As soon as Haruto reached back to his desk, he exhaled a sigh of relief.
'Thank god he didn't need to operate on me… who knows what he could've done otherwise.'
Haruto sat at his desk and looked at the computers that were training the model and pulled out the scroll he'd just been given.
"Yang Body Enhancement Bath."
"Herbs freshly picked… ground into a salve and mixed with boiling water… performing a chakra absorption jutsu to absorb yang energy from the solution to strengthen the body…"
Haruto studied the scroll to see if he could understand any of it, but found it quite incomprehensible. All he could understand was the basics, that he had to sink himself in a medicinal bath and perform a jutsu to absorb the nutrients from the solution to improve his body's foundation.
'Hiruko said that Tsunade made this… Tsunade really has all sorts of clever jutsu related to the body… her Creation Rebirth jutsu, or her transformation jutsu that physically transforms her body…'
'It should be safe for me to use then…'
'But just in case I'll wait until I give Kakashi the scroll and ask him if it's safe for me to use.'
'It'll take another week until we meet but I guess I have to wait that long for something good.'
Haruto furled the scroll back once more and quickly stowed it away for the time being, opting instead to pull out Kakashi's journal about practicing fire release as he began reading through it to improve his own flame's temperature.
"I see… so the rest of the first half of the journal is about Kakashi's understanding of the element of fire… how it is created, how it flows, how it burns, how it spreads, how it exists by feeding on everything… It's a philosophical and practical journal to improve my own understanding of the element. And after that comes advanced Fire Nature Transformation training techniques."
Haruto didn't waste any more time and began reading through the entire journal, absorbing every experience Kakashi had with the fire to make it his own.
Meanwhile, back in his home, Haruto's clone was practicing the Leaf Concentration Exercise.
"This is getting boring…" the clone mumbled with a single leaf stuck to its right palm.
After having the leaf stuck to his palm for the last two hours, the leaf concentration exercise no longer took conscious effort. It was much like riding a bicycle, once you got the hang of riding without balancers the act became instinctual.
And trying to train an instinctual act was often boring, with only repetition and experience making it better.
"How do I make things interesting without using up too much chakra and popping early?"
The clone frowned in focus for a while, looking at the leaf in its palm before knocking its forehead with its other hand.
"I know! I can train the leaf concentration exorcise on my left hand as well."
The clone quickly picked up another leaf from the table and stuck it to his left palm.
It was a little difficult for the first half an hour, as the control on even his right palm where he could stick a leaf for about two hours wavered, with the leaf exploding to bits but he eventually got the hang of things after shredding about twenty leaves.
"I over estimated the difficulty… now that I've got a hang of how to control my chakra in the tenketsu, it doesn't matter which tenketsu I train using, it's all the same."
Haruto's clone looked at the leaves on the table and quietly stuck them all over the different tenketsu on the body he could reliably point out.
But once he had sixteen leaves sticking all over his arms and legs he ran out of leaves and patience to do something so boring.
Instead Haruto's clone got up from the chair and dragged back to the table the textbooks he'd been given by the village.
"I think I have a grasp of the basics of chakra control… I can now study the three basic academy jutsu can't I?"
Haruto flipped open the pages with a clear zeal in his eyes as the leaves fell away.
"The three basic academy jutsu are taught in progression as follows, the transformation jutsu, the clone jutsu and the substitution jutsu. This is because the jutsu are a steady progression built to expand on the others before them."
"The transformation jutsu is the most basic and it involves using chakra to create a three dimensional projection around yourself to create the appearance of a transformation."
"The clone jutsu is just the transformation jutsu but moving the projection away from the body to create an intangible clone."
"The substitution jutsu is just the clone jutsu but applied to an object to make it a stand-in in your place in case you're ever cornered and need a diversion. Typically a wooden stump is used as the object of transformation so that once it is transformed, it can take a few hits in your place before dispelling."
"These jutsu are the hardest to learn since you need to understand the least chakra density of these jutsu by trial and error. But once you learn these jutsu, most other jutsu will come naturally to you."
"To use the transformation jutsu, one must knead chakra while thinking of the form they want to create. Then the transformation jutsu uses the help of the three tenketsu in the brain to gather the current intentions of the caster to give form and colour to the chakra that will be expelled as a transformation after the newly created chakra passes through the rest of the tenketsu."
Haruto's clone frowned.
"I remember Naruto transforming the Toad Boss Gamabunta into the nine tailed fox in his fight against Shukaku. And then the transformed toad was able to hold down Shukaku… So is the transformation jutsu tangible like the shadow clone?"
"Well, only one way to find out…"
The jutsu diagram was below the explanation and the clone looked at the tenketsu to fill with chakra for the transformation jutsu and attempted it immediately.
"There are about thirteen tenketsu used in the jutsu… let's try filling each of them with as much chakra as possible first."
The clone took time, about fifty seconds to circulate chakra to the right spots in its body before filling the right tenketsus.
"Transformation Jutsu!"
There was a small puff of smoke that released from the clone as excess chakra was expelled from the tenketsus before the transformation happened.
TThe clone quickly rushed up to a mirror and looked at the result.
"Eughhh…what is that supposed to be? A zombie?"
Nothing to say. The transformation failed. Spectacularly.
The clone had aimed to transform into the best pirate he had ever seen, only to end up like some murder hobo beaten up after getting high on drugs.
The clone poked its own body at the transformed parts but its hand went straight through the transformation.
'So it ain't solid…'
'I wonder what modifications Naruto did to the jutsu then…'
Dispelling the transformation was easy, just break the chakra circulation keeping the tenketsu filled with chakra and the transformation would dispel.
The clone did that and collapsed onto the sofa.
'Each tenketsu can hold innumerably many amounts of chakra in it… and there are thirteen tenketsu in the jutsu… that means there are virtually an infinite amount of combinations possible before the jutsu works properly.'
'...I can see why it takes the academy students six years to complete just these basics at the academy…'
'And yet there are monsters like Itachi and Kakashi who finish the academy in under six months…'
'Wow.'
