Chapter 320 Progress is going well
"...In other words, the closer you are to the soul, the more cautious you must be when casting spells, and the brain is the carrier of the soul..."

Andrew read through the information and couldn't help but ask questions.

"I have never seen such a description of any other Transfiguration-related spell, Professor."

Is the brain the carrier of the soul?

It sounds like it makes sense, but the word "soul" is rarely mentioned even in books in the restricted area.

"Of course not. When it comes to things like the soul, the research process is the slowest because it's too dangerous," Professor McGonagall said in a serious tone. "If you're not careful, you'll become a complete idiot and won't even be able to become a ghost."

"But," Andrew was still a little puzzled, "but the reason why the damage caused by black magic is difficult to recover is that the soul has been damaged, this..."

“Not reasonable, right?”

"That's the way it is, Professor."

"There really is no logical explanation, but the brain is undoubtedly the area that causes the most damage to the soul, so until now, wizards have rarely performed transfiguration on hair and eyes."

So this is the reason why baldness and myopia in the wizarding world cannot be cured?

This makes sense, because the fear of causing permanent damage similar to black magic makes it dare not develop nearby spells, resulting in the worst treatment for these two parts.

Even Professor McGonagall wore glasses - this even affected the professor's Animagus transformation, because the students in the front row of Transfiguration basically thought that the cat created by the professor had square glasses-like patterns.

"I think I kind of get it."

"Remember, even if you become proficient in magic in the future, do not try to deform the surrounding area, especially the eyes. You can move the hair a little, after all, it is not difficult, but if you are not careful, you may go blind - even the most advanced magic eyes can still not be well matched to wizards."

"Yeah, I'll remember that."

Andrew nodded heavily, indicating that he would remember it.

"Well, continue, next paragraph, today's content is not over yet."

Different from the previous free-range comprehension training, the content of Human Transfiguration basically required him to ask questions about what he didn't understand after reading a few paragraphs, and then the professor would give a complete answer.

This attitude alone was enough to make Andrew cautious, so even though he had basically mastered the basics in the past few days, he still hadn't started practicing spells.

But the professor was already very satisfied with the progress, and repeatedly reminded him not to be anxious, but to take it step by step and understand all the contents thoroughly before casting the spell.

And in the midst of this training, he finally got approval.

"Bring that container of Sarcoma Powder tomorrow, and do your Boggart training while you're at it."

On the tenth day of study, Andrew read through all the content and got such approval from the professor.

"Yes, Professor!"

-

The next morning, when Andrew arrived at Professor McGonagall's office, the professor's office had been expanded to about the width of a classroom, and on the newly expanded ground, a tightly tied box was placed there.

"Don't be in a hurry to look over there, Taylor, let's practice Transfiguration first."

The professor even prepared an empty desk for him alone.

"Here, be careful. Although that thing is safe, it still has some aggressive tendencies in order to increase the user's attention."

The professor looked at the small snuff bottle and said, "It's a very convenient thing, but it's too expensive and the effect is not very good."

"It's mainly a little ugly."

Andrew gave his evaluation honestly, and the originally serious professor was a little amused.

"This kind of ugliness cannot be purchased with Galleons. Extend your left hand."

Andrew agreed and stretched out his left hand - and then was bitten hard by the damn box. "Hiss..."

He took a deep breath, and then watched his hands begin to deform wildly - this was the effect of the sarcoma powder.

Unlike the last time he was bitten, after understanding the basics of human body deformation, he began to feel the effect of the tumor powder on the not-too-serious deformation of his left hand.

This reversible transformation on himself allowed him to clearly sense the chaos and reshaping of magic - and this is exactly the power that human body transformation seeks.

"Like a glove, but the appearance is still not very good."

Andrew held up his left hand and made this comment.

He extended his wand and tapped his left hand - the ugly crust faded away quickly, as if nothing had happened.

"Nice recovery, Taylor."

The professor nodded. "It's a good tool to get started, isn't it?"

"Without a doubt, Professor."

Andrew stretched out his left hand again - it bit him again, and then his left hand began to deform again.

But unlike last time, the speed of the hard shell gathering this time slowed down visibly.

Andrew felt his control over magic and the chaotic power - and after about a minute, he removed the protection.

This time only half of the hand was deformed, and the hard shell didn't even extend to the thumb.

"Interesting, but still wrong..."

Andrew didn't act in a hurry. He looked at his left hand, then cast a spell on only one finger, slowly dissolving the deformation.

Then there was a long period of thinking and stagnation.

'It's probably this level of chaos. In other words, the most basic malicious transformation is related to this. In fact, it relies on the power of spells to disrupt the magic control, and even uses the victim's own magic to complete complex human transformation?'

'Interesting, interesting.'

He simulated it one last time in his mind, then reached out and let Snuffbox give him a hard smack.

"hiss…"

The pain made him forget to resist for a moment, and his hands began to deform rapidly. However, as he shook his arms, those hard shells began to be shaken off like water droplets on his hands, and finally disappeared.

“It hurts…”

Andrew looked at the snuff box unkindly - this thing bit too hard.

"This is progress beyond my expectations," the professor said with a delighted look on his face. "You've gotten started faster than I thought. The Black family's wealth is truly unmatched anywhere else."

"It's really valuable. Even Galleons can't buy such a clever thing." Andrew shook his hands. "It's just that, hiss... it hurts too much."

"Pain is a necessary warning, so that those who are learning it will not forget how dangerous it is. This is a benefit."

The professor shrugged it off, "One more time, make sure you can defend yourself against this chaos the first time you're attacked, Taylor."

"The dangers of human transfiguration must be kept in mind."

"Yes, Professor."

Andrew responded seriously, but this time he used his right hand - if he gave it to me a few more times with his left hand, he wouldn't be able to eat with his left hand today...
