A World Where Wishes Come True

They say that beyond the mountains, beyond the sea, in a ridiculously faraway place, there's a machine that can make your every wish come true. Find it, tell it what you want, and your wish will be granted. But nobody has ever found it.

That's what the locals in this world say. But as someone who transmigrated here from another world, I can tell you for certain that this world has changed twice this week. Now I have to find that damn machine and change the world back.
