I Am the Host in a Horror World

Did you know that your friendly neighbor next door watches you through a small hole every night? ! ! Ps: Humanity is completely defeated and can only huddle in a building with a human landlord, but you don't know when a monster has sneaked into the building, disguised as your neighbor or friend, and waits until night falls to kill you... The higher the building, the more people there are, and the taller the building, the more powerful the monsters... This novel and its characters are purely fictitious.
