Four major challenges, the first three, according to Xia Hong, are manageable.
Such a massive wooden house requires an enormous amount of Golden Frost Trees;
Mu Dong knows the basic mortise and tenon structures, and it's certain that a batch of different iron tools needs to be crafted to assist;
Due to the size of the wooden house and the distinction of so many functions, supplementing key parts with a certain amount of iron materials is necessary.
"The hardest part is driving ground stakes, right?"
"At a height of fifteen meters, the structure uses whole Golden Frost Wood, and the digging depth of ground stakes must be at least two meters. Calculating from a side length of two hundred meters, you'll need to dig a total trench of eight hundred meters long, three meters wide, and two meters deep."
Upon hearing Mu Dong's answer, Xia Hong felt a little faint.
