One of the tubes, a linear accelerator, spat out a black sphere that hurtled down into atmosphere, glowed red, then white, and began to ablate. Ten miles up it shed two burning hemispheres. The missile it contained slammed down through a wheat field, igniting a small fire around the surface puncture. A microsecond later, the field bulged up into a hill; it started smoking, then abruptly combusted. Flame jetted from arcology vents within a mile of this, then smoke from those lying beyond them. Crowds of people still moving away along the north-west shore gazed back at debris blasted from the numerous exits in the arcology’s edge. Coloron measured the spread of heat, observed the substructure’s reaction to this latest strike, then sent a map selecting the positions of other reactors, and locations of those enemy materials and energy stores.
‘Interesting,’ commented Brutus.
‘After I have cut the division,’ the Coloron instructed, ‘you must take out all those targets at once.’ The AI knew that, on some level of awareness, the Jain substructure would realize the disposition of its forces had been discovered. It would probably find the HK, but by then the damage would be done.
Incrementally again, the particle cannon tilted. The turquoise beam hit the sea this time, evaporating billions of cubic yards of brine. It sliced into the arcology wall then began to burn across. From orbit a cloud mass could be seen forming in its trail. While still metaphorically holding a finger on the firing button, Coloron noted monitors and Rescue staff loading into AG ambulances those injured by the departure of the crowds at Runcible 5. On the map updated by the HK program, the AI saw that the Jain substructure now lay only a mile away from there. The immediate blast radius around 6 was clear of people, though there were still some stragglers within areas likely to be devastated by the Shockwave. The Jain tech lay a mile and a half away from Runcible 6. Coloron waited.
Half an hour passed, then an access panel for an optical junction sprang away from the wall on the furthest edge of one of Runcible 5’s lounges. Something like a long-fingered stainless steel hand groped out, and began to extend its fingers down the wall. On another wall steel buds grew through sheet bubble metal and squeezed out grey tendrils. The last three ambulances departed, whereupon some other ambulances tried returning, because there were still people alive in here. Too late, because Coloron began closing blast doors behind the departing ambulances. Now humanoid figures began appearing, their clothing burnt and hanging in tatters, their bodies blackened, and pinkish slithing movement visible through their wounds. The AI began shutting down systems as soon as it felt informational intrusion—as it had been doing all along throughout the advance of this feral technology. Soon its total perception of the area became limited to a few scattered cameras. Then came the expected intrusion into the systems of the runcible itself.
The runcible buffers held a huge charge, permanently topped up by the fusion reactor located on the floor below the runcible itself. With safety circuits offline, Coloron released this entire charge into the runcible. A warp generated, tuned out of U-space, tried to create space of its own, bounced out into realspace, then collapsed. It sucked in the horns of the runcible, the dais, the fusion reactor, several bodies—some still alive—and much of the surrounding complex, crunching everything down into a spherical superdense mass. At the centre of this mass: fusion.
From the cannon satellite Coloron observed the subsequent explosion flinging millions of tons of debris into the air. A briefly stabilized fusion reaction dropped a yard-wide white sun straight down to the bedrock. As the smoke cleared, the AI observed a glowing two mile-wide crater cut into the top half of the arcology. Eight minutes later a similar crater appeared in place of Runcible 6.Twenty minutes after that, the particle beam cut its way out from the north wall of the arcology.
‘Now,’ Coloron sent to Brutus.
