A sword cleaves a mechanical warhorse, and a defective AI awakens. Deadly missions come one after another: Tang Mai trades antibiotics for a black-market map and stops radiation from reaching the Eastern Han by sending the seismoscope its frequency. A steam train crushes the Embroidered Uniform Guard, and oracle-bone script is engraved on flintlock barrels. Errors turn into killing moves: “Jasmine Flower” disrupts an alien ring, counting rods solve quantum mechanics, and Qin citizens fold spaceships from chocolate wrappers. A mysterious figure leaves the words, “Error is a new beginning.” An LED display reveals the mothership’s coordinates, a bracelet shows a spiral pattern, and beneath the gear-moon, Lin Yuan leads the team in a roar: “Don’t destroy the gears. Let civilization grow freely!”
