Hogwarts: Is this junior good or evil?

At this time, Professor McGonagall drew out her wand and just pointed lightly, and the podium in front of her quickly turned into a big pink fat pig. Just as the fat pig spread its four hooves and ran, Professor McGonagall pointed again, and the fat pig turned back into the podium.

This scene made the little wizards very excited, and screamed in surprise. At the same time, everyone also developed a strong interest in the Transfiguration class.

"Transfiguration has four branches: Transformation, Switching, Conjuration, and Vanishment."

"Transfiguration refers to a collection of magic that changes the target's form in any way, including high-level transformations such as cross-species transformation and human body transformation..."

Professor McGonagall described the general outline of Transfiguration in detail, allowing the young wizards to have a preliminary understanding of Transfiguration.

Then she changed the subject and said, "Today, we are going to learn the most basic Transfiguration, the introduction to non-biological Transfiguration, which is to turn a match into a needle."

Professor McGonagall took out her wand and waved it gently, and neat calculation formulas appeared one by one on the blackboard: "First, let's talk about matches. Matches are made up of match heads and matchsticks. The main component of the match head is..."

As Professor McGonagall continued to teach, Yang Tian's mouth gradually opened wider. He was completely dumbfounded. He finally understood why Professor McGonagall said Transfiguration was the most complicated.

Through Professor McGonagall's explanation, Yang Tian discovered that Transfiguration is actually the science of magic. Don't feel contradictory, in Yang Tian's view, Transfiguration is actually magic derived from a series of calculation formulas that conform to the rules of magic.

For example, to turn a match into a needle, the caster must first understand the structure, composition, density and other data of the match and the needle, and then calculate the casting process through the corresponding formula. Can you believe this?

However, he had no time to sigh at this moment. He quickly followed Professor McGonagall's explanation and applied a series of formulas in his mind to deduce. For this purpose, Yang Tian also specially used 1% of the computing speed of the intelligent brain to improve the computing speed and accuracy. He also wrote down a lot of complex and difficult notes for this purpose.

After nearly 20 minutes of teaching, Professor McGonagall finally finished explaining the formula for turning a match into a needle. She began to distribute a match to each little wizard and asked everyone to try to perform Transfiguration.

The young wizards were very excited and drew their wands to wave. But the result was predictable, and everyone felt as if a bucket of cold water had been poured over their heads.

The matches in front of many young wizards lay quietly on the table without any changes. What's more, a Gryffindor wizard named Seamus Finnigan made his matches explode.

Looking at this little wizard with a dark face and who seemed to be frightened, Yang Tianming realized that this was the so-called explosive genius, right? He really lived up to his reputation.

Of course, not all little wizards gained nothing. For example, our Miss Know-it-all, after several experiments, finally made the match closer to the shape of a needle. Although it changed back quickly, it still attracted the attention of Professor McGonagall: "Very good, this is a good start, isn't it? Miss Granger's excellent performance, Ravenclaw +5 points."

Hermione's cheeks flushed with excitement after receiving the praise. She turned her head and looked at Yang Tian triumphantly, thinking that she was finally better than him.

But after turning around, Hermione was dumbfounded. Yang Tian didn't cast any spell on the matches at all. Instead, he stared at his notes stupidly, as if he was in a daze, or thinking.

Professor McGonagall also noticed Yang Tian's actions. She walked up to him with a little dissatisfaction and said, "Instead of thinking about those things, it is better to do it in practice."

Yang Tian, ​​who was lost in thought, was slightly startled. He apologetically pulled out his ancient magic wand, closed his eyes and thought for a while. When he opened his eyes again, he was already waving the magic wand decisively.

With Yang Tian's graceful movements, a match gradually turned into a needle at a speed visible to the naked eye, but Yang Tian could feel that there was a reverse resistance force that seemed to prevent this from happening, and was even trying to restore it to its previous state.

Yang Tian frowned and slightly increased the output of magic power. After another moment, the transformation was finally completed, and a shiny thin needle appeared on the table.

Professor McGonagall picked up the needle in amazement and examined it carefully. "I have to say, it's perfect. It's slender and shiny, and the details are perfect. Wow, the texture and weight are also within consideration. It's impeccable. In view of Mr. Yang's excellent performance, Ravenclaw gets +10 points."

However, Professor McGonagall quickly came back to her senses and said confidently, "Mr. Yang, you should have reviewed the Transfiguration course before, right?"

Yang Tian smiled awkwardly and said, "I'm sorry, Professor McGonagall, my family is not proficient in Transfiguration, so I have never learned relevant knowledge before. Today is my first time to come into contact with the course of Transfiguration.

Professor McGonagall looked incredulous after hearing this, but she did not pursue the matter. Instead, she asked another question: "Mr. Yang, what were you thinking about before the actual operation just now?"

Yang Tian replied respectfully: "Professor, just now when I was deducing the casting process according to your explanation, I found that the values ​​I got were slightly different from the values ​​you explained, so I was thinking about the reason."

Yang Tian's answer immediately aroused Professor McGonagall's interest, and she asked, "Tell me, which values ​​are inconsistent?"

Yang Tian did not hesitate and answered: "Almost all are different." As he spoke, Yang Tian had already pulled out his ancient magic wand and pointed to the blackboard: "For example, here, according to the formula, the magic power consumed to remove the wood attribute should be 11.34J, but the value given at that time was actually 11.67J. And here, the magic power consumed to extract the weight..."

As Yang Tian continued to explain, Professor McGonagall's eyes became brighter and brighter, and in the end they were even filled with incredible doting.

All the little wizards in the classroom were speechless and just stared at Yang Tian's speech. Hermione was even more incredulous and frantically calculated on the draft paper following Yang Tian's speech.

After Yang Tian finished speaking, Professor McGonagall asked expectantly, "Do you understand the reason now?"

Yang Tian sincerely sighed: "I understand, professor. When I actually practiced it, I understood the reason. Just like you said, instead of thinking about those things, it is better to actually practice it."

"When I cast magic according to the value I deduced, I found that there was a counter-force. Its value was exactly the difference between the value you gave and the calculated value. I have to say, all this is really amazing."

Compared to Yang Tian, ​​Professor McGonagall seemed more excited: "Merlin, what did I find out? This is indeed your first time to come into contact with Transfiguration, but most young wizards can only discover the details of it much later, and you only took half a class."

"A mind as smart as a demon, a precise and demanding control, an almost crazy spirit of exploration... If I could, I would even like to give you another 50 points. Unfortunately, I can't do that, kid, because it would be unfair to other colleges. So, come to my office after class and we can talk."

Yang Tian happily replied, "Okay, Professor McGonagall."

The little wizards didn’t know what to say anymore. They all looked at Yang Tian with admiration.

But no one paid any attention to it. At this moment, in a certain area at the back of the classroom, Harry was looking at his good friend Ron with suspicion, while Ron lowered his head in embarrassment. No one knew what happened between the two of them...
