Nothing too intense. Maybe it's about building a base during apocalypse. Or doing some mundane things during the apocalypse or even post-apocalypse I liked: Superstars of Tomorrow Others I know: Reborn Otaku's Code during the Apocalypse Bringing a Supermarket to the Apocalypse (?) The titles may not be exactly the same because I forgot. In anycase, I've tried those novels mentioned above Recommendations can be from NU, SH, RRL or anywhere else. As long as its free to access and isn't a fan fiction.
Apocalypse Lord!! - It's not zombie apocalypse though, but more on monsters etc. World transforms into game world~
