"It's done... This is it..."

"Is this the signature move, Chidori, of the copy ninja Kakashi?"

Gazing at the highly condensed and raging electrical current on his left hand, Yu could feel every cell in his body being stimulated by this powerful Lightning Release chakra.

Swish!!

As he spoke, Yu's figure turned into a streak of lightning, instantly disappearing from where he stood.

Boom!!

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

A large tree about ten meters away had been completely shattered by the incessantly chirping Chidori in his hand!

"It's really powerful..."

The wild electrical currents in his hand gradually dissipated.

Watching the immense destructive power caused by the Chidori in front of him, Yu couldn't help but be amazed.

However, he felt a bitter smile on his face when he realized that over half of his chakra had been consumed in an instant.

"But this chakra consumption isn't something an ordinary Genin can endure."

Although he had broken through to the Genin level in terms of chakra, and with the modifications from the String String Fruit, Yu's chakra capacity was nearly several times that of an ordinary Genin.

However, Chidori, a high-level Forbidden Jutsu of the Lightning Release, had still consumed more than half of his chakra in one shot.

It should be noted that even Sasuke Uchiha, who faced Gaara during the Chunin Exams in the original story, could only use Chidori twice a day.

"Tsk tsk tsk... Truly remarkable talent and determination..."

After seeing Yu's outstanding talent and astonishing determination, he could only hear the Devil exclaiming with amazement, "I'm starting to like you a bit..."

"Like me? Come on..."

"Didn't you say you wanted to devour my soul that day?"

Hearing the seductive and alluring words of the Devil in his ear, Yu's expression of bitter smiling grew more pronounced. He wasn't foolish enough to take the Devil's words completely seriously.

"Hehehe... Well, it depends on whether you can survive in this world."

Hearing Yu's words, the Devil burst into continuous laughter, "I might as well tell you the truth, you're not the first host to awaken me in this world."

"But those guys before were just too useless. Even though I gave them the Devil's Law, they were eventually killed by others."

"So, after their deaths, I just devoured their souls... Thinking back on it, that taste was truly nauseating..."

Despite the extremely seductive and provocative voice and tone, the Devil's words were terrifying, and Yu could only hear him chuckle in his ear, "Don't doubt it, there are indeed such worthless people in this world, and there is not just one of them."

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

After saying that, the Devil's voice gradually faded away.

Seemingly falling back into slumber.

"I see..."

"It seems that before me, there were a few unlucky guys..."

After hearing the Devil's words, Yu muttered to himself, standing still.

In his heart, he couldn't help but silently mourn for those brothers who had their souls devoured by the Devil.

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

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

Returning his gaze to the real world before him, it seemed that the Devil's words had spurred him on, as Yu's eyes became even more resolute.

"Three days from now is the ninja school's entrance ceremony."

"At least before that, I have to complete another ninja technique..."

Feeling that his chakra was gradually recovering most of its strength, Yu clenched his teeth and mobilized all of his chakra within him, crazily condensing it in the palm of his right hand.

"The training for the first three stages is already complete."

"Today's chakra consumption is about enough, so there's just one more stage left! Success or failure hinges on this!"

With his highly concentrated gaze, a blue chakra was continuously gathering in Yu's right palm.

Numerous violent chakra whirlwinds emerged, and a ball of light with a pale blue chakra radiance gradually appeared in Yu's hand.

That's right.

The next technique that Yu was going to practice was none other than the Rasengan, the unique ninjutsu of the Fourth Hokage, Minato Namikaze.

The original story explained the training methods and principles of the Rasengan very clearly.

In the past two months.

In addition to the development of his String String Fruit ability and the practice of Taijutsu, Yu had successfully completed the training for the first three stages of the Rasengan.

So today, not only was Yu going to learn the Chidori, but he also intended to master the Rasengan, claiming the signature ninjutsu of both Naruto Uzumaki and Sasuke Uchiha, the two main characters in the original story!

Firstly, the Rasengan was a ninjutsu without seals.

Very suitable for a ninja like Yu, who would engage in high-speed combat in the future.

It was an immensely powerful A-rank ninjutsu developed by the Fourth Hokage, Minato Namikaze, inspired by the chakra of the Tailed Beast, the Nine-Tails.

For those who have seen Naruto, the impression of the Fourth Hokage, Minato Namikaze, is the Flying Raijin and Rasengan.

But in fact, the Fourth Hokage was not limited to Flying Raijin and Rasengan.

His chakra had three attributes: lightning, wind, and fire, allowing him to use many mainstream ninjutsu, including the Toad Sage Art of Mount Myoboku.

However, Minato Namikaze's combat style was extremely fast, and hand seals were considered a waste of time for him, so he rarely used other ninjutsu.

Although Yu didn't have access to Minato Namikaze's Space-Time Ninjutsu, which could be described as overpowered, he had already planned his future combat system.

Whether it was the ability to quickly launch attacks with the String String Fruit or the puppet combat with the Devil Fruit, Yu was not suited for most mainstream ninjutsu in the ninja world, which required hand seals.

Therefore, Yu wanted to attempt injecting his own chakra nature change into the Rasengan, creating a powerful ninjutsu that would be unique to him. However, until he reached the chakra level of a Jonin, Yu wouldn't be able to infuse a chakra nature change into the Rasengan.

"Success!"

Under Yu's unrelenting efforts, a ball of light emitting a blue chakra whirlwind finally appeared in his right palm.

"That's strange..."

"Why do I always feel that this Rasengan is slightly different from the one used by the main character, Naruto?"

Without having time to savor the excitement in his heart, Yu looked at the Rasengan successfully condensed in his hand.

He always felt that there was something different about it compared to the Rasengan of the main character, Naruto Uzumaki, in the original story, but he couldn't quite put his finger on it.

"Let's try it out, and I'll find out."

With this thought in mind, Yu subconsciously threw the Rasengan he held in his hand.

Yes, he threw it.

As Yu's eyes watched, after he had thrown the Rasengan, something unexpected happened. The Rasengan that had disappeared midway through its flight actually reappeared.

It erupted with astonishing power and directly shattered the large tree in the distance!

"Failed?"

Seeing the Rasengan he had thrown disappearing midway, Yu's eyes widened slightly, and he couldn't help but feel a bit disheartened.

Boom!!

But just then.

The entire ground beneath his feet seemed to tremble violently.

In Yu's incredulous gaze, the Rasengan, which had clearly vanished, unexpectedly reappeared.

It burst forth with astonishing power, directly shattering the entire distant tree!
