Ninja Sect and Sage Sect

Due to the impurity of their bloodlines, the Mangekyo Sharingan of the Warring States period already carried the risk of blindness.

Furthermore, it had regressed to the level of the standard Sharingan; nowadays, even a three-tomoe could be considered a Mangekyo Sharingan, but back in the Warring States period, it was merely classified as a Sharingan.

"By nourishing the Mangekyo Sharingan and the Byakugan with chakra, once the concentration of ocular power within them reaches a certain level, the Mangekyo Sharingan will evolve."

"And if the Byakugan and the Mangekyo Sharingan are fused, there is a one-in-a-million chance of evolving into the Rinnegan."

"If the Otsutsuki gene lacks the Sharingan gene, it directly leads to the loss of the ability for the trophoblast brain cell lineage to awaken the Sharingan; it then becomes the Senju gene or the Uchiha gene, which is the origin of the Sage Body and the Sage Eyes."

"After absorbing the ocular power of these Byakugan and Mangekyo, the time it takes for my Mangekyo Sharingan to evolve into the Rinnegan will be greatly shortened. If the progress continues at this rate, then in less than three years, my Byakugan and Mangekyo Sharingan will be able to evolve into the Rinnegan and the Tenseigan."

Otsutsuki Yuhao thought to himself.

Through more than twenty years of research, Otsutsuki Tatsuten's human body technology was—by his own admission—second only to Orochimaru's, and because he possessed the superior vision of the Byakugan, in some areas, Otsutsuki Yuhao was even more exceptional than Orochimaru.

In this world, which was close to a primitive civilization, he didn't even need a magnifying glass.

It was fortunate that he had the Byakugan; otherwise, it would have been much more difficult for Otsutsuki Yuhao to study his own cells.

In an open clearing.

Two figures were colliding rapidly.

A sharp glint cut through the air once more as two short swords clashed, sending intense sparks flying.

Zi Tianming quickly adjusted the angle of his short sword, grabbed Qinshou's arm with his left hand, and thrust his sword toward her with his right.

However.

Qinshou's reaction speed was swift; she instantly drew the blade at her waist and blocked the strike directly.

The two weapons struck each other, emitting a crisp metallic clang.

The sound of weapons clashing echoed continuously in the surroundings.

Immediately after, Zi Tianming threw a punch, attempting to force Qinshou back.

However, Qinshou dodged the strike nimbly in mid-air and landed a kick squarely on Zi Tianming's face.

Zi Tianming was knocked to the ground, but he quickly steadied his body and stood up firmly.

[Fire Style: Great Fireball Technique (B)]

Zi Tianming performed hand seals rapidly, exhaling a fireball four or five meters in diameter toward Qinshou.

[Water Style: Water Formation Pillar (B)]

After gathering chakra in her throat, Qinshou instantly spat out a sphere of water that looked like a falling meteorite, extinguishing Zi Tianming's Great Fireball.

"This move again?"

"Let's see how you extinguish my fire this time!"

Zi Tianming shouted, his hands moving in a blur of seals.

[Fire Style: Dragon Flame Song Technique (A)]

Zi Tianming exhaled a twenty-meter-long fire dragon from his mouth, attacking Qinshou.

"An A-rank ninjutsu? It seems you really want to play for keeps!"

[Water Style: Water Dragon Bullet]

Qinshou spat a stream of water from her mouth to form a water dragon, which was even larger than Zi Tianming's fire dragon.

Boom!

The moment the water dragon and fire dragon collided, a massive explosion erupted instantly.

Everything within a hundred-meter radius was devastated by the force of these two chakra powers.

The air was filled with water mist and the smell of scorching, as the two elemental ninjutsu dissipated into nothingness after the collision, leaving only a scene of wreckage behind.

Zi Tianming panted heavily, a look of determination flashing in his eyes. He had not expected Qinshou's strength to be so formidable that she could easily handle even his A-rank ninjutsu. Yet, he was not discouraged; instead, it ignited his fighting spirit.

"It seems I have to bring out my real skills!" Zi Tianming muttered to himself, his hands quickly forming seals once more.

[Fire Style: Phoenix Sage Fire Technique (S)]

This time, Zi Tianming did not exhale flames directly; instead, he pushed his hands forward. Dozens of fireballs flew out from between his palms simultaneously, dancing in the air like a flock of fire phoenixes before rushing toward Qinshou at high speed.

Faced with this sudden attack, Qinshou was also taken aback. She had not expected Zi Tianming to possess such a powerful ninjutsu. However, she did not panic and quickly performed her own seals.

[Water Style: Great Waterfall Technique (S)]

Qinshou waved her hands forward, and a massive column of water surged from her palms, instantly transforming into a waterfall-like torrent to meet the incoming fire phoenixes.

Water and fire met in the air once more, emitting a thunderous roar and creating a powerful shockwave. Everything around them swayed unsteadily, as if it could be swept away at any moment.

Zi Tianming and Qinshou stared fixedly at each other, their eyes burning with resolve. They knew that this battle had only just begun, and the true outcome remained to be seen.

"[Shinra Tensei]"

Just then, the voice of Otsutsuki Tatsuten rang out.

An invisible force instantly cleared away all the chakra.

"Are you two trying to destroy this entire forest?"

Otsutsuki Yuhao spoke to Zi Tianming and Qinshou with a tone of annoyance.

Although Otsutsuki Tatsuten had not yet awakened the Rinnegan, he could still utilize some of its basic abilities.

This was because Otsutsuki Yuhao's Byakugan possessed this very capability.

"If you want to play, go play by the seaside!"

Otsutsuki Tatsuten said to the two of them.

"Go to the seaside? Then it's even more impossible for me to be a match for Senior Sister. She practices Water Release Ninjutsu, and as a Fire Release Ninja, how could I possibly be her opponent?"

Zi Tianming said with a bitter smile.

"Teacher, you can't blame me for this!"

"I already said we shouldn't use ninjutsu, but in the end, Zi Tianming used it anyway."

Qinshou blinked her large eyes, her petite nose wrinkling slightly as a sweet smile bloomed at the corners of her mouth.

She clung to Otsutsuki Yuhao's arm, acting spoiled with a delicate, cooing voice that couldn't help but soften Otsutsuki Yuhao's heart.

This kind of life is certainly not bad!

But...?

Otsutsuki Yuhao thought to himself, yet the moment he considered those extraterrestrial Otsutsuki, a sense of unease began to stir in his heart.

Although the Otsutsuki were not supposed to arrive in the ninja world for another thousand years, Otsutsuki Yuhao did not know if the appearance of someone like him in this world would cause them to arrive early.

Furthermore, he had clearly transmigrated into the Naruto world, yet he could not see protagonists like Naruto or Sasuke, and he was destined to grow old and die in this world.

This left Otsutsuki Yuhao feeling truly unreconciled.

If that were really the case, it would be too absurd.

"Senior Sister and Teacher, their relationship is clearly more than just that of a master and disciple. They're practically about to kiss!"

Zi Tianming watched Otsutsuki Yuhao and Qinshou with a sense of helplessness.

Although Qinshou and Otsutsuki Yuhao were master and disciple, everyone in the Sage Sect could see that while they were called master and disciple, they were actually more like lovers.

However, because Qinshou had been with Otsutsuki Yuhao the longest, naturally, no one said anything, and in this era, it was not particularly strange for a teacher and student to end up together.

"Alright, you're about to become a grandmaster-level figure; stop acting like a child."

Otsutsuki Yuhao gently pushed Qinshou away.

"So what if I'm a grandmaster? Even a Great Grandmaster would be a child in front of Teacher!"

Qinshou revealed a sweet, gentle smile, gazing at Otsutsuki Yuhao with deep affection.

Such a look always made Otsutsuki Yuhao feel strange.

Otsutsuki Yuhao could guess that Qinshou liked him, but he hadn't paid much attention to it in the past, focusing most of his energy on human body research instead.

Regarding Qinshou's feelings for him, Otsutsuki Yuhao simply regarded her as a younger sister and a disciple.

Three years later.

Asura and Indra returned to the Ninja Sect.

Over these three years, Asura and Indra had pacified the conflicts between villages across the world.

The techniques of cultivation and animal husbandry were spread throughout the world by these two brothers.

Because both of them hailed from the Ninja Sect, this time, the reputation of the Ninja Sect finally spread across the entire world.

Renowned throughout the world, perhaps they would even be remembered in history books for centuries to come.

In the ninja world, the Ninja Sect represented the ninjas, while the Sage Sect represented the commoners.

The Ninja Sect was the strongest, while the Sage Sect was the kindest.

This was the consensus among all the common folk.

However, at this moment, the status of the Ninja Sect in the eyes of people worldwide was no longer inferior to that of the Sage Sect.

Perhaps Otsutsuki Yuhao had never imagined that the Sage Sect he had created on a whim would attain such a reputation in the world.
