All right, Obito, don't be discouraged. Try harder next time,"
Iruka-sensei said, checking Obito's condition. Fortunately, they were only light injuries.
"Hmph! I just didn't perform properly today!" Obito snapped.
Just thinking about embarrassing himself in front of Rin made him burn with frustration.
"It's okay, Obito. You've already worked really hard."
Nohara Rin gave him a warm smile.
The moment Rin comforted him, Obito's angry face turned sheepishly smug again.
"Raizen not choosing to train taijutsu with me is such a shame!"
Might Guy lamented dramatically.
"If he joined me in the training of youth, he'd definitely achieve great results!"
"No… training with you would ruin him," Kakashi muttered.
Just imagining an Uchiha wearing a green jumpsuit and rocking a bowl-cut hairstyle made Kakashi shiver.
"Uchiha Raizen… I'll keep watching him for a while."
Kakashi's eyes narrowed thoughtfully.
He was tired of the petty scuffles at the academy.
The thought of graduating early grew stronger by the day.
His father, the legendary White Fang, was known throughout the ninja world....yet here he was, wasting time.
Before he even enrolled, at age four, Kakashi could already perform Earth Style: Earth Wave.
He'd even taken first place in a jutsu-release competition and received a silver kunai as a prize.
"If Raizen can graduate early too… being paired with him wouldn't be bad," Kakashi murmured.
Meanwhile, Raizen returned to the crowd, responding politely to those who approached him.
The Lightning Style: Iron Body technique was incredibly effective.
He could feel himself developing faster.
During his fight with Obito, Raizen clearly noticed he was more agile than yesterday.
The technique allowed lightning-nature chakra to gather beneath the skin and flow through specific muscle fibers at a precise frequency.
The electric current stimulated fast-twitch muscle fibers, activating protein synthesis within them....causing the muscle cells to expand rapidly.
In short, his training efficiency skyrocketed.
The drawback was that it did little for his organs or bones....just toughened his skin and boosted surface-level endurance.
For now, that was more than enough.
He hadn't mastered the technique yet....he was only applying the method to small sections of muscle based on the scroll's instructions.
Once he fully learned it, Raizen's body would grow stronger at a shocking pace.
Iruka began calling the next pair for sparring.
Raizen, hidden within the crowd, quietly resumed his subtle practice of Iron Body, guiding lightning chakra through his body.
If someone used Byakugan to observe his chakra network, they'd see faint currents radiating from his meridians, spreading outward.
He was growing stronger....bit by bit.
Right now, Raizen could easily defeat the version of himself from just one month ago.
Dusk.
The Third Training Ground was still busy, figures casting long shadows.
Near a small river at the edge of the field...
"Today, we're learning how to walk on water."
Rin explained the principles to Raizen.
Kakashi and Obito were there as well.
Obito crossed his arms and deliberately stood farther from Raizen, edging closer to Rin.
Kakashi, expressionless behind his mask, listened quietly.
He already knew everything Rin was explaining.
He had shown up every day for one simple reason:
Raizen improved every single day.
Sometimes, consistent improvement was its own form of talent.
Many people trained hard only to hit bottlenecks....but Raizen advanced with terrifying smoothness.
"I wonder how Raizen will handle this… water walking is far harder than tree climbing," Kakashi thought.
Tree climbing only required gathering the right amount of chakra and maintaining it.
Trees didn't move...so as long as one could stick to the surface, it was enough.
It was the foundation of being a ninja: generating and controlling a stable amount of chakra.
But water walking required continuously releasing chakra from the feet...precisely balancing it so one didn't sink or blast the water apart.
It demanded long-term stability and delicate control.
"Ninja usually refine chakra while constantly moving. This makes 'controlling' and 'maintaining' chakra much harder, so basics are essential," Rin explained seriously.
She'd obviously paid attention in class.
"Oh… so that's how it works."
Obito blinked, realizing Rin had just explained a lot of things he had never really understood.
He glanced at Kakashi.
Kakashi didn't react....meaning he already knew all of it.
Then Obito looked at Raizen.
Raizen seemed deep in thought.
Oh no… is he the only one who doesn't get it?!
Obito's heart tightened.
He decided he would study hard at home later.
"I'll demonstrate first," Rin said.
She removed her shoes, stepping onto the gently flowing surface of the river.
Small ripples spread beneath her feet.
She walked several steps, perfectly stable.
"Taking off your shoes makes it easier," she added.
Barefoot, you only needed to focus chakra into the soles.
Shoes added thickness and interfered with the chakra flow.
"Got it."
Raizen walked forward, removing his Uchiha robe so only his long-sleeved inner shirt remained.
He formed hand signs, gathered chakra, and stepped toward the water.....
attempting water walking for the first time.
