"Of course, I'm a genius, so I'm an exception."
Renji stroked his chin thoughtfully.
"Logically speaking, this technique is very difficult to learn. After all, it's a ninjutsu without hand seals developed by the Fourth Hokage during his lifetime.
Its base power is A-rank, and the learning difficulty depends on talent."
"The Fourth Hokage?"
Team 7 looked surprised.
They had all heard of the Fourth Hokage.
He was the hero who once saved Konaha.
Since Rasengan was created by the Fourth Hokage, its difficulty was probably even higher than they imagined.
"Although its base power is A-rank, the number of people in the entire ninja world who can use Rasengan is extremely small."
Indeed.
Almost no one in the ninja world could use Rasengan.
It pushed shape transformation to its extreme.
Even Jonin found it difficult.
But the Nine-Tails brat would definitely learn it.
Naruto crossed his arms and looked at the Rasengan in Renji's palm before speaking dismissively.
"This crappy technique looks weak, and it's so hard to learn. Who would want to learn Rasengan? I'm going to become Hokage, so I need stronger techniques!"
He genuinely thought Rasengan looked weak.
It didn't look powerful enough to defeat enemies.
It barely looked strong enough to kill a chicken.
"That's why little brats are troublesome."
Renji walked toward a large rock and slammed the Rasengan into it.
The rock shook violently.
A whirlpool-shaped crater appeared at the impact point.
Naruto continued speaking confidently.
"See, Teacher Renji, I told you this technique was wea—"
Cracks suddenly spread across the rock.
Then the entire stone shattered into pieces and collapsed with a loud crash.
Naruto stared blankly.
"It broke such a huge rock. What a powerful technique!"
"Rasengan looks weak. It doesn't even have the impact of a woman shaking her chest, but it destroys targets from the inside."
Renji waved away the dust while coughing slightly.
"Cough, cough. I'm choking."
"Teacher Renji, please teach me Rasengan!" Naruto's eyes sparkled with excitement.
Rasengan was amazing.
If he mastered it perfectly, he could show it off in front of Sasuke.
Just imagining it felt exciting.
"Your attitude changes faster than a woman's."
Renji looked speechless.
Naruto mocked Rasengan one moment.
Now he desperately wanted to learn it.
Sakura raised her hand slightly and asked curiously.
"Teacher Renji, you said Rasengan is shape transformation. What is nature transformation?"
"They say big bears are brainless and flat bears are smart. You understand quickly," Renji glanced regretfully at Sakura's chest.
"Bastard."
Sakura's face turned red with anger as she clenched her fists tightly.
Calm down.
Calm down.
Calm down my ass.
"I was born smart. What does that have to do with having a small chest! Stinking rogue teacher, let me punch you!"
Sakura rushed forward angrily.
She hated being called flat-chested.
What was wrong with having a small chest?
She would definitely develop later.
"As adults, we all have strange habits, but I'm not a masochist. I'm the one who does the hitting."
Renji grabbed Sakura's wrist, flipped her to the ground with a swift grappling move, and gave her a sharp slap on the butt.
"Ugh, that hurts."
Pinned to the ground, Sakura glared at him angrily.
"I think you're a pervert who enjoys bullying girls!"
Renji thought for a moment.
"It is quite interesting."
"Pervert."
Sakura muttered angrily.
"Teacher Renji, ignore those two idiots and continue explaining nature transformation."
Sasuke spoke coldly.
He could clearly feel himself getting closer to power.
He had no time to waste.
"That's right. Getting stronger is important."
Renji raised a finger.
Pale blue Chakra gathered at his fingertip before turning into lightning.
"When Chakra is infused with an element after being released, that's called nature transformation. By adding Lightning Nature, Chakra becomes electricity.
Nature transformation is very convenient. I often use this ability to play with big sisters," Renji poked Sakura's waist with the electrified finger.
"Ugh."
Sakura's body trembled slightly.
Her face turned red.
The faint electric sensation spreading across her body felt strangely comfortable.
"It feels good, doesn't it, Lewd Brat," Renji withdrew his hand and spoke in a teasing tone.
"If you train properly, I'll teach you even more comfortable techniques."
"Pervert teacher, who wants that? Let me go!"
Renji released her.
"When you infuse elemental nature into Chakra and increase the amount, it forms a technique."
Renji raised his palm again.
Lightning gathered in his hand.
A sharp chirping sound echoed through the area.
"This technique represents the pinnacle of Lightning Release nature transformation."
"Chidori."
Lightning spread across the ground like blades, leaving deep marks behind.
"The developer is that dead-eyed guy, so remember the copyright."
"It looks so powerful!" Naruto stared excitedly.
Chidori looked much stronger than Rasengan.
Rasengan looked weak.
But Chidori looked amazing.
"Let's test its power."
Renji stabbed his lightning-covered hand through another large rock.
The rock shattered instantly.
Everyone inhaled sharply.
Chidori clearly had terrifying piercing power.
"Sasuke, Naruto, choose one technique to learn."
Renji raised both hands.
Lightning crackled in one.
Rasengan spun in the other.
