It seemed unlikely that anything could be found from the temporary base Justus had set up.
The double-layered structure that looked like a round cake or a crown, he had also seen in the coal-ash wasteland over a decade later.
It was called a "据点房." A very popular architectural form in the Underground City.
The first floor featured a reception and a lounge, with the latter opening seven doors, leading directly to the kitchen, a storage room that took up two rooms, a power room, and four living quarters. Climbing the circular stairs to either side, the second floor had eight more rooms, totaling twelve residences.
In a wilderness where it was unclear whether a city should be built or if anyone would come, such types of bases were usually the first to be established.
