Underground classroom, Potions class. Snape was standing in front of the lectern with his arms propped up, his eyes lowering and glancing down.

In his class, no one dared to speak, not even Slytherin students.

Most of the Slytherin students sat in the back, especially Malfoy's group, who sat in the back row of the classroom, and then looked at Harry and the others sitting in the first row, snickering constantly.

Ron thought to himself, "I'm stupid, I knew Malfoy was going to deliberately squeeze us under Snape's nose, and I didn't come to the classroom to grab a seat." Thinking about it, he pounded the table gently.

Harry sat next to him, staring blankly ahead, he didn't listen to what Snape had said, and now he had in his mind what he had seen last night.

Wood walked into the break room with the rest of the team, soaking wet, wet with rain and sweat, covered in mud, with no smile on their faces, only exhaustion.

How much he wanted to train with them, Wood and they were still waiting for him. But I still haven't learned the waterproof and moisture mantra, and it rains all the time in October in the UK, almost without stopping.

"Harry Potter!" A low roar interrupted his memory.

Hearing this, Hareton felt bad, and looked up in the direction of the voice, and saw Snape staring at him with a dark face.

"What have you been staring at my waist, is it true that my belt has a recipe for taking potions well?" Snape spoke slowly. The sneer of Malfoy and the others came from behind, just like Snape's praise.

It wasn't known if they were laughing at Harry or if they were laughing at the potion's name. After all, this potion is called delicious.

Harry panicked, and lowered his head and handed Ron a pain mask.

Ron could only pretend not to see Harry's eyes, and also kept his head down.

Seeing this, Harry could only bite the bullet and say, "Professor, I'm listening to you!" ”

Snape's face darkened a little more when he heard Harry's answer. A smile twisted into the corners of his mouth. "Oh, so tell me what I just said?!"

Hermione held her hands high in the air, her body tense and ready to jump like a spring at any moment.

Harry stiffened to his feet, bowed his head, and said, "You just said how to prepare the potion well!" ”

Nonsense, this lesson is all about this!

"And what did you hear?" Snape uttered the words almost through gritted teeth.

“…… How to configure! Harry's voice was quieter.

"That's enough, Potter! It's all nonsense! "Snape roared like an erupting volcano." You don't hear anything at all. Gryffindor buckles ten! You answer, Augustus. ”

Hearing this, Malfoy's group laughed louder in the back.

Yes?!

Before Linde could react, his head was still buried in the back of the book.

Obviously, he was still scolding Harry one second and deducting points, and the next second he was directly connected to him seamlessly. This made him a little confused.

But he quickly stood up.

"Forehead......," Lind thought to Snape's question, "Eat potions, it's a potion used in everyday life, and it's usually kept in the form of drops.

Its function is to make the food more delicious and the fragrance stronger, which can be regarded as a flavor enhancer.

If you take it directly, you will feel a thousand flavors explode in your mouth, and finally mix it with a strong pungent sour and bitter taste. ”

Snape walked past Harry and stepped down from the podium to Linde, "Very well, but how to make it?" After speaking, he didn't look back, and naturally yelled, "Potter, did I let you sit down?" ”

Lind glanced over to Harry, and saw his bent knee bounce up again.

Snape's class was like a siege. Harry, who was standing up, wanted to sit down, and Hermione, who was sitting, wanted to stand up.

Thinking about it, Linde's mouth didn't stop, "Three lacewings take the fat tail, and then grind the negative phlegm beans into minced ......"

Hermione couldn't hold back any longer, muttering quietly, "Wrong, wrong!" ”

Both Lindh and Snape looked towards Hermione, and it was only then that Lindh reacted.

The grinding into minced pieces is one of the methods of dealing with medicinal herbs learned in the book "The Half-Blood Prince".

When we need a herb to reduce its size so that it reacts quickly with the rest of the potion, the usual way to do this is to cut it into small pieces.

But Snape's method was much more efficient, grinding to the end.

So the way they now record the treatment of negative phlegm beans in their book is: cut them into small pieces.

"Granger, is there anything you can correct about Augustus?" Snape spoke, unceremoniously.

"It should be chopped into pieces, not ground into minced pieces." Hermione stood up and spoke loudly, speaking quickly.

Snape waved his robe and returned to the podium. "All sit down!" He had never taught anyone in his class those little tricks he had figured out.

And he dared to say that every Potions master asked them to come to class, and they would never teach their little tricks at will.

These tips may seem to only play a supporting role, but in the process of refining difficult potions, these tips can seriously affect the success or failure of potion refining.

As for Linde, he actually knew how to question books in the second grade, to trace back to the source to understand the role of these steps in the potions refining process, and then question and boldly improve them.

Very good!

Snape admired in his heart. Little did he know that this was something that Linde would only learn after he got his hands on his book. Otherwise, with Linde's own attitude towards the Potions class, even if his thinking is fine, it is impossible to accumulate so much experience to learn these tips.

Snape then looked around solemnly, waiting until the underground classroom could hear a needle drop before he spoke slowly.

"You two are right! Our approach to a herb stems from our needs. Because we want to negative phlegm bean juice and its flesh react quickly with the potion. So we use the diced method.

But when we are sure that we have control over the variables, whether it's slicing or grinding. These are all possible. With that, he looked at Hermione,

"Granger, the knowledge in the books is correct, but it's not the only one that's correct. At some point, we need to look at it dialectically, rather than insisting that what others say is wrong. ”

After speaking, he changed his words, "Augustus, since you said this way, then you can concoct this potion for me today according to your own method, if it fails......" Snape did not continue to say the rest of the words, but anyone could understand the ill-will in his tone.

"And you! Since you don't even listen to the class, Potter, I'm going to see if you can make it! After speaking, he looked around, "What are you still doing?" Do you want me to shout three or two at the beginning? ”

As soon as the words fell, the originally depressed classroom boiled in an instant, and the little wizards in groups of two began to move in a hurry.

Lind also stood up, looking down at his right hand, which he couldn't move at all, and then at Snape stiffly.

He did it on purpose, right? I'm just saying, I can't move my hands, how can I mix medicine!

With that, he looked at Jane, who didn't know what was going on.

Linde didn't know whether to trust her or not, and every Potions class was basically Linde who controlled the whole process by herself, and basically didn't need her to do it.

But now my right hand is useless, my left hand is not a dominant hand, it is difficult to do precise operation, I can only count on Jane.

He looked at Jane's dull face and tapped her shoulder with his only left hand.

"I have only one expectation

Don't explode! ”
