What was the first oriental fantasy book?

If it is not an ancient myth, it should be Huang Yi's Moon Magic published by Juxiange 1988. Anyway, it must be Huang Yi's.

Huang Yi's fantasy novels have formed a series, all featuring a character named Ling Duyu. Ling Duyu has a legendary experience. He grew up in Tibet, and then studied in the United States, where he got two doctorates. He also studied tantric Buddhism and had superhuman spiritual perception, so he was invited to explore many supernatural mysteries in the world.

Huang Yi's series of fantasy novels, each with100000 words, were printed into a small pocket book. Because fantasy novel in Huang Yi pays attention to suspense, twists and turns in stories and shows various strange metaphysical realms, his series became popular in Hong Kong and Taiwan after being published in fantasy novel. Huang Yi's fantasy novels claim to be "a combination of metaphysics, science and literature", but it is not clear how many scientific elements there are. However, metaphysics runs through the novel. Zhao Shanqi said, "Huang Yi is a master of metaphysics, proficient in geomantic numerology and astrology".
