Create a realistic black-and-white coloring page that depicts a cityscape with buildings and houses. Underneath the city, show a network of thick fiber optic cables running through the ground, with individual cables branching off and connecting to each house or building above. The city should have various buildings, including residential houses, to symbolize connectivity reaching each individual structure. The underground cables should be detailed, with lines and patterns that represent fiber optics. The composition should use clean, consistent lines to create a clear, detailed, and structured illustration, highlighting how underground cables connect the city with internet access. --ar 99:70
