There is little magic involved in this protective suit, and at its core is the creatures in the middle layer, which will protect the person wearing the suit after being hit by the Avada Death Charm.

According to the characteristics of different spells, research specific protective products.

Ai Wen put forward this idea, they don't necessarily have to think from the perspective of magic, and the protective products they make don't necessarily have to involve magic, as long as they have an effect, there will definitely be a lot of people willing to buy it.

Many Muggle items and ideas are also highly protective against the dark arts.

Of course, these things are more restrictive than magic items, and most of them seem to be more frivolous. For example, a simple spell would render Muggles' electrical and mechanical devices useless, and not everyone wants to wear a product like the Killing Curse Suit every day.

The real direction of development is still in alchemy, and wizards are more accustomed to accepting it.

Evan told Fred and George about what he had seen at the International Alchemy Congress, suggesting that the two of them contact the teams to work together on the crafting of alchemy equipment.

"The magic weapon that the American team has developed can replace the wand, although it is not yet mature......"

As he spoke, he stopped abruptly, turned to look at the open door, and Hermione hurried in.

She looked worried, as if something had happened.

"Hermione?"

"What's the matter, are those house-elves rejecting you?" Fred asked with a smile.

"It's to be expected, don't talk to the elves about vomiting anymore......" George said.

"It's Harry and Ron, the two of them are gone. Hermione said anxiously.

The atmosphere froze, and Aven, Fred, and George all stared at her.

Harry and Ron are gone, where did they go?

You know, Harry's safety is very important at the moment, if Voldemort and the Death Eaters take him away......

"There's no way they're going out, Hagrid is on guard outside, and if anything happens, he'll find out. Fred immediately said, "He's not going to let Harry and Ron run around." ”

"So, they must still be in the shop, maybe there were too many people, and you accidentally missed it......" George muttered, "Don't worry, Hermione, we should go out and have a look, I dare say, what bad things those two boys are hiding behind the counter in the corner." ”

"I've looked carefully, and the two of them are definitely not there. Hermione said with certainty.

"If that's the case, then it's a serious problem. ”

"Does Mom know about this?" Fred asked solemnly.

"I didn't know yet, she and Ginny were at the counter looking at the drumming dwarfs, and Mr. Weasley was pondering the Muggle playing cards, and neither of them noticed that Harry and Ron were gone, and I didn't dare tell them......"

Fred and George's shop is not Hogwarts, and there are many ways to get a person away from it.

But no matter what the method, it needs to have the cooperation of Harry and Ron, otherwise the fight will definitely attract attention.

Even if the Imperius Curse is used suddenly, this is not very likely.

Harry and Ron must have left on their own initiative, Harry was able to get around Hagrid with his cloak of invisibility......

The only person who could make him suddenly interested and take the initiative to chase him out without consulting them was probably Malfoy.

"Don't worry, Harry used his Cloak of Invisibility to sneak out with Ron, I know where the two of them are. Evan said to Fred and George, "Hermione and I are going to get them back, you don't let Mrs. Weasley find out about it, and if nothing else, we'll be back in ten minutes." ”

After he finished speaking, he took Hermione directly into the apparition.

The next second, they appeared in Tumbledown Alley, a small street closely associated with black magic that was deserted.

Even the shops on both sides are quiet, and there seem to be no customers in each store. The street was ostensibly still under the control of the Ministry of Magic, and no one would be willing to buy during this dangerous and suspicious time, or be seen buying dark magic artifacts, that would reveal their identity.

"Tumbledown Alley!" Hermione looked around nervously, "Harry and Ron will be here?"

"He must have seen Malfoy come here before he came along. Evan said, recognizing his direction, "Animagus shapeshift, Hermione, don't let anyone else see us." ”

Two cats, one black and one white, appear on the streets of Tumbledown Alley, moving forward in an unobtrusive manner.

They made their way to the Borgin Burke Dark Magic Shop, which sells all sorts of sinister and ominous things.

It's the biggest dark magic shop in Tumbledown Alley, if Malfoy wants that......

Sure enough, through the dirty window, Evan saw Malfoy standing behind the big black cupboard, talking in high spirits.

The owner, Mr. Bogin, a man with shiny hair and a gauntlet figure, stood in front of Malfoy at this moment.

The expression on his face was strange, mixed with resentment and fear.

Evan had met the future Mr. Borgin, who was very old at the time, with a very crooked body and wrinkled face.

The decline of the Dark Arts has caused the business of the Borgin Burke Dark Arts Shop to plummet, but he is still doing business with Voldemort's daughter Delphi, who was finally scared to death by fifteen-year-old Riddle, and if this is the end of the largest supplier of dark magic products, it will be miserable enough.

"Meow!" Hermione let out a low cry.

Evan knew that he must have wanted to ask where Harry and Ron were?

The two of them were wearing cloaks of invisibility, perhaps hiding around here, or following Malfoy into the store.

Evan didn't think that was likely, the store was full of boxes full of skeletons and old bottles, and the space was too cramped to be discovered.

He and Hermione didn't dare get too close, it was so strange for two cats to walk in!

"Meow!" Hermione called again, raising her front paws.

Following the direction he was pointing, Evan saw a telescopic ear extending from the window on the side of the shop, continuing intermittently, eventually disappearing behind the pile of old bottles, where Harry and Ron must be hiding.

"Meow!" Evan replied, motioning for Hermione to come over.

Before they could do anything, Malfoy and Mr. Borgin stepped out of the shop.

Malfoy looked triumphant, and Mr. Borgin had a stiff, fake smile on his face.

Evan and Hermione tried to act like cats, Malfoy didn't suspect it, and he was going to kick Evan as well.

Evan dodged with a leap and jumped onto the box next to him, and Malfoy cursed.

Hermione ran into the corner where Harry and Ron were, turned and vanished......
