The so-called "Wan Yan," is a mythical beast unique to Yun Meng Da Ze, according to legend.
Previously, at the Jianghan Academy in Wuchang, Mr. Lin from Wenjin Academy helped them translate the "Mountain and Sea Spiritual Response Scripture," and did not ask for any payment, but only made a request for their help in finding this beast.
Mr. Lin's second son was innately intellectually disabled, and it was rumored that the flesh and blood of this beast could treat him, hence he traveled extensively throughout Hubei, looking for clues.
Unfortunately, he found nothing.
Mr. Lin was extraordinarily knowledgeable and amiable, and both Lv San and Li Yan deeply respected him, so they agreed to his request.
Mr. Lin had handed over all the relevant materials to them.
In Sima Xiangru's "Zixu Fu," it was mentioned, "Below them are the White Tiger, Xuan Leopard, Wan Yan, and Hu An."
Guo Pu had annotated, "Wan Yan, a large beast similar to a palm civet, one hundred zhang long."
