As Malfoy and the others left the Forbidden Forest and entered St. Mungo's Hospital, the first event of the Triwizard Tournament finally came to an end.

Compared to the student division, the Death Eaters competition was bloodier, more violent, and had a higher mortality rate.

Here is to highlight the advantages of being fully enclosed, there is no broadcast picture, no audience, no report, it is easy to operate in the dark, not to mention, if the warrior dies, it can be treated coldly.

Of course, there are still some rumors that some of the students' fathers are being warriors, such as Malfoy.

He even took Goyle and Crabbe to desperately promote it, trying to make everyone know that the Triwizard Tournament had killed many people, and it was full of shady and crime.

But unfortunately, no one paid attention to him at all, and all the attention of the little wizards was attracted by another piece of gossip, so that they were a little absent-minded even in class.

During Wednesday's Transfiguration class, Professor McGonagall also noticed the students' distractions, and she stood on the podium and had to raise her voice:

"When trans-species metamorphosis, in addition to obeying Gamp's basic deformation law, it is also necessary to observe Portolemie's third transfiguration principle, that is, the transcultural creature must meet the physiological structure and habits-"

Professor McGonagall waved her wand, and with a slight pop, the guinea fowl turned into a butterfly.

"So this arrow-ring butterfly, can anyone tell me what's wrong?"

Rove observed the arrow-ringed butterfly, raised his hand and replied:

"Butterflies stand firm when they are at rest, but this butterfly has wings spread flat on its back, which is the habit of moths."

"Very good, very careful observation, Hufflepuff plus two points." Professor McGonagall said, "Anything else? ”

For a while, no one spoke in the classroom, and Rove looked at the butterfly, although he felt that it had a slight sense of disobedience, but he couldn't think of anything wrong for a while.

He gently touched Shirley with his elbow and asked in a low voice, "You know what?" ”

Shirley nodded, and was about to answer when Professor McGonagall, who noticed this scene, asked first, "Miss Swinton?" ”

The ponytail girl had no choice but to stand up and replied softly:

"The ratio of the length of the arrow-ring butterfly to the length of the wings spread out seems to be close to one to one, but the real length ratio should be close to PHI - 0.618."

Rove raised his eyebrows, no wonder he always felt a little discordant, it turned out that it was not in line with the golden section.

"Good, very good, Ravenclaw plus five points." Professor McGonagall looked at Shirley with satisfaction and smiled:

"Cross-species transformation is not the same as the transformation of an object, the transformation of an object can have any shape, but the cross-species transformation must conform to the biological structure.

You want to be a cat, but you have a dog's tail, that's a mistake, and not being in the golden ratio is also an easy mistake to make. ”

"In fact, most animals in nature – the ratio of the diameter of each rib of the nautilus to the diameter of the adjacent ribs, the segmentation of the insect – fits perfectly into the golden section."

"When you are in the sixth grade, when you come into contact with the deformation of the human body, you will also focus on this law - the three bones of each finger of the human being, all forming the golden ratio, the shape of the human ear, are designed to be a perfect spiral, like a nautilus."

"That's why many wizards are seen through at a glance when they become other people, which is not in line with the human ......."

Many students hurriedly took notes, but many more young wizards did not put pen to paper, and were still whispering, completely distracted from the class.

Rove saw Professor McGonagall purse her lips tightly, a small gesture that was clearly a precursor to anger.

Sure enough, the next second, the annoyed voice crackled in the classroom like a whip.

"Seriously, I think my lecture was quite exciting, and there wasn't too much boring." Professor McGonagall looked around and said angrily:

"Why are you all so distracted that you don't even take notes, can you?"

The students immediately took out their quill pens and began to write, and Professor McGonagall named them:

"Miss Abbot, you've been whispering to Susan Bones all the time, what are you two talking about, so engaged?"

Hannah stood up tremblingly and said, "I'm sorry Professor, we were just talking about the Triwizard Tournament......"

"It's been a long time since the first round of the tournament ended, and it's not enough for the two of you to discuss?!"

"It's not about the competition, it's about ......" Hannah hesitated for a moment and confessed, "It's about the ball, we heard that Hogwarts is going to hold a ball." ”

"Who did you listen to?" Professor McGonagall asked.

"Everybody says that." Hannah boldly asked, "Professor, is it true?" ”

Professor McGonagall didn't want to say it, but seeing that the students were staring at her expectantly, she nodded:

"That's right, the ball will take place at 8pm on Christmas night in the auditorium and end at 12 a.m. – a traditional part of the Triwizard Tournament and a great opportunity for us to socialize with foreign guests."

The students erupted in thunderous cheers with excitement that immediately resounded throughout the classroom.

Shirley was also stunned when she heard this, she heard her roommate in the dormitory talk about the prom, she thought it was false news, but she didn't expect it to be true.

The ponytail girl glanced quietly at someone out of the corner of her eye, but Rove was keeping his head down, scribbling down notes.

"Professor McGonagall," a Ravenclaw boy sitting in the back row raised his hand and asked hopefully, "Is there a limit to who can be invited to dance?" ”

"Nope." Professor McGonagall shook her head, "You can invite anyone, preferably Beauxbatons and Durmstrang students, and of course, our junior and senior students......

Justin whistled and asked, "Is it okay to invite boys?" ”

The crowd laughed, and some people applauded him.

"Of course, Mr. Justin Finchrie, it's your freedom." Professor McGonagall made a rare joke:

"But I have to give it to you...... And a little advice from those who have come before. ”

"You'd better hurry up and choose your favorite dance partner, and then send out the invitation directly, and hesitate until the days when the dance party is about to start, and you will find that the good girl has already been invited away."

The girls smiled knowingly and nodded their heads as if they were the good girls Professor McGonagall had come up with.

The boys all looked at each other thoughtfully, and some glanced at Shirley, who was sitting in the first row.

"It's the same for girls." Professor McGonagall blinked, "Brilliant boys, but they're all in demand, don't hesitate." ”

Rove immediately felt a group of hot eyes stop at him, and there was a rush of whispers and laughter.

"One more thing," said Professor McGonagall, looking at Rove and Shirley, "it is customary for the Warriors and their partners to dance. ”

"Scamander and Miss Swinton, you two can't miss the Ball, you must invite your dance partners to the dance."

Rove had known about this for a long time, so he didn't pay much attention to it, but Neville on the side couldn't wait to ask:

"Rove, who are you going to invite?"

Shirley, who was just looking at the teenager out of the corner of her eye, immediately turned her head and looked at Rove.

Neville continued, "Shirley, Hermione, or Sister Delacul?

Or, the twin Petyr sisters, who I think are pretty both, and Ginny of the Weasleys, who seems to come to you a lot, and Slytherin Linda Avery, who is a big fan of yours and who has formed the Scamander Workshop at Slytherin House......"

Rove: "......"
