After the Imperial Court disappeared, some Holy Lands also issued similar currency within their own territories. However, since Spirit Stones can be directly used by cultivators, they inherently have value, whereas the issued currency needs to be backed by the authority of the Holy Lands.
Even during the time when the Human Emperor of the Eastern Emperor Court ruled the world, there were those unafraid of privately minting coins, let alone in the Holy Lands.
Everything becomes vulnerable to determined individuals, even if the currency is engraved with anti-counterfeit restrictions unique to the Holy Land. Under the temptation of huge profits, there will be individuals within the Holy Land who sell these restrictions, or they are deciphered by array masters and artifact refiners. Consequently, counterfeit currency spreads widely.
To maintain their currency, the Holy Lands have to exchange even counterfeit currency.
