Chapter 4: The Rasengan that I researched myself!

Under the rooftop

Kakashi was still eavesdropping on the conversation between these guys. When he heard about the battle between Naruto and Sasuke, he just frowned.

Obviously, Kakashi had no intention of stopping them.

In other words, they would not be stopped before they were in danger.

Kakashi could take this opportunity to observe the weaknesses and strengths of these two little guys. At least before Sakura grew up, Naruto and Sasuke should be the main fighting force of Team 7.

"Naruto, do you really want to fight Sasuke?"

Sakura looked at the two boys standing opposite each other and said, "Sasuke-kun has always been the number one in the Ninja School! And you have always been..."

"The last one, right?"

Naruto smiled, moved his fingers vigorously, and whispered: "Even if I'm the last one, I still have the heart to become the top student!"

While in Ninja School, he often took the initiative to challenge Sasuke. Now that he had mastered several ninjutsu, he also wanted to test his own strength.

Because no one of the same period was more versatile than Sasuke.

In addition to the basic techniques such as the clone technique learned in the ninja school, Naruto now had four new techniques, except for the relatively unfamiliar [Sealing Technique·Devouring]...

The remaining [Rasengan], [Wind Style: Rasenshuriken], and [Multiple Shadow Clone Technique] seemed to be familiar to him after using them countless times!

"I'm going to attack, Sasuke!"

Naruto shouted loudly and rushed straight forward!

A flying kick was aimed at Sasuke's shoulder, but he blocked it with one arm. Then Sasuke twisted his body to use the force and kicked Naruto in the abdomen!

The two figures intertwined in an instant!

As the fists and feet clashed, it seemed like real fire was ignited!

Only Sasuke knew that Naruto's current physical skills were obviously better than when he was in the ninja school!

Sasuke looked at Naruto's palm, his mind moved, and then he clasped three fingers down to restrain Naruto's palm!

Just as he was about to proceed to the next move, Naruto chuckled: "Ha, Sasuke, do you want to use my palm to help you make a seal?"

"Um?"

Sasuke was stunned for a moment, and then Naruto pulled his palm away!

He was still thinking in his mind why this move was exposed...

In the physical combat of ninjas, because the physical combat was too fast, most ninjas could not find time to form hand seals and perform spells, so many people invented strange ways of forming hand seals.

There is no doubt that taking advantage of the opportunity of physical combat and using the enemy's palm to complete a certain seal can undoubtedly save time and even catch the enemy off guard.

In addition to working hard to practice ninjutsu and shuriken, Sasuke would occasionally think of finding other shortcuts. For him, any opportunity to become stronger must not be missed!

He had just tried to learn the skill of [Borrowed Hand Seal], and now he could only use it for the Great Fireball Technique. He had originally intended to use the opportunity of fighting with Naruto to see if it would work, but he hadn't expected that Naruto would reveal his plan just as he was about to do it!

Perhaps, this trick wouldn't work?

"What a terrible method!"

Naruto flew forward and kicked, saying, "If I use the enemy's finger seals, many enemies probably won't be able to react if they don't realize it, right?"

"snort!"

Sasuke raised his arm to block Naruto's flying kick, and his brows could not help but frown. The heavy force almost knocked him to the ground!

Since the ninja school, every time he fought with Naruto, he could feel that this guy's strength was getting stronger and stronger!

Even though he was the most proud clan in Konoha, he could only rely on his own physical skills to resist Naruto's suppression of power...

This last guy is more difficult to deal with than before!

No, it should be said that he has really become stronger!

Sasuke put his arms together and blocked Naruto's punch!

He didn't even need to look to know that his arms must be red!

"In terms of physical skills, I'm still the last one, but I can occasionally perform amazing attacks, just like muscle memory..."

Sasuke glanced at Naruto who was still smiling confidently and continued to attack him. He suddenly felt something strange: "This guy didn't seem to be very diligent when he was in ninja school..."

Naruto scratched his yellow hair and said with a smile: "Ha, maybe I can't work as hard as the top student, but I won't fall too far behind..."

Indeed, in the entire ninja school, there is no student who works harder than Sasuke.

Perhaps because the family hatred weighed on his shoulders, Sasuke never gave up any opportunity to practice.

Naruto is different. He often skips cultural classes. Apart from the basic ninja physical skills, his chakra refining is not very good, and he can't even release those ordinary D-level ninjutsu...

Until that day, when he used the strange forbidden technique [Sealing Technique·Devouring] to devour all the red chakra in the sealed space, the Nine-Tailed Demon Fox became obedient, thus allowing Naruto to use ninjutsu skillfully.

Moreover, his physical skills also improved strangely, such as seizing the flaws in the enemy's attack to launch a counterattack. Although he had not experienced many battles, it seemed that he had mastered it now...

"I have to admit that I underestimated it in the past..."

Sasuke pinched his sore wrist and said in a deep voice: "But true accumulation is not achieved overnight!"

His palms suddenly came together, forming a seal!

The chakra in Sasuke's body instantly condensed in his chest, which swelled slightly. He pinched his fingers to his mouth and spurted out a stream of flames: "Fire Style: Great Fireball Technique!"

The flame expanded rapidly!

A huge fireball sprayed towards Naruto!

At the window of the Ninja School, Asuma, who was watching the fight between the two little guys, looked at the scene in surprise: "Are they worthy of being from the Uchiha clan? At this age, they can skillfully use C-level Fire Release Ninjutsu..."

"It's rare for a ninja school graduate to achieve this level!" Kurenai nodded seriously and whispered, "Maybe he's not as good as the brother who defected, but he's outstanding compared to most students..."

Asuma suddenly reacted and jumped out of the window to save people: "No, this level of technique will be dangerous..."

"Hey, hey! Calm down, Asuma!"

Kurenai pointed at Kakashi who had already climbed up the railing and said, "Don't worry, Kakashi has already gone up to rescue people..."

Kakashi, who had been eavesdropping on the rooftop, couldn't help but fly up to save Naruto when he heard Sasuke release the Great Fireball Technique...

After climbing onto the rooftop, Kakashi looked at the scene in front of him, and his mask was almost frightened off!

Naruto's smile remained unchanged, looking at the flames coming towards him, and stretched out his palm: "Sealing Technique: Devour!"

The chakra of the Great Fireball Technique was completely devoured by him!

The original scorching heat dissipated without a trace...

"Sasuke, you're too slow in forming hand seals!"

A Rasengan suddenly appeared in Naruto's palm, and then he rushed towards Sasuke with the Rasengan in his palm: "Rasengan!"

"etc!"

Kakashi looked at Naruto charging with the Rasengan in his hand, and seemed to see another shadow in him. He was slightly stunned!

Asuma in the distance shouted, "Hey, Kakashi, what are you doing! Stop those two brats!"

Kakashi reacted immediately, grabbed Naruto's arm, and pushed the Rasengan in his hand onto the parapet!

Bang!

The wall collapsed instantly!

Countless pieces of rubble fell to the ground with a crash!

Kakashi took a deep breath, looked at Naruto with sore eyes, rubbed his neck with his hand, and said pretending not to care: "Hey, Rasengan is not something you should learn at this age. When did you learn it..."

"I figured it out myself when I was in the practice field a few days ago..."

Naruto looked at Kakashi with some dissatisfaction: "Using this technique, I will definitely be able to defeat Sasuke!"

"snort!"

Sasuke couldn't help but be snorted when he heard this. When he saw the wall on the ground, he couldn't help but twitch his eyes: "..."

That technique called Rasengan is very powerful!

Perhaps due to the attack distance, there are still some flaws... But once it hits his body, it will definitely defeat him with one blow!

Sasuke looked up at Naruto. Has this last-place student in the school already possessed such strength without realizing it?

From this perspective, Naruto is much stronger than the woman named Sakura next to him, and she shouldn't be a drag on him in the team...

But in order to avoid being caught up by Naruto, he must also learn stronger techniques!

Just when Naruto was looking very proud, Kakashi's expression was a little broken: "Rasengan is the fourth Hokage's favorite ninjutsu, kid, there should be a limit to lying! In the entire ninja world, there are not many people who know that technique better than me..."

"Eh? The Fourth Hokage's technique?"

Naruto looked up in surprise. He pondered for a while, and the chakra gathered and spun in his palm again: "Then is this Wind Style Rasenshuriken also a technique of the Fourth Hokage? But this is indeed something I researched myself!"

As his chakra increased, wind-attribute chakra entered the Rasengan, and it gradually turned into a spinning shuriken!

"…This is…"

Kakashi's heart trembled, and the wind-attributed chakra mixed in the Rasengan directly changed the form of the technique, becoming a diamond-shaped shuriken!

This is more dangerous than the Rasengan!

No matter how you look at it, this technique doesn't seem like something a Genin should master! Especially since Naruto had just graduated from the Ninja School and was said to be the last in the school!

As a disciple of the founder of the Rasengan, Kakashi knew this technique quite well, but because his chakra was limited, he didn't dare to be so extravagant...

But Kakashi knew one thing very well, that even the Fourth Hokage had not been able to change the nature of the Rasengan!

"Become Hokage, surpass Hokage..."

Kakashi landed on Naruto's face and muttered to himself: "At this age, have you already surpassed the teacher in the Rasengan?"

"Oh, of course!"

Naruto interrupted Kakashi's thoughts and raised the Rasenshuriken in his hand: "Since Kakashi-sensei has appeared here, he obviously won't let the battle between me and Sasuke continue, right?"

"certainly…"

Kakashi took a deep breath and nodded at him...

If Naruto were to throw this Wind Style Rasenshuriken over again, the only remaining Uchiha clan member in the village would probably be extinct!
