Wrong Way to Open the Patronus Charm

It's also mentioned in the book, but I'll just mention it in the introduction. Diehard fans of "Harry Potter" should stop clicking. I'm afraid you'll be angry when you read what I write. This world is not similar to the original work. If you want to see an authentic Harry Potter, you will feel uncomfortable. Magic, spiritual power, or curse power are all one thing in this book, different energy systems developed on the same basis, just like everyone is a carbon-based creature, and some become humans and can use weapons, while some become beasts and can only claw and bite. What has been mentioned so far are the Western magic world (including Europe, America, India, etc.), The Chinese cultivation world, the Chinese extraordinary cultivation world, and the Japanese Onmyoji. I want to write a book of my own, so why start with a fan? This is because I am too lazy.
