Honestly, just starting a new novel would be much better. New powers, new character, new world, new harem. I really can't see him and his huge family universe hopping, he already has a family more so when he never intends to stop expanding it. Even if you only try to ground it to apocalyptic worlds only, then what about his family? Would they agree to jump from the frying pan into the fire? The story doesn't really have to end in a big bang, he doesn't have to be the messiah saving humanity, great leader uniting america and the pillar for the rebuilding of society. You can just let him build a sanctuary, a central hub for survivors all around and their settlements. Wait out till every Zs decay and implement a safety checkup system to prevent accidental or natural death caused outbreak. Just let humanity rebuild itself while he can just enjoy his life with his family. If you have read the comics there is a whole functional town/city still barely holding on (last I've seen) so you might still have more to explore in this world.
If it is a multiverse story i hope you continue doing what u did for this story with 100 chapters that way you can pretty much get through the whole show or movie cause some multiverse story u know they spend 5 chapter there and the leave but if you do what u did for this part of the story it should be pretty good
maybe a new fic? coz if you plan to continue this for a multiverse travel it will be limited to worlds that has a zombie troupe in it, or apocalyptic per se. It will not make sense if he will travel to worlds that is not experiencing the same kind of situation like with TWD. If u continue with this idk bout the worlds though. either ResidentE?, Dying Light, Dawn of the Dead, i am Legend?. Problem is the characters, so most likely a world where ppl know the characters lest they will not understand a thing on that particular world. Or maybe an apocalyptic world like Fallout? Just put some well known characters from different series, games or whatnot. Though that will be a clusterf*ck and thanks as always for the chapters. Goodluck
You already doing a great job writing this story as it is, adding a multiverse hopping feature would just complicate this for ya and probably ruin it for your readers. Besides you could just write another fanfic integrating apocalyptic multiverse only from animes movies and series, maybe even an original apocalyptic world of your design, and I'd go as far as speaking on behalf of most of us here that we'd love to read another of your works man and thank you for your hard work. Much appreciatedđđ
Continue with this and complete it. Once you start adding other universes it will become confusing. I really enjoy reading your version of TWD. You can always write another story about John in different universes. You should complete this instead of having him go through a whole bunch of different universes. It will become less interesting and to confusing. Thanks..
I prefer it to be another book. First give the MC a good ending to his story. Then start a new book with a new character, new cheats and new harem. It's good for us to see another amazing story from you and it's good for you to implement your experience and ideas you learned in this book. A win-win for everyone. My request if it's an apocalyptic world would be an MC in the world of Resident Evil, like a mix between movies and games.
