I think it is a Chinese proverb, badly translated into English.

We have:
xuan fairy
YunHua
XuanXian
LingYan
ZhangShuai
As characters.
There are various mentions to "disciple" leading me to believe that it is the rambling story of someone old and knowledgeable with followers. Maybe a leader of an order? "the practice of mbt unono" There is also a secret weapon of sorts. "paralysis ring" "magic weapon"

I am led to believe that the story teller was on a number of drugs at the time due to the incoherent strings of speech. "you hear a lot of face"

Then at the end, we hear "Dan medicine." This could be the item that is advertised but we can't know for sure.

As for the site advertised, I did a google search on the piece of text we have. And found it in a blog.

I noticed that links were found on "mbt XXXXX"
So I searched for Mbt unono and found:

Not bad eh?
