Modified Rasengan, Demon Flash

"Speaking of which, between Chiba and Laxus, who is stronger?" Natsu suddenly looked at Chiba and asked expectantly.

Chiba said, "I am no match for him, at least not now."

"How does that compare to Erzamira?" Natsu pressed.

"Well..." Chiba shrugged, "I haven't fought him, so I don't know. But it shouldn't be too far off, right?"

He can barely beat an A-level opponent now, but against an A-level opponent like Elsa Mira, he seems to be a bit lacking.

The differences are very large in S-Class, and about the same in A-Class.

"I, I will defeat Erzamira and Laxus sooner or later, but before I defeat them, I must defeat you, Chiba!" Natsu suddenly pointed at him and declared war with a smile.

Chiba remained silent. With your insane strength in the later stages, plus your own background music, there's no way I could beat you.

The two chatted and laughed all the way, although Natsu did most of the talking while Chiba listened with a smile. Time flew by, and they soon arrived at the forest outside the town.

Led by Natsu, they arrived at a secluded and quiet place. There was a wooden cabin there, neither too big nor too small.

"This is where I live!" Natsu jumped to the doorway and laughed, "So? Chiba, are you living with me?"

Chiba smiled and shook his head, then clasped his hands together and gave a low shout.

"Wood Release! The Four-Pillar House Jutsu!"

The earth began to tremble, the ground cracked open instantly, and countless trees danced in the air. In no time, the trees transformed into a two-story building.

Natsu stared in disbelief, then his eyes lit up with extreme excitement.

"Wow, this is amazing! This... this... is it Ninjutsu?!"

Chiba smiled and nodded.

Natsu looked at him hopefully and said, "Chiba, I also want to learn Ninjutsu. Can you teach me?!"

Chiba shrugged. "Ninjutsu isn't released from magic, but from an energy called Chakra. Aren't you using Dragon Slayer Magic? There's no need to learn Ninjutsu."

Natsu looked puzzled. "But I never told Chiba that I used Dragon Slayer Magic! How did you know, Chiba?"

"Forehead..."

Chiba's mind raced, and he finally said, "Mira told me. She also said you'll definitely become an excellent Dragon Slayer!"

Natsu curled his lip. "That guy, he always looks down on me and always calls me a kid, yet he secretly says things like that to you."

Chiba chuckled awkwardly, then changed the subject, saying, "Should I build one for you too?"

"Me?" Natsu pointed to himself, hesitated for a moment, and then said, "Forget it, I don't think I can live in a house that big, and I spend most of my time at the guild. Running back and forth every day is a form of training!"

Chiba nodded, didn't insist, said goodbye to Natsu, and then went into the house he had built.

Lying in bed, Chiba suddenly remembered what had happened during the day, and her brows furrowed slightly.

"Still too weak..."

He sighed. He had thought his progress was decent, but the thought of being suppressed by Laxus during the day made him feel depressed.

However, in a magic guild like Fairy Tail, where monsters abound, if he doesn't grow fast enough, he might be surpassed by Natsu and his group in just a few years.

Putting them aside, Mira is already above him now.

He closed his eyes, his consciousness entering the Ninjutsu Chamber.

In terms of Ninjutsu, he is already quite proficient in C-Class such as Gale Palm and Phoenix Flower Fire, B-Class techniques such as Shadow Clone, Earth Dragon Bullet, Water Formation Wall, and Fire Dragon Flame Bullet, and even the advanced Phoenix Flower Claw Crimson Phoenix Flower Fire. If he wants to advance further in Ninjutsu, he needs to learn more powerful Ninjutsu.

He walked among the Ninjutsu Chamber, his gaze sweeping over the scrolls on the shelf, finally settling on a Ninjutsu whose Ninjutsu was different from the others.

He picked up the scroll and slowly unfurled it.

[Demon Flash]: A-Class Ninjutsu, modified by Feiyin from Ninjutsu A-Class Ninjutsu Rasengan. Its essence is to transform the spherical Rasengan into a needle-like shape. In this state, the Ninjutsu's penetrating power is unparalleled, and upon entering the target's interior, it can rotate and destroy it. Because the technique is extremely fast to activate, requiring no hand seals, and the attack is completed in an instant, its attack is as ghostly as a phantom and as fast as lightning, hence the name Ninjutsu Demon Flash.

Chiba was stunned for a moment.

Modified Rasengan?

Isn't the Rasengan already the ultimate Ninjutsu with its extreme form transformations? What the heck is this ghostly shadow?

"To be precise, Demon Flash is Ninjutsu I created based on the characteristics of Chidori and Rasengan." At that moment, Feiyin's voice rang out behind him.

Chiba turned around, only to hear the girl continue, "However, in terms of shape transformation, it's more like the Rasengan, because it's also a compression and rotation."

"It combines the destructive power of the Rasengan and the piercing power of the Chidori. Externally, it takes the form of a needle compressed to its limit and constantly spinning. Once it pierces its target, it will transform into the shape of the Rasengan according to the user's will, destroying the opponent from within."

"Penetrating power, destructive power, plus attribute compatibility and stealth. I think A-Class rating is somewhat unsuitable for this Ninjutsu," Feiyin said.

Chiba: "..." (His smile gradually turns manic)

"This is the Ninjutsu!" Chiba accepted the scroll, deciding it was the one.

Feiyin was speechless and said, "This Ninjutsu is considered one of the most difficult to master among A-Class Ninjutsu. Are you sure you can master it?"

"How will you know if you don't try?" Chiba said.

"Alright, alright, whatever. You don't have anything to do right now anyway," Feiyin said, shrugging.

For the next period of time, Chiba immersed himself in learning this A-Class Ninjutsu. In fact, the initial stages of learning this Ninjutsu were not much different from those of the Rasengan.

It is compressed and rotated, eventually forming a needle shape.

If the Rasengan is compressed and rotated around a point, then the Demon Flash is compressed and rotated around a needle.

It must be said that this Ninjutsu is even more difficult to master than the Rasengan.

However, correspondingly, its practicality is also more extensive than that of the Rasengan.

For example... a sneak attack...

It is so small and well-hidden that it is perfect for assassination.

His days were spent practicing Ninjutsu. Without the chases and other such troubles, his progress slowed down considerably, probably due to laziness.

More than two months later...

"Demon Flash!"

With a low shout, Chakra rapidly condensed in his palm, forming a light blue needle of moderate thickness, which spun in Chiba's hand.

"Bang!"

He slammed his palm into the giant rock, and the rock shattered into pieces instantly.

"Not yet..."

Chiba frowned and dispersed the Chakra in his palm.

As he expected, after the Demon Flash pierced the rock, the rock would explode directly instead of shattering into pieces like this.

The scroll says that after the Demon Flash enters the target, it instantly controls the Chakra to form a sphere and destroys it from within. But he can never quite grasp that exact moment.

Because it was too fast...

This Ninjutsu, which is incredibly fast from start to finish, is truly a great test of one's reflexes.
