Moving earth was fundamentally a question of mass, traction, and blade curve.
Inside the shaking steel cabin of Steam-Crawler Zero-One, Giles Croft reached across the central console and grasped the main high-pressure control lever for the front blade.
“Corbin, drop the main compound gear into low-range,” Giles directed.
“Twelve hundred revolutions on the turbine. We need maximum torque at the final drive sprockets, not speed.”
Foreman Corbin Cross hauled back on the twin reduction levers. The world-size gearboxes engaged with a deep, metal thrum, channeling six hundred horsepower directly into the hard dark metal-steel track shoes.
Outside the two-inch quartz ports, thirty blind cave-drakes were swarming the vehicle’s front chassis.
The armored reptiles hissed and snapped, their hardened jaw plates striking sparks against the radiator guards. Two twelve-foot drakes had scrambled directly onto the front fender, their curved climbing claws tearing futilely at the solid hard dark metal plate.
Giles shoved the high-pressure blade lever forward.
