The Hufflepuff table's breakfast was as lavish and abundant as ever, but in today's context, it seemed somewhat mediocre.

After a year of experimentation, the young wizards from the other three houses had finally found a reasonable planting ratio. While preserving the unique crops of their respective houses, they gradually filled in the gaps for normal staple crops, roughly achieving 70% to 80% similarity to Hufflepuff.

The remaining 20% consisted of specialty dishes based on the "local specialties" of the other three houses.

For example, Ravenclaw's avocado salad, Slytherin's durian pastry…

Okay, Gryffindor didn't have a dish based on a single ingredient; their main crop was still just one thing: potatoes.

With the opening of the Hogwarts "garden" free trade market, Gryffindor chose the simplest and most brutal method – potato trading.

Just like the story that happened in the former Soviet Union a few months ago, the Hogwarts crop currency mechanism completely turned into a "potato standard." Most of the dishes and plants in the school could be converted into corresponding "bean coin" price ranges, and Gryffindor, which controlled the largest potato production area in Hogwarts, was undoubtedly the standard "bean coin" printing factory. This was also the development policy jointly voted on by the Gryffindor students.

Even if the "bean coin" continued to depreciate, the Gryffindor students stubbornly continued to issue more "bean coins," directly challenging market pricing with production.

At first, Erina took a wait-and-see attitude, hoping that the cruel reality would awaken the little lions.

However, as the Gryffindor students continued to expand the scale of potato planting, the situation began to become subtle.

The potato reserves in the Hogwarts kitchen began to exceed consumption. Under incomplete market rules, the potatoes produced by the Gryffindor students could not be infinitely devalued. Before the "bean coin" depreciated to half the price of the outside world, the problem of potato backlog had already given an early warning.

Earlier, these backlogged potatoes could be transported to Russia, Ukraine, and other places through the Heavenly Mandate Group's channels.

However, due to the establishment of the "Magical Market Supervision Administration," the Heavenly Mandate Group, hoping to whitewash itself and become a legitimate enterprise, naturally correspondingly reduced its supply and expansion speed. Now, most of the sales have temporarily shifted to local farmers' distribution and agency, rather than continuing to dump potatoes on a large scale to suppress the market—not to mention that the monetary pillar of the new Russian bank is also potatoes; they have to control the "bean coin" volume.

Cheese accordion potatoes, beast claw potato cakes, fried potato balls, mashed potato baked beef mince, potato omelet…

The Hogwarts kitchen has launched at least a dozen potato-based dishes, providing them as basic supplies to the tables of each house.

In fact, this did have a little effect, even the Weasley family ate especially happily.

However, the consequence was that the next week's potato planting ushered in a new climax.

Most young wizards have simple ideas; they plant more of whatever tastes good.

And under such circumstances, after much consideration, the Hogwarts head chef had to use her last trump card.

"Then, please answer—"

Erina asked softly in a serious tone, while trying to protect the drink at hand.

"In this situation, who is racking her brains to maximize the value of potatoes and give them more variety, who has beauty that eclipses the moon, kindness like the Virgin Mary, and talent as clear and dazzling as the moon under the starry sky? That's right, it's me, the Hogwarts head chef."

"Um, so…"

Hermione nodded noncommittally, took out her wand, and tapped Erina's glass of clear "drink" lightly.

Bone-chilling cold air surged out quickly along her wand, instantly freezing the liquid in the cup into a hard lump of ice.

"Oh no! Granger, casting spells in the Great Hall will cost points—"

Erina's little face collapsed in an instant. She looked around, lowered her voice, and negotiated.

"Listen... it feels like water, looks like water, smells like water before you drink it, and its official name is also called 'Water of Life'—if you pretend you didn't see it, I can give you later... um, give everyone a small sip, how about it?"

"Justice never compromises, nor does it make multiple-choice questions."

Hermione raised her eyebrows, her bright hazel eyes staring at Erina, and said seriously, one word at a time.

"After breakfast, I will go and tell Professor Dumbledore—you secretly brewed high-proof spirits and tried to mix them into the meal as pure water. Hannah, you can still choose to act as a witness now, so you are bewitched and coerced..."

Hermione glanced at the somewhat hesitant Hannah, and then glanced at the stack of "magic" breath-freshening candies placed in an inconspicuous place on the table.

If Luna hadn't told her that there seemed to be something wrong with the drinks the other two Nanas were drinking, she would have almost been deceived by these two fellows.

"But Erina said that we are also tasting dishes... this is a new type of potato fermentation..."

Hannah cautiously defended, her voice getting smaller and smaller under Hermione's gaze.

"Well, but wasting food is definitely not allowed, right?"

Erina reached out and rubbed Hermione's cold little face, and said with a hippie smile.

"This is a product test before the official launch. I'll go and explain it to Professor Dumbledore myself later. Besides, you are also a member of Gryffindor House. Aren't you a little bit happy to hear that potatoes are no longer backlogged? I am also responsible for everyone's hard work."

"But you are not an adult yet, you can't drink alcohol—especially since you are coaxing Hannah, and us."

Hermione rolled her eyes at Erina, paused slightly for a few seconds, and said unhappily.

During the holiday some time ago, she, Hannah, and Luna were coaxed by this white-haired dumpling to drink a bottle of wine together.

Although due to their wizarding physiques, and the fact that everyone didn't drink much when divided up, everyone didn't have any strange reactions or actions other than being a little flushed, this taboo "adult behavior" still made Hermione and others feel quite guilty.

"Okay," Erina shrugged with some helplessness, "but didn't you take up the glass actively in the end, right? I'm actually hesitating whether to make the brewing method public directly, otherwise it would be too unfair to everyone in Gryffindor. Um, Luna, if I publish the potato brewing method directly in *A Bite of Hogwarts*, what do you think of this idea? The professors shouldn't be angry, right?"

"From the content point of view, you can publish whatever you want—"

Luna's silver-gray eyes swept over Erina, and she said softly in a floating voice.

"As for Professor Dumbledore's reaction, shouldn't you know better? But I guess it's not a big problem... after all, you've done so much 'preparatory work' before... Compared to Professor Dumbledore's troubles, Mr. Filch and the prefects will have more work to do..."

"The Leaky Cauldron can recycle self-brewed spirits from Hogwarts students at a low price." Hannah's voice suddenly interjected into the three's conversation.

Looking at her three best friends who were looking at her with surprise, Hannah spread her hands and explained cautiously.

"Magic can't conjure up spirits or food. Mom always complains that it would be nice if she could buy some cheap and good spirits. Anyway, those drunkards can't taste the difference after they get drunk. The potato wine produced here in Hogwarts must be safe—I just..."

"Hannah, you're a business genius! Speaking of which, I remember the Leaky Cauldron has branch plans, right?!"

Erina was stunned for half a second, then quickly held up Hannah's little face and kissed it.

The self-circulating market of Hogwarts students is approaching saturation, but outside the castle is still a vast and unconquered primitive market.

And for most students, and even Professor Dumbledore, the credibility of the Leaky Cauldron is obviously quite high. If this distributor channel can be opened up, then there will be no obstacles from production to sales for Hogwarts' self-brewed "vodka."

From raw material producers to processed product manufacturers, this is an evolutionary form that even Professor Dumbledore cannot stop.

More importantly, in addition to the original food and dish takeaways, Erina has found a new business opportunity.

The Hogwarts "House Garden" project is almost completely fixed. If the professors want to forcibly terminate the students' cultivation and take back the vegetable gardens, unless they can continue to supply and maintain the gardens, it will inevitably cause extremely strong backlash—and on this basis, if students can cultivate, harvest, and process by-products on school land for external circulation...

"Speaking of which, in the Room of Requirement... I remember there's a wine cellar, right?"

Erina said thoughtfully, a gleam of excitement flashing in her eyes.

The venue is there, the channels are there, the raw materials are there, and the technology is also there... Now the only question is when to start, and how to organize the words to tell Professor Dumbledore so that he can accept this kind of future in a relatively pleasant and relaxed state.

The courage and adventurous spirit of Gryffindor House are the sparks buried deep in the heart of every little lion.

With the spread of potato brewing and the taste of vodka, Erina is not worried about the choices of those little lions at all.

"It's time to expand and standardize the prefect team..."

Erina glanced at Hermione, who was hesitant to speak, and a sweet smile appeared on the corner of her mouth.

"And to increase manpower, there must be a suitable reason—Hermione, you're right, we should take the initiative to uphold justice and confiscate prohibited items, instead of knowingly breaking the law and secretly violating discipline. Let's go to the headmaster's office together after class to have it out! If that old man Dumbledore doesn't agree, we'll just act first and spread the method, he can't do anything to us..."

"Have it, have it out?! No, what I mean is..."

Hermione tried to organize her words, staring blankly at Erina, who was clearly a little abnormally excited.

The beginning was fine, but how did it suddenly become like this?

Wait! Binary re-architecture modification magic!

Hermione waved her wand and cast a small-range *Finite Incantatem* around her, her eyes suddenly fixed.

At some point, the wine she had frozen had quietly melted.

The vodka in the glass was almost finished, with only a little residue swaying at the bottom of the glass.

Erina burped softly, giving off a faint aroma of wine.

"Hic~"
