Naruto : Minato back to the past

 An astonishing burst of chakra erupted from Minato's body. The chakra that exceeded his own endurance limit, although not like the previous Nine-Tails Chakra, formed a thin film in his body.

 But the strong chakra aura also overflowed, and strands of chakra gushed out from Minato's pores. His originally handsome face was stretched a little hideous at this moment.

 "What on earth is this kid going to do!"

 As a master of medical ninjutsu, Chiyo naturally saw that Minato had forcibly increased his chakra through drugs.

 In battle, it is extremely unwise to use this kind of drug, because the overly powerful force also brings an unimaginable load to the body.

 Swish!

 However, things went beyond Chiyo's expectations. After Minato's chakra surged, his speed increased to an even more terrifying level.

 Almost instantly, Minato's figure disappeared from her sight.

 At that moment, even she could not catch the whereabouts of this Konoha kid!

 In fact, Chiyo's expectations were correct under normal logic, but Minato had undergone two months of special training for this, and had gradually adapted to this forced improvement.

 What's more, his physical toughness was much higher than that of ordinary people after the transformation of the Nine-Tails Chakra.

 In terms of physical strength alone, among the five major ninja countries, there are probably only a few people from Raikage clan of the Lightning Country who can beat Minato now.

 When Minato's figure appeared again, he had already appeared at the edge of the battlefield between Sakumo and Suane. He raised his right hand, and a blue chakra light ball suddenly condensed in his palm.

 Rasengan!

 Minato and Sakumo exchanged glances, the latter nodded slightly, and then slashed at the steel puppet again.

 Inside the puppets, Sunae saw this, gritted her teeth, manipulated the puppet, and punched Sakumo.

 However, the speed of the steel puppet was reduced by nearly half due to Sakumo's attack. In Sakumo's eyes, the speed of the steel puppet was extremely slow.

 He actually jumped directly onto the arm of the puppet, and then ran up, aiming the chakra sword in his hand at the position of the puppet's head.

 "Don't worry about him, attack that kid!"

 Chiyo shouted again, her intuition told her that the blond kid in front of her would do something that surprised her again.

 When Sakumo and Sunae fought, Minato put both hands on the Rasengan, and gradually, on the blue chakra surface, a tiny breeze began to gather.

 Minato couldn't do it like Sakumo, and use his strongest method at will.

It takes time to prepare for the new jutsu.

 Sunae obeyed Chiyo's order and ignored Sakumo. The Iron giant raised one foot and wanted to crush Minato to death.

 Swish!

 Seeing this, Minato suddenly shot backwards and dodged the attack. The ground rumbled and snowflakes splashed.

 At this time, the expansion of Minato's body caused by the excessive chakra gradually calmed down.

 The "Rasengan" in his hand was wrapped with wisps of breeze, blowing the air.

 At this point, the nature of the Rasengan was almost halfway through, but Minato knew that the most critical step was the next step.

 "Help me stop it!"

 Minato shouted. At this moment, he had no way to spare his mind to resist Sunae's attack.

 Swish!

 Sakumo heard the words and immediately turned into a ray of light. At this time, the Iron giant's fist also blasted towards Minato.

 "Bang!"

 A loud noise rose. Sakumo held a chakra short sword, and there was still a residual light of lightning on the blade.

 He actually resisted the attack of the Iron giant

!

 If it was before, he would not dare to fight hard, but the speed of the steel puppet slowed down by nearly half, and the power it could exert was less than one-third of its peak.

 Even so, this force made Sakumo's palm tremble and crack directly, and blood flowed down along his fist that was tightly holding the handle of the sword.

 At this moment, Minato had no intention of watching this scene. His mind was focused on the chakra light ball in his hands.

 Blood began to appear in the whites of his eyes.

 Minato concentrated all his energy on one point to ensure the success rate of the ninjutsu.

 However, without using the Nine-Tails Chakra, he could only guarantee a 50% success rate at this time.

 "Buzz."

 After a few breaths, the wind attribute chakra condensed around the Rasengan reached a certain limit and underwent a qualitative change, and suddenly emitted a harsh buzzing sound.

 Unlike Sakumo's violent thunder sound before, this sound was not loud, but it had an extremely amazing frequency.

 The faster the frequency vibrates, the unique sound it produces is unbearable for human ears.

 Minato was the same at first, until later on, he slowly got used to it.

 However, for the several Sand Ninjas who came behind him, it did make them stunned for a moment.

 Minato had just left the battle circle of Sunae and Sakumo, and the ninjas of the Sand Ninja Village also took the opportunity to surround him.

 He just had no time to pay attention, but the effect caused by this vibration gave the Konoha Ninjas an opportunity to take advantage.

 Uchiha Yoruki, Suzuka and several Konoha Ninjas also appeared behind Minato.

 When looking at the "Rasengan" in Minato's hand, Uchiha Yoruki only felt a buzzing in his brain, and at the same time he was amazed that the former could actually condense such a terrible chakra.

 Under the external and internal factors, the magatama in his eyes rotated faster and faster, until it reached a certain limit, and then two more magatama were born from it.

 At this time, the "Rasengan" that appeared in Uchiha Yoruki's eyes was already in a different look.

 With the enhancement of his dojutsu power, he vaguely saw that at this moment, there were countless tiny wind thorns in the slowly condensing wind blades around the Rasengan.

 The number of wind thorns was simply incalculable. They were frantically agitated under the rotation of the wind blades!

 "What a terrible jutsu!"

 Uchiha Yoruki's pupils shrank. Even though he had just opened his second magatama Sharingan, he could not see through the ninjutsu in Minato's hand.

 "Buzz!"

 The buzzing sound became more and more deafening in just a few breaths, and the appearance of the Rasengan in Minato's hand had changed dramatically.

 they saw that around the azure chakra light ball, several wind blades formed by wind release chakra condensed, and compared to the length of only ten centimeters when he practiced before, the wind blades at this time were more than one meter long.

 Minato's face also turned a little pale, but at this time, he said silently in his heart.

 The originally exhausted body was rejuvenated at this time, and in a short moment, it returned to the peak!

 "Boom!"

 At this time, Sakumo once again hit Sunae hard, and the latter's strength had recovered. This time, even he flew backwards.

 However, when he saw the jutsu in Minato's hand, which was like a shuriken, he couldn't help but look ecstatic.

 Swish!

 The next moment, Minato's figure turned into yellow light again, and he rushed towards the steel puppet at an unreserved speed.

 At this time, the high-frequency vibration sound that made everyone on the battlefield deafened was extremely piercing.

 "Wind Release: Spiralling Gale Flash ( Resen Shippusen)!"
