Naruto: Learn the Substitution Jutsu and use it to create Star Platinum?

Minato was equally startled.

"Yes, one to the left, and one to the right."

Jiraiya stared wide-eyed at the swirling light above Minato's head.

0.o

"Then, where should I direct my chakra?"

"I don't know either..."

Lin Yi slapped his forehead.

Only Minato trusted Jiraiya so much.

"Watergate, it might be speed."

"speed?"

Minato looked up and asked a question in return.

"Yeah, I just thought of that too. If it's unstable, it might be a speed issue, like a spinning top."

Lin Yi nodded and made a whipping motion.

"When the spinning speed is not fast enough, the top will become unstable and wobble around, but as long as the speed is fast enough, the top will become stable."

Minato nodded, seemingly understanding but not quite.

In any case, this is at least much more reliable than what Jiraiya-sensei said.

He stretched out his hand, and chakra began to gather. Just as it was about to dissipate, Minato also gathered chakra in his other hand and struck the chakra ball.

It's stabilized!

He looked at the chakra energy ball spinning steadily in his hand.

Minato looked excited.

"Success!"

Subconsciously, he loosened his grip on his other hand, and the chakra ball in Minato's hand rapidly expanded.

"Flash!"

"Smash Varudo!"

Jiraiya's horrified expression remained on his face.

One second later.

Minato and Jiraiya looked at Lin Yi, who was lying on the ground beside them, and then at the newly appeared giant crater in the distance.

"Thanks to you, Lin Yi."

Jiraiya also thanked him, but his heart tightened.

What just happened?

He didn't react at all.

"No...it's okay."

Lin Yi popped a soldier's ration pill into his mouth and waved his hand.

"It's stable, but it can't be released normally, and we still need to use the other hand to maintain it."

Although Jiraiya is unreliable, as one of the Legendary Sannin, he still has basic discernment.

"At least things have stabilized." Minato wasn't disappointed.

Any progress is a good thing.

The three sat down again, and Jiraiya opened a bag of popsicles.

He pried it open and glanced at the water gate.

"Watergate, which side do you want?"

"I'm fine with either side..."

"Hey, popsicle." Jiraiya casually handed one to Minato, then glanced at Lin Yi sideways, "Kid, you don't have one. Buy your own if you want one."

How childish.

Lin Yi rolled his eyes.

But Minato suddenly froze on the spot.

"If one hand accelerates to maintain the speed, unilateral rotation is unstable... So what if both sides rotate simultaneously..."

Then, he stretched out his hand, and a bright ball of energy began to spin continuously.

Unlike before, the internal rotation has changed from one direction to two directions.

The two forces lashed at each other like whips, maintaining a steady pace while continuously accelerating.

"It's starting to take shape!"

Jiraiya exclaimed in delight.

What does this have to do with you...?

Lin Yi glanced at Jiraiya with droopy eyes.

"Then let's call it..."

Minato smiled as he gazed at the energy ball in his hand.

"The Nimbus Popsicle inspired Lin Yi's Jiraiya's Spinning Double-Style Pill!"

"What a...long name."

"Ah, it really is long and tedious."

Jiraiya lowered his head and nodded in agreement.

"Alright, now that the development of the new technique is basically complete, I'll prepare for a new mission. I just got back, and the old man isn't treating me like a human being..."

Jiraiya said goodbye to the two while complaining.

"You guys should go and rest too. We just finished a mission and developed a new ninjutsu."

"Okay, Old White Hair."

"Okay, Jiraiya-sensei."

After Jiraiya left, Lin Yi turned to look at Minato, who was eager to try.

"Let's not play today..."

"OK then."

Minato scratched his head but didn't press the matter further.

Looking at the eager expression on Minato's face, Lin Yi sighed helplessly.

It feels like you've just recruited a new, powerful hero in a game; it's impossible not to try them out immediately.

Forget it.

"Let's go then, let's fight over in the woods."

He was afraid that if they fought again at the third training ground, the Hokage would make them pay compensation.

"The one next to the Hatake clan?"

"Next to your house!"

Lin Yi replied irritably that he had no intention of tearing down the entire forest surrounding the Hatake family's residence.

After the two finished packing their belongings and were about to take a step, a rustling sound came from the woods outside the training ground.

Immediately afterwards, a striking red hair appeared.

"Kushina?!"

Minato exclaimed in surprise.

"Why are you here, Kushina? Are you alright?"

Lin Yi, being sensible, stepped back slightly and quietly watched the show.

"Um, it's... the Third Hokage said... that we can go out for a walk today and clear our heads."

Kushina raised her head and awkwardly made up a lie.

"So that's how it is. I was wondering why I didn't see any guards."

You're hopeless, Minato, really.

Lin Yi patted his head.

"Those things are unimportant!"

Kushina's expression turned serious, and then she suddenly bent over, her hair falling straight down like a red waterfall.

"Yes, I'm sorry, I shouldn't have said that to you..."

Minato was stunned for a moment, then lowered his head in shame.

"How can I blame you? It's my fault for not keeping our promise to cultivate together."

Lin Yi nodded, "That's more like it."

"However, the ninjutsu that I was willing to break my promise to you to complete was developed precisely for you!"

"Hey, is it for me?"

Kushina looked up in surprise and pointed to her nose.

“Yes! In previous missions, I witnessed the danger of the Tailed Beasts and understood what kind of existence you, Kushina, were enduring, so I developed this technique. At least, it can enhance some of your power.”

So that I can protect you.

Minato didn't finish the sentence, but Kushina had already thrown herself into his arms.

Lin Yi smiled like a father, nodded, and prepared to turn and leave.
