Ni Cang Tian
I know the feeling, like when you are standing on a ledge and a warm sensation spreads throughout your chest or when you put a knife to someone's throat and you are able to think calm and clearly, but that's only happened once for me and I did it without even thinking, well I did think that "I want this guy to shut up so lets shut him up" and then out came the knife , it was good that I did it, he never bothered me again and we were in a lot of the same classes too
