Harry Potter: This senior is pretty strong

After returning from Hagrid's Hut, Qin Yu went to the Great Hall to get some food and then went back to the Gryffindor dormitory area.

He needed to take a shower first; he had spent the day scooping up spider corpses and dispensing the venom, and he smelled terrible.

While showering, he estimated his approximate earnings.

They have a total of 5 pints of S-grade Venom, 3 pints of A-grade Venom, 3 pints of B-grade Venom, and 5 pints of C-grade Venom.

如果按照他们初步的定价，也就是S级1品脱200金加隆，A、B、C级1品脱分别是150、120、100金加隆，那么总收入应该是2310金加隆！

Wow, that's quite a sum!

Even if the four people split it equally, each person can still get more than 500 Galleons.

Then, buying him and Hermione a Nimbus 2000 each would definitely be enough.

Thinking of this, Qin Yu felt a little excited.

However, everything depends on whether Venom is sold.

……

After taking a shower, Qin Yu ate something and began to look through the books he had brought back from Hagrid.

This book is an overview of common magical creatures, roughly equivalent to an abridged version of "Fantastic Beasts and Where to Find Them," making it suitable for beginners. Most importantly, it was written by Newt Scamander, a protagonist-level figure who is quite remarkable. Moreover, only a limited number of copies were printed, making it a rare collector's edition.

Qin Yu skimmed through the pages and quickly scrolled to the end.

Next, he carefully wrapped the book in kraft paper and squeezed it tightly.

After he finished writing the letter, he summoned his owl, Trigg.

Then, Qin Yu handed the package, along with the letter, to the owl, asking him to deliver it to Granger's house in a Muggle neighborhood in London.

As for the content of the letter, it was roughly about encouraging little Hermione to study hard and make progress every day, and mentioning that she had recently had a dream about her, and finally saying that she had received a precious book of magical creatures from Uncle Hagrid, which she could read in her spare time to learn about these magical creatures in advance.

After sending the letter, Qin Yu went to bed. After all, he was still recovering from a serious illness and his energy was not yet fully restored. Moreover, he didn't have a phone to use, so there was nothing to do if he wanted to stay up late.

We can't just chat idly with Elvis, Jimmy, and the others, can we?

Qin Yu felt he didn't have much in common with these kids, so he decided to go to bed early.

……

Because Qin Yu mailed the letter a little late, it was already past nine o'clock at night when the owl knocked on Granger's door.

Hermione was overjoyed to receive Qin Yu's letter so quickly.

She quickly prepared toast and ham to entertain the messenger Trig, who had come from afar. Then, she hid in the house and opened the letters and packages sent by Qin Yu.

This letter was very short, only one page, and not even full. Hermione forgave the guy's "perfunctory" attitude, thinking that she had just received a long letter a couple of days ago. Especially when she saw that he had dreamed about her in the letter, Hermione had no resentment at all. She just wanted to ride Trigg to that magic school right away. It was just a pity that Trigg was too small and not strong enough.

"The letter should arrive quite late, so there's no need to reply that day. Just let Trig stay at home for one night."

Qin Yu wrote this at the end of the letter.

So Hermione decided to put her mind at ease and start reading the book Qin Yu had sent her.

Of course, since it was so late, I could only take a quick look.

Soon enough, her mother urged her to go to sleep, and she placed Trig on her windowsill and put a thin blanket on it so that Trig could sleep more comfortably.

"Goodnight, Trigger!" Hermione said to the owl perched on the windowsill after she crawled into her blankets.

“Auntie~” Trig responded.

Hermione smiled sweetly and closed her eyes.

She hoped she could fall asleep quickly, so that she might dream of Qin.

Qin said in the letter that if you dream about someone, that person will suffer from insomnia.

So, will Qin have trouble sleeping because I dream about him?

As the little girl pondered these unresolved thoughts, she gradually drifted off to sleep.

Whether she actually dreamed about Qin Yu or not, only she knows.

……

Whether Hermione dreamed about Qin Yu or not, Qin Yu was indeed suffering from insomnia.

To be precise, he got up a little early.

He went to bed early last night, but woke up at four o'clock this morning and couldn't fall back asleep.

Then he left the Gryffindor rest area and wandered around the school.

And you know what? Hogwarts was incredibly quiet at that moment, with a unique feeling, as if everything was asleep, waiting to awaken at dawn.

As Qin Yu strolled through the school, it felt as if he were rediscovering the mystique of this magical school.

Unbeknownst to him, Qin Yu had reached the eighth floor of the main building of Hogwarts Castle by stepping on the moving staircases beneath his feet.

"How did I suddenly end up here?" Qin Yu muttered to himself in astonishment.

However, since he was already there, he decided to take a short stroll around, since he had never been to this place before and would treat it as an exploration map.

This place is similar to other parts of Hogwarts, with large corridors and distinctive paintings.

Qin Yu stopped to admire a painting for a moment and greeted the figures in it.

The other person was clearly still half asleep; after lifting their eyelids slightly, they yawned and went back to sleep.

However, just as Qin Yu was about to leave, a wall next to him suddenly changed.

A tall, ancient door gradually emerged from the originally smooth wall.

Upon seeing this, Qin Yu subconsciously rubbed his eyes. After confirming that he wasn't seeing things because he had gotten up too early, he smiled with delight.

Yes, he remembered the system choices and rewards he made before he lost consciousness in the cave of the eight-eyed giant spider.

—The power to summon the House of Requirement!

And this room that suddenly appeared must be the legendary Room of Requirement!

"Sure enough, the early bird catches the worm!" Qin Yu couldn't help but remark, though it wasn't quite appropriate.

Then, he pushed open the door and entered the Room of Requirement.

The Room of Requirement now appears somewhat empty, unlike in the movie where it is filled with many things.

However, Qin Yu thought again that the room was designed to meet the needs of those who entered, and his needs were clearly different from Harry Potter's.

As for why it was an empty room, Qin Yu secretly guessed, "Could it be so I can use it as a storeroom to store things?"

After all, his planned business would require storing a large number of magical creature artifacts, and this place was quite suitable.

Although the appearance of this room was shrouded in mystery, there wasn't much unusual about it at the moment. Qin Yu took a look around, got a general idea of ​​the layout, and then left.

Of course, he will definitely take this place seriously, and it might come in very useful in the future.

……

……

George and Fred, the brothers from Gryffindor, were always the troublemakers and penalizers of their grade, which gave many people a headache, especially Professor Snape. Every time he saw them, he seemed to see the shadow of his old "enemy," and he looked as if he could throw out a "Shadowbreaker" spell to chop off their heads at any moment.

However, recently these two seem to have suddenly changed their ways. Apart from attending classes, eating, and sleeping, they are rarely seen at school. This has made many teachers and students feel uneasy, and many people are speculating that the two brothers may be plotting something big. This speculation is quite popular.

If George and Fred knew what these people were thinking, they probably...wouldn't care.

After all, how could someone who dares to play pranks in various places at school have any shame?

Today, George and Fred did not linger at school either. After breakfast, they hurriedly left Hogwarts Castle.

And the place they were going to was Hagrid's cabin.

“I never knew Uncle Hagrid was so knowledgeable,” George couldn’t help but say to his brother.

“Just like Qin said, ‘When three people walk together, one of them will surely be our teacher,’ and he’s absolutely right,” Fred chimed in.

“This isn’t Qin’s statement. He said it was the words of an Eastern sage. However, it is indeed very true. We should be more humble in the future and learn more from capable people,” George corrected Fred and summarized.

“That’s right. Only by learning humbly can we grow and become people who can shoulder the responsibilities of business!” Fred nodded in agreement.

Instantly, the two brothers felt that their character had been elevated and that they had become people of noble character.

However, a few minutes later, when they saw a small golden unicorn rubbing against Qin Yu's body like a pet dog, they were completely stunned.

"Hagrid, what exactly is going on?"

Why would a proud unicorn do such a thing?

The two brothers asked Hagrid, unsure whether they were heartbroken or envious.

"Oh, Qin came to see me early this morning, and then the little unicorn came out of the Forbidden Forest. After seeing Qin, she became very affectionate with him." Hagrid briefly explained what had happened.

"Why? I don't want Sister Li!"

"I don't like Sister Li either!"

The tone of their voices changed.

"If you want to know the reason, it's probably because Qin saved her when she was in the most danger. She developed a sense of gratitude or dependence on Qin. You know, unicorns are very intelligent creatures," Hagrid tried to explain to the Weasley brothers.

Upon hearing this, George and Fred both sighed. They knew they couldn't do what Hagrid was talking about.

However, they quickly regained their spirits and eagerly moved closer.

“Anna, we are Qin’s good friends, it’s nice to meet you!” George said to the little unicorn.

“Yes, we are Qin’s friends, and you are Qin’s friend too, so we are good friends!” Fred said to the little unicorn.

Seeing the little unicorn's curious expression, George and Fred tentatively reached out their hands.

However, as soon as their hands approached, Anna poked them with her horn in annoyance, clearly not wanting them to touch her.

George and Fred couldn't help but show their disappointment.

However, Anna accepted all the clean radishes they offered.

Tsk, Kelly and Unicorn are truly mother and daughter.

……

"Alright, Anna, you should go back now, or your mother will worry about you," Qin Yu said, patting the little unicorn's head.

Upon hearing this, the little unicorn let out a soft cry, nuzzled Qin Yu with its neck once more, and then reluctantly left the small square near Hagrid's hut and entered the Forbidden Forest.

"She's so beautiful!"

"I can't wait to see her shed her golden color and transform into a snow-white adult unicorn!"

George and Fred remarked.

Qin Yu ignored the two "fangirls" and turned to Hagrid, asking, "Hagrid, has the owl replied?"

After exploring the House of Requirement early in the morning and having breakfast, Qin Yu arrived at Hagrid's Hut. However, as soon as he arrived, he was pestered by an enthusiastic little unicorn to play with him—of course, who could resist the enthusiasm of a golden unicorn the size of a pony?

Qin Yu was lucky he didn't bring the little unicorn back to Gryffindor's dormitory to feed it, but reason told him that the Forbidden Forest was Anna's paradise.

After seeing Anna off, he remembered his important purpose for coming to Hagrid's place: to understand the customer's feedback.

“Yes, almost everyone who received the Venom samples wrote back. I took a look, and they were all quite satisfied with the quality of the Venom, but they all indicated that our price was a bit too high,” Hagrid said.

George and Fred listened attentively to Hagrid's words.

“Since they are satisfied with the product, let’s lower the price by 10%!” Qin Yu said after thinking for a moment.

"Did it drop that much all at once?" George asked, frowning.

“Then we’ll have to sell over two hundred less Galleons overall!” Fred calculated the numbers instantly.

"Huh? More than two hundred?" Hagrid was somewhat surprised by the number.

Hearing what the three of them said, Qin Yu couldn't help but laugh and said, "Who said we're going to sell everything at a 10% discount?"

"So what do you plan to do?" Fred asked curiously.

George and Hagrid also cast inquiring glances their way.

"Hunger marketing!" Qin Yu uttered a term, and before the three could ask any questions, he continued, "Our discounted Venom is available in limited quantities. Each customer has a maximum purchase limit of 10 ounces of all grades of Venom. We won't sell any more!"

"Huh? Why won't you sell it? We have no use for it. Apart from Severus, no one in this school would buy this thing," Hagrid said anxiously.

"I'm just saying we're not selling now! It doesn't mean we won't sell in the future! Remember, a qualified businessman must learn to control the market, not be controlled by it! As for how to control the market, you two can try to think about it." Qin Yu said this last part to George and Fred, but he wouldn't force Uncle Hagrid to do so.

Upon hearing this, the twin brothers both showed thoughtful expressions.

While leaving the two of them to ponder the issue, Qin Yu asked Haig to find paper and pen. He wrote replies to each of the interested customers, offering price reductions and asking them to specify the quantity they wished to purchase so that he could arrange delivery.

"It's quite troublesome..." Hagrid remarked.

"In business, you always have to haggle a bit so that both the buyer and seller can have a satisfactory result," Qin Yu said to Uncle Haige with a smile.

Hagrid nodded thoughtfully upon hearing this, though it was unclear whether he understood the meaning behind Qin Yu's words.

After finishing these tasks, the four of them didn't rest. Instead, at Qin Yu's suggestion, they cleaned, sorted, and categorized the various parts of the eight-eyed giant spiders that Hagrid had dismembered the day before.

These things are all money too; we can't let them pile up in the warehouse and take up space.

Qin Yu planned to bring some along when Haige delivered the goods, and sell as many as he could.
