The Netherworld Butterfly Enchantress

She is the daughter of one of the four great families, naturally beautiful and possessed of a bewitching charm. She is also the leader of the Lingyan Pavilion, a cold-blooded assassin with a shapeshifting ability. When transformed, she becomes the Nether Butterfly Enchantress, who kills without blinking. But everything changes when she meets him. To stay together with him forever, she makes a decision: she will rid herself of her own mutation.

He is a handsome, aloof man from one of the four great families, always wearing a cold expression. But after meeting her, he changes. Though she leads the Lingyan Pavilion and possesses an uncanny ability, he loves her, deeply and irreversibly.
