Hiding in Hogwarts as a professor

Of course Twil was not a devil. After receiving the assurance from the Weasley twins, he picked up a canary biscuit with great interest.

From the outside, this biscuit is no different from the custard biscuits I usually eat.

However, he just glanced twice and noticed the doorway inside.

“A combination of magic and potions? I have to say that you are the most talented people I have ever seen in the field of pranks.”

Human body transformation is a very dangerous magic. It does not mean that you cannot try it, but many wizards are not sure whether they will be interfered by other magic after human body transformation.

This is where the danger of human body deformation lies – even if you can ensure that your deformation is safe, the chain effects produced when encountering other magic are something that this fragile magic cannot bear.

George chuckled and looked at each other proudly.

It is relatively safe to use magic potions to transform. As long as you control the dosage, and then use magic to control the amplification and transformation direction, you can avoid the side effects of simple transformation!

“We have been studying it for a long time, and have spent most of the last six months on this before we successfully completed it.”

“Furthermore,” Fred took over, “for safety’s sake, we also referred to the protective magic on your badge to improve the canary’s protective ability after transformation!”

“So, this is the reason why your academic performance has declined recently and why you removed my badge?”

Tver had no intention of pursuing them, he just shook the biscuits in his hand at them teasingly, and then stuffed them into his mouth under the surprised eyes of the students around him.

“It tastes good, with a lot of milky flavor, but it’s not crispy enough and a bit soft.”

But until he swallowed it completely, there was no sign of deformation.

The Weasley twins looked at this scene in surprise, watching as Tweel even picked up the second cookie and tasted it with slightly squinted eyes.

George picked up a cookie from the plate in disbelief and—

stuffed it into Fred’s open mouth in surprise.

“No…bang…”

Fred unsuspectingly turned into a chubby canary, flapping his fat wings and angrily pecking George’s arm with his short beak.

However, it didn’t take long for him to change back to his original shape. Only the feathers scattered on the ground proved what had just happened.

“It looks like the effect is good.” Tver looked at it with interest.

“But professor,” George said quickly, “why didn’t the cookies have an effect on you?”

“As long as I think about it, the magic you release will not work on me.” Tver explained in an evasive manner.

It can’t be said that he used black magic to dissolve the potion and magic in the cookies, right?

“However, you can configure and release potions and magic by yourself, but where do you get the biscuits themselves? I heard that you only sell canary biscuits for 7 Silver Sickles?”

When talking about their profession, George and Fred suddenly became serious, a hundred times more serious than usual.

“We purchased the biscuits from Ms. Margaery Mason, the saleswoman on the Hogwarts train. If it were before, plus the cost of potions, seven sikos would really not make much.”

At this point, George and Fred had smiles on their faces.

“But Ms. Mason said that wheat, milk and other things in the wizarding world are much cheaper now.”

“The price was even lower than what she would normally have cost to grow her own, so she bought the ingredients directly from the store to make the cookies.”

“So the price sold to us is also much lower!”

Seeing the two people’s happy expressions, Tver knew that the material dumping he promoted had been effective.

But this kind of dumping is beneficial to the wizard.

There are basically no wizards who engage in very unmagical undertakings such as wheat cultivation or breeding.

None of the things being dumped are produced by the magic world itself, so naturally there will be no destruction of magic world-related industries.

“So, your cost of making biscuits basically comes from potion materials and biscuit acquisition?”

These two things were not a burden at all to Tver, who had a potion laboratory, a plantation, and a large amount of Muggle currency.

But for the Weasley twins, whose purchases are not even large-scale, these costs have become a shackle for them to obtain large profits.

Especially since the price of this biscuit cannot be increased, after all, it is essentially just a mischievous toy.

“Yes, actually the biscuits are not bad. The more you buy, the cheaper the price will be.” Facing Tver, George nodded without any concealment.

“It’s just that the potions are different. The output of potion materials is basically fixed, especially some rare materials. The more you buy, the more expensive they become.”

The Weasley twins sighed helplessly.

The development of the magic world in this area has basically stagnated. After all, there are only so many wizards who need to use these materials, and the scale of cultivation will naturally not expand without limit.

“Then if there is a wizard who is willing to provide you with potions and biscuits at a low price, are you willing to cooperate with him?” Tver suddenly asked.

“Low price? How low can it be?” George asked immediately.

Fred frowned and thought.

“Although our purchase price is not the lowest, if it is lower, it will basically be the cost price. Would such a stupid wizard do such a loss-making business?”

“…” Tver took a deep breath.

“I… I have a friend. She runs a plantation and a potions laboratory, and she also has access to cheap Muggle supplies purchased by Gringotts.”

“We can even provide you with a store located in…” Tver thought for a moment, feeling that Knockturn Alley might not be suitable for a joke shop, “a store in Diagon Alley.”

George and Fred glanced at the professor with strange expressions.

“Is this friend you are talking about…”

“No!” Tver realized that he had overreacted, “Ahem, it’s actually Ms. Primpernell.”

“Ms. Primpernell from the Beauty Pharmacy?” George’s eyes lit up.

“How about, if you work together, you can completely reduce costs, and you can also sell canary biscuits in Diagon Alley. The profits will definitely be much greater than what you did in Hogwarts!” Tver said seductively.

“In this case, you will have sufficient funds to develop more joke products.”

“But why did Ms. Primpernel cooperate with us? I mean, we are just two ordinary students.” Fred asked cautiously,

“Ahem,” Tver adjusted his robe, “It just so happens that I am a shareholder of a beauty pharmacy, a major shareholder.”

“I think your product has great potential, and you also have great potential in this area, so I decided to invest in you.”

“You should have told me earlier!” George and Fred suddenly breathed a sigh of relief.

If they suddenly cooperated with a stranger, they would naturally hesitate, but if it was Professor Welfare, they would not have this worry.

After all, the Iron Armor Curse Badge is such a precious thing that the professor gives it to his students every year as a Christmas gift.

It will not deceive them of this profit at all.

The two were immediately excited and Tver pulled him to sit in the corner——

Don’t forget, Tver came here for lunch, and the business was just a whim…
