Two: I just feel that I have made money. If we sell a mint, the system will reward us with the sales of 100 gold coins, and we can also get 10% of the daily production capacity of this mint! If someone keeps pushing behind you, you can take 10% of everyone behind you!
One-time investment, continuous income, no need to worry about anomalies, no need to stare at management, lazy mode! Trust my eyes.
