A massive futuristic underground Minecraft base beneath a modern 5-story quartz mansion. The base is built in a large circular layout around a central glass elevator shaft, extending deep underground with multiple stacked levels. Each level is connected by spiral staircases and features detailed interiors including living spaces, farms, storage rooms, and advanced work areas. Several levels include large glass biome domes (jungle, desert, and greenery). At the bottom is a glowing lava-powered energy core surrounded by water and lighting. The design is symmetrical, clean, and highly detailed, using quartz, glass, and modern lighting to create a high-tech underground city.
