I just became the Pirate King, and you're telling me I also time-traveled at the same time.

Chapter 37 Gamp's Basic Laws of Transformation

Apart from Chu Yang, only a few girls from Slytherin sat quietly in the classroom.

After waiting for a long time, no new Slytherin students arrived.

Professor McGonagall's face visibly darkened.

As the school's vice-principal, having taught at Hogwarts for so many years, this was the first time she had encountered something like this.

"Does anyone know what's going on with Slytherin? Where have all the boys gone?" Professor McGonagall coldly swept across the classroom, and everyone immediately fell silent, lowering their heads in fear.

"Professor McGonagall, those boys seem to have been playing in the common room all night. They all caught a cold this morning and were taken to the infirmary by the upperclassmen."

Pansy Parkinson, with her short hair, stood up, a smug smile playing on her lips. She was happy to see those arrogant boys make fools of themselves, since her crush, Malfoy, wasn't among them anyway.

"Thank you for answering my question, Miss Parkinson, but even so, Slytherin still has to lose 5 points." Professor McGonagall, knowing the reason, looked displeased and gestured for Pansy Parkinson to sit down.

More gloating laughter came from all directions, making Pansy Parkinson, who had made a fool of herself, blush with anger.

"Quiet!" Professor McGonagall paced the classroom, speaking sternly. "Now, open your books and turn to the first section on the first page..."

Professor McGonagall began by explaining some basic knowledge about Transfiguration, mostly in a popular science style, to help students understand what Transfiguration is and its risks.

There are also some special feelings, such as what it feels like when a person transforms into an animal and their clothes and glasses become animal skin.

This unique feeling can only be experienced by Animagus, and it is a valuable experience for other wizards.

In addition, Professor McGonagall briefly mentioned the five exceptions to the fundamental law of Gamp's transformation.

Chu Yang summarized the five points as follows: It cannot transform anything other than food into food, but it can transform one type of food into another type of food, or increase the size of food.

Secondly, it cannot turn inanimate objects into living ones, or living objects into inanimate ones; polymorph cannot change the target's life level or state.

The third rule is that you cannot use polymorph spells on magical items, as the two will clash strongly due to the differences in spells and sources of magic.

Furthermore, special shapeshifting spells like Animagus also have similar limitations, namely, they cannot transform into magical creatures.

Chu Yang's understanding is that the conflict between shapeshifting and magical items (creatures) is similar to adding two unrelated or even conflicting pieces of programming code to a program, which disrupts the normal operation of the original program.

The fourth item is quantity. You can't use metamorphosis to turn one target into multiple targets. This kind of copying or creating of individuals is similar to the second item, which is beyond the reach of human beings.

The fifth rule is to create something from nothing. You cannot use transfiguration to create a substance out of thin air, even if you have seen it before or know it well.

These five special cases all involve attempts to use magic to violate the laws of "reality"!

Interestingly, Chu Yang had a feeling that these five things were not impossible to achieve. They were more like a kind of "shackle." Once one of them was broken, magic would enter a completely new realm and undergo a qualitative change.

In the first class for the new students, Professor McGonagall briefly touched on some essential points, and because most of the Slytherin freshmen were absent, she did not teach any spells.

"Let's review what I just covered," Professor McGonagall said, before transforming back into a tabby cat and sitting upright on the lectern, her cat eyes revealing a human-like weariness.

After a brief silence, four figures burst into the classroom: Harry, the savior, and his friend Ron, along with Goyle and Crabbe, whose cheeks were swollen.

"Oh, thank goodness Professor McGonagall isn't here, otherwise we'd be in real trouble. She looks so serious, she could scare you to death when she's not saying a word!"

Ron grumbled as he pulled Harry toward his seat, completely unaware that Harry's expression had changed.

Professor McGonagall transformed back into human form from her tabby cat form, but merely passed by them; her target was the late-arriving Goyle and Crabbe.

"I heard you had so much fun last night that you don't even want to come to Transfiguration class tomorrow? Should I tell Headmaster Dumbledore to let Slytherin teach Transfiguration on their own?"

Professor McGonagall's face was frosty, and her voice was not loud, but every word she spoke pierced the hearts of Goyle and Crabbe. They now regretted not sleeping on the floor yesterday, otherwise they could have gone to the infirmary with the others for treatment.

"That's not how it is, Professor McGonagall, let me explain." Goyle hurriedly tried to explain, then felt someone gently tugging at the hem of his robe. He turned around and saw Crabbe, and also Chu Yang's amused smile.

In an instant, Gao Er felt a chill run down his spine, as if an electric current was flowing through his body. He still remembered Chu Yang's feat of single-handedly taking down the entire first-year boys' dormitory last night.

How many punches can I take?

Not even one punch!

"We're so sorry, Professor McGonagall, we promise it won't happen again!" Goyle quickly admitted his mistake and then obediently shut his mouth.

Professor McGonagall paused, still waiting for an explanation...

"There won't be a next time!" Professor McGonagall's eyes widened, and she shouted, "Sit down!"

Gore and Crabbe sat down, but they couldn't concentrate on the lesson at all, fidgeting as if there were nails on the bench.

The reason they acted this way was because their seats were right in front of Chu Yang. Even without turning around, they could clearly feel the tangible gaze sweeping over them from behind.

The Slytherin girls had planned to ask Goyle and Crabbe some specific questions, but the two of them remained motionless, like statues in the hall, eyes downcast, until the next class.

The Potions classroom was in the dungeon, not far from the entrance to the Slytherin common room. The entire corridor leading to the Potions classroom was dark and damp, and most of the new students had fear on their faces.

The atmosphere here is far too eerie, and it puts a lot of psychological pressure on a group of 11-year-old children.

Hermione, who had originally planned not to speak to Chu Yang all day, quickened her pace and moved closer to him.

Hermione coughed and said sarcastically, "Your students are really something, making Professor McGonagall so angry on the very first day of school."

Chu Yang nodded noncommittally and said, "I also think they are quite capable."
