On Thursday morning, William came to the underground potion class classroom. The double potion class for students from Slytherin and Gryffindor College were taken together. Today they are making a new potion: body shrinkage solution. One disadvantage of this potion is that you cannot change back before the effect is over, and it is body shrinkage solvent and cannot change the size of your clothes. Ron and Malfoy were both bickering in the same class, and William always felt that Pansy was secretly sending out a love affair with Malfoy.

Neville was in trouble at a few seats away from William. In potion class, Neville was always mentally broken; potion was the worst course he had learned, and because he was very afraid of Snape, things were ten times worse. His potion was supposed to be a bright green acidic substance, but it turned into - "Orange, Longbottom." Snape said, scooping out a little with a spoon and letting it splash back into the cauldron so that everyone could see it. "Orange. Tell me, child, has something penetrated into your thick skull? You didn't hear me say, clearly, just a drop of rat bile? Didn't I clearly say, is it enough to add a little leech juice? How do I tell you to understand, Longbottom?"

Na Cheng's face turned pink and the person was trembling. He seemed to be about to cry.

Hermione wants to speak, and William whispers, "Hermione, you are helping you out of your way."

Hermione knew that William was right, Snape's rule was that the more fearless you were, the more he became. Hermione looked at Neville helplessly and sympathetically.

"Longbaton, before get out of class is over today, we will feed your toad a few drops of this potion to see what will happen. Maybe doing this will encourage you to do this potion well." Snape walked away and came to William to check William's reagents. Snape was observing whether William's potion configuration had regressed in this class. William was very calm. He had no pressure and had elegant and skillful movements, which made Snape very satisfied.

Snape walked away, leaving Neville to be scared. "Help me!" he moaned to Hermione. Hermione gave him instructions from the corner of her mouth so that Snape would not see it.

get out of class was about to end, and Snape walked to Neville, who was cringing beside his cauldron. "Everyone came to his feet," said Snape, his dark eyes lit up, "Look at what will happen to Longbottom's toad. If he made a body-reducing potion, his toad would shrink into tadpoles. If he did something wrong, I have no doubt about this, and the toad would be poisoned and died of poisoning."

The students of the Gryffindor College looked at him in fear; the students of the Slytherin College looked excited. Snape held the toad Raffle in his left hand and placed a spoon into Neville's thorn, which was now green. He poured a few drops into Raffle's throat.

After a moment of silence, Laifu gasped; then with a gentle puff, Laifu twisted on Snape's palm.

The Gryffindor students clapped. Snape looked sour and pulled a small bottle out of his robe pocket, poured a few drops on Leff, and suddenly reappeared, completely an adult toad. "Gryffindor five points," Snape said, and this sentence wiped away the smiles on everyone's face. "I didn't ask you to help him, Miss Granger. Leave the get out of class."

"William, stay," said Snape, who was kept by Professor Snape.

William first helped Snape deal with the uncleaned experimental equipment

"Does these Gryffindors have no brains? I don't know how to clean the acidic solution." Snape was still sarcastic.

When everything is cleaned, William turns his head

"Professor, what's the matter with me?" William asked

"William, do you have anything to do every Wednesday night?" Snape asked

"No, Professor" William didn't know what Snape was going to do

"I'm configuring wolf poison recently and need an assistant," Snape said

"I'm happy to serve, professor" William said

"Then you go to my lab on time at 7:30 p.m. every Wednesday. The configuration of this potion will take two months to adjust your schedule," Snape said slowly.

"No problem professor" William said with a smile

William left without anything else.

Professor Snape needed an assistant to configure the wolf poison potion that suppressed werewolf deformation. The configuration of this potion was very complicated. William did not ask who the potion was for, and he knew this. William's silence on this question also made Snape admire him. In his opinion, William was a student who knew what to ask and what not to ask.

On the other hand, after class, Harry, Ron and Hermione climbed up the stairs to the vestibule.

Harry said to Ron, "Today Malfoy said I should go to Black for revenge. What kind of revenge does he have with me?"

"You believe his words, he hopes you do something wrong!" Ron said, "You said right, Hermione?"

Hermione did not answer. Ron looked around. "Where has she been?"

Harry turned around, too. Now they stood at the top of the stairs, watching the rest of the class walk by their side and head towards the hall for lunch. "She was just behind us." Ron said with a frown.

"She is there," said Harry. Hermione was gasping for a moment and hurriedly went up the stairs; she grabbed her schoolbag with one hand, and seemed to be stuffing something under the front of her robe with the other.

"How did you do this?" Ron asked.

"What?" said Hermione, walking with them.

"You were behind us a minute ago, and now you are forked under the stairs."

"What?" Hermione looked a little confused, "Oh-I have to go back and get things. Oh, no..."

Hermione's schoolbag had a crack. Harry was not surprised. He could see at least twelve large and heavy books in her schoolbag.

"Why do you carry so many books with you?" Ron asked her.

"You know how many classes I'm going to take," Hermione said breathlessly, "Can you help me bring some books?"

"Okay" Ron flipped the few books she handed him

"Thank you," said Hermione, who put all the books back into her own bag. "I hope there is something good for lunch, I'm starving to death." She added, and she strode towards the hall.

"Do you think Hermione didn't tell us something?" Ron asked Harry.

"I don't know if William knows Hermione is strange lately" Harry shrugged.
