I'm using Google Translate, so please forgive any language mistakes.

If I understand right, you're asking how to unlock the 30,000 gold achievement. If that is so, then the way to do it is by collecting a total of 30,000 gold. It is a total of all of the gold you get, so you have to keep on farming the levels.

我正在使用谷歌翻译，所以请原谅任何语言错误。

如果我没理解错的话，你是问如何解锁30000金币成就。 如果是这样的话，那么方法就是一共收集三万金币。 这是您所赚取的所有金币的总和，因此您必须继续耕种水平。

改成就了，好评
