Led by Professor Sprout, the students picked up their dragon skin gloves and bottles and began to collect the Babo tuber pus.

However, collecting pus may seem simple, but when it comes to practice, various problems will arise.

Everything else is easy to solve, but the biggest trouble is that the tubers of Babo are covered with pus, and when you squeeze hard, each pustule is like a ripe pimple, spraying outward.

Not to mention that those pus are extremely precious, and every drop that falls is a serious waste, and once it is splashed on yourself and others, it will also cause damage to the skin.

Rove, Hermione, and Neville worked in a trio to collect three vials of pus with ease, with no injuries and no waste.

Professor Sprout was satisfied, and gave them more house points.

Hannah hurriedly wiped the sweat from her forehead and asked in amazement, "How did you do that?"

"yes." Susan had a rag over her face, and she didn't want to be disfigured at such a young age.

Many people looked at them and wanted to learn the art of "squeezing acne".

"The movements must be gentle, not too rough." Rove raised his right hand and said, "Pay attention to my technique, I'll show you this."

The boy picked up a plump, liquid-filled steamed bun-shaped babo tuber and stroked it gently, with very gentle movements, almost without force.

Under Rove's caressing, the soft pink bulge at the top of a bulge gradually straightened, and the boy clamped it between his thumb and forefinger and slowly rubbed it with his fingers.

Rove kneaded and fiddled with the glass bottle for about ten seconds, and then he squeezed it lightly, and the liquid gurgled down the swollen bulge like milk.

The little wizards all seemed to have opened the door to a new world, and they couldn't wait to perform the ...... of Rove's demonstration Rub the dragon's claw hands.

However, Lavender and Ron don't know if it was accidental, or if it was intentional, and both pointed the Babo tubers at each other when taking the pus.

Lavender and Ron were sprayed with pus from each other, and Harry, who was standing aside to help, was also splashed with sticky lake liquid.

The three were taken to the school hospital together.

After the herb class, Gryffindor went to the Conservation of Magical Beasts class, while the Hufflepuff students hurried to the Transfiguration class.

The Ravenclaw students had arrived, and Shirley sat quietly in the first row, watching Transfiguration Today intently.

Rove took the box and sat down beside the girl, she looked up, sniffed closer, and asked, "What's the smell of gasoline?"

"To be exact," Rove explained, pulling out his books, summer homework, and quills, "the smell of Babo's tuber pus."

He deliberately waved his sleeve at the tip of the ponytail girl's nose and smiled, "It smells good, right?"

A light smile appeared on Shirley's face, and she shook her head and said, "It doesn't smell good."

"Then disappear...... The smell is gone." Rove raised his wand and waved it at himself, and when the smell on his body had been removed by magic, he whispered:

"Actually, I kind of like the smell of gasoline."

Shirley tilted her head and looked at Rove, looking cute that I don't read much, don't lie to me.

"Really." Rove explained with a smile:

"Gasoline contains aromatic hydrocarbons that stimulate sensory cells to cause a certain pleasure, which Muggles call the abuse and addiction of volatile organic solvents.

However, smoking too much is not good for the body, and it is easy to become addictive."

Of course, some people are addicted, and naturally some people hate the smell of gasoline and diesel...... Just like coriander and durian, there is love and hatred of the party.

Seeing Shirley holding up her cheeks in a daze, Rove picked up the quill, nodded her delicate nose with a phoenix tail feather, and asked, "What are you thinking?"

Shirley came back to her senses and wrinkled her nose, "I was thinking about the addiction to volatile organic solvents you just mentioned."

"Oh, you also have a taste of addiction?"

The ponytailed girl looked embarrassed, she hesitated for a moment, but still said boldly, "I like it...... The smell of you."

"This can be done

addiction, no danger, and good for physical and mental health."

Rove grinned, grabbed Shirley's ponytail, pulled it to the tip of his nose and sniffed hard, and said softly, "I like the smell of you, too."

Shirley blushed, glared at him lightly, and said:

"That's a nice sound, but I heard an interesting rumor in the morning."

The smile on Rove's face froze, and he hurriedly explained:

"I went to see Professor Dumbledore last night, I didn't date Helena, it's all rumors, don't listen to their nonsense."

Shirley laughed, "I know you don't, I actually wanted to talk about the rumors about Eloise Meadgan's nose."

As soon as Rove breathed a sigh of relief, the ponytail girl said quietly, "But why do you want to make a rumor about you and Helena?"

Rove looked at Shirley, who was a little saved, held back a smile, and whispered:

"I'll kiss you now in front of the whole class, and everyone will definitely make rumors about the two of us in the future."

Seeing the young man make a gesture of a hungry tiger pounceing on a sheep, Shirley's cheeks were slightly red, and she hurriedly said, "Don't make trouble......

"What are you two doing?" A familiar voice rang out suddenly.

The boy and girl were startled, and turned to see Professor McGonagall who had come at some point, standing at the table, looking at them both with her lips pursed.

Neville sighed, he had just coughed a dozen times and his throat was almost hoarse...... Rolf and Shirley whispered, not even hearing his reminders.

Rove quickly restrained his smile, turned around, and sat upright, "Professor McGonagall, we were just discussing human transfiguration."

Shirley nodded weakly.

Professor McGonagall glared at Rove fiercely, arching the jade cabbage she had worked so hard to cultivate, and now teaching her to lie.

Professor McGonagall picked up the boy's summer homework on the table, flipped through it, and after only a moment, she said:

"Mr. Scamander, this paper of yours on non-animal change is very mediocre.

The abstract is a little bloated, and the review doesn't mention the work of your predecessors, or where your innovations are......

「……」

Rove's scalp tingled, and he suddenly remembered that he had graduated from a bachelor's degree in his previous life, and the defense teacher asked him about the innovation of his thesis...... Is a four-legged chair turned into a three-legged innovation?

Professor McGonagall gives Rove a slap in the face, but in the end he gives O (excellent), much to Rove's utterance.

McGonagall was obviously able to find fault directly, but she also found a reason for the homework...... He cried to death.

The little wizards were also angry, and even such an excellent student as Scamander was criticized like this, and it seemed that Professor McGonagall was not in a good mood.

As the bell rang, Eloence Midgan returned to the classroom, her nose pinned up by Madam Pomfrey, just a little crooked, as if someone had punched her.

Everyone finally shifted their attention from Rove to her.

Professor McGonagall strode up to the podium and said with a serious expression:

"In the field of herbalism, there is a technique to graft the branches or shoots of one plant onto the stems or roots of another plant so that the two parts that are joined together grow into a complete plant...... Herbalists call it grafting."

"And in Transfiguration, there is also a way to 'graft' one object to another, which we call a transformation charm."

In this lesson, I'm going to lead you through the Transformation Spell."
