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

Su Yu looked at Gemma Farley: "Gemma, take out your magic phone."

“Okay, Professor.” Gemma Farley took out her phone and placed it on the table.

Su Yu drew his wand, chanted a spell, and the phone screen lit up. Countless silver threads sprayed from the tip of the wand, wrapping around Gemma Farley's phone.

The threads eventually converged on the screen, forming a new icon—a raven's head pattern with the words "Raven's Feather" written below.

After finishing this task, Su Yu took out four more magic phones and sent them to George, Fred, Cedric, and Alice respectively.

Under Gemma Farley's guidance, the kids added each other as friends, and Su Yu created a group chat called: Raven's Feather.

Once everyone was familiar with the basic usage, Su Yu explained, "These icons on the phone are what I call application software. They work with the Magic Phone to achieve various functions."

"For example, Fetion can enable real-time communication, the camera can activate the phone's camera to take pictures, and the album can view pictures and videos stored on the phone."

"These are all achieved by using the most basic magic runes to guide magic power, and then through the magic corridor within the magic phone."

"And this Raven's Feather, which I call developer software, can only be used by members of our Raven's Feather. With it, you can arrange these basic magic runes and develop other different application software."

"The instructions are included. You can study them on your own when you get back. I believe that with your intelligence, you will be able to master them quickly. If you have any questions, you can ask me anytime."

Turning to George and the other two, he said, "Your first development project, which is also Ravenfeather's first official project, aims to bring Wizard Chess into the Magic Phone."

"Imagine what it would be like to play Wizard Chess with a friend thousands of miles away using a magic phone?"

"The timeframe I'm giving you for this project is until the end of this academic year, which is about 7 months. Gemma and Alice will be assisting."

"This is a test for the five of you. If you pass it successfully, I will take you as my disciples, so good luck!"

Upon hearing Su Yu's hypothesis, the three boys' eyes lit up. Although they didn't particularly like Wizard's Chess, developing Wizard's Chess and playing Wizard's Chess were completely different concepts.

The five children were extremely excited about becoming Su Yu's disciples. The resources a disciple of an alchemy master could obtain in the magic world were simply too numerous.

Seeing how eager they were to try, Su Yu quickly added, "Of course, this project will be completed in your spare time."

“If any professor comes to me to complain that you have not completed your assignments on time, or that your grades have fallen out of the top 20% of the year in the final exams, then I will suspend your privileges.”

"Ah~" The children immediately lowered their heads.

Su Yu's first condition is not difficult; there are many ways for them to complete their homework. However, the second condition is not so simple, which means that the spare time they can spare will be very limited.

Su Yu clapped his hands, drawing the young wizards' attention back to him, and said:

"Finally, this is a benefit for Ravenfeathers. Starting today, you can pre-order magical phones at the school. For Hogwarts students, we can offer a discounted price of 45 Galleons per phone."

"Furthermore, you will receive a commission of 5 Galleons for every unit you sell, but this offer can only be given to each student once."

"Yay, long live Professor Su Yu!" The children's previously low spirits were reignited, and they left happily.

No one could have imagined that "Raven's Feather," which would later wield immense influence in the global wizarding world, would be so hastily established in a professor's office at Hogwarts.

“Su, there’s something I have to remind you of,” Tonks suddenly said as the children walked away.

"What is it?" Su Yu asked curiously.

“Back when we were in school, if we wanted to start a new club or organization, we had to report it to the school in advance, usually to the dean of the college.” Tonks pointed to the raven ring on his hand.

Su Yu slapped his forehead and said, "I've been so busy lately that I forgot about it. I'd better go see Headmaster Dumbledore directly."

Su Yu made this choice because Old Deng was far too suspicious. Although he had dealt with the giant last time and his identity was temporarily safe, Su Yu was still worried about him.

But if Dumbledore suspects that he, like Voldemort, is forming a clique at school and conducting dark magic experiments, then he will be in big trouble.

Arriving at the principal's office, Su Yu recited all the products from Honey Duke Candy House in front of the statue, but the taste instructions were still wrong.

Just as Su Yu was about to take out his phone to send a message to Dumbledore, a sudden idea struck him, and he said: "Little White Rabbit Milk Candy."

The next moment, the statue moved, revealing the stairs behind it. It seems the principal really liked the Chinese milk candy I gave him last time. Next time, I'll bring him some soda so he can experience the joy of the Muggle world.

The moment the password matched, Dumbledore knew someone had arrived. When Su Yu came in, he asked with a smile, "Su, did you come so late to deliver my magic phone?"

Su Yu rolled her eyes: "No, Professor, I must keep my promise. The magic phones sold must be delivered to customers the day before Christmas."

“But as far as I know, some students at the school have already received them.” Dumbledore raised an eyebrow, indicating that you can’t fool me, kid.

Su Yu explained, "Those weren't for sale. I'm planning some collaborations with the Farley family, so I gave the child a few phones."

Dumbledore seemed thoughtful, then asked uncertainly, "The Farley family? So you want to sell the Magic Phone to other European countries? But why not partner with a more powerful family?"

Su Yu waved his hand: "Are you talking about the 28 pure-blood families? We are still just a small workshop. With the way those old noble families act, they will definitely want to take the lion's share. I would rather they come to me on their own initiative."

Dumbledore gave Su Yu an approving look: "A wise choice. So what brings you here today?"

“I started a club at school called Raven’s Feather, and our purpose is…” Su Yu repeated the words he had just used to fool the children.

But clearly, Dumbledore, the old man, wasn't as easily fooled as those youngsters. He tapped the table lightly with his fingers and asked a crucial question: "You mean it's established, not just about to be established?"

Su Yu had no choice but to explain, "I'm sorry, Professor, I've been too busy lately. I forgot that I needed to report to the school. Tonks reminded me just now, and that's when I remembered."

Dumbledore nodded, seemingly without doubt, and then asked, "Who are the current club members?"

“Gemma Farley, Alice Lavia, Cedric Diggory, and the Weasley twins,” Su Yu answered truthfully, since these children would all be wearing raven rings, making them easy to spot.

"You have a good eye. Have you considered bringing Harry Potter into your club as well?" Dumbledore suddenly suggested, changing the subject.

"Is it okay?" Su Yu wasn't opposed to it, after all, Harry's talent was quite good, especially in combat.

“Of course, if you’d like,” Dumbledore said.

Su Yu quickly calculated in his mind that Dumbledore's sudden desire to include Harry meant that he had likely accepted his good status and wanted him to become part of Harry's protection.

This is advantageous to me, at least in recent years. Not only can I get Dumbledore's help, but I can also use Harry's reputation to expand my own prestige.

But in the long run, he would have to stand on the opposite side of Voldemort. Since he was already on the opposite side of Voldemort, what was there to hesitate about? So Su Yu said:

“Okay, I will put him through some tests as appropriate, and if he is willing, I will recruit him into the organization.”

Chapter 43 The Snake and Eagle Duo

On Saturday morning, Su Yu and Lupin met with Gemma Farley's parents at their shop in Hogsmeade Village and discussed the cooperation with them.

The initial plan is that the Farley family can receive 100 magic phones from Su Yu every month.

Each unit costs 40 Galleons, on the condition that they cannot be sold within the UK. As for where they are sold or how much they are sold for, Su Yu has no say in that.

The Farley family was very satisfied with this offer. Firstly, the item was planned to sell for 50 Galleons in England, and even if they sold it for the same price, they could still earn 1 Galleons a month.

Secondly, since the product has been exported, the price will definitely not be the original price. Given the product's excellent performance, it will surely be a hit and in short supply. It would be perfectly reasonable for me to add a little more money to sell it.

Finally, their directly operated stores in four European countries have never had their own unique products, resulting in a lack of competitiveness. With this magic phone, the increased traffic can boost sales of other products and enhance their brand awareness, achieving multiple benefits at once.

The two sides quickly reached an agreement. Upon learning that Su Yu wanted to take their daughter as his disciple, the Farleys were even happier and presented Su Yu with a Farley family medal as a symbol of their friendship.

According to them, this medal can be used at any Farri family shop to withdraw 1000 Galleons, and also grants a permanent 15% discount on purchases made at that shop.

After seeing off the Farley family, all the preparations for the sale of the magic phone were complete, and Su Yu finally breathed a sigh of relief. He had been incredibly busy these past few days.

For the past decade, these matters have been left to the Stuart family to worry about. Suddenly, all of them have fallen on my shoulders, which is quite tiring.

So that afternoon, Su Yu put aside all his work and research, hugged a lump of coal, and strolled around the Black Lake with Tonks, reliving his student days.

Tonks told Su Yu a lot about the funny things that happened when he was in school because he couldn't control his abilities.

"Tell me about yourself. What fun things happened when you were in school? Did you date anyone?" Tonks asked curiously.

Su Yu immediately shook his head like a rattle: "No, at that time I thought that being in a relationship would only affect my speed of learning magic."

"So I spend almost all my time studying alchemy every day."

Tonks wrinkled his nose and asked, "Won't that be boring?"

"No, studying alchemical runes is a very interesting thing; they have countless permutations and combinations."

Just as Su Yu was about to begin explaining the wonders of alchemy, he saw Tonks's resistant expression and had no choice but to change the subject, saying, "But I also have a very good friend, Snape."

"Good friends? Are you kidding me? I really can't imagine how I could be good friends with Professor Snape. When I was in school, I couldn't even look him in the eye." Tonks shrank back, saying with some lingering fear.

"Because we had a common enemy, and Snape was quite adorable back then; he called himself the Half-Blood Prince..."

As they chatted, they sat down on a large rock by the Black Lake. Tonks' magic was sealed, and Su Yu, worried that she would get cold, put up a thermal shield.

But perhaps because it was too warm inside the thermal insulation shield, or perhaps because it was too comfortable, after a while, Tonks actually fell asleep with his head on Su Yu's lap.

There was a large lake in front of them, a beautiful girl beside them, and a playful kitten around them; everything seemed peaceful and beautiful.

Su Yu took out a wizard's robe and draped it over Tonks. He then reached for a book to read, when he suddenly saw the diary he had obtained from Timo.

When Su Yu read it before, he felt that there was something wrong with this diary. The legend about the jumping pot and the secret realm that could erase people's memories were all a bit strange.

However, the timing wasn't ideal when he was in front of Teemo, so Su Yu didn't get a good look. Now that he has nothing else to do, he can take a closer look.

This time, Su Yu chose to carefully read through the diary from beginning to end. The diary begins with the story of a cane maker named Little Anthony who accidentally obtained a strange book called "The Tales of Beedle the Bard" in Knockturn Alley.

This children's book is famous in Britain and even in the entire magical world, but the one Anthony got was different. First of all, it was made of human skin and was covered with magic.

Anthony guessed that it was most likely made from a wizard's skin, and the contents of the book were also strange, containing only one story, "The Jumping Pot".

The version of the story was also different from the one in the usual Beedle's Tales. Out of curiosity, Anthony bought the book.

Back at the wand shop, Anthony tried many methods to see if there were any secrets in the book, but he found nothing.

Just after he had given up for a long time, by accident, the book fell into the magic wand's elixir and a map appeared inside. The final point on the map was a bouncy pot.

So Anthony invited a few of his friends and embarked on an adventure together. Su Yu had read the rest of the story, which meant that the key to the problem should lie in that special book, "The Tales of Beedle the Bard".

Recalling the situation in Anthony's basement last time, he searched almost everywhere but did not find anything resembling a human skin book. Could it be in this diary?

Su Yu drew his wand and read aloud into the notebook: "Reveal yourself immediately!"

With Su Yu now at LV8 magic control, the tip of his staff spewed out thousands of silver threads, thinner than a hair, enveloping the entire notebook and quickly revealing its secret.

It turns out that there was a narrow gap on the side of the cover of this diary, and a seamless stretching spell was cast on this gap, which contained the book "The Tales of Beedle the Bard".

Taking the book out, Su Yu didn't rush to read it. Instead, he used his magical tools to examine it. There were indeed faint magical patterns on the cover and the paper, and magic power was flowing within them.

Judging from the magic rune circuit, this thing should be harmless to humans. It's more like a kind of proof. It wasn't written in the notes, but Su Yu guessed that it might be the key to opening the secret realm.

In addition, there is another type of hidden rune, which should be the map hidden within the notebook.

After confirming that there were no problems, Su Yu began to read the book. According to the version widely circulated in the wizarding world, the story of "The Bouncing Pot" is about a wizard who owns a bouncing pot that can brew his own potions.

The wizard used it to help the people in the town, to heal their injuries and illnesses, and to dispel their troubles. But when the wizard died of old age, his son was unwilling to help others.

When someone seeks help from this wizard's son, he always refuses, so the Jumping Pot transfers the suffering of the person seeking help onto the wizard's son.

In the end, the wizard's son had no choice but to follow in his father's footsteps, helping people in the town and becoming a respected figure.
