Notes from a Strange Visit Around the World

My name is Lin Du, and I work in a job that is not easy to explain to others. To put it simply, it is to help people take care of "things". I am familiar with domestic matters, such as exorcising evil spirits, controlling houses, and destroying evil spirits. The methods passed down by my ancestors can be used in most situations. But some things don't work - some things are not in the ancestor's catalog. When he left, he left a message: "Out of this area, your methods may not be effective."
