Underground Bunker Discovery

A single atmospheric comic panel of two explorers holding flashlights as they push open a rusted vault door in an abandoned underground bunker, revealing rows of dusty machinery bathed in beams of light. Detailed cross-hatched inking, cool teal shadows with warm flashlight glow, floating dust motes. A caption box reads 'Nobody had opened this door in forty years.' Suspenseful discovery mood, dramatic depth, cinematic mystery.

一格富有氛围的漫画，两名探险者举着手电推开废弃地下掩体里一扇锈蚀的金库门，露出被光束照亮的一排排积尘机械。精细交叉排线勾勒，冷青阴影配暖调手电光晕，漂浮的尘埃颗粒。一个标题框写着「四十年来没人打开过这扇门。」悬疑发现的氛围，戏剧化纵深，电影感神秘。
