From 4 years old until 8 we would be doing studies at home. The rules had changed since there was no wars going on. Academy acceptance age had changed from 6 to 8 years old. However most people are expected to know basic math and reading skills before being admitted. Usually the clans also have special skills they teach to their young ones such as combat stances or jutsu. Like for the Uchiha it's the interceptor fist and a basic fireball jutsu. Uzumaki however had seals.
"Today you'll be learning the basic chakra control exercises. Uzumaki are the owners of a chakra pool that is much larger than normal people. This has its pros and its cons." Kushina says sitting in front of us. "The pros are that we can use much more jutsu freely than other people and can use jutsu that usually drain others freely. The cons to this are we have problems with minor subtle jutsu such as Genjutsu. Any move that requires very little chakra to use you'll probably fail at."
"Now usually most kids start off with the leaf balancing exercise. We aren't going to be doing that. We are going to start with tree walking so follow me." She says getting up and heading over to a tree we had in the garden. "I want you to lay down on the ground and press your feet against the tree."
We do as she says I already know what's coming but this is much smarter than what Kakashi did just having kids run up trees and fall from them.
"Now focus your chakra to your feet and try to make your feet stick to the tree. If you put in too much chakra it will push you off the tree but to little and you won't stick." She says slowly walking up the tree.
Me and Karin get to work as she watches us. Our feet skid and scratch on the bark or bounce off randomly while we try to get it down how much power to use and how to control it.
"Everyday you will be doing chakra control excercises. When you master tree walking we will move on to water walking and when you master that we will go from there. You will also be doing taijutsu training with your new teacher who happens to be a rival of Kakashi." She says happily.
"Yosh!" A green blur jumps over the fence doing some fancy flips. "Kushina I have arrived to teach the young ones!" The man with a bowl cut shouts.
Might Guy number one taijutsu master of konoha.
"Hello Guy your a bit early they are still doing chakra control exercises so feel free to warm up." Kushina says not minding his loud entrance and excitement.
"Of course! If I can't atleast do 500 push-ups as a warmup before they are done I'll run around konoha ten times on my thumbs!" He shouts before starting to do push-ups like a mad man.
How youthful!
"Before you start training with Guy I'll be putting some Uzumaki training seals on both of you that your not allowed to deactivate unless it's an emergency." Kushina says pulling out a brush and special chakra ink.
She lifts up the back of my shirt before going to work. As soon as she finishes I feel like my body is extra sluggish like I'm moving through water.
"These are Uzumaki resistance and gravity training seals. They adjust and make you work harder all the time so you get stronger without any nasty side effects like weight training." She says making Guy who was listening face plant out of embarrassment since he does weight training.
"You okay Guy?" She asks him as she finishes Karin's seal.
"Uhhh yes I was just so excited about teaching that I slipped." He says with an awkward laugh.
"If you want a seal I can give you one too." She says with a sigh.
"That would be most youthful thank you." He says happily. After she finished giving him his seal that's when the hellish training began.
He was a monster. Every single exercise I've ever heard of and some I hadn't we were doing. Then we went to punching and kicking training dummies while he fixed our stances. Then we went to sparring were he fixed our stances more. Then we did running and more exercises.
This was until evening where the green beast finally left after giving Kushina our new diets to help our bodies out with the energy we were using.
This was how our hellish training was every single day for a year. We were children and there was pretty much fuck all to do here. No tv or music just studying and training. There was a bit of play time and recovery days. Which were so welcome. This continued until we were five years old and it changed a bit.
"I believe your ready for the uzumaki training course." Kushina says pulling out a scroll. "Your assignment is to learn this shadow clone jutsu which we be used for training. This jutsu requires quite a bit of chakra to use. However it's the perfect training tool as when you use a clone it remembers everything you did when it disperses. So you can have a clone do tree walking while your real body does exercises and you will gain that experience. Usually this is stressful on the mind but Uzumaki have a very good regenerative power that lets us heal extra quickly so we can take the strain unlike others."
That's when the hellish course increased in difficulty once we got 3 shadow clones up and running. One would do chakra control. One would do calligraphy. The last one would do shuriken practice. Not going to lie throwing shit at people to kill them sounds sweet. Our real body would be doing Guys training. We weren't allowed to make more than Three clones until our body adjusted to the strain of the extra load on our minds.
