What does carrying a sword mean in fortune telling?

This is a professional term for fortune telling, which refers to the official evil spirit and needs to be resolved. Being an official means that you will suffer a big loss in your official position, or even a catastrophe. So if you are an official, you should pay attention. However, in ancient times, this statement was to persuade people to do more good deeds. Now fortune tellers don't talk about it, which is too feudal and superstitious. Now fortune-telling only talks about health and weakness. I'd rather have this than that.
