Harry had heard it in a fog, but he knew one thing, that the Ministry of Magic would not be warned if he could do magic in Charon's house.

Skipping the episode, Charon continued, "Harry, that's nothing, what you're looking for is my latest masterpiece." Look, this is the magical world I built, Charon Labs! ”

Harry looked confused as he followed Charon through the small portal, and a new world was in front of him. This is a hall of more than 100 square meters, most of which is empty, only a few tables are placed in the center, and some messy equipment and instruments are placed.

"How's it going, spectacular?" Charon raised his hands and spun in a circle, asking triumphantly.

"Very good," Harry was indeed surprised that Charon could make such a big place here, "It's quite big and spacious!" ”

Caron saw that Harry had thought for a long time before he spit out these two words, and then looked at the hall objectively, as if there was really nothing worth mentioning except for spaciousness, he smiled wryly: "Harry, you can't just see that there is not much here at the moment, you have to see a grand future." Imagine that you build a magic laboratory of this level in your own home, and you read books in what seems to be a room every day, but in fact you are conducting great scientific experiments here, isn't it cool?! Besides, the construction of the laboratory can't be put in place all at once, and slowly everything will happen. ”

Harry slowly came to his senses, and after thinking about all this, he couldn't help but admire Charon. He actually built a comfortable and free world for himself quietly under the noses of his parents, and this ability and financial resources were unimaginable to Harry.

He looked at Charon, and words of admiration and excitement began to gush out, "Charon, you are too powerful, too amazing." I'm sure anyone in the class would be speechless with envy and jealousy when they knew about it. You must have spent a lot of time, a lot of energy and a lot of money on such a big project! ”

The late compliment from his friend made Charon flutter, this was the right way to open it, and Harry was just shocked and didn't react for a while. Charon began to gush on how he had brought the parts in and put them on and on and on.

However, when it came to the cost, Charon immediately hung his head, "This lab has spent all the money I have saved, and just buying the materials to solidify the space folding spell has made me almost bankrupt. Now I'm a pauper. I had to make a lot of money to get the lab up and down. Okay, let's talk about these things another day, it's getting late, you should hurry up and rest! ”

The two said goodnight to each other, and Harry was furious, frightened, and overjoyed, and was already exhausted, and soon fell into a deep sleep as soon as he lay down on the comfortable bed.

The next day, Charon dragged Harry along with him to get his new invention.

The inspiration for this new invention came from the magic journal. Charon told Harry about the invention.

"Harry, what do you think is the most important thing to care about as a young wizard?"

"Yes, you're right, the most important thing is to learn. From the first to the seventh grade, we had a myriad of knowledge to pour into our heads, and not everyone could be like Hermione, who had a great memory, memorized everything, and became a jack-of-all-trades. ”

"Those ordinary little wizards, every time they want to look up a point of knowledge, they have to remember which book he is in, and then go to find that book, and flip through the thick book little by little. That's why libraries are always overcrowded. Do you understand what I'm talking about? ”

Harry was a good listener, and he sat back in the comfortable sofa chair in the lab, listening to Charon's tirade without saying a word. Seeing him ask, he quickly nodded, indicating that he understood.

"Well, if there is something that is like a small diary, it can be easily stuffed into a bag and taken out anytime, anywhere. If you want to check any knowledge, as long as you enter it on it, all the knowledge points and related information will come out. You don't have to search for it, you don't have to look through a book, all this knowledge is in front of you. What do you think of this idea? I call it a jack-of-all-trades magic diary! ”

Harry roughly understood, and he met Charon's eager gaze, pondered for a moment, and asked, "You mean that this diary contains the knowledge of the entire library?" As long as you type and search in the diary, all the relevant knowledge points will be displayed, right? ”

Charon nodded hurriedly, correcting some minor deviations in Harry's understanding, "It's not the knowledge of the entire library, that's too much, but some little wizards can use the knowledge they want." And we don't have to record everything. ”

"My idea is to pack the knowledge points by grade. First-year students should learn the knowledge pack, and second-year students should learn the knowledge pack...... And so on, we can also package it according to the course, what spell class is all-inclusive, magical creatures all-inclusive...... and even some specific packages according to needs, such as love knowledge package, field investigation knowledge package and so on. ”

Harry was a little confused, "I don't understand, what kind of knowledge pack is in the magic diary we sell?" ”

"Hehe, you don't understand." Charon smiled inscrutablely, "The magic diary isn't important, it's the knowledge package inside. We will sell the diary at cost in the future, and the money we make is the money of the knowledge pack! For example, a first-year freshman can only buy the standard version plus the first-year magic knowledge pack. But when he gets to the second grade, he will have to buy the second grade should know magic pack, which is not free. If he didn't buy it, then the magic diary would be useless, so he would definitely buy it. ”

"Oh! I understand. Harry finally figured out Charon's thoughts, this guy is a profiteer, first using a cost-priced magic diary to attract customers, and then making a fortune with a knowledge package at almost no cost.

Charon was smug, he had learned this idea from Muggle sales books, wizards were rigid in their minds, and they knew that the thinking and philosophy of the Muggle world could crush them at will.

Of course, although the idea is good, you still need to make a physical object of the magic diary as soon as possible, so that it is not a pipe dream.

Charon's design for the magical diary was originally inspired entirely by the memories of Voldemort's remnant, who he learned from Salazar Slytherin's dark magic heritage. The entire production method is copied exactly, without a trace of improvement.

This method of making is nothing more than a dark magic soul dwelling artifact, except for handwriting input and paper display, all knowledge storage and search originate from the memory of Voldemort's remnant soul, and when the remnant soul is gone, this diary is useless.

Charon naturally couldn't copy it like this, if every diary had to add a person's soul to it, he would be even darker than Voldemort. Of course, he wouldn't be stupid enough to cut out a slice of his soul, his mind was still normal.

The question arises, what kind of methods are used to store and search knowledge?

First of all, the method of implanting souls must be ruled out, not only because it is strictly forbidden by the Ministry of Magic, but even the Shafiq family cannot disobey it in a grand manner. Second, the practice itself is cruel and dangerous. It is absolutely inhumane for the souls of intelligent beings to be put into magic weapons, and it is also a matter that will definitely go to Azkaban Prison. If it is a non-intelligent creature, then the wisdom of the soul is far from enough.

Voldemort's legacy of the dark arts has no solution to this. Originally, the reason why it is called black magic is because this kind of magic is known for playing with the soul, and if the soul part is excluded, the black magic is basically abolished.

Charon decided to look for another way.

With Harry's help, it was much easier.

In the Shafiq family's library, Charon and Harry squatted in it for a week, flipping through countless books, and finally came to a harvest.

It was the first time Harry had seen such a large private library, no smaller than the Hogwarts House library, and it was full of necromancy-related content.

It was also the first time in his life that Harry had seen so much of the dark arts, and those Shafiq ancestors hundreds of years ago were unscrupulous dark wizards, who captured intelligent creatures and even other wizards at random for experiments, and all kinds of methods could not be called cruel. In their eyes, these creatures or wizards are just materials, just like a chef treats chickens, ducks, and fish, and how to handle these materials with a smart way is what they care about.

Harry finally understood why everyone in the wizarding world was so afraid of the Shafiq family! What is Voldemort compared to them? What kind of life-requisitioning spell kills people in an instant, it is simply great mercy!

Harry read these books and felt bad all over his body!!

Charon finally found out about this and hurriedly comforted him: "I'm sorry, Harry, for exposing you to so much dark magic content. In fact, black magic is also the crystallization of the wisdom of previous wizards. Just like the medicine of the Muggle world, those ancestors also stole corpses and used slaves for experiments, and only accumulated little by little, until modern medicine was developed. It is true that our ancestors had many problems, but as the younger generations, we should base ourselves on ourselves and study the contents critically. Be firm in your heart, not be fooled by these dark magics, and only sift through what little content is available. ”

Harry pondered for a moment and nodded, "You're right, I understand how I do it. ”
