The Greatest Tyrant Under Heaven

An overlooked prince happens upon a heavenly book filled with devices and inventions far ahead of their time: steam engines, repeating crossbows, rockets, thunderous cannons, flying-shuttle looms, caltrop ceramic bombs, reinforced concrete... Though confined to a remote corner of the realm, he refuses to settle for a life of ease. He works tirelessly to govern well, taking one step at a time toward the throne.
