When you are in a hurry to dig ore, I'll teach you the fastest way to wash it without spending much money, that is, buy all the ore and smelt it. If you compare it with the auction, you will find that the price of ore and smelting ingot is similar. You can buy ore for smelting, and then sell the ingots, which is almost equal to the free price increase. The tragedy is that the secret silver ingot will turn green as soon as it is smelted, and it takes more than N pieces of secret silver ore to rush to the color silver. Because the ingots can't be sold out at one time, I rushed to pick them, that is, they were full in half a day, and then a whole backpack of ingots slowly sold for 0.0. In fact, it is also money for you to dig your own mines, and it will waste your time and energy.
