Hogwarts Headmaster's Office.

Unbeknownst to anyone, Erina had gradually walked among the four house heads and Professor Dumbledore, systematically elaborating on the solutions she had devised, occasionally answering the professors' questions.

As the saying goes, everyone has their own expertise. Although the punishment proposed by Erina, as the head chef of Hogwarts' kitchen, sounded somewhat childish, the professors quickly approved of most of it with the girl's clear and logical explanation.

In fact, whether it was the "Potato-Based System" or "Self-Service Cooking," the content itself was not a big problem. Most of the time was spent filling in and modifying some gaps and unreasonable details.

Ten minutes later...

"So, that's basically it. Shouldn't be a big problem, right?"

Erina licked her slightly dry lips, looked around at the surrounding professors, and spread her hands to simply summarize.

"From now on, Hogwarts' vegetable garden and kitchen will implement a production filing system, with dual audits based on menus and dishes."

"At the same time, the original vegetable gardens of each house will uniformly add potatoes and several scarce designated crops. Potatoes will be used as the basic trading currency to exchange for dishes of varying difficulty, as well as to exchange crops with other houses."

In fact, even without this unexpected situation, Erina's plan would require a large amount of potatoes as a food reserve.

With the sudden collapse of the Bear, if there were only financial means on paper, besides harvesting some cold money, nothing substantial could be obtained.

More importantly, if she simply played the currency game and wanted to use the collapsing ruble exchange rate to profit, when the people growing on this land recovered decades later, they would be waiting to be liquidated.

In this regard, the later A'sans have countless painful lessons as negative examples.

Therefore, Erina had previously communicated with Grindelwald and Dumbledore, listing potatoes, which are most suitable for mass planting and preservation, as a secret weapon for the "Gringotts-Soviet Strategy."

If everything goes well, Hogwarts might be able to use a lot of potatoes to "buy" a group of Bear wizards and Bear scientists, not just people, technology, and materials, but also the more important hearts.

The mystery of the magical world, the benevolent social assistance, coupled with the huge funds scammed from Gringotts, whether facing pure academic researchers, idealists with noble ideals, or social people who need to enjoy life... Hogwarts can now offer them a price they absolutely cannot refuse.

"That potato exchange, I don't think there is much to worry about, after all, we can implement it while adjusting. This can promote exchanges between houses on the one hand, and on the other hand, it can better allow children to learn in labor."

Unsurprisingly, after hearing Erina mention the idea of mobilizing all students to plant potatoes, Albus Dumbledore quickly reacted, gave Erina a meaningful look, and took the initiative to express his support.

With Dumbledore's initiative, the other four house heads, although they still didn't quite understand what the "Potato-Based System" was, nodded in agreement - perhaps you wouldn't trust an economist too much, but you can always trust Albus Dumbledore.

Happy cooperation, as expected of her and Grindelwald's best partner.

"Then, let's start acting..."

The white-haired dumpling happily narrowed her eyes, clapped her hands, and was about to leave the headmaster's office to start preparing dinner.

You know, Erina had been coveting Professor Sprout's little darlings in the greenhouse for more than a day or two. Now that she had a reasonable excuse, she naturally had to think carefully about how to cook them.

"However..."

Just then, Dumbledore's unhurried voice suddenly came from her ear.

"Regarding what Miss Kaslana said earlier, that Hogwarts' kitchen will suspend service tonight, I think it's still a bit inappropriate. Hogwarts has never had such a precedent, and we cannot punish too many people for the mistakes of a few."

Eh?! Erina raised her eyebrows and looked at Dumbledore strangely, wondering what kind of calculations this white-bearded old radish was making in his heart.

"Trust me, you can't deprive a house-elf of their willingness to work, it's not a good thing for them. Once they receive the news that the kitchen is closed at night, I guess those hardworking house-elves might mistakenly believe that Hogwarts is going to collectively dismiss them, and thus fall into great panic and anxiety. And—"

Dumbledore thought carefully, looked at Erina who was deep in thought, and winked playfully.

"If I remember correctly, the students' vegetable garden mainly takes care of fruits and vegetables, and there seems to be no reason to cancel the basic meat supply? After all, we can't cancel meat dishes just because the vegetable garden was stolen. Also, if possible, let go of Professor Sprout's plants, and the little animals in the Forbidden Forest..."

Eh, eh, eh?! Seeing the smile on Erina's face disappear instantly, Dumbledore couldn't help but breathe a sigh of relief - sure enough, he guessed it, he almost had to eat something strange tonight.

There is no doubt that Hogwarts' kitchen is not Erina's one-man show.

Therefore, Albus Dumbledore believed that it was still necessary to remind this little witch at this time that she, as the head chef of Hogwarts, should provide quality three meals a day for all teachers and students, rather than using it as a threat.

"Professor Dumbledore is right, Miss Kaslana, I think the students can still eat meat."

Professor McGonagall nodded in agreement. In her opinion, this was not just for the students of Hogwarts.

If the kitchen was closed tonight, then the provision of meat dishes at the staff table would all depend on Severus Snape and Erina Kaslana.

Not to mention that she had never witnessed their cooking skills in person, Professor McGonagall was still a little worried.

More importantly, judging from Erina's vague appearance, Professor McGonagall faintly had a bad feeling in her heart.

She always felt that the ingredients in this little witch's mouth were not common daily ingredients - and Dumbledore's subsequent suggestion directly confirmed her idea that this child actually wanted to secretly cook magical plants?!

"Well, I also think Dumbledore makes sense, meat still has to be eaten."

"That's right, and Hufflepuff students were forced to fight back, and it's too much to let so many innocent students not be able to eat meat - also, those magical plants in the greenhouse can't be eaten, I still have to teach classes later."

Then, Professor Sprout and Professor Flitwick also nodded in agreement.

Especially the Herbology professor, who gradually reacted, now looked at Erina with a rare serious tone and advised her, decisively dispelling a certain little guy's coveting of those poor plants - if Dumbledore hadn't reminded her, she almost didn't react to why Erina needed her cooperation when preparing dinner ingredients.

Hmm... ruined the vegetable garden, and still want to eat meat?!

Erina raised her eyebrows and glanced at the professors present.

In the end, the reason why this happened, in addition to the students' initiative to cause trouble, the long-term inaction and muddling through of the Hogwarts teaching staff was also a very important reason.

Therefore, in the initial punishment measures, Erina was indeed targeting not only the little wizards of the four houses who caused trouble, but also the entire teaching staff of Hogwarts School of Witchcraft and Wizardry, who were also within the scope of punishment.

If Dumbledore and McGonagall didn't mention this, it would just be a matter of eating a few less pieces of meat, and it would be over.

However, since the professors have now reached a unified meat-eating front, she can only think about leaving some deep memories for the whole school from other places.

These stupid Englishmen don't seem to understand that you should never offend a head chef who has the power to cook.

"No problem, then, let's eat fish tonight."

After Erina pondered for a few seconds, she looked around the office and showed a brilliant smile.

"Don't worry, the ingredients are those lively and lovely big blue fish in the Black Lake of Hogwarts, and the cooking method is the most authentic Scottish and English style. The taste will definitely satisfy everyone."
