Visualize a sprawling underwater city that combines the beauty of natural oceanic formations with futuristic architecture. Picture buildings made from iridescent materials that reflect the surrounding marine life, with pathways lined by gently glowing sea plants. The city is bathed in a calm, soothing light, with large bubbles floating through the air and the occasional whale or dolphin passing by, adding to the tranquil, dreamlike ambiance
