The sword of the king's mines produce minerals for silver coins, while planting them on farms can bring you silver coins and Knights' fame. However, these two operations need to consume a certain amount of physical strength, the player had better make a comparison before operation and choose a more appropriate activity.
Minerals are also of high quality, but there is no need to dig too low-grade ores, which is a waste of energy. When you dig, if you brush low-grade mines, you can refresh them directly, otherwise it won't have much effect. I estimated that if you use all 240 points of physical strength in mining, you can get 350-500 silver coins, which means that as long as your income is in this range, it is normal. In terms of investment, it needs about 6 million gold coins. The silver coin income in mining is very fast, but there are many uncertain factors. We should pay attention to measure them.
The plants that can be planted in the game are wheat, corn, sorghum and grape. They need different inputs, and they also have great differences in maturity time and income. For example, wheat takes 1W and ripening time is 720 minutes. At last, you can gain 16 silver coins and 10 Knights' reputation, while planting sorghum with 998 red diamonds can bring 1000 silver coins and 3000 reputation.
There are three farms that players can plant. That is to say, you can plant in 9 plots. Here we suggest that you spend 10 blue diamonds to open another one. At present, for a total of 12 pieces of land, it is suggested that everyone should put their physical strength on planting grapes. Planting 12 grapes at a time requires 240W gold coins. The harvest time of grapes is 8 hours. If you plant them at night, you can harvest them when you get up early. After the harvest, plant the seeds. In the afternoon, you can harvest the silver coin fame again, and then you may get the advanced seeds.
