Ore is mainly aimed at professional production skills, and the occupations with large demand are:

1, jewelry processing, this major needs a lot of minerals (not ingots), because all the gems needed for jewelry are fried by minerals (it's a waste of minerals, and five mines will probably fry 1 gem. But it is very useful), the higher the grade, the higher the ore grade corresponding to the gem.

2, forging, forging can be said to be a big mine, a lot of ore is melted into ingots and then made into equipment and then sold (very wasteful. . Silver scale breastplate is the product of forging), generally more than ten ingots can be used as 1 equipment.

3. engineering. Compared with the first two majors, this major uses much less ore, but it also needs to be smelted into ingots. Many interesting inventions are made by this major.

Extended data:

Most copper mines are produced in Katz Mo Dan and Locke Mo Dan, because these two places are convenient and mountainous. According to my experience, there is no place with more output than these two places. The copper consumption of mature servers mainly comes from fast engineers.

For example, 10, who plays the battlefield, has 8 people throwing bombs, which is more effective in Lan. As for forging, most people who practice basically learn to mine by themselves and won't buy it, while most engineering people don't learn to mine. Half of the students who have studied engineering are basically learning to watch others play, PK is practical and so on.

So it is very rare for them to give up one of their 300-year majors and ask them to give up both, so the market is still considerable.
