The scarce substance of coal, on the one hand, is because we cannot dig directly, on the other hand, it is mainly a kind of thing of association. Only when we mining can we find the thing of coal.

And not all ores will be accompanied by mines. This thing has many requirements for the temperature conditions and other factors. Only when we mine in places bordering barren deserts and mountains will we increase the chance of finding coal. And we should not dig with our hands with our heads in their hands. For example, things with magic bonuses will be more efficient when digging. For example, our tool-type material ceiling - a crystal pick can make us dig faster, and the explosion rate of our colleagues will be relatively higher.

It should be noted that what can produce coal is not the black ore we think, but the kind of things like large blocks of soil will be easier to produce. After we smashed it with a pickaxe, we will find that the large block of soil will gradually crack. After it cracked to a certain level, we can see the interface prompting us that there is something to pick up, and these things are the coal we need.

For example, in the early stage, most of the things we use can be made directly with drawings, but after we are forty, we have to make them ourselves, and the existence of this furnace must be in handy. After smelting, coal can become an exquisite coal resource, and this coal resource will eventually become a helping us in making equipment. As long as we are equipped and any baby we want, as long as we can use equipment to press the blood line on the opposite side to a certain value within a certain period of time, and then put on tools, it is all right.
