"What, are you deceiving me? The textbooks at the Ninja School never mentioned such a thing."
Sasuke deliberately provoked Kakashi.
Kakashi remained unfazed, his eyes squinting into crescent moons, laughing heartily while enjoying a vivid scene in Icha Icha Paradise.
But this kind of smile looked a bit lewd to Sasuke.
Is this guy really a Jonin?
Sasuke was a little unsure.
The book in his hand didn't seem very proper.
Kakashi put away the Icha Icha Paradise in his hand, slipped it into his Ninja Tool Bag, and focused his gaze on Sasuke.
"Alright, to prevent being called a liar, I'll show you a unique Secret Technique I developed myself. If you can master the basics I teach you, I'll pass this technique on to you."
"A unique Secret Technique? Can it defeat Itachi?"
Sasuke's eyes lit up as he asked eagerly.
"I don't know, I'm not very clear about the limits of Itachi's strength. I've never really faced him in battle. But he's an awakened user of the Mangekyo Sharingan, his strength defies common sense. The odds of victory are about fifty-fifty, I suppose."
Kakashi paused before answering.
"Mangekyo Sharingan..."
Upon hearing this particular term, a shadow crossed Sasuke's eyes.
If he remembered correctly, Itachi had said that to awaken the Mangekyo Sharingan, one must kill their closest friends.
Itachi killed Shisui, his companion like a brother, to awaken these eyes and gain forbidden power.
"Kakashi, what exactly is the Mangekyo Sharingan?"
Sasuke looked up and asked.
"As an outsider, I'm not well-suited to explain, and my knowledge about these eyes is limited. I only know it's a legendary power. When you awaken them one day, you'll understand what they are."
"I will never awaken those eyes."
Killing friends and such is sheer madness. Sasuke instinctively felt repulsed.
"Alright, watch closely now. This is the technique I'll show you next and will teach you in the future. Using this move makes defeating a Jonin not very difficult."
Raising his arm slightly, Kakashi continued talking to Sasuke while channeling Chakra into his palm.
Under Sasuke's astonished gaze, intense blue lightning gathered in Kakashi's palm.
It emitted a piercing sound like birds chirping, hurting Sasuke's eardrums and feeling grating.
"Amazing that Chakra can be materialized to this extent..."
Chakra materialization... isn't as simple as external release.
Sasuke knew that many Chunins couldn't achieve this; those who could were incredibly strong Jonin in the village.
Though he seemed like a pervert, his strength wasn't just talk! Sasuke no longer thought Kakashi was merely boasting.
"This is an A-Class Lightning Style Jutsu I developed around ten years old—Chidori. It's a Jutsu designed for high-speed assault on enemies, but due to the loud noise, despite its considerable power, without high-speed movement and strong Dynamic Vision, it's hard to hit the enemy. In the future, you'll awaken the Sharingan, which will significantly enhance your Dynamic Vision, making it easier to master this move by honing your Taijutsu."
Kakashi explained.
"Ten years old?"
Sasuke caught on to a shocking piece of information.
Developing an A-Class high-level Jutsu independently at ten?
This left Sasuke somewhat dumbfounded.
"Is there a problem?"
"I just find your talent astonishing, creating such a powerful Jutsu during the Ninja School days."
Sasuke said.
"No, by that time, I had already graduated from Ninja School."
"Hmm?"
"Though you might not believe it, I graduated from Ninja School at the age of five and passed the Chunin exams at the age of six, becoming a Chunin in the village."
Kakashi recounted his unremarkable ninja history.
"..."
Looking at Kakashi's calm demeanor, Sasuke thought, is this the frustrating face of a genius?
Sasuke felt an inexplicable frustration in his heart.
Compared to Kakashi, who graduated at five, became a Chunin at six, and independently developed an A-Class Jutsu at ten, he seemed a bit awkward.
Even his arch-nemesis Itachi hadn't accomplished such feats.
Following this man might really enable him to kill Itachi and restore the Uchiha's prestige! Sasuke was filled with eager anticipation.
Noticing the enthusiasm on Sasuke's face, Kakashi nodded in satisfaction, seeing that his provocation had some effect.
"Next up, is this."
Saying this, the lightning in Kakashi's hand became more solid, and emitted an intense aura, causing Sasuke's face to hurt as if pierced by something, making him instinctively step back a few steps.
Not only that, but the bird chirping sound vanished, and the lightning gathered silently in Kakashi's hand.
"This is..."
"It resembles Chidori in appearance, but they are two different Jutsu. Chidori is suitable for frontal assault, to distract the enemy. While this is the Lightning Blade, silent and perfect for assassination. To let you feel it directly, I let you experience its piercing aura, although there's no sensation when assassinating the enemy."
Speaking of which, the lightning's piercing sensation vanished from the air, and if not seen with his own eyes, Sasuke would think Kakashi was holding nothing.
Using this move to silently approach an enemy's back, Sasuke couldn't imagine the consequences.
"The focus of the two Jutsu is different. Choosing which to use depending on the battle situation can only be judged by your experience. Lastly, on this basis, is a derived Jutsu."
Kakashi suddenly waved his hand.
Sasuke only saw a flash of lightning, unable to track its trajectory.
Turning his head, he saw a row of trees neatly severed in the middle and collapsing on the ground.
The cut surface was smooth, like a polished mirror.
Moreover, when the lightning swept out, it made no sound, silent as a whisper.
"No need to be surprised, even though these Jutsu were developed by me, they aren't my strongest suit. What I'm most proficient in is refining the White Fang Swordsmanship passed down by my father."
Kakashi dispersed the lightning in his hand, placing it on the White Fang Short Knife's hilt behind him.
Sasuke glanced at it, unable to discern Kakashi's ability in swordsmanship.
"I won't demonstrate swordsmanship; for you, mastering the Lightning Style Jutsu I previously displayed is a prerequisite to studying the White Fang Swordsmanship under me. That's the foundation of White Fang Swordsmanship. And before that, understanding nature and clearing the mind of distractions is the foundational prerequisite. I've laid out the conditions, but they rely on your own training."
"I understand."
Though Sasuke tried to be calm, the fervor in his eyes couldn't be concealed.
After all... he still purely longs for power? Itachi's impact on him is too great. Kakashi thought to himself.
However, there's still plenty of time to refine Sasuke.
