An ordinary guy gets hit by a car and finds himself in another world... Posthumously! This world has survived its apocalypse and is now in agony. The plot is banal, I have heard many such stories. This is a world of sword and magic, and also gadgets and nanotechnology - more interesting, but not much. But this magic is not really magic, because magic is something that cannot be explained from a scientific point of view. And agony in our case is not really agony, because agony is the death throes, and our “patient” does not even think about dying.
