Qioa yanze won't be that ruthless to kill cen xi... though he hates her sister bt his love for cen xi is more powrful nd it won't let himself or anybody do anything that would harm cen xi... I think it is that ji wei who would send the assasin to kill cen xi, she is literally a jealous woman, she knows that she would never make qioa yanze happy yet she is forcing everything on him nd she is destroying qioa yanze now... I just hope that cen xi is safe... Even if qioa yanze can't find cen xi right away i just hope he would realize that he only loved cen xi wholeheartedly nd would call off the wedding... As for cen xi nd qioa yanze's story, I guess with the line of author's point, there would be separation again for a short time (like we have separation in every single story)... I just hope things get resolved quickly....
