Actually, apart from the plaque system, Fang Ka also wants to adopt a real-world currency system.
This means creating physical Copper Coins, Silver Coins, and Gold Coins, so players can engage in physical transactions.
Because once the trading system opens, every time these players make a trade, they are submitting requests to the Soul Contract, and all these requests require Fang Ka to process.
This is a burden to his soul, although it's not a big burden, as someone who likes to slack off, naturally, if he can make things easier, he will.
However, at least for now, this island hasn't discovered any Copper Mines, nor Silver Mines or Gold Mines.
Therefore, at present, the real-world currency system isn't very reliable.
We can only wait until we interact with the outside world to see if this system can be implemented.
Moreover, tangible and tangible real-world currency will undoubtedly be more stimulating for players.
