Ling Xue was originally the unpopular second lady of the Duke of Ling. She was disliked by her mother and ignored by her sisters, brothers and elders. She could have been left to die, but by chance, she gained the attention of the fourth prince, and was gradually included in the prince's territory. She became the prince's right-hand man in the fight for the crown prince, and finally climbed to the top of the mountain.
