After spending the day cleaning up his family compound, Sasuke made a brief trip to the market using some of the pocket money he had collected. He returned moments later with a handful of groceries.
Whilst the Sasuke in his memory couldn't cook, with his memories of Ren, he was more than capable of preparing some food. In the quiet of his kitchen, he deftly prepared a comforting bowl of miso soup, which he swiftly devoured.
With dinner now consumed, Sasuke found himself collapsing onto his futon.
The day had already turned to evening, and he felt his sleepiness tug at his mind. Yet, before succumbing to sleep, a familiar habit from his previous life nudged at him—the need to plan for the day ahead.
As he lay there, thoughts drifted through his mind like shadows.
"What should I do tomorrow? There's no need to attend ninja school for the rest of this month, for rather obvious reasons. Perhaps I should test my ability to reproduce the Ninjutsu and Taijutsu that the former Sasuke learned."
"Would I inherit his ability? Or would I need to relearn everything? That would be an absolute pain..."
"And then, a discussion with the Hokage is in order, exploring the possibility of accessing the Uchiha clan's family financial resources—assuming it hasn't all been robbed already."
As Sasuke mulled over these considerations, he began to slowly close his eyes, allowing the quietude of the night to envelop him.

As time unfurled its passing, morning arrived with sunlight gently lighting up the desolate Uchiha compound.
Groggily rising from his futon, Sasuke refreshed himself. Passing by a mirror, he confronted the reflection of a young boy, not even ten years of age.
The child's countenance bore the hallmark Uchiha traits—cold, obsidian eyes, unruly black hair that was gravity-defying, and with that a face that belied a maturity far beyond his years. Delicate features and fair skin created a visage that might have been mistaken for a girl if not for the pronounced boyishness present in the child.
In a moment of narcissism, Sasuke marvelled at his countenance. However, his musings veered towards something else.
'When did I get so strong?' The swift cleanup of the entire Uchiha family compound in a single day seemed incongruent with Sasuke's memories.
As he slowly focused his attention on his chakra, he sensed a reservoir far surpassing what he had known before inheriting this body.
The chakra, though not on par with the levels of his father or brother, surpassed his previous understanding – now a formidable 30% of their capacity, a remarkable leap from the original <5%. This placed him well within the range of a Jonin.
'It couldn't be...' Shock tinged Sasuke's thoughts as he glanced at the mirror and he soon began to focus chakra into his eyes. Suddenly, time seemed to warp, and the world around him unfolded with unprecedented clarity.
Reflected in the mirror were eyes that glowed with an eerie crimson intensity, adorned with three ominous black tomoe encircling the pupil in a distinct ring. The Sharingan stared back at him, its presence eerie and unsettling.
'A 3-tomoe Sharingan?' Sasuke's mind raced as he contemplated the anomaly. According to his recollections, Sasuke had only awakened the 3-tomoe Sharingan during his fight with Naruto at the Valley Of The End.
'Even if I unlocked a 3-tomoe Sharingan, it doesn't explain this absurd surge in chakra.' Sasuke contemplated the incongruity, as chakra typically increased with age and consistent training, making his newfound strength inexplicable.
With an unsettling thought appearing in his mind, Sasuke poured chakra into his eyes once more, witnessing the evolution of his 3-tomoe Sharingan into a new pattern. It sported a vivid black iris in stark contrast to the intricate scarlet pattern within, glowing with a piercing luminescence.
"Damn." He muttered to himself. "Did not see this coming..."
