The Transfiguration professor at Hogwarts is always up for business

The Scottish Highlands in June are ethereal like a gift from heaven.

Looking around, there are no dangerous mountains and steep peaks here, and the curves of the mountains are mixed and gentle, as if they are stacked with small green steamed buns.

Clusters of streams trickled down quietly, forming a wave of flat lake at the bottom where the small steamed buns meet.

The water and the sky correspond, and it is difficult to judge who is clearer.

"Girls and boys, look at the beautiful scenery under your feet. I don't think anyone wants to let this beauty die." Standing on the top of the mountain, Aini looked at the black heads opposite, feeling a little proud in his heart.

Dumbledore notified him this morning that he could end his substitute class and return to his job. It seemed that Snape had finished his outside work.

There is less than a month until the end of the semester, and all the content of transfiguration in the lower grades has been taught, and the general review has entered ahead of schedule.

In the afternoon, Aini and the professors of other subjects switched courses, which made the scale of this outdoor class three times larger than the previous one.

The little wizards from grades [-] to [-] gathered together and wandered among the green mountains and green waters. They felt that their memory was much better. They felt that they could clearly remember the application of transfiguration taught by Aini without reviewing.

The power of magic is related to the understanding and proficiency of the spell, the strength of the magic power, the magic wand and other factors, but the actual effect of the same spell power is very different.

The content of this aspect is mainly taught in the Defense Against the Dark Arts class. In view of the special circumstances of the Hogwarts Defense Against the Dark Arts class over the years, there has been a large gap in the teaching of spell application.

In this regard, the fourth grade students are not much better than the freshmen, it is nothing more than mastering a little more spells and the power of the spells is a little bit stronger.

Of course, this also has an advantage, so that when Aini lectures on relevant aspects, he can gather students of several grades together to give concentrated lectures.

Comfortable, leisurely, lazy.jpg

Cough, cross this sentence out.

The little wizards looked at the surrounding scenery, and the distant mountains and flat lakes that filled their vision directly crashed into their hearts through their eyes. They suddenly felt that they had become clear, and they only hoped that this place would always maintain the current style.

"Professor, will mountains and lakes die too?"

"Is it the Muggle contamination?"

"Is it possible to cast a large Muggle banishment spell on this place?"

……

The little wizards twittered and asked all kinds of questions, which made Aini feel a little headache.

Next time, it will be limited to a class of one grade, with 60 students, he really can't hold it.

"Nature will not perish, but the environment may undergo tremendous changes. The mountains may not change, but the verdure may perish. The green water may flow for a long time, but it may be dirty and full of debris."

Aini's voice became low, and the little wizard's mood was no longer upbeat. Thinking of the scene he just described, many people shuddered, and looked at the green mountains and green waters with a trace of worry in their eyes.

"Excessive deforestation, excessive emissions, and all kinds of pollution will indeed make the environment worse, but there is also another behavior that will seriously damage the environment we depend on."

Aini waved his wand, and dozens of pictures appeared above, with hooded wizards performing various black magic.

"In fact, the lethality of many spells is not inferior to that of black magic, but the reason why black magic is separated as a system is because the use of black magic will cause fundamental damage to our world."

"Regular magic is the application of magic power. The ability to cast one's own magic level is taken from nature and then returned to nature. The magic power will not be reduced because of this."

"Black magic is different, not only black magic is powerful, there are many powerful spells in conventional magic, but they are more difficult to cast than black magic of the same power."

Aini waved his hand again, and many wizards in white robes appeared on the screen above, and they cast powerful conventional magic to defeat the black wizards one after another.

"The reason why black magic can show greater power under the same difficulty is because black magic is burning magic power, and the disappearance of magic power will burst out more powerful energy, but since then this part of magic power has been removed from our world. Disappeared."

"This is an extremely terrifying thing. If things go on like this, the world will become a desert of magic power. In fact, whether it is wizards or Muggles, animals or plants, the growth of all things cannot be separated from magic power. The only difference is how much it needs."

"Once the magic in the world is exhausted, all that remains will be barrenness."

Aini lifted the magic projection, looked at the little wizard in front of him and said word by word: "Therefore, while using black magic to gain strength, it will gradually lose the favor of the world and be eroded by black magic. Famous dark wizards all end up miserable, I hope everyone can learn from it, protect themselves, and better safeguard our world."

After Aini finished speaking, even the Slytherin students fell into deep thought. Even though some students had already started to learn black magic, they were only in the fourth grade. The added words made them resist black magic.

Ravenclaw students are more interested in the relationship between magic power and life that Aini said, and have already considered asking Aini for advice after class.

The little badgers of Hufflepuff agreed. For Ernie, they are the last thing to worry about. They don’t like black magic at all. Hufflepuff students are the most receptive to Ernie’s spiritual hints. .

The most surprising thing is that most of the Gryffindor students don't take it seriously. They never thought about learning black magic, destroying the world or something. It doesn't exist. If they can save the world, they are very interested .

As for Aini, he was a little dizzy, and gave spiritual hints to more than 100 people together. Even with his mental strength, it was still a little bit reluctant. If it wasn't for his good physique, he might be bleeding from his nose now.

Back to Hogwarts with some silent little wizards, today's half-day tour of the Scottish Highlands officially ended.

As soon as he stepped into the gate of the castle, he saw Filch falling asleep leaning on the porch pillar.

"Filch, Mr. Filch, wake up." Signaling the students to leave first, Ernie stepped forward and shook Argus Filch awake. Rich in Hogwarts, it seems that the cold virus has also evolved.

Seeing this, Fred hurriedly took George and ran away first, still wondering if something happened that made Filch block them at the door.

There were also a few Gryffindor students who, full of guilt, followed the twins into the crowd and ran away first, causing a lot of dissatisfied complaints.

"Professor Scamander, Principal Dumbledore is waiting for you in the office." Filch opened his eyes and was about to yell when he saw Aini standing in front of him, and swallowed the remaining half of his breath. Said to Aini in a hurry.
