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

Converging, condensing, rotating...

Within seconds, the two Jinchūriki had already condensed Tailed Beast Balls in their mouths that were several times larger than the ones Lin Yi had faced last time.

"Canteen Spicy Sauce!"

Platinum Star's imposing figure appeared.

"I'm not the same person I was last time."

Instead of retreating, Lin Yi advanced, instantly appearing atop the Five-Tails' head in a few blinks.

"Ora Ora Ora Ora Ora Ora ———"

Platinum Star's enormous iron fist pounded repeatedly on King Mu's head.

As fists rained down.

King Mu let out a wail, and his mouth actually slowly pressed down.

The Tailed Beast Ball was gradually compressed from a sphere into an oval shape under the pressure of the mouth.

On the other side, Jiraiya quickly bit his finger.

"Psychic art!"

As the white smoke dissipated, a gigantic toad, nearly as large as a tailed beast, appeared.

"Fire Release: Toad Oil Flame Bullet!"

The giant toad opened its mouth wide, and toad oil gushed out like ocean waves. Then Jiraiya stood on the toad's head, and flames adhered to the oil, rapidly expanding from a line of fire into a waterfall of flames.

Four-tailed Fox had no choice but to spread its arms wide.

Minato, on the other hand, gritted his teeth and clenched the kunai in his hand.

Lin Yi is right.

It really is... impossible to break through its defenses.

However, his ninjutsu, which he had been conceiving for over a year, was still making no progress... Chakra cannot be simply gathered to have sufficient destructive power.

Oh, right, the Tailed Beast Ball!

Minato's eyes lit up slightly.

In fact, Minato had long wanted to develop an instant ninjutsu that was extremely lethal and required no hand seals.

It had always been just a concept, but he gazed at the Tailed Beast Balls that were constantly spinning in the mouths of the two Tailed Beasts.

Inspiration kept popping into my head.

boom---

The loud explosion drew their attention.

King Mu's mouth was finally smashed shut, the Tailed Beast Ball exploded inside his mouth, and his massive body crashed to the ground.

But soon, the pale-faced Han used chakra to repair Mu Wang's form and immediately stood up again.

Damn it, here we go again.

Lin Yi's expression changed, and he ran outside.

The Tailed Beast Ball was barely stable; before it could even open his mouth, it had already condensed at the edge of his mouth.

If he dares to fight, the aftermath will be enough to make him suffer.

The four tailed beasts on one side slowly opened their arms, revealing the Tailed Beast Balls that had already condensed to overflowing.

"Minato, let's go!"

Jiraiya slapped the water gate.

Minato immediately nodded, pulled Jiraiya along, and appeared beside Lin Yi. Then, he put his other hand on Lin Yi's shoulder and instantly left the place.

Boom boom boom boom boom boom boom boom—

Dozens of miles away, Lin Yi and his two companions gazed at the mushroom cloud rising in the distance.

"Is this... the power of the Tailed Beasts?"

Minato's face was somewhat pale.

The one with the strongest power still resides within Kushina's body.

"Teacher, do we want more?"

Minato turned to ask Jiraiya.

Jiraiya waved his hand.

"That's enough. They should have nothing to do with Konoha, otherwise we wouldn't have found them here. If we provoke them further, it would be us provoking them."

This time, the two of them had basically finished gathering intelligence, and the mission could be considered complete.

Although we still don't know why the two Jinchūriki are always out there having fun, as long as they don't go to the Land of Fire, Konoha would be happy for them to run around.

After all, it was only an investigation into two Jinchūriki.

But that didn't actually make them fight the Jinchūriki to the death.

The return journey was naturally less rushed.

"Teacher, I have gained further inspiration regarding that ninjutsu."

"Oh, really?"

Jiraiya responded while licking the popsicle he had just bought in the Land of Grass.

"Ninjutsu? What ninjutsu?"

Lin Yi, licking a strawberry-flavored cigarette, walked to the water gate, put his hand on the other person's shoulder, pulled him over, and asked.

"Hmm... it's an offensive ninjutsu. Once I develop it, Lin Yi, you'll definitely see it."

Judging from your tone, I must be the first person to face it.

Lin Yi's lips twitched slightly.

Chapter 29 The Development of a New Ninjutsu by Straight Man Minato

"Old man, this is the mission report."

Jiraiya picked at his earwax while pulling a scroll from his pocket and tossing it to Hiruzen Sarutobi.

"You're a teacher now, yet you're still so immature."

Hiruzen Sarutobi put down his pipe, shook his head with a wry smile.

"There are no harmful actions or tendencies toward Konoha for the time being."

Hiruzen Sarutobi unfurled the scroll and quickly noticed Jiraiya's summary at the end.

"Yeah, it feels like they're just hanging out outside."

Minato scratched his gleaming blond hair, a look of embarrassment on his face.

Actually, when it comes to tracking, those two Jinchūriki didn't really hide at all; they were either running here or wandering around there all day...

Thinking of this, Minato secretly glanced at his teacher, Jiraiya.

It feels a bit like it...

"Minato, what are you looking at, kid?"

Jiraiya's voice, feigning composure, rang out.

"No, it's nothing, Jiraiya-sensei."

"Alright! Then I'll leave it to you." The Third Hokage replied to the three with a smile as he took out the reward and handed it to Jiraiya.

Although he still had some concerns, he didn't bother getting involved as long as it posed no threat to Konoha.

……

A quiet place in Konoha.

A tall tower stands alone, silently guarded by masked members of the underworld.

Even under the bright sunshine, Kushina inside the house still felt a sense of oppression.

Looking out the window, I finally saw the figure I had been longing for.

"Watergate!"

She couldn't wait any longer and burst through the door.

"Jinchūriki, calm down."

Two ANBU members wearing cloaks and masks instantly stood in front of Kushina.

Her red hair fluttered in the wind, and her immense aura even made the Dark Guard feel a little apprehensive.

"Didn't I tell you that I'm going to train in sealing techniques with Minato today?!"

After saying that, he shoved the two people in front of him aside and ran outside without looking back.

She grabbed the man in front of her.

"Wow, as expected of Minato! You timed the mission so perfectly. Let's continue practicing the sealing technique. By the way, how do you think your brain works? Many Uzumaki clan members take a long time to learn, but you mastered it in no time..."

Minato smiled as he watched the chattering red-haired woman before him.

But the thought of the tailed beast inside her body dimmed her expression slightly.

"Alright! Let's continue our training then! I'll be very strict, you know."

Kushina stomped her foot, pointed her finger to the sky, and was full of energy, completely different from the person who had been eagerly waiting before.

"I'm sorry, Kushina, today... I'm going somewhere else to train in new ninjutsu."

"…What?"

Kushina's smile froze on her face, but she quickly forced a smile again. "It's okay. If you don't want to learn sealing techniques, I can learn other ninjutsu with you."

"Feel sorry…"

"Then, where are you going to train? Again with that Uchiha Lin Yi, right? You clearly promised me!"
