My friend said he was possessed and asked me to help him burn the villain.

Ha ha, psychological effect, you are too superstitious. The villain was a malicious curse in ancient times. Some people say that if you write the birthday of the person you want to curse on a villain made of straw, it will hurt to prick him with a needle. It can be scientifically proved that this is just a religious superstition, in order to relieve people's pressure. You tell him, you don't believe it, that's nothing, hahahahahahaha.
