提示词 prompt：如下：

Cinematic photorealistic texture, pure ancient Chinese Xianxia aesthetics, restrained deadpan comedy performance, observational cinematography, realistic micro-expressions, body weight, silk material, fine film grain, volumetric air depth, real 3D camera displacement, and a reference world that lives continuously from the first frame to the last. Control Protocol—three tracks must run simultaneously, but the three must never compete for narrative authority. The protagonist plot track has 100% screenwriting power. The environment life track has continuous motion rights but 0% screenwriting power. The background character track has independent life rights but 0% protagonist interaction rights. The environment must not create, trigger, explain, interrupt, solve, change, emphasize, or time any character plot. Wind, clouds, mist, light, reflections, architecture, distant characters, vegetation, and water bodies must not produce special reactions due to dialogue, eye contact, comedy bits, or protagonist actions. Why the camera moves is only determined by the protagonist's plot and character scheduling. But meanwhile: All non-protagonist areas must never be frozen. Understand all reference images as world DNA, not frozen pixels or static backgrounds. Before generation, understand geomorphic logic, architecture, scale, materials, weather, cloud systems, vegetation, reflections, movement lines, light directions, and spatial extensions to reconstruct a real 3D location. Maintain identity but allow spatial rearrangement. Throughout the 10s, every 2s window needs visible non-protagonist motion sources across layers. Motions cannot start simultaneously or move at identical speeds. Extreme Background: Huge cloud layers migrating slowly and steadily. Deep Mid-ground: 4-6 small independent extras (walking, using stairs, tidying clothes, passing each other) with zero connection or reaction to protagonists. Mid-ground Air Layer: Mist and low clouds bypassing structures with realistic occlusion and spatial logic. Foreground Layer: Consistent elements (mist, plants, banners) briefly passing close to the lens to establish spatial presence. Reflective surfaces change with camera angles. All motion shares a unified weather system. Character A: Elder sister, 25-30, East Asian female, oval face, dark almond eyes, long black hair with white jade hairpin, tall/slender, white embroidered silk Hanfu. Character B: Little sister, 20-25, East Asian female, round/agile face, braided black hair, petite, cyan linen Hanfu. 0-5s Plot: Camera dollys forward/sideways. Protagonists walk. Elder sister says seriously: 'Today we practice concentration. Whoever laughs first, loses.' Little sister stops all expression. They face each other. Plot is active, background is independent. 5-10s Plot: Face to face. Little sister puffs one cheek slightly for 0.5s. Elder sister raises an eyebrow slightly. Elder sister's lips tremble imperceptibly. Camera arcs 15-20 degrees with real parallax. Comedy comes from micro-expressions. Ending state: 9.5-10s, characters stable but world continues moving (clouds, walking extras) to serve as a bridge for Part 2. 16:9, Mandarin dialogue, restrained score, realistic foley. Negative (Part 1): blurry, bad quality, etc. Part 2: Generated as an extended video inheriting identical characters, world state, motion phases, and suppressed laughter from the end of Part 1. 10-15s Plot: Little sister mimic's the elder sister's cold expression. Elder sister's nostrils flare slightly. Both try not to react to the other's face. 14.5s: Both break character with a short, real laugh. Environment remains independent and non-reactive to the laughter. 15-20s Wrap-up: Briefly laughing, then regaining seriousness. 'Draw?' 'Again.' They turn and continue walking. They exchange a final look with a hint of a smile. Camera follows with a lateral track. Final 0.5s: They walk forward while the background world remains fully alive and moving. Negative (Part 2): blurry, bad quality, background resets, frozen extras, synchronized environmental reactions, etc.
