Immortal Cultivation, Untainted by the Mortal World

[A little angst, but nothing too painful; several couples, no dull moments; happy ending] Qi Nanxing, the eldest legitimate princess of the Ji Yuan Kingdom, was born with spiritual energy throughout her body. By the age of three, she could freely use spiritual arts without even cultivating. Born to nobility, breathtakingly beautiful, and favored by the ruler as the next heir to the throne, this exalted young woman is forced to marry Lu Ci'an, an ugly little beggar. It lights a huge fire beneath Qi Nanxing's already bad temper. She throws tea on him, kicks him, and humiliates and belittles him in every way, yet the little beggar doesn't get angry in the slightest. Lu Ci'an has eyes only for her, and just as he finally wins Qi Nanxing's attention through sheer effort, he accidentally reveals his identity as a member of the demon clan. Lu Ci'an dies at Qi Nanxing's hands. When he returns, will he finally get what he wants...?
