The Emperor's Favor - the Ghost Doctor's Wife

One year ago, the famous ghost doctor Ming Su'er was expelled from the sect for seducing the demon sect and killing his master's wife, and has disappeared from the world since then. A year later, she changed her name and came to Beijing. She originally wanted to "change her mind and start a new life." However, there was another big gold case that was making waves in the world. For the sake of her former master's century-old peace, she had no choice but to marry herself to Nangong Chen, the third prince in charge of the case, and become a little spy and a little great man to resolve this martial arts catastrophe. She saved his life three years ago. He fell in love with her like crazy and never stopped missing her in the past three years. But how could he have thought that the "unreasonable, cruel and child-abusing" princess he married... Was actually the same person as her?
