Using a lantern to light up the path, the sword dancer led the night adventure group to the clock tower. Because I was already familiar with the procedures needed to enter the tower, I went forward and reached for the door knocker. After a second or two, a muffled groan could be heard from the other side, and the door started opening. The one who opened the door this time wasn't the Anchor's shop owner's grandson.
"As I said earlier, the city walls were neither hollow nor big enough to contain all the people who lived here, so the geniuses of the past designed the place in such a way that maximized space all while making sure the safety for the people who lived there was obliged." the sword dancer started explaining how the whole system works while I conversed with the door-pusher.
Alice, being a bundle of curiosity manifested, asked, "Isn't it hard to open that heavy door every time someone wants to enter?"
