At the End of the World, I Rely on Simulation to Become Invincible

When he woke up, Lin Xuan suddenly discovered that the world was about to end! But he's not worried at all because he has a doomsday simulator! The doomsday simulation begins... On the first day, the apocalypse breaks out, and you, who are unprepared, are directly clawed to death by the zombies that break in! Ahem, although the death rate was a bit high, Lin Xuan received the reward after the simulation, a Desert Eagle with unlimited bullets! Moreover, there were a total of ten simulations before the end, and at the end of each simulation, Lin Xuan could obtain the same skill or treasure! … So when the ten simulations ended and the real doomsday broke out, Lin Xuan found that he was almost invincible! Lin Xuan: "How lonely it is to be invincible. The zombies will take another punch from grandpa!" Both humans and ghosts are showing off, only zombies are being beaten! Lin Xuan: "I'm not a devil. Of course I won't fight zombies when I see them. Just like beautiful zombies, I usually possess them... Ah no, I will protect them." Lin Xuan: "My purpose is to pick up... No, to fight zombies and maintain world peace!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
