Return to the most hard-core "information acquisition and transmission" itself. Goldfinger is not a universal translator or portable space, but a geek-style intelligence warfare based on "physical mechanics + semiotics + micro-carving technology". The protagonist promotes the plot by dismantling Japanese military equipment, transforming machinery, and deciphering encrypted information carried by mechanical structures. He combines the "craftsman's craftsmanship" with the grand narrative of "resisting Japan and saving the nation", and completes seemingly impossible espionage missions through extremely precise operations in a hail of bullets.
