Next morning, at 7 a.m., Y/N was seen at the training ground. He had told Sasuke that he would be out for a while. Speaking of Sasuke, he had gotten a little better due to Y/N's help, but unfortunately, he started ignoring Y/N again, slowly returning to his usual personality from the anime.
"Welp, time to train my cursed energy. I can feel it overflowing. And since my cursed energy is the same as Sukuna's 20-finger form,considering I took the first of the twenty fingers in this world—my cursed energy exceeds Sukuna's by 5%," Y/N said, resting a finger on his chin as he smirked thoughtfully.
Y/N stared at his clenched hand. He began applying cursed energy to it, recalling his earlier experience and trying to feel the same sensation again. A faint aura of cursed energy appeared around his hand.
"Tch. I need to improve my mastery to even throw a proper amplified punch,and to use my cursed technique effectively."
Y/N walked up to a tree and amplified his hand before throwing a punch at it. The tree dented slightly.
Frowning, Y/N threw another punch, this time putting his all into it and amplifying it to the best of his ability. This time, the dent was noticeably larger, and a small shockwave rippled outward, causing the leaves to rustle.
"Well, that's more like it... though it still needs work," Y/N said, still dissatisfied.
"Gojo trained Yuji in cursed energy mastery by making him watch movies and control his cursed energy flow. But I don't have a cursed corpse... Maybe I can try channeling my cursed energy into an external object, like a stick, and maintain the flow. Yeah, that could work," Y/N said as he stood under a tree, crouched down, and picked up a fallen branch.
Y/N began attempting to channel his cursed energy into it. At first, he couldn't do it at all. But remembering how he had channeled cursed energy into his fists during his fight with the cursed spirit, he tried to replicate that feeling.
Eventually, he managed to channel a small, slow stream of cursed energy into the stick.
"Yes!" Y/N exclaimed excitedly—though the moment he lost focus, the flow disrupted.
"..."
Y/N sighed in exhaustion and tried again.
He managed to do it once more and this time maintained the flow—though it would still break whenever he got distracted.
.
.
After four hours, Y/N noticed it had become afternoon. His cursed energy flow was much better than when he started, and his output had increased as well.
Y/N dropped the stick to the ground after it broke, unable to withstand the violent cursed energy.
"Dang it. Whatever,my cursed energy manipulation is better now. I should try using my cursed technique since my control has improved," Y/N said to himself as he activated his cursed technique on a tree. Utilizing his output, he flicked his finger as a thin cut appeared on the trunk.
"Huh? I could've sworn it was stronger than that. Maybe it's because I didn't have the intent to kill," Y/N thought. He tried again, this time with the clear intention of cutting the tree down rather than just testing his technique.
A deeper—but still thin—cut appeared.
"Dammit, not strong enough... I guess I should improve my output first," Y/N said with a frown.
Over the next few hours, Y/N improved his output slightly—though it was still lacking. However, his cursed energy reinforcement had improved significantly. He could now leave a decent dent in a tree.
Disappointed with how weak his cursed technique still felt, he decided to sharpen his intent—training himself to always be ready to kill when necessary. To truly understand that feeling, he chose to hunt animals.
He hid in a bush. A short distance away, a deer was drinking water.
"Alright... this should be easy..." Y/N muttered as he watched the deer lift its head.
Seeing its neck exposed, he decided to send a slash at it.
"Dismantle."
Despite his weak output, the neck was a vulnerable area.
Soon, the deer collapsed, blood pouring from its neck. It let out cries that made Y/N's heart ache as he approached it.
Seeing its fear-filled eyes, he whispered, "I'm... sorry for being selfish. But I need this. Sorry."
He put it out of its misery with another dismantle to the neck.
Sighing, Y/N activated his Sharingan and spotted another animal in the distance.
He ran toward it and saw that it was a brown bear. Unsure whether his cursed technique would be effective, he decided to rely on physical combat.
The bear roared and charged at him, likely hungry.
"Come then."
Y/N ran toward it, striking with multiple enhanced punches, causing it to roar in pain.
"Come on, is that all you've got?!" Y/N shouted to provoke it.
The bear roared angrily and swung its paws at him. Though, Y/N dodged before launching A dismantle at it, cutting across its already injured body, drawing more blood as it got sent flying away. This cut was deeper,likely due to his heightened killing intent and the danger he was in.
Sensing death if it fought longer, the bear got up fast despite it's injuries and attempted to flee.
But Y/N vanished and appeared in front of it, eyes focused, killing intent radiating from him.
As he threw a punch, His cursed energy activating at the last second, suddenly turned black.
Upon punching it in the stomach, a rare phenomenon occurred—a spatial distortion that happens when a sorcerer applies cursed energy to a physical strike within 0.000001 seconds.
Known as...

"𝗕𝗹𝗮𝗰𝗸 𝗙𝗹𝗮𝘀𝗵!"
It coughed up blood badly and got sent to the ground, not able to move anymore, its head got severed from a dismantle.
Y/N had entered the flow. Sensing his potential increasing to 120%, he smirked, looking a bit high too.
"This sensation is... God damn amazing! Haha! I've thrown a Black Flash and I feel my cursed energy way better than before!!" Y/N, least to say, was feeling overjoyed and a bit drunk.
He decided to go hunting down more animals to calm himself down. He also landed another Black Flash during a fight with a black bear this time due to increasing his chances of throwing a Black Flash by entering the flow.
.
.
.
After that, Y/N was seen walking back to the training ground, a few scratches on his face. As he reached the training ground, he decided to increase his raw strength, his taijutsu, and how to mix his style with the power of the cursed energy-reinforced attacks.

"99...100!" Y/N said as he completed his set of push-ups and collapsed on the ground, panting.
He rolled onto his back and looked at the sky.
"Haaah... phew. that was intense"
"...hm, i wonder what should I learn with my cursed energy? Maybe divergent fist? Nah.. while it's perfect for my bad control of cursed energy, it's only good as a trick and nor raw power. Maybe try syncing my cursed energy with my punches.. yeah, that could work. But I have to first believe that the mind, soul and body aren't seperate but unified. That's what Aoi todo says, and clearly it's effective." Y/N said while looking at the clouds, his panting less intense than before as he regained his energy.
"But what he says does make sense. The body and soul works together and that's a fact. And the mind IS the one giving orders. So infact, the body, soul and mind are unified and works together, cursed energy does not come from the gut or something but rather the body, mind and soul at the same time." Y/N said, finalizing what he thinks about cursed energy and where it actually comes from.
"So with that fact...." Y/N held up one hand and clenched it. Upon willing, his cursed energy surged nearly almost immediately from his hand.
Y/N, seeing this, smirked. "this definitely will help use Black Flash more often. I guess this means the whole Synchronization is almost or nearly almost mastered, just gotta fight someone repeatedly to fully master this."
Y/N got up from the ground and walked in front of a tree.
"Alright then. Let's see how much I can dish out." Y/N, upon saying this, clenched his fists before amplifying with cursed energy.
Y/N threw a punch at the tree with all he got like how he did yesterday.
A decent, almost big dent appeared on the tree with a weak shockwave bursting everywhere.
"Now that's better. My output sure increased." Y/N stood back before throwing a couple of punches.
Each punch dented the tree decently, making the previous almost big dent, massive. He continued and continued punching the tree, trying to improve the body's synchronization with his cursed energy better.
Throwing another punch, his punch synced with his cursed energy, willing it to activate at the last second.
'This feeling!' Y/N's eyes widened slightly as his cursed energy turned black.
"𝗕𝗹𝗮𝗰𝗸 𝗙𝗹𝗮𝘀𝗵!"
Throwing a Black Flash, the tree got destroyed, falling down immediately from the power of his Black Flash.
Y/N grinned as he looked at his clenched hand in joy of being able to land the Black Flash. His understanding of cursed energy went up higher.
"I can never get tired of this feeling... maybe I could still land a few Black Flashes now that I am in the flow."
Y/N immediately moved from a tree to another, punching them down every time a Black Flash occurred. Unfortunately only one more Black Flashes occurred, bringing the total of Black Flashes thrown up to three.
Due to that, his understanding of cursed energy increased with his output and synchronization, bringing his synchronization up to solid, almost mastered.
Y/N didn't say anything after that. Deciding to call it a day, he glanced at another tree, one that hadn't been destroyed. He flicked his finger with one word.
"𝗗𝗶𝘀𝗺𝗮𝗻𝘁𝗹𝗲."
The tree got cut completely in half. Satisfied with the result, he slicked his hair back and walked away while smirking.
.

Y/N unlocked the door to the house and walked in. He saw Sasuke sitting on the couch, staring at a wall without saying a word.
"...you know. I get that it was a bad experience for you but.. you should give it a rest. Your parents won't like you crying about them. They would like you to move forward too."
Sasuke looked at him in silence before slowly nodding, muttering a thanks, then retreated to his room.
Y/N looked down at the ground before glancing up at Sasuke's room, then headed to his own with a sigh.
