Three hours before midnight, Lin Tao sat cross-legged on the shaking dark rock. The brass land-mapper housing was resting across his knees.
The cold was piercing, biting through his dark linen coat and woolen traveling trousers like needles of crushed ice. Above him, the sky was a cracked dome of matte gray. The tearing level seams glowed with the faint glowing soft glow of unrendered wireframes. Beside him, Tie Shan sat sharpening the chisel end of his star-iron cold chisel with a flat whetstone. The rhythmic scrape of hardened steel against stone produced dull, squared-off clicks that died instantly in the dead air.
Lin Tao dipped the pure-crystal star-white-gold tip of his land-mapper metal pen into the white dust.
With steady, razor-sharp strokes, he began sketching a series of sharp-angled diagrams into the stone crust of the shale. He drew a circle divided into thirty-two discrete arcs, labeling each sector with twin register notation: 0x00000000 at the southern origin, 0x7FFFFFFF at the northern apex, and 0x80000000 at the exact point of inversion.
To a royal scholar or a Daoist grandmaster, these markings would have looked like the impossible to understand runes of a mad heretic.
To Lin Tao, it was the simplest, most deepest truth of twin arithmetic. Two’s complement signed integer representation.
