Silent All Day Long

(The text is better than the introduction) I thought being strangled by the monster in the white mask was just a dream, but I found that I had already fallen into a strange world. I thought that passing through the gate was the end of everything, but I found that we were just tiny dust in the sunless city. I thought humanity would win, until the sound of gunfire shattered the illusion; I thought humanity was doomed until a path emerged from the rain. It's just that I have forgotten that I have always considered myself a human being. (Allergen tip: No harem, no concept, God Has Many Knives, first person, the plot is greater than the writing, the battle of wits is greater than the combat, so please proceed with caution)
