The wall, being nothing more than super-resilent, thick, rock-hard concrete, gives way under the cuts of Joseph's vibro claw. The vibrating blades themselves don't make much noise, barely a faint grating. It's the sound of chunks of concrete falling on the ground that's louds. Those are big chunks.<br/>At certain point the vibro-claw screeches on a mega-resilent metal beam, one of many supporting the bunker dome. It eventually saws trough it and now chunks are falling down from the ceiling too.<br/>Given enough time, maybe an hour, Joseph could saw trough all layers a hole big enough to walk trough, but now he and others hear a new gurgling hiss in the doorway.<br/>The Juicer is first to spot it, second bloated floating shape waving pointy stumps of limbs and coughing with it's multiple mouths. Only Mizrel can understand the thing is chanting.
