Dragon Ball, simultaneously traversing countless worlds

Although he possesses even more powerful celestial magic, its origins are difficult to explain. Using it secretly is acceptable, but using it openly would easily attract covetousness.

Naruto could imagine that once he used Sage Mode, Danzo, the Konoha King, would be the one most eager to seize his Sage Mode.

Perhaps even the third generation will become envious and fight for the immortal techniques.

Naruto wasn't ready to overthrow Konoha yet, and he couldn't afford to turn against the higher-ups who coveted his territory.

Therefore, it would be best for him not to use his sage techniques openly, lest he clash with the higher-ups now and be branded a rogue ninja.

Chapter 341 Brother Ying’s version of Rasengan

Sakura Haruno's visit to Naruto's home to teach him the Rasengan provided Naruto with an excellent opportunity to conceal his true power.

Naruto readily agreed to the training camp.

That afternoon, he arrived at Training Ground No. 1 on time and met up with Sasuke and Sakura.

"Hi, Sasuke, Sakura, good afternoon!" Naruto, wearing his ever-present coat, entered the training ground.

Sakura responded enthusiastically with a "Good afternoon," while Sasuke, sitting on the training ground stands, rested his chin on his hands and gave a faint "Mmm."

Sakura only brought Sasuke along to let him get some fresh air. The main purpose this time was to help Naruto, so Sasuke was left on the stands to watch the two train.

Sakura has a straightforward personality. After greeting everyone, she immediately got to the point and brought out a large box from behind her.

Naruto glanced at the box; it was full of balloons and water balloons, apparently for practicing the Rasengan.

"Naruto, we'll start training the Rasengan this afternoon. Before we begin, I'll demonstrate the power and various applications of this technique to you."

Sakura Haruno led Naruto to the wooden dummy used for practicing ninja tool throwing.

"The Rasengan is said to have been created by the Fourth Hokage, Minato Namikaze, after three years of inspiration from the Tailed Beast Ball."

This technique allows you to concentrate chakra in your hand, causing it to flow and compress in irregular directions, forming a palm-sized, attribute-neutral chakra ball to attack your opponent.

As she spoke, Sakura Haruno opened her right palm, and as she gathered chakra in her hand, a pale blue chakra ball appeared in her palm.

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

Sakura slammed the Rasengan onto the dummy with one palm, and the immense force of the Rasengan instantly created a crater the size of a basketball on the back of the wooden dummy.

Naruto has not yet expressed his opinion on Sakura's Rasengan.

Sasuke, standing to the side, scoffed, "What? This is the ninjutsu you're going to teach Naruto? Its destructive power is too weak. It's not even as good as my casual strike."

Sakura looked at Naruto and asked, "Is that what you think too?"

Naruto shook his head.

Sakura laughed and said, "Don't think this ninjutsu is weak. The power of the initial Rasengan is indeed not very good. Its destructive power is not even comparable to a Great Fireball Technique."

However, this ninjutsu has great potential. As long as you can master the transformation of chakra form and nature, you can expand this ninjutsu into various variations.

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

Sakura opened her palm again, and a rapidly spinning ball of water appeared in her hand.

"go with!"

Sakura threw the Water Release: Rasengan more than twenty meters away. The water ball spun wildly in the sky, and the powerful centrifugal force flung the water droplets everywhere. The water droplets were like bullets, turning the ground and the target into a swarm of holes.

"This is a water-style Rasengan I created using the centrifugal force and internal pressure of the Rasengan. Once thrown into a crowd, it will be a wide-range weapon of destruction, much stronger than the original version of the Rasengan!"

Naruto nodded: "Yeah, she's really strong."

Sasuke remained dismissive, saying, "The power of this technique is about the same as Thousand Needles of Rain. It's enough to deal with minions, but it's still useless against experts."

Sakura pouted and said, "The power of the Rasengan mainly depends on the amount of chakra. Of course, the power of it isn't that amazing when I use it. If Naruto learns this ninjutsu, with his abundant chakra, the power of the Rasengan will definitely far exceed that of an A-rank ninjutsu."

After saying that, Sakura turned to Naruto and said, "Alright, Naruto, let's start training now!"

"Training the Rasengan involves three stages. The first step is to gather chakra in your palm..."

"Is that so?" Naruto asked Sakura, gathering his chakra haphazardly in his hand.

"Hmm, not bad control. You passed the first step." Sakura wasn't surprised by Naruto's performance; he was just gathering chakra in his hand, something any Chunin could do.

"For the second stage, we need some props to practice with." Sakura held a water-filled balloon in her hand.

"You can now release and gather chakra from your hands. This stage requires you to continuously and steadily release chakra, causing the water inside the water sphere to move erratically until the water sphere bursts."

Naruto asked, "Why make random movements? Wouldn't it be easier to control if we just rotated in one direction?"

After saying that, Naruto controlled the water in the water sphere to flow rapidly clockwise, and in no time the water sphere burst.

Sakura paused for a moment, then said, "What you said makes some sense, but the disordered movement of chakra inside the Rasengan is probably something the creator of this technique—the Fourth Hokage—wanted to simulate the movement of electrons in an atom..."

As they were talking, Sakura suddenly remembered something.

"Yes, you've inspired me. The laws of nature should be beautiful and simple. Our artificial manipulation of the macroscopic Rasengan into a disordered motion causes the conflicting chakra energies within to cancel each other out, weakening its power and greatly increasing the difficulty of control."

The Fourth Hokage's initial intention was flawed; the Rasengan shouldn't have been designed to be chaotic. Ordered movement actually makes it more powerful.

In fact, although the Rasengan is said to move randomly, the marks left on the tree trunks when it hits the tree in the original work show that the Rasengan rotates clockwise as a whole, and has a direction of rotation.

The Fourth Hokage's unnecessary addition of disordered movement within the Rasengan actually reduced its power.

This results in ninjutsu with A-rank training difficulty being less effective in actual combat than even A-rank techniques like Water Release: Great Waterfall Technique and Great Shark Bullet Technique.

Even the difficulty of this A-rank ninjutsu lies entirely in the disordered movement of chakra.

If the disordered movement of chakra is not needed, then cultivation would at least be reduced by one level.

At this moment, Sakura tried to control her chakra to rotate clockwise, forming a Rasengan, and then smashed it into the ground. Instantly, the huge spiral force smashed a crater with a diameter of two meters into the ground.

"The power has indeed increased. After straightening out the chakra movement inside the Rasengan, not only has the power of the ninjutsu increased significantly, but the chakra consumption has also decreased considerably. The Fourth Hokage's ninjutsu was flawed from the very beginning of its development!"

After Sakura changed the Rasengan's motion to a clockwise rotation, she was able to control it much more easily.

She forgot her job of teaching Naruto and went off to study a variant of the Rasengan.

She stretched the Rasengan sphere into the shape of a drill, added Water Release techniques, and made its power even more terrifying.

Sakura, holding the Tengen Toppa Gurren Lagann Spiral Drill in one hand, slammed it into the stands created with Earth Release next to the training ground, instantly collapsing them.

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

With just a slight modification, the Rasengan, which could originally only shatter wooden targets, suddenly became an S-rank ninjutsu.

Sakura smiled. She had mastered the trick, and the Rasengan, which was originally difficult to control, was now under her skillful control.

She flattened the endlessly spinning spiral, and the Rasengan transformed from a sphere into a high-speed rotating disc.

Sakura then used Wind Release techniques to change the edge of the disc, and the Rasengan was immediately transformed into a Spirit Disc Slash.

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

The giant disc only spun briefly in the forest at the edge of the training ground before Sakura pulled it back.

Then you see the trees in the forest snapped cleanly, the cuts smooth, without a single splinter.

The disc, controlled by chakra, tumbled up and down, cutting through the earth and the brick stands as easily as a knife slicing tofu.

The lightning-fast, knife-sharp attacks even made Sasuke a little scared.

He himself was terrified by the cutting force; even if he controlled the elemental metal to form a shield, he probably wouldn't be able to withstand it.

As for relying on physical attributes activated by electric current or magnetic field to resist it, that's just a joke.

His mere flesh and blood could not withstand the high-speed cutting of the chakra disc.

The magnetic field defense is only effective against ninja tools that contain metal. Against attacks that do not contain metal, it can only intercept lightning release techniques and is difficult to defend against other ninjutsu.

Chapter 342 Graduation Assessment Begins

Sakura Haruno has an amazing ability to control chakra. With this ability, she can easily change the shape of chakra, which is why she was able to modify the Rasengan into several versions with just a little guidance from Naruto.

If it were Sasuke or the Third Hokage, they wouldn't be able to do what Sakura Haruno does. Even if Sakura told them the tricks, they still wouldn't be able to do it without a long period of practice.

After Sakura Haruno had her fill of playing, she started teaching Naruto the new version of the Rasengan.

Naruto had already mastered the Rasengan, and after pretending to practice for an afternoon, he claimed that he had mastered the ninjutsu.

Having witnessed Naruto's rapid mastery of the Multiple Shadow Clone Technique, Sakura did not doubt Naruto's progress in learning the Rasengan.

She even felt that Naruto was a little slow in mastering the simple Rasengan.

"Just practice at home for the next few days. Once you've mastered the Rasengan, you'll have an attack method, and your graduation exam won't be too bad."

After Sakura taught Naruto the Rasengan, she left with Sasuke.

Naruto watched the two figures disappear into the distance, shrugged, and gave them a meaningful look.

So Sakura has already dealt with Sasuke? Aren't they afraid of gossip since they're always together?

Naruto returned home and continued to cultivate his Great Celestial Technique.

Two weeks later...

Naruto's true form arrived at the Ninja Academy.

The students gathered in the large classroom.

Iruka and Mizuki stood on the podium.

Iruka smiled warmly and said, "Students, today is an important day. It's the day to test your learning outcomes at the Ninja Academy."

Enough with the chit-chat. This graduation exam will be a group competition. The winners will pass the exam and receive the title of Genin.

Those who do not pass will continue their studies at the school.

After Iruka-sensei finished speaking, Mizuki chimed in, "Now, please come up and draw lots. Students who draw the same number will compete against each other in the same group..."

The students from the three classes, a total of 90, went up to the podium and drew lots from Teacher Shuimu.

Naruto casually picked up a fortune stick, looked down at it, and found it was the number fourteen.

"The fourteenth to go on stage? This order is not bad, neither too early nor too late."

Students who drew numbers looked at each other's numbers, searching for opponents with the same number.
