OEM? That's a low-level means ... although it's easy to make money, you should remember that this kind of thing doesn't need any license. There are many people engaged in it, all of whom are small buyers. They cut 1 2 gems and are still bargaining. Almost all of them are asking gay friends for help. To really become bigger and stronger, please find a stable supplier, such as miners, and those who train trumpet and buy ore and install green (CTM). Valuable green gems were transformed into alchemy. Others make necklace rings, blue and green, sapphires can be cut well, enchantments can only be made into scrolls, top weapons enchantments such as landslides are absolutely easy to sell, and baby lanterns can be smuggled to the other camp to sell more money. And you can look at the price of your crystal, and then look at the price of the fire cloak. It is the beginning of mass production, and this egg-painful version is at the end.
