Fast forward to the second week of December, and the recent period has been calm, and no one has been attacked.

There are petrified people and cats lying in the school hospital, silently proving to everyone that this calm is only temporary, in fact, it is a sign before the storm is coming.

On this day, Professor McGonagall came over as usual to collect the list of students who had stayed on campus for Christmas.

Dudley, Harry, Ron, and Hermione, all four of them signed the list.

Malfoy also stayed, which made Harry and Ron even more suspicious of him. It's a good thing to use a polyjuice decoction during the holiday season to bring out Malfoy's truth.

Dudley now shifted his suspicion back to Lockhart.

Because Lockhart has been very low-key lately, which is not in line with his personality at all, and he seems to be secretly planning something.

Hermione had already started to make the compound decoction, but it hadn't been boiled yet, and the ingredients were still lacking.

They also needed the horns of the bicorns and the skin of the African tree serpent, which could only be obtained in Snape's private pantry.

Dudley thought it would be easier to get these things done, and counting Ha 1 to 7, Snape's offices were easily broken into.

"We need to get the word out," Hermione said dryly, as Thursday afternoon's Potions class drew closer, "and one of the four of us needed cover before someone could sneak into Snape's office and get what we wanted." ”

Harry and Ron stared at the ground with humility, neither of them wanting to steal from Snape's office.

"I'm going to steal the materials from Snape's office," Hermione continued in a businesslike tone, "and you're going to make the class so chaotic that Snape has at least five minutes to get busy." ”

"I'd better go," Dudley said, he needed something, and it was only available in Snape's office.

He could use this opportunity to steal it together, "I'm going to be safer, and even if I get caught by Snape, it won't be fine." ”

Hermione was stunned for a moment, then quickly lowered her head, and no one saw her blushing.

She believed that Dudley had gone to Snape's office instead of her to protect her.

Saying that there will be nothing will definitely be false, and if you are caught doing this kind of thing, I am afraid that you will be expelled.

When she decided to steal, she was ready to be opened.

"That's it," Dudley decided when he saw that Hermione didn't react.

He didn't know what Hermione was thinking, and if he did, he would laugh at Hermione.

To tell the truth, he can be made up to 108,000 miles away, and he is the one who gave Snape a gift no matter how he says.

If he was caught red-handed by Snape, Dudley would certainly not have panicked in the slightest.

The only way to go unpunished is to betray Harry once more and give Snape his picture.

Dudley patted Harry on the shoulder and said with a smile, "It's up to you to do the rest." ”

Harry grinned to grin, deliberately causing trouble in Snape's Potions class, like stabbing a sleeping dragon in the eye, which was a very dangerous thing to do.

Soon Thursday afternoon arrived, and they went to the basement classroom to wait for Snape's arrival.

The furnishings in the classroom were still the same as usual, with twenty crucibles erected between the wooden tables, and copper scales and jars of ingredients on the tables.

It wasn't long before Snape arrived and classes began.

He succinctly explained the potion to be made today, and then asked the students to start brewing it.

The cauldrons on the tables were lit, and soon the classroom was filled with smoke.

Snape walked back and forth through the smoke, focusing on the Gryffindors, crudely criticizing their hands-on abilities.

Harry was particularly vicious, attracting more than half of Snape's firepower.

In every Potions class, you can hear Slytherin students snickering gloatingly.

Draco Malfoy provoked Harry consistently and unscrupulously, rolling his eyes at Harry with his pufferfish eyes.

Harry didn't even dare to give an eye for an eye in Potions class, and if he did, he would be immediately locked up by Snape, unable to even shout 'wronged'.

Dudley was preoccupied with two things, brewing potions while secretly watching Snape, waiting for an opportunity to make Harry mess with it.

Wait, wait, wait.

Snape finally stopped laughing at Harry's swelling potion for being too thin, and he turned to bully poor Neville.

Dudley immediately gave Harry a look and told him to quickly complete the job he was set out to do.

Harry nodded.

He quickly stooped behind the cauldron, pulled out a string of Fred's laborious fireworks from his pocket, and quickly lit it with his wand.

The fireworks began to hiss and burst out of the sparks.

Harry quickly got up, took aim at his target, and threw the fireworks out.

The fireworks fell into Goyle's crucible accurately.

Goyle's potion exploded, and he poured it on the class.

Everyone screamed under the attack of the splashing swollen potion.

Malfoy was caught off guard and was doused in the face, his nose inflated like a balloon.

Goyle covered his eyes with his hands and stumbled, his eyes swollen to the size of a lunch plate.

Snape desperately tried to silence everyone, to get to the bottom of what was going on.

In the midst of the chaos, Dudley slipped out of the classroom......

"Quiet!" Snape growled, "The students who were splashed with the potion came to me to get the swelling reducer. Wait until I figure out who did it......"

Dudley could hear Snape roaring outside the door, but there was no time for him to snicker.

He composed, and quickly ran towards Snape's office.

It has to be said that the collection in Snape's office is very large.

Dudley felt that this trip was really the right one, and the harvest was not bad.

With the principle that more is better than less, he simply took a few of the scarce materials.

It was also done to conceal what he was really stealing, so that Snape could not guess what potions the thief was trying to refine.

There are enough materials, and now there is still the most important thing missing, which is the ultimate purpose of Dudley's here.

Luckily, Snape did have a refining of this thing.

Now that the things had been obtained, Dudley had no reason to linger any longer, and he hurried back to the basement classroom.

At this time, the classroom gradually returned to order, everyone drank the antidote, and it didn't take long for all kinds of swelling to subside.

Snape finally had time to investigate what was going on, and he walked briskly to Goyle's cauldron and scooped out the black ashes of the fireworks twisted into twisted flowers with a spoon, and the classroom suddenly fell silent......
