This is what Ravenclaw looks like..

Chapter 47 Aftermath
"It's good to be diligent and studious in Ravenclaw, but you are too diligent."

...

"Don't learn from those Hufflepuff students. Their daily habit is to eat in the kitchen."

...

"Mrs. Pince has a special elf in charge of meals, and she is not the only one on duty..."

"what?"

Andrew pretended to know what happened before and correct it immediately, but after the last sentence came out, he really couldn't pretend anymore.

"Of course, this is the library of Hogwarts, not Azkaban... Watching students for more than ten hours a day without weekends, working for a whole semester, do you think it's possible?"

This is indeed outrageous - even Professor Binns doesn't work this hard.

"But every time I come here, Madam Pince is there."

"Because there are two Madam Pinces, and they are twins."

???

Does this work too?
"As a qualified Ravenclaw, you should be able to understand this easily," Hand spread his hands. "Similarly, as a qualified sixth-year student, what I want to tell you is that food cannot be solved with magic. Even the closest thing to copying food is the Refilling Spell. The copied liquid only tastes similar. After the magic loses its effect, it will backfire slightly on the drinker."

"So, it is impossible for our librarian to stay in the library all day and not go to eat. This is common magic knowledge for senior grades."

"Very useful common sense, thank you." Andrew hesitated, but finally couldn't help but ask, "So, if I use magic to summon a bunch of food, and the magic is not canceled during the eating process, what will be the consequences?"

"For a wizard, he'll realize the problem quickly, and the spell will wear off quickly, leaving you even hungrier than before you ate."

"For wizards?"

"Of course," Hand said matter-of-factly, "If it's for Muggles, I advise you not to even think about it - that's a shortcut to Azkaban."

Azkaban is Rome, so we can go there after just discussing it?

But it is obviously not appropriate to discuss this with the crazy people in the society - for a group of people who are devoted to the Ministry of Magic, Azkaban is the greatest blasphemy, even if it is just an academic discussion.

"I'll ask Professor McGonagall later... and ask her about the idea that came to my mind when I was casting the spell just now."

Although he is not his own dean, as long as Professor McGonagall answers in this regard, he will be thick-skinned enough not to think about other issues.

He began to try to change the subject to something else, but before the two of them could return to the common room, the news that the alarm was lifted had spread throughout the castle - it was said that a group of Gryffindor guys had the guts to do it, but no one had come forward to admit it.

"Now that the alarm is clear, you can act on your own."

He was soon abandoned in disdain - after all, he was not from a small faction.

Andrew was also happy about this, but it was a pity that it was inconvenient to go out to mail a letter at this time. (The fact that a troll had entered the castle and he went to the owl shed was like the culprit had tipped off the matter. He was afraid that he would be pinned down by a group of prefects who were eager to make a contribution, and then he would be hanging on the astronomy tower counting stars today.)
-

The next day, Andrew, who was among the students, delivered a package of ordinary-looking manuscripts. After happily polluting the poor professor's knowledge base with his drawings once again, he happily went to Professor McGonagall's office.

"Please sit down. Have you gained any new experience in spellcasting?"

"Yes, Professor."

Andrew answered happily, "I even examined the performance of the senior grades." He couldn't deny that he didn't know about the troll, and since everyone said so, Andrew naturally took the blame happily.

“Although those guys seriously violated school rules, I have to say they did a good job.”

Professor McGonagall even had a hint of a smile on her face, but it quickly disappeared. "It looks like it was done by those third-year guys."

"The coordination wasn't smooth, but they made good use of the terrain," Andrew said calmly, as if it had nothing to do with him. "I'm far behind in this regard."

"It's not that they didn't work well together. It's that they underestimated the troll. They thought it was as docile as the ones in the magical creatures course. They were all in a mess whether it was controlling the traps or the subsequent Transfiguration. The spell attack in the middle didn't play the role it should have."

So much has been found out?

That is to say, I had a preconceived notion that it was a third-year student, otherwise it would be really hard to put the blame on him... Of course, the more important reason was that there were no casualties, and it was just a disobedient prank, so Professor McGonagall did not want to investigate further and deduct points from her own school.

"In fact, they can do better." Although she was too lazy to check, Professor McGonagall still graded the papers as if they were homework. "If the group is more cooperative, then one person can simply control an object to attract the troll's attention, and the others can take the opportunity to transform and reinforce the trap. In this way, basically no other means are needed to control the troll to death."

"If it's a senior wizard, it's actually easier."

Professor McGonagall paused and looked at Andrew.

"It temporarily animates the object - so that you can calmly use Transfiguration to set traps before the magic destroys it, without having to concentrate on controlling the object to attract the troll."

"That's right, so I'm definitely not a fifth-grade student who's tired of studying and wants to have some fun."

Just as Andrew was about to ask the next question, a snowy owl flew in through the window and dropped a letter on a nearby table that was already piled with letters.

"Oh, sorry, Professor, that's all. I'm sorry to bother you again."

"It's okay. I welcome talented students to explore Transfiguration more. If I didn't have to deal with those supply orders and the like, I would rather spend my time on teaching. Okay, continue to experiment with Transfiguration. Remember what I told you - don't get involved in theories you don't understand."

"Yes, Professor, I will keep that in mind."

"That's good. By the way, if you want to delve deeper into Transfiguration, I hope you have some knowledge of arithmetic divination. That will make it easier for you to understand the physical forms of plants and animals."

"Arithmetic divination? Is it to be sensitive to numbers? This way, you can understand the proportions of plants and animals more intuitively?"

"Okay, I do have some knowledge of Muggle arithmetic. I'll review that stuff as soon as possible."

"Well, great. I'll have to deal with the paperwork here."

+ + + +
"Yes, understanding the model of the object will definitely help the authenticity of Transfiguration - although magic blurs this relationship, it still has a certain impact."

"Besides, I was thinking about putting the letter on Dumbledore's desk and completely ignored Professor McGonagall..."

"As long as I simply understand the supply system within the school, I can easily forge a letter from the supplier to inform Professor McGonagall."

...

"My math is pretty good, and I've also built up a solid foundation in Transfiguration. Although my other subjects aren't that great, I haven't fallen behind too much..."

"If you have good digital processing skills, you can use the work-study method to help process documents in the office."
