Harry Potter Reborn

"Quiet." Snape closed the classroom door and said coldly.

In fact, there was no need for him to order everyone to be quiet, because as soon as the class heard the door closing, they immediately became silent and all small movements stopped.

Professor Snape seemed to be in a state of rage. Anyone who dared to make a sound at this time would have opened his eyes and hit the muzzle of the gun.

In fact, when Snape shouted "Quiet", he didn't really want to clean up the class. He just hoped that some reckless person would just make some noise, so that he would have a reason to vent his anger.

However he was disappointed.

Snape walked towards the podium, and his footsteps could only be heard in the classroom. He looked at everyone and said with a cold face: "Before class, I think it is necessary to remind you that next June, you will participate in an important event.

It's time for the exam, and in that exam you will prove how much knowledge you have learned about the preparation and use of potions."

"Although there are several people in this class who are indeed mentally retarded, I still hope that you can all barely pass the .Ls exam, otherwise I will... be very angry."

This time his eyes focused on the faces of Naviron Simo, causing them to gasp in horror.

Snape suddenly changed his tone and said with a smile: "Of course, after this year, many of you will not have the chance to take my class again, because many people think that passing the Ls Potion

The exam is worth cheering for you. There will be no greater pursuits. It doesn't matter. It's a smart person's way to quit when faced with difficulties. Next year, I will only select the best students to enter my potions class. Even if I want to

There may not be a chance in Shangdu."

Although it was full of irony, as soon as he finished speaking, there was a sigh of relief in the class.

Everyone's thoughts are: Oh, great, Merlin, I finally have to say goodbye to the Potions class... Ls? What's wrong with me, I have to continue to find Snape to be tortured.

Snape looked at the smiles that could not be concealed on the faces of most of the people in the class. His face was gloomy and the corners of his mouth twitched. He couldn't help but curse in a low voice: "Mad..."

Snape suddenly laughed, of course it was the kind of smile that resembles a tiger's smile but a cold viper's. He squinted his eyes and scanned the class: "Before the happy moment of farewell arrives, we still need to persist for one more year, just one year.

…”

At this moment, Snape made up his mind that this year, he would let them taste the pain for five years.

The students in the class suddenly shuddered.

Snape said: "Okay, let's start class. Today, we are going to prepare a potion that often appears in ordinary wizard level exams: demulcent. Its function is to calm and relieve irritability and anxiety. Note: If you add ingredients

When taking the medicine carelessly, it will cause the person taking the medicine to fall into a deadly, sometimes even irreversible lethargy..."

As soon as class arrived, Hermione was extremely energetic, with an expression of concentration on her face.

Harry didn't even look at the ingredients and preparation methods that appeared on the blackboard when Snape waved his wand. Instead, he took out a book called "Advanced Potion Making" and began to study it carefully.

This book is not a book that will be used this school year.

Every page of the textbook is filled with dense annotations, and some ingredients of some medicines have been crossed out at the owner's discretion.

If some potion experts were to see it, they would probably think it was a child's scribbling without taking a closer look, because the production process of these potions will fail even if the slightest change is made, let alone such drastic changes.

Noticing Snape's eyes on him, Harry gave Snape a Lockhart smile and put the book in his hand up to cover his handsome face.

At the bottom of the back of the book, there are a few small words: "This book belongs to the Half-Blood Prince"

Arrogant, very arrogant.

Snape's blood surged with anger. He knew that Harry was definitely provoking him on purpose, but he couldn't do anything about it, because if he punished Harry for not paying attention to the class, Harry would definitely look innocent.

Make the perfect palliative, and then ask a weak question, Dear Professor Snape,

I've already learned it, so it's no problem to read some more advanced potion knowledge. He will be the one who won't be able to step down. Fortunately, Harry didn't know that he kept this book, otherwise Harry would be so proud.

Ah. Using his knowledge to solve the problems he assigned is the most disgusting thing.

Unfortunately, Snape thought what Harry made him think.

Snape thought that the identity of the Half-Blood Prince was a secret that no one could discover, but Harry already knew it all.

Snape was out of sight and simply stopped looking at Harry, otherwise he would be furious

"The required potions are in the storage cabinet. You have one and a half hours. Get started. Hand in your finished products at the end of class and I will grade them for you." After Snape finished speaking, he left the underground classroom directly.

The classroom suddenly became buzzing.

"Why is Professor Snape gone?"

"Isn't that better? Come on, who knows how to do it? Teach me."

"Who knows how to make a head? It's not the first time. And my crucible isn't hot yet, so let me teach you."

Hermione took two potions from the cupboard, one for Harry.

The difficulty of the demulcent drug is not high, but its steps are very complicated, but the book is very detailed. If you can strictly follow the steps in the book, you can succeed 90% of the time.

However, everyone knows this, but failure is still a failure, because if you are not careful, you will forget or take a wrong step.

Everyone used their wands to raise a flame under the crucible, and then added various amounts of pre-measured potions into the crucible in strict order.

One thing that needs to be mentioned is that in July this year, the Ministry of Magic issued a legal provision "On the Trial Implementation of the Innovation and Replacement of Certain Instruments in the Magic Potion Industry". It is officially endorsed and requires that the field of potions must gradually learn from Muggles, starting with the tools.

Change.

Nowadays, the old-fashioned bronze, silver, and gold balances are almost no longer seen in Diagon Alley. They are replaced by electronic analytical balances used in chemistry laboratories in the Muggle world.

Precise measuring range, easy to use, improve pharmaceutical efficiency.

The students just used Muggle technology when weighing the potions.

I have to say, that scene was quite weird.

…

Each time you add an ingredient, stir the mixture for the specified number of times, no more or less, first clockwise, then counterclockwise, until the changes described in the book appear in the crucible, and then proceed to the next step quickly, a few seconds earlier

Or if you are a few seconds slower, you may make a mistake.

After the crucible boils, magic must be used to accurately control the temperature of the flame within a specific range, neither high nor low, and maintain it for a long period of time before adding the last ingredient.

Many students made several mistakes in the early stages, and then they quickly used 'Clean Up' to clean the crucible and start over.

When they find that the time left is no longer enough to support them from scratch, they can only bite the bullet and continue, no matter what happens, they have something to hand over first.

"Hey, Malfoy, you need to add ten grams of Silvermoon hay powder, but I see your small pile, you must have poured in a hundred grams."

"How...how is it possible? You must have seen it wrong. Continue to argue."

"Thomas, why did you suddenly jump to the seventh step? We were just on the fifth step. Didn't you see the sixth step?"

"Haha, that's nonsense. That's because the book is wrong. There's an extra step printed on the book. Trust me, it's absolutely correct."

"Okay, okay..."

Harry and Hermione were two exceptions. One of them looked relaxed and the other looked serious, and they continued without making any mistakes.

At fifty minutes, they stopped.

In the crucible in front of them was a uniform concentration of medicine exuding little bits of silver light, which was slowly rotating, like a shrinking Milky Way.

Needless to say, everyone understood that they succeeded.

It was so sour in their hearts that they lamented silently: There are lemon fruits on the lemon tree, but I am the only one under the lemon tree.

After a while, what attracted Snape in was an explosion.

Neville's Cauldron exploded again and again.
