International students at Hogwarts

Chapter 61 Snape's Chemistry Lesson

Lu Ren: w(Д)w
Professor Snape, why don't you play your cards according to the routine?
Take another look at the script!It clearly says that you should ask, "What will I get if I add daffodil root powder to a wormwood infusion?"

Harry's brain crashed as if he met a fresh meat star who could only talk one, two, three, four on the set.

What are you doing in the cauldron?It's not mentioned in this book!Harry hurriedly looked at Ron and Lu Ren, Ron was already looking dull, and Lu Ren couldn't tell him the correct answer through his eyes.

'It's over, I'm afraid no one can answer Professor Snape's question, not to mention wizarding families, even those children from Muggle families who receive a happy education can't answer it.When little wizards come to Hogwarts to go to school, they are at most 12 years old. This age may have just graduated from elementary school in the Central Plains. Can such a young child understand the operation of the chemistry laboratory? '

To his surprise, Hermione raised her hand.

Snape signaled her to be calm, and then continued to ask: "Don't you know? It seems that fame doesn't mean everything. Let me ask you another question. What should you guarantee when doing experiments with poisonous and foul-smelling gases?"

Harry & Ron & Lu Ren: Ah this...

Hermione still held her arms high.

"Miss Granger, I'm asking Mr. Potter a question! If you don't put your hand down, Gryffindor will randomly lose some points." Several students couldn't help laughing.

"It's only three things, I'll give you another chance. Before the experiment starts, what should we do with the instrument?" Snape stared into Harry's eyes, and Harry couldn't help looking away.

he does not know.

"Tsk tsk, what I just asked is common sense that Muggles should know. It is not a big problem to be raised by Muggles and be ignorant of the wizarding world, but Mr. Potter, your ignorance of Muggle knowledge is a big problem." I'm shocked. Did you preview your textbooks before term started? Did you really study hard in your Muggle school?" Snape folded his arms, watching Harry deflate, he was in a great mood.

"Miss Granger, please answer these three questions."

Hermione hesitated for a moment, but said: "You can't look down on the container, it's to prevent damage from splashing liquid droplets. For experiments with smelly or poisonous gases, ventilation should be ensured. Before the experiment starts, check whether the equipment is intact and whether the device is secure. "

Harry almost wanted to hide in a crack in the ground.

very good!all right!Snape felt that the little girl in front of him was much more pleasing to the eye.Looks like this little girl has a talent for Potions.Muggle-born, highly talented in Potions... Snape thought of a lot, and his expression was a little gloomy.

"Five points from Gryffindor—could have been ten."

"Professor, this kind of knowledge is not accessible to Muggles at the age of 11..." Lu Ren raised his hand, and after getting permission, he opened his mouth and explained to Snape.

"Sit down." Snape didn't want to entangle Lu Ren any more, so he directly asked Lu Ren to sit down, "Have you seen enough of the jokes? Why don't you write them down?"

Snape suddenly turned his attention to the other young wizards.There was a sudden noise in the classroom, and the little lions and little snakes all took out their quills and parchment, and wrote vigorously on them.

Snape looked at Hermione who was sitting next to Harry. He thought for a while, "Also, Miss Granger, you and Lu Ren should switch seats."

Hermione:? ?

Although she didn't understand, in order not to continue to irritate Snape, she honestly changed seats.

Thus, the seats of the four changed from Ron Harry Hermione Lu Ren to Ron Harry Lu Ren Hermione.

There was no reason why Snape did this, it was purely disgusting to see the Potters getting too close to Muggle-born girls who were good at potions.

After most of the young wizards stopped writing, Snape spoke again, "The question just now makes me suspect that most of you are the kind of stupid fools I often encounter. I hope you have the due respect for the experiment. It is unrealistic to have a correct understanding of the operation. I will write the safety operation rules of the laboratory on the blackboard, and you will write them down. I will conduct random checks next week. Those who have not memorized these rules, I guarantee that they will never forget them. "

With a wave of his wand, the blackboard drifted over, and he began to write on the blackboard: [-]. Before entering the laboratory...

[-]. Before the experiment begins...

……

[-]. Without permission, it is absolutely not allowed to mix various potion raw materials to avoid accidents.

"These ten rules are the iron law of Potions class in the future. Anyone who violates them will leave voluntarily." Snape said coldly.All the little wizards couldn't help speeding up the speed of copying.

"Lu Ren!" Snape raised his voice suddenly, "tell them the procedure and final product of adding the daffodil root to the wormwood infusion."

He decided to take out a model to demonstrate to the group of baby baboons, to let them know what real potions are.

"Professor, the combination of narcissus root powder and wormwood infusion can make the water of death, a powerful sleeping medicine.

The specific steps are to take the narcissus root, remove the impurities in the sample, then cut it into small pieces, put the chopped sample into a mortar, use a pestle to crush and grind the sample.Then prepare the wormwood extract, slowly add the ground sample into the extract, and stir carefully with a glass rod..."

Lu Ren roughly described the process of preparing the water of life and death. Although he didn't know much about the preparation of potions in the magic world, it was still okay to follow the previous chemical experiments.

"Mostly correct." Snape was quite satisfied. In the whole classroom, only Lu Ren and Hermione looked like wizards, and the others were simply baby baboons!Especially Potter, hopeless!

After the little wizards finished copying the laboratory rules, Snape began his explanation.

What Snape wants everyone to finish today is boil potion, which is a special medicine for treating pustules, measles, boils and other symptoms of lymphatic tuberculosis.The steps are not difficult, very suitable for newcomers, but careful operation is required.Making it incorrectly can cause this potion to have the opposite effect, creating boils instead of curing them.

The sign of the potion's success is also obvious: pink smoke will rise from the cauldron if brewed correctly.

However, Lu Ren feels that his style is simply a combination of chemistry class and cooking class.

"Weigh an ounce of dried nettles, then take a pair of snake's teeth and grind them. Heat the cauldron, pour the nettles into the roast, and when they smell bitter and pungent, take them out and set aside Standby. Put the slug in a pot under cold water. After the pot is opened, turn to low heat and cook for 5 minutes, remove and drain the water, and finally mix the three materials together and boil. After boiling, remove the crucible from the fire and put the porcupine spines in it. .”

Lu Ren: ...

Isn't this really a food show?
