Mangekyo Sharingan?

As he gazed at the eyeball floating in the culture dish, emanating a faint blue glow, Uchiha Yansheng felt incredibly excited.

But soon, as Sharingan ocular power was infused into it, the eyeball that had originally glowed with a blue halo suddenly released a trace of vivid red energy before being 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 by much, the result was completely contrary to Uchiha Yansheng's original goal.

"According to the Ōtsutsuki Clan's records, the Byakugan is the most important. The Sharingan, Rinnegan, and even the Tenseigan are all flawed evolutions of the Byakugan."

"Unfortunately, I don't know how powerful the so-called Pure Eye 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 help."

Just as Uchiha Yansheng was recording the experimental data and considering his next research plan, he suddenly sensed an unfamiliar chakra emerging within the laboratory.

"Who is it?!"

A powerful surge of ocular power erupted from his eyes, instantly intimidating the secretly infiltrating Shisui Uchiha.

Shisui Uchiha had Mangekyo Sharingan as well, so he broke free almost the instant he was intimidated by that immense ocular power. He had even analyzed quite a bit of information from it.

"This ocular power... it doesn't feel like Mangekyo Sharingan ocular power. It's far too scattered, merely overwhelmingly vast... And these instruments, what exactly are they for?"

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

Shisui Uchiha had already revealed his Mangekyo Sharingan. If the answer from 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 Yansheng appeared entirely unconcerned. He calmly sorted out his experimental records and neatly set them aside.

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

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

"But unfortunately, there's too little chakra in my body. Trying to harness natural energy now is still too much of a stretch..."

Listening to Uchiha Yansheng speak as though no one else were present, Shisui Uchiha's brows furrowed slightly.

Just as he could no longer endure it and was about to make a move, he suddenly heard Uchiha Yansheng's words. A single sentence stopped all his movements.

"Did you know? According to the original predetermined timeline, the Uchiha Clan will be wiped out in roughly three or four years."

Even Shisui Uchiha, who was usually calm, lost control somewhat upon hearing those words.

"How is that possible? What nonsense are you spouting? You are definitely not Yansheng. Who exactly are you?"

With that, Shisui Uchiha launched the first attack, opening with a Mangekyo Sharingan ocular technique.

Both of Shisui Uchiha's eyes possessed Kotoamatsukami, but like Kamui, the left and right eyes had entirely different applications.

The Kotoamatsukami in his left eye was an ocular technique with a cooldown lasting several years, or even more than a decade.

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

What Shisui Uchiha used now was naturally the Kotoamatsukami of his right eye. Yet this silent ocular technique, which should have been impossible to avoid, had lost its effect.

It was as though the figure standing before Shisui Uchiha was not a human at all, but a massive aggregate of ocular power. The technique vanished into it like a clay ox entering the sea, accomplishing nothing whatsoever.

Feeling a faint stabbing pain in his eyes, Uchiha Yansheng understood what the other party had done. Naturally, he no longer had any interest in continuing the conversation, and he extended his left hand toward Shisui Uchiha.

In an instant, an invisible force surged forth, blasting Shisui Uchiha and the surrounding wall far into the distance.

Fortunately, Shisui Uchiha had been standing by the doorway. 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 inside the laboratory before turning and walking out.

By the time he reached the outside of the house, Uchiha Clan shinobi had already gathered all around his home. Each of them glared with scarlet Sharingan, radiating terrifying killing intent.

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

"Shisui, what happened? Has an enemy attacked?"

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

Uchiha Yansheng's previous strike had shown no warning whatsoever and had been completely impossible to evade.

Shisui Uchiha had not suffered any especially serious injuries, but the tremendous impact still left his entire body wracked with pain.

Faced with Fugaku Uchiha's question, Shisui Uchiha did not know what to say.

"Nothing. He merely infiltrated my home, so I threw him out."

Uchiha Yansheng's small figure slowly emerged from the rubble.

When he fully entered everyone's field of vision, every gaze was inevitably drawn to his strange eyes.

"Is that... Mangekyo Sharingan?"

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

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

"..."

For a time, all kinds of noisy voices arose. Everyone was focused on Uchiha Yansheng's eyes, while no one paid attention to the incident that had brought them here.

That was only natural. The Uchiha Clan's obsession with the Sharingan was fervent, the sort of fervor that could make them ignore nearly everything else.

Yet the more someone worshiped the Sharingan, the lower their chances of awakening it became. Conversely, the more unwilling someone was to lose something, the greater their chance of awakening it.

This truly fit the title of cursed clan remarkably well.

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

Fugaku Uchiha was not in a particularly good mood. Although another pair of Mangekyo Sharingan had appeared within the clan, he was not as delighted as he appeared to be.

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

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

Yet he was naturally unwilling to give up a genius who had awakened the Mangekyo Sharingan.

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