In this context, the Dwarf Kingdom has a surplus every year, but the overall surplus is not high; it's basically balanced trade.
Now the situation has changed, the original continental cyclical economic model has become an alliance internal circulation mode.
Unfortunately, the allies' productivity is limited, making it easy for them to bring money to the Dwarf Kingdom to buy buy buy, but making them export goods to balance trade deficits, that's difficult.
Demon Core and Magic Nucleus are strategic resources and cannot be exported in large quantities. What's left to sell are food and minerals, resulting in the Dwarf Kingdom accumulating a pile of ores.
The most troublesome aspect of bulk commodity trading is transportation.
The originally high-profit transactions consume profits during transportation, leading to a sharp decline in profits.
It's okay to earn a little less, but trying to offset the procurement of high-premium weapons with raw ores requires a considerable amount.
