I'm afraid witches are really useful. What else can I do?

Don't be afraid. If what the witch did really worked, he wouldn't threaten you like that. In the news, you can see that many wizard masters said something ambiguous, but in the end, they were all sent to prison. If the practice is really effective, there will be no dynasty change in ancient times, and don't forget that a so-called wizard predicted Malaysia Airlines Flight 370 when it disappeared. That's a national wizard. As a result, Malaysia Airlines 370 has not been found so far. If you are really afraid, you can ask a Buddha statue to take with you and ask for the blessing of Buddha and Bodhisattva.
