"Your Highness, how tall and how wide do you plan to build this city wall?" Karl asked.
"At least five meters high, two meters wide, and allowing four people to march forward side by side." Roland subtlely acknowledged that Karl was indeed a professional, first asking about the technical data and then confirming the construction plan.
"Then a trench needs to be dug that's about one man's height in order to stabilize the upper portion of the city wall. Also, if the top of the wall is about two meters wide and the wall is about five meters tall, the width of the lower portion of the wall at least needs to be doubled," Karl promptly replied, "The process of trenching will need huge manpower. Your Highness, if you could provide me with 150 people, I could probably finish the trench before the Months of Demons."
"A gutterway could not possibly block the demonic beasts," Roland said noncommittally.
