Ten Times Feedback! Rasengan's S-Rank Version!

After listening to Orochimaru's analysis and vision, Xu Ming was left in shock.

What's up with this kid?

Did he somehow surpass Namikaze Minato?

Xu Ming found the whole situation utterly absurd. While Orochimaru's idea wasn't entirely correct, it was remarkably close to the final answer—at least 70% accurate!

He realized that he didn't even need to intervene. Given a little more time, Orochimaru would likely figure out the remaining key aspects on his own.

"How about it?"

Orochimaru finished speaking and stared at Xu Ming intently, anticipation burning in his eyes.

"Your idea is solid. I think you should give it a try in this direction," Xu Ming responded after a moment of thought, offering an encouraging smile.

He couldn't afford to dampen Orochimaru's enthusiasm.

In fact, he had to encourage it—strongly!

Ideally, he wanted Orochimaru to fall in love with this process, staying up late every night to practice. If there were new techniques, he should learn them; if not, he should refine and perfect the existing ones.

After all, if Orochimaru took off, Xu Ming would soar straight into the stratosphere.

"I see," Orochimaru murmured.

Little did Xu Ming know, his encouraging smile only deepened Orochimaru's misunderstanding.

'So, Xu Ming is testing me after all.'

'I don't know why, but I refuse to be underestimated.'

Determined, Orochimaru ignored the rest of the lesson, narrowing his eyes in thought as he focused entirely on the fourth stage of Rasengan's development.

Lunch Break

Xu Ming noticed that Orochimaru remained glued to his seat, deep in thought.

"Tsk, tsk, tsk…"

Tsunade approached, shaking her head in disbelief.

"Xu Ming, did you put Orochimaru under a genjutsu? He's been obsessing over you all day."

"It's the first time I've seen him this fixated on something," Jiraiya added, walking over curiously.

Neither of them asked about Xu Ming's new technique.

To them, ninjutsu was a highly secretive and valuable discipline. Even among friends and teammates, it wasn't something to inquire about casually.

"The more effort you put in, the more likely you are to see results." Xu Ming shrugged with a knowing smile. "Just wait—you'll be surprised."

"So confident?" Tsunade raised an eyebrow.

"No way… Did you actually develop a new technique?" Jiraiya looked skeptical.

Xu Ming simply shrugged, maintaining a mysterious air.

Without another word, he turned and walked away, leaving only an enigmatic silhouette behind.

Three Days Later – Ninja School Break

That afternoon, Orochimaru sat in his room, deep in thought. He crumpled yet another piece of paper and tossed it into the trash.

"Haah…"

He exhaled wearily, rubbing his temples.

Three days had passed. He had thought of countless solutions, yet none seemed quite right.

"Maybe I need to start over and analyze everything from the beginning?"

Orochimaru stared at the ceiling, lost in contemplation.

"Xu Ming said this technique was inspired by the Tailed Beast Bomb. It's a purely non-elemental chakra technique, achieved by removing Yin and Yang chakra while perfecting its form transformation."

"Without the opposing forces of Yin and Yang, there's no explosion."

"That means the Rasengan's destructive power must come from something else."

Suddenly, his eyes gleamed with realization.

He recalled the third stage of training.

Once chakra was fully materialized, the resulting turbulence could carve spiral-shaped cuts into tree trunks.

"That means the Rasengan's lethality comes from the high-speed rotational turbulence, which acts like a powerful grinding force."

"A similar effect can be seen in the Second Hokage's Water Release: Water Severing Wave technique."

"So, how do I enhance this grinding effect?"

Orochimaru glanced at his palm, deep in thought.

Then, in a flash of inspiration, he grabbed a pen and marked a single point on his palm—just as he had done in the first stage of training.

Whoosh!

Chakra surged from his palm—gathering, compressing, and materializing!

This was the result of his training up to the third stage.

But this time, Orochimaru didn't stop there.

He continued compressing the chakra further, forcing the high-speed turbulent currents to converge toward the marked point, forming a vortex-like eye—similar to the calm center of a typhoon.

Whoosh!

Instantly, the entire chakra sphere solidified, taking on a crystalline-like structure.

The surface became eerily smooth, forming a perfect outer membrane.

At its core, a massive concentration of chakra swirled violently, like a miniature supernova.

"It worked!"

Orochimaru's heart pounded with excitement.

Without hesitation, he rushed to a nearby wooden training post and pressed the chakra sphere against it.

CRACK!

The moment it made contact, the wooden post shattered completely, bursting into fine sawdust.

"Hiss…"

Orochimaru took a sharp breath, staring at the destruction in shock.

"Just by adding a small step to the third stage, the power increased more than tenfold?"

"What a terrifying technique!"

"If this hits a human body, their flesh would be ground into pulp in an instant!"

Meanwhile…

At that exact moment, a new system prompt appeared in front of Xu Ming.

[You have perfectly mastered the Nature Transformation of the A-Rank Muji Rasengan. You can now infuse additional elements, such as Wind Style, Fire Style, Lightning Style, Magnet Style, Lava Style, and even Sage Chakra.]

[You have mastered A-Rank ninjutsu—Big Ball Rasengan!]

[You have mastered S-Rank ninjutsu—Wind Style: Rasenshuriken, Lightning Style: Hidden Thunder Orb, and Fire Style: Blazing Flame Rasengan!]

Three notifications popped up in quick succession.

Xu Ming was so stunned that he rolled off his bed.

Although he had anticipated the system's tenfold feedback, he hadn't expected it to be this insane!

Not only had he perfected the Rasengan's Nature Transformation, but he had also instantly mastered three S-Rank variations—each of which had appeared in the original timeline.

Since Rasengan was already an A-Rank technique, combining it with elemental transformation had elevated it to an S-Rank jutsu, putting it on par with Forbidden Techniques.

"Wait… My chakra nature includes Wind, Lightning, and Fire…"

A realization struck him, and his expression changed dramatically.

"I see now! The system grants me mastery over Rasengan variations based on my natural chakra affinities!"

Though he considered himself an average talent, the fact that he was placed in the same class as the future Sannin meant he couldn't be ordinary.

The elite Class 1 of the Ninja Academy was reserved for exceptional students.

For example, Orochimaru was born with four chakra natures. Jiraiya had all five elements. Tsunade, a Senju, possessed monstrous physical strength and resilience.

Compared to them, Xu Ming—who was born with three chakra affinities—was merely average by their standards.

But with the system's help…

He was anything but ordinary.
