Kazuku felt helpless.
Why did Tobirama pick this moment?
He had countless chances to teach Flying Thunder God before.
But he waited until now.
Right after Kazuku got it from the check-in gift.
Then he shows up to teach his "ultimate technique."
What…
Bad timing!
Tobirama's mindset was probably crumbling, right?
As expected…
When Kazuku threw the kunai, used Flying Thunder God to flash to it, and caught it…
Tobirama froze, staring dumbfounded.
His mind went blank, unable to accept reality.
Kazuku…
Mastered Flying Thunder God?
And after just one demonstration, he learned an S-rank technique Tobirama developed?
What a joke!
What kind of monster was he?
When Kazuku learned Eight Gates, it was shocking enough.
But…
While Eight Gates was powerful, it wasn't overly complex. With decent chakra control, even without precision, one could break physical limits to open the gates.
Kazuku's chakra control was exceptional, mastering monstrous strength.
Learning Eight Gates was naturally easier.
Though mastering it in one glance stunned Tobirama, it wasn't fundamentally impossible.
It just showed Kazuku's prodigious talent.
But Flying Thunder God was worlds apart from Eight Gates.
Its training difficulty far exceeded it.
And it was a space-time technique.
In Konoha, besides Tobirama, no one else knew it.
That alone proved its insane difficulty!
Yet…
You're telling me Kazuku mastered it after one look?
Impossible!
Tobirama rubbed his eyes, unwilling to accept it.
No matter how hard he rubbed, reality didn't change.
Kazuku…
Had indeed mastered Flying Thunder God!
"Body Flicker and Flying Thunder God look similar, but they're fundamentally different."
"Body Flicker gathers chakra in the feet for high-speed movement."
"Flying Thunder God is a true space-time technique!"
Tobirama gasped.
When Kazuku vanished, he didn't sense chakra in his feet.
Proof he didn't use Body Flicker!
"No, this isn't real…"
"Fake, fake."
"It's all fake."
"I must be in someone's genjutsu or still dreaming!"
Tobirama roared internally, denying Kazuku's mastery.
Even though his goal was for Kazuku to learn it, and fast…
Learning it in one glance?
He wouldn't accept it!
He couldn't accept it!
Did Kazuku know how long it took to develop Flying Thunder God?
How long to master it?
Compared to this seven-year-old, Tobirama felt like an idiot!
A failure!
A fool!
In his frenzy, Tobirama realized the core issue.
Yes.
Kazuku…
Was only seven!
Seven, and he mastered Flying Thunder God so easily. How terrifying?
How absurd?
"If I forgot everything about Flying Thunder God and relearned it, how long would it take?"
"One or two years?"
"Five or ten?"
The deeper he thought, the more Tobirama's mind exploded!
His mindset collapsed!
What God of Ninjutsu?
Compared to Kazuku's talent, he was the God of Failure!
After who-knows-how-long, with immense effort, Tobirama barely calmed down.
But his shock over Kazuku lingered.
"Ka-Kazuku…"
"Don't tell me you learned Flying Thunder God from one glance!"
Unknowingly, when he spoke again…
His voice trembled!
Kazuku's Flying Thunder God left such a psychological scar!
Now, he seriously doubted his own abilities.
Seeing Tobirama so unconfident, Kazuku's mood turned complex.
He was his second grandfather, after all.
Kazuku had a hunch. If he said, Flying Thunder God? Piece of cake. I learned it in one look!
Tobirama might faint on the spot.
For Tobirama's sake, Kazuku's mind raced for two seconds. He opted for a white lie.
"Well, not exactly."
Kazuku waved the kunai. "Grandpa Tobirama, remember this?"
"Hm?" Tobirama's eyes narrowed, seeing the pristine kunai.
Wasn't this the kunai he gave Kazuku as a gift after defeating Danzo?
Anything about Kazuku, he'd never forget.
"When I got it, I noticed strange patterns on it."
"Strange patterns?" Tobirama thought, likely the Flying Thunder God seal.
"Out of curiosity, I studied it." Kazuku took a deep breath. "And learned Flying Thunder God."
Tobirama: "???"
Kazuku's casual words hit like a thunderbolt.
He stumbled back a step.
If Kazuku learned it from his demo and explanation…
It'd mean his talent, comprehension, and mimicry were extraordinary.
Though impossible in Tobirama's view, Kazuku doing it just proved his brilliance.
Some geniuses achieve the unthinkable!
But Kazuku said he didn't learn it from the demo or explanation.
He learned it before?
From just seeing a Flying Thunder God seal?
So…
Kazuku practically reinvented Flying Thunder God?
What a joke!
No!
Impossible!
I won't accept it!
Fake, fake, it's all fake!
I'm in an Uchiha genjutsu!
Could it be Izuna?
Did I not kill him with Flying Thunder Slash?
Was I trapped in his Mangekyo Sharingan genjutsu from the start?
Tobirama even heard a phantom voice.
Tobirama, when did you think this wasn't a Mangekyo genjutsu?
