Like all major cities within the Empire, Delray City boasts a vast and complex underground network system.
Although the city has been destroyed by war, the underground network remains mostly intact, with only a few areas suffering localized collapses due to artillery strikes.
Wang Chen walks through it, surrounded by darkness and emptiness.
The diameters of these underground passages are enormous; not only can he move freely as an individual, but even piloting a mecha poses little obstacle.
If this were the pre-war Delray City, the sewage system would have been full of wastewater flowing downstream to the treatment plant, but war destroyed everything, and the conduits have long dried up, leaving only foul-smelling garbage.
This garbage has bred large quantities of insects, as well as sewer-dwelling creatures like rats and cockroaches.
