"The leftover from back in the day." Changtian rarely joked, but his bared-teeth smile appeared doubly ferocious to the Chongming Bird, "If you're willing to serve as her mount, this feather will belong to you, and you can comprehend the ways of cultivation from it." As Bird Demons are on the brink of death, they condense all their essence, Qi-Blood, and life's experiences into a single Treasure Feather for the use of future generations. Generally speaking, the Treasure Feather of a Chongming Bird is hidden within the crest on top of its head, but this secret isn't known to outsiders.
