She is the good-for-nothing legitimate daughter whose engagement was broken off, but she once awakened the bloodline of the ancient divine phoenix; he is the cold and arrogant demon king, who bears the blood feud of annihilating his clan. Destinies were intertwined in a blood moon catastrophe. She burned all the insults with the fire of Nirvana, and he used ten thousand bones as steps to break the destiny. When love blossoms on the blade, the two join hands to change their fate and take control of the world together - but if saving the common people requires his soul to die, she would rather destroy the world than live up to the king's heart.
