Numero started formulating his plan, he decided, he should aim to be the Strongest! since he's here, he believed in more action and less dwelling on matters.
He stood up and looked through his memories, it was really an astonishing feeling to have memories of someone else in your mind, in a few minutes he knew the structure of konoha and where to find what he was looking for, he didn't hesitate and walked towards the forest where he will meet the future best taijustsu master, he firmly decided not to be influenced by his youth and just learn basic body strengthening and taijutsu from him.
Walking towards his destination, he heard some words "If i cannot do thousand push ups, i will do two thousand squats!" he knew who it was from the voice, slowly walking towards the voice, he saw lee doing push-ups "Hey lee, what are you doing?"
Lee was surprised from the stranger's call to him and slightly embarrassed from how loud he was shouting earlier he asked "Who are you? do we know each other?"
Numero thought for a bit and said "No, i don't remember us meeting, i was just taking a stroll and got curious, when i saw you, i remembered a guy who looked quite like you but quite older calling you lee, as you were walking together the other day anyways all that aside, he slowly walked towards him "Can i train for you a bit, also i want to meet your sen-"
"Lee!, Youth has arrived" Numero rolled his eyes feeling awkward before watching the figure walking towards them.
After a bit of explaining and using his previous knowledge, Gai agreed to train him and told him a diet plan and daily exercises, while asking him to come over every at a specific time everyday to train.
Numero thanked him and got back home, while sighing in relief he wasn't sold the youthful spring fountain yet, just thinking about it made his head hurt.....
He sat down cross-legged on his bed and slowly tried to control his breathing while feeling the chakra around him, subtly his sense aligned with the environment and in absolute silence, he started to feel the mysterious energy in his body, slowly trying to manipulate it, he noticed he it was extremely hard for him, his charka would gather easily but just as he'll try to move it, there will be a small disturbance and all his gathered charka would collapse and disperse.
"Hm, this must be due to kurama's charka" But he didn't have any way to interact with kuruma so he just kept trying and succeeded in moving it a few times, no matter how many times he failed he kept trying, he knew there must've been prodigies that did it correctly the first time but it didn't put him down as he knew the amount of charka he has and will have in the future would all be worth the trouble.
Finally, its been a week since Naruto kept at his life routine, he kept molding his chakra every single moment of life he wasn't training or eating, he kept himself awake for hours and barely slept, he kind of worked himself to death because that's his nature, extremely obsessive towards what he wants, and finally he learned it, now he could gather chakra at any part of his body, though it didn't do anything yet and he didn't understand it much, he knew he should try tree climbing, and as he was thinking about water walking, he thought "Since walking on water you need to keep adjusting your Chakra to changing waves and ripples, its quite similar to these disturbances in chakra that Kurama creates for me, i need to keep adjusting my chakra" and slowly he improved greatly in controlling his Chakra, knowing he has alot of chakra(not including kyuubi's) and if he's able to control it correctly, he'll be able to effectively perform most justsu's.
Next thing, he bought chakra paper, generally most people don't know what it is, and it is only sold in the ninja store, he noticed it, while strolling around the village after his training to look for food supplies Gai recommended him to take, he thought why not give it a try and got one, excited he came to one of the training grounds where he started tree climbing at, he poured chakra into the paper and saw...
