Robot chiến đấu khổng lồ tại nhà máy lọc dầu

Cinematic photorealistic vertical shot of a gigantic humanoid female combat robot standing in the center of an industrial oil refinery under a dark overcast sky. The robot features a pale porcelain-white armored body with exposed black mechanical joints, cables, pistons, and intricate internal machinery between segmented plates. She has a slim feminine silhouette, broad armored chest, long legs, large mechanical feet, a serene doll-like face with red eyes, and shoulder-length [silver-gray] hair drifting gently in the wind. She holds exactly two weapons: a long conical spear-like blade in her left hand pointed downward toward the wet ground, and a long straight sword blade in her right hand angled downward and outward. Composition is a dramatic low-angle perspective emphasizing colossal scale, towering over the surroundings. The sprawling refinery features exactly five prominent distillation towers in the background, dense scaffolding, catwalks, pipes, tanks, and tiny helmeted human workers at ground level for scale. Wet asphalt ground with reflective puddles from recent rain, cool gray color grading, high-contrast metal textures, realistic lighting, and subtle atmospheric haze.
