People across the street put a pile of cement in their corner, and a brick on the cement is facing my house.

Maybe it's feng shui charm. If you don't believe in yourself, go to the temple and ask for exorcism fees or feng shui mirrors. It is best to describe it clearly to the people in the temple and then put it in the corresponding position, so as to ensure the safety of the house and prevent suffocation at the same time. It may also be a pile of cement that they accidentally made when decorating. You can put the brick down to him to see if he will put it up again, and then you will know if it was put on purpose. Please adopt it.
