Playing PVP more is the project. If you play PVE more, it is jewelry. Because although the project of PVE has been modified, the benefits are not great. You can mine first, upgrade the project, then dig without washing, continue to dig low-grade mines, dig 5- 10 groups for each mine, and then exchange precious stones for mines, which is basically enough and won't cost you much. In other words, engineering, FM, jewelry refining, basically all bought materials, you make me feel embarrassed. .
