Decompose the silver ore to obtain the material for improving jewelry.
National service version:
The same is true after 300. Decompose magical iron ore or gold concentrate. Which is the cheapest and best gold concentrate to play with, because the probability of gem production is high, you probably need 1 group. Of course, if small gems are cheap, buy them directly.
After 350, buy blue rolls+multi-gem rolls, all the way to 375. This stage is the stage of making money.
Other service versions:
300-320
Buy about 20 diamonds, and the processing will rise to 320. Probably just a few gold.
32 1-350 decomposes magic iron ore or gold concentrate. Which is cheaper to play?
Buy cobalt ore < 350-390
After 39 1, it's simple, processing sapphires and making money while practicing. Until 450.
