Hogwarts passer-by professor

Chapter 410 Taking parents into Diagon Alley
"I know a lot of magic. For example, the whirlwind I used for cleaning just now-this magic can clean the dust in the room."

"Also, I will also use the magic to clean up stains!"

"Is it so magical? Then we won't have to clean our house anymore!"

"Of course, not only do we not have to clean, we don't even have to cook in our house. Let me tell you, I have a magic that can make food continuously replicate and increase... and I can also cook automatically..." Aisen talked eloquently. , while speaking, he showed some tricks in front of his mother.

"That's really convenient! By the way, wizards don't want people to know their existence?" Ivy was particularly curious about this.

"Uh, yes, around 1692, the wizarding world came up with a rule called the "International Federation of Wizards Secrecy Law." Eisen said and shrugged.

"Is the confidentiality law worried about ordinary people being harmed by magic?" Ivey asked.

"Uh, no! The reason why there is a law of secrecy is because wizards were persecuted by Muggles, that is, ordinary people at that time, which led to the emergence of the law of secrecy. Then the wizards hid themselves!" Eisen said and felt in his heart. Somewhat speechless.

To be honest, Eisen also felt that it was very outrageous to mention the "International Wizarding Federation Secrecy Law".

Because ordinary people who don't know magic can actually persecute wizards who know magic to the point where they need to keep their identities secret to survive.

It's like a group of unarmed ordinary people forced some people with magic weapons into a desperate situation and had to hide the magic weapons and pretend to be ordinary people.

"But, doesn't the wizard know magic?" Ivey looked at Aisen in surprise.

"Uh, I'm not sure! Maybe it's because some wizards are very poor!" Eisen guessed.

Not to mention, the possibility that Eisen mentioned is very high.

Like Lockhart, he's not much worse than a Muggle except he's good at Oblivion.

So, if there are enough Muggles and they swarm them, someone like Lockhart, who has no real ability, probably won't be able to stand it.

"You mean some wizards are just magic apprentices?" Ivey said with interest.

"Magic apprentice?" Eisen couldn't help but raise his eyebrows, "You can almost say that! Some wizards are not proficient in mastering their own magic power."

The two asked and answered questions, and bursts of laughter came from Ivy's mouth from time to time. With Aisen's introduction, a wizarding world hidden in the Muggle world was revealed in front of her.

After dinner in the afternoon, the two continued to talk.Perhaps because of his first exposure to magic, Ivy was very excited.After Jeff returned home from the company, Eisen also revealed things about the wizarding world.

Seeing that his son was actually a wizard with magic, Jeff, like Ivy, went from disbelief to surprise, and then to extreme surprise.

In just a few days, Aisen's parents' outlook on life was baptized.

It is even said that Jeff has not gone to work at Eisen Film and Television Company for several days. Instead, he has been talking to Eisen at home, wanting to explore the mysteries of magic.

……

Charing Cross Road!
Eisen and his parents were standing by the street, looking at the location of the Leaky Cauldron.

"Eisen, are you sure there is a bar here?" Jeff looked at the bookstore and record store next to him, and asked in a low voice.

"That's right, there is a shop called the Leaky Cauldron here. Because of the Muggle-repelling spell, only wizards can see it!" Eisen said unhurriedly as he watched his parents explore back and forth.

"Do all wizards enter the wizarding world from here?" Jeff looked back and forth and found that the crowd on the street showed no sign of going this way.

"No, but most people who enter the wizarding world for the first time will enter here!" Aisen said with a smile on his face, "How about it? Do you want me to take you in for a walk?"

"Is it okay?" Ivy looked excited.

"Didn't you say that there is an international law of secrecy in the wizarding world? If we go in, there won't be any problems, right?" Jeff on the side thought a little more.

"It doesn't matter, as long as someone in the family becomes a wizard, then family members are allowed to know the existence of the wizarding world!" Eisen explained, "Let's go, take you in!"

Eisen said as he held his parents' hands and walked towards the Leaky Cauldron.

"Wait!" Jeff suddenly spoke with force on his arms.

"What's wrong?" After stopping, Eisen looked at his father suspiciously.

"Are we going in like this?" Jeff pointed to the clothes on his body, "I mean, wizards should all wear magic robes, right? Is it appropriate for us to dress like this?"

"It doesn't matter! Wizards can actually wear whatever they want. It doesn't mean they have to wear wizard robes!" Aisen shook his head and pulled his parents forward.

As if they had crossed an obstacle, Jeff and Ivy felt as if they had penetrated a layer of fog, and then saw Eisen pushing open a black wooden door.

After entering the Leaky Cauldron, there was a burst of noisy noise.

Several old wizards and witches were sitting in the corner drinking in dirty-looking robes, discussing something in a low voice while drinking.

The bar owner was still the same Tom with almost hairless hair. He was bartending at the bar. When he saw Aisen coming in with two people, he was stunned for a moment and then nodded with a smile.

"Tom, long time no see!" Eisen waved and said hello.

"Want a drink?" Tom looked at the two people following Aisen, then raised the cup and gestured.

"No, I have something else to do, let's do it next time!" After saying this, Aisen pulled his parents and walked straight through the bar towards the back.

……

When they came to the small patio at the back, which was empty except for a trash can, Jeff and Ivy seemed to breathe a sigh of relief.

"Is this the entrance to Diagon Alley you mentioned?" Jeff looked around and found that it was a small courtyard surrounded by walls. There were a few weeds next to the trash can, and there was nothing special about it.

"Does a wizard need to cast a spell to open the entrance?" Ivey asked curiously.

"That's right, only wizards can open the entrance to Diagon Alley!" Eisen said as he came to the trash can, took out his wand and pressed it against the stone wall, then turned to look at his parents, nodded and signaled: "Like In this way, count three pieces upward, count two pieces sideways, and then tap three times!"

When Aisen completed the action, Jeff and Ivey saw looks of surprise in their eyes.

The brick struck by Eisen moved quickly, and a hole was dug out in the middle. The hole expanded as the brick moved, and in the blink of an eye, an archway for people to travel appeared.

"Hey! Welcome to Diagon Alley, the famous commercial street in the British wizarding world!" Eisen said, stepping forward to grab his parents who were still in a daze, and walked through the archway.

Stepping on the cobbled streets, Jeff and Ivy followed Eisen and stretched out their hands, as if they were dazzled, and were attracted by everything in Diagon Alley.

"Eisen, Diagon Alley is a gathering place for wizards, isn't it?" Jeff, who was dazzled, suddenly spoke.

"Yes, there are wizard shops on both sides of the street - now, that's the crucible shop over there, selling all kinds of crucibles. For wizards, crucibles are tools used to brew potions." Eisen pointed. Said a self-stirring, retractable plaque hanging next to it.

"Are you still using crucibles at this time?" The surprise on Jeff's face faded, and then a hint of disgust appeared, "Eisen, why do I think this place is so - well, so backward! Is it my imagination?"

"Well, actually you are right!" Eisen did not expect that his father's observation point would be in this place. "Due to the International Secrecy Law, the wizarding world is largely isolated from the Muggle world."

"Isolation? Have they been living here and not going out?" Jeff had a surprised expression on his face.

"Well, how should I put it? In fact, apart from some wizards who are closer to Muggles or like Muggles, other wizards in the wizarding world rarely operate in the Muggle world!" Eisen pondered for a while.

"In other words, because the scope of wizard activities is limited to this circle, the shops and wizards here seem to be stuck in the 17th century, looking very old and shabby?" Ivy on the side took over.

"That's right! After the Secrecy Law came into effect, wizards rarely moved around in the Muggle world!" Eisen said while walking with his parents, "So, the development of the wizarding world seems to have stalled."

"It can be seen that the outside world has entered the Internet age, but here -" Jeff looked at the clothes of pedestrians on the street, then looked at the style of the shops on both sides of the street, shook his head and said, "It seems that it is still stuck in steampunk era!"

"Quidditch Boutique!" Ivy's eyes fell on the window of a store, "Eisen, is that the Quidditch sport you are talking about?"

"Well, the Quidditch boutique sells some props that can be used in Quidditch!" Eisen said with a smile, "Look at those, those brooms are not ordinary brooms, they are flying broomsticks!"

"Flying broomstick? Like the legendary witch's broomstick?" Not only Ivy, but even Jeff couldn't help but get closer.

"Eisen, can you really fly in the sky if you ride on it?" Jeff asked in a low voice, holding Aisen's shoulders.

"Yes, this is a means of transportation for wizards! But - ordinary people can't use it!" Eisen said a piece of news that frustrated Jeff and Ivy.

"That's really a pity!" Jeff and Ivy shook their heads and continued to walk forward with Aisen.

"This is a travel agency? It's strange. Do wizards also need travel agencies?" Ivy asked, pointing to a shop called Horror Tour.

"It's not strange to have a travel agency in the wizarding world, right?" Eisen shrugged.

"What I mean is, if the wizard wants to travel, can he just ride a broomstick?" Ivy said with a suspicious look on his face.

"Riding a broomstick is too ostentatious. If you are not careful, you will be spotted. How about traveling with a travel agency?" Eisen spread his hands.

"Traveling to follow the 'zombie trail', renting a vampire castle in Transylvania, taking a cruise through the Bermuda Triangle..." Jeff looked at the project introduction outside the travel agency and couldn't help but glance at Eisen.

"What? Do you want to experience the wizard's way of traveling?" Eisen looked at his parents in surprise.

"No, I mean, do those really exist?" Jeff asked in a deliberately lowered voice.

"what?"

"Vampires, zombies, these legendary creatures!" Jeff's face was full of curiosity.

Hearing Jeff's question, Ivy was equally curious.

"Well, let me think about it—" Eisen pondered for a while, and slowly revealed: "Vampires, werewolves, ghouls, trolls, mermaids, goblins, unicorns, etc., all exist!"

"It's really unbelievable!" Jeff couldn't help but sigh.

"Eisen, what does a mermaid look like? Is it like the legend? The lower body is a tail with fish scales, and the upper body is a beautiful woman?" Ivy asked enthusiastically.

"Well, that's not actually the case!" Eisen raised the corner of his mouth slightly. "It is said that mermaids living in warm waters are very beautiful and are worthy of the name mermaids, but mermaids living in cold waters are very ugly."

"It's really amazing!" Ivy exclaimed.

"Well, if you have time in the future, I can take you to take a look!" Aisen responded casually and continued walking along the street.

"Ollivander's Wand Shop! Is that the shop where you buy wands?" Jeff pointed to a shop not far in front of him, with an inexplicable meaning in his tone.

"Yes, I bought my wand from this store! Did you see the plaque in front of the store? It says that this store has been established since 382 BC!" Eisen and his parents were in Ollivander's Stop in front of the wand shop.

"How is it possible? Britain didn't even exist in 382 BC. How could this store exist?" Ivey couldn't help but retorted.

"Well, do you think it's possible that when this store was founded, this land was still under the rule of the Romans?" Eisen mentioned a possibility.

"By the way, there is magic in this world, so the history may be very different from the history we once knew, right?" Ivey seemed to have thought of something, and his face became serious.

"History! The history in this world may—" Eisen sneered, and couldn't help shaking his head while speaking.

"History is written by the victors, I think, this is not something difficult to understand!" Jeff is very clear about this.

"Yes, history is indeed written by the victors, but—" Eisen stopped in the middle of speaking.

No way, although this sentence is correct, it seems a little too false for history that can be changed.

"But what?" Jeff looked at Eisen suspiciously.

"But there is magic in this world!" Eisen sighed.

"You mean, the real history is hidden by magic?" Ivey seemed to understand something.

"It's possible, but that's not the point of what I want to say!" Aisen nodded and then shook his head, pulling his parents to continue walking towards the other side of the street.

"So, what's your point?" Jeff laughed.

"Time travel, the magic in this world can allow people to time travel back to the past!" Eisen said softly.

"It's impossible. If we could go back in time, wouldn't it cause a grandmother paradox?" Jeff's face was filled with disbelief!
"Well, I think it's strange too, but wizards do have the means to go back to the past!" Eisen pondered for a moment and frowned slightly.

Before, Aisen didn't think about this, but now when he heard Jeff say it, he felt a little strange.

how to say?Eisen knew before that the world could go back to the past through a time turner, and he also knew that going back to the past could change history.

This is an established fact, so Eisen has always thought so and didn't think too much about it.

But when I heard my father say the term grandmother's paradox, I suddenly realized that even if wizards in this world could go back to the past through magic, the grandmother's paradox would still occur.

Let’s talk about the witch who returned to 1402 and was trapped for five days.

In the era of 1402, the other party intersected with some people and changed the life trajectory of some people. In the end, 25 of their descendants were not "born".

This is the terrible thing about changing history.

Eisen only knew about this before and understood the horror of changing history.But the problem is that Eisen didn't think deeply.

For example, why did this witch who was trapped for five days back in 1402 not change the life trajectory of her ancestors.

So, assuming that she changes the life trajectory of her ancestors so that she is not born in the future, what will happen?

Obviously, if history had really changed, she wouldn't have been born.But if she hadn't been born, how could she go back in time and change history?Isn’t this the grandmother paradox!

Well, take Aisen himself for example.

Now he returns to before 1972 and directly separates or kills his parents. What will happen to him?Will he disappear directly or die directly?Or will he open up a new timeline and enter a new parallel time and space?
Well, no matter what, Eisen would never experiment with himself.

"If there was magic that could go back in time and change history, wouldn't this world be a little too scary?" As if thinking of something, Jeff shuddered suddenly.

"It's okay, don't worry too much! Time travel experiments in this world are basically prohibited and not allowed by the Ministry of Magic!" Eisen organized his language and slowly explained, "After a lot of experiments by the Ministry of Magic, An alchemical creation called the Time-Turner was developed..."

"In other words, ordinary wizards do not have the ability to travel through time and space?" After listening to Eisen's introduction, Jeff breathed a sigh of relief.

"That's right, so we don't have to worry about other wizards going back in time to change history!" Eisen nodded.

……

After a day of shopping in Diagon Alley and satisfying his parents' curiosity, Eisen went back with his parents.

Before leaving, Eisen also bought some books about the wizarding world at Lihen Bookstore.For example, books such as History of Magic, Fantastic Beasts, etc.

The reason why I bought these books was just to let my parents know more about things in the wizarding world.
