When Professor McGonagall praised Dudley and invited him to help, her expression remained as serious as ever.
Those who didn't know might think she had a grudge against Dudley and was deliberately picking on him!
Those who knew... well, she did have a grudge against Dudley.
But given her personality and kindness, she would never deliberately pick on anyone.
Dudley was absolutely sure of this. He obediently stood beside Professor McGonagall, feeling secretly pleased.
Professor McGonagall clearly disliked him, yet she had to admit his strength.
This feeling was indescribably wonderful.
"Professor McGonagall, what do you need me to do?" Dudley asked.
"Please, Teaching Assistant Dursley, first demonstrate your understanding of transfiguration. Then, I'll supplement the content of today's class. Finally, we'll patrol the classroom together to help the students perform the simplest transfiguration spells."
Professor McGonagall had a clear plan. Having an assistant would greatly speed up her teaching progress.
"Alright, then I'll just say what I want and give it my all!"
Dudley readily agreed. Teaching others is also a way to deepen one's own knowledge and skills.
As his imagination and mental power were continuously developed, and his magic knowledge and skills became more proficient, his magic power would also increase.
He could feel that his magic power had increased by about one - third compared to when he first fused the The Philosopher's Stone.
The spell - casting technique he obtained when fusing Quirrell's cracked wand played a major role.
While thinking, Dudley held the Smelting stick and quickly walked to the empty space beside the podium. Then he began his explanation and demonstration:
"Transfiguration, as the name suggests, is a magic that turns one thing into another.
In this process of transformation, there are three key points. One is the output of magic power, the second is precise imagination, and the third is a specific understanding of the things involved.
For example, I want to turn this hardwood stick in my hand into an iron sword."
With a wave of Dudley's hand, the Smelting stick turned into a fine iron sword with exquisite patterns. The blade of the sword glistened with a sharp cold light.
"In this process, I stably outputted a burst of magic power. This magic power can keep the stick in the form of a sword for ten minutes.
At the same time, before the transformation, I imagined the shape, size, material and other details of the sword in my mind. This requires me to have precise imagination and a specific understanding of information such as'sword' and 'iron'.
If I've never seen what iron is or never known what a sword is, no matter how high my magic power is, it would be difficult for me to precisely transform the stick into such a sword.
So, if you want to use transfiguration flexibly, you must observe and experience different kinds of things in daily life and keep them in mind as materials for performing transfiguration."
Of course, magic is idealistic. We don't need to delve deeply into the composition of certain materials or study the principles behind the composition of complex objects. We just need to form basic cognitive concepts in our minds to successfully perform transfiguration.
For example, I don't know the specific mechanical principles inside a pocket watch. I only know that a pocket watch is a time - keeping tool, but I can still transform something into a fully functional pocket watch."
As Dudley said, he waved his hand again, and the sharp sword transformed into a golden pocket watch with ticking hands.
"Another example. I don't fully understand the internal organs, blood, and skeletal structure of a lion. I've only watched documentaries about lions, yet I can still conjure up a seemingly real - life lion."
Dudley tossed the pocket watch in his hand forward, and it turned into a vivid, flesh - and - blood lion, roaring with its head held high, which involuntarily made the first - years below utter an impressed "Wow!"
"But note that we are not creators. The living beings we conjure have no soul.
Moreover, if I don't continuously output my magic power to control this lion, it will only repeat the few actions I set during the transformation until the magic power maintaining the transformation is exhausted and it reverts to its original form, which is my Smelting stick."
Sure enough, the lion Dudley conjured kept repeating the actions of raising its head, opening its mouth, and roaring.
Not until Dudley infused more magic power into the lion did it close its mouth and start walking around.
"One more thing I want to remind you all of is that transfiguration can't turn non - edible things into edible food. For instance, if I transform my Smelting stick into a plate of cakes, it only looks delicious and edible - looking."
Dudley pointed into the air, and the wandering lion transformed into a plate of strawberry cream cakes floating in mid - air, tempting the first - years' appetites. Then it slowly fell back into Dudley's hand and reverted to the original appearance of the Smelting stick.
Dudley stabbed the Smelting stick on the ground, making a dull sound, and finally stated:
"When you learn transfiguration, you should start from small and easy tasks to bigger and more difficult ones gradually.
Begin with small - sized items. First, try to change their appearance, like turning a wooden stick into a wooden sword. Then, attempt to change their material, such as turning a wooden sword into an iron sword. Once your magic power improves, try transforming inanimate objects into living ones and vice versa."
"Clap, clap, clap, clap..."
After Dudley finished his speech, Professor McGonagall couldn't hold back her serious expression any longer and took the lead in applauding for Dudley.
The look in her eyes when she looked at Dudley was full of admiration and astonishment, as well as a hint of helplessness.
Obviously, Professor McGonagall highly appreciated Dudley's strength and talent, but she couldn't bring herself to like his rough - and - rude behavior.
Dudley didn't really care about what Professor McGonagall thought of him. After he finished speaking, he nodded at Professor McGonagall and gave up the podium to her.
"I don't even know what else to add. Teaching Assistant Dursley's explanation was vivid and concise, hitting upon the essence of transfiguration spells.
As a guide for beginners, I'll add one thing. When performing transfiguration, ensure that your magic power corresponds to the intended transformation effect. At the same time, you can use the incantation Instant Transformation as an aid.
In this class, your task is to transform the matches in the box on your desks into a needle. It would be best if you can turn it into a metal needle. If you can't change the material but simply transform it into an obvious needle shape, you can also get extra points."
Professor McGonagall walked onto the podium, added some knowledge content, and then handed out the in - class assignment. She arranged for Dudley to work with her, dividing the areas, walking around the classroom, and giving individual guidance.
Guiding the children to cast spells was much more difficult than making random transformations on stage.
At first, Dudley didn't think this would be difficult at all. But after encountering some students from Gryffindor and Hufflepuff, including a very few hard - to - teach ones and even some extremely challenging cases, his patience and perseverance were greatly tested and tempered, and finally he made significant improvement.
After finally guiding two or three "students with potential" who could barely transform the matches into wooden needles with an eye - hole, this Transfiguration class was finally over.
