The Four Symbols Sanctums' residence in the Punishment Zone of the Four Symbols Sanctums' First Mine had numerous cultivating residences. Just like each Sanctum of the Four Symbols Sanctums, they were divided into Primus houses, Secundus houses, Tertius houses, and Quartus houses that were placed in a pyramid formation.
Due to the reason there were not many Four Symbols Sanctums' disciples in the Punishment Zone, there were not many residences as well. For example, there were ten Primus houses in each Sanctum, but there was only one Primus House here.
In the Punishment Zone of the Four Symbols Sanctums' First Mine, there were only ten Secundus houses and a hundred Tertius houses. They had slightly more Quartus houses here. There were 2,000 Quartus houses.
