Imagine a sprawling underground city set far in the future, where technology and nature intertwine seamlessly. The cityscape is illuminated by bioluminescent plants and advanced, energy-efficient lighting, casting a soft glow on the intricate architecture carved into the earth itself. Buildings and structures, inspired by both futuristic designs and ancient cavern dwellings, spiral upwards, clinging to the walls of the vast subterranean space. The air is fresh, purified by advanced systems and the abundant greenery that thrives in engineered ecosystems throughout the city. Walkways and transport tubes connect different levels and districts, bustling with the movement of people and autonomous vehicles. Central to the city is a massive, artificial sun that simulates daylight, hanging from the ceiling and bathing the entire underground expanse in a warm, lifelike light. Around it, community hubs, markets, and recreational areas thrive, serving as gathering spaces for the city's diverse inhabitants. This underground metropolis is a testament to human ingenuity and resilience, a self-sufficient haven built for sustainability and protection from the harsh conditions of the surface world <lora:aesthetic:0.5> aesthetic <lora:sd_xl_dpo_lora_v1:0.5> <lora:great_lighting:0.5> great lighting, (masterpiece:1.2), best quality, (hyperdetailed, highest detailed:1.2), high resolution textures
