行走的城市：巨型腿部与可移动的都市机体

Design a mobile city in the manner of Archigram as an enormous ovoid vessel bristling with antennae and telescopic gangways, standing on eight vast articulated legs that lift it above a ruined plain. Compose the riveted metal hull with rows of small round portholes, hydraulic legs planted at different extensions, retractable tubes reaching toward a second vessel in the distance, a flat empty landscape and low horizon, hazy graphic daylight, low view up the legs, 24mm lens, architectural photography, ultra photorealistic, 8K
