For a few hours, Zech worked the ore crushers. His clothes and all his exposed skin had a layer of soot and dust covering it. He didn't mind, though. For months, he had been taking small amounts of coal dust and mining explosives. In his spare time, he'd mix them up, creating a primitive but powerful form of gunpowder. And now every cart he'd been assigned for the past few weeks was laced with it. Today, he put in his finishing touch. In order for the mixture within the ore to ignite, the temperature had to reach at least 500 degrees Celsius. Fortunately, he had just the thing for the job. C4. He'd hidden a block of C4 inside the storage compound about an hour ago, and on his last trip he'd simply attach a timed detonator and walk away. The resulting explosion would have the explosive force of a few hundred pounds of gunpowder with millions of fragments of ore as shrapnel. From there everything would be up to his captains. The makeshift weapons had been secreted away, most if not all humans in the complex were ready to spring. In 13 minutes and 47 seconds, humans would strike back for the first time in centuries. We will show them that the human spirit will not be dominated.
