"Yeah, so how exactly did they pull this off?"
"I heard it's because Hope Village came up with its own building materials."
"Cement?"
"Yeah, yeah, that's it. Right now only Hope Village has this kind of building material. The city walls of Hope Village, plus those new buildings, they're all made with this new type of material. Buildings made with this stuff are super sturdy—just as good as those buildings protected by Magic Arrays."
"Can they sell these buildings?"
"Nope, for now Hope Village only uses it for themselves. But I heard a few territories seem to have made a deal, you have to provide shells if you want to buy cement from Hope Village."
"Shells? You can use shells to make cement? Hope Village just told everyone their raw material like that?"
"Yep! They never really hid that at all."
