To diagnose a locked system, an engineer doesn’t shout. He listens to the line noise.
Lin Tao knelt on the flat, gray floor of the sandbox, steadying his body against the irregular gravity that tugged at his mantle like a playful ghost. His hardened left collar bone throbbed with a persistent, dull ache, streaming down into his shoulder blade. The body reminder of his mortal vulnerability was welcome. It anchored him against the floaty, unnatural physics of the isolated container.
He held his land-mapper metal pen with two hands, resting the heels of his palms against the cold dark rock floor for balance.
The four-inch shaft of cold-drawn hard dark metal steel was cool to the touch. Its polished surface reflected the faint amethyst glow of the ceiling. At its tip, the pure-crystal star-white-gold plumb needle projected three-quarters of an inch, narrowed to a point measuring less than twelve hair-fractions across. This was not a weapon forged for slaying beasts. It was an audit probe designed to sample potential differences across Precursor circuitry.
Lin Tao leaned forward until the needle tip touched the inner facet of the cube.
The moment the white-gold touched the sharp-angled glass, a cascade of test readouts flooded the tracking data HUD in Lin Tao’s left eye nerve.
