Fu Lingyun, the noble lady of the Dingnan Hou Mansion, was betrothed to Duke An Guo, who was both civil and military, but she was subjected to many plots. Fu Lingyun faced the turbulent Hou Mansion. The stepmother Xiao Lin tried to let her biological daughter Fu Ranyun marry into a wealthy family instead, but Fu Lingyun treated her the same way: Fu Ranyun was first disfigured, and then his reputation was ruined. Fu Lingyun got rid of the poisonous hands arranged by the Xiao Lin family in one fell swoop, and secretly cultivated her own power; she used the poison of the dripping Guanyin to make Xiao Lin's snake-scorpion heart known to the world, and exposed the intricate relationships behind it in one fell swoop, making it impossible for her to stand up in the Hou Mansion. Just when the hidden secret of the house was about to be revealed, Fu Lingyun was inevitably poisoned and his life was in danger.
