Who is the soothsayer who bet with Jinghe Dragon King in the ninth Journey to the West? Is he a fairy?

Looks like this story is the tenth time, right? Yuan Shoucheng, Yuan Tiangang's uncle. Yuan Tiangang, a warlock during the Zhenguan period of the Tang Dynasty, was proficient in astronomical and geographical calculations, and folklore co-starred with Li in Tutui. None of them are immortals. Including Zhuge Liang in the Three Kingdoms Period and Liu Bowen in the late Yuan and early Ming Dynasties, are legendary demigods. But none of them are immortals.
