The Thompson family of three easily found the street office for household registration at the Magic Capital Base according to the position displayed on the communicator. Perhaps because the base is still in a state of underpopulation, actually settling down turned out to be quite simple.
In fact, during the flood disaster, the Thompson family of three had already registered their household registration at Water Base No. 3 in Magic City. However, when the flood had subsided, a mysterious Natural Disaster destroyed all the data left in the water bases, and naturally, all information regarding the Thompson family's household registration vanished.
Of course, the Thompsons were not the only ones whose household registration was lost; when everyone's household registration had disappeared, it was natural that after the re-establishment of the base, it was necessary to re-register everyone's household registration.
