God Of Creation System - FirstBorn

A young man at 21 died in his sleep and when he woke up all he can see is an endless black void. I am a beginner writer, so, please don't mind if there are some basic mistakes especially some grammar and sentence structure. Ps: I do not own anime, manga, and novels mentioned in this novel I only own my OC or OC's. This is just a fanfiction:) I don't own the book cover, so if anyone has issues about it let me know :)
