The concrete floor in cosmic radiation test laboratory 7D quaked slightly. Equipment juddered along benches and desks. A soft roaring sound was just audible, its volume increasing in tandem with the ferocity of the quakes. Cracks began to appear across the floor, with little splinters of concrete flaking off to jump and spin across the now-unstable surface. Ceiling-mounted cameras scanned back and forth. But the only illumination in the laboratory was a pale amber emergency lighting that had come on after the complex generators had been sabotaged. It provided a poor resolution.
Seconds later, the floor disintegrated, with vast chunks of concrete whirling upward, their molten edges throwing off glowing droplets. Beneath the torn rift a dazzling jade-white light poured upward to blind the cameras. Small tendrils of energy followed an instant later, scratching and clawing at every neutral surface, vaporizing metal and obliterating plastic and glass.
Then the light went out. An Alamo Avenger heaved itself up and out into the flame-shrouded ruin of the laboratory. Its head swung around to focus on its goal, casually demolishing a wall and several support pillars. Chunks of masonry and the shattered floor of the upstairs laboratory crashed down, only to slither and bounce off the armored monster’s force field. The six legs shifted around, turning the body until it was lined up behind the head, pointing directly toward the gateway. It moved forward, slowly at first, smashing through another internal wall. Gradually it built up speed.
As it charged through the constructionbot maintenance center, the floor ruptured underneath its feet. Slightly off balance, it lumbered onward for a few meters, then stopped and twisted its head around to see if there was any threat. Impenetrable jets of dust gushed up from the new rip in the ground. Then a second Alamo Avenger pushed and forced its way out of the tunnel. The first waited until it was level, then they began their final charge toward the assessment building and the gateway.
The café was utterly silent as Alessandra Baron’s overawed voice announced the rise of the spaceplanes. Adam realized he was licking his upper lip in anticipation, and hurriedly stopped. The images shifted from the smoldering land around the complex force field dome to a clean graphic of the assembly platform’s orbit around the planet. In conjunction with Baron’s now-somber voice they illustrated the impending destruction. Figures in the corner of the screen counted down. They almost matched the timer in Adam’s virtual visual.
Second Chance had at most another four minutes. He took a quick look around the rapt faces of the other customers, seeing horror and fascination in equal amounts. For once he didn’t feel any guilt at what he’d done. There were no innocents in the assembly platform, no children devoid of memorycells. Not this time. This time it would be right.
Someone working for Baron’s show managed to access the microsat geosurvey observation swarm around Anshun. Thousands of tiny solid-state sensors along the equatorial orbit shifted their alignment from the minerals buried far below to one specific speck of light. The assembly platform swam into focus at the center of the screen, a giant blue-gray sphere of malmetal. Its featureless symmetry gave it a strangely organic appearance, Adam felt.
Dark lines appeared on the surface, illustrating long petallike shapes. Adam blinked, leaning forward. They hadn’t been there a second before, he was sure. Then long, slim fantails of snow-white gas were shooting out from the spherical surface as the dark lines split open. Sunlight poured into the assembly platform, erasing the weak glow of emergency lighting; the starship’s incomplete superstructure gleamed silver-white at the center of an expanding cloud of vapor.
“No way,” Adam groaned. His timer read a hundred fifty seconds until impact.
Two plasma rockets ignited, wiping out the image in a white nova of super-energized particles. Both exhaust plumes blasted straight through the shell of folded malmetal, sending twin spears of light stabbing over a hundred kilometers down toward the planetary surface. Some of the plasma plume rebounded off the surviving structure, billowing backward around the starship and its swath of girders. Insulation blankets and cables lashed around as they dissolved back into their component atoms, while support girders melted away into pliable strings that stretched like hot cheese as the starship started to move away from the gateway. Component cargo pods ignited, shooting out from the stellar inferno like lurid orange comets, trailing a fluorescent haze behind them as their contents blazed.
