What is the real apocalypse? Everyone is in danger and cannot be trusted, the order is broken and no trace is left, corpses are lying in rivers of blood for thousands of miles, and there is no sound in hell everywhere.
When the creatures we see mutate and become bloodthirsty, and face the giant beasts of the mountains and seas, how should the remaining humans respond?
Where should a programmer and a deliveryman lead to survive?
This book is not about harem, system, or time travel, so please be careful.
