Can you recommend a fantasy magic novel with a master-disciple relationship, where the icy master and the female protagonist fall in love at first sight?

Dear reader, I recommend "My Hobby is Cultivation" to you. The relationship between the female protagonist and her master was very complicated. From master and disciple to lovers to legendary partners, her master was strong and cold. She had fallen in love with him the first time the female protagonist met him. Not only does this novel have magical elements, but it also has a sweet and warm master-disciple relationship. It really suits your needs. I hope you like my recommendation. Muah ~
