Mangekyo Sharingan

Outside the Hidden Leaf Village.

"So, Lord Madara, you've agreed to take me with you?" Shin'yu asked softly.

"Mm." Madara nodded proudly.

Whether it was Shin'yu's experiences or those Mangekyo Sharingan eyes, both had resonated with him. Fellow sufferers as they were, whether as a follower, an assistant, or even a successor, he had already decided to take Shin'yu with him as they wandered the world.

"Thank you, Lord Madara." Shin'yu finally revealed a knowing smile.

"The abilities of these eyes are my greatest secret..."

He raised a hand, his fingertips gently brushing over his eye sockets. His pupils were crystal clear, carrying a jade-like texture.

"But since it's Lord Madara, there's no harm in telling you!"

Under Madara's curious gaze, Shin'yu began to explain.

The ocular technique in his left eye was called "Mahoraga." Its ability was to adapt to all phenomena and unleash the strongest counterattack against whatever it adapted to—in other words, the ultimate counterpunch born after adapting to all things in the world.

More specifically, it could endlessly analyze everything he touched or saw. This process was called adaptation. Once adaptation was complete, it could nullify this type of influence, granting permanent damage immunity and allowing him to launch a tangible counterattack against the source.

The power of adaptation conformed to causality and would not be erased by time and space. Moreover, suffering attacks again during the adaptation period would accelerate the process.

So-called "endless analysis" meant that even after an attack had already been adapted to, the analysis would not stop. It would only become more and more optimized!

The only thing it could not adapt to was the damage inflicted on his eyes when Eye Power was consumed.

The ocular technique in his right eye was called "Ame no Tokotachi." Its ability was time and space reversal.

It could freely reverse his own temporal and spatial state, unconditionally restoring his current state to that of a certain moment in the past. Its maximum range was five minutes, its temporal scale approached infinity, and after activation, it had only a one-second cooldown.

Whether it was a temporal state or a spatial state, either could be selected freely.

However, a point in time where a reversal had already been performed could not be chosen again as the target point for reversal.

The more Madara listened, the more intrigued he became. His eyes gleamed with excitement. "Infinite adaptation, time and space reversal—these are true divine techniques. And when the two are used together, the effect is even more extraordinary."

It had to be said that this Uchiha Clan Head had a sharp eye.

Shin'yu blinked. In truth, he had concealed a tiny detail about the power of his right eye.

The targets Ame no Tokotachi could reverse were not limited to himself!

Everything in the world, so long as it lay within his sight, could undergo time and space reversal!

The target of reversal could only be defined as a macroscopic individual at most. However, that would consume a massive amount of Chakra. The greater the target's influence on the macroscopic world and the farther back the selected point in time, the more severe the Eye Power consumption.

He really could not be blamed for holding back from Lord Madara. If the full abilities of his right eye became known, it would mean he was not merely the strongest shield, but also the strongest support! Who knew whether Madara would use him as a tool?

Living in this ninja world, one had to keep something in reserve at all times.

"Alright, let's go."

Madara turned around, the earlier melancholy completely washed away by the joy of taking Shin'yu in.

But Shin'yu did not move.

"What?" Madara tilted his head slightly and asked in confusion, "Did you leave something behind?"

"Mm... you could say that." Shin'yu smiled faintly. "Lord Madara, there is actually one more clansman who has Opened the Mangekyo Sharingan."

"What?" Madara asked in alarm and uncertainty. "Could it be your Younger Brother?"

Shin'yu shook his head. "He doesn't have that talent. Even now, he hasn't even Opened his eyes, but that isn't important..."

"...Lord Madara, do you remember the sealed... secret weapon of the Uchiha Clan from the middle of the Warring States Period?"

"The secret weapon of the Uchiha Clan?" Madara pondered for a moment before suddenly realizing.

The dust of years drifted down, and an event buried for many years slowly surfaced in his heart.

Many years ago, when Madara had not yet become Clan Head, a little girl named Uchiha Hikari had emerged from the Uchiha Clan.

Like Shin'yu, she had awakened the Mangekyo Sharingan at a very young age. Her ocular technique, Yachihoko, could be called a divine technique.

Yachihoko could mark enemies and absorb their Chakra to strengthen herself. As long as a mark had been placed, she could use the connection to control a person's mind and Chakra. Chakra could also be transmitted to herself or others regardless of distance.

Such a skill naturally drew the attention of her own clan. The clan's rulers treated her as a secret weapon and imprisoned her in a pitch-black dungeon, only releasing her when battle was required.

Yet that was not enough. In pursuit of the ultimate power, those madmen forcibly implanted the two ocular techniques, Amaterasu and Tsukuyomi, Inside the body of the girl. They completely turned her into an Uchiha weapon, stripping her of her name, freedom, and the right to be a "person."

Thus, the Uchiha's strongest weapon—Nanashi—was born.

Nanashi's appearance immediately reversed the Uchiha's decline on the battlefield. After suffering setbacks, the Senju Clan joined forces with other ninja clans and began targeted operations against her.

In the end, at an enormous cost, they finally sealed Nanashi away.

"Could it be that you want to free her?" Madara asked.

"Mm. She's also someone who was abandoned. If we can bring her into our group, then under your leadership, Clan Head, wouldn't we become a new Uchiha?" Shin'yu guided him step by step.

"A new... Uchiha?" Madara froze. A warm current surged through his heart, and some dark corner within him brightened.

"But..." He frowned slightly. "That happened a long time ago, and even I don't know where she was sealed."

"Just because you don't know doesn't mean the Hidden Leaf Village doesn't." Shin'yu revealed an ill-intentioned smile. "I'd wager that a secret scroll about that weapon is stored in a hidden chamber within the Hokage Building."

Although he did not know the exact sealing location either, according to his memories, that information was recorded in a secret scroll called Warring States Sealing History, and secret scrolls were generally kept in hidden chambers within the Hidden Leaf Village.

"I see..." Madara fell into thought, finding himself in a difficult position.

He had just proposed a "breakup" to Hashirama and had only just left the village. If he went slinking back now... it was not his style!

Shin'yu saw Madara's hesitation and immediately patted his chest. "Lord Madara, I can sneak back in and steal the secret scroll under cover of night."

"That would be dangerous for you, wouldn't it? Aren't you afraid of being discovered by Senju ninja?" Madara gazed toward the Hidden Leaf Village and shook his head.

Shin'yu smiled confidently. "Lord Madara, Body Flicker and stealth are what I'm best at. They won't discover me. Even when I chased after you out of the village, I avoided everyone's sight."

"No wonder you didn't come out with me right away. So you had such a plan..." Madara mused.

He was a man of swift and decisive action, and he immediately agreed to Shin'yu's Plan.

The two agreed to act that night. Whether Shin'yu succeeded or failed, he had to leave the village before the moonlight was at its brightest, while Madara would remain hidden outside the village to meet him.

Immediately afterward, Shin'yu's right eye bloomed with crimson light. As the Mangekyo pattern Slowly Rotating, fine blood vessels suddenly spread across the white of his eye.

The setting sun was red as blood, fiery clouds drifted overhead, fallen leaves hung suspended in mid-air, and the Wind Sound stopped beside his ears. Time seemed to have frozen at that moment.

From Shin'yu's perspective, his body had left behind a strange, twisted trail through space, like a long noodle stretching from here all the way to the Hidden Leaf Village.

His vision seemed to have shifted into four-dimensional space. That progress-bar-like existence was precisely the trail he had left while moving through space over the past five minutes, every moment clearly visible.

Now, he could freely drag this progress bar. After choosing a point in time and pressing play, he would immediately appear at the selected location.

This was his ocular technique, Ame no Tokotachi.

Shin'yu dragged the progress bar to its limit. Five minutes earlier, he had been hiding in a concealed patch of grass within the village.

In the next instant, he vanished before Madara's eyes. The clean, abrupt disappearance was like erasing a pencil mark with an eraser—gone in a flash.
