Seeing him down on his luck, she directly sends him into a pleasure house to act as a stepping stone for her task.

Along the way of lifting the curse, his proud avatar acts harsh and dismissive yet follows her closely with red ears, while his black-bellied true body presses closer step by step from the shadows. Ling Xi glares at him coldly, "Didn't you hate me to the bone? Now you can't bear for me to die?"
