The three meter diameter ship glided around the forest, hunting for granite buried beneath. Its sensors could perceive all frequencies of matter through the planet's crust to a depth of 20 meters. Below that, the layers of vibrational fields merged and became difficult to discern. After a brief search, a suitable granite boulder was found at a depth of nearly two meters, buried over millenia after falling from the cliff above. A lightweight alloy sheet was deployed from beneath the ship and placed on to the side. Using lasers and manipulating the electro-gravitic fields, it cut around then lifted out the upper soil layers. The intact soil clump glided over to the sheet, where its sides were wrapped up in a temporary raised bed. Next, mini laser excavators dropped into the hole to completely free the rock. The boulder was liberated from the Earth and suspended in the air. The blueprint for the size and shape needed from the stone were overlaid on the raw chunk. A few laser cu
