Huh? There's a magic school here.

After dinner, as all the young wizards gradually returned to their dormitories, they saw a piece of bad news posted on the bulletin board: today's Charms class wouldn't be a waste; they had to do homework. Fortunately, it only needed to be written on twelve-inch pieces of parchment. Today's class had still given them a lot of insights and inspiration. Like the author, padding out the word count wouldn't be a problem at all.

Meanwhile, their male student council president and four prefects arrived at the Ravenclaw Dean's office on the eighth floor with great joy. There were only ten of them who could get special treatment, so they had to make the most of it, otherwise they would lose face if they couldn't control the other students later.

So the five of them asked Professor Flitwick about the parts and details they hadn't understood during the day, and Flitwick patiently answered them all. Fortunately, the first day's material was mostly theoretical, so as long as they understood it, it was fine. Soon, the group of five left, but instead of returning to their dorm, they went to the study room together to discuss and do their homework for the day.

In the evening, Andres continued reading and waited for his system points to arrive. He urgently needed to materialize another study room. The reason he wanted to expand it rather than upgrade the existing one was because he found that the young wizards were still studying very diligently. The study room was packed after dinner, forcing latecomers to return to the common room to study.

So when the system notified him that his system points had increased by 68, Andres immediately opened the system shop and redeemed a study room card. He went to the fifth floor alone and tried using the card on his original classroom, but the system notified him that he did not have enough cards to upgrade and asked him to purchase more.

"Study Room (Level 1): The master leads you through the door, but the practice is up to you! In addition to listening attentively in class, young wizards should also practice magic after class. The learning efficiency in this room increases by 5% for each level it goes up."

After dealing with this matter, I returned to the headmaster's office. I wrote a notice on parchment, telling all the young wizards in the house that there was nowhere to study. Don't worry, the headmaster has prepared another study room for you. It's on the fifth floor; find it yourself, etc.

They copied it in pairs, making a total of four copies. They called Dobby over and gave him the task of posting it on the bulletin board so that the little wizards would receive this surprise when they woke up the next morning.

Sure enough, the next morning, every young wizard in every college checked the notice board before leaving home. They all expressed that they would no longer have to worry about missing out on study room seats if they ate too slowly. It was reminiscent of the frantic rush to the library to grab study spots in a certain Eastern country for postgraduate entrance exams.

9:30 a.m., the Transfiguration classroom on the first floor of Hogwarts Castle.

All the young wizards arrived at the Transfiguration classroom early, and after taking their seats, they all looked at their textbooks. Occasionally, they would steal a glance at the tabby cat perched on the podium. All the young wizards knew that the standard silver tabby American Shorthair was Professor McGonagall.

That classic scene from the movie left a deep impression on them, and Professor McGonagall herself knew that her students understood she was an Animagus. However, she was used to giving the young wizards a shock in the first class. Through these little tricks, she could effectively increase their interest in Transfiguration, which was an experience she had summarized after teaching at Hogwarts for many years.

When class started, the tabby cat leaped down and landed, transforming back into Professor McGonagall. Even though the young wizards were somewhat prepared, they were still stunned by the sight and exclaimed in amazement.

Professor McGonagall nodded in satisfaction, then waved her wand and the lectern transformed into a roaring lion, which roared at the young wizards. With another wave of her wand, the majestic lion transformed into a giant python coiled in a snake formation.

Just as the giant python stretched out its head to probe the surrounding scents, Professor McGonagall waved her wand, and the python transformed into an eagle. As the eagle spread its wings, ready to take flight, Professor McGonagall waved her wand again, and the eagle transformed into a badger.

Finally, after spinning around a few times, Professor McGonagall transformed the badger back into the lectern. The young wizards screamed, felt fear, envy, and eventually, adoration with each transformation. After witnessing these transformations, they looked at Professor McGonagall with eyes full of curiosity.

"Well, as you all see, this is the charm of Transfiguration. It's good to have a thirst for knowledge, and I hope you can maintain it. At the same time, you must understand that you still have a long way to go before you can perform Transfiguration like I do."

Alright, welcome to my Transfiguration class. I will teach you everything you need to know about Transfiguration. You should know that as wizards, Transfiguration is essential for you. Therefore, it is a compulsory course at Hogwarts School of Witchcraft and Wizardry.

In this course, I will teach you how to change the shape and appearance of an object. This kind of magic is generally called transfiguration.

Theoretically speaking, we cannot conjure any basic matter out of thin air, but we can transform it. For example, the spell I just cast on this lectern was one such transformation.

Like Charms, Transfiguration has many branches, and the Animagus I just mentioned is one of them. Other branches include summoning, revealing, cross-species transformation, and human transformation.

Of course, Transfiguration is also very complex and dangerous, and you need to work very hard and diligently in this subject. I hope everyone will treat Transfiguration with great caution, and you are not allowed to use Transfiguration on any classmate, because you could potentially cause permanent damage to them.

There are many famous examples in the magical world of failed Transfiguration spells, such as those involving halflings. Medusa, the Hydra enchantress, is a classic example of this. After transforming herself into that grotesque form, she abandoned her true self and wreaked havoc in the Muggle world, ultimately being killed by a sword.

The Sphinx was an Egyptian sorcerer who, after a failed spell, lost his mind and gradually transformed into an irritable beast. Therefore, it is widely believed in the magical world that whether the upper or lower body is transformed into a monster, the damage to a wizard's intellect and body is permanent and irreversible. Thus, spells must be recited clearly and the mind must be fully focused when casting them.

Okay, let's stop there. Let's talk about five key points to keep in mind when using Transfiguration. I hope you'll write these down; they might be on your final exams. First, you can't conjure food. Second, the transformed object doesn't possess true life. Third, you can't conjure items with magical properties. Fourth, you can't conjure unknown things. Fifth, you can't change the quantity of matter during Transfiguration.
