Feng Yan, the avatar of the Nine Heavens Divine Furnace, concealed his identity to protect Yun Zhi for a hundred years to repay the grace of incense offerings. He helped her build the Yunmiao Sect and set up the sect-protecting grand array, but was regarded as useless and expelled from the sect by Yun Zhi, whose cultivation reached success and was blinded by false fame. Feng Yan withdrew his array-eye body, and the grand array collapsed instantly. When the demon clan invaded, Yun Zhi suffered a complete defeat. Feng Yan established the imperial edict of peaceful coexistence between humans and demons, refined the devil-tempted Yun Zhi, and finally transformed into the Heavenly Dao to permanently protect the peace of both the human and demon races.
