[HP] Illusion

Dumbledore is playing a big game of chess, but in his old man's plan, he never expected that the development of the wizarding world 15 years later would become so rapid.

At the very beginning, he did spend a lot of hard work——

For example, the twins introduced products similar to Muggle technology. At the beginning, the goal of the two was to make money, but later Dumbledore set a general direction and policy. In addition to making money, it has a greater meaning—— I want to start from the details of life and infiltrate advanced technological concepts bit by bit, so when everyone reflects it, it is no longer possible to leave these products.

For example, he needs someone to help change some outdated and outdated laws in the wizarding world. Hermione crossed the border from the Department of Magical Creature Management into the judicial department.

Dumbledore has no intention of taking control of the overall situation, and now all members of the Change Committee are voluntary, most of them are from the old part of the Order of the Phoenix, but there are also newcomers, especially from the Muggle Technology Interest Group at Hogwarts member.

Don't look at its name related to Muggles, but the members who can enter this group are some students with outstanding abilities, especially a unique system of this group, that is, after graduation, they can directly enter the studio of the twins for internship Opportunities, this is an invisible temptation for many students who have enjoyed the products independently developed by the twins.

A good product, coupled with the twins' advanced marketing model and good reputation, has spread from a small range of Hogwarts students to parents of students, and even merchants and their customers have started to use it. A sea change has taken place.

And even if Dumbledore no longer made any plans during this period, the needs of the magic world prompted major changes in all industries.

In fact, not all products are successful, but in the wizarding world, whether it is contact information, information acquisition methods, product purchase channels, store business models, etc., all have begun to develop towards the successful model of Muggles. In these industries and fields The twins, who are both leaders, naturally became the well-deserved richest man in the magic world.

Such a huge success is not inconceivable in the eyes of later magic history researchers, but the inevitable result of the general environment and the increasing demand of the magic world, such as the decline of pure-blood nobles, and almost all the conservative older generations have retired The post, the reform style of the new generation of successors, the breaking of the gap between Muggle blood and pure blood, and the huge gap between the falling behind and Muggle technology, according to the statistics of later generations, the gap between the wizarding world and Muggle technology There was a gap of nearly 50 years at the peak, but during the ten years since the contact board appeared, the gap was shortened to less than five years.

Although later generations of magic historians did not find the exact proof that Dumbledore was the leader when studying this change, there are indications that Dumbledore is indeed the highest planner behind it, and most of the members of the Order of the Phoenix are This change has more or less contributed.

And it is undeniable that although there are still many areas for improvement in the magic world more than ten years after the contact board appeared, this period is also the most prosperous and prosperous period in all walks of life in the magic world. Going in a good direction.

☆☆☆

In fact, the twins who have achieved great success have not given up on research and development of prank products. Although these products are not the bulk of their money, they are the key to their good reputation and reputation.

Although they have entered middle age at this time, the innocence in their hearts has not changed.

The increasing money gives them more capital to do what they want to do.

It's like the twins of the Weasley family and the twins of the Harry family are working together to research a technology recently. This technology can simply enter each other's dreams. This idea evolved from Legilimency and memory making .But the more they research, the more they feel that this technology is actually not very feasible, and it involves privacy issues, so it cannot be promoted on a large scale, and they have not yet fully developed more functions.

This topic itself is interesting, so the two pairs of twins are not willing to give up, and they always forget to sleep and eat these days.

It was the Easter holiday, and the two twins didn't go home for several days, so Harry, who hadn't seen his daughter and son on the weekend, finally couldn't help but came to the studio of the twins. Unexpectedly, he saw his own child plus George Frey De fell asleep.

After finally waking them up, they were immediately ignored when they woke up. The four of them were quite excited and murmured some words that Harry didn't understand, such as dream shaping, dream collapse, etc., but these had nothing to do with him , he is in charge of catching the two little ones to go home.

Ollie often acted like a baby with her daddy, and when Harry told them to go back quickly, she immediately made a sad expression: "Don't you want to try our new product, Daddy?"

Harry: "...do you want Daddy to wait for you?"

George took Harry's shoulders: "Don't be like this buddy, let alone them, Fred and I are both passionate about our latest research. Before, I thought dreams involved too much privacy, but today we found that dreams have no scope for exercise." Humans can reach it, but we must know that the brain can control the body and memory, so if we can practice magic spells in dreams, it means that we have also learned such magic spells, and the speed of the brain is infinitely faster than the body , so when we sleep for 10 minutes, we have been practicing for over an hour in our dream.”

In fact, he really did not understand.Harry thought silently.

But he does know: "You are only 15 years old now, oh, there are still two months left, when you become adults, you have to be responsible for yourself for what you want to do, but now, you can only be obedient."

"Daddy, don't you think this is definitely a great research?" Ollie didn't give up, and pulled her younger brother, "Neil, don't you think so?"

Neil's face was in a state of facial paralysis most of the time, but today his eyebrows were a little excited, "Daddy, I think this is very helpful for studying..."

Fred also hooked Harry's shoulder: "Dude, maybe you can really try it yourself."

In fact, George and Fred wanted to invite not only Harry, but also the whole family of the Weasley family, Dumbledore and his old partners, Sirius, Lupine, etc., so that they could also test the tolerance of dreams. However, because they were worried about setting privacy and other issues, they only invited their closest people for this experiment, and did not invite students at school as experimenters.

☆☆☆

I don’t know whether George and Fred’s reputation is too famous recently, or everyone’s expectations for new products are much higher than when they made the contact board at the beginning, so when the twins invited their family back in the name of experimenting with new products, Most of the people came back, except for Charlie, Percy and Ginny who was still playing in the Quidditch playoffs, the Weasley family was all there, as for Lupine, Sirius Dumbledore and others, they all arrived as scheduled , especially Dumbledore and Grindelwald, the two little boys in their family kept blowing pillow wind to them, which also made the two elders very curious about the particularity of dreams.

George and Fred's studio is very large and divided into several parts. The most interesting area is their scale-like realistic landscape. This place can make them feel that they are working outdoors, but there is no safety outside. Fabio, today they put their experiments here, and it can be regarded as a large group of people having picnics and parties outdoors.

It's not easy for them to get together. Even Ron, Hermione and Harry haven't seen each other for a month. They are very happy today. They gather, chat and play in the morning, and after lunch at noon, everyone Got to the point.

George and Weasley gave everyone the dream key, the dream connection instrument, while Ollie and Neal served as assistants to assist the two.

George is doing the final debugging work for the dream key, and Fred is introducing the characteristics of the dream key: "We have actually created a dream. If it goes well, everyone will enter this dream. Let's test it for 10 minutes first. Version, so our dream time is exactly one hour."

But when everyone entered the dreamland, they found that a few people were missing.

"Have you seen my dad and daddy?" Ollie looked left and right, and Neil also helped to look around, but Harry and Snape were nowhere to be seen.

"Where are Ron and Hermione?" George and Weasley didn't find their brother and sister-in-law either.

Dumbledore noticed too: "Remus and Sirius are gone too."

Everyone else was there, George thought for a while and said: "We only used the dream potion for 10 minutes, which means that the dream time is one hour, and we will wake up after an hour. If the dream is not too stable, maybe they None of them succeeded in entering the dreamland we set up.”

☆☆☆

Ron, Hermione, Sirius and Remus were in the same place, they didn't find anyone else, but soon, they found Snape.

Still an Age Reducing Potion version of Snape, about ten years old, probably not at Hogwarts.

The place they were in was a grove full of birdsong and flowers, and he looked like he was waiting for someone.

"This is the dream George and Fred set for us? Where are they?" Ron asked puzzled.

Most importantly, why did they show them such a little Snape, what kind of... bad taste.

"He doesn't seem to see us yet." Hermione thought of the rules in the dream that was speeding up just now, just like they can communicate with each other, and people in the dream can definitely see them.

"Are we... going there?" Even Hermione hesitated.

"That's damn it..." Sirius was interrupted by the appearance of another person before he could finish his sentence.

Lupine said thoughtfully, "That's Harry?"

Harry's age has also returned to around 20 years old, but he looks very thin.The two looked familiar, Harry taught Snape Defense Against the Dark Arts and took him to learn to fly.

The situation in front of him was too weird...it was unbelievable for several people.

Neither Lupine nor Sirius spoke, and Sirius frowned.

Soon the scene changed.

Outside the Hogwarts castle, it was snowing outside, and it looked like it was covered in silver and cold, but they didn't feel particularly cold.

Snape, who had grown up a bit, walked outside the castle alone, as if he was depressed about something, his feet were kicking the snow unhappily, and then he walked towards the castle.

After a while, Hermione said suddenly, "He doesn't seem to see us."

Lupine nodded: "This is more like a memory."

Hermione: "Memory is used as the structure of the dream, but if it's really memory... it's a bit unreasonable." If it's memory here, Harry's age will be the biggest flaw in the time period of this dream.

"Where's Harry?" Sirius clenched his fists, he had a bad feeling.

"Let's follow!" Hermione was the first to follow.

They came to Snape's bedroom, and...

The teenage Snape had spotted Harry following him in the Invisibility Cloak, and he looked even angrier, and Harry was a little overwhelmed.

"Is that Harry? He looks much thinner than now, but... how could Harry know such a small Snape?" Ron finally realized the problem.

It was a strange dream indeed.

The next transition scene is more interesting.

Because it wasn't Harry they saw, it was...

Sirius' eyes widened: "Merlin, is that Professor Prince?"

But what they heard Snape yell to this Prince was: "Harry."

Snape once again debunked the fact that Harry was Prince.

Sirius pinched Lupine's hand: "Does it hurt?"

"This is a dream, of course it doesn't hurt." Lupine rolled his eyes.

"How can you be so calm?" Sirius wanted to yell at Tianchang: Who the hell gave them such a broken dream.

"It's you who has a dark history, and you should be the one who is worried." Of course, Lupine knew Sirius' concerns. Back then, Sirius was reckless in doing things and was taught a lesson by Prince. If Harry really is Prince, Sirius still doesn't know how to deal with all this.

The scene changes again.

This time, everyone gasped.

The skinny Harry fell into Snape's arms, dying, surrounded by scorched marks and shocking bloodstains.

Snape looked at the person in his arms with a face full of pain.

"here it is……"

Lupine provides the answer: "The Potter house, where James and Lily ended up being..."

There was the sound of a baby crying.

Sirius wanted to go over and pick up Harry who was crying out of fright, but the scene changed again.

This time, they came to a scene familiar to everyone.

"That's me and you," said a group of people who were decorating Black's old house, but Molly and Arthur were missing. "That was our fifth grade, the year my dad was bitten by a snake."

Harry was also helping with the arrangement, but seemed absent-minded.

Immediately, Snape appeared, and Sirius also remembered this scene, when Snape said that he would teach Harry Occlumency.

There is a question in everyone's mind, what is the meaning of all this?

A new scene appeared again, Harry came to Black's old house, anxiously asked the elf to take out the Slytherin locket, and then Snape also appeared.

"This is a memory..." Sirius said reluctantly.

"I think it's really possible that this is a memory, together with the ones we saw at the beginning." The memory was a little fragmented, but it made Hermione start to have a general idea.

The next memory was something no one had seen, except Snape and Harry.

Harry had a painful expression and kept saying don't force me, but after the two of them hugged each other, Harry's expression became much better.

The memories that followed were relatively complete, until Snape brought Harry back to the house they still live in now, Harry turned on the light, and the two recognized each other...

Sirius was livid.

Lupine finally couldn't help but said, "Is the current Harry actually the same big Harry just now? That is..."

This situation is too weird.

There was a chill behind him, and Ron turned his head suddenly, only to find that Snape was looking at them, and Harry was standing beside him.

They turned their heads again, and the professor and Harry in front had disappeared, and they walked towards the four of them step by step.

"What's going on here?" Hermione was the first to ask.

Harry closed his eyes, and spoke with some difficulty: "It's what you see. I... came from another world, met Sif, and some things happened in the middle. I tried hard to change the history I know , but in the end everything was in vain, Sev established a soul connection with me and allowed me to stay in this world, but I lost all my memories and grew up like an ordinary child until the fifth grade. My memory is slowly recovering..."

Based on the clip just now, Hermione has already sorted out a line. When Harry put everything together concisely, Hermione finally understood that something was wrong with Harry suddenly ten years ago. , that Harry, who looked like an elder, had all the answers.

Hermione and Ron were stunned for a moment.

Sirius didn't speak, but Lupine asked, "We just saw that Severus called Professor Prince Harry..."

"That...is me." Harry looked at his godfather and Lupine with some guilt. "When I entered Hogwarts, it was because of Voldemort. I also wanted to see my father and mother." At first he was unwilling I had more contact with them, and later because of Slytherin, they also walked on the opposite side.

Lupine suddenly remembered: "So when you punished James for writing papers, you were teaching him new knowledge." Even the four of them wrote a lot of papers in those years.

"Um……"

Harry knew that Sirius would be awkward, but everything couldn't be reversed. If he went back to the year again, maybe he would still make such a choice.

It doesn't feel good to be deceived, but in this situation, it's not the time for them to say anything. Hermione and Ron looked at each other and could only communicate with their eyes.

Ron: So it's really the twins doing this?

Hermione gave him a blank look: Of course the Dream Key wasn't stable enough, and somehow it was connected to Harry's brain.

If what Harry got before was a little different from theirs, but the twins didn't make it clear, and they didn't know what it would be useful for.

In fact, what they prefer now is to return to reality...

At this moment, probably everyone is quite embarrassed.

Perhaps Merlin heard Ron's wish, and suddenly, the surrounding environment began to collapse, and they watched the blue sky shatter into pieces, pressing down on them with lightning speed.

☆☆☆

After waking up, the atmosphere among the six people was a bit strange. The twins all realized that something had happened between the six of them. In fact, it could be seen from the expression on Sirius’ face. Afterwards, the twins felt that the multiplayer dreaming system was still not stable. Although Everyone said that this was a good experience, but the twins said that they had to do more research and talk about it later.

George had a private conversation with Fred and Harry. Harry didn't intend to tell them the matter, but said that they entered his memory. Let the twins work a little more on dream shaping, and the complexity of the brain will be reduced. It is the key to the instability of the dream system.

Three days have passed since that day. Fortunately, everyone has their own lives, and they are back on track after that day.Not to mention Sirius, even Ron and Hermione didn't reply to his message. Harry was a little melancholy, but he knew that he should give the four of them time and space to digest this matter.

In fact, Ron and Hermione shouldn't be too difficult to deal with. Although more than ten years have passed since he "woke up", Ron and Hermione have also married and had children long ago, and the children have all entered Hogwarts. Their friendship grew stronger over time, and with such a foundation, Harry believed that they only needed a buffer period of a few days-even during the period when he changed the most, the two tried their best to make him feel better. Get up, let him reintegrate with everyone, so he doesn't worry too much about Ron and Hermione.

Sure enough, after three days passed, the two sent a message, saying that they wanted to meet again. The two of them still had to be on duty during the Easter holiday, so they could only do it on weekends.

In fact, it was Sirius and Lupine who were really difficult to deal with. It might be better to have Lupine around, but Sirius' own thoughts were the most important.At that time, he was with Snape desperately, and Sirius reluctantly accepted it. They have been together for so many years, although Sirius still doesn't have a good face towards Snape, but as long as the two of them are not face to face

I don't know what Sirius would think. He did almost kill Snape back then, and he was a lesson to him later, but he didn't do anything cruel. Speaking of which, Snape didn't know what he thought when he knew about these things. of.

"It's good that you're alive."

Harry turned slowly to Snape, who was standing behind him.

After 15 years of loss, how did the man come here?

A dream, but more like tearing apart the man's most painful memory.

"I don't care about that, you know." Snape slowly moved closer to Harry, wrapping him in his arms.

Maybe it's because he has experienced too much, so much that as long as this person stays by his side, he can ignore those painful memories that almost make him despair.

The two exchanged a wet kiss until the oxygen ran out, and Harry felt the heat of his body as he pressed his back against the cold wall behind him.

"They'll all want to, because they've accepted you as you are now." Snape kissed Harry's forehead lightly.

☆☆☆

Ron and Harry had an appointment at Hogsmeade over the weekend, and Harry arrived much earlier.

In the past few days, he has gradually become less irritable, but when he really wants to meet Ron and Hermione, his mood is still up and down.

Ron and Hermione arrived on time with calm expressions, which made Harry a little overwhelmed.

The three people who usually have countless topics when they get together, fell into a strange silence today.

The closer people are, the more embarrassing they are sometimes.

Harry took a deep breath and made up his mind: "Is there anything you want to ask?"

Ron and Hermione looked at each other, and Hermione acted as a representative: "We have a lot of questions, but I want you to listen to us first."

Harry was startled, and then put on a look of listening attentively.

"We don't know what you've been through, but no matter what, you're still you. Even when you were the strangest, we didn't lose our initial feelings for you. Of course, your performance at that time was really..." Hermione put on a nasal voice as she spoke, "Actually, what we want to say is that I know that the friendship between the three of us will last forever and never change."

It was a little more perfect than Harry had expected.

At some point, Harry's fists were clenched, his lips were trembling, and his expression was indescribably excited.My heart relaxed.

His husband told him that in fact they had accepted him, but they just needed time to digest.

No matter which world it is, Hermione and Ron are the most indispensable pillars behind him. Speaking of which, in both worlds, he has different degrees of guilt towards these two people.

"Of course." Harry stammered rarely.

"I'm sorry, I kept it from you all these years."

"Everyone has their own secrets." Ron patted Harry on the shoulder. "I just want to know, in your world, are Hermione and I still together?"

Harry: "..."

"Not together?" Ron looked at Harry anxiously, "So Hermione dumped me?"

Hermione glared at Ron angrily, "What's your problem?"

Ron said as a matter of course: "You are so nice, I will definitely chase you, so the reason why we are not together in another world must be that you dumped me."

Hermione's face turned red all of a sudden, probably not the kind that turned from embarrassment into anger.

Harry secretly gave Ron a thumbs up. Ron is really getting smarter.

"Actually, you..."

Ron and Hermione watched him breathlessly.

Harry smiled slightly: "Actually, you are a match made in heaven, haven't you been like this since you were very young?"

What kind of pot should match what kind of cover, as long as it is stable and stable, not everyone wants to be like him and his husband, who are separated from life to death.

Fortunately, we are still together in the end.

"Hey, how could you scare us like this?" Ron patted his chest, and said to Hermione, "Look, I just said that we will definitely be together."

Hermione looked at Harry with a serious expression: "Beforehand, I haven't thought about our being in another world."

☆☆☆

Sirius ignored him for days, and of course Harry couldn't say anything.Comparing his heart to his heart, if he were Sirius, maybe he didn't know how to face this matter.

It seems that he can only figure it out by himself.

But what Harry didn't expect was that Snape took the initiative to find Sirius.

Not to mention that Harry didn't expect it, even Sirius didn't think that Snape would take the initiative to find him, and he still sat quietly in the shop drinking tea and chatting like this.

In the past, if Snape would take the initiative to ask him out, even Sirius would think that someone was playing a prank, but this time it was the Patronus who came in person, so Sirius felt very complicated.

"Are you trying to taunt me? Or come to see me laughing?" Sirius spoke first this time.

They have been like this since they met in Hogwarts, pinching them when they catch them. Even if they have a bridge like Harry now, they will at most ignore them when they meet, which is definitely not the same as being friendly.Snape was used to it long ago, but he never thought that Sirius would be willing to attend the appointment.

This may mean the first step in... reconciliation.I just don't know if the other party thinks so.

Although Snape didn't like Sirius, he still understood his husband's attitude. It would be a lie to say that Harry wasn't depressed.

Sirius died because of him in his previous life. In this life, even if he doesn’t think this is a real world, subconsciously he still fears not wanting to touch his closest relatives. If it wasn’t for Lily growing up with him, it would always be a coincidence Maybe Harry wouldn't touch Lily either.Harry was also sick at that time, and any choice he made had something to do with his mood, so that he was the only person closest to him.Later, the relationship between Harry and him became deeper and deeper, but Sirius went to his death in the name of fighting against black magic. Harry made a move, but he didn't really do it. He could understand all this, Harry Let him stand out, although he didn't have a good impression of this person, but he didn't pay too much attention to him, but I am afraid that he will not like him all his life.

But Harry still cared about Sirius in his heart, and he didn't want his husband to be depressed all the time.

Snape's expression was very indifferent, looking as if the matter had nothing to do with him, "Are you planning to keep doing this in the future?"

"What kind?" Sirius asked in a deep voice.

"Or are you going to let Harry seek peace first?" Snape asked coldly.

The Potions Professor's expression seemed to be saying "what are you capable of", which made Sirius almost lose his temper, "Are you here to solve the problem, or do you want to fight?" up.

"It seems that you really want to solve the problem. If you feel ashamed of being punished by Harry for the things you did before, then I forgive you, and you don't have to be depressed about those things anymore."

Sirius:"……"

"In fact, Harry has always felt ashamed of his godfather, so during the final duel, he even arranged for someone to watch you—"

Sirius, who had never heard of such an inside story, was stunned. Although he later heard that Voldemort's death was related to Harry, it was Dumbledore who came forward at the time, and the insider was vague about the final duel, so he Even Harry never said he had anything to do with it, and the truth was played cold afterwards.

"What did you say?"

"What I said is the truth. He is worried that you will leave him again."

Sirius:"……"

"You don't think it looks like him, either?" Snape's voice was soft. "You know we are soul mates, then you should know, I can know what he thinks."

Sirius was actually very displeased with the scene of being passively beaten today, but these things were beyond his cognition, so the psychological construction he had done these days completely collapsed.

"Harry asked you to come today?"

"Obviously not, he doesn't know," Snape said with a glance at Sirius. "If I remind him, he will know immediately."

"Actually, what I want to say is that for a while he was sick, very sick, not physically but mentally, and his thinking was largely influenced by these emotions, and he thought that would be best for you, He is worried about everyone, and if I don't say this, probably no one will know about it in the future." Snape looked serious.

How much pain Harry had, he didn't want to share it with others, only he knew, he shared it, and that was fine.

"He died once, and the history before that cannot be changed, so no matter what he tried, the history he knew still happened."

To be honest, Sirius was completely dumbfounded at this time.

Snape dropped another cannonball: "Having heard all this, do you think you still have a position to accuse him of what he has done?"

Sirius vaguely felt that Snape's logic was wrong, but he couldn't say anything to refute it.

He loves his godson, although Harry may not do all the right things, but Sirius still feels very uncomfortable when his godson has experienced things he can't imagine.

"I see." In the end, he left only this sentence and left.

Snape sat where he was, and breathed a sigh of relief.

When a person was partial to the point of his heart, no matter what the person did, even if he didn't agree with it - of course he couldn't object at all when he was young - Snape would only want to share with him.

Especially after knowing the truth of everything.

Since Harry got sick, he used to take on everything by himself. At that time, Snape didn't know what was wrong with him, but consciously or unconsciously, he spent a lot of effort to make him gradually depend on him.The seeds of emotion have already been planted, but they have been covered in dust before they blossom and bear fruit.Now Harry is finally on the mend, and everything is going in the ideal direction.

In fact, no matter from whose standpoint, what Snape said to Sirius just now was too much, because Harry had indeed concealed these situations, whether it was because of man-made or environmental factors, the concealment was In fact, what Snape did was use Sirius' love for Harry to force him to accept such a thing.

But from another point of view, the facts can no longer be changed, so we should always try to start again—obviously, Harry and Sirius had already started again before the matter was exposed. They got along so well all these years, could it be fake?

In a way, Snape has confidence in Sirius' love for Harry. Apart from the responsibility of the godfather, there are also the guilt of those ten years. The measures he had taken had punished him and left his ego wounded and torn apart.

It was wrong for him to do so, but it was also the best way in such a deadlock.

They just need a bridge to connect them, and they can easily get together again. Even if they have a bridge, the two of them are definitely not in a relationship where they are still hesitant to stand on the other side.

Perhaps these are things that Snape in another world has never felt.

If Harry hadn't appeared, then he would have ended up like another Snape, living in regret, guilt and atonement until he died, instead of having a happy family and the best husband as he is now, There is a pair of troublesome children.

All difficulties are over, and life is now the fruit with the sweetest taste.

In this way, it couldn't be better.

Of course Harry also knew that his husband had found Sirius - as long as he wanted to know, there was no way Snape could hide it.

Compared with the motivation, Harry was actually more surprised that his husband went to find someone who would never take the initiative to find someone.

This caused Harry to lose his speech function for a moment.

Snape looked at his husband expressionlessly, but that didn't stop Harry from noticing the red tips of his ears.

"I……"

Before he could speak, he heard the sound of the contact board.

Snape glanced at the screen, "Look at the message, your godfather can't wait."

Harry: "..."

Harry leaned forward lightly, planted a kiss on Snape's lips, and then opened the contact plate.

The message on the contact board wasn't long: Harry, let's make an appointment to meet.Sirius.

In fact, the contact board has already had a real-time stereoscopic vision function. As long as some magic power is injected, you can talk to each other face to face. It is said that this is similar to the projection technology of Muggles. George and Fred are trying to realize it. It is said that if they succeed , this is not only keeping pace with Muggles, but even surpassing each other by hundreds of years.

The contact board is handy, and Sirius still opts for face-to-face
