This is what Ravenclaw looks like.

"So, Transfiguration is not about creating life. As the magic power is lost - oh, well, as the magic loses its effect, the transformed object will gradually return to its previous appearance."

"And those transformed creatures usually do not lose their lives. After the spell loses its effect, they will return to their original appearance, and everything attached will be rejected by the magic power..."

…

Professor McGonagall's analysis was so wonderful that Andrew, who had exchanged another 60 Galleons from Gringotts, could only follow mechanically, trying to remember every word, and almost completely ignored Diagon Alley, a small world composed of magic.

Professor McGonagall should be one of the top users of Transfiguration in the entire wizarding world. He dared to bet that there were definitely not many people who could easily figure out these random thoughts and answer them.

He could come to Diagon Alley by himself later, but he didn't know when he would get such an opportunity to concentrate on answering questions again - which vice-president would take so much time to answer questions for a student?

If it wasn't for the enrollment period, he wouldn't even think about it.

‘It’s a pity that I haven’t read the theory of Transfiguration in the magic world at all… As for having my own questions and opinions, forget it…’

‘Fortunately, when I mistakenly took the power of magic for telekinesis, I had an idea, otherwise it would be a shameful waste. ’

He thought so and did so.

“You said that you can feel the power of magic, and that power is still increasing?”

After listening to Andrew’s question, Professor McGonagall sorted out her words a little, “According to the existing magic theory, this is called the magic agitation period. The magic power of the little wizard will increase rapidly for a period of time after the first manifestation. At the same time, more and more magic phenomena will appear.”

“As for control, it is normal. Some traditional wizard families will even try to teach the dangerous magic powers they have mastered after the first magic agitation, but before the age of eleven, such behavior can easily lead to injury. I personally do not advocate this method, but there are indeed some traditional families who let their children master many lethal spells before school that wizards cannot control until graduation.”

“And casting without a wand is normal, but generally speaking, the power of magic is not , and with the help of the wand, wizards can use their magic more skillfully and accurately. At the beginning, due to the problems of proficiency and compatibility, it is not as good as casting spells directly through magic, but as time goes by, the advantages of wand casting will become more and more obvious. "

"In other words, the wand is a new weapon, and it may cut your hand at the beginning," Andrew nodded, understanding in his own way, "but as you become more and more proficient in the weapon, the damage will be far greater than bare hands?"

"The wand is not a weapon, Taylor," Professor McGonagall shook her head, "It is the best friend of wizards. You have to learn to feel the emotions of your wand so that you can cooperate with it, instead of simply using it as a tool. "

'This is very magical. In terms of Transfiguration, I have to get used to the influence of magic, instead of applying it with existing thinking.'

Andrew warned himself again-although he didn't know how long it would work, he insisted.

"I'll keep it in mind, Professor," he said, while raising a new question, "In wand casting, is the upper limit of the strength of a single spell increased by training or by the growth of magic power? Is there any way to increase magic power?"

"That's a good question, but we have to buy you textbooks first."

Such an answer made Andrew stunned for a moment, and then he noticed that they turned into an alley, and a shop that didn't get much sunlight had a crooked banner hanging at the door, with many letters leaning against each other and sleeping, and only the words "second-hand book purchase" (the word was half lying) could be recognized.

Considering the geographical location, the store should also sell second-hand books.

Of course, there are only second-hand books here-although in theory second-hand books can also be considered as highly profitable, the boss will never put the bookstore in a good location, and because of the long sales time, second-hand bookstores with long-term large inventory needs will not rent too good a location.

After briefly talking about the price, he bought some more basic books on the magic world recommended by Professor McGonagall as a condition, and got the textbooks and basic books he needed at a slightly cheaper price.

Although each of these things can be borrowed from the school library, it is still early before school starts - compared to laying a good foundation before school starts, this cost is affordable for him.

But money is already in danger, even if it is a second-hand book, professional books still have a very beautiful price.

Next are robes, scales, basic potion materials, brass telescopes and glass bottles and other sundries.

Andrew's questions basically did not stop. After thinking occasionally, a derivative question came up again, but no question could stump Professor McGonagall.

'It's incredible...'

While thinking and analyzing Professor McGonagall's answer, Andrew admired in his heart.

"Okay, enough questions."

When he was about to ask the next question, Professor McGonagall stopped answering, "I just told you that hair growth is the simplest of all wizard body transformations, so what do you think is the scope of this transformation expansion?"

"Hair volume, hairstyle, color, toughness, and hair quality."

After thinking for a while, Andrew quickly added, "If it is extended to other fields, it can be expanded to ropes, animal fur, the lushness of some plants... and... camouflage?"

"It is quite comprehensive. Although there are obvious mistakes, they are not mentioned, and it is very easy to make mistakes."

"Then what did I say about the introduction to Transfiguration?"

"The most basic Transfiguration is usually the partial transformation of dead objects. Generally speaking, it is the partial transformation of small stick-like objects into needles."

"What else?"

"Pay attention to spells, gestures, wand waving skills and firm beliefs."

"Almost correct."

After several questions, Andrew, who was preparing to answer the next question, found that Professor McGonagall had stopped. He was stunned and realized that they had stopped in front of a small and shabby store.

Corresponding to this shabby store is a sign with gold letters that are beginning to fall off, but the handwriting on the sign is not ordinary at all.

"Olivander: Making fine wands since 382 BC."

"Wand?"

Andrew was stunned for a moment before reading the unusual part of the sign.

"Yes, the wand," Professor McGonagall nodded with a smile on her face, "Okay, start your most important shopping and find your partner."
