全景正视角拍摄，山岩洞穴内部改造的地下科幻工业设施通道，左侧墙面为斑驳的浅灰色水泥材质，墙面排布着多根深色工业金属管线、深灰色电气控制箱与方形密封金属盖板，靠墙摆放一张厚重的实木工作台，台面上放置黑色线缆卷、金属工具、小型方盒箱体，工作台旁的地面上放置一个打开的旧实木箱，箱内装有零散五金零件；通道地面为拼接式深灰色金属工业地坪，地坪上分布多处长方形嵌入式金属盖板与格栅缝隙；画面右侧是架高的旧木质栈道，栈道边缘安装黑色圆管金属护栏，栈道下方可见下层沟道与管线；通道尽头正中央是厚重的暗炭灰色金属防爆密封门，门体带有六边形分块造型与居中圆形机械结构，门体两侧内嵌绿色指示灯与小型操作面板；背景为凹凸粗糙的深灰色天然岩壁，岩壁上布有横向深色金属工业管道，岩壁顶部缝隙中生长着少量垂落的绿色藤蔓与蕨类植物，柔和的自然日光从岩壁顶部的缝隙斜向射入室内，在地面与墙面上投下清晰的条状光影，整体色调偏冷灰棕，材质质感写实，工业厚重感强烈，无多余人物与动态元素。

Full frontal perspective view of an underground sci-fi industrial facility corridor renovated inside a mountain rock cave. The left wall is made of mottled light gray concrete, lined with multiple dark industrial metal pipes, dark gray electrical control boxes, and square sealed metal access panels. A heavy solid wood workbench is placed against the wall, holding coiled black cables, metal tools, and small square boxes on its surface, with an open old solid wood box next to the workbench on the ground, filled with scattered hardware parts. The corridor floor is made of spliced dark gray metal industrial flooring, embedded with multiple rectangular recessed metal covers and grille gaps. On the right side of the frame is an elevated old wooden boardwalk, edged with black round-tube metal guardrails, with lower trenches and pipes visible beneath the boardwalk. At the exact center of the far end of the corridor is a heavy dark charcoal gray explosion-proof metal sealed door, with hexagonal panel divisions and a central circular mechanical structure, with embedded green indicator lights and small operation panels on both sides of the door. The background is a rough, uneven dark gray natural rock wall, with horizontal dark industrial metal pipes running along it, and a small amount of hanging green vines and ferns growing in the gaps at the top of the rock wall. Soft natural daylight slants in through gaps at the top of the rock wall, casting sharp strip-shaped shadows on the floor and walls. The overall color tone is cool gray-brown, with realistic material texture, strong industrial heavy feel, no extra characters or dynamic elements.
