Tobirama Senju: I'm Super-Doubling My Generation! (Tuesday PK, seeking reads!)

"You're certainly willing to go to extremes; you even burned down your own old house just to trap me."

Uchiha Shingen turned his head at the sound.

He saw Setsuna Uchiha slowly rolling toward him in a wheelchair.

With one hand clutching a wooden box to his chest and the other resting on the wheelchair, he felt sheer delight at seeing Uchiha Shingen frustrated:

"That house was already falling apart anyway. Everything inside had either been moved or ruined by the erosion of time."

"Keeping it was just an eyesore."

"It was better to burn it all down; at least it provided this Old Man with some amusement."

Setsuna Uchiha pointed a finger at Uchiha Shingen and laughed:

"I felt a bit of heartache at first, but now, this Old Man thinks it was worth it!"

"Honestly..."

Uchiha Shingen shook his head, feeling quite helpless regarding the old man's style.

Not long ago, the Setsuna Uchiha he knew was still the powerhouse who had stood toe-to-toe with the Second Hokage, Tobirama Senju, a major figure destined to stir up trouble after his release from prison.

Who could have known he would turn out to be such a malicious old geezer!

"Catch."

Seeing that the timing was right, Setsuna Uchiha casually tossed the wooden box toward Uchiha Shingen.

Uchiha Shingen instinctively reached out and caught the box.

He weighed it in his hand; it was heavy, and an inexplicable chill radiated from within.

Even with his current strength, the hairs on the back of his hands stood on end, and he had the distinct illusion of being sliced by a sharp blade.

This sensation made Uchiha Shingen's eyes narrow as he reached out to open the lid.

Inside lay a long sword, simple in design yet clearly no ordinary weapon.

The chill he had felt earlier was indeed emanating from the blade itself!

"This is..."

"This fellow is called Kotetsu."

The smile faded from Setsuna Uchiha's face, replaced by a touch of seriousness:

"Kotetsu was once the personal blade of Lord Izuna. After Lord Izuna passed away, it eventually fell into my hands and accompanied me through countless battles."

"It's a pity that this Old Man is now crippled and a useless person; naturally, I can no longer take it into battle."

"Consider this a welcoming gift for my disciple."

At this moment, Uchiha Shingen's gaze was completely captivated by Kotetsu.

He had seen many high-performance weapons before.

But neither the short blade Kakashi inherited from White Fang, nor the Flying Swallow twin blades in the hands of Sarutobi Asuma, had ever given him such an illusion.

Just looking at it had a magical quality that made one feel as if they were trapped in a genjutsu.

"Good stuff!"

"Of course it's good stuff!"

Seeing his reaction, Setsuna Uchiha felt quite proud:

"The quality of this blade is not inferior to the seven swords of Kirigakure; it might even surpass them."

"I recall you were using Shadow Clone to train, right?!"

"Yeah."

Uchiha Shingen replied without looking up:

"Although it puts a lot of pressure on the body, the efficiency is fast enough."

"Create one more clone later; this Old Man has new things to teach you."

Setsuna Uchiha reached up and stroked his white beard.

He then remembered that before deciding to pass on his mantle, Uchiha Shingen had already become a disciple of Jiraiya.

He immediately snorted, sounding quite arrogant:

"It won't be any worse than what Hiruzen's disciple taught you..."

As he spoke, Setsuna Uchiha suddenly realized something was wrong:

"Wait a minute!"

"You are Jiraiya's disciple, which makes you the grand-disciple of Tobirama Senju?! If we calculate it that way, doesn't that make me two generations younger than Tobirama Senju?!"

At the mention of the Second Hokage, Tobirama Senju, Setsuna Uchiha's old face instantly soured:

"Give the sword back; I'm not taking this disciple anymore."

"What was that, old man? I'm hard of hearing, speak up!"

Bang!

Uchiha Shingen nimbly snapped the wooden box shut and hurried up to the second floor, leaving Setsuna Uchiha with nothing but a dashing view of his back.

"That brat..."

Setsuna Uchiha shook his head, though he couldn't suppress the corners of his mouth from curling upward.

So what if the generation gap was a bit short? It wasn't as if he could argue with a dead man, could he?

The one who survives is the winner, wouldn't you agree, Tobirama Senju?

Click!

Closing the door behind him.

Uchiha Shingen placed the wooden box on his desk, rubbed his hands together, and opened it once more.

The silvery, gleaming blade of Kotetsu reflected his face, and even more so, the excitement in Uchiha Shingen's eyes.

He knew that in his previous battle against Kakashi, he had suffered a major disadvantage because he lacked a sufficiently good blade, leaving him suppressed by Kakashi's White Fang short blade.

Later, when he wanted to test the power of Sword Leap Flame, he had to give up because the kunai couldn't withstand the high temperature.

He had been forced to switch to large-scale ninjutsu to end the fight.

But now, with Kotetsu in his possession, everything would be different; he would be able to completely suppress Kakashi right from the start of the battle.

Tap!

Uchiha Shingen reached out and gripped the hilt of Kotetsu, and a strange chill immediately emanated from the blade.

The hallucination he had felt just a moment ago reappeared before Uchiha Shingen's eyes.

He saw the final expressions of one person after another who had fallen to this blade, saw the disbelief in their eyes, saw the spraying blood...

It wasn't until a silver-haired man appeared in the vision that it all came to an end.

"Is this everything Izuna Uchiha experienced? No, it should also include the old man's experiences."

Uchiha Shingen realized this, but more questions flooded his mind:

"But..."

"Why does a sword have abilities akin to genjutsu?!"

"Surprised, are you?!"

The locked door had been pushed open at some point. Setsuna Uchiha sat in his wheelchair, his gaze fixed on Kotetsu with a hint of reminiscence in his eyes as he said:

"This blade was forged from special materials and possesses extremely powerful performance. Even in terms of pure sharpness, it is enough to stand alongside the seven ninja swords of Kirigakure."

"But more importantly, it gradually becomes influenced by its master's abilities, eventually developing similar traits."

Uchiha Shingen immediately recalled the hallucination from just moments ago; that feeling was almost indistinguishable from being caught in a genjutsu.

"So, old man, are you actually a master of genjutsu?!"

"No, that's not right. Uchiha genjutsu is primarily based on ocular jutsu. It's impossible, and unnecessary, to cast genjutsu through a sword..."

"..."

Mid-sentence, Uchiha Shingen's words came to an abrupt halt. He suddenly realized he had fallen into a trap of his own logic.

Who said that Uchiha genjutsu must be ocular jutsu?!

"Have you realized it?!"

"You brat!"

Setsuna Uchiha nodded slightly, becoming increasingly satisfied with his disciple. Even the frustration of being dropped two generations in status was significantly diluted:

"What do you think is the most important aspect of genjutsu?!"

"Concealment."

Uchiha Shingen gave his answer. Recalling his successive battles with Obito and Kakashi, his vision suddenly cleared:

"Situations where you can dominate an opponent with genjutsu at a single glance only occur when there is a massive gap in strength, but in those cases, it makes little difference whether you use taijutsu, genjutsu, or ninjutsu."

"When strength is comparable, the opponent will inevitably be on guard against the Sharingan, and the success rate of ocular jutsu will not be very high."
