A dramatic, high-contrast digital painting suitable for an adventure thriller audiobook cover. The central image depicts a stylized, ancient Chinese dragon, rendered in deep emerald and gold, coiling around a partially submerged, weathered treasure chest that glows with an inner golden light. The background is a stormy, dark sea with turbulent, foamy waves crashing against jagged, dark rock formations partially visible in the mist. A hint of a distant, dimly lit, colossal ancient temple structure with traditional Chinese architectural elements can be seen through the fog on a cliff edge. The overall color palette is a rich mix of deep blues, stormy greys, emerald green, and glowing gold, conveying a sense of mystery, danger, and hidden riches. The composition is dynamic, with the dragon's movement creating a sense of action and the glowing chest drawing the viewer's eye. The mood is intense, mysterious, and epic. Square 1024x1024 format. Professional audiobook cover aesthetic. NO text, NO letters, NO words, NO title, NO author name.
