From the night of genocide, marching towards the strongest.

Therefore, ordinary special training is no longer suitable for Team 7. Instead, based on the team's superb chakra control, a brand new ninjutsu is taught.

"This ninjutsu requires extremely high chakra control. Watch closely!"

With that, Kakashi opened his right palm, and visible streams of chakra gathered in his palm, compressed, and spun at high speed.

In the blink of an eye, the condensed and rotating chakra formed a light blue chakra ball in his palm, containing whistling lines and bringing up gusts of air!

Rasengan!

"This ninjutsu is actually a no-seal ninjutsu?"

Sakura was startled, stopped writing, and exclaimed in surprise. Then, she quickly realized what she had done and asked:

"Kakashi-sensei, is this technique the Fourth Hokage's Rasengan?"

"Rasengan? What kind of ninjutsu is that? Sakura, do you recognize this ninjutsu?" Naruto asked, looking completely bewildered.

“Of course!” Sakura nodded, quite pleased with herself, and explained in a seemingly serious manner, “I once heard Grandpa Kosuke say that the Fourth Hokage created a ninjutsu called Rasengan, which involves concentrating chakra in the hand and then rotating and compressing it!”

"A ninjutsu without hand seals, compressed and rotating, and Kakashi-sensei was the Fourth Hokage's disciple, so this ninjutsu must be the legendary Rasengan created by the Fourth Hokage!"

"I see." Naruto nodded, muttering to himself, "It doesn't sound that impressive."

The Konoha Dragon God technique he learned utilizes his body and wind-style chakra to spin at high speed, creating a tornado to attack his opponent. Moreover, it involves spinning his entire body, making it seem more difficult and powerful than the Rasengan made solely with his palm.

"Idiot!" Sakura gave Naruto a flick on the forehead and shouted, "Since it was created by the Fourth Hokage, of course it's powerful!"

I am the successor of the Fourth Hokage, and I will not allow anyone to say that the Fourth Hokage's ninjutsu is ineffective!

Seeing the two playfully bickering for a while, Kakashi had a bit of a headache and said calmly, "Sakura, you guessed right, this is the Rasengan created by my teacher, the Fourth Hokage!"

"This is a ninjutsu created by my teacher over three years. It concentrates chakra in the hand, flows it in irregular directions, and compresses it to form a chakra ball the size of a palm, which is then used to attack the opponent. Being hit by it will cause chakra disorder for a short period of time."

"Its key feature is that it requires no hand seals, yet it possesses immense power!"

As he spoke, Kakashi looked at Sakura and said with a smile in his eyes, "Sakura, you have learned my teacher's Body Flicker Technique. With your intelligence, you should be able to roughly guess what my teacher's fighting style is like."

Did Sakura also learn the Fourth Hokage's Body Flicker Technique?

Upon hearing Kakashi's words, Sasuke and Naruto were both startled and unconsciously looked at Sakura.

Sasuke had only thought that Sakura's Body Flicker Technique was impressive and unique, nothing more. In terms of speed, she was no match for him, let alone Naruto.

Furthermore, Sasuke hadn't even figured out Shisui Uchiha's Body Flicker Technique at the time, so he didn't have much interest in Sakura's Body Flicker Technique.

But now...

I want to learn!

"It should be fast!"

Seeing that Sasuke was also looking at her, Sakura secretly felt smug, but pretended to be calm and analyzed, "The Fourth Hokage is known as the 'Yellow Flash' and often wins battles by speed. He is known as the fastest ninja in the world. So the Fourth Hokage's fighting style is fast, and the Rasengan's characteristic of not needing hand seals and being almost instantaneous is a perfect match for the Fourth Hokage's fighting style!"

After Sakura realized that the Body Flicker Technique was created by the Fourth Hokage, she understood why the Fourth Hokage was hailed as the fastest ninja in the world, even though she herself was not known for her speed.

However, after carefully practicing this Body Flicker Technique, his speed increased by more than one level. Among his peers, apart from geniuses like Sasuke and taijutsu masters like Naruto, everyone else could only look up to him.

However, Sakura had heard from Grandpa Kosuke that this Body Flicker Technique was not the fastest Body Flicker Technique of the Fourth Hokage; he had another Body Flicker Technique that far surpassed this one.

However, Kosuke was vague about the name and effects of this ninjutsu, stating that very few people in the entire ninja world had the talent to learn the Body Flicker Technique, and Kosuke himself couldn't even understand it.

However, these things aroused Sakura's competitive spirit and curiosity.

Is it the technique of the Fourth Generation Lord?

I want to learn!

Sakura stared intently at the Rasengan in Kakashi's hand, making a silent resolution.

Not only the Rasengan, but also the fastest Body Flicker Technique, she wanted to learn it too!

Sakura's sudden, intense gaze left Kakashi somewhat bewildered. He was about to touch his nose, but halfway up his hand, he remembered he was still forming a Rasengan, so he silently lowered it.

Kakashi coughed lightly and looked at Naruto, who seemed to be listening to gibberish.

"Naruto, I remember your taijutsu technique is also a high-speed spinning move, right?"

I think his name was something like Konoha Dragon God?

Kakashi muttered to himself that he had often seen Naruto use this ninjutsu during the past month while Team 7 was on missions.

However, most of the time it ended in failure.

"Oh? Yes."

Naruto was taken aback, but quickly nodded.

“In that case, this ninjutsu is perfect for you!” Kakashi put on a smiling expression and said calmly, “I can tell that your taijutsu is an extremely advanced taijutsu, hmm… it should be nin-taijutsu.”

"Although this taijutsu is incredibly powerful, but..." Kakashi's tone shifted, and he said in a deep voice, "This taijutsu has a fatal flaw, which is the Dragon's Eye of the Tornado!"

Although Naruto's success rate with the Leaf Village Dragon God Technique was extremely low this month, he still managed to succeed a few times.

In the original timeline, it took Xiao Li nearly three years to figure out a way to counter this move after witnessing it.

Lee had only witnessed it once, while Kakashi had witnessed it no less than ten times. Coupled with the vast difference in their experience, Kakashi thought for a moment and realized the weakness of the Leaf Village Dragon God, but he just didn't have a way to break it yet.

"Huh!?" Naruto's eyes widened in surprise. "Even Kakashi-sensei noticed?"

When Teacher Chen taught him the Leaf Dragon God, he warned him that the Leaf Dragon God's weakness was the Dragon Eye.

What do you mean by "even I could see through it"?

Doesn't it seem normal to me?

Kakashi's lips twitched, and he said calmly, "Although both the Rasengan and your taijutsu involve high-speed rotation, your taijutsu is missing a step: condensation and compression!"

Seeing Naruto scratching his head, Kakashi smiled slightly.

"Once you learn the Rasengan and apply it to your ninjutsu techniques by compressing and condensing it, the extremely concentrated Dragon Eye will no longer be a weakness, but rather its most powerful fatal flaw!"

Naruto paused, scratched his head, and muttered, "I think Teacher Chen mentioned this to me..."

Teacher Chen realized the weakness of Konoha Dragon God, and his solution was to highly compress the Dragon Eye, thus strengthening the easily defeated Dragon Eye.

However, this also means that the caster will bear an enormous burden and face extreme danger, especially since it is a sharp wind-attribute chakra, and the Dragon's Eye is the location of the caster. If things go wrong, the caster will be reduced to ashes and to pieces.

Given Mr. Chen's advanced age, he was no longer able to do this, so he placed his hopes for improving Konoha's Dragon God on Naruto, who possessed an exceptionally strong physique.

He was also instructed that he should never attempt to improve the Leaf Dragon God without extensive experience.

The Rasengan is a highly compressed and continuously rotating technique, which, just as Kakashi-sensei said, is very suitable for him.

This can be considered as making up for his shortcomings in compressing and condensing chakra!

I want to learn!

While pondering, Naruto raised his head and shouted, "In that case, let's get started, Kakashi-sensei! I can't wait!"

Kakashi smiled slightly and withdrew the Rasengan from his hand: "Next, I'll explain the steps and key points of training the Rasengan... The first stage is to gather chakra in your palm... The third stage... ball practice..."

"In my estimation, with your talent, you should be able to learn this ninjutsu within seven days!"

Chapter 86 The Land of Waves Ends

However, as Kakashi predicted, Sasuke learned the Rasengan on the second day, and Sakura learned it on the third day, while Naruto, although in the original work he spent nearly forty days in total.

But now, with the tireless help of his nearly a thousand shadow clones, he has learned the Rasengan even faster than Sakura, and is eager to apply the principles of the Rasengan to the Konoha Dragon God.

This gave Kakashi a headache. He had planned to have some free time for the remaining seven days, but these students were learning too fast. By the third day, they had all mastered the Rasengan.

For other teachers, having three genius-level disciples is a good thing, but for Kakashi, it means he has fewer opportunities to slack off. His disciples' high talent also makes him, as their teacher, unsure of what to teach.

It's like he designed a month-long training plan, but it was completed in a week, and he still hasn't figured out what to do next.

Kakashi couldn't find anything to teach Team 7 right away, so he dismissed them under the pretext of exchanging ideas on their own.

"Kakashi, rest in peace." The members of Team 7 exchanged glances, and Sasuke spoke first.

"Since Kakashi-sensei wants us to exchange ideas on our own, then let's exchange ideas with each other. Come to think of it, we haven't really had any in-depth exchanges yet, so I'll go first."

"Sakura, I want to learn your Body Flicker Technique!"

Sasuke looked at Sakura and spoke directly.

"Why!?"

Naruto was taken aback, but immediately shouted, "I want to learn too!"

What followed was a series of polite concessions, entanglements, and disputes among the three.

What, Sasuke-kun? If you want to learn, then learn. Don't be shy.

This is what Sakura said.

What Sasuke needs to learn, I want to learn too!

This is what Naruto said.

Stop talking, just listen to me!

This is what Sasuke said.

In the end, Sasuke and Naruto exchanged Sakura's Body Flicker Technique for their own Shisui-ryu and Steel Fist Fluid Technique, respectively.

After resolving this matter, the three of them naturally shifted their conversation to the Rasengan they had just learned.

"Look."

Sakura held up the blue chakra ball in her hand and said to Naruto and Sasuke, "Although the Rasengan has the word 'spiky' in its name, it actually only rotates in one direction at high speed, not in both directions!"

"The true Rasengan should be like a whirlpool in the ocean. The external force of the whirlpool deflects to the left, so the internal force should deflect to the right. The entrance is negative and the exit is positive. If the exit is negative, the entrance is positive, just like positive and negative magnetic fields and the yin and yang fish of Tai Chi, generating a powerful attraction and pulling force!" (There is a concept of Tai Chi in Naruto.)

Naruto looked completely bewildered. He didn't understand anything about bias force, pulling force, or positive and negative electrodes, but at least he understood unidirectional and bidirectional rotation.

"Sakura, what's the difference between the one-way and two-way rotating Rasengan you mentioned?"

"Of course there's a difference!"

Sakura glanced at him calmly, her gaze indifferent and devoid of any discrimination, yet Naruto inexplicably sensed a feeling of contempt.

Disdain from top students.

"Naruto, you've seen a whirlpool before, right?"

After a pause, Sakura remembered that Naruto was a wind-attribute user and, fearing that Naruto might not understand, continued, "You should know what a hurricane or typhoon is, right?"
