Elderly martial arts master dissolving into sand in dojo

An elderly martial arts master training inside a traditional Japanese dojo, dynamic action shot. The master is morphing into sand, with particles of sand exploding and trailing from his hands and feet, sketching glowing, fluid paths of dust and grains in the air from his high-speed movements. Wooden floors, shoji screen walls, shafts of cinematic volumetric light cutting through the dust, dramatic shadows. Hyper-realistic, motion blur on the sand trails, Unreal Engine 5 render, 8k resolution, photorealistic, cinematic lighting, shutter speed 1/1000 --ar 16:9 --v 6.0
