Cataclysm: Day of Darkness

The world is destroyed. I don't know what caused it, but suddenly everywhere was invaded by various monsters. Maybe there are still people alive, maybe humanity is finished long ago, the cities are filled with dead people, and worse things are brewing in the wilderness. Civilization is gone forever, and no matter how miserable or successful they were in the past, those who survived should be prouder than ever of themselves. Compared to the vast majority of people in the world, at least there are tens of millions of people who were once human. After the cataclysm, the world was turned upside down. In this devastated world, demons are dancing wildly. In the endless evolution and invasion of monsters, live and then die. This novel and its characters are purely fictitious.
