Professor McGonagall has been teaching at Hogwarts School of Witchcraft and Wizardry for thirty-five years, and she is arguably the oldest member of the faculty of the professors who are currently teaching besides Professor Binns.

Throughout her long teaching career, Professor McGonagall remained almost always dignified and stern.

This made almost all the teachers and students in the school feel awe of her—not the simple disgust and fear of Severus Snape, and more similar to the emotions that people have when facing Dumbledore.

After all, over time, many of the most successful people in the wizarding world today were former students of Professor McGonagall, such as Lucius Malfoy, Arthur Weasley, and Severus Snape......

Compared to the affable Professor Dumbledore, Professor McGonagall has her own way of doing things, and does not tolerate either brazenness or stupidity, and especially abhors any cheating and clever tricks - especially those who try to evade and misinterpret Transfiguration, which she values and loves most.

"I think I need a reasonable explanation, Miss Kaslana. ”

Professor McGonagall glanced at the snail on her fingertips, which had lifted the "Transfiguration Magic" and returned to its original form, and stabbed Elena with a sharp eye like a frost blade, and her voice was extremely serious.

"As far as I know, with your talent for magic, it's easy to master true Transfiguration without such tricks—instead of constantly deceiving people with meaningless illusions, as is the case now. ”

There is no doubt that Elena Kaslana is probably one of the most magically gifted witches Minerva McGonagall has ever seen over the years, whether it's potions, herbology, Charms, Transfiguration...... Even the boring and tedious history of magic and astronomy, she is like a natural wizard, and there are no shortcomings in any field at all.

For the past two months, Professor McGonagall has been thinking so.

It wasn't until this day, under Hannah Abbott's unintentional reminder, that she suddenly realized that it was likely that Elena had been using such illusion magic for so many days, deceiving everyone's eyes, and at the same time deceiving a lot of extra points.

Even now, she was amazed by Elena's magical abilities and imagination - creating illusions was not an easy task, and in a sense, it was even more sleepy than mere Transfiguration.

The long-term shame of being deceived, the grief of Elena's squandering of her talents, and the shock of the illusion magic that the girl had created herself in order to cope with the lesson...... It's hard to tell which emotion is overwhelming, but there's no doubt that "Elena's Cleverness" ends today.

"So Elena has been cheating?"

"I knew that...... How could it be possible to master it so quickly......"

"Do you think Professor McGonagall will deduct all the extra points?"

"If you think about it this way, maybe she will do the same for other classes. ”

"Well, we've been fooled by her all along......"

As Professor McGonagall and Elena spoke, the young wizards in the classroom gradually reacted, stopped their attempts at magic, looked over curiously, and whispered to each other.

Everyone's eyes were filled with excitement and inexplicable indignation, as if they had received an exhilarating gift.

I have to say that Elena's previous performance at Hogwarts was too eye-catching.

Rather than witnessing the continuation of a legend, most people are looking forward to seeing the bursting of a beautiful bubble or the embarrassment of a proud white swan falling from a height.

This has nothing to do with age, it has nothing to do with geography, this is the root of the bad root that is rooted in the depths of human nature.

This rare thing, similar to being caught cheating on a top student's exam, instantly ignited the interest of most of the little ones, although few people realized that the magic displayed by Elena may actually be more difficult than Transfiguration.

That's why Professor McGonagall's expression is so complicated......

If you want to use an analogy, it is roughly equivalent to a middle school math class, a student in order to avoid tedious calculations, directly write a set of mathematical software such as MATLAB, and then skip all the processes to get the results.

"It's not an illusion, it's Transfiguration. ”

Elena was silent for a few seconds, then looked up at Professor McGonagall amid the whispers of the surrounding students.

"In other words, the mainstream perception of transfiguration in the wizarding world is not fundamentally different from my magic. Professor McGonagall, you should be well aware of the Five Exceptions to Gamp's Basic Metamorphosis, so I don't think I'm doing anything wrong. Strictly speaking, what I'm showing is a variation of modern Transfiguration. ”

Although the girl knew very well that if she directly admitted her mistake at this time, it might just be over with a verbal punishment, but feeling the sudden schadenfreude eyes around her, Elena felt that she needed to justify it a little.

Whether it's to change the subject or to engage in a debate about the nature of Transfiguration.

At least...... Don't let this accident become the same conversation as a "holiday gift" for these students today.

Professor McGonagall easily saw Elena's intentions, but she didn't intend to fit the girl's script exactly - a genius who was always smooth sailing, and it was hard to guarantee that the future would not go astray.

Taking this opportunity, Minerva McGonagall intends to sharpen Elena's temperament a little.

However, before that, it is true that you have to take into account the emotions of the girls first, which is also the experience that Professor McGonagall summed up after a lot of things - Elena is a child who eats soft and does not eat hard, and especially cares about her own face.

"If I'm not mistaken, this is the second time you've spoken of the 'Five Exceptions to Gamp's Basic Law of Transfiguration'. ”

Glancing around at the whispering students, Professor McGonagall raised an eyebrow and said coldly.

"But that's what the seventh-grade Transfiguration course is about, Miss Kaslana. Unless you can fully explain this concept, I don't think it's necessary to discuss the nature of Transfiguration with you at this point - in other words, you first have to prove that you have the knowledge to study magic, not just magic. ”

With Professor McGonagall's voice, the discussion in the classroom instantly fell silent.

The content of the 7th grade course, the study of magic and the nature of magic...... The words weren't hard to understand, and from Professor McGonagall's tone, it was clear that there was something different from what everyone imagined to be simple cheating—if Elena could actually answer those questions, perhaps it would be more appropriate to describe it as a dispute of academic ideas.

Looking at the flickering eyes of the students around her, and then at Professor McGonagall, who had a bit of anticipation hidden in her eyes, Elena instantly understood what Professor McGonagall meant, nodded calmly, and replied unhurriedly.

"Of course there is no problem, since you think it is necessary, Professor. ”

"The 'Gamp's Basic Transfiguration' is a theory of magic proposed by the famous wizard Gamp hundreds of years ago after a long career of experimenting with magic. There are five major exceptions to the modern Transfiguration mentioned in it, which are magical situations where it is impossible to complete. ”

If Elena could only answer this question a few weeks ago with a few memories of her previous life, then after two months of study, she has completely made up for the shortcomings of this theory.

Even, after combining some of her own spell-casting experience, Elena has a further understanding and derivation on the basis of the theoretical explanations in the books, and Professor McGonagall also knows about this - as the only two Transfiguration masters at Hogwarts, Elena naturally asked her for advice in this regard.

Therefore, when Professor McGonagall asked this question, Elena's heart instantly relaxed.

The half-heightened hostility and tension dissipated as she smiled at Professor McGonagall.

"First of all, Transfiguration can't conjure food, whether it's a directly molded dish or an ingredient. This is also the most important point, which means that there are great limitations in the transformation of matter. For example, Professor McGonagall, the lions and pigs that you used to turn into a lectern in your first class cannot be used for cooking. ”

Elena paused, her gaze slowly swept over the faces of the group of little ones who were expecting to see the excitement, and the corners of her mouth raised.

"These days, I think everyone should know that the food on Hogwarts plates is not conjured out of thin air by magic. All dishes are cooked by the house-elves in the Hogwarts kitchens and then served on the plates above by the transfer magic. ”

"The second point, which happens to be what today's lesson is about - 'There can be no permanent deformation between living and dead things', we can only temporarily turn the snail into glass beads, but it is impossible to turn it into a lifeless dead thing forever, once the magic attached to the snail dissipates, it will automatically change back to its original form. In the same way, desks can't become pig ...... forever."

In fact, in the original Kamp Basic Law of Transfiguration, it was actually written that objects cannot be permanently transformed from one another.

But since Elena mastered a part of the magic between Transfiguration and Alchemy, this description of the law of hundreds of years ago seemed less rigorous to the girl's eyes, so she added a part of her own understanding here.

As long as she does not change the nature of matter and the composition of her elements, Elena is now able to easily change the shape of some small and simple objects as easily as she kneaded plasticine.

The only difficulty is that all of her transformations are permanent.

The wizarding world's regular disarming of Transfiguration does not unravel objects that Elena has unleashed on Recombination, which is why Elena has been reluctant to delve too deeply into Transfiguration - as Dumbledore said, one must be extremely cautious when dealing with any magic that cannot be reversed or reversed for the time being.

Glancing at Professor McGonagall, who was about to speak, Elena didn't choose to explain too much.

There were some things that only had to be told to Professor Dumbledore, and if Dumbledore thought that Minerva McGonagall could have known all this, the old wizard would have volunteered to tell McGonagall about this knowledge instead of choosing to seal it.

"Thirdly, Transfiguration can't conjure magic items. Whether it's a broomstick, a self-stirring cauldron, a wand, or even Gringotts' gold gallons and silver sico, they can't be transformed - they may be close in appearance, but when they are placed in a coin bag, they don't count automatically, they just become ordinary items with no magical powers. ”

Sitting on the largest mountain of gold in the entire wizarding world, Elena naturally carefully studied these coins in circulation in the wizarding world.

There is no doubt that the cunning and suspicious goblins will not forget about currency anti-counterfeiting.

All gold coins are infused with subtle magic, and the character number imprinted on the edge represents the information of the minter, as well as antioxidant, reinforced, and automatic counting functions - which is why the wizards' poor mathematical skills can use such a complicated and cumbersome currency base system, and the coins produced by Gringotts will perform some simple "change and calculation".

"Fourthly, Transfiguration cannot change the number of an object. For example, we can't turn a mirror into two snuff boxes, or a desk into two pigs, or seven people into a gourd. Unless you use the 'Integral Transfiguration', where all objects connected to an area are magically wrapped around and transformed. ”

Regarding this, Elena even made some more dangerous attempts.

When she got lost some time ago, she had the idea of treating the stone wall in front of her as a single entity, turning them into gravel, trying to temporarily open a straight passage to the distance.

Unfortunately, Hogwarts Castle seems to have been protected against magic in this area for a long time.

Any Transfiguration of the main body of the castle will default to the entire Hogwarts Castle area, and there is not much difference between trying to drill a hole with Transfiguration and turning the castle into a Transformer.

"As for the last point, although Mr. Gamble describes it in his book as 'Transfiguration cannot be made out of nothing' and relegates it to the exception to the last Transfiguration, it ......"

Elena raised an eyebrow, a look of nostalgia in her eyes.

"I'm more used to calling it the [equivalent exchange] principle - there is no gain without sacrifice, and what you want to get must pay the same price, which is also the most basic concept in ancient alchemy. It's like the summoning technique learned after the senior year, either the projection formed by magic or the use of the transfer charm, which is not directly conjuring objects out of thin air. ”

"So...... Am I qualified now? Professor McGonagall. ”

In the end, Elena tilted her head, and there was a hint of smugness on her delicate face.

"Based on the nature of modern Transfiguration, I don't think there's anything out of the ordinary in my approach, after all, the Transfiguration we're learning now is actually a relatively advanced illusion...... Are you satisfied with this explanation, Professor McGonagall?"

Looking around at the sudden realization on the faces of the other students in the classroom, as well as the admiring and adoring eyes, Elena pursed her lips rather speechlessly, these first-grade children are so easy to fool and have no position of their own.

However, from the beginning, she did not take these first-year students' comments to heart, she just wanted to take this opportunity to make Professor McGonagall understand that it was actually the ideal situation for everyone to not interfere with the river water as before.

What a little witch with a terrible talent.

Professor McGonagall gave Elena a deep look, filled with emotion.

There are many people with excellent magical talents, but there are only a few people in the wizarding world who have been able to try to dissect the nature of magic in the first place, and there have never been people in the wizarding world over the years, and those like Elena, who began to explore in the first grade, have never appeared in her memory.

"Overall, there really wasn't too much of a problem. Because of your brilliant answer, Hufflepuff adds five points. But ......"

Professor McGonagall paused slightly, frowned at Elena's smug appearance, and continued with a smirk.

That doesn't seem to be a reason why you didn't do what I asked in class to complete your classwork. ”

"Huh?!" Elena blinked, as if something wasn't quite right.

According to the script in her heart, this time should go to a happy ending for all, rather than some strange follow-up.

Professor McGonagall gently pushed her glasses, and a dangerous glow reflected from the edge of the lens.

"I'll make special adjustments to your course content after that – on the other hand, let's talk about the penalty for not turning in your homework for two months in a row. You may need to be reminded that as Head of Gryffindor House and Deputy Headmaster of Hogwarts, I have the right to punish you directly......"

"And the punishment for you is ......"
