I've already become a Hogwarts professor, and the system only just appeared.

"I heard that Snape really gave you guys a hard time in Potions class, and you guys are actually interested in Potions knowledge?" Su Yu continued to tease.

Just when the three little ones were speechless and about to give up, Su Yu suddenly changed his attitude: "Alright, since you love learning so much, I'll agree."

"Really...really?" Hermione stood up excitedly.

"Of course it's true, but you can only take one book, only one!" Su Yu said with a smile, while writing a note for the three of them.

The reason he agreed to the three kids' request was, of course, to see how heartbroken Snape would be when he lost the ingredients for a Polyjuice Potion. He could also train the three kids and get a free Polyjuice Potion for himself—killing three birds with one stone, it was perfect.

After seeing the three little ones off, Su Yu transformed into a raven once more and flew into the Ravenclaw common room, where the little wizards were no longer present.

He pulled five scout guards from his seamless stretch bag and installed one at every angle of the lounge, ensuring there were no blind spots before leaving, hoping these little gadgets could help him find Voldemort's Horcruxes.

After what happened last night, Su Yu returned to his office and was about to continue his experiment when his phone vibrated again. He opened it and saw that it was a message from Feller.

After thinking for a moment, Su Yu remembered that this guy was the scalper he had casually trained back then. However, the two had not been in contact for a long time. Usually, when Feller got goods from the store, he would go directly to Lu Ping.

The message read: "Professor Su, due to the impact of the Avery family's mobile phone store, the phones we are selling at a premium are no longer selling well. If you have time, I would like to discuss my next steps with you."

So that's what happened. Ever since the Avery family acquired the two mobile phone production lines, they have started 24/7 production, and can put more than 1400 mobile phones into the market every month.

In just over three months, the number of wizards in the UK who own a magic phone has exceeded 9000. Although it is not yet the case that everyone has one, people are no longer willing to pay extra to buy one.

Su Yu replied to Feller, "Okay, you can come to Feiyu Magic Mobile Phone Store to find me on Saturday noon."

……

On Saturday morning, Su Yu arrived at the mobile phone store early. While the two ate breakfast prepared by Timo in the office, Su Yu asked:

"Remus, how are the sales of our Magic Phones going lately? Are they still in short supply?"

Lu Ping thought for a moment: "The phones produced every day can be sold out, but by around 2 p.m., there will be no queues left."

"Then do you think we should reduce production?" Su Yu asked with a hint of probing.

Lupin thought for a moment and said, "I think it's not necessary for now. The market in Britain may be close to saturation, but the demand in other European countries is still very high. We can increase the rations for the Farley family."

Su Yu was quite satisfied with Lu Ping's answer, which showed that Lu Ping did indeed have some thoughts on the factory's development.

However, Su Yu did not intend to give all the markets in other European countries to the Farley family, so he said, "The Farley family's share can indeed be increased, but we cannot put all our eggs in one basket."

"Hmm, what do you mean?" Lupin nodded in agreement.

Su Yu said, "I plan to appoint Feller as our sales manager to start expanding into overseas markets and to have at least one of our own directly operated experience stores in wizarding communities in other countries."

Lupin naturally agreed with expanding into overseas markets, but he was skeptical when Su Yu suggested sending Feller to do so.

“Su, forgive my bluntness, but expanding into overseas markets is not so simple. France, Germany, Italy... do indeed have wizarding towns that are similar to Diagon Alley.”

"But the local wizards are not friendly to outsiders, especially some dark wizards. With Feller's level of magic, it will be very difficult for him to protect himself."

Su Yu nodded. In essence, the wizarding world still values ​​strength. If it were just Feller going there, it might have good results in terms of business tactics, but in terms of security, it would inevitably be unsatisfactory.

"If, and I mean if, I could rescue Sirius Black, do you think it's possible for him to become Feller's bodyguard?" Su Yu asked.

Lupin was originally considering whether he could send Teemo out to protect Feller, or have Teemo watch the factory while he accompanied Feller on the trip.

Upon hearing Su Yu's words, Lu Ping immediately forgot all about those things and looked at Su Yu excitedly, asking, "Su, have you already found it?"

Su Yu nodded and said, "That's right, I've found it, the little dwarf Peter who should have died 12 years ago!"

Chapter 105 Peter Pettigrew (Part 1)

"Where is he? Where is that bastard hiding?" Lu Ping was clearly agitated and grabbed Su Yu's shoulder.

"Lu Ping, calm down. More than a decade has passed. Don't rush into the last few days. What we need to do now is ensure that everything goes perfectly," Su Yu earnestly comforted him.

Lu Ping knew Su Yu was right. He slumped back into his chair, took a few deep breaths, and slowly calmed his heaving chest.

"Where is he?" Lupin asked again.

Su Yu said, "It's inside Hogwarts Castle!"

Lupin nearly jumped up again, but he controlled his emotions: "Are you sure?"

"You should be familiar with this, right?" Su Yu smiled and took out a folded, thick parchment from his pocket.

Lupin, of course, knew about the Marauder's Map. He took the parchment from Su Yu, tapped it with his wand, and said, "I solemnly swear that I have done nothing good!"

Su Yu helped him quickly search, and soon they found a name next to Harry's trio: Peter Pettigrew.

"He, he's with Harry Potter, this..." Lupin was startled. In an instant, countless possibilities surged through his mind, all of them depicting Peter Pettigrew killing Harry Potter.

Su Yu immediately understood Lupin's concerns and explained, "Don't worry, that guy didn't intend to stay by Harry's side. In fact, he's been hiding in the Weasley family for the past ten years, living as their pet."

"So I've already contacted Arthur Weasley, and we're going to the Weasleys' house this afternoon!"

“We can go now!” Lu Ping was clearly impatient. “I can hand over the things at the shop, so it definitely won’t be delayed.”

“Remus, I think you should control your emotions first. We only have this one chance. If he gets away, I don’t think we’ll ever be able to catch him again.” Su Yu waved his hand and continued:

"And I also have an appointment with Feller today. I need to assign him a new task. If you're in a hurry, you can go to Dumbledore first and apply for an admission certificate! Also, help me think of a way to persuade Sirius!"

“Okay!” Lupin nodded. He understood that Su Yu was right. If Little Star escaped again, for example, into the Forbidden Forest, the chance of finding him again would be like finding a needle in a haystack.

Not long after, Feller arrived. By this time, he had changed a lot in terms of both his mental state and his appearance. He had lost some of the decadence of the lower class and gained more of the shrewdness and business acumen of a businessman.

Upon seeing Su Yu, Feller was still somewhat nervous, after all, his fate was entirely in the hands of the man before him. He bowed respectfully to Su Yu.

"Professor Su Yu, it is an honor to see you again!"

"Don't be so polite, tell me your thoughts first!" After all, it was Feller who contacted him, so he still wanted to hear the guy's ideas.

Feller said, "Professor Su, it's no longer feasible to sell the Magic Phone at a higher price in the UK. Most people already own the Magic Phone, and those who haven't bought one yet are simply not rich enough Galleons."

"It's simply impossible to buy these at a higher price on the secondary market, but in other European countries, the Magic Phone remains a very sought-after product."

“I have a connection that can send our magic phones to France, but I know that the magic phones in other European countries are currently authorized to the Farley family by you, so…”

Feller didn't finish his sentence, meaning that he didn't dare smuggle the magic phone to France without Su Yu's authorization.

Su Yu was quite satisfied with Feller's attitude; at least Feller's loyalty was the highest so far.

So Su Yu asked, "Besides France, do you have any other channels in other European countries?"

"Um... well... that's all!" Feller said somewhat awkwardly.

"Here's what I'm going to do. I'll give you a task. Over the next month, I need you to travel to various European countries and investigate local wizarding towns. Our next goal is to open at least one of our experience stores in each country."

Su Yu's words made Feller's head buzz: No, I just wanted to smuggle some magic phones into France, how did you end up arranging for me to inspect various European countries?

"I...I...Can I do it?" Feller asked uncertainly, pointing to himself.

"It'll be fine, don't worry. Go back and prepare these next couple of days, and I'll find you a bodyguard later," Su Yu said, patting Feller on the shoulder.

"Okay, Professor Su!" Hearing that there were bodyguards, Feller breathed a long sigh of relief. That was exactly what he was worried about. In a foreign country where he was unfamiliar with the place, if a local black wizard buried him, no one would know.

After seeing Feller off, Su Yu and Lupin used the Floo Network to arrive at the Weasleys' house.

Generally, access to FiloNet requires authorization from the other party. Previously, users needed to go to a public FiloNet service point to use FiloNet.

For example, the public service point in Diagon Alley is at the Leaky Cauldron, the public service point in Knockturn Alley is at Borgin Burke, and the public service point in Hogsmeade is at the Three Broomsticks.

But things are different now. With the Magic Phone, when using FlooNet, you can simply greet the other side with your phone and arrive directly.

"Sue, Remus, you're here! Please sit down, I've prepared some food!" Molly warmly hugged the two of them.

She already knew Lupin, and since they started working at the Magic Phone store this semester, their relationship was naturally quite close.

Arthur poured Su Yu and Lupin some fine butterbeer. Since Molly started working, the Weasleys' financial situation had improved significantly, and they were no longer as strapped for cash when entertaining guests.

"Arthur, we've come here today because there are some things we'd like to discuss with you!" Su Yu said, sitting down first.

"Oh, what is it?" Seeing Su Yu's serious expression, Arthur also became serious. He was still very grateful to Su Yu.

Ever since Su Yu said he would help him improve his reputation in the magical world, he has been making headlines on Toutiao (a Chinese news and information platform) from time to time these past few months, and he is now doing very well in the Ministry of Magic.

Su Yu and Lu Ping exchanged a glance and said, "Arthur, as far as I know, Ron's pet is a mouse. This mouse must have been in your house for a long time, right?"

Arthur didn't know why Su Yu would suddenly ask this, so he said, "Oh, yes, let me think, Banban was originally a pet we bought for Bill at the pet store."

"Later, Bill gave it to Charlie, who then gave it to Percy after graduating, and Percy gave it to Ron. It's been with our family for about 11 years now."

"Arthur, do you think an ordinary mouse can live for 11 years?" Lupin then asked.

Chapter 106 Peter Pettigrew Part 2

Arthur Weasley stared blankly at Su Yu. He had never thought about or cared about how long a rat could live, but now that Su Yu had suddenly asked him this question, he was dumbfounded.

"I guess... I think so..." Arthur replied uncertainly.

Su Yu gave the standard answer: "The lifespan of an ordinary mouse is about 1-2 years, and if it lives longer, it may reach 4 years, but the only mouse in the world that can live for more than 10 years is probably your family's Banban."

"Could it be that Banban isn't a rat? Or is it some kind of magical creature?" Molly arrived at the table with fish and chips, just in time to hear Su Yu's words.

Lupin was speechless and retorted, "Molly, don't you know whether it has magic or not?"

Molly thought for a moment and nodded, "That's right, it doesn't have any magic, it's just an ordinary mouse, so what's going on?"

Unlike Molly's carefree attitude, Arthur had already realized something was wrong. He took the food Molly offered him and said seriously, "So there's something wrong with Scabbers, right?"

Su Yu nodded and continued, "Do you remember anything special about Banban?"

Molly thought for a moment and said, "Ah! I know, it's missing a finger on its right hand!"

“It’s the index finger, right?” Lupin asked.

“That’s right, it’s the index finger!” Molly gave a definitive answer.

Su Yu continued, "If that's the case, then there's no mistake. We suspect that your Banban is actually an Animagus form of a wizard."

"Oh! Sue! You're not kidding, are you?! How is this possible? Scabbers has lived with us for over ten years. No wizard can maintain an Animagus for over ten years!" Molly was genuinely shocked, and her voice rose several octaves.

But Arthur had begun to believe Su Yu. His face was ashen as he asked, word by word, "Who is he?"

“Peter Pettigrew!” Lupin said through gritted teeth.

“Impossible, absolutely impossible. That chubby child is dead. He died 12 years ago. I remember the newspapers saying he was blown to bits, leaving only a stalk…” Molly stopped speaking, suddenly realizing something.

Lupin continued, "That's right, he didn't leave a body, only an index finger, the index finger of his right hand!"

With a bang, Arthur slammed his hand on the table and stood up. At this moment, he was completely different from the amiable Arthur he usually was: "What is his purpose in coming to our house?"

Molly also snapped out of her shock and stood up, exclaiming, "Oh my god... if that's the case, Ron is still with him. Won't Ron be in danger?"
