Swelling Solution and Engorgement Charm

Upon hearing Neville's words, Fred and George covered their faces, looking as if they were about to cry.

"So it was a secret between the four of you. We probably shouldn't have been in the Mystic Corridor; we should have gone back into the wooden barrel."

"Which barrel?" Hanna asked, somewhat bewildered. "Prefect Truman told us... that we can't use barrels unless we're Hufflepuff House students."

"I think Fred and George were referring to..." Wizet pointed towards the wall, "Those barrels."

Neville scratched his head in confusion and asked, "But isn't it still in the Mystic Corridor?"

"Yes!" Hanna chimed in, "It's the barrel in the Mystic Corridor. I thought it was the barrel at Hufflepuff."

Wizet and Luna burst into laughter, and even the Weasley twins couldn't keep up the act anymore.

"Why aren't you comforting us!" Fred protested. "Are you trying to sabotage us?"

"Yes!" George nodded as well. "Neville! We're from the same house, how could you say something like that?"

"This is a new secret, do you want to hear it?" Wizet asked. "Is it... a refinement of the previous secret?"

George gave a thumbs up. "Wizet has the best voice!"

Fred leaned closer and said, "Yes! Tell us quickly!"

"Where shall we begin?" Wizet turned to a new page in her notebook. "Let's start with our hobbies... and then extend to our strengths in magic!"

"Let me start by talking about the magical subjects you are good at... Neville and Hanna are both good at Herbology, but their focuses are different..."

"Neville is good at cultivating Magical Plants, while Hanna is more interested in the properties of various herbs, am I right?"

Blushing, Neville waved his hands and stammered, "Actually, it's not that I'm good at it... it's just digging and fertilizing... anyone can do that..."

"I don't know much either..." Hanna explained shyly, "I've just read some things since I was little... and they just happen to come in handy..."

Luna smiled and said, "Professor Sprout praised you all the time when we went to help out at the greenhouse recently!"

"Yes!" Fred nodded. "When we went to the greenhouse recently, Professor Sprout also mentioned you, asking why we couldn't be like you..."

"Is that the same thing?" George raised an eyebrow. "We were looking for something, and then Professor Sprout caught us..."

"Cough cough!" Fred coughed repeatedly. "George, now is not the time to use the 'nitpicking method'!"

"Oh...right!" George realized. "But now...I think I understand Snape's feelings a little better."

"Next up are Fred and George ..." Wizet steered the conversation back on track. "You two are not only skilled in spells, but also in Magical Creature Studies, and you've even taught yourselves Alchemy, right?"

"Wow, we're good at so many magical subjects! Clap!" Fred and George clapped with great confidence, grinning from ear to ear.

George clapped and nodded, "As expected, it has to be Wizet, he has an eye for our strengths!"

Fred added, "Oh, by the way! Once we successfully breed the Miniature Pygmy Puff, we'll send you a few as pets!"

"Since there are subjects you're good at, there are subjects you're not so good at, for example..." Wizet looked at Fred and the others.

Whether it was Fred and George, or Neville and Hanna, they all shouted the same answer.

Potions!

The sound echoed throughout the entire Mystic Corridor.

"Then let's take Potions from Potions as an example." Wizet raised his wand and waved it toward the storage cabinet in the corner.

A cauldron and a set of Potion Ingredients flew out of the storage cabinet and landed smoothly in front of Wizet.

"Potions Class!" Fred stroked his chin. "Shouldn't we... change our name?"

"If you ask me!" George said, winking, "I actually think calling someone 'teacher' is pretty good..."

Luna beamed and said, "I think it's a good idea!"

"Alright, alright! Luna has no objections either," Fred and George chimed in. "Let's call her that!"

"Ahem! Let's get back to the main topic!" Wizet coughed lightly, reaching out to pick up the Potion Ingredients. "Tell me what this is? What happens if you get pricked by it?"

Neville said, "Nettle."

In response to the second question, Hanna said, "If I get pricked... my skin will swell up and I'll feel a stinging sensation."

"We need two more materials..." Wizet waved her wand again, and several more materials flew onto the table.

Three of the jars contained a grayish liquid in which eyeballs were soaking;

The other jar contained a red liquid, and it was impossible to see what was soaking in it.

Wizet pointed to the four jars and asked, "And what are these?"

Fred leaned in so close, his nose almost touching the jar, and they stared at each other intently. "The eyeballs... they look like fish eyeballs..."

George picked up another jar, and as he unscrewed it, a faint smell of blood wafted out. "It should be some kind of internal organ?"

Luna looked at Fred and the others, smiled but didn't say anything.

"This is a Potion Ingredients we've studied before." Wizet nodded, pointing to the jars. "These are three portions of pufferfish eyes... and this is bat spleen..."

Neville and the others realized, "Swelling Solution!"

Neville answered the fastest, perhaps because during the previous school year, when he and Seamus Finnigan were brewing Swelling Solution, the cauldron suddenly exploded;

If Snape hadn't been standing by and pointing fingers, the explosion would likely have affected many people.

Nevertheless, he and Seamus Finnigan still lost fifty points in that class.

"There's another spell... We're in the same school year..." Wizet raised her wand, drew a circle downwards, and then gently flicked it upwards, "Engorgio!"

A beam of blue light shot from the tip of the wand and flew straight toward a wooden barrel beside it, which quickly doubled in size.

"Finite Incantatem!" The barrel returned to its original state, and Wizet put away her wand. "The Engorgement Charm, a spell with an effect similar to the Swelling Solution. Are there any key points regarding the casting technique?"

This was a magic subject that Fred and George excelled at, and George immediately said, "First, we need to understand the middle part of the spell, 'gor,' which means 'expansion' and 'filling.'"

Fred added, "Also, when chanting the mantra, the overall stress pattern is: unstressed 'en', then stressed 'GOR', and then unstressed 'geeoh', with the 'oh' sound being pronounced very lightly."

"Next comes the more complete secret..." Wizet snapped his fingers, and a cluster of flames appeared at the bottom of the crucible.

"Let's take a look at... what kind of connection exists between Charms, Herbology, and Potions..."

Hearing Wizet's words, Fred and George stopped joking around, their expressions becoming much more subdued than before...
