My friend just bought a second-hand house and went to see the house with my friend. As a result, my leg was cut. Is it evil?

You think too much. Not so mysterious. It's just that you are too careless and unfamiliar with the environment. It's not evil. The real evil is mainly the internal influence. Friend, you think too much. Give yourself a reason to scare yourself. If you are afraid, you can also read the name of Guanyin Bodhisattva. SouFun Chengdu second-hand houses only charge 0.5% commission for buying second-hand houses. I hope my answer can help you. good luck
