Jack read the description of the new tech in the military path. This special tech appeared due to the blessing from the Blacksmith Circle.
"Mobile Fortress… Is this name literal…?" Jack asked.
John nodded.
Peniel explained, "After learning this tech, you can build one. A mobile fortress was slightly smaller than a small-sized fort. It can house around 20,000 soldiers, or 25,000 if they don't mind cramped conditions. What's special about this fortress is it can move."
"Uh, move like you mean, with legs…?" Jack asked.
John nodded again.
Peniel answered, "It is even faster than the average siege weapon. Its movement speed is roughly the speed of an uncommon steed. Most armies still have soldiers using common steeds, especially if it is a large army. So, marching with this mobile fortress won't slow down your army speed."
