Xu Zuren in Hokage

"Ok."

Naruto stood up and repeated the previous actions, continuously transferring chakra to concentrate in his hands, and then compressing it desperately to increase the power. During this period, he kept controlling, trying to make the chakra ball grow steadily.

But soon he couldn't control it as before. At this time, Jin Feiyu stretched out his hand and covered Naruto's hand that was trying to rub the balls. He used his method to help Naruto control chakra, and then directed Chakra towards him. Inject a little bit of thought energy into it to facilitate your own control.

The nature of the thought energy is very mild, and it makes no sound when added to the chakra. There is no other reaction, except for the flash of lightning in the gradually formed Rasengan, which represents its existence.

The chakra in Naruto's hand quickly stabilized with the help of Jin Feiyu, forming a blue ball-shaped, constantly rotating chakra aggregate in his hand.

Jin Feiyu said to Naruto: "Experience it carefully, and then remember how you feel now."

Naruto closed his eyes and concentrated all his energy on his hands, sensing the movement of chakra with all his strength, and trying hard to remember his current state.

Thanks to Naruto's efforts, the Rasengan's condition was very stable.

Upon seeing this, Jin Feiyu let go and said, "Let's try it. I'm also very curious about its power."

Naruto aimed at a big tree in the distance, rushed over quickly, and imprinted the Rasengan on the tree. The compressed chakra instantly expanded and exploded, forming a spherical thunder and lightning area on the ground. The diffuse shock wave uprooted the trees and covered the soil. The branches flew, the destructive lightning completely destroyed the area, and the ground was also damaged by the powerful force, leaving a large crater.

Naruto jumped back in time and away from the affected area. He looked at his hands in confusion and said in disbelief: "I caused all of this."

Since Kakashi had no specific function when he taught him, the power of the Rasengan shocked Naruto.

Jin Feiyu walked over and found that the giant pit that appeared was similar to the one he had made before, and there were signs of damage caused by rotation.

Jin Feiyu couldn't help but compare in his mind. It seemed that the Rasenian aura had disadvantages and advantages compared with this Rasengan.

First of all, the power of the Rasengan is released in a concentrated manner, and the damage to a single target is definitely higher than that of the Nen aura. Moreover, it is compressed to the size of a fist and can be moved with any magic. If it is fast enough, it will make the enemy very uncomfortable.

The Nian Qi field is released quickly and is not compressed, but is deliberately spread out. It can have unexpected effects in close combat, and the damage lasts long.

Both have their own merits. I can't say who is more powerful. I can only say that it is suitable for various situations. But I don't know how to use Rasengan, so why do I think so much.

Naruto hugged Jin Feiyu excitedly and thanked: "Thanks to you, I was able to learn the Rasengan so quickly. Thank you so much. You really helped me a lot."

Jin Feiyu patted Naruto on the back and said: "It's nothing. The main reason for your success is your own efforts. I just helped you a little, which is not worth mentioning."

Naruto jumped off Jin Feiyu, thought for a while and then said: "By the way, you don't know how to use the Rasengan yet, so I can teach you."

"Is this okay?" Jin Feiyu hesitated.

Naruto said decisively: "There is nothing wrong with it. Ninjutsu is meant for people to use. The more people learn to communicate together, the more powerful they will become. Besides, this is what I will give to you after I learn it. It doesn't matter."

Jin Feiyu was convinced by Naruto and had no worries. He was not a hypocritical person, so he said, "Okay, I'll excuse you, Naruto-sensei."

To be honest, Jin Feiyu really wants to learn. After all, having many skills is not a burden. If you have one more skill, you will have one more choice when you are in trouble in the future.

"Don't say it's troublesome or not, it's too foreign, but I like the title teacher very much, haha." Naruto said.

Naruto is very happy to be able to help Jin Feiyu. Jin Feiyu has always been taking care of him. This time he finally has the opportunity to repay him. It is very stressful to be in debt all the time.

Since Naruto, who had previously learned the aura of the Rasensen, had been practicing, and the Rasengan and the aura of the Rasengan also had a lot in common, Jin Feiyu became familiar with it very quickly, and he successfully used the nen in his hands in a short time. It condensed into a spiral pill.

Looking at the Rasengan in Jin Feiyu's hand, Naruto smiled with satisfaction, as happy as if he had mastered it.

After Kakashi and Tatsuna came back, they found that Naruto and Tsu Feiyu were already at home. Kakashi was surprised and teased Naruto: "What's going on? Don't you usually practice hard until very late? I want you to come back." If you're still unwilling, it's probably because you've learned it, right?

Naruto smiled and said nothing, just stretched out his right hand, and quickly gathered chakra in his palm to form a Rasengan.

Kakashi was shocked. He never expected that the Rasengan, which the Fourth Hokage spent three years developing, only took three days to learn in Naruto's hands. Although the difficulty of development and learning is not the same. , but being able to master an A-level ninjutsu in three days is enough to explain the problem.

At this time, Naruto said to Jin Feiyu: "It's your turn."

Tsu Feiyu also stretched out his right hand and used the Rasengan, and the two just looked at Kakashi. Kakashi was stunned when he saw this scene, and he was a little doubtful.

Are all the young people today so fierce? I originally thought that Sasuke could master the Chidori in about a week, which is enough. I didn’t expect that it took Naruto three days to learn the Rasengan. What’s even more unexpected is that Tsu Feiyu was protecting Tazuna by himself yesterday, but today he learned the Rasengan after training with Naruto for a day. This is so unreasonable.

The two of them scattered the Rasengan in their hands, and Naruto laughed and said, "How about it, I'll just say it will scare Kakashi-sensei."

Kakashi calmed down and couldn't help but ask Jin Feiyu: "What's going on? Why did Naruto suddenly learn it? It doesn't have anything to do with you."

Kakashi had reason to be suspicious. Yesterday, Naruto worked hard for a whole day without making any progress, and there was no sign of success. Today, Naruto and Tsu Feiyu learned the Rasengan after practicing together for a day, which made him uncomfortable. No doubt.

Upon seeing this, Naruto took the initiative to tell the story again, and Kakashi realized that his judgment was correct, and it was indeed all related to Tsu Feiyu.

However, Kakashi also touched Naruto's hair and praised: "Although there is a reason for Tsu Feiyu's help, the fact that you can learn it so quickly is enough to show that you are very talented and a genius."

Naruto is used to being called a loser. Sometimes even he himself doubts whether he is stupid. But when he heard Kakashi-sensei call him a genius, he was so happy that he didn't know his last name. Still giggling.
