Indra's chakra and memories from a thousand years ago

Kō stared intently at that faint Chakra, his heart churning with turmoil.

The eldest son of the Sage of Six Paths, the ancestor of the Uchiha bloodline, the creator of Ninjutsu, and arguably the progenitor of ninjas...

Even disregarding the "fusion of Otsutsuki 'Indra's Chakra and Asura Chakra," which is one of the important conditions for awakening the Rinnegan Indra, the Chakra that belongs to him alone is enough to make him impossible for anyone to ignore.

Kou silently observed this wisp of Chakra, his handsome face filled with caution.

He didn't rush to absorb it, but carefully and gradually guided the Chakra.

The faint blue light, drawn by him, gradually approached his right eye.

It then silently merged into his Mangekyō Sharingan.

The moment that Chakra entered the Mangekyo, Koko's body trembled slightly.

That Chakra, though tiny and only a trace, was incredibly pure.

The crimson eye power that he had just treasured was like Fire Fly compared to the bright moon in the face of this Chakra.

It's not a matter of quantity, but a world of difference in quality!

Those crimson pupils are branches and leaves, while this trace of Chakra is resin accumulated deep within the tree trunk over thousands of years.

Kou could feel that his Mangekyo had even become a little clearer under this power.

That's not just an increase in eye power; even the slightest increase is a fundamental sublimation!

His vision became clearer, and he could even feel that the subtle, imperceptible sluggishness was being smoothed out little by little by this force.

"Evolution, no, should I say 'atavism'...?"

Kō sensed the subtle changes in his Mangekyō Sharingan and murmured to himself.

As the Ninja World's first pair of Mangekyō Sharingan, Otsutsuki Indra naturally had no problem with blindness.

From the very beginning of his awakening Mangekyo, he was the Eternal Mangekyo.

No, to be precise, the concept of "Eternal Mangekyo" is itself a later development.

It is a product obtained by fusing the Mangekyo of a blood relative with the least rejection when one's own pupil power is insufficient, thus merging and evolving the pupil power of the two people.

As he thought of this, a bitter smile flashed in his eyes.

Although it was a hellish experience, he hadn't even had a chance to shake off his status as an only child before his parents died on a mission.

Having no siblings, I struggled for a long time with the question of how to unlock the Eternal Mangekyo.

But now it seems... a solution has been found, albeit barely.

"After all... where is there a better place to fuse eye power than with the Chakra of Uchiha Indra, the ancestor of the Otsutsuki?"

He murmured to himself with a sigh of relief.

Although this trace of Chakra was far from enough to evolve his Mangekyo, its effects were still extremely noticeable.

The plan to evolve one's Mangekyō Sharingan by absorbing Otsutsuki Indra's Chakra is undoubtedly feasible!

And the reincarnation of Otsutsuki Indra...

The image of the Uchiha cub he had flicked with his little QQ (a type of QQ chime) involuntarily flashed into his mind...

His lips curved slightly, he subconsciously swallowed, and murmured:

"Uchiha Sasuke..."

"Oh, it's me, your brother! I really miss you."

As soon as he finished speaking, Kou's expression suddenly froze.

"Hmm? Something feels off."

He muttered to himself, and a sinister figure involuntarily appeared in his mind.

A rare flicker of fear crossed Kou's eyes.

"No, no, I'm a normal person! A normal person!!"

"How could I possibly sit at the same table as that perverted Orochimaru?!"

Kou took a deep breath, banishing the dangerous thought from his mind.

He steadied himself and refocused his attention on the crimson eye power that was still pouring in.

Just as Kou was about to suppress his thoughts and continue absorbing the remaining eye power—

The things he saw had changed.

The red glow of the dome, the silent stone tablets, the walls covered with murals... everything vanished.

Instead, there are mountains.

Towering mountains reaching into the clouds.

Those mountain peaks are steep and majestic, like long swords piercing the earth and soaring into the sky.

White clouds swirled around the mountainside, and mist swirled in the valleys, shrouding the ancient buildings in a hazy glow.

Countless pavilions and buildings have been erected on those mountains.

They are built against the mountain, layer upon layer, stretching from the foot of the mountain all the way to the top.

Some resemble palaces, others towers; their shapes vary, yet they form a unified whole.

The stone steps meander like a snake, winding from the foot of the mountain all the way to the top, connecting every building.

At the summit, the most striking feature is a massive tower.

Its grandeur surpasses even that of the current Raikage Building.

The spire points straight to the sky, as if to pierce it. Sunlight pours down through gaps in the clouds, casting huge, moving patches of light across the tower.

Kou's gaze fell on the tall tower, on the most conspicuous spot on its surface.

There, there is a big word "shu" engraved on it.

Its strokes are vigorous and powerful, each stroke like a knife carving on stone, as if the person who carved the character was declaring something in this way.

Kou stood there, looking at the tower, the mountains, and the buildings that appeared and disappeared in the clouds and mist, a look of realization flashing across his eerie Mangekyō Sharingan.

"This is... the Land of Lightning?"

He murmured to himself, the light in his eyes deepening:

"No, should I say the location of the Land of Lightning a thousand years ago?"

"The Land of Lightning, and the Uchiha...?"

Kou seemed to have thought of something, and the expression on his handsome face changed from sudden realization to seriousness.

He stared at the tall tower with the word "shu" engraved on it, and the light in his eyes became brighter and brighter.

This is the "Land of Lightning" from a thousand years ago.

It is the location of the Ninjutsu School established by Otsutsuki Indra at the end of the Era of Ninshu, a thousand years ago!

Knock took a deep breath and whispered to himself:

"This is it..."

"The stronghold of Ninjutsu School a thousand years ago?"

(Sorry, I went back to school yesterday and only updated one chapter. I'll make up for it today!)
