Carving machine instructions into sky jade was an exercise in extreme micro-lithography.
Lin Tao laid the sixteen-inch white jade blank upon a bed of damp river sand inside a shallow wooden tray. The sand served as a sound damper. It took in moving blast waves that could cause tiny cleavage fractures along the stone’s crystal-clear planes.
Beside the tray sat a small earthen lamp filled with refined sesame oil. Its single cotton wick burned with a steady, smokeless yellow flame. Doctor Su stood to his left. He held a magnifying mirror of polished silver that focused the lamp’s light directly onto the white jade facets.
Lin Tao held his star-white-gold metal pen between thumb and forefinger. He gripped the metal just above the micro-needle.
“The original text commands the heavens to sweep four hundred million lives into the void,” Lin Tao said, his voice quiet in the dim chamber. “Our replacement text consists of ninety-two bytes of executable machine instructions and thirty-six bytes of exact ballast.”
“What does the ballast do?” Doctor Su asked, her hands steady as she held the silver mirror.
“The ballast balances the weight,” Lin Tao explained. He kept his eyes fixed on the blank stone. “If you change a decree from ‘kill’ to ‘halt’, the sum of the letters is lighter. The validator will weigh the decree, find it forty grains short, and execute the messenger. The thirty-six bytes are dead weight—neutral marks that restore the exact remainder without altering the command.”
