This is the second part of the Doomsday Villager map. You find out that the Mr. Spot you killed was a robot. You tell a proper adventurer about this and he goes on a adventure to kill the real one. He tells you that he found a random sign near a desert but
he can't read it so he asks you if you could read the sign for him. You tell him that if you read the sign for him you takeover the adventure!
