Andy has the same opinion about dark magic as the author of that book.
Dark magic is indeed evil, but we can't ignore the advantages of dark magic just because it is evil.
If white magic is the study of external matters, then dark magic is the study of the human body itself.
Perhaps this is the main reason why the system distinguishes dark magic from charms.
The reason why the dark magic Disease Infestation was recorded in the book by that author was because this magic involved magic's erosion of the human body.
The author argued that although wizards could use magic, wizards themselves were not magical creatures, and were very different from those magical creatures who were born with the ability to use magic.
Andy agrees with this point of view.
Because wizards must utilize wands to cast spells, this is the best proof of this point of view.
The reason why wizards could achieve their current position in the wizarding world was because humans are intelligent beings, while magical creatures are not.
The author of that book raised an interesting point, if a wizard spent day in and day out eroding his body with magic, would he turn into a magical creature over time?
Of course, Andy wasn't going to make that attempt.
Because the author of that book had already died because of it.
The last few chapters of the book were written by the author on his bed in St Mungo's Hospital for Magical Maladies and Injuries, and he died after writing it.
The book was then donated to Hogwarts.
But this idea certainly reminded Andy.
Andy had seen pictures of Voldemort online, and while he was still superficially human, he was completely inhuman.
Scarlet eyes, pale skin, no hair on his head, and two narrow nostrils that looked like a socket.
'Maybe Voldemort did some dangerous magical experiments on himself as well.' Andy thought so.
Then what about Dumbledore?
Maybe Dumbledore had secrets of his own.
"Incendio!"
After a fire burned the weed, Andy straightened his clothes and went back to Honeyduke's Candy Shop first, and then returned to Hogwarts through the secret passage.
Walking out of the secret passage, Andy looked around.
"Luckily, no one is here!"
Andy first went to the Owlery and sent the candy he bought to Isabel, and then went all the way to the abandoned classroom on the fifth floor of the castle.
Pushing open the door, he saw Hermione practising magic all alone.
"You scared me!"
Hermione blankly glanced at Andy without any good sense, "You don't know how to knock on the door first when you come in, I thought it was the professor who came in."
Andy couldn't help but complain, "What kind of image does the professor have in your mind? If they saw you practising magic hard here, won't they be happy in their hearts?"
The little witch pondered at his words, what Andy said was also true, she hadn't done anything bad, so why was she so afraid of the professor?
Glancing at Andy, the young witch suddenly realized.
She hadn't done anything bad, and she was still practising magic hard. But practising magic with Andy always felt like she was doing something bad.
Andy just doesn't know how to peek into the mind, or else he would be complaining that he was wrongly accused, how can I be held responsible for this?
I came to Hogwarts for nearly a week, what bad things have I done?
"What the bloody hell have you done now?" Hermione asked.
"Didn't I say it, you'll know in a few days, anyway, it's a good thing." Andy continued to play dumb.
"If you don't say it, don't say it!" Hermione grunted.
Not bothering Andy anymore, the little witch practised magic on her own.
It was still early to dinner time, Andy didn't want to waste time either, so he practised magic as well.
The book he had read before had written quite a few refreshing theories of magic, Andy was ready to experiment with them.
The author of the book did not start with emotions but expounded on magic from the magic itself.
What is the nature of magic?
No one in the magical world could be sure.
As Professor Flitwick said, magic is like the blood flowing in our veins, it is inside us, but it is difficult for us to control it.
However, strenuous exercise can accelerate blood circulation.
We have no way to directly control the magic, but we have a way to passively influence it.
Andy practised magic according to the methods written in the book.
When he initially tried it, Andy realized that his spell casting became very unsmooth, the feeling was like a person who was used to writing with his right hand suddenly trying to write with his left hand.
Awkward!
Andy did not stop but kept trying over and over again. After practising for a dozen times in a row, a slight annoyance arose in Andy's mind.
According to the book, annoyance in the mind was a normal phenomenon.
Andy decided to trust the book!
And then...
Boom!!!
There was an explosion that not only startled Hermione, but even Andy was a bit dumbfounded.
"I failed to cast a spell?"
Andy hastily tried casting a normal spell, but unexpectedly realized that his spell casting seemed to have become much smoother.
The feeling was so subtle that it was as if it was Andy's illusion.
Andy hurriedly tried again.
It was not an illusion!
This feeling was as if someone had been holding it in for hours and suddenly let out a stream of water.
To describe it in a word, refreshing!
"Are...are you alright?" Hermione looked at Andy with a worried face, a kind of look as if Andy had finally gone crazy.
"I'm fine, don't worry."
Andy calmed down and pondered in his mind the principle of this change.
In fact, to put it bluntly, it was still the emotion that was affecting the magic power.
When Andy continuously attempted that kind of unsmooth spell casting and became more and more annoyed in his heart, the spell casting would naturally fail.
This sense of annoyance was actually a kind of emotion, and when this kind of emotion reached a certain critical point, it would naturally affect the magic power in the body.
'Worthy of being an author who experiments and plays himself to death.'
Andy found that the books written by wizards who died from failed magical experiments tended to have somewhat genuine stuff.
On the contrary, those authors who had lived to the end of their lives, or who had not died yet, usually followed the same scripts as other books, and at most, they only added a little bit of their own understanding based on what their predecessors had written.
'So... the next focus is to find books written by wizards who died from magical experiments?'
'Or maybe find a chance to go to St Mungo's Hospital for Magical Maladies and Injuries and talk to the patients about magic?'
Were they really just crazy people with a wide range of ideas?
Andy thought he might be crazy.
But the truth is, only those wizards who dare to try can truly realize their magical theories.
Whether they succeeded or failed, if they dared to try, it meant that there was more or less some factual basis for that theory.
What they lacked was perhaps a laboratory or a platform for communication.
Looking only from the perspective of researching magic, today's magical world was indeed a little too stable (lazy).
The establishment of the Ministry of Magic had indeed effectively managed the magical world, but it had also plunged the wizards into unnecessary trivial matters, as well as frequent power struggles.
It's killing the future of magic!
