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

"Don't move! We are Aurors. Put down your wands and weapons. Fighting in the streets of Hogsmeade? I think you want to get into Azkaban!"

Kingsley's words stunned everyone present, including the goblins. Those who weren't quick-witted immediately put down their weapons and wands as Kingsley had instructed.

Those with a sharp mind simply turned and ran. As for why they didn't use Apparition, a wizard who could learn Apparition wouldn't be reduced to being a scalper.

Su Yu had never seen a street fight between fairies and wizards before, but unfortunately it was stopped. However, there was a pleasant surprise: Tonks also came.

The girl was wearing a black dress today, paired with ankle boots and brown curly hair, giving her a mature and sophisticated look.

Upon seeing Su Yu, Tonks immediately broke down in his act, ran over and gave him a hug, saying, "I heard your shop had an accident, it scared me to death, thank goodness you're alright."

Chapter 50 The Americans

Su Yu could feel Tonks' concern for him, so he patted her head and said, "Don't you know how strong I am? I'm not even afraid of vampires, so what's there to be afraid of in this little situation?"

"Really? Then who was it that was carrying me on their back, being chased by the vampire count and running for their lives?" Tonks teased.

"That's definitely not me. I'm the great hero who descended from the sky wearing golden armor, riding on a seven-colored cloud, and rescued you from the vampires!"

You're shameless!

While Su Yu and Tonks were being all lovey-dovey, Kingsley had already arrested several troublemakers, including Feller.

Feller was certainly one of those who were quick-witted, but unfortunately his strength was too weak. He couldn't Apparate, and he wasn't fast enough to run. He was bound tightly by a Binding Curse.

After dealing with these people, Kingsley came to Su Yu and said, "Professor Su, you need to change your shop's sales model, otherwise these people will cause trouble sooner or later."

Tonks immediately became unhappy: "Captain, what does this have to do with Su Yu? His shops are doing business normally, and other shops do the same thing. Why don't other shops have any problems? It's clearly these people's own problem."

Kingsley couldn't help but smile wryly. Tonks was usually fearless on the team, and now she was going to great lengths to protect her old boyfriend.

Fortunately, Su Yu tugged at Tonks: "Okay, Captain Kingsley, I'll think of something else to try and prevent this from happening again."

At this moment, Feller, who was trapped, suddenly struggled and rushed towards Su Yu. The Auror reacted quickly and cast a Stunning Spell, knocking Feller to the ground. But this guy was quite resilient and struggled to raise his head: "Professor Su... I have a way, I have a way to solve the current problem."

After saying that, Feller fainted. Su Yu had heard Lupin mention Feller a few times. Although he wasn't very strong, he was indeed very quick-witted. So he asked Kingsley, "What do you plan to do with this guy?"

Kingsley shook his head: "There's nothing to do. He's not a dark wizard. At most, we'll just take him back and lock him up for a couple of days, give him a verbal warning."

Su Yu's eyes lit up: "Then I wonder if this person can be handed over to me directly?"

"Su, what are you doing? Although this guy did disrupt the order in your store, you can't use vigilante justice on him!" Tonks pulled Su Yu aside and warned him in a low voice, afraid that he would do something reckless.

Su Yu chuckled: "What are you thinking with your little brain? I think this kid is quite smart, and I want him to do something for me."

The two chatted for a while longer. Kingsley then led his men to take away everyone else they had captured. As for Feller, Kingsley was very accommodating and left him with Su Yu.

Su Yu had Lupin and Timo take the guy back to the shop and treated him with a healing spell. Feller woke up quickly.

Upon realizing that he hadn't been taken away by the Aurors, Feller instantly understood what was going on. He quickly stood up and bowed to Su Yu, saying, "Respected Professor Su, thank you very much for your help."

“Actually, I’ve known about what you’ve done for a long time, and I have ways to deal with you, but I haven’t done it. Do you know why?” Su Yu asked casually while drinking the tea that Timo brought him.

Feller understood that this was his chance to change his life. His mind raced as he organized his thoughts and said, "Professor Su, your decision has a profound meaning. I can only make some guesses based on my limited perspective."

"You're not punishing us because you want us to continue selling the magic phone at a higher price on the market. This way, people will appreciate how rare the magic phone is and more people will want to buy it."

The concept of scarcity marketing doesn't exist in the wizarding world, but Feller's analysis is actually quite close.

Su Yu originally had no intention of engaging in any scarcity marketing, but since scalpers had appeared in the market, he didn't mind taking the opportunity to establish the high brand value of the Feiyu Magic Phone.

Of course, this kind of thing can't be done indefinitely, otherwise it will only backfire in the end. Su Yu's plan is to add one or two more production lines during this summer vacation. Before that, he can let Feller continue to work as a scalper for a while.

Su Yu nodded: "That's right. Starting today, Feiyu Mobile Phone Store will use a real-name registration system for purchases. Once a wizard has made a purchase, they will not be able to make another purchase within three months."

Upon hearing this, Feller immediately became anxious and was about to speak when Su Yu raised his hand to interrupt him: "Don't be in such a hurry. Starting today, you can take 10 mobile phones directly from our store every day, but the price is 55 Galleons. Are you willing?"

"I do, I do! Thank you so much for your generosity, Professor Su!" Feller was overjoyed and immediately prepared to present Su Yu with the most honorable wizarding gift.

Su Yu waved his hand to stop him: "Alright, since you're willing, let's make a vow that our deal cannot be revealed to anyone else!"

"Don't worry, Professor Su, I will keep this to myself!" Feller assured him.

Su Yu wasn't necessarily after those 5 Galleons; he mainly wanted to assess Feller. If he proved to be a capable individual, he might consider making him the CEO of his company in the future.

After Feller left, Su Yu checked the recent accounts in the shop as usual. The little elf Teemo had prepared a sumptuous lunch for him and Lupin, and the two chatted while eating.

Lupin is a completely different person now. He's wearing a new, well-fitting suit, looks much more energetic, and has even gained weight.

"How are things going? Are you satisfied with working in the factory?" Su Yu asked.

"Very satisfied. To be honest, I haven't had such a comfortable life in a long time since James and the others left!" Lupin cut the steak on his plate and chewed with relish.

"Just tell me what you need, and I'll do my best to meet your needs. And Timo, you can ask for anything you want," Su Yu said.

"Teemo has no demands. Teemo is doing very well here. Teemo is willing... to serve you forever!" Teemo hesitated for a moment, but still did not say that he wanted to acknowledge Su Yu as his master.

Su Yu wasn't in a hurry. At this moment, Lupin said, "Su, my biggest hope right now is to find Peter Pettigrew as soon as possible. If he is really still alive, then Sirius Black was wronged and shouldn't be in Azkaban."

After hearing Su Yu's analysis, Lupin felt increasingly uneasy. Sirius, with his personality, would never betray James, even if it meant death.

Peter Pettigrew, however, only has a broken little finger left, which is completely illogical. Whenever he thinks about this, he can't wait to find out the truth and rescue his old friend.

Su Yu said, "Lupin, I know you're anxious, but don't rush. If it's true, as we suspect, Peter Pettigrew is hiding in some wizard's house."

"Then we only have one chance. Once he finds out, he will most likely leave the wizarding world for good. Then it will be a pipe dream for you to find him again."

Lupin nodded. He understood that Su Yu was right; this matter should not be rushed. But what he didn't know was that Su Yu wasn't in a hurry simply because he wanted his lifelong enemy to suffer a few more days in Azkaban, since Su Yu had always opposed him in the past.

"By the way, has anyone in the US contacted you? When are they coming to pick up the second batch of goods?" Su Yu changed the subject.

"It'll be today, probably in a little while!" Lupin explained.

As the two were chatting, the shop door was pushed open, and two people walked in, a man and a woman. The man was a man, and Su Yu recognized the woman; it was Chen Ying!

"Yingzi! What brings you here?" Su Yu sat up abruptly, feeling inexplicably nervous. She quickly used the spell ring on her finger to cast a cleansing spell on herself, since Tonks had hugged her that morning, and women's noses are always very sensitive.

"What, aren't you welcoming me?" Chen Ying asked with a smile, looking around the shop as she walked.

Lupin immediately realized something was wrong and asked, "Su, who is this?"

“Chen Ying, an Auror from the Magical Congress of America, is my good friend. This is Remus Lupin, the factory manager of our mobile phone factory and also the person in charge of this store,” Su Yu introduced to the two.

“I know, I contacted Mr. Lu Ping before I came. You sit down and eat your meal, I don’t need you to entertain me!” Chen Ying said casually, walked behind Su Yu, put her hands on Su Yu’s shoulders and pressed him down on the stool.

"Have you had lunch yet? If not, I'll have Timo bring you another serving; his cooking is excellent." Su Yu sat down casually and continued eating his steak.

"Teemo? Is that the little Pokémon you were talking about? Then give us one. It took us almost 10 hours to drive here," Chen Ying said, somewhat tempted.

"Ten hours? You guys aren't still using that car from five years ago, are you? Tell old Stuart to order my latest product. It can run a trip in five hours and only costs 5000 Galleons." Su Yu didn't forget to promote his product.

Chen Ying pouted: "Don't you know what kind of person Old Stewart is? It's good enough that he's usable. Expecting him to provide us with new equipment is like expecting you to give me a car instead."

“Of course I can give you a car, but it’s a private car, you can’t drive it when you’re on a mission! He still has to buy it. Congress will pay for it, why would he be stingy?” Su Yu pretended not to understand the implication in Chen Ying’s words.

"You two are both so stingy!" Chen Ying said irritably.

Su Yu was indignant, but he didn't want to reason with an angry woman, so he asked, "How are the Magic Phones selling in the US?"

“The last batch of goods you provided sold out in three days. This batch of Stuarts was exclusively supplied to Congress. Congress’s intention is to prioritize providing one unit to every employee,” Chen Ying explained.

Su Yu couldn't help but sigh, "Old Stuart really knows how to do things differently. He just equipped all the congressional staff with that, and that single-handedly took over half a year's worth of sales."

However, Su Yu still had a question: "You mean, the Magic Congress will provide each of you with a magic phone, for free?"

Chen Ying said, "How could that be? This thing would sell for $350 in the US, but internal staff can get a 5% discount."

Su Yu's eyes widened, and his voice suddenly rose several octaves: "How much did you say? 350 Zhuoguo? If I remember correctly, the exchange rate between Zhuoguo and Gold Galleons is 3.5:1 recently!"

Chen Ying had already seen the price of the magic phone in Su Yu's shop, but she wasn't too surprised: "You sell it for 50 Galleons here. If you go to the United States, there are a series of tariffs, so it's normal for the price to double."

If you put it that way, it does seem pretty normal... my foot! Old Stuart got his stock from Su Yu for 35 Galleons apiece, but sold it for 350 Zhuozhou pots in America, which is equivalent to 100 Galleons.

So, Stuart earns more than Su Yu. It's hard to tell who's working for whom. But when the agreement was signed, it was stated that Su Yu wouldn't care about Stuart's selling price; whatever price he made was his own business.

After having lunch together, Chen Ying packed all the goods into seamless stretch bags and then toured the entire factory with Su Yu.

Chen Ying really liked Timo, and they even exchanged messages on Feixin (a Chinese instant messaging platform). Then she asked, "Do you usually live here?"

“I don’t live here. I usually live at the school, where there are faculty and staff dormitories!” Su Yu said.

"Can you take me to see it? This is the famous Hogwarts. I've never been to any other magic school except for Ilfamoni!" Chen Ying looked at Su Yu with some anticipation.

"Of course, no problem. I happen to have a class this afternoon. Would you like to come along?" Su Yu used a tactic of feigning retreat to advance.

"Okay, let's go quickly then. Hey you, wait for me here. We can go to the village bar to have some fun!" Chen Ying instructed her partner, then pulled Su Yu's hand and walked out.

Su Yu's smile froze on his face as he asked, "I remember you said before that the class you hated most when you were in school was Muggle Research, right?"

Chen Ying nodded: "Yes, but I don't hate the course. I just hate our old professor. He talks about outdated things from the last century, but he insists that he is right."

"As you know, Ifamoni's Muggle Studies course is a required course because American Muggles and wizards have a very bad history of interaction, which has led to a serious prejudice against Muggles among the older generation of wizards."

"So every time I listen to his lectures, I feel a disconnect, but you are different. Your lectures are always very interesting."

Chen Ying held Su Yu's hand, her eyes shining. Su Yu said, "Wait a moment, there's something I forgot to tell Lu Ping."

After saying that, Su Yu returned to the store and called Timo over, saying, "Go and tell Jingjing to clean up the room where Tonks stayed, make it look brand new."

Lupin looked at Su Yu with concern, and after Su Yu stood up, he pulled him back and said earnestly, "Tonks is a good girl!"

"I know!" Su Yu said helplessly.

"It's good that you know, but don't let her down!" Lu Ping's tone sounded like an old father lecturing his philandering son.

"Don't worry, I never let a good girl down!" After saying that, Su Yu turned around and left, taking Chen Ying with him and teleporting to the outside of Hogwarts.

Extra Chapter: Timo's Blind Date (Free)

"Hurry up, Teemo, stop dawdling!" Su Yu walked ahead, and they were almost at Hagrid's hut.

Timo followed behind Su Yu, his expression quite complicated. He would occasionally touch his butler's suit, checking for any wrinkles.

"Professor Su... Timo... is a little nervous!"

"What are you so nervous about, you're a boy? Hurry up, stop dawdling, people are getting impatient!" Su Yu continued to urge.

"I...I...I've never seen a female elf other than my mom before!" Timo said again.

In fact, even his mother, Timo's memory is very vague. He was sold to the Anthony family when he was three years old and grew up with little Anthony.

"Hey, what's the big deal? Just think of it as making friends. It doesn't have to be anything between you and the other person. Relax," Su Yu comforted her.

As they spoke, the two arrived at the door of Hagrid's cabin. After knocking, Hagrid quickly came out with a beaming smile and said, "Sue, you're finally here! I couldn't wait any longer!"
