Vanishing Rasengan

"Finished... so this is it..."

"Sasuke's signature move, Chidori?"

Gazing at the highly concentrated, violent electrical current in his left hand.

Yu could feel every cell in his body being stimulated and activated by this powerful Lightning Release chakra.

Swish!!

As the words left his lips, Yu's figure transformed into a bolt of lightning, vanishing from the spot in an instant.

Boom!!

In the blink of an eye, a thunderous explosion rang out as Yu's figure reappeared.

The large tree ten meters away had been blasted in two by the screeching Chidori in his hand.

"Such immense power..."

The violent current in his hand gradually dissipated.

Looking at the massive destruction caused by the Chidori, Yu couldn't help but marvel.

However, feeling that over half of his chakra had been consumed in an instant, a wry smile appeared on Yu's face.

"But this chakra consumption isn't something an ordinary genin could withstand."

Even though he had broken through to the genin level of chakra.

And having been modified by the power of the String-String Fruit, his body was no longer that of an ordinary human, giving him several times the chakra reserves of a standard genin.

Yet, Chidori, a forbidden-level, ultra-high-tier Lightning Release ninjutsu, still drained over half of his chakra in a single use.

One had to remember that even Sasuke, during the Chunin Exams in the original story, could only use Chidori twice a day.

"Tsk, tsk, tsk..."

"Such outstanding talent and perseverance..."

Seeing Yu's remarkable talent and astonishing willpower, the devil clicked its tongue in admiration. "I'm starting to like you..."

"Like me? Give me a break..."

"Didn't you say you wanted to devour my soul just the other day?"

Hearing the devil's bewitching and seductive words in his ear, the wry smile on Yu's face deepened; he wasn't foolish enough to take the devil's words at face value.

"Cackle, cackle... that depends on whether you can successfully survive in this world."

Hearing Yu's retort, the devil burst into continuous, cackling laughter. "It wouldn't hurt to tell you the truth: you aren't the first host to awaken me in this world."

"It's just that the previous guys were far too useless; even after I granted them the Devil Law, they were eventually killed by others."

"So, after they died, I simply devoured their souls... thinking back, it was a truly disgusting taste..."

The voice and tone were incredibly sexy and alluring, yet they spoke of heart-stopping words as the devil continued to sneer in Yu's ear. "Don't doubt it; such trash exists in this world, and there's more than one of them."

"So, keep training and make sure you survive in this world!"

After saying this.

The devil's voice gradually faded away.

It seemed to have fallen back into a deep slumber.

"I see..."

"It seems there were a few guys even unluckier than me before I came along..."

After listening to the devil's words, Yu stood in place and muttered to himself.

In his heart, he couldn't help but silently offer a moment of silence for those poor souls who had been devoured by the devil.

"But since that's the case..."

"Then I can't afford to slack off even more!"

Returning his gaze to the reality before him, as if stimulated by the devil's words, Yu's eyes became even more resolute.

"Three days from now is the Ninja Academy entrance ceremony."

"At the very least, I have to complete the other ninjutsu before then..."

Feeling his chakra gradually recovering to more than half.

Yu gritted his teeth, mobilizing all the chakra in his body to condense frantically in the palm of his right hand.

"The first three stages of training are already complete."

"I've used up enough chakra for today; this is the final stage! Success or failure hinges on this one attempt!"

Accompanied by Yu's highly focused gaze.

Blue chakra gathered continuously in the palm of Yu's right hand.

Countless violent chakra whirlwinds emerged, and a sphere radiating a pale blue light gradually took shape in Yu's hand.

That's right.

The technique Yu was about to cultivate next was none other than the signature jutsu of the Fourth Hokage, the Yellow Flash, Minato Namikaze—the Rasengan.

The original work had already explained the cultivation method and principles of the Rasengan quite clearly.

Over the past two months, in addition to developing his String-String Fruit abilities and training his taijutsu, Yu had successfully completed the first three stages of Rasengan training.

Therefore, today, Yu intended to master not only the Chidori but also the Rasengan, capturing the signature techniques of the two main protagonists, Sasuke and Naruto, in one fell swoop!

First and foremost, the Rasengan is a hand-seal-less jutsu.

It was perfectly suited for a ninja like Yu, who would eventually engage in high-speed combat.

It was a powerful A-rank jutsu developed by the Fourth Hokage, Minato Namikaze, inspired by the Tailed Beast Bomb.

Anyone who had watched Naruto would know that the impressions left by the Fourth Hokage, Minato Namikaze, were the Flying Thunder God and his "ball-spinning."

But in reality, the Fourth Hokage was not limited to just the Flying Thunder God and the Rasengan.

His chakra possessed three natures—lightning, wind, and fire—and he knew many mainstream ninjutsu, as well as the Toad Sage Art of Mount Myoboku.

However, Minato Namikaze's combat style was extremely fast; for him, forming hand seals was a waste of time, which was why he rarely used other ninjutsu.

Although Yu did not currently possess a space-time ninjutsu as broken as the Fourth Hokage's Flying Thunder God, the combat system he had mapped out for his future—whether it was taijutsu combined with the rapid-fire capabilities of the String-String Fruit, or the ability to fight using Demon fruit-powered human puppets—had already destined that most mainstream ninjutsu requiring hand seals would not suit him.

Therefore, Yu also wanted to try injecting his own chakra nature transformation into the hand-seal-less Rasengan to create a powerful, unique jutsu of his own.

However, until he reached the chakra level of a Jonin, Yu had no way to inject chakra nature transformation into the Rasengan.

"Success!"

Through Yu's unremitting efforts, a sphere of light, constantly emitting a blue chakra vortex, finally appeared in the palm of his right hand.

"Strange..."

Why do I get the feeling this Rasengan is different from the protagonist Naruto's?

Before he could even process the excitement in his heart, Yu stared at the successfully condensed Rasengan in his hand. He felt there was something different about it compared to the Rasengan of the protagonist, Naruto Uzumaki, from the original work, but he couldn't quite put his finger on it.

"I'll just have to test it and see."

With that thought in mind, Yu subconsciously threw the Rasengan in his hand.

Yes, he threw it.

Under Yu's watchful eyes, after the Rasengan was thrown, it emitted a slight whirlwind in mid-air before quickly vanishing into the air.

"Did it fail??"

Seeing the Rasengan he had thrown disappear halfway, Yu's eyes widened slightly, and he couldn't help but feel a bit dejected.

BOOM!!

But just at that moment, the entire ground beneath his feet seemed to tremble slightly.

Before Yu's incredulous gaze, the Rasengan that had clearly vanished reappeared.

It erupted with astonishing power, directly snapping the entire tree standing in the distance!
