A magical journey that begins in Azkaban

"Harry, why did Hedwig go to Rogge?" Ron asked in confusion as he looked at the white figure passing by in surprise.

For more than a month since school started, Travis has always been the first choice for teachers to ask questions. Whenever there is a strange question, the professors will ask that guy, and then the other person will answer it perfectly to win praise and points.

It happened that the opponent was Slytherin. These outstanding performances made Ron more certain that he would be an evil dark wizard in the future, and even Hermione was considered a traitor to the academy. However, he forgot that Travis never raised his hand during class.

"No, that's not Hedwig." Harry vaguely remembered that the lady he met at the train station also said that her son had a pet snowy owl.

"What's wrong?" Daphne saw Rogge's excited expression and came over curiously.

"The Flash Apparition Potion can be mass-produced!" Rogge said excitedly.

"Really? That's great! So Polaroids can be sold?" After Daphne saw Muggle cameras, she was tired of the bulky and old traditional cameras, and the lengthy film development process gave her a headache.

As early as the beginning of the month, they discovered a silver frost solution with developing effect on Snape's prompt. After half a month of repeated trials and optimizations, a new magic potion was finally made: the Flash Appearance Potion. This dropper is dropped onto a photo and makes the image appear instantly.

So, they collaborated to create double-sided magic photo paper. The outer layer is coated with a black backing film, with a white absorbent layer sandwiched inside. After shooting, the white photo paper will absorb the liquid, causing the image to appear immediately and become a moving magical photo. After the image is stable, peel off the white photo paper, and the remaining black part is the negative for storage.

Rogge always thought that the black negatives were superfluous. The wizard obviously had double copying and enlargement and reduction spells, so why did he need negatives? But Hermione and Elena were adamant: a camera without film has no soul!

Well, Rogge didn't resist, and finally surrendered, promising them that the golem paper would be produced in double layers. But the mass production of the Flash Apparition potion has become a roadblock.

As a key consumable for making money in the future, mass production is completely different from his previous small-scale production in the crucible. It was impossible for Rogge to drop out of school and specialize in refining potions, let alone hand over the formula to other wizards.

After thinking about it, he finally decided to improve the formula. The letter sent by Seiler was Jessica's test result, and the new formula was finally successful. According to this method, from now on, Flash Revealing Potion can be prepared in large quantities and cheaply... to be precise, Flash Revealing Tincture.

"All the problems have been solved!" Rogge said happily, finally having an old antique in his hands to be updated.

"If it hadn't been for the dean's reminder, I never would have thought that the silver frost solution had a visible effect. Thank you also, the Greengrass family for providing a lot of materials." Roger raised the juice to thank Daphne.

"You're too polite...I, I just helped to send the letter back." Daphne lowered her head in embarrassment and clinked glasses with Roger.

"Tell Elena and Hermione the good news quickly. They will definitely be very happy."

Under Rogge's influence, she gradually became able to accept non-pure-blood wizards. Of course, the standards for friends are still very strict. Either have noble blood, or be as smart and outstanding as Hermione.

"If it weren't for the two know-it-all ladies who helped find the information, it would definitely not have been so smooth."

"Yes." Rogge nodded, "But I don't dare call Hermione a know-it-all anymore."

"Tch, who doesn't know it's Qian Qi's nickname?"

Roger smiled, picked up the juice, and walked towards the long table of Ravenclaw and Gryffindor. Through Irina, he also had contact with Irina's father Alexander during this time, and even discussed the situation in the Soviet Ministry of Magic in his letters.

Although the Ministry of Magic of various countries declares that wizards cannot let Muggles know their existence, no one can deny the connection between high-level Muggles and wizards. In fact, Muggles and wizards often influence each other. For example, Hitler's overthrow and Grindelwald's imprisonment, it is difficult to say that there is no relationship between the two.

The harvest in the Financial City before the start of school was nothing more than a small test, and Rogge's real ambition lay in the Ministry of Magic of the Soviet Union. The library there contains a large number of banned books. Roger wanted to do them a favor and liberate the magic book into his study room.

There's no denying that the Hogwarts library is rich in history and well-stocked. But under Dumbledore's nose, Rogge didn't think he could easily learn black magic without being discovered.

"Elena, thank you for your help." Rogge walked to the Ravenclaw table with a smile and handed the letter to her.

"Great, it really worked!" Elena jumped up happily, "You must give me one when the time comes!"

"No problem! You still have a share of the store's profits." Rogge clinked glasses with Elena, "Does your father have any new news about things in Eastern Europe?"

"Dad hasn't replied yet, he just said to wait and see." Elena knew a little about the content of their discussion, and there was a hint of worry on her face.

"It doesn't matter, you can wait." Rogge nodded. When the Kremlin's flag was changed, the Soviet Ministry of Magic would definitely not be at peace. And chaos is the ladder of our progress.

Hermione had never been exposed to Quidditch, so in order to fit in with everyone, she kept reading "The Magic of Quidditch". The little wizards around her complained endlessly. They were tired of hearing the boring rules and prayed in their hearts that she would stop chanting.

"Rogg, the rules of Quidditch are too strange. For example, here, if you catch the Golden Snitch, the game will end immediately." Hermione expressed her dissatisfaction to Rogge and complained: "If someone catches the Golden Snitch at the beginning, wouldn't it? Never lose?"

The people around him breathed a sigh of relief and thanked Roger for coming and ending Hermione's tirade. Even though the other party is the more annoying Slytherin.

"You make sense, Hermione." Roger smiled, couldn't help but look at Harry, and sighed in his heart: "Maybe in a few days, you won't think so."

Harry was keenly aware of the other person's eyes and didn't understand why the other person was looking at him. Every time he saw Roger, Harry would think of the praises his professors had for him: his outstanding talent and his humble attitude. In comparison, except for the title of savior, he is as ordinary as Ron.

"Our Polaroids are ready for sale. You see, my mother has proven that the new method of mass production is completely feasible."

"Really!" Hermione jumped excitedly, "That's great, let me see it quickly?" She couldn't wait to grab the letter and marveled at Roger's ingenious design ideas.

"How did you come up with the idea of ​​using the diminishing purity method for mass production..."

"Shh." Roger motioned to Hermione not to say it, "This is our business secret."

Hermione quickly covered her mouth. The core secret of the Flash Apparition Potion must not be leaked.

"Look, what did I get?" Malfoy emerged from nowhere and snatched the red memory ball from Neville's hand.

"Malfoy, give the ball back to Neville!" Harry and Ron stood up immediately, their angry eyes seeming to eat him alive.

"Mr. Draco, you have really opened my eyes. It turns out that the honor of the Malfoy family is like this." Rogge had a joking smile on his face, and his eyes showed contempt for his despicable behavior.

"Even if your family pursues being obedient to the strong and showing martial virtue to the weak, you are still a member of Slytherin. Please do not tarnish the reputation of our college."

"Travis, our family's honor does not need you to dictate!" Malfoy glared, having long disliked him.

"Neville, as a member of the Longbottom family, you should stand up on your own if something is robbed." Rogge looked at the helpless Neville. If he didn't even have this courage, he deserved to be bullied.

Hermione tried to persuade them, but Percy grabbed her. He also warned his brothers to shut up and that the Weasley family must not get involved in this dispute, even if it seemed to be just a squabble between young wizards.
