Tobirama Senju Declared He Never Plagiarized, Uchiha Yashiro Attacked

Seisui's training ground.

Seisui held Muramasa, locked in combat with Shisui, who wielded two small tantō.

"Idiot, leave three-tenths of your strength when swinging, unless you're sure you can kill your enemy in one strike..." Seisui said with a faint smile, casually deflecting Shisui's twin blades before slashing sharply toward his face.

Shisui's swords were knocked outward, and Seisui's blade carried a biting wind, reaching his face in an instant...

Shisui strained to activate his Sharingan, but unfortunately, the Double Tomoe's enhanced dynamic vision only let him barely track Muramasa's arc—his body lagged behind his eyes, leaving him to watch helplessly as the blade came down!

The edge stopped about a centimeter from Shisui's forehead.

Seisui grinned at him and said softly, "See? If you hold back, when your attack is blocked, you have strength left to defend. You won't end up completely passive..."

"Especially as a ninja, with all kinds of techniques to blind your opponent, going all out is never a good idea."

Shisui's forehead slowly dripped cold sweat as he nodded seriously. "I understand, big brother."

At that moment, Shisui felt both grateful for having such a strong and patient brother to guide him and a little disheartened.

He thought his swordsmanship talent was excellent, but before Seisui, it was riddled with holes.

What Shisui didn't know was that while he thought he was sparring with Seisui, every exchange was actually a battle against Tobirama Senju.

And Tobirama Senju—this was a man who grew up trading blades with the Uchiha killers of the Warring States Period, who had crossed swords over a thousand times with Uchiha Izuna, second only to Madara Uchiha. A true hardcore badass.

The swordsmanship he developed embodied his own sharp, practical, and ruthless style, blending Genjutsu and Chakra blades into one—a perfect tool for murder, robbery, and wiping out families!

Especially when dealing with Uchiha, Tobirama had even exploited the delay between the Sharingan's dynamic vision and the brain's reaction, deliberately crafting several killing moves...

And in Seisui's hands—a Double Tomoe Uchiha with abundant Dojutsu—this style could be practiced forward or backward with equal mastery, filling in the gaps left by Tobirama's lack of a Sharingan.

"I think I know where you got my techniques from... Since you're Kagami's descendant, I taught him swordsmanship. My Water Release and Genjutsu were copied by those Uchiha too. With your talent for developing forbidden techniques to seal my soul, this isn't surprising."

Tobirama studied him carefully for a long time, first saying a few words, but when Seisui didn't respond, he fell silent for a moment before finally asking:

"But are you using my swordsmanship, or Uchiha Izuna's fighting style?"

When Seisui was instructing Shisui, Tobirama first saw his own shadow and smugly thought Seisui had seen the light, favoring his style over Uchiha swordsmanship.

But slowly, his expression froze. Seisui's blade work shifted to something purely Uchiha—so much like Uchiha Izuna!

By the end, even Tobirama himself was confused.

In truth, Uchiha Izuna and Tobirama Senju's swordsmanship styles, even their moves, were very similar.

Both were calm and ruthless characters. The only clear difference was that Tobirama was better at reading people's minds, while Izuna, with his Sharingan as a feint, was a bit more reckless.

Seisui blinked and couldn't help but sigh. The eternal problem of the ninja world always seemed to be bonds.

Hashirama Senju and Madara Uchiha, the reincarnations of Ashura and Indra, went without saying. But the intense bond between Uchiha Izuna and Tobirama Senju was no weaker than their brothers' thousand-year struggle.

For instance, someone as sharp and calm as Tobirama couldn't suppress his burning curiosity when it came to Uchiha Izuna...

"Does it matter, Tobirama? I've noticed an interesting question. I've studied both your swordsmanship styles, and they overlap a lot—even the philosophies are the same..."

"The only difference is probably the presence or absence of the Sharingan. So I'm wondering, did you borrow from Uchiha Izuna's style, or did he..."

Before Seisui could finish, Tobirama cut in urgently:

"Of course he copied me! Look at the result—my Flying Thunder God Slash beat him easily, didn't it? In the ninja world, there's no way the winner copies the loser!"

Tobirama spoke with righteous indignation, but there was a faint hint of unease in his voice.

Seisui caught it sharply and nodded with a smile. "Right, right, Tobirama's always right... The Flying Thunder God Technique definitely wasn't something you invented because your swordsmanship couldn't beat Uchiha Izuna..."

"Oh, it's no big deal. All techniques and swordsmanship in the world are copied back and forth—that's how they improve! Admit it, Tobirama, it's not shameful. Our Uchiha Clan's Sharingan even copies things..."

"It's not nothing! I'm different from you Uchiha. I use my own swordsmanship, my own techniques. I didn't copy that bastard!"

Tobirama was unusually fixated on this, emphasizing it heavily.

But the electronic sound in Seisui's head seemed to give the answer: From target Tobirama Senju, you have gained enhanced motor nerves!

Seisui smiled and waved at Tobirama, bidding farewell to the Second Hokage, who seemed ready to argue for five hundred rounds to sort out the details. He quietly felt his body growing more agile while explaining the essence of swordsmanship to Shisui.

Fleece-pulling—Seisui had figured it out.

For someone as guarded as Tobirama, you had to take a casual approach, grab what you could, and never rush it or risk backfiring.

After all, Konoha still had the pair of geniuses Shimura Danzō and Hiruzen Sarutobi, who would eventually pull off some miraculous moves that would make Tobirama's eyes roll back and cough up a fortune.

"It's okay, Shisui. If you don't get it, big brother can teach you again..."

Seisui gently patted the sweating Shisui. His swordsmanship, derived from Tobirama and improved upon, was still a bit too advanced for a six-year-old.

Just as Shisui nodded seriously.

A gray-haired, sturdy adult ninja walked into Seisui's training ground and spoke: "I have some insights into swordsmanship too, Seisui Uchiha. If you have the courage to face me, let's exchange a few moves."

As he spoke, a pair of crimson Three Tomoe Sharingan slowly spun in his eyes.

This man was well-known in the Uchiha Clan.

His name was Uchiha Yashiro, a long-established Three Tomoe Jonin in the clan and a die-hard member of the Hawk Faction!

Can't sleep...
