Absolutely fantastic. That was all that John thought.

"This might be hard to choose from."

John, no matter what, would pick , which left 3 spots left to choose. would play an important part in connecting his attacks and causing massive damage to the demons he might face in the simulation. So would also be chosen. would also be chosen for the boost in combat effectiveness. The increase in concentration span was also another reason, but the most important reason was because of the slight time dilation. That effect might sound small, but although slight, it might still serve as a life-saving grace at some critical moment. Apart from the three, he also wanted to pick either or , but the problem lies in the fact that he wasn't sure if mana could be used in the World of Demon slayer, so he wasn't going to risk it.

"System, i select,, and "

[Confirming choice....Start simulation][YES/NO]

"Yes."

[Starting simulation....Altering timeline]

[After your defeat...]

"Wait, what?"John asked, puzzled at the sudden development.

"What do you mean defeat?" I was killed by Muzan."

[Yes, you were killed by Muzan but let's not forget that this World has a fixed plot, but your interference which allowed the Kamado children to escape from Muzan's clutches, leading to the current situation.]

"So what you're trying to say is that this is due to a plot twist."

[Yes host]

Unauthorized reproduction: this story has been taken without approval. Report sightings.

"Anyway, continue."

[After your gruelling defeat at the hands of Muzan, although you suffered gruesome injuries, but due to the effects of you recovered in two days. You immediately set off in search of the Kamado children. Due to the plot twist, although safe, Nezuko had still transformed into a demon, and Giyu Tomioka would have tried to restrain her only to be confronted by Tanjiro, who impressed him with his combat intuition. Convinced she wasn’t a threat, Giyu guided them to Sakonji Urokodaki on Mt. Sagiri]

[With that in mind, you rush to Mt. Sagiri, to catch up to them. You finally arrive after 3 days of running, and climbing the mountain you reach the precipe, there was a single house with rocks on the roof, outside was Tanjiro swinging his sword while sweat covered his entire body, beside him stood a man wearing a haori with clouds imprinted on it, what was really peculiar was the mask he wore a red Oni{Devil/Demon}mask, that man was Sakonji Urokodaki the previous water Hashira before Giyu Tomioka.]

[You walk up to them. You were only 6 feet{2 meters} from them when Urokodaki looked up in surprise, and in his eyes, you noticed narrowed in suspicion. He was on guard immediately, as expected from the previous water Hashira, but you didn't expect stealth to be so powerful]

[Tanjiro stopped his training as soon as he recognised you to be his family's saviour. He introduced you to Urokodaki, who at the time seemed to stop looking at you vigilantly. He also introduced himself to you. He also asked about the katana you had sheathed at your waist. You simply explained that you were a foreigner who had an interest in Japanese culture. He didn’t believe your story, but he didn't refute you . You enquired about the children. Tanjiro quickly told you that his senior had taken them to a safe place.]

[Urokodaki invited you to stay for the night, you readily accepted. During dinner, you expressed your intention to learn under him and for him to take you as an apprentice. He refused you almost immediately, saying his sword style was unsuitable for you. You didn't get angry, you just finished your food, said thank you for the food and then went to sleep, on your way you passed by a door which appeared to be locked tight, you looked at it a nd decided to ignore it.]

[The next day, you got up early to begin training, because due to the combination of and any physical arts he trainedl he would have a 5× boost in learning speed and combat effectiveness{500%}, the effect was truly amazing.]

[Your STR and VIT have increased by 2 points each]

So, training in the simulation could affect him in reality. Well, that was to be expected, with this system, he couldn't really be surprised anymore.

Unlike other systems he had read about. There were 3 types of system's, the fantasy type, scientific type, and urban type. Although this one seems to be part of the fantasy type, it also has a feel of the scientific type, which somehow made it a hybrid. It was his desire that had manifested these traits it possessed.

[From afar Urokodaki witnessed your training, noting your lack of posture but adequate power behind each strike. He watched for a minute or two before walking away. Meanwhile, you continued your training for about 3 hours, and the sun finally appeared on. The horizon, you finally stop swinging the sword, during that period you had swung your sword 30,045 times.]

[Your STR and VIT have increased by 20 points each]

[The fatigue that had accumulated, dissolved in an instant due to the effects of , you picked up your katana, as you walk back to the house, you encountered Urokodaki by the entrance of the house, he stopped you on your way.]

[Immersive simulation activated. Urokodaki's Conviction][YES/NO]

"Yes," John said without hesitation.

His vision suddenly changed as a man in a cloud imprinted haori with a very ugly red Oni mask.John composed himself instantly. The man in front of him was the terror of many demons, Sakonji Urokodaki

"Why did you lie, you assassin." He said in a light voice.

"Why would you call me an assassin?" John was genuinely puzzled.

"Your level of concealment is truly extraordinary, but unfortunately, it seems to have become a habit, even while we converse you stilqyour presence." Urokodaki said as he sighed.

"...would you believe me if i said it was subconsciously done." John said as he scratched his nose out of embarrassment.

"But believe me, I'm not an assassin." John almost shouted in desperation. If he and Urokodaki were to get into an argument and fight, the probability of him getting a better training in the art of breathing would drop drastically.

"It's a condition I've had from birth, even my parents..."

"Why do you keep lying?" Urokodaki cut him off.

I'm Fucked, that was the exact thought running through his mind right now. He could literally see his dream of learning a breathing technique grow wings and fly away right before his eyes. John could only grit his teeth in acceptance as he turned away.

"Is this how strong your resolve to learn under me is?" The voice behind him questioned.

"I just watched you perform 30,045 swings in order to hone your body, to the synergy of that sword in your hand, only for you to turn away with a single accusation.""How disappointing "
