How do I translate 自己已经将地级上品功法无相神功...?
Have a look here. "无相神功" comes from a novel about an insuperable form of Kungfu. This is not very serious literature.

将 = 把
I set 无相 = formless, but maybe there are better translations.

自己已经将地级上品功法无相神功，
I already （将） [taught him 传授给了他] the earth-level best kungfu method "formless miracle" 
(无相神功 = a kind of kungfu, just a name, don't translate)"

以及无相步，
also the "formless step" = (a kind of kungfu, just a name, don't translate)

无相指和无相剑法 （go to 将）[传授给了他]，
the "formless finger" (just a name, don't translate)  and "formless sword" method"

不知道他如今修炼的如何？
don't know what his kungfu is like now.

不要打我哦！
