I might just stab someone

" A knife…why?" Second husband Sun was simply stumped when he heard that Yu Dong was asking for a knife and that too with a candle, what was she going to do with these two things? As a mer, he was very scared of things that will cause pain or draw blood which was why he was immediately startled when he heard Yu Dong ask for something so dangerous. 

Yu Dong knew that second husband Sun was hesitating because of her abrupt and weird request which was why she patiently explained the matter to Second husband Sun, " Second husband Sun, the reason I am asking for a knife and candle is simple. As you can see, the wound on Sun Jie's daddy has festered and some places have rotten which is why I need to cut these parts out or else he will die even if I was to hand him medicine, without removing the rotten flesh there will be no changes in the condition of Sun Jie's daddy."
