"Do it all over again."

Twelve-year-old Kakashi gritted his teeth, and even though his hands were already shaking, he half-crouched down without saying a word, repeating the movement again.

The boy's hands were covered in scars, which made the simple act of gathering chakras on his hands very difficult.

The man in red in front of him looked at him indifferently and tried three times before he succeeded in turning Chakra's "nature change" into a thunder attribute, and the noisy sound of dazzling white electricity was like a birdsong.

It was late autumn, and the wind was blowing with a chill, and the whole forest was rattling.

"Hmph."

When he started to sprint, Kakashi snorted, using the thunder attribute chakra to activate his body, bringing higher speed, but also putting a greater burden on his body, if it weren't for the physical intensification technique called "Internal Force" that greatly strengthened his physical fitness, after so many times, he would have fallen long ago.

This Muji ninjutsu was born from the idea of the Spiral Pill, but there are many differences.

The spiral pill is a chakra "morphological change" technique, and the pure chakra high-speed movement only brings "physical" damage such as impact and friction.

In other words, it's just a miniature energy mass.

Kakashi was inspired by the core ideas of Muji Ninjutsu, but completely put aside the shackles of Spiral Pill and geniusly redeveloped another system of Muji Ninjutsu.

Abandon the mudra and start with the most basic nature change of the chakra, and attack the enemy with the thunderbolt of thunder and lightning in hand.

From this point of view, Makoto's Flame series is plagiarized from Kakashi's thinking.

However, in this world, the sequence of the two techniques is reversed, and it is only Makoto who guides Kakashi in developing a new technique.

The thunder light in the white-haired boy's hand cut through the sprinting ground like a sharp blade, and Makoto Uchiha watched silently, dodging to the left as he rushed in front of him and raised his hand to stab himself.

Kakashi tried his best to correct his stance, and apparently learned something after repeated it many times - he adjusted his pace as he sprinted, turning into small steps when he approached his target, especially when attacking, his left foot was not solid, and his right foot was slightly raised, ready to change the direction of his attack at any time.

However, this effort was tripped by Cheng gently stretching his legs, and it suddenly came to naught.

It's easy to imagine the consequences of an unstable center of gravity, Kakashi pounced on a hungry dog, lost his balance, maybe because of too much physical exertion, and his action of stretching out his palm to adjust his posture in mid-air actually failed.

Boom, the young man threw himself on the ground, rubbing the fallen leaves on the ground all the way, and slid out a long way.

The ground centered on Makoto was covered with marks, sharp lines that Kakashi had cut through the ground when he sprinted, and dirt ravines that Kakashi had left behind when he was as embarrassed as he was now.

"Hmm!"

Kakashi, who was lying on the ground, slapped the ground fiercely, splashing a pile of residual leaves, which was a rare emotional exposure for the teenager.

"Makoto, let's rest for a while." Kushina next to her couldn't stand it anymore, she looked at Kakashi who was still lying on the ground with some concern, and said to Makoto.

The three members of the Cheng class and the remaining Lin and Obito of the Water Gate class are all receiving the guidance of the Water Gate, while Kushina, who is usually very good to the students of the Water Gate, is relieved of the so-called "special training" of Makoto and specially comes to see Kakashi.

As things stand, her fears were justified.

"Again."

Turning a blind eye to Kakashi's embarrassment, Makoto said calmly, unmoved.

Kakashi rolled over and sat up, the expression under the mask unclear, but the sound of rapid breathing was clearly audible in the forest breeze.

"That's enough, Makoto." Kushina was not a weak woman, she approached, with a little undoubtedness, and said to Makoto.

"Reduce the amount of chakra you gather in your hands, this non-combat exercise, you can still do it at least 5 times."

Makoto ignored the spicy red-haired woman, and just said to Kakashi:

"After 5 times, I can't practice with chakra, so I use kunai instead."

"I have to wonder if the villagers have misunderstood what kind of so-called 'genius' you are complimented on."

Kakashi's eyes looked at Makoto, and only in the face of a very small number of people did he show this angry look, but Makoto looked at him defiantly and calmly, and his mouth was not forgiving at all:

"In that case, I'll let you remember this feeling with your body."

Knife skills are not only fast, accurate and ruthless, some postures and skills that have been tempered thousands of times, are the experience and instincts honed by a swordsman between life and death, especially if there is no room for such a moment, thinking is useless, this kind of skills and experience is extremely precious and important.

Yes, in Makoto's opinion, this new thunder attribute Wuji technique is not a ninjutsu, but a kind of "knife technique", and the activation of chakra to stimulate the body and condense the thunder light in the hand to destroy the enemy are just an appearance.

In the original work, when Naruto begged him to pass on this technique to himself, Kakashi said that the reason why he didn't teach Naruto was because this technique required the writing of the wheel eye, otherwise it would be difficult to control the super high speed when performing the technique, and it would be easy to hurt himself.

Is this really the case? Just three years after Kakashi said this, Naruto pressed the same type of "Ichikon" as this technique, and even surpassed the speed, on the chest of the third generation of Thunderkage, without writing the wheel eye.

Blaming Kakashi's inability to master this high-speed ninjutsu on the so-called Sharingan, Makoto can't admit it.

In particular, Kakashi's father, called "Konoha White Fang".

If there is one person in this world who can reproduce the sword technique of White Fang, then this person must be Makoto Uchiha.

Makoto's eyes were as red as blood, and the pale-haired figure was reflected in the magata, and the light in the figure's hand was as cold as snow:

"When to practice until you can't stand up on your stomach, when to stop.

"When you really master this technique, when will I give you back this short knife.

"Now you're only going to put it to shame."

Kakashi leaned down again, his left hand holding the wrist of his right hand, and the sound of squeaking electricity sounded in the jungle for an unknown number of times.

His white eyes were lit up and down by the thunder, but they never blinked. He heard the faint voice of the man in front of him, who had been the only one his father regarded as a disciple.

"Don't look at the enemy with your eyes, use the knife in your hand.

"Don't let me call you a waste, son of White Fang, can't you control the knife in your hand-"

"—what a joke!"

The thunder shimmered and wrapped around the palm of the hand that pierced the enemy's chest.

The Blood Mist Ninja's lizard-like eyes were fixed on Kakashi's close face, and his vaunted short-range reflexes didn't work, and when Kakashi rushed in a straight line, his long knife didn't even touch the corners of Kakashi's clothes.

In a cacophony of sounds like countless birdsong, Kakashi muttered to himself, but Kiristin didn't hear it.

He had seen the edge of the White Fang, so when he was hit by the Narakumi technique, he saw the phantom of Hachiki Shuo Shigeru behind the White Fang's short knife.

"What kind of trick is this?" He asked in a weak voice, gulps of blood spilling from the bandages on his face.

Kakashi pulled his hand from his body, glanced at him, and whispered back:

"Chidori."

"Good knife ......"

Kiristin laughed miserably with the last of his strength, but perhaps before he could finish it all, he was already dead.
