A magical journey that begins in Azkaban

Rogge thought that if he sold Professor Lupine's telescopic magic thread to Delis, he would definitely make a lot of money. So after class, he took the initiative to stay and prepared to chat with the professor.

After all, there is intellectual property protection in the magical world, but he is still unwilling to plagiarize directly. Especially when looking at Lupine's old, wrinkled robe, one feels sympathy.

Rogge was deliberately sorting out the airship design drawings slowly, but his eyes kept wandering between Lupine and Harry. Harry seemed to be having nightmares again recently, falling into dark, weird and strange places from time to time.

Although Lupine is not Harry's godfather, as Harry's father's most loyal friend, he completely regards Harry as his biological son. Especially when it comes to taking care of people, he is more delicate and warm than Sirius.

He listened carefully to Harry's words, his expression gradually becoming serious. When he was about to talk about the secret room in the Ministry of Magic, Harry suddenly stopped talking and turned back to stare at Roger who remained motionless.

"Travis, aren't you leaving?" Harry's voice contained an obvious warning, and his tone was quite forceful, trying to expel Roger from the classroom.

Rogge closed the folder and played with the telescopic magic thread leisurely: "Professor Luping, I have some ideas about magic threads that I would like to discuss with you."

"You want to cheat?" Before Harry could finish his words, Lupine resolved the awkward atmosphere with a smile and softly invited, "Come to my room to talk."

His lounge is just behind the Defense Against the Dark Arts classroom. The layout inside is too simple and plain to the point of lack of brilliance. The broken suitcase on the cabinet was very conspicuous, especially the tag with Lupin's name on it, swaying gently in the wind.

Rogge sat on a wooden chair. He glanced around the room and asked curiously: "Professor, you have been teaching at Hogwarts for more than two years. Haven't you added some new items?"

He paused and then said: "If your salary is a little tight, the Travis family is willing to donate a fund to the school board specifically to increase the salary of Hogwarts teachers."

Harry was angry at Roger's arrogant attitude, and his nostrils dilated as if he were about to spit out fire. His right foot stomped heavily on the ground, muttering dissatisfiedly: "Don't think that being rich is a big deal!"

"Sorry, Harry, being rich is really amazing, haha." Rogge smiled softly, his words revealing a sense of confidence but not being impolite.

"Ahem..." Lupine cleared his throat unnaturally. Although Rogge was the son of the school director, he still felt the need to remind him: "Rogge, Garen is not omnipotent."

"Of course, Professor." Rogge humbly accepted Lupin's reminder and said with concern: "But you are a professor at Hogwarts. You should have the dignity of a professor and enjoy a quality life. This is also the responsibility of the school board. My mother is willing to Donate generously for this..."

Lupine quickly raised his hand to stop Rogge from continuing. There was a hint of determination in his eyes, but also a gentle smile. "The salary of a professor is already very considerable, and I am very satisfied."

"I choose to be frugal because I believe there are more important things in life than material things. This is more important than decent clothes, furniture or accessories."

Rogge nodded slightly and asked curiously: "So, you must be supporting some important cause, right?"

Lupine handed them a cup of black tea, smiling but not answering. This silence seemed to be a kind of acquiescence.

Harry thought that the professor had donated the money to the Order of the Phoenix, and praised loudly: "Professor, you must have devoted yourself to a noble cause with a group of noble people." He said, glancing at Roger from the corner of his eye. , seems to imply that Rogge's behavior is not noble.

However, Rogge directly ignored him and played with the magic thread skillfully with his fingertips. "Professor, the Ministry of Magic is looking for equipment that can improve combat effectiveness. I think your telescopic magic thread has great potential and can play an important role in this regard. It can Help the Aurors defeat the Death Eaters."

"If they need it, I can give it to them for free." Lu Ping smiled nonchalantly. He was not interested in the commercial value of the telescopic magic thread. Instead, he valued the ability of the magic thread to improve the Auror's combat power.

Rogge shook his head and said in a firm tone: "You must not do this, professor. You may not know it, but doing so is actually harming people."

"What?" Harry immediately retorted, his eyes full of confusion, expressing strong dissatisfaction with Rogge's statement: "Don't talk nonsense, how can Professor Lupin harm people? Isn't it only harmful to make money?"

Lupine nodded, also not understanding what Rogge said. Could it be that giving it for free would hurt others?

Rogge tasted the black tea calmly and calmly. It tasted silky and mellow, with a slight aftertaste.

It wasn't until he put down the tea cup that he slowly explained: "I respect Professor Lupine's noble character very much. He is willing to give up his own interests for the common interests of the magical world."

"But what about the others?"

"What does it have to do with other people?" Harry was still puzzled, "The magic thread belongs to the professor, not anyone else..."

"That's right, but we can't expect all wizards to have the character of the Professor." Rogge pointed to the core of the problem, "If the wizards in Knockturn Alley were one-tenth kind, they wouldn't do those things. Illegal business."

Rogge looked at Harry with a scrutinizing gaze and asked a hypothetical question: "If you invent a magic item that can improve combat effectiveness, and each item can be sold for 100 galleons, you will be willing to donate it to the Ministry of Magic for free. ?"

Harry beat his chest without hesitation and replied firmly: "Of course!"

His eyes turned to Lupin, the professor's eyes sparkling with pride and satisfaction for him.

"Very good." Rogge nodded and continued to ask: "What if this invention belongs to Ron?"

"He..." Harry couldn't help but hesitate, and he said uncertainly, "He... can also!"

"Oh?" Rogge didn't let go and continued to ask: "Where are George and Fred? Where is Seamus who sleeps with you? Where is Malfoy from Slytherin? And our school is comparable to Gringotts Goblin Where's Theodore?"

He rattled off a list of names, and uncertainty and frustration began to show on Harry's face. He realizes that while he can influence Ron, he can't control other people's decisions.

Not to mention the miser Theodore, even guys like the Weasley twins and Malfoy are unlikely to donate their inventions to the Ministry of Magic for free.

"But..." Harry retorted unwillingly: "But our free provision does not affect them..."

Roger took a deep look at Harry and explained: "If the Ministry of Magic publicly publicizes Professor Lupin's noble behavior, what do you think other people will think? They will choose to donate their works for free like Professor Lupin. , or choose to hide it and sell it to someone with a higher bid? "

Lupine and Harry suddenly understood why Roger didn't offer to give it away for free. If wizards could not get a reasonable reward for their inventions and creations, few would be willing to share their results for free.

Their free gifts will discourage other wizards. After all, who would like to be prostituted for free?

Rogge continued: "Professor, if you can get a deposit from the Ministry of Magic for your telescopic magic thread, then other wizards will get the same treatment."

"This is a war that belongs to all wizards, and everyone can contribute their own strength." His words made Lupine's eyes light up.

At this moment, Rogge finally came to his senses and whispered softly: "If you don't mind, I can help you negotiate this matter with the Ministry of Magic. The funds obtained in this way can also support your ongoing noble cause."

Lupine fell into deep thought, and he seriously considered Rogge's proposal. As long as you make a little sacrifice, everyone can benefit: Aurors can improve their combat effectiveness, and the money they earn can also buy wolfsbane potions to help more children infected with the werewolf virus, and other wizards will also be inspired to make more What a useful prop...

Finally, he made up his mind and decided to do what Rogge suggested. As for negotiations with Ministry of Magic officials, it was troublesome and complicated, so he decided to let the Travis family handle these trivial matters.

Lupine returned to the table, picked up the quill, and began to list in detail the production method and cost of the telescopic magic thread on the parchment.

"The main materials of the stretchable magic thread include dragon heart tendon and unicorn hair, which need to be soaked in moonlight grass juice for a full moon night. Then, add silver wire and weave them into three strands of filament."

"Although these materials look very expensive, because each finished magic thread is only half the thickness of a human hair, the amount of material used is actually very small."

The stretchable magic thread given to the students today was slowly made by Professor Lu Ping using various leftover materials he collected in his daily life. What really gives them value is the magic spell he invented and his unique weaving process.

"Each magic thread contains three spells: tenacity, elongation and shortening." Lupine continued to introduce, and kept writing at the same time, "The original length of the magic thread of 3 inches can be stretched 100 times, reaching 25 feet. It’s almost negligible after shortening.”

"As for the material cost..." Lu Ping stopped writing and scratched his hair in distress, "This is indeed a bit difficult to calculate."

"Dragon heart tendons are leftover materials from the wand shop, and unicorn hair was collected by Hagrid from the Forbidden Forest. Only the cost of silver wire is easier to calculate." He opened the drawer and took out half a Sickle. . "One siko can probably make 32 feet of magic thread."

"That's 10 meters." Rogge nodded, quickly calculating the cost in his mind.

"The dragon farm can provide dragon heart tendon, but unicorn hair is relatively precious and difficult to buy in the magic world. Silver wire is not included, and the material cost is about 10 Galleons."

"So many?" Lu Ping blinked in surprise when he heard this number. He originally felt that the most expensive silver thread was ignored by Rogge.

Rogge responded with a smile: "Professor, this does not include labor costs, that is the bulk of it."

He heard Harry muttering "The black-hearted wizard..." next to him, but he didn't care and continued: "I have two options. The first one is to make your own telescopic magic thread, and then I will recommend it to Ministry of Magic."

"The second option is that I buy the method of making telescopic magic thread for a thousand Galleons. Then, I sell it to the Ministry of Magic at a price of 1 Galleons per foot." Rogge gave a classic dilemma, you Maybe I won’t lose money, but I will definitely make money.

Lu Ping thought for a moment and chose the second option without hesitation. As a member of the Order of the Phoenix, he simply didn't have enough time to mass-produce telescopic magic thread for the Ministry of Magic.

Harry opened his mouth, as if he wanted to say something, but in the end he chose to remain silent when he saw Lupine accepting the Galleons.

After Rogge left, he spoke: "Professor, you are at a loss. One thousand Galleons can only buy one thousand feet. Calculated based on the length of each three inches, that is four thousand telescopic magic threads."

He felt that Rogge was very evil and that Professor Lupin had been taken advantage of. "I heard from Mr. Weasley that there are hundreds of wizards in the Ministry of Magic. If sold to other magical circles, it would definitely be far more than 4,000." The number of magic lines.”

Lupine smiled and filled Harry's teacup again. He said half-jokingly: "Your arithmetic is really good. Maybe you should consider taking an arithmetic class. This way you can get an extra certificate."

What he values ​​​​is not money, but the contribution that the telescopic magic thread can make to the Order of the Phoenix and the magical world. He knew that with this money, he could buy more wolfsbane potions from Snape and save more innocent children infected with the werewolf virus.

Harry shook his head and complained: "I won't go. Professor Trelawney's Divination class is enough for me. You know, the homework she assigned today is to record our dreams for the next two months."

He sighed and continued: "Dreams are only clear when you are asleep. Once you wake up, those details will gradually become blurred or even disappear. Besides, who dreams every day?"

Lu Ting listened quietly, with a flash of sympathy in his eyes. Harry was right, dreams were indeed a fleeting experience, and no one could remember all the details clearly.

Even by the time I got up to drink water, I had forgotten half of last night's dream. After getting dressed, all that was left was a hazy feeling and an indescribable impression.

However, just ten minutes ago, Harry confided in himself the details of the nightmare in detail. He even remembered the portraits on both sides of the passage and the house number at the end of the passage.

Lupine knew in his heart that what Harry experienced was not an ordinary dream, but a real experience that he personally perceived.

Voldemort's body is filled with Harry's blood, and the scar on Harry's forehead contains fragments of Voldemort's soul. Coupled with the disappearance of Harry's Aunt Petunia, the protective spell Lily left for her son became weaker and weaker.

Harry is increasingly able to sense Voldemort's soul, and even sees some of the Dark Lord's secret actions. This worried the members of the Order of the Phoenix, who feared that Voldemort would detect Harry's prying eyes and use this connection to probe Harry's mind.

Therefore, Lupine did not dare to mention these things, lest he alert Voldemort in advance. He could only hope that Snape could teach Harry Occlumency as soon as possible to protect Harry's memory from infringement.

"Professor, Snape asked me to go to the dungeons on Friday night. I didn't make any mistakes, why should I be detained?"

Lupine waved his wand gently, spraying out a stream of water and cleaning the teacups one by one. He replied calmly: "Maybe it's not confinement, but I want to teach you some magic spells."

"Charms?" Harry was even more confused: "Snape didn't tell me at all! And why him? You know, he is prejudiced against me. Can't you and Professor Flitwick teach me?"

"I'm sorry, Harry." Lupine shook his head helplessly, "Snape is extremely good at that curse, and no one in the wizarding world knows it better than him. Even if..."

He paused and originally wanted to say "even Voldemort can't see through", but considering Harry's hostility to Snape, he finally chose to remain silent.

Because he knew that Harry would retort that if Snape could hide it from Voldemort, couldn't he hide it from Dumbledore?

But Lupine knew that even the most complex magic could not compare with a sincere heart. Snape's love for Lily Potter was the source of his loyalty and his strongest belief. This emotion cannot be eroded by any black magic.

However, Lupine and Sirius could not explain these things to Harry. Because their behavior towards Snape was indeed extremely bad. Once they were told, James' image in Harry's heart would be greatly reduced.

Deep in Lupine's heart, he felt a trace of apology for Snape. But when he thought about the price of the Wolfsbane potion that Snape sold, that little apology disappeared with the wind.
