White-Robed Swordsman with Long Sword in High-Speed Dash AI Image Prompt

16:9 ultra-wide horizontal composition, high-end Eastern wuxia concept painting, a fusion of Chinese ink wash, impasto oil painting, silk texture, and dry-brush strokes. The background is almost entirely deep black, ink black, and extremely deep cyan-black, forming a huge black negative space. An adult East Asian swordsman is positioned about one-third from the left side of the frame, the figure appearing relatively small. He wears a loose wuxia robe in gray-white, ivory white, and off-white. His body leans clearly forward, caught in a moment of high-speed forward rush and sliding step. His head is slightly lowered, not looking at the camera, with a cold, stern expression. His black hair is tied high, with loose strands flying backward. He holds an extremely long Eastern longsword with both hands; the blade is slender and straight, silver-white and cool gray, extending from his hands almost horizontally toward the right side of the frame, becoming the clearest sharp horizontal line in the image. Most importantly, the huge white robe hem: the lower part of his robe, cloak, and skirt are dragged at high speed toward the right side of the frame, forming one huge continuous white flowing structure, like white silk, water flow, or an ink-wash brushstroke stretched out in a single stroke. Near the figure, real fabric folds are retained; farther to the right, it gradually turns into silk-like streamline, dry ink-brush drag marks, a translucent white liquid feel, a slight water-mist feel, and smooth brush trailing marks. The interior colors of the robe hem are ivory white, gray-white, pearl white, light gray, and a small amount of warm off-white, with local impasto, local flying-white, and local exposed black ground; at the right side of the frame, the ends gradually break into white ink threads, water marks, mist threads, and flying particles. At the very bottom of the image there is only a very narrow gray-white horizontal ground or white brushstroke; the figure appears to skim at high speed over a white canvas, and the end of the robe hem blends naturally with the ground. The lighting is low-key with cinematic high contrast; the main light comes from the upper left or upper right side, the white robe is the main illuminated area, the face receives only a small amount of light, and the black hair almost merges with the background.
