Apart from the training grounds and Barracks, Atticus also bought the Water Purification Station and Mess Hall.
They were both necessary. While some might think that Atticus should be more focused on defense currently, rather than growing and making his members stronger, Atticus didn't agree with that.
He felt that if worse came to worst – now that he knew he wasn't being graded – he alone could single-handedly protect the territory if those hordes of beasts came back.
It was better to organize his group first and foremost, plus, he had no plans of forsaking defense.
According to their descriptions, for the Mess Hall, as long as each individual pays a certain subsidized amount, they would be able to get a basic nutritional meal.
And the same was the same for the Water Purification Station. There was no need for operators or cooks; everything was automated.
