Dragon Ball, while crossing the heavens and the world

Haruno Sakura came to teach Rasengan, providing Naruto with an excellent opportunity to hide his true power.

Naruto immediately agreed to the training camp.

That afternoon, he arrived at training ground No. [-] on time and met up with Sasuke and Sakura.

"Hi, Sasuke, Sakura, good afternoon!" Naruto entered the training ground wearing an unchanging coat.

Sakura responded enthusiastically with a good afternoon, and Sasuke sat in the stands of the training ground, resting his chin on his hands and humming lightly.

Sakura pulled Sasuke up purely to let him come out for some air. The main purpose this time was to help Naruto, so Sasuke was left directly in the stands to watch the two of them practice.

Sakura has a bold personality. After saying hello, she immediately got down to business and took out a large box from behind.

Naruto took a look at the box. It was filled with balloons and water balloons, which seemed to be used for practicing Rasengan.

"Naruto, we will start practicing the Rasengan this afternoon. Before practicing, I will first demonstrate to you the power and various applications of this technique."

Haruno Sakura led Naruto to the wooden target used to practice throwing ninja tools.

"The Rasengan jutsu is said to be a ninjutsu created by the Fourth Hokage, Minato Namikaze, after getting inspiration from the tailed beast jade and spending three years creating it.

This technique can concentrate chakra on the hand, continuously flow in irregular directions, and compress it to form a non-attributed chakra ball as big as the palm of your hand to attack the opponent. "

As she spoke, Haruno Sakura spread her right palm, and as she gathered chakra on her palm, she saw a light blue chakra ball appear in her palm.

"Look, Naruto, this is the Rasengan..."

Sakura pressed the Rasengan onto the dummy with one palm, and the Rasengan's huge force immediately made a hole the size of a basketball in the back of the wooden dummy.

Naruto has yet to express his opinion on Sakura Rasengan.

Sasuke on the side sneered: "What? This is the ninjutsu you want to teach Naruto. This destructive power is too weak. It's not as good as my casual blow."

Sakura looked at Naruto and said, "Do you think so too?"

Naruto shook his head.

Sakura smiled and said: "Don't think this ninjutsu is weak, the power of the initial Rasengan is indeed not very good, and its destructive power is not even comparable to a powerful fireball jutsu.

But the potential of this ninjutsu is very strong. As long as you can complete the changes in the shape and nature of chakra, you can expand this ninjutsu into various tricks. "

After saying that, Sakura showed off: "Look, this is my Rasengan combined with Water Release."

Sakura opened her palms again, and a high-speed rotating water ball appeared in her palms.

"go with!"

Sakura threw the Water Rasengan more than twenty meters away, and saw the water ball spinning crazily in the sky. The strong centrifugal force threw the water droplets everywhere. The water droplets were like bullets, smashing the ground and the target into pieces. Hornet's nest.

"This is a water-release version of the Rasengan that I created using the centrifugal force of the Rasengan and its internal pressure. Once this power is thrown into the crowd, it will be a large-scale destructive weapon. It is much stronger than the initial version of the Rasengan just now. Bar!"

Naruto nodded: "Well, it is indeed very strong."

Sasuke still said disdainfully: "The power of this technique is about the same as Ruyulu Senbon. It is enough to deal with minions, but it is still useless against masters."

Sakura curled her lips and said: "The power of the Rasengan mainly depends on the amount of chakra. Of course, the power is not that amazing when I use it. If Naruto learns this ninjutsu and uses his abundant chakra to use the Rasengan, the power will be It must be far superior to A-level ninjutsu."

After saying that, Sakura turned to look at Naruto: "Okay, Naruto, let's start training now!"

"There are three stages in practicing Rasengan. The first step is to condense chakra in the palm of your hand..."

"Is that so?" Naruto gathered the chakra in his hand and asked Sakura.

"Well, good control. You passed the first step." Sakura was not surprised by Naruto's performance. He just gathered chakra in his hands, which any chuunin could basically do.

"The second stage requires some props practice." Sakura put a balloon filled with water in her hand.

"You are already able to release and gather chakra from your hands. At this stage, you need to continuously and steadily release chakra to make the water in the water ball move irregularly until the water ball explodes."

Naruto asked: "Why do you have to do irregular movements and rotate directly in one direction? Isn't it easier to control?"

After that, Naruto controlled the water flow in the water ball to flow rapidly clockwise, and the water ball burst in a short time.

Sakura was stunned and said: "What you said makes some sense, but the disordered movement of chakra inside the Rasengan should be the creator of this technique - the Fourth Hokage wanted to simulate the movement of electrons in atoms..."

While talking, Sakura thought of something.

"Well, you inspired me. The laws of nature should be beautiful and simple. We artificially make the macroscopic Rasengan move in disorder, but it causes the internal conflicting chakra energies to cancel each other out, weakening the power and making it difficult to control. amplitude increased.

The Fourth Hokage's original intention was wrong from the beginning. The Rasengan should not be designed to be disordered. Orderly movement is more powerful. "

In fact, the Rasengan is said to move in a disorderly manner, but from the traces left by the Rasengan on the tree trunk in the original work, it can be seen that the Rasengan rotates clockwise as a whole and has a direction of rotation.

The Fourth Generation was superfluous and made the inside of the Rasengan move disorderly, which actually reduced the power of this ninjutsu.

This leads to the fact that Ninjutsu, which has an A-level training difficulty, is actually not as powerful as the A-level Water Release Technique of the Great Waterfall and the Great Shark Bullet Technique.

Even the difficulty of this A-level ninjutsu lies in the chaotic movement of chakra.

Without the need for chaotic movement of chakra, wouldn't the practice be at least downgraded by one level?

At this moment, Sakura tried to control the chakra to rotate clockwise, forming a spiral pill, and then smashed it to the ground. The huge spiral force suddenly smashed a large pit with a diameter of two meters in the ground.

"The power has indeed improved. After straightening out the chakra movement inside the Rasengan, not only the power of the ninjutsu has increased a lot, but the chakra consumed has also been reduced a lot. At the beginning of the development of this ninjutsu of the fourth generation, the theory was Wrong!"

After Sakura changed the movement of the Rasengan to clockwise rotation, she became more comfortable controlling the Rasengan.

She forgot about her job of teaching Naruto and ran aside to study the Rasengan's variant ninjutsu.

She stretched the ball of the Rasengan into the shape of a drill, and added the change of water release, making its power even more terrifying.

Sakura held the Tengen Breakthrough Spiral Rhinestone in one hand and pressed it on the stand made of earth escape next to the training ground, which instantly destroyed the stand.

The rhinestone left Sakura's hand and continued to spin, like a water dragon, drilling in and out of the stands, destroying all the more than ten meters long stands.

With just a slight change, the power of the Rasengan, which could only smash the wooden target, suddenly increased to the level of S-level ninjutsu.

Sakura smiled, she had mastered the trick, and the Rasengan, which was originally difficult to control, was now easily controlled by her.

She flattened the endlessly rotating spiral, and the Rasengan changed from a ball into a high-speed rotating disk.

Sakura then performed the wind release change on the edge of the disk, and the Rasengan was immediately transformed into the Air Slash.

She expanded the disk in her hand to a diameter of ten meters, connected the center of the disk with a chakra line, and threw the disk away as if she were controlling a Fuma Shuriken or a yo-yo.

The giant disc just spun around in the forest at the edge of the training ground before being pulled back by Sakura.

Then I saw that all the trees in the forest were broken, the fractures were smooth and there was no stubble at all.

The disc controlled by chakra flew up and down, cutting the ground and masonry stands, just like a knife cutting tofu.

That kind of attack that was as fast as lightning and as sharp as a knife made Sasuke a little frightened.

He thought to himself that even if he controlled the metal elements to form a shield, he would probably be unable to withstand this terrifying cutting power.

As for relying on physical qualities or magnetic fields activated by current to resist, that is even more ridiculous.

His mere flesh and blood body could not stop the high-speed cutting of the chakra disk.

Magnetic field defense is only effective against metal-containing ninja throws. In addition to intercepting lightning attacks, other ninjutsu are difficult to defend against attacks that do not contain metal.
