The End Is Coming, but I Wake up and Lie Down System

Others were fighting zombies and building bases in the apocalypse, but I was forced by the system to lie flat for ten hours a day. The neighbors laughed at me for being a loser, until the zombies came, so I lay down and upgraded the absolute defense field. They knelt outside the field and begged me to open the door, and I rolled over and continued my nap.
