Taoist fortune teller _ Who is the Taoist fortune teller?

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

Zhou Yixian's appearance is a fortune teller who seems to wander around all day, but Zhou Yixian's identity is still a mystery because Ding Xiao didn't write it clearly. Since Zhou Yixian can use the underground technique of Qingyun Gate, he must have something to do with Qingyun Gate, and he said that he accidentally fell off a cliff and saw what was recorded in Qingyun Book ... The correct rate of this conclusion should be very small, because what he finally knew seems to have surpassed some things recorded in that book. Zhou Yixian must have been from Qingyun Gate many years ago.
