I looked up at him: "Sir, if you kill me now, no one in Daye will be able to make a composite bow tire that can withstand three hundred kilograms of tension."
A female Ph. D. In materials engineering, dressed as an official slave, used her professional knowledge to move the entire era, from smelting copper to making repeating crossbows. This is not farming, this is the industrial revolution.
