Yinghuo is a mermaid who lives in the Ying River. When she awoke, she owned nothing but a Fire Phoenix Jade clutched tightly in her left hand, carved with a phoenix reborn in sacred flames. To uncover the mystery of her origins, she traveled across mountains and rivers and through all six realms. To forget someone and cast aside their love, she chose the most resolute path of all: she split open the flames and burned herself alive. Only after being reborn did Yinghuo learn that the Fire Phoenix Jade did not depict a phoenix reborn in sacred flames. It depicted her: the ancestor of all birds, bathed in the flames of Lihuo and Lingguang, the spirit of the south, the Vermilion Bird. Only when the person she had desperately tried to forget spent his soul and flesh for her did she realize that the Fire Phoenix Jade was the very heart missing from his chest.
