This is what Ravenclaw looks like.

"Is this the daydream spell?"

Andrew looked at the thing the twins took out in confusion. Rather than saying it was a spell, it was more like an alchemy-related product.

"Yes, Taylor, as long as you cast a spell on this thing, you can get an absolutely realistic, 30-minute daydream."

Fred answered very confidently.

"Then how do you define a beautiful dream?"

Andrew handed the small box back - although there would be no pitfalls in theory, he never dared to underestimate the courage of Gryffindor.

"It can be completely customized. You can cast spells to create anything in your dream, just like an all-powerful wizard."

"Anything?"

Andrew looked at it, "So, things in dreams can really be completely self-defined, just like Percy said?"

"Not so all-powerful. We used some potion ingredients and solidified some scenes when making it, but the degree of freedom is very high."

'The degree of freedom is very high... I always feel that the use will be in strange places,' Andrew shook his head slightly and asked, "Can it be interrupted autonomously?"

"Yes, and it will stop once the powder inside is used up, but because of the encapsulated spell, it will not work anymore."

George quickly added, with a guilty tone.

Originally, the two of them were very sure that Taylor could pay the reward, and they were even more sure when they saw Taylor presiding over the sorting ceremony not long ago.

But the question now is whether the other party will value their things-although they are confident in their products, but in front of Taylor, it is obvious that the gold content of this trick is a little insufficient.

"Can I disassemble it?"

Andrew roughly guessed the principle and asked.

"Of course, no problem," Fried handed the item over again with extraordinary confidence.

Andrew carefully tapped the sealed small package with his wand - it instantly broke into pieces, but under the suppression of Transfiguration, none of the spells that should have been triggered took effect.

'Potion powder, um, this, this, and, yes, this too, are the three spells linked to the new spell? '

'This is a weakened version, um, interesting, I didn't even make such an assumption on the spell - the Confusion Spell can be used like this, maybe the professor is right, I did put less effort into the spell...'

'This is, a cover magic to keep a normal smile on your face? Things used for sleeping in class... um, useless...'

'This, I feel it should be a spell to control dreams, it is to enhance imagination, I have never heard of this spell...'

He used Transfiguration to find out the ingredients of the medicinal powders - very interesting, there is a big problem with the ratio, although the effect is there, it will easily make people drool or simply lose their energy...

'I have the idea, but I am not very skilled...'

"The spell is sold together, right? What's the price?"

He nodded - it completely met the requirements.

"Yes, it's all together," Fred suddenly became energetic, he and George looked at each other, and carefully quoted, "How about eight hundred Galleons?"

"Eight hundred..."

Andrew thought for a while, "One thousand Galleons, don't try this in the future, the formula is not quite right, and although I will sign your name if there is a follow-up development, you are prohibited from having any relationship with me when selling the product."

"One thousand???"

The two of them didn't pay any attention to what Andrew said afterwards, they were both focused on the huge reward.

"Yes, one thousand Galleons, but you must abide by the principles. If you are okay, go to my laboratory and sign the contract now."

"Now?"

George opened his mouth in surprise.

"Tomorrow is fine, you can think about it again, or later, but it is best within three days," Andrew nodded, "I really need to think about it."

"No, we don't need it, it's fine now," Fred nodded quickly, and George beside him also reacted and began to nod quickly.

Probably because they were afraid that Andrew would go back on his word, the two of them began to quickly take things out of the schoolbags behind them.

A piece of parchment with a handwritten prescription, more than a dozen pages of spell instructions and an old book.

"Those two spells are from the library, with page numbers and actual instructions. This one is obtained by the two of us on an adventure. There are some more interesting spells, and I sell them to you together. The third spell is in it."

Uh...

They are also careless-they dare to learn spells from any magic book.

Andrew quickly examined it and it did meet the requirements, and judging from the texture of the magic book, it was indeed not forged.

"Then let's sign the contract now?"

He invited them, and then took them to his laboratory. After a moment's hesitation, he didn't bring anyone in. He cast a spell to lock all the drawers and cabinets, and dragged out a new set of tables and chairs separately, and then began to draft the contract at the door.

It's not that he discriminates against the two of them, but they have too many precedents.

Obviously, they also know about this and have no opinions.

Half an hour later, the contract was drafted, and Andrew dragged the two to the dean's office-a third party witness is required to sign the contract.

The reason why it was the dean's office was also very simple. If the dean really checked in advance, he would have an excuse.

——

"A magic to control dreams, or a combination of spells?"

Professor Flitwick suddenly became energetic, "The price is quite suitable, Taylor, it's a good breakthrough."

No mistake, one post, one content, one 6, one 9, one book, one bar, take a look!

He turned his head and looked at the twins, "But do you really not need to ask the parents? After all, it's a big deal."

"Percy recommended it, and Mom will definitely agree."

The two answered very firmly - let alone one thousand galleons, six hundred will do, as long as the parents are not notified.

Six hundred is enough for the start-up capital, one thousand is simply taking off!

"Well, Percy's words are indeed possible," Professor Flitwick nodded, "Then, I will prove it for you."

Soon, the contract was signed, and Professor Flitwick smiled and nodded to Andrew, "You have passed the summer homework, Andrew, study hard, don't waste such a good idea."

"I will, professor."

Andrew nodded seriously and said goodbye to the professor, then took the twins out of the dean's office and walked towards his laboratory. He didn't bring galleons just now, and now it's just right to withdraw money.

"Cash or Gringotts draft?"

He turned to ask the twins, but found that they looked unhappy.

Without thinking, Andrew pulled out his wand and cast the Shield Charm almost immediately, then, "Mr. Andrew?"

…

"Good evening, Mr. Filch."

He turned to greet.

"Did you catch the wandering Weasley brothers?"

Mr. Filch's face was shining, and he looked very happy.

"No, I have something to discuss with them, Mr. Filch."

Andrew shook his head.

"That's a pity... I'm patrolling somewhere else."

Filch shook his head and walked towards the next corridor with a lantern.

About ten minutes later, he took the twins, took the cash, put it in the pockets and handed it to the two, and sent them back to the Gryffindor common room before turning and leaving.

——

"It's just two treatments, George."

"Not only that, there's something else. We overlooked a very important thing during the holiday."

Fred suddenly remembered something and shook his head.

"You mean, that?"

"Yes, that, we saw it when we got off the train... it's right over there, we can go there during Hogsmeade week, it's better than dealing with Dumbledore's restrictions."
