That was a seriously bitch move.The dude did nothing but help her all series,helped with her cultivation,gave her a monster spirit suited for her,etc.All her current strenght is due to his help.And what she does?Says to his face that he is no better than Yu-han and that he just wants to marry her to get the City Lord position.The CITY LORD POSITION,something that he can easily become by his achievements alone,he doesn't need to marry her for that.
Sure,she did that for consideration towards Ning'Er,but that was still the worst possible way she could have done that.Even if she doesn't necessarily love him,she should have the minimum of respect for everything he did for her.
I really liked her character until this chapter,but now I just wish he dump her bitchy ass and stay with Ning'Er alone.
