Sasuke continued his journey home with questions swirling in his mind.
'Could this heightened perception be due to my reincarnation? Perhaps it's associated with my soul. Does this mean our souls truly merged instead of me replacing Sasuke, as I initially thought? If that's the case, what else does my stronger soul indicate? Perhaps it could affect my Genjutsu and Yin Release?
I'll have to test that at a later date. Would this also explain my Mangekyou? Sasuke's ardent desire to think that everything he saw that day was fake, combined with Ren's grief and his desire to escape the physical world, forming my current Mangekyou ability?'
As Sasuke entered his family home, the gazes following him finally disappeared. However, he was certain the people behind those gazes didn't simply vanish and were probably outside the Uchiha compound, monitoring him.
Breathing a quick sigh of relief, Sasuke headed towards the kitchen to make some lunch for himself.
After lunch, Sasuke then went to his room and took out a small piece of chakra paper. 'With this, I'll be able to find out what my chakra attributes are. Then I can focus on which attribute Ninjutsu I should practice with,' Sasuke thought.
As Sasuke injected his chakra into the paper, a change occurred. The originally pristine piece of paper began burning at the top, while the lower half began to wrinkle.
'Fire and Lightning Attributes.' Not unexpected, Sasuke thought as he stared at his now empty hand. However, he was glad that these attributes somewhat complemented each very well as Fire would counter Wind which was the weakness of the Lightning attribute. And though Lightning didn't exactly counter Water which is strong to Fire, it does offer an alternate method of attack against it.
Sasuke then headed towards his parents' bedroom, not to reminisce but to look for something. Once in the bedroom, Sasuke reached towards a specific wooden floorboard in the corner of the room and lifted it. Within a hidden space were several scrolls depicting practice methods for Ninjutsu, Genjutsu, Taijutsu, and even a summoning scroll.
'Didn't think I would have to use this hidden stash,' Sasuke thought, gently shaking his head. This secret space was originally there just in case something happened to Sasuke's parents, but he never actually thought there would be a moment when he would have to use it.
Sasuke soon activated his Mangekyou, engraving all the images from within the jutsu scrolls into his mind. He then returned them to the hidden space and covered it up with the floorboard again.
Sasuke decided that, for the time being, he would simply focus on C/D-Rank Fire Ninjutsu, conditioning his body, practising chakra manipulation, and hand seals. Though the lethality of Fire Style Ninjutsu left much to be desired in his memory of the anime, Sasuke chose this instead of Lightning Style Ninjutsu due to there being an abundant collection of it in the secret compartment.
He decided not to practice Taijutsu or Genjutsu for the coming month. Instead, he would opt for more immediate methods to increase his combat power by abusing his vastly increased chakra reserve.
Taijutsu could be quite easily copied by his Mangekyou, though he wouldn't be able to exactly replicate certain movements due to differences in body size and structure, it would certainly accelerate his learning in it.
For Genjutsu, Sasuke already planned to practice it around the time he goes back to ninja school next month.
Sasuke then began to head towards a training ground near his home, within the Uchiha clan compound. Upon arrival, he found himself a large tree that was around 15 meters tall on the side of the training ground. Focusing his chakra on his feet, Sasuke tried walking up the tree vertically, a method that exercised chakra control from his memory of the anime.
Just as Sasuke braced himself for a fall, he paused and looked down at the ground.
'I'm assuming this should also be due to my powerful soul?' Sasuke was lost in thought for a second. His memory in the anime indicated that Sasuke wasn't particularly talented at chakra control, depicted by how he didn't pick up on chakra control exercises too easily, though his chakra control did improve rather significantly later in the anime.
Now that his chakra reserve is so much bigger than before, it should be harder for him, in theory, to control his chakra.
Just as he recollected himself, he looked at the ground again and found that the ground seemed to be getting closer to him.
'Wha-' Sasuke exclaimed in his mind.
Uninjured but embarrassed, Sasuke quickly tried to pat the dust off while remembering the stinging gazes that followed him to the training ground. He just hoped that they had a lapse in their attention and didn't see that.
'Lesson learned, I should probably stop my thoughts from wandering when I'm practising, especially with chakra.' Sasuke mused
After attempting the task again, Sasuke tried to clear his mind and focus on his chakra that was being channelled to his feet. He slowly inched towards the top of the tree and soon reached it. Sitting down on the branch next to him, Sasuke let out a sigh of relief as he could finally let his thoughts wander again.
Sasuke then carefully got down from the tree and positioned himself at the centre of the training ground. With his hand close to his face and fingers forming a circle in front of his mouth, Sasuke then inhaled and carefully channelled his chakra to the air in his mouth, following the steps in his memory.
'Fireball Technique' (火遁・火球の術, Katon: Kakyū no Jutsu)
A fireball, measuring about 2 metres in diameter, shot out of Sasuke's mouth. It travelled across the training ground before hitting a tree in the distance, leaving a large black scorch mark across the tree's bark.
