cat Clan's combat strength is still somewhat lacking. It's time to begin researching Sage Art."

"But unfortunately, there's too little chakra in my body. Trying to master the power of nature now is still too much of a stretch..."

Listening to Uchiha Ensei speak as if no one else were present, Shisui Uchiha could not help furrowing his brow slightly.

Just as he could no longer hold back and was about to make a move, he suddenly heard Uchiha Ensei's words. One sentence alone made him stop all movement.

"Did you know? According to the original predetermined timeline, the Uchiha Clan has roughly three or four years left before it is exterminated."

Even Shisui Uchiha, who had always been calm, lost control somewhat upon hearing those words.

"How is that possible? What nonsense are you talking about? You're definitely not Ensei. Who exactly are you?"

After saying that, Shisui Uchiha attacked first, opening with a Mangekyō Sharingan ocular technique.

Both of Shisui Uchiha's eyes possessed Kotoamatsukami, but like Kamui, their left and right eye abilities functioned differently.

The Kotoamatsukami in his left eye was an ocular technique with a cooldown of several years, perhaps even over a decade.

The Kotoamatsukami in his right eye, meanwhile, had a short cooldown and could hypnotize enemies within a brief period.

Naturally, the Kotoamatsukami Shisui Uchiha used now was the one in his right eye. Yet this silent ocular technique, which theoretically could not be avoided at all, failed to work.

It was as if the figure standing before Shisui Uchiha was not a human at all, but a massive collection of ocular power. The technique vanished into it like a clay ox entering the sea, having no effect whatsoever.

Feeling a faint sting in his eyes, Uchiha Ensei understood what the other had done. Naturally, he had no interest in continuing the conversation, and he extended his left hand toward Shisui Uchiha.

In an instant, an invisible force surged forth, sending Shisui Uchiha and the surrounding wall flying far away together.

Fortunately, Shisui Uchiha had been standing by the entrance. Otherwise, if his laboratory had been damaged, that would have been troublesome.

He casually summoned several Ninja Cats and had them guard all the materials in the laboratory before turning and walking outside.

By the time he reached the outside of the house, Uchiha Ensei's home was already surrounded by Uchiha Clan ninja, each with scarlet Sharingan glaring fiercely and terrifying killing intent spilling from them.

Do not misunderstand. These Uchiha Clan ninja had not come to help Shisui Uchiha. They had merely been drawn over by the tremendous commotion.

"Shisui, what happened? Did an enemy attack?"

Fugaku Uchiha, who had arrived late, immediately spoke to Shisui Uchiha, who was struggling to climb up from the ground.

Uchiha Ensei's attack just now had come without the slightest warning and had been utterly impossible to evade.

Although Shisui Uchiha had not suffered any overly serious injuries, the enormous impact still left his entire body aching.

Faced with Fugaku Uchiha's question, Shisui Uchiha did not know how to answer.

"It's nothing. He merely infiltrated my home, so I threw him out."

Uchiha Ensei's small figure gradually emerged from the ruins.

When he fully entered everyone's sight, all eyes could not help being drawn to those strange eyes.

"Is that... a Mangekyō Sharingan?"

"Impossible! He's only ten years old. No matter how talented he is, that can't be possible!"

"A Mangekyō Sharingan isn't that color. Is it a bloodline mutation?"

"..."

For a moment, all kinds of noisy voices rose. Everyone was focused on Uchiha Ensei's eyes, while no one paid attention to the earlier incident anymore.

That was only natural. The Uchiha Clan's obsession with the Sharingan was fanatical, the kind of fanaticism that could make them disregard almost anything else.

Yet the more someone worshipped the Sharingan, the lower their chance of awakening it. Conversely, the more unwilling someone was to lose, the higher their chance of awakening it.

This truly suited the title of the cursed clan.

"Since there are no outside enemies, everyone other than Shisui and Ensei should disperse!"

Fugaku Uchiha was not in a particularly good mood. He did not feel as happy as he appeared to be over another pair of Mangekyō Sharingan appearing within the clan.

Especially when the one who had awakened them was a child.

A child meant unpredictability, perhaps even a threat. For the already precarious Uchiha Clan, that was not good news.

But he was naturally unwilling to abandon a genius who had awakened the Mangekyō Sharingan.

At this moment, Fugaku Uchiha was just like Shisui Uchiha beside him, always torn between two choices.
