The smell of crushed red stone mixed with turpentine was sharp enough to make a man’s eyes water.
In the underground depths of Sub-Vault Zero, Shen Yue was suspended twelve feet in the air by three thick hemp ropes looped over the iron ceiling beams. She hung horizontally, her body parallel to the raw granite roof. She held an eighteen-inch horsehair brush in each hand.
Her left hand was painting silver-iron current-carrying ink into a logarithmic spiral.
Her right hand was painting red stone dampener runes in a linked snake-like wave.
Neither hand paused. Neither hand crossed the path of the other.
Between her eyebrows, a faint, crystal-clear bifurcation flickered beneath the skin. Her divided soul running at ninety percent mental capacity.
“Thread A: loop flow pushback ninety-two ohms,” Shen Yue gasped, her voice hoarse from swallowing paint fumes for eighteen nonstop hours. “Thread B: moving grounding trace anchored to the western load-bearing pillar. Lin Ke... The traces are colliding at node forty-four!”
Lin Ke stood below on a wooden scaffold. He held a charcoal slate covered in algorithmic schematics.
