Imagine a futuristic underwater metropolis. This submerged city is composed of glowing domes that are interconnected by transparent tunnels. Schools of engineered, bioluminescent fish swim past, casting a radiant glow in the deep ocean. The city is alive with activity, with bustling markets filled with floating products, cutting-edge laboratories where scientists study the ocean ecosystem, and residential areas providing homes with panoramic views of the ocean floor. The deep blue surrounding the city contrast with the bright lights of civilization, emphasising this utopian marvel of humanity's innovation.
