Dynavale and Hogwarts

When Dana walked into the library again, he thought that he hadn't been here for a week.

This time, Dana came here mainly to start studying the magic paintings. I've wanted to buy it for a long time, but I just didn't get around to it until now.

Dana walked to the last bookshelf, took down the seven or eight books on magic paintings, moved them to a secluded corner, put on gloves, read them carefully, and kept writing down the key points.

Dana had always thought that the principle of magic paintings was the same as those of the photos in the Daily Prophet, a bit like a short video of the Muggle world, all realized through the principle of persistence of vision of the eyes.

But now I understand that the principle of magic painting is completely different. Whether the things in the magic painting will move or not depends entirely on whether the artist used magic to preset the behavior pattern of the thing when painting.

It's the same principle as transfiguration to create a demonic creature.

The things in the magic paintings, such as human portraits, can partially interact with the real world because the space in which the portraits are located is not a two-dimensional space, but a sandwich space between the two-dimensional space of the canvas and the three-dimensional space of reality.

Therefore, the portrait has the characteristics of two-dimensional space: it still exists on the canvas and cannot make substantial contact with the real world; it also has the characteristics of three-dimensional space: it can move and interact with real-world information.

According to how to successfully make a magic painting and other books, at the beginning of making a magic painting, you need to use alchemical methods to open up a mezzanine space, use alchemical potions to draw an alchemical array on the canvas, and then activate the alchemical array through magic power.

Now the knowledge related to alchemy arrays and alchemy potions is monopolized by three families, and the specific array diagrams and formulas are strictly kept confidential. To paint a magic painting, you need to purchase processed canvas from these three families.

In the book Magic Painting from Beginner to Master, the mail order address of the supplier is listed. Dana admired the author of this book very much. He could make a fortune from the copyright, and he could also make a fortune from advertising fees. I'm jealous

In addition, the depth of field of pictures in the Muggle world is achieved by arranging the size of the scenery according to its distance from the observer.

This is not the case with magic paintings, where the scenery is layered on top of each other.

First apply a special alchemy potion to expand a layer of space on the mezzanine space, then draw the scenery farthest from the observer, apply another layer, and then draw the next farther scenery until all the pictures are completed.

From the perspective of an observer in a three-dimensional space, as more layers of space are superimposed on it, the scenery on the layer will become smaller, which is in line with the habit of viewing paintings.

But for the people in the painting who are also in the same mezzanine space, the scenery is still the original size.

Just like the magic painting in the Dana family inheritance room. As the old man walked deeper into the picture, Dana saw the old man getting smaller and smaller.

But from the perspective of the old man in the painting, there is no change in the size of himself or the scenery, but the layer of space he is in is getting further and further away from Dana.

Dana checked and found that the formula of this alchemical potion was also confidential, and the finished product needed to be purchased directly.

Dana thought that if there was no background and it was just a portrait, there would be no need to expand the extra layer of space, so it would be fine not to use this alchemical potion. No wonder most of the portraits we see are just portraits without background.

Everything that is monopolized will not be cheap.

However, Dana did not have to paint the portrait himself. As long as these portraits can form a communication network, Dana only needs to persuade a magic painting to be the source of spreading news. It doesn't matter whether he paints it or not.

Unfortunately, judging from what Dana learned, it seems that this is not possible yet. For example, the Fat Lady can only visit nearby paintings; she cannot run into a painting at the Weasley house.

Unless the Weasleys also had a painting of the Fat Lady so the two could easily meet. So the current situation is that they are either close or have the same origin.

Dana's understanding is that the characters in the painting can instantly move from one mezzanine space to another. The premise of this is that the road is close, so you know the path, and you will not go to the wrong mezzanine space; if you are from the same source, you still know the path, and you will not go to the wrong mezzanine space based on induction.

As long as the person in the painting knows the path, in theory, mutual visits between any two paintings can be achieved, no matter how far apart the paintings are.

Dana felt that the secret of the magic painting was more than that. For the portrait in his family's inheritance house, the entire painting was burned with a torch. This shows that under certain conditions, the things in the painting can make substantial interference in the real world.

It made sense for the family to burn the painting. This kind of technology is not a common product, and there may be many technical details that I have not discovered.

Dana shook his head to get the thought out of his head. Ever since he came to the magical world, Dana had never thought about finding his family. There is nothing better than being able to forget each other in the world.

Before dinner, Dana finished browsing these seven or eight books. When I put the book back on the shelf, I saw that there were more than ten books about magic paintings on the shelf. I couldn't help but shake my head. There were so many more.

While putting away the books, Dana discovered a notebook. Dana flipped through it curiously and found that it was a deduction of the two alchemical potions used in the magic painting.

Dana felt that the logic of the deduction was quite rigorous, so he became curious and planned to borrow it back to take a closer look.

After finishing the borrowing procedures at Mrs. Pince's place and about to leave, Mrs. Pince stopped Dana.

"Are you interested in magic paintings?" Mrs. Pince asked in a low voice.

"I want to see if the process of casting a spell can be made into a magic painting to facilitate learning." Dana whispered the excuse he had thought of for a long time.

"Photos only have images and no sound; magic paintings have images and sounds, but the things in the magic paintings cannot spell or cast magic." Mrs. Pince said quickly, and continued to explain:

"The canvas and alchemy potions needed to draw magic paintings are controlled products. Only magic painters registered with the Ministry of Magic can purchase them. There is a limit on the number of registered magic painters. As far as I know, the number of magic painters is currently full, and there will be no Registration is open.”

Dana felt that his previous deliberate attitude of caring for books was richly rewarded. If it weren't for Mrs. Pince, it might have been a long time before Dana could collect this information.

Dana thanked Mrs. Pince for the reminder and left the library.

On the way to the restaurant, I couldn't help but think: It seems that we can't treat everyone else as fools. The public opinion function of magic paintings has long been discovered and restricted by the Ministry of Magic.

On the contrary, he underestimated everyone in the world.

What should I do next? Find a magic painting and convince it to cooperate with me in doing experiments.

It shouldn't be difficult to convince it to deliver the message, but cooperating with the experiment sounds unreliable, but when other ways are unavailable, it can only be tried.

Dana returned to the common room and saw a bunch of first-year students playing a three-dimensional version of Monopoly. It is said to be the latest product of the Weasley brothers, and it also comes with a lot of trick props for use in the game.

A feedback form is also included. When you fill it out carefully and return it to the Weasley brothers, you will receive some additional prank props. Dana felt that the Weasley brothers really had a talent for business.

Dana saw that the little man representing Wolfgang took four steps according to the dice, and it said "Attacked by Thunderbolt Eggs", so the others threw thunderbolt eggs at Wolfgang.

There was a burst of lightning and thunder, and then Wolfgang's face turned darker and his gray hair stood up, as if he had just been struck by lightning. Seeing this scene, everyone including Wolfgang laughed non-stop.

Thanks to the Weasley brothers, it looks like the Monopoly game will remain popular for a while. The brothers should be able to make a small fortune.
