武侠对决：白衣 vs 黑衣（三分镜）

Eastern Wuxia-style duel between a grandmaster in white and a grandmaster in black on an ancient stone platform. Shot 1 (0-5s): both clash at high speed, leaving afterimages; sparks and a ring-shaped shockwave erupt; the flagstone cracks, debris flies. Shot 2 (5-10s): they soar into the air, striking amid falling boulders and shattered pillars, with dust and air distortion emphasizing destructive force. Shot 3 (10-15s): both release ultimate moves, cyan and red energy orbs collide, triggering an earth-shattering explosion. Light: stormy overcast, hard rim from cracked sun beams. Camera: stable cinematic with controlled push-ins on the strikes, no whip pans. Style: photoreal Wuxia cinematic, anamorphic, epic score feel. Audio: thunder roll, blade clash, explosion bass. Constraints: maintain both characters, no watermark, no text, no extra limbs, no twins.
