Alchemy of Souls plot
In the land of Daeho, the noble Jang family rules. They are all magicians, except for Jang Uk. Magic that allows one to take over another's body is strictly prohibited. Nak-su, using the forbidden magic, is chased by other mages and jumps into Mu-deok's body to escape. She appears to be limp and blind. As Jang Uk's servant, she has to put up with many of his annoying demands. When he discovers who she is, Nak-su decides to help him change his non-magical destiny.
