This Hogwarts isn't normal.

"Here, this is our gift.

Fred and George gave Astoria their latest prank props.

A bottle of red and blue pills, and a pair of ordinary sunglasses.

"What is this?"

Fred grinned, "The red pill is a strong laxative, and the blue pill is a special antidiarrheal medicine."

If the person being pranked takes two red pills...

The simple Astoria seemed to understand something.

As for the sunglasses that are nothing special, they are amazing.

If you encounter some bad guys with bad intentions, just put it on and touch the frame, and the lens facing outward will emit a dazzling strong light.

"Is it really that amazing? "Astoria put on her sunglasses, and the world in front of her suddenly darkened.

She looked a little eager to do something, but she didn't try it in the end.

Hermione was relieved.

She had ideas, but she could control them.

People with good natures can't be that bad.

Vincent actually prepared gifts for his friends, which were some finalized alchemical products.

The functions were not powerful, but they were quite convenient to use.

When Cedric and Qiu came in, he just took out a thick manual.

The twins didn't tease them, but focused on the flat rectangle in Vincent's hand.

George picked up another rectangle, "Is this for knocking people?"

"Of course not. Vincent opened the manual with one hand,

"It is a short-distance communication device I made based on the principle of a two-way mirror and combined with a walkie-talkie."

He pressed his thumb to the middle of the rectangle.

The rectangle in George's hand vibrated.

"Press the middle."

After doing so, a magical scene appeared.

A faint light lit up on the front of Vincent's cuboid, revealing a big chin.

"Merlin's big pants!" George quickly looked down at the cuboid in his hand.

Vincent's cuboid face appeared on it.

"Are they the same as two-way mirrors? Are they connected by magic?"

"Not exactly." Vincent picked up the third and last cuboid.

After he pressed it, the other two immediately vibrated, and the picture was divided into left and right sides.

"You know about walkie-talkies? As long as you adjust different frequencies, the paired 'magic communicator' can display the picture."

Except for Hermione, everyone shook their heads to express their incomprehension.

The book-sized two-way mirror uses magic to connect the two mirrors together, so that as long as you call the name of the owner of the other mirror, it will reflect the picture it "sees".

The walkie-talkie is a terminal device for cluster communication, which can receive designated signals after pairing.

The magic communicator is a device that combines the two to achieve instant communication.

Cedric opened his mouth in surprise after understanding it.

"So, this thing can communicate like the fire in the closet?"

Vincent nodded, "But that's the final form. I'm still worried about how to transmit the sound without being interfered with by magic."

Hermione made a suggestion, "The closet can transmit items, how about referring to this way of transmitting sound?"

"It's too cumbersome, and it will be regulated by the Ministry of Magic."

After building a global communication network like the Floo Network, the magic governments of various countries will 100% strictly regulate it for the sake of security.

If the privacy of customers cannot be guaranteed, the market cannot be further expanded.

"What if an agreement is signed?"

"I don't think they care about the privacy of wizards."

Not to mention the long-term, even if Fudge agrees on the surface, he will secretly set up a department dedicated to monitoring.

Solve the danger before it happens, especially the hidden danger that shakes the position of minister.

Hermione's eyes dimmed, "If you can come up with a way to bypass the supervision, they will also force you to add a backdoor."

"There is always a way to resolve the conflict." Vincent was very optimistic.

In the face of powerful forces, the threats from the magic governments of various countries are just a joke.

The conversation between the two of them made everyone more and more confused.

Daphne and Cedric were fine, and they barely understood that this was an irreconcilable contradiction between human rights and maintaining the security of the magic world.

Qiu, like the twins, didn't quite understand why the magic government was monitoring.

Astoria didn't understand it at all, but the serious thinking proved that she had tried very hard.

She couldn't figure it out no matter how hard she thought, so she simply picked up a magic communicator and played with it.

It was very light and convenient, and it didn't stick out when put flat in the pocket.

The compartment door was opened from the outside.

Rolf came in and found that the atmosphere was not right, "Are you talking about something serious?"

"Yes." Vincent raised the magic communicator in his hand,

"New product, do you want to experience it?"

The picture was a little blurry and the sound could not be transmitted.

In terms of function, it is no match for expensive alchemical items such as two-way mirrors.

But in terms of portability and cost, the magic communicator is much better.

If the sound transmission is added, it will undoubtedly be a great invention that changes the magic world.

It's a pity that it can't be realized in a short time, and even if it is realized, it will be difficult for wizards to accept the life of being monitored.

Rolf put down the magic communicator with regret on his face, "During the summer vacation, my grandfather said that Muggles have shrunk the phone to the size of a brick.

This thing is smaller than it, and it can also display pictures."

He knew that such advanced alchemical items could only be hidden due to the obstruction of the magic governments of various countries.

Then as time went by, the Muggles finally invented similar communication equipment.

With sound and images, the International Statute of Wizarding Secrecy would become increasingly difficult to comply with.

But at a price of less than one-tenth, the picture became clearer and clearer.

And it supports multiple people, and is more portable and resistant to falling than a two-way mirror.

"It will definitely sell well!"

Everyone agreed with his opinion.

Vincent balanced the cost and user experience very well.

The automatic writing feather pen is only 10 Knuts, and the small bracelets in various tool forms are only 1 Galleon.

Rove was amazed, "Convenient functionality, extreme cost-effectiveness, the old antiques of the International Alchemy Association will be anxious."

The guys' evaluations were all very high, proving that low-end mass production of alchemical items is feasible.

Vincent was slightly excited for a few seconds, and then suddenly became dejected.

The assembly line progress of the alchemy factory is about zero, and while researching and developing, quality control must be taken into account as much as possible.

There are a lot of courses in the new semester, so I have to become a master of time management.

After saying this sad news, Fred and George were the first to quit.

"What's the point of taking the old liar's class?"

"You grew up in a Muggle family, do you still need to take Muggle Studies classes?"

"Knowledge is power!" Only Hermione could understand his choice.

She thought that Vincent, like herself, had a strong interest in learning.

However, the reality was just the opposite.

If Vincent hadn't been expecting the benefits that Dumbledore said, he would have canceled a few elective courses.
