"You two are geniuses!"

While Harry was thinking, some of the nervous twins didn't choose to wait stupidly, they knew very well that they couldn't be trusted just by talking about it, Harry was busy, very busy, even if the twins weren't from Hufflepuff House, they knew that Harry's terrible class schedule, the students approaching the N.E.W.T exams didn't squeeze themselves so hard, and they needed Harry's help a lot.

So, the twins showed Harry what they had done in the last few months.

Although the experimental materials in their hands only have the feathers of the ball birds, as long as there are 'rice', their 'clever women' can still make unexpected results in the limited space to play.

The biggest use of the ball bird feather is as the main material of the emergency escape device, this kind of prop that can make people unconditionally teleport after activation has no price in the black market, and unlike phantom shifting, this kind of emergency escape device can ignore the restrictions of the anti-phantom shifting spell on the illusion shift, and safely send people tens or even hundreds of meters away.

As a magical creature that has been born with the ability to teleport, the talent and ability of the ball bird in space shuttle has thrown wizards off hundreds of streets, and even the space restrictions that house-elves can ignore are as if they do not exist in their eyes, even the props made of their feathers have some qualities.

However, this kind of emergency escape device is not just a ball to escape bird feathers can be made, for a long time, only a few alchemists have mastered this technology, even if someone gets the design drawings, if they don't have enough ability, then there is no way to start, the third grade can only start the elective alchemy class, its complexity is no less than the most difficult metamorphosis in magic, which requires both brain and hands-on ability and countless hours to slowly grind the subject, the threshold is outrageously high.

The twins, who had just entered the third grade, naturally couldn't have mastered alchemy in a few months, although they had only mastered some basic introductory skills, but they had learned very solidly, coupled with their unbridled imagination and super hands-on ability, they had developed a somewhat stupid way of teleporting.

Whether it is a portkey or a phantom shifter, the spatial movement of the wizarding world is quite magical, wizards do not need to carry out complex coordinate calculations, nor do they need to make complicated preparations, they just need to 'imagine', imagine where they should go, and then with a slight turn of their body, the person will disappear in place with a swish, and instantly appear at the target location.

For most wizards, the destination of teleportation is best to be the place they have been, because this will help them to make up the correct direction of the landing, but for some wizards who are skilled in phantom shifting, he does not need to go to that place, or even look at that place, they can come to the target point inexplicably according to a name, and even some wizards don't even need a name, he just needs to know what kind of conditions the place he is going to, then they can also come to the target point.

When apparition, wizards are able to perceive the image of the location of the landing point 'halfway through', and they can even 'see' other places along the way, and if the target point is not where they want to go, they can choose a new coordinate to appear.

This kind of magical space teleportation is too idealistic, not to mention that science can't explain it, and even the wizard himself can't explain what the principle is. (The premise here is from the seventh book of Deathholy, where the trio Apparition prepares to go to 12 Grimmauld Place, and the description of this magic when learning Apparition in Year 6.)

The twins' relatively clumsy props can't compare to this outrageous magical teleportation, and they create a prop that can lock onto any visible spot in the field of vision, and then deliver the item accurately.

It was a crude prop about the size of a baseball, and Fred was standing in a corner of the room during the demonstration, and after pressing the button on it, he gently tossed the ball, which had not yet begun to free fall and disappeared in the blink of an eye, and by the time it was found, it had already reached the other end of the room.

"It's a test that we spent all our money on, and luckily there were no mistakes in this test, otherwise we wouldn't have been able to make a second one."

Fred gently placed the ball on the table, "Due to the limitations of materials, and because of our current experience, we can't do it yet, so we can't get him to reach the destination with anything, but we have taken the first step, we have completed the research from zero to one, as long as we have the resources and time, we are confident that we will continue to improve it." ”

"We can't teach those who have forgotten how to fight in an instant, but at least we can keep them away."

George added, with the same pride on his face as Fred.

"That's not all we planned, Fred and I designed the Wizard Hazard Guard Suit with a spell cap and iron robe, these things were inspired by the news brought by Professor Grindelwald, the alchemy item with a mechanical mind gave us inspiration, and the most inspiring thing was its trigger mechanism."

"We begged Professor Grindelwald to lend us something to study, and while we couldn't make it exactly the same, once we figured out how it was designed, Fred and I should be able to figure it out with a little time."

"Alchemy is a fascinating subject, and by combining different scripts with each other, they can compile anything we want."

"We think we have a talent for this, even if the professor only teaches us the most basic knowledge in class, we can already combine and arrange the magic texts to make the effect we want."

"Yes, talent is needed." Harry looked at the ball on the table in a daze.

"However, I suggest you make a separate list of this thing, you can have a curse cap and iron armor in your hazard protection suit, this thing.... I don't recommend you to go to market in the future. ”

Teleportation was not particularly unusual for the Weasley twins, who had always lived in the wizarding world, and they were unaware of the dangers of this invention.

"Why do you say that, Captain?"

Fred said a little strangely, "Isn't this just for those wizards who are about to become squibs?" ”

"If you want to use this device to teleport people away, I think it will be very troublesome, right, you need to ensure his stability and safety, this requires a lot of tests, and it may not be possible to complete it for several years, although I don't know much about the principle of spatial teleportation, if I guess correctly, the larger the volume of such alchemy items, the higher the difficulty, and the more expensive the cost."

"Yes, indeed...."

The twins scratched their heads a little embarrassed, according to their estimates, if they want to teleport the wizard away, relying on their design ideas, then this device will definitely not be able to make such a portable type, the few defects of alchemy items are that the alchemy array does not accept 'compression', if the magic cast becomes smaller, the magic inscription inside will be more or less affected, or even invalid.

"But what if you only need to send away small items?"

Harry picked up the ball from the table, "We don't need to put too much of a burden on it, we just need to add a delayed fuse and stuff a two-ounce high-powered burst potion inside." ”

"The spell has a trajectory, and the speed of the spell flight is not fast, at least it can give the trained person time to dodge after the spell is fired."

"But this thing..... Don't forget, this is Hogwarts, Hogwarts Castle where apparitions are forbidden. ”

Harry shook his head slightly, "If you succeed in your research and make it really capable of teleporting anywhere in your field of vision, then congratulations on becoming the world's most notorious terrorist arms dealer." ”

"Welcome to Azkaban."

Harry reached out and grabbed the twins' arms and shook them hard.

The twins, who had realized what was wrong with their invention, turned pale, and once this thing was promoted to the shelves, then there would definitely be smart guys who would think of this, after all, people can teleport, so what can they do if they send some goods.

"Should we ..... it?"

Fred swallowed silently.

"Probably forgot we studied this thing....."

George's face was a little gray, but even if they were unwilling, they couldn't release this kind of thing that would cause a big mess.

"Is it complicated?"

Harry asked, flapping the ball in his hand.

"It's not too complicated, after all, we've only been learning alchemy for a short time, but we accidentally invented a new combination of magic texts to locate and channel magic power."

Fred shook his head, knowing this, and because of this simplicity, he must not let this technology leak out.

"The feathers of the Ball Bird have certain characteristics of their unique spatial movement, or in other words, the long-term spatial movement of the Ball Bird instead of the walking Ball Bird makes their feathers more adapted to the space, and the magic remaining on it is a key, the key that can break the spatial distance."

"Our magic combination channeled the magic in it, and to be honest, we didn't understand what spatial movement was, and the only reason we were able to do this was because we used a specially treated ball bird feather."

"All the power comes from it, and if it weren't for that, how could we, who haven't even learned how to apparition, make such a prop."

The smiling twins took the ball from Harry's hand and smashed it to the ground without hesitation.

"We don't make this money anymore."

"Didn't hear me, Harry, we're sure you won't tell anyone about it."
