Synthesis Ninja system

After sending Might Guy and Sasuke Uchiha on their way, Shiro finally breathed a sigh of relief.

Now, it was time to learn the Rasengan!

"Hey, Pervy Sage! When are you going to teach me some jutsu? Next time there's a fight, I want to help out too!"

Jiraiya glanced at him, raising his right hand to gather chakra, but suddenly turned to Shiro.

"Shiro, why don't you go run an errand for me and buy some supplies?"

Shiro let out a wry smile. As expected, Jiraiya still didn't fully trust him.

But Shiro didn't mind. After all, in the future, Naruto Uzumaki would be throwing Rasengans around all the time, so he'd have plenty of chances to learn!

Taking the money, Shiro wasn't particularly excited about actually buying things, so he found a spot under a tree, closed his eyes, and rested.

About an hour later, Shiro bought a basket full of balloons as a token effort, then pocketed the rest of the money.

"Shiro, you're finally back. I've already used up all the balloons," Naruto complained.

Shiro handed Naruto a water-filled balloon without a word. Naruto took it eagerly, stood in a stance, and started focusing his chakra.

*Ding dong!* Jutsu recognized: Rasengan!

Shiro froze for a moment. He didn't expect to be able to recognize the jutsu just like that, and his previously lazy attitude suddenly turned into excitement.

*Ding dong!* Jutsu recognition: Rasengan (Progress 3%).

Shiro chuckled to himself. It wasn't going to be that easy, after all.

But if there's progress, it means more practice will lead to success!

"Naruto, are you using chakra to rotate and pop the balloon?"

Naruto was startled, hesitation written all over his face.

"The Pervy Sage said he could only teach this jutsu to me."

Shiro shrugged indifferently. "I get it, I'm just giving you some advice!"

He grabbed Naruto's other hand and placed it on the water balloon.

"If you want to pop the balloon with chakra alone, it would take months of training. But if you use your other hand to help, you can pop it instantly!"

Naruto, still doubtful, put his other hand on the balloon and quickly started rotating his chakra.

Due to the different directions of chakra flow from both hands, the water balloon began to shake violently.

*Pop!*

The balloon burst, splashing water all over Naruto's face.

Naruto jumped around in joy like a little kid.

*Ding dong!* Jutsu recognition: Rasengan (Progress 7%).

Jiraiya returned, and when he saw Naruto celebrating like a child, he couldn't help but smile too.

"What's got you so happy?"

Hearing Jiraiya's voice, Naruto eagerly ran over with a secretive grin.

"Let me show you my jutsu! Rasengan!"

Naruto used the same technique to make the water balloon spin rapidly, and in no time, it burst with a pop.

*Ding dong!* Jutsu recognition: Rasengan (Progress 15%).

"No way!"

Jiraiya quickly pulled out another water balloon and threw it to Naruto.

"Do it again, quickly!"

Naruto rubbed his nose with his finger and began channeling chakra again.

Within ten seconds, the balloon exploded once more!

*Ding dong!* Jutsu recognition: Rasengan (Progress 20%).

"Ah, I see now! You used two different chakra flows to burst the balloon! Naruto, you're a genius!"

Even though Jiraiya praised him, Naruto didn't seem as happy, awkwardly smiling as he admitted, "Actually, Shiro-kun taught me that."

Jiraiya frowned and turned to Shiro.

"Who are you really, to even know the principles behind the Rasengan?"

"I'll say it again, I have no ill intentions toward the Hidden Leaf Village!"

Shiro felt a little angry. He had helped the village numerous times, yet Jiraiya still didn't trust him.

"Pervy Sage, Shiro-kun is definitely not a problem! If it weren't for him, I would've been captured by those two guys!" Naruto quickly came to Shiro's defense.

After hesitating for a moment, Jiraiya smiled faintly.

"Naruto, why are you so worked up? I was just joking!" Jiraiya said, grabbing a balloon and holding it in his hand.

*Pop!*

The balloon burst in less than three seconds!

*Ding dong!* Jutsu recognition: Rasengan (Progress 40%).

Shiro was stunned. Naruto could only increase the Rasengan's progress by a few percentage points with each use, but Jiraiya's casual demonstration raised it by 20%!

The closer you are to mastering the Rasengan, the more progress you make with each attempt!

After finishing his demonstration, Jiraiya took out another balloon, tossing one to Naruto and another to Shiro.

"The second stage of Rasengan training is to pop this balloon with chakra. There's no water inside, so it's harder because you don't have any leverage. Relying on rotation alone to pop it is very difficult!"

Mid-sentence, Jiraiya turned to Shiro. "You're a genius. You probably figured out the first stage already. Now, let's begin!"

Naruto glanced at Shiro with excitement, and then, using the same method as before, he began channeling his chakra into the balloon.

Although the balloon twisted and turned, it showed no signs of popping, no matter how much he tried!

*Ding dong!* Task activated!

1. Complete the Rasengan using Shadow Clone Jutsu! Reward: Monster Strength!

2. Complete the Rasengan using two hands! Reward: Wind Release Chakra!

3. Complete the Rasengan using one hand! Reward: Chakra Shape Transformation!

Shiro instantly understood after looking at the rewards!

In this age of big data, even this system worked the same way.

Since he just started learning the Rasengan, the task was related to it.

"I choose option three!"

Although chakra shape transformation isn't the most powerful, it's the most practical.

With chakra shape transformation, you can modify jutsu infinitely! The more jutsu you know, the more useful it becomes!

As for completing the Rasengan, Shiro only needed to watch Naruto practice. Once the progress hit 100%, he could use the Rasengan immediately!

"Hey, Pervy Sage, can you show me again?"

Jiraiya shrugged nonchalantly and grabbed another balloon for another demonstration.

*Pop!*

*Ding dong!* Jutsu acquired: Rasengan (Progress 60%).

"Did you catch it that time?"

"Uh, can you show me one more time?"

"What's your deal?"

"If you do it again, I'll show you that forbidden jutsu Naruto's been practicing!"

Jiraiya was taken aback, and his nose started bleeding slightly.

"Alright, but this is the last time!"

*Ding dong!* Jutsu recognition: Rasengan (Progress 80%).

"Did you see it clearly? When are you going to show me that forbidden jutsu from Naruto?"

"How about one more demonstration?"

"Get lost!"
