Chapter 242: Chapter 242: Rules of War

After three weeks at City Titan, The Outer Artillery Proving Grounds

Ragnar crossed his arms over his blackened breastplate. Three weeks had passed since the catastrophic firedamp explosion had nearly severed the empire's critical coal supply in the Western Deep Vein.

Ragnar and Chief Engineer Ludwig had successfully stabilized the collapsing shafts by deploying massive, steam-powered centrifugal fans. By constantly pumping fresh, high-pressure oxygen deep into the subterranean tunnels, they had effectively purged the invisible methane gas, allowing the highly disciplined Tang laborers to resume their furious extraction of the precious anthracite coal.
