Harry Potter’s Book of Sin

"Found it!" Maca couldn't help but feel happy to find the information he wanted quickly.

He looked at the contents of the book line by line, and read silently in his mind: "Fairies, magic part level: XX, the fairies hold a wand like a branch in their hands..."

At noon that day, Maca couldn't wait to open one of the books he had ordered, the Potions Book called "The Book of Potions."This is an ancient book published in the 16th century. If he hadn't seen it on a list of used books in Lihen Bookstore, he would have missed it.

In this potion book, Maca saw a very interesting material-fairy wings.

This is a very rare potion material. Although fairies will not die because they lose their wings, they are never willing to let people take their wings away.

"... Fairies' wings have unique magical properties. They can make the fairies shine when they need to show off, and they can also hide their whereabouts when they need to hide."

"If this kind of wings can be used as the main material for blending, perhaps a very special stealth potion can be formulated." Maca couldn't help but guess.

How to make a person invisible is a very attractive question.Except for the invisibility cloak with complex craftsmanship and the phantasmagoria with high difficulty, only a few potions can achieve the effect of allowing an adult wizard to hide his figure relatively perfectly.And these magic potions, without exception, are very expensive-some of their ingredients are quite hard to find.

This gave Maca the idea of ​​"Why not research a new invisibility potion by myself", which seems a little unrealistic.

Although Maca himself knew that he might not be sure, he saw this as an opportunity to challenge himself.

Opportunities are created by yourself-Maca has always thought so.

"Excuse me, do you know where the books on'how to cultivate valerian' are placed." Just as Maca was about to put the book in his hand back on the shelf, he suddenly heard a slight voice from behind.

Because the voice was too soft, Maca could not help but have the illusion of "maybe he heard it wrong".In order to confirm this idea, he went back to confirm it.

"Uh, what did you just say?"

Behind Maca, a girl who was tightly covered in a wide Slytherin robe stood quietly in front of her.On her head, she also wore a wide-brimmed pointed hat, covering more than half of her face, and Maca could only see a pair of pink lips.

"Excuse me, do you know where the books on'How to Cultivate Valerian' are placed?"

The petite girl repeated what she had just said verbatim, and her unchanging tone reminded Maca of Professor Bins who taught the history of magic.

"Uh, um, the herbal medicine books should be over there." Maca subconsciously pointed to the book shelf area not far from here.

As soon as the words fell, the mysterious girl in Slytherin immediately turned around and walked over there, without leaving even a "thank you".

"What's the situation?" Maca stared at the girl's back blankly, feeling ignored.

It seems that in the eyes of that girl, Maca is just like a tree on the side of the road, and it does not need to be noticed.

He tilted his head and thought for a moment, at least in his memory, he did not find the existence of this mysterious Slytherin girl.

"Well, forget it, I'll know if I have a chance to ask, it seems that it should be a freshman in this class, right?" Maca shook his head, and then walked to the potions library.

Maybe he will come to the library frequently in the future. He found that the amount of books here is really amazing. If you search carefully, you will definitely get a lot of gains.

In the next few days,

Most of the time, students who come to the library can see such a scene——

Near the long reading table near the potions and herbalism bookshelf, there is a place that is always overwhelmed by a large number of books.Those books are large or small, thin or thick, but most of them are theoretical books that are borrowed only by senior grades and even teachers.

And Mrs. Pins, the librarian, usually stared at this position not far away, as if the person sitting there was trying to assault her child, with sharp and angry eyes.

If you want to figure out who is sitting there, you have to go around to see clearly, because the front is completely blocked by the book.

Inadvertently, Maca has become a topical figure among Hogwarts students.

This was not only because of his eye-catching behavior in the library, but also because he was the only non-Slytherin student who could have a few words with Snape and was not ridiculed.

Regarding this point, even the Master Master who has an excellent grade in the potions class can't do it.

"That's just because Hermione is a Gryffindor." When Ernie told Maca about the rumor, Maca shook his head and replied.

As a student, Miss Granger is undoubtedly quite excellent, and Maca also has to affirm the tremendous effort she has put into it.But again, he doesn't think this kind of unrejected learning method is a suitable choice, especially when you are a wizard.

During this period of time, the more deeply he studied, the more sure he was of this-magic knowledge is too broad and profound.In-depth research on the subject of potions alone may consume his entire life.

...

When a person is immersed in something, time passes very quickly.Unconsciously, a week passed in a hurry.

During this period of time, Maca did not meet the mysterious Slytherin girl again, but his understanding of potions has been advancing all the way.

Regarding the potions books he ordered, Maca has already fully understood, and he has made many major breakthroughs regarding the "new invisibility potions".

Regarding the study of "how fairy wings achieve the concealment effect", Maca has come to a conclusion.This is a new type of "optical invisibility" that is different from invisibility cloaks and phantom spells, and a new type of "environmental invisibility" with several ancient potion formulas-"perception blocking invisibility".

This is undoubtedly a very effective means of invisibility. Although you have not changed objectively, others cannot "feel" your existence.

"But this thing is really expensive!" Maca lay weakly on the table and sighed heavily.

In his calculations, he found that if a wizard is to completely conceal his existence, the amount of wings in the formula must reach a very high value.

"'Fairy's Wings' one portion is 8 gallons, and three servings is 24 gallons; plus other ingredients and catalysts, the cost of a bottle of finished product will be 43 gallons..." Counting here, Maca He sighed again, "It's a robbery!"

"...Wait! Why do I have to worry about this!" Suddenly, Maca stood up suddenly as if he had discovered a new world.

"No noise in the library!" Mrs. Pins shouted hysterically.

"...She doesn't care if she is noisy or not." Not far away, a few Ravenclaw girls were whispering.

Maca apologized to Mrs. Pins with embarrassment, and then sat back in the pile of books.

Without a doubt, what does a new potion with practical effects mean?This means wealth!

Compared to the rarity and expensiveness of the few invisibility potions currently available, Maca's potion is already cheap enough.In the entire magic world, the price of rare potions has always been high. Potions masters like Snape who have created and improved several precious potion formulas with significant effects are even more sought-after.

Had it not been for Snape who involved too many stories, and if he were not interested in this, he would have served as an exclusive consultant in a potion maker or a nobleman's house.

What do you have without money?Since ancient times, which potion master is really short of money?As long as the sales channels are carefully selected, it is more than enough for Jin Jialong not to say that he is coming, but to support him to continue research.Speaking of trading, this is what Maca is best at.

Early the next morning, he asked Marfa to send him a shopping list, and he wanted to immediately start to make this potion.Before that, there are several problems that will be encountered in actual preparation, which must be solved first.

"Tuk Tuk Tuk"

During the lunch break, Maca knocked on the door of the office of Professor Snape's Potions Course, which almost no one would actively knock.

"Who?" It was still that gloomy and indifferent tone, making visitors feel that they were not welcomed by the host here.

"Professor Snape, it's me, Maca McLean."

"...Come in." The voice inside paused before answering.

Maca turned the doorknob to open the gloomy dark room, and then walked in quickly.

"Professor Snape, I have a few questions about potions. I hope I didn't interrupt you." Maca said carefully, making himself as polite as possible.

Snape glanced at him blankly, then said with a hint of impatience: "Ask."

"In fact, I encountered a few questions in the process of studying potions books. For example, regarding Hirst's second law, how to deal with the maniac reaction that occurs in the actual preparation process, so that the original liquid medicine Continue to maintain a stable magic power form?" Maca nodded, and then quickly asked the question.

"Humph." Snape frowned and snorted coldly.
