Neon Lake in a Subterranean Cyberpunk Cave

Inside a vast subterranean cavern, a tranquil lake glows with neon cyberpunk light. The cave walls are lined with bioluminescent minerals and embedded circuitry that pulse in electric blue, pink, and emerald. Stalactites drip into the water as holographic advertisements and a distant neon cityscape ripple on the lake's surface. Drones skim the glassy water while a sleek electric boat glides among crystalline formations. Mist swirls through the air, rain threads from a crack in the ceiling, and the synthwave palette creates a moody, otherworldly atmosphere.
