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

……

The audience below was making a racket, but the highest they reported was 200 miles per hour, and they were even laughed at. Su Yu pulled him up and said:

"Not bad, young man, you have a great imagination. Since your guess of the speed is closest to that of our Feiyu 001, I've decided to give you a Feiyu high-end mobile phone!"

There was an uproar, and many wizards beat their chests in regret, blaming themselves for not daring to report the exaggerated figure of 200 miles per hour.

The winner was overjoyed, but also inwardly astonished. He had been talking nonsense, but he never expected that Fei Yu could actually do it. 200 miles per hour, that was just too exaggerated.

Su Yu's tricks were all learned from Lei Jun in the future. Seeing that the audience's emotions had been stirred up, Su Yu said, "Then let me announce that the cruising speed of Feiyu 001 is 300 miles per hour!"

"Wow!" Another uproar erupted, and the noise at the scene grew even louder. That's 300 miles per hour, which is nearly 500 km/h in metric units. It would take only two hours to cross the entire UK. That's just too outrageous.

What they didn't know was that this was technology from ten years ago. Su Yu's latest technology could now increase the speed of the magic car to around 1500 km/h.

Seeing that the audience had finished their discussion, Su Yu decided to continue with Lei Jun's comparison technique. He pressed his hand down to quiet the audience, and then continued, "Would you like to own such a wonderful magical car?"

"miss you!"

Do you want to know its price?

"2000 Galleons!"

"Who said 2000 Galleons?" Su Yu feigned anger. "Aren't you here to cause trouble? Let's first look at the benchmark in the flying broom industry, what's the price of the Nimbus 2001?"

"That's right, it's 500-800 Galleons!"

Su Yu remained calm and continued, "Then let's take a look at the price of the world's fastest flying broomstick, the Firebolt. That's right, 3500 to 5000 Galleons!"

"Our magic car is both more comfortable and faster than a fire bolt. What do you all think it should cost?"

This time, the shouts below noticeably subsided. The ordinary wizards understood that this vehicle was far beyond their means. After a long while, someone finally shouted, "8000 Galleons!"

Su Yu looked at him, smiled without saying a word, then looked around at everyone and said firmly, "Our price will be 3500 Galleons!"

This time, the audience's gasps were even louder than before, although 3500 Galleons was still not something an ordinary wizard could afford.

But after comparing the Nimbus 2001 with the Firebolt, the price seemed incredibly cheap to the average wizard.

The product launch event ended quickly and was very successful. The video of the event will be featured on Toutiao tomorrow morning.

In fact, Su Yu thought about the pricing of Feiyu 001 for a long time and finally set it at the 3500 level, which could satisfy the needs of nobles and give ordinary wizards some room for imagination.

Moreover, at this price point, his profit is still over 1000 Galleons. He plans to launch a more affordable version for around 500 Galleons and a high-end version for around 10000 Galleons, making magical cars a standard feature in the magical world.

After finishing up at the Feiyu Experience Store, Su Yu quietly left Hogsmeade. He had one more thing to do, something he had promised at the beginning of the school year.

Driving his Bentley, Su Yu had another person in the car, Sirius Black. The man looked displeased and said, "Why won't you let Harry live with me? I'm his godfather."

“What’s the use of telling me all this? I’m just a professor. If you want to change things, you have to talk to Headmaster Dumbledore,” Su Yu said helplessly.

Since the video of Sirius and Amelia was filmed, the two have gotten along much better. Neither of them would take the initiative to make fun of the other, lest the other get angry and unleash their ultimate move.

Upon hearing Dumbledore's name, Sirius's momentum immediately wilted, and he continued to ask, "So what is my identity today?"

"Don't worry about the boss behind Avery Properties. I've already spoken to the Avery family. Just give their general manager a call, and they'll give Uncle Harry a £300 million deal." Su Yu explained the plan again.

Sirius was still a bit annoyed. He had heard a lot from Harry about how his aunt's family had abused him, and now, as Harry's godfather, he not only couldn't take revenge, but also had to send them a sum of money. The thought of it made him feel very frustrated.

So he continued, still annoyed, "If I were younger, I would have turned Harry's aunt and uncle into pigs and made them stay in the pigsty for a few days."

As they talked, the two arrived at Privet Drive and parked the car in front of the Vernon family's yard.

Chapter 161: Why has the plot taken another turn? (Part 2)

Harry returned to the Vernon family on the second day, and he found that his Uncle Vernon's attitude towards him was a bit strange, always seeming to want to say something but holding back.

Finally, during dinner that evening, Uncle Vernon asked, "Harry, who exactly was the person who came to our house last year and took you away?"

“That’s Professor Su Yu from our school.” Harry didn’t know what Uncle Vernon was up to, but he answered truthfully nonetheless.

Uncle Vernon nodded and then asked, "When you came back, didn't he ask you to give me a message or anything?"

Harry shook his head: "No."

At this moment, Aunt Penny said from the side, "Don't even think about that so-called promise. Those... weird people are from a completely different world than us."

“But…that’s Avery Construction Company, if I could…” Uncle Vernon sighed and didn’t continue.

Since Su Yu left with Harry, Uncle Vernon has been looking into Avery Corporation and found that the company is really strange. Whenever they encounter some business difficulties, their competitors will inexplicably encounter some accidents.

This made Vernon both scared and expectant. After Harry returned this time, he no longer dared to beat and scold Harry as recklessly as before.

He learned a lot about the wizarding world from Penny and understood that wizards have laws to protect ordinary people like him.

Therefore, although Uncle Vernon was somewhat afraid in the past, he was always very tough when dealing with wizards.

But after learning about the Avery Company, Uncle Vernon realized that even without magic, the wizarding family could easily deal with him.

Just as Uncle Vernon was about to give up asking, the doorbell rang. Uncle Vernon got up to open the door and was surprised to see Su Yu, whom he had just been talking about.

“Mr. Vernon, I am Professor Su Yu from Hogwarts. It’s a pleasure to see you again!” Su Yu greeted him first.

“My name is Black, and I’m also a professor at Hogwarts.” Standing behind Su Yu, Sirius Black said with a displeased look, his eyes scanning the Vernon family’s situation, which at least from the outside, seemed quite ordinary.

"Professor Sue! Sirius! What brings you here!" Harry ran out at that moment, shouting excitedly.

Su Yu quickly gave Harry a wink and said, "Professor Black and I came to see how you are doing. After all, you have suffered a lot before. As Hogwarts professors, we have a responsibility to ensure the healthy growth of our students."

"Come in and have a seat!" Uncle Vernon quickly extended an invitation.

Su Yu and Sirius Black then came in and sat on the sofa. Su Yu then said, "Mr. Vernon, let me introduce you. This Mr. Black is not only a professor at Hogwarts, but also one of the behind-the-scenes bosses of Avery Construction Company."

"He came today mainly to check on your family's situation. If there are no problems, he will fulfill the promise I made to you before."

Upon hearing the word "promise," Uncle Vernon's face immediately lit up with a smile. "I see," he said, "Mr. Black, shall I show you around Harry's room first?"

“We’ve renovated his room. Why don’t I take you up there and show you around?”

Sirius Black acted like a leader going down to the grassroots level, following Vernon with an air of authority, and finally nodded in a perfunctory manner: "Not bad, I'm very relieved that Harry is growing up in your family. In that case, we'll take your company's products."

As he spoke, Sirius Black pulled out a cell phone—a Muggle phone, which Su Yu had just given him. He dialed the only number on it.

After a few perfunctory chats, he handed the phone to Uncle Vernon: "This is the general manager of Avery Construction Company. You two exchange contact information. I won't get involved in what happens next."

"Yes, yes, thank you so much!" Uncle Vernon beamed and immediately took the phone from Sirius Black and started chatting with the person on the other end.

As Su Yu left, he could tell that in Uncle Vernon's eyes, Harry Potter, his nephew, was probably closer than his own son.

With Harry's matter settled, Su Yu felt a great sense of relief. Thinking about Sirius Black, the main villain in the original storyline, who was currently with him, he imagined that his life next semester would be wonderful and pleasant.

What I need to do now is continue to build up my strength and raise my magic, polymorph, and alchemy skills to at least LV11 before Voldemort returns. That way, I'll be able to put myself in a fighting position.

In high spirits, Su Yu took Sirius home and then drove at breakneck speed all the way back to New York City.

This time, since Chen Ying was going to patrol the streets that night, Su Yu went back to his Feiyu Modification Shop first and cleaned up the house.

The previous times he came back, he stayed at Chen Ying's place, and each time it was the girl who took the initiative. Her disguise skills were superb. This time, Su Yu planned to give the girl a surprise attack.

So he first prepared some candles, whips, collars and the like in his room, and then secretly contacted the man under Chen Ying.

After confirming Chen Ying's location and helping her ask Stuart for leave, Su Yu changed his clothes and waited for Chen Ying on her usual patrol route.

After a series of maneuvers by Su Yu, Chen Ying's magical car broke down on the road. While Chen Ying got out to fix the car, Su Yu leaned forward and quickly approached Chen Ying from behind.

Although the man saw Su Yu, he just smiled and seemed to be expecting Su Yu to take his captain away.

As an Auror, Chen Ying had a keen sense of danger. Hearing a sound behind him, he turned around without hesitation and cast a Binding Charm.

Having experienced thousands of duels, Su Yu's perception is now extremely sharp. Before Chen Ying could even see him clearly, he used a small iron armor spell to deflect Chen Ying's binding spell back.

Then, with one hand on Chen Ying's shoulder, he disappeared in a flash. The man, who had been smiling, suddenly realized that Su Yu and the captain were gone, and since he didn't know how to fix cars, his smile gradually froze and then disappeared.

Chen Ying felt a dizzying sensation and found herself thrown onto a bed. Just as she was about to try to resist, she heard Su Yu's voice:

"Officer Chen, do you remember me? You were the one who sent me to prison back then. Now that I'm out, I'm going to repay you a thousandfold for the pain you suffered back then!"

That voice...it's so familiar. This place...it's so familiar too. Chen Ying struggled to turn to the side and finally saw Su Yu's sinister smile. Her eyes changed, and she immediately cooperated, saying:

"No, no, I'm a police officer. The Magical Society will not let you get away with this. My boyfriend is a professor at Hogwarts. He knows Dumbledore. If you dare to do anything to me, he will definitely not let you off the hook."

……

Su Yu stayed in the United States for a full month, playing different roles every day, and was quite content to stay there until one day he saw a news item on Toutiao:

Shocking news: Barty Crouch Jr. and Peter Pettigrew have both escaped from Azkaban, which could be detrimental to Harry Potter.

Upon seeing this title, Su Yu had only one thought in his mind: Wait, how did the plot take another turn?

Chapter 162 Dementors (Part 1)

This summer was probably the most relaxing time Harry Potter had at the Vernon family's house. Uncle Vernon seemed like a completely different person; he not only stopped hitting and scolding him, but even spoke to him much more kindly.

In addition, Sirius Black also bought a house on Privet Drive, only five minutes away from Vernon's house, and Harry would often go to Sirius's house.

Because Sirius Black is an adult wizard, Harry can even practice magic freely here, and even if the Ministry of Magic asks, Sirius Black can say that he cast the spell himself.

That evening, Harry Potter returned from Sirius's house as usual, but for some reason, the temperature was a bit low even though it was summer.

Harry instinctively tightened his collar and looked around. Suddenly, a dark shadow darted past in the distance.

"What is that?" Harry wondered, taking two steps forward to get a better look at it.

The next moment, the dark figure rushed out from behind the tree at an extremely fast speed, and an extremely terrifying face kept growing larger in front of Harry Potter.

His face seemed to be covered by a tattered black cloth, making it impossible to see his features clearly. His eyes and mouth were empty, like an endless abyss.

As the face drew closer, Harry saw it more clearly. It opened its mouth as if to let out a hysterical roar, but Harry couldn't hear anything.

Harry tried to run away, but his legs and feet seemed to have lost all feeling and wouldn't obey him at all. He could only stand there, staring wide-eyed, watching the thing get closer and closer to him.

The shadowy figure passed by Harry. Harry estimated that at its closest, that terrifying face was only ten centimeters away from him. A chilling cold pierced his body and his soul.

The next moment, Harry felt as if his heart had fallen into an ice cave, and he became dejected and depressed, as those happy memories were gradually leaving him.

After they crossed paths, Harry's legs gave way and he fell to the ground with a thud. He struggled to lift his head and saw that the shadowy monster had turned around again and was charging towards him.

"Am I going to die?" That was Harry's last thought. Before he lost consciousness, he vaguely saw a figure stand in front of him, emitting a blazing white light that drove away the monster.

The newcomer was none other than Sirius Black, and he used the Patronus Charm. Countless white streams of light shot out from the tip of his wand, eventually coalescing into a large dog.

The big dog pushed off with its feet and flew up, pouncing on the terrifying black shadow. Others might not recognize it, but Sirius was extremely familiar with it. When he was imprisoned in Azkaban, this thing accompanied him every day; it was a Dementor.

For a long time, Sirius Black had been thinking that if he were ever able to leave Azkaban, he would make those ugly creatures know how powerful he was.
