A gray fog engulfs the world, a lighthouse hangs high. Zhang Yang transmigrates to a post-apocalyptic world, ending up in a slum. Unable to pay rent, he faces being thrown out to feed the monsters. Fortunately, he's bound to a simulator; by consuming spiritual energy, he can deduce a lifetime and receive rewards! Zhang Yang simulates the future daily, cautiously trying and failing, searching for a way to survive, and uncovering the truth. Suddenly, he looks back and realizes he has already broken through the gray fog and fought his way through the apocalypse… This book is also known as: "Surviving the Apocalypse, Luckily I Have a Simulator," "Simulating the Future a Thousand Times, Emerging with a Single Life," and "Simulating Godhood, Starting from the Post-Apocalyptic Slums."
