A Hundred Nights of Dreams

When I woke up, I found that the ceiling in my house was gone. Overnight, the world became completely unfamiliar to me. Familiar streets turned into ruins, creatures disappeared, and humans had no trace of their existence, replaced by a large number of pure black humanoid monsters. It's my first time playing this game and I'm inexperienced, so I maxed out the monster's hatred value. After finally working hard to solve them, I met a human being. He squatted on the wall with an expression as if he had seen a ghost. I thought I was going to die because I was torn apart by these monsters, but I didn't expect that I was almost killed by one of his cannons. Do you think this is an apocalyptic novel? No, ko no, just write it blindly! Intention: I didn't know, I just wrote it blindly
