A few days later, Harvey had just stepped out of the Mage's Tower when he saw a black cat lying cross-legged in front of the wardrobe and taking a nap, biting a small cylinder in its mouth.

A cylinder tied to its tail indicates that it is unused, and a bite from its mouth indicates that there is a letter.

Hearing the sound of the closet opening, the black cat's ears moved, stood up and stretched out with its forelegs against the ground, came to Harvey's feet and climbed along Harvey's suit to his shoulders and rubbed his face.

"There's finally a reply from the Magic Association." Harvey's right hand reached out to the black cat, and the black cat put the small cylinder it had bitten into Harvey's palm.

Harvey came to the sofa in the living room on the first floor, and the spirit was injected into the information crystal to read the contents of the information crystal, and the black cat jumped on Harvey's lap and lay lazily.

The information crystal recorded the reply of Lotie, the vice president of the Magic Association, first of all, to apologize, because the Magic Association had a lot of things to deal with and replied to Harvey a few days late, and secondly, to give a detailed answer to Harvey's question. At least in the Magic Association of the Kingdom of Baron, there is no record of the relevant spells of [Constructing Enlightenment], if Harvey wants to know about [Constructing Enlightenment], he can go to the headquarters of the Magic Association.

Lottie also gave Harvey some general knowledge about the structure of the Magical Society.

The Magic Association is an academic organization, any country and any race can study in the Magic Association, in order to promote the progress of magic, the Magic Association has set up a system called contribution points, publishing academic papers on magic, creating new magic, cultivating new plants or synthetic beasts, mixing new potions, completing tasks issued by the Magic Association, etc.

Contributions can be used for a variety of purposes in the Magical Society, including buying expensive magical materials, hiring assistants, magical knowledge, or buying a dormitory and research room at the Magical Society's headquarters.

Lottie also found out the contribution points needed to borrow Harvey's construction enlightenment technique, the first-order spell basically only needs a single-digit contribution point, the second-order spell needs a ten-digit contribution point, the third-order spell needs a hundred contribution points, and the [Constructing Enlightenment] requires three hundred and fifty contribution points to check it.

Finally, Harvey's contribution to Nature and Magic is also a contributor, as Nature and Magic is one of the subsidiary journals of Modern Magic, the main academic journal of the Magical Society.

Harvey sat on the sofa and read Lottie's explanation with great interest, the maid Shirley came out of the kitchen with a tray, poured Harvey a cup of hot black tea, put down a plate of cookies, and saw the black cat on Harvey's lap with a curious look, not knowing where Harvey turned this little guy back. The black cat's turquoise pupils stared straight at her, its tail cocked and swaying stiffly from side to side, as if on alert.

"Do you want it too?"

Shirley smiled softly and poured a cup of hot black tea.

After making sure Shirley was gone, the black cat jumped from Harvey's lap to the table, carefully licking one of the cups of black tea and biting on the biscuits.

Harvey picked up the teacup and put it down, thinking about what Lottie explained in the information crystal: "There is still this kind of operation, the principle of "Photographic Crystal" and the production principle paper are about to be written, and it can be regarded as killing two birds with one stone, but I don't know how many contribution points I can get." ”

"It doesn't seem that there is no need to contact the headquarters of the Magic Association, and I am used to the peace of the pond, and I don't know what to expect in the sea."

Erasing the contents of the Info Crystal, Harvey writes a thank you note in the Info Crystal for the Black Cat to take back.

After drinking black tea and resting for more than ten minutes, Harvey returned to the Mage's Tower and plunged into the [Endless Library], the library kept most of the books that recorded modern knowledge, Harvey found all the books related to photographic technology, moved them down and put them aside to pile up into a hill, and then brought a stool to read them in situ.

"There is no room for further improvement in the thesis of the photographic crystal magic array, and I have been studying it for several months when I was shooting the film, and there is no need to continue researching it now. However, there is still room for progress in elaborating the principle of phantoms, especially in the study of the human eye. ”

"Any movie, animation, and game are inseparable from two theories, and I originally thought that it would be okay if these theories were not published, but without substantive arguments, I always felt that my paper was too pale."

"The first theory is the phenomenon of visual retention, that is, the last sight seen by the human eye will stay in the eyes for a very short time, after specific tests about one quarter of a second, when the twenty-four pictures appear within one second, the naked eye will not feel the abnormality, which is why the film has been maintained at twenty-four frames."

"Some games will feel stuttered even at 30 frames, this is because the game screen is temporarily processed by the CPU, and it is impossible to neatly sort the 24 pictures in one second, some pictures take up more than 24 seconds, some pictures take up about 24 seconds, and the uneven arrangement of the pictures can only be filled with more frames."

"The second theory is called the phenomenon of quasi-motion, and the reason why people see that the movie is not really moving is because the movie is moving, because the human brain makes up for the movie picture."

······

More and more books are piled up around Harvey, and there is an information crystal suspended in front of him to record Harvey's dissertation completion, standing on the shoulders of the giant of earth civilization, the dissertation is more like a summary of the earth's culture. This paper is not as crude as most papers, and there is rigorous evidence from the point of view to the argumentation process and conclusion, which meets the requirements of an academic paper on the earth, and it may seem strange in this world.

"The name of the paper... Hmmm... Just "The Function of Photographic Crystals and Their Principles", simple and straightforward. ”

After completing the paper, Harvey went back to the alchemy workshop to produce some tools to demonstrate the argument, such as the magic disk principle.

The paper is divided into two parts, one is to explain the function, production method, principle, magic array, etc. of photographic crystals, and the other is a summary based on modern knowledge.

The next morning, Harvey continued to chant a spell to summon the Magic Society's messenger, the Black Cat, and asked him to bring the information crystal to Dupont Arnold, the president of the Royal Spellcasters Guild.

After doing this, Harvey took out the metal badge he brought back from the Magic Association, about the size of a watch, made of silver-white enchanted metal, with exquisite patterns carved on the surface, and the same spell that could help the caster meditate like the coat of arms of the Royal Spellcasters Association, but rather the badge of the Royal Spellcasters Association was made of imitation of the Magic Association badge.

Consciousness touches the inside of the magic badge and quickly receives feedback.

"Name: Harvey Adrian

Rank: Lower

Factions: None

Contribution points: 10

Special Designation: None. ”

10 contribution points are a reward for joining the Magical Society.

It is impossible to show more information about what Lottie said, and it seems that there will only be a "signal" on the side of the Magical Association. Harvey touched his chin and concluded.
