Secondly, all gold mines previously owned by the Kashi Family will belong to the Cangqiong Family. The reason Xin Yun didn't covet this aspect was that even if he had the gold mines, he couldn't manage them and lacked the energy to organize people to mine them. Therefore, it was better to let the Cangqiong Family take care of everything.
Although the amount of gold produced each year is significant, at least a million people are needed to keep the entire gold industry chain running, including protecting, maintaining, mining, transporting, smelting, and so on. The Sky-opening Sect simply couldn't do this. Moreover... with the banking scheme in place, Xin Yun didn't care how much gold was mined; it would all end up in his hands anyway. So why bother doing it himself?
Earth People all know that as the banking scheme develops, in the later stages... all the gold will be taken by the banks, and what will circulate instead will be paper-printed Coins.
