古籍藏匿数据芯片（手部特写动作）

Cinematic thriller style, tight and tense atmosphere. Subject: a pair of black-gloved hands working over an ancient, leather-bound book; a small metallic data chip the size of a fingernail. Action: the gloved hand carefully slices open the spine of the book with a scalpel; the hand then delicately extracts the tiny metallic data chip hidden within the binding; the body tenses, listening. Camera: extreme close-up macro on the hands and scalpel, very shallow depth of field, slow drift-in. Lighting: single warm desk-lamp pool from frame-right, deep shadows around the edges. Environment: dimly lit private study, dust motes drifting, blurred shelves of leather books in the background. Audio: the soft crisp slice of the scalpel through old leather, dry paper crinkle, the metallic click of the chip lifting free, distant clock ticking, a sudden creak of a floorboard down the hall causing the hands to freeze.
