黎明前，玄武岩峡谷里留一条蓝色河流

A broad basalt canyon before dawn. Near hexagonal black columns frame a faintly glowing turquoise river; natural rock arches span the distance, fine mist separates cliff layers and one warm star remains in the violet sky. Game-engine-quality physical materials, wide cinematic composition with breathing room at center. No creatures, text or logos.

黎明前的广阔玄武岩峡谷，近处六角形黑色石柱框住一条微亮青蓝河流，远处天然岩拱跨过峡谷，薄雾分出多层山壁，紫色天空剩一颗暖星。游戏引擎级物理材质渲染，宽画幅、中心留视觉呼吸，不要生物、字或标志。
