Two characters are engaged in a fierce exchange of punches and kicks. At the points of physical contact, there are instant sparks, explosion smoke, and flying dust special effects. These special effects flash by with each strike and do not persist. The camera gradually zooms out to reveal a broader fighting scene. Ensure that only these two characters in the picture are in continuous motion, with their movements being fast and powerful. The background is a dynamic outdoor or indoor environment with moderate lighting, highlighting the characters' movements. There are natural elements or scene props around, and the changes in light and shadow enhance the atmosphere. The special effects are synchronized with the strikes to enhance the impact and dynamism of the scene.
