From A mole of moles, I meet this sentence:
Plumes of hot meat and bubbles of trapped gases like methane—along with the air from the lungs of the deceased moles—periodically rise through the mole crust and erupt volcanically from the surface, a geyser of death blasting mole bodies free of the planet.
How to understand the emboldened bit? In either ways to break down it, the word free seems to be out-of-place:
- a geyser of [(death blasting mole bodies free) of the planet]
- [a geyser of death] blasting [mole bodies free of the planet]
It looks like the word free belongs to the phrase mole bodies free, but again, what does it mean? It cannot be an suffix like smoke-free or body-free because it doesn't make any sense to me, plus that in the phrase the word bodies is in plural form.
How should I understand this sentence?
