"This is a ninjutsu you created?"
Tsunade looked at Minato in amazement: "And more than two years ago? When you were five?"
Minato smiled shyly: "Just got lucky..."
"Incredible..."
Tsunade felt it was unbelievable.
Since mastering the five-attribute nature transformations, Minato had stopped training in the yard because the space wasn't enough for him to mess around, so Tsunade wasn't very clear about Minato's strength progress.
"But I see this jutsu doesn't include nature transformation, so it shouldn't be completed yet, right?" Tsunade looked at Minato.
"Two years ago, yes. But in these two years, I have successively integrated five types of chakra nature transformations into it, and developed five different forms."
As Minato spoke, he extended his right hand. Chakra gathered rapidly in his palm, eventually forming a blazing chakra ball. Spiral flames surrounded the chakra ball, and the center was dark red.
"Like this one, it's the Dimensional Inspiration Explosive Flame Spiral Pill (Dimensional Inspiration Great Flame Rasengan) with added Fire Release nature transformation!"
"I see, Great Flame Rasengan!"
Looking at the deadly chakra ball in front of her, Tsunade nodded in understanding.
Minato subconsciously corrected: "It's Dimensional..."
"Shut up, it's Great Flame Rasengan!"
Tsunade glared at Minato: "What about the attack effect?"
"Oh, it's ultra-high temperature explosion, accompanied by super strong explosive impact."
Minato answered honestly, then formed a Rasengan with water ripples in his other hand: "There is also the Water Release: Raging Wave Tsunami Vortex Spiral Water Cannon!"
Tsunade snapped her fingers: "Vortex Rasengan!"
Minato's tone carried a hint of negotiation: "Sensei, this is a ninjutsu I developed after all..."
Before Tsunade could say anything, Kushina gently tugged at the corner of Minato's clothes: "Minato, just listen to Sensei!"
Minato: "..."
"Hahahahaha~"
Hearing Kushina's words, Tsunade put her hands on her hips and laughed loudly: "Come on, tell me what the remaining ones are called?"
"Wind Release: Rasenshuriken!"
Minato dispelled the balls in his hands and formed a Rasenshuriken.
A violent buzzing sound rang out, and a strong gale swept quickly through the yard.
(Rasenshuriken can be thrown not only with Sage Mode, but only when the completion rate reaches 100% can it be thrown for long-range attacks. Naruto only perfected the Rasenshuriken through Sage Mode. In the original work, Naruto used it in non-Sage Mode more than once.)
"Strange? Why is this name so normal?"
Tsunade looked at the Rasengan shaped like a shuriken in Minato's hand, feeling surprised.
"Because it looks like a shuriken and can be thrown like a shuriken."
Minato smiled. He couldn't very well say that this was a ninjutsu created by his future son and copyright needed to be respected.
Dispelling the Rasenshuriken, two special Rasengans, one blue and one yellow, appeared in his hands. The blue one glowed with wisps of electric light, while the yellow one looked unpretentious.
"In addition, there is the Divine Concealment Sneak Raid Thousand Thunder Roar Burst Spiral Pill! Can be thrown and can enter an invisible state!"
"Lightning Release: Thunderstorm Rasengan!"
"Super Giant Power Overlord Impact Mountain-Shaking Spiral Cannon! Can also be launched, has super strong impact force, and can easily blow up a small hill!"
"..."
Hearing these names, Tsunade felt her temples throbbing: "Just call it... Earth Release: Mountain-Shaking Rasengan."
Minato fell silent, looking like he had lost his color.
"Mmh hahahaha!"
Seeing Minato like this, Tsunade laughed even more wildly. She felt that Minato looked inexplicably cute like this, making her want to bully him severely.
"Whatever the name is! More importantly! Minato! Can you teach me?"
Nawaki grabbed Minato's arm: "I have Water and Earth dual attribute chakra. Just teach me any one!"
Minato said faintly: "Just integrate chakra nature transformation into the Rasengan."
Nawaki fell silent.
So, how do you practice chakra nature transformation?
Kushina tugged at Minato's clothes again, with a hint of expectation in her eyes: "Minato, can I learn this ninjutsu?"
"Of course!"
Minato nodded. If he remembered correctly, this jutsu was originally developed for Kushina.
"Yay!"
Kushina cheered.
"By the way, how did you come up with the idea of creating this ninjutsu?" Tsunade asked curiously.
"Inspired by watching a washing machine work."
Finally someone asked.
Hearing Tsunade's question, Minato took out the rhetoric he had prepared long ago.
"Once the washing machine at home broke down. I found that if the water couldn't be spun out during the spin cycle, the washing machine would vibrate constantly under the action of centrifugal force, and even move."
"So that's it..."
Tsunade nodded. This reason really made sense: "I didn't expect that washing clothes could inspire you to create a ninjutsu."
"Washing machine..."
The corner of Nawaki's mouth twitched: "I've watched the washing machine wash clothes a lot too, why didn't I see any tricks?"
"Just... luck."
Minato smiled awkwardly. Compared to the inspiration from observing Tailed Beast Bombs in the original work, the washing machine reason was really a bit low-class, but he couldn't think of a more suitable reason.
"Then in the subsequent special training, can you teach us the training method for nature transformation?" Nawaki asked hurriedly.
Minato nodded: "Of course, but before that, you have to pass the trap assessment first."
"Still doing that?"
Nawaki wailed. Now he felt sick just seeing exploding tags.
Minato smiled. Only the training of avoiding traps was non-negotiable!
Same old saying: Only those who survive are fit to deal damage!
And because of the changes in the Land of Rain, the originally scheduled special training time was drastically shortened. For this reason, he specially sent clones to the training ground this morning to increase the difficulty of the trap mechanisms.
The traps he set up previously could at most be considered medium difficulty, which could be seen through at a glance by experienced ninjas.
But now the difficulty of the traps had increased, coupled with the density of the traps, even experienced Jonin would have to take two exploding tags.
In the days that followed, the four began high-intensity special training.
Nawaki and the other two continued the training of traversing the trap belt.
And Minato began the physical training he had been preparing for a long time.
Recently, his appetite and strength had been increasing rapidly. Minato felt that he should have reached his growth period, which was a good time to train his physique.
So he asked someone to forge a set of full-body weights and a steel ball with a diameter of one meter.
When the steel ball was hung by vines in front of the valley entrance, Kushina and the other two gathered around curiously.
Kushina asked curiously: "Minato, Minato, what is this?"
"Training equipment." Minato said.
"Training equipment? Hmm—"
Nawaki tilted his head: "Is this... a weight?"
"No."
Minato stepped forward slowly, then squatted in a horse stance, sank his Qi to his Dantian, and then slammed a punch onto the steel ball!
Clang——!!
Under the dumbfounded gaze of the three, the steel ball instantly made a loud noise and was actually sent flying by Minato's punch!
The huge steel ball broke the vines and was deeply embedded in the rock wall of the mountain.
"Gulp..."
Nawaki swallowed his saliva: "Is this... Sister's Monstrous Strength?"
Blood dripped from Minato's fist, but his tone was very calm: "No, this is pure strength without chakra!"
