One of clan ancestors was a layman disciple of the Guanning's Thousand Light Temple, a branch of the grand Gold Sifting Sect. Feng Clan originally cultivated a Buddhist technique, but ever since the Thousand Light Temple moved away from the Liao Province several hundred years ago, they changed their cultivation art to a Confucian one. Due to his poor aptitude, the ancestor wasn't able to break through the barrier to Nascent Soul stage and form a Crystal Relic. As such, he was disheartened and established the Feng Clan of Ning instead.
The Kong, Zhang, Jin, and the Feng Clans were all neutral parties.
King Glorious Blaze plotted to gather cultivator souls to refine a Heavenly Corpse Body. The clan elders saw that something was amiss and wanted to inform a nearby Buddhist sect, but their Core Formation cultivators were exterminated. Then he manipulated clans to exterminate Feng Clan. Suddenly, the Kong Clan created an alliance with the two other clans and struck the Feng Clan off guard. As Feng Yue was a direct descendant of the Feng Clan, the Feng Clan Elders had him escape with the key as calamity befell the clan.
