The end of a good post-apocalyptic novel should not be too short. It would be best if there was a system that could refer to the following suggestions: 1 " The Road to Doomsday " 2. Survival in the Afterlife 3 Mr. Zombie 4 Doomsday City [Zombie King] 6." Rebirth at the End of the World " Zombie War 8 Zombie Blade [Doomsday Special Ability] 10 " The Revival of the Zombies in the City " The above novels are all completed. Some require a certain level of reading foundation, but they are all system style doomsday novels. I hope they can meet the needs.
