The basement of the construction site was pretty vast. There were iron bars, sacks of cement, large wooden crates, and other building materials kept in different places.
On the other side of the basement, there was a makeshift wooden door guarded by two burly figures in black cloaks.
Andrew, Bryan, and Elijah walked across the basement and came in front of the two burly figures.
Without exchanging any greetings, the burly figure on the left asked, "What has thirteen hearts but no other organs?"
"A deck of cards," Andrew answered without hesitation. At the same time, he brought his right hand forward and gestured a series of numbers with his fingers.
The burly figure was silent for a few moments. Then he stepped aside and gestured to the trio, "You may enter."
Andrew stepped forward and pushed the wooden door open, Bryan and Elijah followed behind him.
There was a short narrow passage after one entered through the door. The walls of the passage had gas lamps embedded in them.
