The miners under the coal kiln worked hard and suddenly a corner of the coal kiln collapsed one day and it turned out to be priceless Gemstone inside. There is a thick layer of rock around the Gemstone. If you want to get the precious Gemstone you need to dig up the outer rock layer. The miners are working hard.

Touch the Gemstone with your finger and keep rubbing and the friction will direct the miner to start mining. Because the rock layer is too thick and the progress of digging layer by layer is limited we can use props and use props to quickly dig through. And there are many places to get props so you can get more props quickly. Regardless of manual friction or use of props the ultimate goal is to get the Gemstone in the rock formation. Digging the rock formations will eventually get rich Gemstone rewards.
