A certain Hogwarts wizard

There are still 5 minutes left before class starts, and the seats in the classroom are already full as students come in one after another.

Perhaps every new student has inquired about some information about every professor at yesterday's party. Professor Snape can be said to be the most difficult professor to mess with in the eyes of students from the other three houses except Slytherin House.

So even though Professor Snape had not yet entered the classroom, the classroom seemed very quiet, and no student dared to speak loudly.

At nine o'clock on time, the students sitting at the back were startled by a "bang". Snape's classroom door suddenly opened and walked in. He wore a black robe that he never changed all year round and strode to the front of the podium. , an iceberg face that has remained unchanged for thousands of years looks very eerie under the candlelight in the classroom.

Snape glanced at the new students in the classroom with his deep black pupils, picked up the roll call roll on the podium and began to call names. After the roll call was completed, he put the roll call roll back on the podium and said in a calm tone, "Very well, it seems there are no idiots like Gryffindor who are always late. You all understand the importance of being on time."

Snape waved his wand and lowered the visors on the windows, making the entire classroom darker. Then he scanned the faces of each student.

"You are here to learn the precise science and art of potion preparation," Professor Snape said, his voice barely above a whisper, but everyone heard every word he said. One word.

"Since there's no silly waving of wands here, many of you won't believe this is magic. I don't expect you to truly appreciate the beauty of a simmering cauldron with white smoke and fragrant aromas wafting out. You don’t really understand the magical power of the liquid that flows into people’s veins, which makes people’s hearts ecstasy and their wills confused.”

Professor Snape's tone suddenly increased, "I can teach you how to increase your reputation, brew glory, and even prevent death - but there must be one thing, that is, you must not be the stupid fools I often encounter."

As Cornette listened to this classic opening statement, he noticed that the students in the entire classroom became serious. There is no doubt that Professor Snape has his own unique insights on how to control students' psychology.

"Then, let's take a look." Professor Snape said slowly in a drawling tone. He picked up the roll call and looked through it.

"Mr. Justin Finch-Fletchley of Hufflepuff, what is the function of bezoar?" He looked at Justin with empty eyes.

Justin's face turned pale as he stood up, and he said tremblingly, "I don't understand, Professor."

"It seems, Mr. Finch-Fletchley, that Potions class isn't worthy of your serious attention, is it?" Professor Snape said with a sarcastic smile on his face.

"No, no, professor, I just, just..." Justin stammered.

"Sit down! Next, Mr. Cornette White of Ravenclaw, do you know?" Snape glared at him with cold, empty eyes, and then continued to find someone to ask questions.

"Bezoars have detoxifying properties, professor." Cornette was stunned for a moment, then stood up and replied.

"Then where should we look for bezoars?" Professor Snape continued to ask.

"Bezoars are stones found in the stomachs of cows. They can be found in the stomachs of cows." Cornette replied calmly.

"What's the difference between the boat-shaped aconite and the wolf poison aconite?"

"Both are Aconitum, there is no difference, Professor."

"What potion can be made from wormwood and bezoar?"

"An overdose of sleeping pills."

"Sit down, Mr. White." Professor Snape stared at Cornette for a while before closing the roster with an expressionless expression.

Professor Snape looked at the students who had picked up their quills and were taking notes. After they stopped writing, he glanced around coldly, turned around and wrote on the blackboard a method of boiling to treat scabies.

Snape used his unchanging tone to explain in detail some of the common mistakes in the cooking process, and then asked the students to go to the material area at the back of the classroom to get a few snake fangs and a handful of bundled stems. Stinging nettle, a small jar of slugs with tentacles, plus a few porcupine quills and other materials.

"Now, let's start."

"It seems that you have already divided yourself into groups. The steps are on the blackboard. I hope you are not as brainy as a troll and can't even boil such a simple potion."

Snape dragged his long black cloak around the classroom, staring closely at the Hufflepuff badgers who were busy processing the materials, while the Ravenclaw students finished taking the materials. Look carefully at the notes you just took before starting to work on the material.

Cornette formed a team with Kevin Nkwisl. He had brewed a pot of scabies potion before the start of school and already knew how to make a good potion.

He first took out the venomous snake fang, put it into a grinder, and slowly ground it into powder.

"Kevin, you first steam four slugs with tentacles." Cornette said to Kevin while crushing them.

Kevin nodded, used tweezers to pick out four slugs with tentacles, put them into a crucible filled with water, lit the flame under the crucible, and slowly simmered them over a slow fire.

Professor Snape, who was always walking around Hufflepuff, kept the little badgers in a hurry during the cooking process, and Professor Snape sneered at the students.

Such as: "Fill the water so full, do you want to make a pot of slug soup..." "Crush the venomous snake teeth into powder, your eyes can't read it, tell me, are these lumps called powder?" ..." "I can't even weigh myself, even if there is a toad on the scale, I can do better than you..."

Among them, Justin, who couldn't answer the question, was the worst. Snape stared at him closely, and when he made a mistake in his steps, he would mock him.

Cornette put the crushed snake tooth powder aside and watched Kevin grab a handful of dried nettles and weigh them. He took the dried nettles that Kevin weighed and cut them into powder.

"Kevin, use your wand to slowly draw circles on the crucible to fully heat the slug," Cornette said.

Cornette stared at the slug's heat. When he poked it gently with a wooden stick and the slug became soft, he quickly turned off the heat and fished the slug out.

Kevin picked up the crucible, poured out the water inside, replaced it with clean water, and continued to simmer it over a slow fire.

Cornette poured the ground viper fang powder into the crucible, and kept stirring it with his right hand. When the liquid in the crucible slowly turned dark blue, he added the slugs to the crucible.

After a while, the liquid in the pot gradually turned from dark blue to red. Kevin took the powder of dried nettles and slowly sprinkled it, and the liquid gradually turned pink.

"Very good. Next, remember to turn off the heat, take down the crucible, and then add the porcupine quills." Cornette waved his wand to extinguish the flames and asked Kevin to take down the crucible.

Cornette put two porcupine quills into the pot and stirred three times clockwise. The unknown liquid in the pot turned a perfect blue color.

Finally, the potion was completed by waving the wand over the cauldron.

Kevin took out a transparent glass container from the table, slowly poured the potion in the pot into the container, and then breathed out slowly, "It looks like it was successful? Cornette, this color is similar to "Magic Potion" It’s basically consistent with the description in Potion.”

"Yes, Kevin, it's actually very easy. You just need to follow the steps explained by Professor Snape. It will basically not fail." Cornit answered as he held a bottle of potion in front of his eyes and looked at it.

After Cornette completed the potion, he began to help several roommates around him. When it came to the final step, he would always remind them to turn off the fire before adding porcupine quills to avoid making mistakes in the last step.

Professor Snape walked over to Ravenclaw. The calm eaglets were meticulous in handling the materials and strictly followed the steps on the blackboard. This made Professor Snape unable to make any big mistakes.

"Mr. White, it seems that you have finished making the potion. Let me take a look." Snape walked to Cornette and saw him reminding his roommate, and said.

Kevin, who was sitting next to him, quickly picked up the potion on the table and handed it to Professor Snape. Snape took it in his hand and looked at it carefully. "It's not bad. The quality is considered to be excellent. It seems that you have brewed it before." This is the medicine."

"Yes, Professor, I have cooked it myself before at home, but the methods in the book are not as good as those taught by you. I think some of your techniques are better in the refining just now." Kony Te replied politely.

Snape put down the potion in his hand, stared at Cornette with his deep eyes, twitched the corners of his mouth as if he was smiling, and said an inaudible word, "I'll come to my office after dinner."
