The cold wind whipped up the sleet and crackled against the window panes, and the cold air that permeated the castle was like this, and as this cold current seeped into the castle, many students caught a cold.

If this cold snap had arrived a week earlier, the Quidditch match between Gryffindor and Slytherin would probably not have been so much of a mess.

Even in this weather, a Quidditch match will not be cancelled. As you can imagine, all the players will be shivering in this weather, and it is estimated that no one will have so much heart to make trouble.

In the cold corridor, three figures hurried in, they sneakily looked around, and after making sure that there was no one around, they quickly passed through the stone wall three times, pushed the wooden door that appeared on the wall, and entered.

As soon as I stepped into the door, a warm smell mixed with a faint milky fragrance greeted me. On the other side of the door was a bright, warm and comfortable room, with a thick carpet on the floor and a roaring fire burning in the fireplace.

By the fireplace, a familiar figure sat in an armchair, and a small round table in front of the man placed a steaming cup of milk tea.

"Aren't you sick?"

Fred looked at the ruddy-faced roommate in front of him, was stunned for a moment, and asked incomprehensibly.

"Well, just got Madam Pomfrey cured. ”

Albert, the former sick man, sat there, staring at the parchment in his hand, and said without raising his head, "Anyway, it doesn't matter if you can't get into the history of magic, just don't be too bad in the exam." ”

"Why wasn't I the one who was sick!" George was jealous of Albert's treatment, and he wanted to be sick and find an excuse to skip class.

To be honest, the history of magic is considered by all students to be the most boring course of all subjects, and Mr. Ghost Binns has probably lived too long, his thinking is very rigid, his lectures are super boring, and even the effect of hypnotization is always drowsy.

"You can study how to find a suitable excuse for yourself to legally skip class. Albert said without thinking.

"It's rare to hear that from your mouth!" Fred muttered, "what excuse do you think it's better not to tell me about diarrhea? ”

As Fred spoke, George pulled out the picture from his pocket that had been treated with a developer potion, revealing the black history of Marcus McLagan.

The three of them looked at the guy in the photo and couldn't help but laugh again.

"Aren't you afraid that Marcus McLagan will find out that you're doing something?" Albert was speechless for a moment, always with the right to make a fuss, do you want to make trouble like that?

"Oh, okay. Next time, I'll put it in a frame. Fred blinked. "Tell me what kind of potion is better to use to skip class, what are the good suggestions?"

"Make your stomach hurt?" Lee Jordan said of several symptoms of illness: "How about nausea, vomiting, diarrhea, nosebleeds, fever, cold?"

"No kidding, you've seen anyone who made themselves sick by skipping class. George shook his head and vetoed, he was not a ruthless person who even harmed himself for skipping class.

"Unless, it is possible to find an antidote that can quickly resolve the symptoms in a short period of time. Fred's eyes lit up as he spoke, and he took out his quill and jowed it down, "If I can do it, I think it will sell well." Hogwarts estimates that a large group of people will buy it. ”

"By the way, you almost forgot what you were going to say?"

"What's the matter?" Albert asked.

"Kenneth Toller is locked up by Filch!" Fred and George said in unison, "He was caught using a big egg in the school by Filch, and now that hapless egg is being ordered by Filch to use a mop to clean the hallway of the big dung bomb traces." ”

"You did that?" Albert raised an eyebrow, knowing why even on his knees.

"Of course, we've been practicing the Transfiguration Charm, and it's not easy to find out now. George secretly Kenneth Toller in a particularly pleasant mood.

"I think they might have guessed who did it. Albert reminded, "If he's careful enough." ”

"We don't think Kenneth Tollor has a brain like you. The twins weren't worried at all about finding out that they were doing something wrong.

"What are you doing?" asked Lee Jordan, staring at the silver parts on the table. He had been tempted to ask since the moment, and Lee Jordan felt that Albert seemed to be making some interesting magic props.

"A magic prop for self-defense, the effect is that it can stun others when they are defenseless. Albert was piecing together a three-tiered set, the shape of which really looked like a lighter, and with a slight push, it would open up, revealing a strange honeycomb cylinder that would be enlarged by the Traceless Stretching Charm to place the pickled mandrake roots.

Now, of course, this thing is just a shell.

Albert tried again, and after it didn't get jammed, he took the parts apart one by one and put them back in the box.

The dark magic item, which he called the Banshee's Howl, had yet to complete the final step, which was to place salted mandrake roots into the device. As long as it is determined that the device can contain and control the mandrake roots, it will be considered a successful and useful prop.

Of course, it is also very troublesome to use, you must bring earplugs for yourself in advance, otherwise you will be unlucky with yourself.

After all, the cries of the mandrake roots are indiscriminate attacks.

"Stun someone?" asked George, puzzled, "You can shoot a stun spell at someone." ”

"No, I call it the Banshee's Howl. ”

"You can't hide a banshee in there!" Lee Jordan joked.

"Almost. ”

"You're really going to hide the banshee in there. ”

"It's pretty much the same, it's to make other people faint through sound. ”

"When you've got it right, remember to give me a try. ”

"Are you sure?" Albert's expression suddenly became a little odd, "Well, I don't mind if you want to be the first to try." Originally, I was going to test its power myself, but since you're going to have the courage to sacrifice. ”

"Brave to sacrifice, there must be no danger!" said George, frightened by Albert's words.

"Probably not, at most it will leave you in a coma for a few hours. Albert said uncertainly.

"Your rhetoric makes me feel very unreliable, and I always feel that you have made something very dangerous. Fred muttered, "By the way, do you have any good advice on a potion for skipping class?"

"How about finding some medicine that causes stomach aches, nausea, vomiting, diarrhea, nosebleeds, fever, colds, and then detoxifying the symptoms?" Albert suggested.

"Are you convincing poison?"

All three were shocked by Albert's audacity, was this to skip class, and even wanted their lives?

"Of course it's to dilute the poison, you just want all kinds of symptoms. Albert stuffed the box into the shapeshifting lizard's leather pouch, ready to find an opportunity to create the Banshee's Howl.

"For example?"

"How do I know, you can check the herbology books yourself, there are a lot of dangerous plants in them, there are a lot of plants in the Hogwarts greenhouse, find the corresponding symptoms, find the antidote, and then you can try to make a truant potion yourself. ”

The twins looked at each other, wondering why they thought Albert made sense.

It's just that trying to do it wasn't as easy as it was said, which meant they needed to put a lot of effort into their herb classes and pesky potions classes.

Moreover, after the potion is made, it is not finished, they still need to test the efficacy of the potion, and the things they make must be eaten by themselves first, which feels a little creepy when you think about it.

"For the sake of dreams, for the sake of Garon, a little sacrifice is necessary. Albert patted them on the shoulders and said, "Close your eyes and think about it, you can make a lot of Galleons from it by then." ”
