An Arrow to the Knee

"Um... Albert, I suddenly have a good idea."

As night fell, Fred, who was engrossed in his homework in the Gryffindor Common Room, suddenly looked up and spoke.

"What good idea?" Albert asked without looking up.

"I got an inspiration from Fat Lip Seasoning."

"Fat Lip Seasoning?" Albert was taken aback by the title and frowned slightly as he asked, "Aren't you working on your thesis on Freezing Charm?"

"Ahem, well... I meant Fat Tongue Candy." Fred picked up a Bertie Bott's Every Flavor Beans and popped it into his mouth, his eyes shining.

"Nothing new," Lee Jordan commented.

"Shut up and let me finish." Fred couldn't help but glare at Lee Jordan before continuing to explain, "Since you can add Swelling Solution, why can't it be Swelling Solution or expansion magic?"

"Expansion magic?"

Albert looked up at Fred. The simplest way was to add Swelling Solution to the candy, which would have a similar effect to swelling magic. However, he wasn't sure if such Potions existed. As for swelling magic? He felt that Fred and George were not capable of doing that at their current level, and even he didn't have a good idea for the time being.

"So, you want me to help you accomplish this?" Albert raised an eyebrow and asked in return.

Both of them were immediately a little embarrassed, which was clearly what they meant.

"You guys don't want to open Joke Shop, do you? If so, then figure it out yourselves and turn your ideas into reality. Otherwise, you'll never have your own Joke Shop," Albert reminded him. "After all, the funny items in Joke Shop need to be created by yourselves, right?"

"Oh, okay," Fred replied casually, sounding somewhat discouraged.

"Tell me your thoughts," George said, sounding quite interested.

A few minutes later, Albert said irritably, "Why not just say that after eating the candy, your whole body swells up into a balloon?"

"I think the tongue is more interesting." Fred opened his mouth wide, making a sticking-out-of-tongue and panting motion. "Ideally, the tongue would grow bigger and bigger."

Are you the devil?

"Stop spitting everywhere," Lee Jordan complained irritably. "I think turning into a balloon would be more interesting."

"Casting a spell directly is relatively simple, but turning it into candy would probably require Potions or other methods," Albert said. "Also, have you considered the dangers of these joke props?"

"Danger? Is it dangerous?" George clearly didn't think so. "Most adult wizards can easily undo the expansion spell."

"That's right, it's just a fun joke prop. As long as it doesn't end up in the Muggle World, there won't be any other problems," Fred chimed in.

Magic is undoubtedly dangerous to ordinary people. Even a simple prank can bring them disaster. For example, the Engorgement Charm can inflate a person's body, and without the help of magic, they would probably die. But for a wizard who knows magic, it may just be a funny joke.

At that moment, Albert suddenly understood why the Ministry of Magic prohibited underage wizards from using magic outside of schools.

If something bad happens, the Ministry of Magic will have to come and clean up the mess. If it gets too big of a commotion, it will be even more troublesome. In a wizard's family, the child's parents will naturally handle these problems themselves.

"You guys didn't make that thing, did you?" Angelina stared suspiciously at the group of men in front of her. Judging from their conversation, it was quite possible. And that guy was the most suspicious.

Angelina looked at Albert with suspicion, while he continued to peruse the thick book in his hands.

"By the way, did you know? The price of Anti-Swelling Potion on the black market has gone up again," Shanna suddenly changed the subject.

"The black market, damn it, why didn't I think of that!" Fred was quite annoyed that he hadn't thought of this way of making money when Shanna mentioned the Anti-Swelling Potion.

"Alright, I bet no one would dare drink the Anti-Swelling Potion you brewed." Shanna couldn't help but roll her eyes at Fred. "If it were Albert, it would be one thing, but with you, no one would dare buy it. What if they get poisoned?"

"My Potions are still pretty good," Fred immediately retorted.

"I seem to remember that you failed your Potions assignment last time and got put in solitary confinement by Professor Snape." Angelina, who was playing Wizard Card with Shanna, bluntly exposed Fred's lie.

"Could someone really get poisoned by using Anti-Swelling Potion?" Angelina was curious about the skill level required to turn Anti-Swelling Potion into poison. "If the Potions -making method is wrong, it can indeed turn into a pot of poison, Anti-Swelling Potion is no exception. Otherwise, Anti-Swelling Potion wouldn't be so popular in the Hogwarts black market." Albert wasn't too surprised. "Who knows, some unlucky soul might drink their own concocted Potions and get poisoned!"

"Shut up, stop talking nonsense!" George said.

"Ah, it's too late." Lee Jordan covered his face with his hands, looking like everything was over.

"What's wrong with you three?" Aylia asked, looking at the three of them with a puzzled expression.

"Don't you know that what Albert says is more accurate than his Prophecy?" Fred explained. "Especially the bad things he says, he's always right."

As it turns out, Albert's words were indeed toxic.

The following day, a third-year Hufflepuff student was admitted to the School Hospital after experiencing mild poisoning symptoms from using his own homemade Anti-Swelling Potion.

Upon hearing this, Snape was so angry that his nose almost twisted out of shape. Seeing that his student had been poisoned by the Potions he had brewed, he threatened to put the student in solitary confinement for a month after he recovered.

That idiot completely disgraced him.

"I told you so!" Fred said helplessly to the stunned Angelina, then prepared to continue studying the formula for the Anti-Swelling Potion agent. He had not given up the idea of making money by selling the Anti-Swelling Potion.

"I think you should start chanting 'Gryffindor Team will win' every day now," Angelina said to Albert in a serious tone.

I don't think you can win!

"Shut up, you bastard, don't say things like that!" George reached out and covered Albert's mouth, trying to make him swallow his words.

"If we really lose, it will definitely be Albert's fault." Fred said with a sorrowful expression.

"Alright, stop fooling around." Albert interrupted the group who were about to say something. "Give up. There's no shortage of Anti-Swelling Potion on the black market. Besides, even if you succeed, you won't make much money. Stop messing around."

"How much does a bottle of Anti-Swelling Potion cost?" Lee Jordan asked curiously.

"Three Sickle a bottle." Aylia answered them, pulling a glass bottle of anti- Anti-Swelling Potion from her pocket. "This stuff was really popular on the black market a while ago."

Ever since Madam Pomfrey revealed the secret of swollen Sausage Lips, many people carry a bottle of Anti-Swelling Potion with them in case they accidentally get it; nobody wants to be laughed at.

"Why does this mark look so familiar?" Lee Jordan stared at the AA mark on the bottle.

"AA?"

Everyone turned to look at Albert.

"Well, I made a big pot last time. I kept one bottle for myself, gave some away, and sold the rest," Albert said without hiding anything. Actually, he hadn't originally planned to sell the Anti-Swelling Potion. Later, he got swollen himself once, and after taking out the potion to reduce the swelling, someone asked him where he got it, and then... Albert casually set a price and sold the Anti-Swelling Potion to them.

Of course, the glass bottles used for the potion came from the Transfiguration and the Duplication Charm.

"Wow, come on, you're not going to tell us anything about the black market?"

Hogwarts has a black market where students occasionally trade contraband, such as items from Zonko's shop, illegal potions, or prank toys.

Of course, there are also books on Dark Magic, and occasionally people will ask for help to concoct some Brain Boosting Potion.

However, this potion is easily detected during exams, and Hogwarts produces a few unlucky individuals every year.
