Harry Potter’s Book of Sin

Found it! Maca couldn't help being happy that he quickly found the information he wanted.

He looked at the contents of the book line by line, and read silently in his heart: Fairy, the classification level of the Ministry of Magic: XX, all the fairies hold a magic wand that looks like a branch...

At noon that day, Maca couldn't wait to open one of the books he ordered, a classic on potion science called Book of Potions. This is an ancient book published in the 16th century. If he hadn't seen it on a list of old books in Lihen Bookstore, he might 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 of losing their wings, they are born with a love of vanity and will never be willing to have their wings taken away.

...a fairy's wings have unique magical properties. They allow the fairy to shine when she needs to show off, and to cover her whereabouts when she needs to hide.

If this kind of wings can be used as the main material to prepare, maybe a very special invisibility potion can be prepared. Maca couldn't help guessing like this.

How to make a person invisible is a fascinating problem. Apart from the complex invisibility cloak and the highly difficult disillusionment spell, there are only a few kinds of potions that can achieve the effect of allowing an adult wizard to hide his body relatively perfectly. And these magic potions are all very expensive without exception - some of their ingredients are quite difficult to find.

This made Maca think why not research a new invisibility potion?, 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 oneself - Maca has always believed so.

Excuse me, do you know where the books about 'How to Cultivate Valerian Root' are placed? Just as Maca was about to put the book back on the shelf, he suddenly heard a slight voice behind him.

Because the sound was too soft, Maca couldn't 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 covered tightly by a wide Slytherin robe stood there quietly. On her head, she also wore a wide-brimmed pointed hat, which covered more than half of her face, and Maca could only see a pair of pink and delicate lips.

Excuse me, do you know where the book about 'how to grow valerian' is kept?

The petite girl repeated what she said just now verbatim, and her tone of voice without ups and downs reminded Maca of Professor Binns who taught History of Magic.

Uh, um, the books on herbal medicine should be over there. Maca subconsciously pointed to the opposite bookshelf area not far from here.

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

What's the situation? Maka stared blankly at the girl's back, feeling like she was being ignored.

It seems that in the eyes of that girl, Maca is just like a tree by the roadside, an existence that 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 enigmatic Slytherin girl.

Well, forget it, I will know if I have a chance to ask, it seems that I should be a freshman of this year, right? Maca shook his head, and then walked to the library area of ​​Potions.

Maybe he will come to the library more often in the future. He found that the amount of books here is really amazing. If he searches carefully, he will definitely gain a lot.

In the next few days,

Apart from shuttling between the classrooms of various subjects step by step with other students, Maca spent most of the rest time in the library on the fifth floor.

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

At the reading table near the Potions and Herbalism bookshelf, there is a spot that is always overwhelmed by a large number of books. Those books may be big or small, thin or thick, but most of them are theoretical books that are only borrowed by senior students and even teachers.

The librarian Mrs. Pince usually stares at this position not far away, as if the person sitting there is trying to rape her child, her eyes are sharp and angry.

If you wanted to figure out who was sitting there, you had to go around to the back to get a good look, because the front was completely blocked by the stack of books.

Inadvertently, Maca has become a talking point among Hogwarts students.

This was not only because of his conspicuous behavior in the library, but also because he was the only non-Slytherin student who could talk to Snape for a while without being ridiculed.

Regarding this point, even Miss Know-It-All, who has excellent grades in Potions, 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 was undoubtedly very good, and Maca had to affirm the great effort she had put into it. But again, he doesn't think this kind of learning method that is open to anyone is a suitable choice, especially when you are a wizard.

During this period of time, the more he studied deeply, the more he was sure of this point - the knowledge of magic was too broad and profound. Just doing in-depth research on the subject of Potions may consume his entire life.

...

When a person is immersed in something, time flies very fast. Before I knew it, a week passed by.

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.

Maca has already fully understood the potion books he ordered, and he has made many major breakthroughs about the new invisibility potion.

Regarding the research on how the fairy's wings achieve the effect of disappearing, Maca has reached a conclusion. This is a new type of optical invisibility that is different from the optical invisibility of invisibility cloak and illusion spell, and the environmental invisibility of 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! Maka lay down on the table weakly, and sighed heavily.

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

A serving of 'Fairy's Wings' is 8 Galleons, and three servings is 24 Galleons; plus other ingredients and catalysts, the cost of a bottle of the finished product will be a full 43 Galleons... 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 is allowed in the library! Mrs. Pince yelled hysterically.

...she doesn't care if she makes noise or not. Not far away, a few Ravenclaw girls were whispering there.

Maca apologized repeatedly to Mrs. Pince with a face of embarrassment, and then sat back on the pile of books.

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

Compared to the rarity and expense of the only few invisibility potions currently available, this potion of Maca is already cheap enough. In the entire wizarding world, the price of rare potions has always remained high. Potion masters like Snape who have created and improved several precious potion formulas with remarkable effects are even more sought-after.

If Snape hadn't been involved in too many stories, so he didn't want to be here, he probably would have been an exclusive consultant to a potion maker or a noble family.

What do you have if you don't have money? Since ancient times, which potion master is really short of money? As long as the sales channels are chosen carefully, it is definitely more than enough for Jin Gallon not to say that he is coming, but to support him to continue his 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 start trying to make this potion immediately. Before that, there are several problems that will be encountered in the actual preparation, which must be solved first.

Tuk Tuk Tuk

During the lunch break, Maca knocked for the first time, the door of Professor Snape's Potions Professor's Office, which almost no one would actively knock on.

Who? The gloomy and indifferent tone was still there, making the visitor feel that he was not welcomed by the owner at all.

Professor Snape, it's me, Maca McClain.

...Come in. The voice inside paused before replying.

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

Professor Snape, I have a few questions about potion science, I hope I didn't disturb you. Maca chose his words carefully, trying to be as polite as possible.

Snape glanced at him expressionlessly, then said with a trace of impatience: Ask.

In fact, I encountered several questions in the process of studying potion books. For example, regarding Hist's second law, how to deal with the reaction of disgusting demons that will occur during the actual preparation process, so that the original medicinal liquid Continue to maintain a stable magical form? Maca nodded, and then quickly asked the question.

Hmph. Snape couldn't help frowning when he heard this.
