Chapter 21 - Ninjutsu Training

After receiving endless torture from Gai's training, Naruto created 100 clones, 25 clones for finishing D-rank missions and 75 clones for studying at Konoha's library.

At the afternoon, he would be trained by his teacher, Kakashi. He already finished 5 D-rank missions and got another 50 points. Now he had 2 chances to extract the card. Moreover, he got a piece of information from the system, "After spending 1000 points, the system would be upgraded"

At training Ninja Field 3

Naruto was waiting there,

"Huh… Kakashi sensei always come late"

he had enough money after finishing ten missions. He bought a lot of balloons.

"Kage Bunshin no Jutsu"

Naruto created 1000 clones.

"Fill the balloons with water"

Naruto wanted to learn Rasengan, although the Scroll of seals didn't have the learning method, he remembered it from his memory watching Anime: Naruto.

The first stage was the rotation. "Rotation - the user learns to spin their chakra in multiple directions at once. To help in this regard, users may be given a water balloon so that they can mark their progress by the churning water; this step is complete once the users are able to burst the balloon with their chakra"

"Clones"

"Yes, boss"

"Put the water balloon on your hand. Then inject chakra to the balloon and spin it the until you are able to burst the balloon. Do you understand?"

"Yes, boss"

Naruto talked to Kurama. "Kurama sensei, guide me, please. This Jutsu, Rasengan was created by Minato Namikaze, which he based on the Tailed Beast Ball."

"Oh it's easy, use your imagination. Meanwhile, if you didn't have enough chakra, I will help you with chakra"

After a few minutes, one of the clones marked their progress by the churning water. Naruto released all of the clones, getting the experience. Then he created 1000 clones again and started to practice again. If he got the progress, he released all the clones. He repeated this process until he could burst the balloon with his chakra. If he used his chakra alone, he didn't have enough chakra to create 1000 clones, but now Kurama helped him. He didn't worry about it anymore.

"Easy. Now let's go to the next step. Kakashi Sensei hasn't arrived yet, I don't know why he's always late"

He repeated the training as the first step, but he used rubber balls now. the second step was Power. The user must increase the volume and density of chakra they output. To help in this regard, users may be given a rubber ball: there is no water inside to help them burst the exterior and the rubber shell is thicker than a balloon's.

Naruto created clones and dismissed the clones after he got to progress, and repeated these cycles until he could burst the rubber ball.

"Hahaha. Now the last step. It's too easy, now the third step" Containment - the user must combine the first two steps into a contained sphere. To help in this regard, users may be given a balloon to help them visualize the intended shape; if the balloon is popped or otherwise moves, mastery is not yet achieved.

Naruto repeated the cycles, he used his clones to help him form the Rasengan.

They were shocked, they looked at Rasengan in Naruto's hand. Moreover, he looked at the broken trees around the training

Yamato: "Rasengan? He could use Rasengan."

Kakashi: "Interesting"

Naruto looked at them "Uh, you are late, Kakashi Sensei, Yamato Taichou. Let's start our training"

Kakashi: "I had received your report from Hokage, and now you have mastered Rasengan, now we should teach you the basic Fire and earth ninjutsu. Look at this hand seal, and memorize it."

"Wait, sensei." Naruto created 1000 clones, meanwhile hidden within these clones, one of them opened his Sharingan, Kakashi and Yamato didn't know about this, meanwhile, the original Naruto started to save the Kakashi's Mangekyo Sharingan card and Yamato's Wood Release.

"Clones, observe Kakashi sensei carefully"

"Okay Boss"

Yamato frowned. "This is cheat…. Cheat"

"Fire Style: Fireball Jutsu"

Kakashi made a hand seal, kneaded chakra in his body and turned it into the fire, which then he expelled fire from his mouth

Kakashi "This the basic Fire Ninjutsu. If you already practiced the next step of an advanced form of Chakra control, you can create the bigger fireball, or shape it to the dragon form, or anything else, based on your imagination. Now you try it, Naruto"

Kurama "You heard what he said, kid. Imagination"

Naruto "Yes, Kurama sensei"

Naruto dismissed the clones and then he used his imagination.

"Hehe… Fire style: Fireball Jutsu"

Naruto created a fireball from his mouth, hitting the tree.

"I'm genius"

Yamato frowned "You are cheating… cheating"

"It's time for practicing an advanced form of chakra control, shape transformation. Shape transformation is an advanced form of chakra control that involves changing the form and movement of chakra, determining the size, range, and purpose of a technique., it's just using your imagination to create the bigger or the smaller form of Jutsu, by controlling your using of chakra"

"Oh, I understand" Naruto then created Rasengan, and made the Rasengan bigger until it reached 1 meter in diameter.

"Look, Kakashi sensei, it's easy"

After that, they practiced the next advanced form of chakra control, nature transformation. With the help of Yamato's Wood release and Kurama-Sensei guiding, he already mastered the nature transformation of wind, creating a new Jutsu "Rasen-Shuriken"

Naruto just smiled at them. Meanwhile, Kakashi and Yamato frowned. "This is cheating. You have 1000 clones and unlimited chakra. Moreover, you have the best teacher in your body, made from chakra, Kyuubi."

"So what should we teach to this kid?"
