What's the name of the person who learns fortune telling from the old man?

Who is the real identity of the fortune teller in Zhu Xian?

Zhou Yixian lives by telling fortune.

A man who wanders around all day but looks like a sage like type.

Zhou Yixian's identity is still a mystery, because Ding Xiao didn't write it clearly.

Since Zhou Yixian can use the underground escape of Qingyun Gate.

He must have something to do with Qingyun Gate.

And he himself said that he accidentally fell off the cliff and saw the book of Qingyun.

These are the things recorded above .. The correct rate of this conclusion should be very small.

Because the last thing he knows seems to have surpassed some things recorded in that book.

Presumably, Zhou Yixian was a member of Qingyun Gate many years ago.
