*Bang* *Bang* *Bang*
You could hear some noises in the forest behind the Hatake house. It was actually the Hatake brothers training in tree climbing.
Kakashi landed on another tree as he dodged the kunai that was flying towards him. He was extremely fast to the point where his speed could rival an experienced genin.
A few minutes of training later Kakashi unceremoniously falls to the floor, he couldn't stand a second longer as he was completely exhausted. He had no energy or even chakra left.
"Urgh ... Eiji-ni ... please stop already, I'm dead tired." complained Kakashi. His brother was crazy! Throwing shuriken and kunai without an ounce of mercy. Just thinking about it made him shiver in fright.

-Time release: Flashback No jutsu-
"So Kashi-ni, did you understand what the theory is like?" Asked Eiji, although his brother was a genius, he had to confirm it.
"Yes"
"Then give me a quick recap" Eiji said, gesturing for him to continue.
"You ..." Was his brother really doubting his intellect? Sighing Kakashi surrendered and explained with a slight frown.
"Tree Climbing Practice is a training method primarily used to increase one's skill with chakra control. This training involves focusing a fixed amount of chakra to the bottom of your feet and using it to climb a tree without the usage of one's hands. If the chakra flow is too weak, the user will lose his position in the tree and fall. If it is too strong, the user will be pushed away from the tree, causing the tree to break around the contact point and the user will fall. "
"Excellent, as expected of my cute little brother, but there is something that those books at home don't say, do you know what it is?" Asked Eiji with a smile.
'Hmm? Something you don't teach in books?' Kakashi thought hard on the topic but couldn't find an answer. Defeated, again, he inquired his brother.
"What would that be?"
"It is not really a secret, but it is also not said. This practice, besides giving you some help in battle and controlling chakra, also serves to climb on rocks, as most rocks are smooth on your surface, yes...! you just need a little more control over your chakra, never forget that "explained Eiji patiently.
"You can use this as a reference as buildings, mountains,constructions of materials,and so on are extremely smooth."
"I understand, but how are we going to practice on them then? We don't have many building materials here in Konoha." Although Kakashi didn't leave much of the house, he had a general idea of Konoha throughout.
Thinking about what his brother said, Eiji sighed ... He hadn't thought about it, in his previous world he had so much of it that he thought it was completely normal.
"Well, one step at a time. First, try to climb the trees efficiently, This exercise should not take more than 1 hour, after that we will move to the next level" stopping a little, Eiji looked directly into his brother's eyes and warned.
"And I suggest you do it, otherwise you will regret it ... deeply." The end of his brother's sentence made him a really unpleasant.
****************
"Hey, Eiji-ni ... I made it!" Kakashi was upside down in a tree.
'Damn geniuses' murmured Eiji, he only managed to lie down for 30 measly minutes!
'I'm glad I got these weapons in advance, I'm a genius', Eiji nodded with satisfaction.
Seeing that his brother was pulling out a set of kunai that God knows where he got it from, Kakashi didn't have a good feeling.
"Hmmm, brother?" Kakashi hesitated a little to get his attention.
"What are you going to do with this?"
"Isn't it obvious? I'm going to train 3 things at the same time" Eiji's evil smile only grew every second.
Seeing that things were not very good, Kakashi still tried to question his older brother's motives,"And what are you going to train? Shurikenjutsu?" That was what he wanted to believe.
"Naaaaah, I'm going to practice my Taijutsu, My aim with the kunai and also climbing the tree"
'And your survival instinct' he added in his mind.
"But there are no targets here at home" warned Kakashi.
Eiji's smile grew and the fear of Kakashi too, the look his brother was giving him was not like "Shoot me, moving target"
"Well ... You are the target, if you don't want to be cut, Start running through the trees" Smiled Eiji as he took the kunai and aimed it on Kakashi.
Kakashi didn't hesitate at all and started running frantically among the trees, sometimes he slipped, but he managed to keep his balance.
"BASTARD!!!!!!!!"
"HAHAHAHAHAHAHAHA"
Curses and laughter echoed throughout the forest.
-Flashback no jutsu: KAI-
********************
"How do you feel, Kakashi?" Eiji didn't feel any remorse for what he did. It was necessary, and they were only a few years old. Kakashi will thank him in the future...maybe?
"Did you realize you bastard? You! You hit me a few times, if I wasn't fast enough you would have even killed me!" Kakashi shouted, his eyes burning with fury.
"Calm down, Almost all my kunai didn't even hit a tree, only in the end did I improve" Eiji defended himself as if he had been unfairly accused.
'Stopping to think ... How did he get so good? We were only doing this for a maximum of 2 hours, how did he improve so fast? ' Although his brother was treacherous, he had respect for him. Some people called him a genius. But it was actually his brother.
Eiji always learned everything faster than he did and taught him calmly as if he had been proficient for months, he even managed to create his own Taijutsu, Kakashi clenched his hands, he convinced himself that he would get better too.
Totally oblivious to what was going on in his brother's mind, Eiji went on to say, "I actually lied to you Kashi-ni, sorry"
Kakashi didn't understand and looked at his brother: "What do you mean?" He was perplexed, did Eiji deceive him?
"Yes, actually ... This training is done only for those who graduated from the ninja academy, that is, genins. Some take a few days, a week , others take two, While we learned it in just a few hours."
"This is something to be proud of," Eiji said with a little bit of embarrassment, but Kakashi didn't see as the scarf blocked half of his face, just like his mask.
"I see ..." Kakashi was irritated at first but soon calmed down, he understood why his brother did it and also ... He really didn't care, the more he learned the faster he would leave that Ninja academy, there wasn't much to learn from that place.
"Did you rest?"
"Because?" Eiji winked at Kakashi.
"It's time ... let's start the water walking training, the same way we trained just now, walking on the water is not much different from walking on the tree," he said while picking up some stray kunais.
"Is there a difference?"
'I thought it was all the same'
"Actually, yes. The difference is that the water is always in constant movement, so it is necessary to pay more attention to the flow of chakra that you release through your feet, the rest is similar to this one" explained Eiji.
"Is that it? Easy then" Kakashi casually commented.
'Is he getting convinced again? He deserves a beating' Eiji rolled his eyes at Kakashi, it wasn't the exercise that was easy, they themselves were just too good!
'Besides ... Kakashi doesn't have the Sharingan in his eye, so it doesn't limit his growth anymore' he thought distractedly as he took some small leaves.
"Why are you pulling leaves from the bush?" Asked Kakashi, curious about his brother's actions.
"Didn't you say that training was too easy? If other people knew what you said now, I'm sure you would be hated" Eiji replied to his convinced brother.
"What blame do I have if they are crap? They spend all day playing instead of training, they waste their time on futile things" grumbled Kakashi.
"And you think you're better? You can't even talk to a girl!" Eiji literally roasted Kakashi.
"You…!" Kakashi started, only to turn back, he did not deign to answer his brother, he never won in any way.
Without pestering Kakashi more, Eiji changed the subject: "These leaves here are for you to stick on your forehead while trying to balance yourself in the water, you will stick the leaf on your forehead with chakra, similar to climbing on the tree" Smiled Eiji as he handed over some leaves to his brother.
Kakashi didn't care about the difficulty of the training, he would instead be bothered if there was no training!
"Where are we going to train? Don't we have a lake here?" Kakashi inquired on the subject.
"Hot Springs!" Eiji exclaimed with great Enthusiasm.
