Modern Eco-Friendly Underground Bunker

Generate a hyper-realistic image of a modern, eco-friendly underground bunker with multiple levels, showcasing a seamless blend of sustainability and luxury. The top level features a small, wooden, above-ground structure with solar panels, surrounded by lush greenery and a serene landscape with rolling hills and a wind turbine in the distance. The underground levels reveal a spacious living area with a fireplace, a modern kitchen, bedrooms with en-suite bathrooms, a home gym, and a storage room stocked with supplies. The interior design emphasizes minimalism, with an emphasis on natural materials, ample lighting, and a neutral color palette. The image should capture the essence of a self-sustaining, off-grid retreat, with attention to detail on the materials, textures, and the interplay of natural and artificial lighting. The overall atmosphere should evoke a sense of tranquility, security, and harmony with nature.
