Worries are even simpler!
The resources needed for the next upgrade of these buildings are not only absurdly abundant, but also require silver mines.
The problem is, Great Xia still doesn't know what a silver mine looks like!
Xia Hong shook his head slightly, casting his gaze on the final Black Soil Wall.
100 wood, 20 iron can be exchanged for one meter.
All 50,000 meters exchanged would mean 5 million wood, 1 million iron.
[Resource: Wood 2 million Coal 2.76 million Iron 1.2 million Silver 0 Gold 0]
It turns out to be impossible to exchange all at once.
Looking at the remaining resources in the system, Xia Hong shook his head slightly.
The Black Soil Wall's defense capabilities are strong; before Xia Hong leaves the camp, it must be exchanged, fortunately only lacking wood, the problem shouldn't be too big.
