"Lunch time is coming, I think you can reluctantly put away your saliva that is about to flow out and focus on the classroom." Professor McGonagall stabbed Ferrey with his frost-black eyes. "Besides, even if you grab this deer and go to the barbecue now, it will not turn into a delicious plate of barbecue, because the "Five Exceptions of Gamp's Basic Rule of Transformation" mentioned that in the Transformation technique, "there is no permanent transformation between living and dead objects." So unless you like to eat charcoal, please take good care of the public property of the school!"

Verne found that Ferey was so scared that his face was pale. In order to prevent him from fainting, he could only speak out to divert Professor McGonagall's attention: "This... I'm sorry, I would like to ask the professor, what are the five exceptions to Gamp's basic law of deformation?"

Professor McGonagall easily saw Verne's true intention, but she did not blame her, but said coldly: "This is the seventh grade course content, Mr. Cadmond. Unless Mr. McFasti is willing to submit an additional paper to me, I don't want to talk about this to you at this moment."

Feray, who was blessed with his heart, instantly realized Professor McGonagall's true meaning, and immediately replied with a bitter face: "Thank you for your guidance, I am extremely happy to complete this paper."

"Hmph!" Professor McGonagall glared at the other lively people and slowly walked to the podium. "Since this is a seventh-grade course, I won't ask any questions. The "Five Exceptions to Gamp's Basic Rule of Transformation" is a major argument made by Gamp's famous wizard - Sercy Gamp after a long experimental career. It mentioned that there are five exceptions to transforming, which are impossible to achieve."

"First, for the boundary of food deformation, wizards cannot create delicious food out of thin air, nor can they turn other things into food. Even if you eat it, they cannot absorb nutrients, but will become indigestion. However, if you already have some food, you can transform it and make it bigger." Professor McGonagall glanced at everyone in the audience and said: "Food will appear in the plates in Hogwarts, not from it, but after cooking at home elves, they are transmitted to the utensils on the table through the 'moving spell'."

"The second point is what I just said, 'There cannot be permanently transformed between living things and dead things'. We can turn the button into a scarab, but it cannot move forever. As long as the attached magic power dissipates, it will still be restored to a button. In addition, the transformed scarab, even if it has the breath of life, is still a button. If you feed it to a bird, it will not fill its stomach, but will choke to death." Professor McGonagall said a cold joke.

"Third, deformation cannot transform magical items, such as automatic quills, variable temperature crucibles, etc., and even Jin Jialong. The currency circulating among our wizards is used by fairies. It will not oxidize, and it will not be easily destroyed. It also has the ability to automatically identify and count." Professor McGonagall cleared his throat, "Fourth, deformation cannot change the quantity, that is, you cannot turn a table into two deer, or turn three quills into a shovel, but it has an exception. If the connected objects become a 'whole', then the 'total deformation' can be used to change it, and even if it turns back, it will not affect the arrangement and attachment of the original object."

"That is, if I turned Mr. McFasti into a wild deer now and turned him back, his clothes would not stick to him like fur." ​​After that, Professor McGonagall glanced at Ferrey maliciously, and scared him so much that he hurriedly sat upright.

"Finally, and most importantly, 'transformation cannot be made out of nothing'. Maybe you have seen senior students use magic wands to create a group of birds or a bouquet of flowers, etc., but these are by no means transformed. Those things may be just 'limited-time physical projection' summoned by magic spells, or they are hidden in their palms." Seeing the students in the audience showing "so that's it", Professor McGonagall couldn't help but feel satisfied. The scene she loved to see most in her life was the way the students suddenly realized, which was also the main reason why she devoted herself to teaching. Finally, she pretended to curse: "Hurry up and take notes, do you think you can forget it if you can't take the fourth grade exam?"

After class, Feray squeezed his face miserably, thinking about what books to go to the library to check later, but saw Professor McGonagall walking towards him, and he stood still and dared not move at all.

"Mr. McFasti, you are not a mummy, why is your body stiffer like this?" Although Professor McGonagall frowned, his eyes looked at Ferrey with a smile. "I'm looking for Mr. Cadmond, do you want to hear it too?"

"No, no, of course not!" After Fei Lei hurriedly packed his schoolbag, he ran away as if he was amnesty.

"Mr. Cadmond, am I really that scary?" Professor McGonagall looked at Ferrey's figure leaving in a mess and asked with emotion. Although he had obvious answers, Verne could only respond with a dry laugh.

Seeing this, Professor McGonagall could only shake his head helplessly and said, "After the afternoon class, Dumbledore will come to you, and the command is 'honey syrup'." After speaking, she looked at Verne for a moment and said, "Finally, I want to congratulate you, Mr. Cadmond, this is a good opportunity, you must seize it."

Verne knew that this congratulation was for him to be Nico.

When Lemay took him as an apprentice, he immediately bowed humbly and said, "Thank you for your kindness, professor."

At dusk in the afternoon and sunset, the lake next to the castle was covered with a layer of brilliant gold yarn, swaying with the rippling waves, like a girl's skirt immersed in the breeze.

In front of the principal's office of Hogwarts, a gargoyle stood alone and looked at the window. The whole atmosphere became somewhat lonely. After Verne issued the command, he patted the gargoyle on the shoulder and then stepped on the rotating ladder. In front of the oak door, he caught the brass door ring in the shape of a lion-shaped eagle and buckled it three times, and then the door opened automatically.

But when Verne stepped into it, he was surprised to find that Dumbledore was not here until a portrait of the principal on the wall explained: "Dunmbledore went out for a while for a while. He said he would come back soon, so please stay for a while. He also said that if you are bored, you can go to the bookcase on the right to read the book. In addition... the chocolate candy is also hidden in its lowest layer." In the portrait, the female principal with long silver curly hair blinked, "The last sentence is revealed to you specifically, go and eat it with your heart!"

"I will report to Dumbledore according to fact, Daliss, you are teaching a child to steal food from others without permission." The portrait of a wizard with a goatee and a slender eyebrows cursed.

"Oh, Phineas, you always lack a sense of humor..." Dalis sighed, plucking her curly hair.

Listening to the bickering of the two paintings, Verne chuckled, bowed slightly, and walked to the right side of the room, preparing to pick up some books he was interested in to take. In front of the teak bookcase, he was about to choose, but was surprised to find that there were only seven or eight books on the cabinet shelf, especially most of which were like novels, as if some were from wizards and some from Muggles.

"I should have guessed that Professor Dumbledore asked me to read books, and the purpose would never be simple..." Verne smiled bitterly in his heart, and randomly pulled out a thin book called "Crime and Punishment" from the shelf and started reading it.

From the preface, Verne learned that "Crime and Punishment" is a novel written by the Russian writer Dostoevsky, and the book in his hand is just a simple and popular version. As he read it more and more, Verne gradually became immersed in the lines. Because of his spiritual advantage as a wizard, he read it very quickly and finished the book in just over twenty minutes.

The article roughly describes a poor college student, Raskolnikov. He is kind-hearted and helpful. He was originally studying in the law department. In the end, he was forced to drop out of school because he could not afford the tuition fee. He even did not pay the rent for a long time. In response, the landlord's wife not only stopped providing him with food, but also urged him to rent very tightly.

Later, he met a young civil servant, Malmeradov. He unfortunately lost his job recently, and his eldest daughter Sonya was forced to be a street prostitute. This sounded the alarm for Raskolnikov. In addition, some of the social reality and utilitarianism that he had seen before made him think that he could never be slaughtered like the other party, so he finally decided to use a method to "prove" his extraordinaryness, that is...

kill!
