It is not easy to flush, and novices don't recommend it. I almost graduated from equipment in the 1970s, and I have no money to fill in the project. At that time, the other was mining. Basic self-sufficiency If you spend money, it depends on the price of your clothes. I wonder if there are any low-grade minerals in the auction house? Very expensive. It is recommended to practice with mining. If the task is upgraded, it should not be much worse. Fill in one while mining. If it is not very expensive to make up the effect (longan stone for project FM jewelry), a big bracket is enough. 4000G should be enough. If you want to fill it up, prepare a sales card. I think I can sell a few copies. If it is an engineering OEM, you can still earn a little money now. Jewelry is basically 10-30G (that is, cutting a gem for others), but the money for learning drawings is very expensive, and it is even more expensive to learn all of them. In addition, materials are not needed to cut gems. Generally, I find friends and guilds to cut for free, and I can hardly earn anything.
