"When this old man says something, it's a promise I won't break."
Senju Tobirama raised an eyebrow in good spirits, "Kid, this time I'll teach you a Kinjutsu!"
"Unlike that theoretical 'Will of Fire' of yours, my broader perspective allows me to teach even a forbidden technique to a wicked little Uchiha like you..."
Senju Tobirama chuckled.
Aomi frowned slightly; this behavior from Senju Tobirama was exceedingly abnormal.
Having known him for so long, Aomi could assert that the old man was definitely up to something!
This expression and demeanor were exactly like when Aomi planned to prank Tobirama; others might not see it, but Aomi certainly did...
Tobirama, seeing Aomi's furrowed brow, spoke slowly, "The Jutsu I wish to teach you is a Kinjutsu I developed independently: Tandem Paper Bomb Jutsu!"
"I've classified its Ninjutsu level as A-Class. The principle is to continuously summon Explosive Tags, focusing on a single point for successive detonations..."
"Its power is such that even the Tailed Beasts would find it hard to withstand when used properly!"
Aomi blinked; he indeed knew this Tandem Paper Bomb Jutsu...
As Aomi pondered over Asuma, Senju Tobirama sensed something amiss and proactively mentioned the previous bet, requiring Aomi to agree to his terms and not harm Konoha if he lost.
And Aomi's response was: "Even if I win, you have always been my idol, and I won't make you grovel, for I'd feel bad about it..."
With gentle words, he successfully challenged him with the Tandem Paper Bomb Jutsu.
Since mastering the Jutsu, Aomi hasn't had the chance to study it.
Firstly, it's hard to explain its origin, as the sharp-minded Tobirama might notice something unusual, which could create a rift, making it difficult to borrow his strength in the future.
Aomi considered Torama Jutsu to be far superior to the Tandem Paper Bomb Jutsu...
Secondly, the Jutsu must be used as a set; otherwise, it's merely mutual destruction through self-detonation.
Reanimation Jutsu must be mastered to use the immortal Reanimated dead as a suicide squad to continually adjust subsequent summoned Explosive Tags for precise enemy targeting during the explosion...
Otherwise, mastering this Jutsu on its own is of little use.
Besides this, Aomi, understanding the mechanism of the Tandem Paper Bomb Jutsu, guessed Tobirama's real intention...
He most likely wouldn't tell Aomi how to sense the space where he stored the Explosive Tags.
In this way, the Kinjutsu, while incomplete and limited in use, combined to act as a double insurance, ensuring that even after Aomi learned it, it would be as if he hadn't...
"Old man, you're really good at this, stacking two layers of insurance together; you're truly an evil Senju old ghost..." Aomi teased inwardly but then couldn't help but secretly laugh.
Indeed, while the Jutsu Tobirama chose seemed useless, the issue lay in...
What if, to Tobirama's surprise, Aomi created his own space for Explosive Tags without his guidance...?
What would the Second Hokage think then?
Some people might be quite confused!
Aomi stifled his laughter, allowing a bit of anticipation and joy to show in his eyes, addressing him respectfully, "I've heard of this Jutsu. I want to learn it, Tobirama-sama!"
"Hmm..." Senju Tobirama grunted, nodding appreciatively.
Tobirama-sama...
To be honest, the way this little Uchiha kid called out was rather pleasant to the ears!
Good to hear, great to listen to!
"Since you're so earnest, this old man will reluctantly teach you this Kinjutsu..."
Senju Tobirama put on a show, feeling pleased inside.
The wicked little Uchiha used to mock the 'Will of Fire' I had as zero marks?
Fine, go ahead and mock, but when you can't master this trick, I'll have my turn at mocking!
What, can't even wield the Jutsu I so patiently taught you?
And you call yourself a genius? You're just a big fool!
Senju Tobirama controlled his emotions well, displaying the professionalism of the First Ninja School Principal, as he entered teaching mode.
"The first step is to prepare a large quantity of Explosive Tags." Aomi's brow twitched as he whispered, "Tobirama-sama, where do I get such a large amount of Explosive Tags?"
"Can't you just order the military factories of the Land of Fire and the ninjas working underground? Or, have the ninjas from your clan cooperate, and you should be able to gather enough in a few months." Senju Tobirama stifled his laughter. Why did he have access to so many Explosive Tags back then?
Wasn't it because he was the Second Hokage!
Even back in the Warring States Era, as the leader of the Senju Clan, he could spend money however he liked!
This Jutsu might as well be called 'prepare in advance with resources and then bombard you' technique instead of Tandem Paper Bomb Jutsu...
"Alright, once this step is completed, then mark these Explosive Tags with a Summoning Contract and transport them into an Alternate Space for storage!"
"The third step, and also the last, is to create Summoned Creatures that can be interconnected with the quantity of Explosive Tags, serving as the trigger for the Jutsu." Senju Tobirama, with a wave of his hand, quickly and concisely explained this A-Class Kinjutsu, the smile on his face unhidden:
"We'll proceed step by step, make sure you have enough Explosive Tags ready..."
"Don't worry, little Aomi, I'm guaranteeing you will learn it unless you're exceptionally dull, in which case this old man wouldn't be able to help."
"Oh, right... I forgot to mention, this Jutsu is quite dangerous and also requires pairing with the Reanimation Jutsu to safely perform it—otherwise, it poses a lethal threat to the caster and dissipates the Jutsu's power..."
"No worries, first master this Jutsu; as for the Reanimation Jutsu..."
"Opportunity might arise, then this old man might teach you?"
While Senju Tobirama spoke, watching Aomi's puffed little face, he laughed heartily.
Who said only the Uchihas could have a mad laugh! My Senju laughter can also be quite resonant!
In this moment, Senju Tobirama finally felt he wasn't the fool with zero marks in the 'Will of Fire' but rather the Second Hokage with a clever hand!
"Hey, that's too sneaky!"
Aomi protested, dissatisfied: "Overall, you should at least teach me how to establish and sense the storage space, right? Or, are you afraid I'll find the space where you've hidden those Explosive Tags…""
"Don't try to provoke me, kid. I was planning to teach you that myself."
With an air of certainty, Senju Tobirama crossed his arms: "But my Explosive Tags space is mine. If you have the ability, establish one yourself..."
"Watch, use your senses, form these Hand Seals, and move your Chakra carefully through your pathways..."
Senju Tobirama explained it without any reservations.
There was absolutely no way Aomi could connect to his Summoning Space; in fact, no one could do it aside from him!
If anyone could sense it, would it not mean preparing a stockpile of Explosive Tags for the enemy?
No way would Senju Tobirama do something so as self-sabotaging as lifting a stone only to drop it on his own foot...
Then, as he watched.
Aomi carefully formed the hand seals, closing his eyes slightly, actually managing to summon a single Explosive Tag in his hand, "Tobirama-sama, is this how it's done?"
Meanwhile, Senju Tobirama, with arms crossed, nodded unexpectedly, "Indeed, it is done this way..."
But shortly after.
Senju Tobirama seemed to sense something wasn't quite right...
