Inside gleaming metal pipelines, endless streams of resources were being delivered upward.
Thick smoke enveloped the entire passageway, concealing most of the view, but Matthew could still make out the transport vehicles hidden beneath the smoke.
The colossal transport vehicles, brimming with mechanical aesthetics, had astonishing carrying capacity.
