You dig rock, wait for falling the tunnel that fills with soil. So far so good if we speak about mines.
If I dig on top of a surface...
with the blue sky above and open for the eyes of the gods.
I know more or less how the matrix works.
But please, oh you holy gods, why let you fall soil out of the air on the top of the leveled rock. I spent all of my blood, sweat and tears of this hard work to you. What did I do wrong that you send me soil out of the blue sky back on my done work, on the leveled and naked rock? So I have to clean the place again.
And why i cannot directly build on top of the rock?
I bid you farwewell... would there be a way to solve this?
