A new life?

"Where am I?" was the first thought I had when I woke up in this unknown environment. I was just hovering in empty space, it was very bright but I couldn't find any light sources.

While i was still trying to comprehend what happened a soft voice toned inside my mind

"You're in my pocket dimension Marcus.".

"Who's there?" I replied.

"I don't have a name but some call me god. You can just call me One tho." (One)

"So does that mean I died? Am I going to reincarnate like in the manga I read?" (Marcus)

"Yes indeed, truck-kun came for you Marcus. Normally your soul would just reincarnate on earth, of course without your memories. But there seems to be a problem with your soul, I need some time to fix that. So in the meantime I'll have you go to my newly created pseudo dream world. An experimental world I created out of boredom. As you are the first person to enter this world from the outside I will give you some form of assistance. Although your soul can never be really extinguished in there your physical body can still die. Fortunately you have me and I will make sure you get revived every time you die as an apology for messing up your natural reincarnation." (One)

"How long do you need to fix my soul? What kind of assistance do I get?" (Marcus)

"Well I read your memories and because you seemed to like reincarnation manga and novel with a system I gave you just that. As for how long I need to fix your soul I am not quite sure about that but you can expect it to take a few hundred thousand years. And you're probably worried that I will just pull you out of your fantasy. Don't worry I will only remove your soul after I'm finished fixing it and will wait till your next death." (One)

"What? No I mean this is incredible long, what am I supposed to do for so long?" (Marcus)

"Well you could try to become a god inside this world. It's totally possible. There are an infinite amount of worlds to explore.They don't even have to be real you can even visit your favourite anime world. Anything is possible." (One)

"..." (Marcus)

"You mentioned that anything in this dream world is possible, does that mean I can alter my body or change my race?" (Marcus)

"Yes before being reborn I'll give you a chance to select out of a few races and you can also modify your appearance." (One)

"I have one last question. Why do you need so much time to fix my soul? How was it even damaged in the first place? (Marcus)

There is a short moment of silence before he started to speak again.

"Well if you have any other question you can ask your system. We'll meet again until then I wish you a wonderful new life." (One)

"Wait you haven't answered my quest-"

Before I could complete my sentence a portal materialized right before me. It sucked me in without giving me a chance to react...
