Space-Time Mission

If the Sharingan was a major bug in the early stages, then in the late stages where power levels collapsed and cheaters ran rampant, the Rinnegan would absolutely hold a place of its own.

What kind of experience would it be to possess the Rinnegan in the early stages?

One could refer to Nagato destroying Konoha single-handedly!

If it weren't for Naruto returning in time, Konoha might have truly been destroyed!

"Exchange!"

Uchiha Kei did not hesitate in the slightest.

However, the system prompt that followed left him stunned.

"Ding, the Rinnegan belongs to the Six Paths level of ninjutsu. It requires the completion of a Space-Time Mission to exchange. Do you wish to execute?"

Uchiha Kei was taken aback. A Space-Time Mission? What kind of nonsense was this?

Although he didn't understand what a Space-Time Mission was, compared to the immense combat power brought by the Rinnegan, it didn't matter at all.

"Execute!"

"Ding, the host has agreed to execute the Space-Time Mission."

"Space-Time Mission initiated."

"Space-Time Mission: Travel back to the Warring States Period."

"Space-Time Mission requirements: Within 30 days, take Senju Hashirama and Uchiha Madara as disciples, and raise both of their strengths to the Jonin level."

"Space-Time Mission buffs: Absolute Defense; Mangekyo Sharingan ability enhancement, unlimited use of Uhijini; exclusive ability—Bloodline Enhancement."

"Space-Time Mission modification: Host's age fixed at 20 years old."

"Mission reward: Six Paths Ninjutsu—Rinnegan."

"Space-Time regression."

In an instant, Uchiha Kei felt a powerful suction force appear before him, and a ghostly blue gate manifested out of thin air.

Uchiha Kei did not hesitate and stepped into the gate.

The moment he stepped inside, the ghostly blue gate vanished into thin air.

Hokage Building.

Sarutobi Hiruzen, who had been looking relaxed, suddenly stood up, his body tensing as he released his Kage-level chakra without reservation.

"Such eerie power. Has someone come to Konoha?"

Sarutobi Hiruzen looked solemn, his eyes fixed intently outside the window.

At the same moment, the heads of the major clans and Danzo all turned their gazes toward the interior of Konoha Village.

Konoha Village was on high alert!

Uchiha Kei had no idea how much of an impact the space-time regression had caused in Konoha.

After he walked through the gate, what appeared before his eyes was a lush, verdant forest, and many animals fled in fright upon seeing the human who had suddenly appeared.

"Is this the Warring States Period?"

Uchiha Kei looked around with curiosity.

From the Warring States Period to the establishment of the Ninja Village, and then through the Second and Third Great Ninja Wars, the world of Naruto had long since become riddled with holes; such pure, natural scenery had long since ceased to exist.

If nothing else, many of the animals that appeared here had long since gone extinct.

"Who... who are you?"

Not far away, a boy with a bowl cut looked at the young man who had appeared with a terrified expression.

Uchiha Kei turned his head and saw the bowl-cut boy.

Had he found one of the protagonists so quickly?

Senju Hashirama!

Uchiha Kei walked up to the boy. "Little one, is your name Senju Hashirama?"

The young Senju Hashirama looked wary and took a few steps back. "Yes, I am Senju Hashirama of the Senju Clan. How do you know my name?"

The little guy was quite vigilant.

However, Uchiha Kei understood that living in the war-torn Warring States era, where conflict could erupt at any moment, it would be strange if he weren't vigilant.

"My name is Kei. You can call me Teacher."

Uchiha Kei looked at the young version of Senju Hashirama with a smile.

Senju Hashirama during this period was not keen on strength; he was known as a good-for-nothing within the Senju Clan, and he was also incredibly naive.

If his father weren't the head of the Senju Clan, it would have been very difficult for such a Senju Hashirama to survive in this chaotic Warring States era.

"Teacher?" Senju Hashirama looked like a confused goose. "How can I call you Teacher? I'm not your student."

"Then why don't you just become my student?"

"Well, that makes sense. That way, I can call you Teacher."

The attribute of being a natural airhead was displayed to the fullest by Senju Hashirama.

"No, no, I don't even know who you are, why should I be your student?"

Senju Hashirama was merely airheaded, not stupid; after a moment of careful thought, he realized something was wrong.

"I told you, my name is Kei."

Uchiha Kei walked up to him with a beaming smile and placed a hand on top of his head.

"I can help you realize your wish for peace."

"Peace... can it really be achieved?"

Senju Hashirama instinctively wanted to dodge, but he was so captivated by Uchiha Kei's words that he forgot to move for a moment.

"Of course it can..."

Uchiha Kei was about to say more when he suddenly sensed something, a smile curling the corners of his lips.

"Hey! Let him go!"

On the other side, a spiky-haired youth ran over at high speed, glaring coldly at Uchiha Kei.

"Madara!"

Senju Hashirama smiled happily and was about to break free from Uchiha Kei to run over.

"Don't move!"

The spiky-haired youth roared.

Senju Hashirama, in his airheadedness, couldn't see it, but he could see it clearly.

The young man touching Senju Hashirama was terrifying!

He could feel an indescribable, unfathomable aura circulating around the young man.

Even his own father was far inferior to this aura!

"Who are you? Let Hashirama go immediately. I'm telling you, he is the young clan leader of the Senju Clan!"

During the Warring States Period, a time of raging flames, the Senju Clan and the Uchiha Clan were both renowned, top-tier major clans.

Ordinary people would give both clans a wide berth upon seeing them.

"I know," Uchiha Kei said in a flat tone. "I also know that your name is Uchiha Madara, and you are the young clan leader of the Uchiha Clan."

"You..."

Just then, a violent tremor shook the ground, and countless birds and beasts took flight in terror.

Uchiha Madara's expression changed drastically, and he shouted at Senju Hashirama, "Hashirama! Run!"

No sooner had he spoken than a massive, mottled tiger appeared in their line of sight, reeking of a pungent, bloody stench.

"ROAR!"

The giant tiger looked at its prey with excitement and charged forward with a howl.

Uchiha Madara and Senju Hashirama bolted toward the north at the same time.

Uchiha Kei watched the giant tiger with interest.

After the Ninja Village was established, such giant beasts were basically wiped out for the sake of the village's safety.

Seeing one now, Uchiha Kei was somewhat curious.

These naturally born beasts possessed no chakra and no ninjutsu; their means of attack relied entirely on their bodies and instincts.

Yet, it was precisely these beasts that caused immense damage to ninjas during the Warring States Period.

"ROAR!"

The giant tiger sprinted to Uchiha Kei's side, suddenly stopping in its tracks, looking at this "prey" with suspicion and hesitation.

Its instincts told it that the "prey" in front of it was not to be trifled with, as it exuded an aura that made the beast uneasy.

"Little one, are you afraid?"

Uchiha Kei was not worried in the slightest.

The system had stated he possessed Absolute Defense; he wouldn't even fear a fully grown Senju Hashirama or Uchiha Madara, so why would he fear a big cat?

Are you kidding me?

"Awoo!"

The giant tiger was somewhat startled.

Where did this person come from, and why did he feel so terrifying?

"You... you better run! This guy can even kill a Chunin!"

Senju Hashirama, who had run quite a distance away, had returned at some point and tried to pull Uchiha Kei along to escape.

Unfortunately...

He couldn't budge Uchiha Kei at all!
