This is Soul Evolution System: Reborn. The original author Drack21 was said to have died leading to many people asking for someone to pick up his story. There were honestly also quite a few complaints about his original story, because Drack wasn't an English writer and his editor honestly wasn't good with English either. Making his story hard to understand. There's also the fact it was an R18 novel that had about three R18 scenes in the entire story, the first one being almost 400 chapters in. A lot of people liked the concept behind the story he was trying to create but there were a lot of mistakes along the way as he was a first time writer. Therefore after 6 months of people begging someone to pick up the story, I finally said screw it and picked it up myself. The story is about Alexander Ilios Apeiro aka. Alex who is reborn for the amusement of a higher being. He is allowed to traverse any world and do whatever he wants even if he were to choose to help the demon lord instead of fight him in a certain world. As long as he makes things interesting... This is a FanFic, so there will be taking girls from other worlds, it's kinda in the whole FanFic motto if you will. But there is also an original world that will have its own story line in between jumping to other worlds.
