Preliminary calculations put its copper reserves at 11 million tons, while its associated gold reserves exceeded 800 tons.
As for gold, there was no need to fear that an abundance of it would cause depreciation. As high technology developed, gold consumption in technological products would only continue to rise. Many industrial products required gold, so no amount of production would ever truly be enough.
However, Jiang Yan Hai and the others were still using steel-cased ammunition for the moment. Steel-cased rounds were plentiful, after all, so they might as well use them up first. As for switching the troops over to copper-cased ammunition later, they would first complete the replacement in the real world.
They arrived at the plaza below. Commander Lin hesitated before asking, "Aren't you afraid the Taotie will attack now?"
