**A sprawling, hyper-realistic 3D scene** depicting the **Lower World safe zone city from *Gachiakuta***. **In the foreground**, a fortified scrap-metal **wall** encircles the city – an immense ring of bolted junk plates and girders with jagged spikes along the top, embedded with giant vents and rusted pipes. The **main gate** stands open, fashioned from massive steel slabs and flanked by improvised watchtowers and barricades of debris. **Outside the wall**, the land is a toxic wasteland: mountains of trash, wrecked vehicles, and swirling smog under a dim, polluted sky. **Inside the wall**, a dense **post-apocalyptic shanty town** unfolds. A colossal **central air filter tower** rises in the distance, crowned with scaffold platforms and glowing lights piercing the haze. Around it huddle multi-level **ramshackle buildings** built from sheet metal, cracked concrete, and salvaged objects (old containers, broken machines), all stacked and squeezed together. Rickety ladders, staircases, and rope bridges crisscross
