If Lew Qingyi were to take on the mining, she would still be an outsider and would have to invest a substantial sum.
Compared to calling the shots in Luocheng, this was an unknown realm, and while it's one thing to have so much gold in a mine, it's another to profit from extraction, indeed a piece of meat, but not an easy one to bite into.
Wouldn't it be better for Lew Qingyi to do something else?
Resources don't mean everything, why aren't resource-rich countries necessarily powerful nations?
So, the foundation of a family is not propped up by these riches.
The family's industries are not just about being turned into money; on the global stage, they possess great power, a little-known secret is that these domestic magnates already have the power to impose sanctions on some small countries to the extent of causing destitution among their citizens.
They just choose not to; it is these powers that matter, not something that can be measured in numbers.
