Underground City Treasure Chest in Anime Style

An ornate treasure chest rests on a carved stone pedestal in an underground city. The cavern is lit by bioluminescent fungi and hanging lanterns, with ancient arches and neon-lit rails along the tunnel walls, blending archaic stonework with futuristic glow. In anime style with crisp cel shading, vibrant colors, and dynamic lighting. The chest is gold, richly decorated with emerald inlays and glowing runic sigils on its lid, exuding a soft magical aura. Surroundings include dripping water, mist, and distant caverns that resemble a subterranean metropolis. Perspective is a dramatic low-angle shot focusing on the chest, the underground city receding into the background. Mood: adventurous and mysterious, with dust motes and sparkling particles floating around the chest. Optional tiny explorer silhouette in the foreground for scale.
