Touring the Warehouse

After completing the basic structure of the underground building, the machines started printing the walls, however, this time they were joined by a new batch of similar machines as they helped in the construction of the building much faster. But, the batch of these new machines wasn't all there for the construction of the walls. Instead, some of them went to the massive square holes that were left by the previous machines while they were printing the rest of the building, each of these holes was more than twenty meters in length from all sides and had a number of over fifty.
