Elena seemed to have had a long dream.

She dreamed that she had entered Hogwarts, where old potatoes, old turnips, big bats, and big cats lived......

Yes, she became a real witch.

With a colorful study career, she also met cute little iron girls and little beavers. And in the distance, there is a young little moon waiting anxiously for her reply.

But now it's time to wake up......

Today's lesson seems to be the one she never understood, "Quasi-Conformal Mapping and Teichmuller Space".

The professor is a foreign teacher from Russia, but he is quite fluent in Chinese, with a slightly distinctive tongue accent, and is said to have worked as an assistant analyst at a scientific research institute in the former Soviet Union.

"According to the Riemann mapping theorem, there is a conformal map φ maps the region Q as the upper plane U={z:Imz>0}...... Because Q is the Jordan region, it is ...... by the boundaries of the conformal map Take a fractional linear transformation of U to itself...... The vertices were kept sequentially for, again ...... by the Christoffel-Schwarz formula.

The foreign old man with gray temples in front of him knocked on the blackboard hard, and the shiny Mediterranean Sea made Elena squint her eyes unconsciously, it was difficult to read the handwriting on the blackboard, and the old man's excited voice faintly came from her ears.

"Cheer up, attention, I'm going to start deforming!"

The next moment, a bright light shone into the classroom.

The face that was covered with old age spots around her gradually dimmed, and a pale golden thing flashed before her eyes.

Elena blinked her eyes hard, and it seemed to be a somewhat familiar pair of glasses. Could it be that after studying a large number of mathematical theories, people can still become glasses......

No, you have to wake up, otherwise you will definitely fail the course at the end of the semester...... Strange, why, she vaguely rose up a bad feeling of having seen the make-up exam questions, it was so frustrating.

The girl blinked vigorously again, and the blurred classroom and light faded away, revealing Albus Dumbledore's smiling face and half-moon-shaped pale gold glasses.

"Good afternoon, Elena. Dumbledore seemed relieved and smiled.

Elena stared blankly at Dumbledore for a few seconds, her gaze slowly moving around the room, a well-lit ward, with a row of retracted curtains around the plush white bed.

Not far away, Grindelwald was talking to Madam Pomfrey softly, noticing the commotion, and the two of them stopped talking at the same time, and quickly walked towards Elena's bed.

This is undoubtedly the school infirmary at Hogwarts Castle, and this is the second time this term.

"I remember, I was in the Transfiguration class just now......"

Elena frowned, slowly raised her hand and rubbed her temples, and said sluggishly.

She felt as if she had just run three thousand meters, her whole body was filled with a kind of fatigue and soreness, and a tingling sensation kept coming from the depths of her mind, and every cell in her body seemed to cry out for hunger and exhaustion.

"Yes, but that was more than an hour ago. Dumbledore said, looking up at the wall clock on the wall, "It's been a while since class ended, so you don't have to worry about Professor McGonagall getting you back for the time being." ”

"What's wrong with me, Professor? I just remember that I ended up performing Transfiguration......

"That's just what you think, we'll get to that later. ”

Dumbledore shook his head with a serious look on his face, and turned his face to look at Miss Pomfrey, who had already walked up to the two of them, "Poppy, so, there's nothing wrong with this kid right now." Luckily, Hogwarts has you, so I'm relieved. ”

"No thanks, in fact I didn't do anything, this kid is just out of strength. ”

Madam Pomfrey shrugged, a look of confusion on her face, glanced at Elena, and said unceremoniously.

"But, I think Dumbledore needs to figure out what kind of spell this kid was casting before—just turning matches into needles, not draining all the magic of a wizard, let alone she...... Well, you know. ”

You know, when Elena was sent by Hannah and Professor McGonagall before, that pale and lifeless look frightened Madam Pomfrey. In her impression, except for the war years when spells were frequently cast, such an overdraft situation could only occur when some senior wizards tried powerful forbidden spells without their own strength.

Normally, the magic contained in a wizard's body is far higher than what she can show, and the only thing that limits her ability to cast spells is the understanding and emotions of the spell, and most wizards may not encounter such a spontaneous entry into a protective coma like this.

"Normally not, but if it's some special Transfiguration, it's possible...... I think that Miss Kaslana's bloodline determines that she may have some unusual changes in Transfiguration. ”

Without waiting for Dumbledore to answer, Grindelwald, who was standing next to him, touched his chin and explained to Madam Pomfrey with great determination in an old-fashioned tone.

"Maybe you young people haven't had much contact with Meiwa, but pure-blooded Meiwa has a natural ability to transform into a swan, a horse, an eagle, a snake or a wolf. And the half-breed girls have also inherited this talent, and they are much more powerful and dexterous than ordinary wizards in terms of transformation and spells. ”

Needless to say, in the face of Lady Pomfrey, who is a senior healer, it is impossible to hide Elena's identity as a half-breed girl - it only takes a little closer inspection of the girl's body to discover the magical blood hidden in Elena's body.

Therefore, Grindelwald has no concerns about this. As for the tone, there is nothing wrong with it, you know, his current disguise is the legendary "Paracelsus", even if Dumbledore is just a child in front of him.

"Yes? I see. ”

Having seen the ancient healing magic texts with her own eyes and Dumbledore's guarantee, Poppy Pomfrey naturally didn't have too many doubts about Grindelwald's identity, and since the elder had said so, she didn't have much to question.

Madam Pomfrey raised an eyebrow and turned her head to look at Dumbledore with a hint of condemnation in her eyes, "Then Professor Dumbledore, you should have taken this into account before she enrolled. Instead of waiting until the kid is in the infirmary......"

"Oh, ma'am. You don't have to blame Albus for this, after all, he is only a hundred years old, and he doesn't know much about the characteristics of the child born after the union of the wizard and the girl. ”

Grindelwald smiled and waved his hand, the smile on his face couldn't help but grow a little thicker, "Leave the rest to me and Albus, we still have some things to ask Miss Kaslana about to avoid similar situations in the future." You go to the auditorium for dinner first, Elena has us here. ”

"Well, that's fine. ”

Poppy Pomfrey glanced at the two old wizards in the ward, an ancestor-level healer who had refined the Philosopher's Stone and lived for hundreds of years, and one who was now considered the greatest wizard of the century, and she really had nothing to worry about—besides, these two were obviously much more specialized than she was when it came to magic.

As Madam Pomfrey left the hospital room, the unfathomable smile on Grindelwald's face collapsed instantly.

The old man turned and looked at Dumbledore with a serious look on his face, frowning.

"Well, then, tell me about it, Master Transfiguration. What happened to this white-haired ball?"

Compared to the rest of the wizards, after the previous scuffle in Salzburg, Gellert Grindelwald has a fairly clear understanding of the limits of Elena's physical abilities.

Theoretically, Elena who can perform dozens of self-strengthening magic texts, plus hundreds of healing magic texts, let alone turning matches into needles, even if she directly releases some large-scale war magic, it will not be such a serious situation.

"What the hell is going on...... Before answering this question, I need to ask a question. ”

Dumbledore pondered for a moment, then thought about taking out a small glass tube from his bosom, the bottom of which contained a small handful of black dust-like objects, faintly shimmering in the light.

"Elena, first of all, can you tell me what these things are...... Or what do you think they should be?" Dumbledore asked as he looked at Elena with a serious expression and a solemn tone in his tone that had never been seen before.

"These, the strange black dust that you left behind after you cast a Transfiguration Spell on that match—"

I don't know if it was an illusion, Gellert Grindelwald seemed to faintly hear a tremor and excitement from Dumbledore's voice, as if he was expecting something extremely terrible or elusive.

This subtle emotion has appeared almost only two or three times in Grindelwald's impression.

For example, in Godric's Hollow, the moment when the two of them established the lifelong belief of "for the greater good", or the last scene of their breakup, when Dumbledore questioned him......

"This is ......"

Elena blinked, a little hesitant.

After some time buffering, her chaotic thoughts had gradually straightened out. Recalling the scene before, in fact, she had almost guessed the reason why she fainted.

If we say that the logic of traditional nuclear weapons is through the form of nuclear fission, a terrible big mushroom is produced on the ground. Well, the kind of behavior she did before was much more powerful than the so-called neutron stream hitting uranium-235.

I don't know what kind of wind she sucked, but she actually tried to convert the light atomic elements (hydrogen and oxygen) that make up the wood into the iron element with the smallest average nucleon mass and the largest specific binding energy among the heavy atomic elements - in short, she tried to reach the end point of the nuclear fusion reaction directly through a small transformation technique.

From the point of view of energy and overall structure, if you follow the last scene she "saw" before the coma, she should have briefly broken down all the elements that make up the match into elemental matter, and then at the beginning of the fusion, directly due to insufficient function, there was a physiological automatic "tripping" phenomenon.

"Well, if I'm not mistaken, it's graphite and a little diamond, that is, diamond particles, right?"

Elena stuck out her tongue and said with some trepidation.

Hydrogen and oxygen elements naturally become gases and escape into the air at the first time, while the substances that can be formed by carbon elements are generally graphite with a flat hexagonal stable state, and diamond with a three-dimensional network structure may appear. Considering the division of energy levels, more stable graphite naturally occupies the vast majority.

Fortunately, it only stopped at the point of breaking the chemical bonds, otherwise Hogwarts might only be a pit left today.
