"Lightly Pull" in Charms

As her knowledge accumulated, Wizet developed new perspectives on the wonders of the magical world.

Like a "Otherworld" containing human wisdom, it may be a "gift" left by the pioneers, allowing later generations to more easily cast spells;

Similar ideas and research directions can often be combined and integrated to form a brilliant cluster, providing more possibilities for a wide variety of magic.

The pioneers transformed their research findings into brilliant star clusters, which evolved into sophisticated Potions, spells, Alchemy, providing convenience for those who followed.

Even if later generations do not understand all the principles, as long as they can unlock the "gifts" left by the pioneers, they can make them their own help.

Wizet traveled to the "Otherworld" more than once, and successfully transformed what she had learned, understood, and felt into Stardust, leaving it in the "Otherworld";

It was precisely because of his extensive contact with the "Otherworld" that he regarded the wisdom left by the pioneers as a "gift".

The star clusters do not exist independently; they reflect and influence each other within the larger context of the "Otherworld," and are interconnected. This is what Wizet wanted to tell Neville and the others.

However, the concept of "the Otherworld" and related ideas may be difficult to understand if one has not actually seen it.

Furthermore, since everyone's "Otherworld" seems to be different, it makes the description even more difficult, so a different way of saying it is needed.

"Water from the Fountain!" Wizet pointed his wand at the cauldron and cast Water-Making Spell to pour pure water into it.

He gently beckoned with his finger, and the flames, as if possessing a life of their own, spread across the bottom of the crucible, as if supporting the crucible and heating it.

"Cool!" Fred and George whistled.

Wizet looked at the Weasley twins and thought of a good way to put it, "The connection between Charms, Herbology and Potions is actually a bit like Magical Fireworks."

Neville and Hanna repeated, somewhat puzzled, "Magical Fireworks?"

Fred and George's eyes lit up, as if they understood what Wizet was trying to say.

"Ahem! Let Teacher George explain!" George coughed lightly, puffed out his chest, and said, "Making Magical Fireworks isn't a simple matter!"

"For example, how to add magic spells... how to adjust the proportions according to the initial recipe to achieve the desired effect..."

When talking about what he's best at, he rattled off a whole bunch of things, sharing some of the events that happened during that time.

"Mr. Fred, would like to add a few words!" Fred also straightened his back, "But to ignite the Magical Fireworks, all you need is a gentle pull..."

"Or like Dr. Filibuster's self-igniting, Bloom in Water magical fireworks..." he said, catching his breath, "You just need to spit on them to light them."

The two then looked at Wizet and said, "So, what do you think? We're not wrong, are we?"

Neville and Hanna were still somewhat bewildered, and looked at Wizet with a mixture of understanding and confusion.

"That's it!" Wizet. "Fred and George have put in a lot of effort to make Magical Fireworks so simple and easy to use."

"What would happen if we tried to break down the Magical Fireworks and treat them as subjects of magic?"

He looked at Neville and Hanna, "What magical discipline do you think those materials used in the production process belong to?"

Sensing Wizet's gaze, Neville nodded and tentatively whispered, "Herbology?"

"That's right!" Wizet. "So, what's the process of making Magical Fireworks?"

Fred and George answered in unison, "Of course, it's complex Potions!"

"The process of elimination..." Wizet continued, "The final 'gentle pull' or 'spit' to light the fireworks is Charms."

"Next question... Magical Fireworks are so complicated to make, yet so simple to use. What is their common purpose?"

Hanna spoke up, "Was it... an explosion?"

Fred whistled. "Absolutely right! It's for the explosion, of course!"

George grinned. "Hanna, it seems you understand the allure of Magical Fireworks!"

Wizet picked up the jar containing dried Nettle. "Let's go back to the Swelling Solution and the Engorgement Charm... what's their common effect?"

Hanna tentatively asked, "Make the object... inflate?"

"Right?" Wizet. "Back in the Hospital Wing, I used the Tickling Charm as an example, hoping you'd recall some interesting things..."

"For example, a leaf tickling your leg will make it itchy... Is that something in common with the Tickling Charm? The situation hasn't changed yet, we still need to find commonalities..."

Wizet pointed back to the Potion Ingredients, "Let's take 'expansion' as a common thread and rethink why they can do this, based on what we already know..."

"First of all..." Wizet pointed to the Nettle and said, "Neville and Hanna have already given the answer."

"Next are pufferfish eyes..." He pointed to the jar containing pufferfish eyes, "Why would you use them in Swelling Solution?"

Fred's eyes lit up. "Because pufferfish also inflate!"

George looked at the last bat spleen and answered quickly, "The last spleen enhances the Potions's effects... In fact, using animal spleens usually has similar effects."

Neville and Hanna quickly replied, "We know that!"

After all, Snape had mentioned more than once during class. "The Potions's color is wrong! The effect is terrible! Why didn't you add the spleen? You all lose five points!"

"Let's address the most pressing issue first..." Wizet said with a smile, "The most common problem when facing Potions exams... is not having enough time to brew Potions, right?"

Neville and the others nodded in agreement.

"You should have confidence in the magical subjects you are good at..." Wizet said, pointing to the Nettle, "For example, through Herbology, you can shorten the time for processing materials and speed up the process of brewing Potions."

"Using Herbology?" Neville and Hanna frowned and pondered, following Wizet's words.

"The conventional method is to crush the Nettle and then add them to the crucible, right?" Wizet said. "Crushing Nettle takes a lot of time, so is there a better way?"

"You can pick off the leaves and then scrape off the outer layer of the stem!" Neville replied. "That's what Professor Sprout told me."

"Good method!" Wizet nodded, looking at the crucible that was about to boil. "Neville, you use this method to treat Nettle, I will use the method mentioned in the book."

George said with a wicked grin, "I love watching fights!"

Fred nodded. "Neville! This is your chance to beat Wizet!"

Neville waved his hands repeatedly, stammering, "I... I didn't mean to defeat anyone... but... I'm good at Herbology!"

He took a deep breath, put on his gloves, picked up a Nettle, nodded to Wizet, indicating that he was ready...
