Hey everyone! I've been binging on sci-fi and dystopian novels lately, and my mind is buzzing with a fun idea - designing an underground city! Now, the kicker is it needs to be believable enough that you can almost imagine someone stumbling upon it in real life. So, I'm looking for your help! Let's dive into the details of this hidden marvel: its purpose, power source, security measures, and even its unusual quirks. The more abstract and imaginative, the better! Who knows? Maybe we could turn this into a short story or comic concept someday. What do you think? Let's share our ideas, discuss the pros and cons of each, and together, build an underground metropolis that would leave people speechless! Looking forward to your creative inputs. :)

Hey there! If we're talking crazy yet plausible ideas for an underground city, how about this? Imagine a self-sustaining city powered entirely by geothermal energy, leveraging teh Earth's natural heat to generate electricity. It could house around 10k people with an area of 10 sq km (just over 3.86 sq miles). The city would have its own food production system using hydroponics and vertical farming for maximum efficiency. Water recycling and filtration systems would ensure a constant clean water supply. With advanced security, this hidden metropolis would keep its secrets locked underground!
