Thank you for the correction but I don't understand these numbers. How does 1,000,000 gold per day turn into 5K per year?
1,000,000 are mined by the the king.
Mining is done each day.
Yes, the way it was written it could have been ambiguous without seeing the example of how it is done in the game, it is fairly plain once you see how it has worked in operation.
English is a sometimes tricky language.
