However, even though Harry was determined, Charon still categorized the books, and those dark magic books that Shafiq's ancestors had no scruples about before the establishment of the Ministry of Magic were read by Charon, and Harry only had to look through the magic books written by Shafiq's ancestors who acted in a restrained manner after the establishment of the Ministry of Magic in modern times.

That way, you don't have to be so embarrassed!

Finally, the two found the right content. This is the content left by a Shafiq ancestor who traveled to the East two hundred years ago.

In the Huaxia cultivation world, it is not very difficult to store words or images on a certain object. The advanced level is like the master's inheritance Yujue, which not only has the master's exercises but also the promotion test, which is both complete and rigorous, and very complicated. The low-level ones are like a photo charm, and they can also record images for a period of time.

None of this was anything to be kept strictly secret, and the ancestor had created magical images that could store extracted materials and be used as reminders of his daily itinerary by combining the wizarding world's method of creating moving images.

His finished product is a portrait of a magical activity, just tell the image all the itinerary, and when the time comes, the image will automatically remind: Mr. XX, your time to participate in the XX meeting is coming, please get ready!

When Charon and Harry saw each other, they were overjoyed, wasn't this what they were going to make!

The two of them copied this part of the book after they had found it, and then returned to Charon's laboratory to start tinkering.

Charon's project doesn't need that kind of voice or image, as long as the search results can be textual. This also significantly reduces costs!

With a precedent, it doesn't have to be so high-end, things are much simpler!

According to this, the problems are solved one by one, and the storage of knowledge is solved first.

Fortunately, this problem is not difficult to solve,

What Charon intended to do was not complicated, he needed to structure the input and assign keywords so that it could be retrieved.

To put it simply, each knowledge point is equivalent to a miniature version of the text image, and then a more advanced management module is used to manage these countless text images, so as to form a whole, that is, a knowledge package. Each journal can support up to 3 knowledge packs. Of course, Charon only plans to leave the factory with a knowledge kit, and if you want to add it, you have to pay for it.

Although it is complicated to make something like this, there are no insurmountable obstacles. Charon pondered for a long time, borrowed from Voldemort's magical diary, blended it with magical images, and mixed it with the content of the Oriental Circular Light Technique, and finally cleverly solved the problem.

It took a week, and now this semi-finished product has come out. Harry waved his quill pen and wrote a long paragraph in his journal. After the words disappeared, Charon swept it with his mental power, and sure enough, the complete content had been entered. Charon then used his mental power to activate this text output, and it went smoothly, and a large section of text appeared in the diary again.

Well, Charon and Harry applauded that the problem of storing knowledge had been solved. Now only the knowledge retrieval function remains.

It's a really difficult question. Whether it is Eastern alchemy or Western alchemy, there is nothing to do.

In Western alchemy, the solution to this problem is very simple, just stuff a soul inside. However, unless the two of them want to go to Azkaban Prison, this black magic weapon should not be done well.

In Eastern Alchemy, the search for knowledge depends entirely on the user's own divine thoughts, which can read things much faster than reading things with their eyes, and they only need to sweep everything to pour into their minds. But the magic diary that Charon was going to make was for ordinary young wizards, who didn't have a mind.

Charon and Harry flipped through the books and materials, but for several days without any progress, the two of them were so exhausted that they almost gave up.

On this day, Harry stumbled upon Charon's computer, which was a high-end thing, and Harry had only seen it, but had never played it himself. The computer was a birthday gift from Charon's 12th birthday father, Aiagos, who was also interested in such high-end gadgets in the Muggle world.

Of course, Charon also has a general understanding of computers, and as a senior otaku two lifetimes ago, his knowledge of computers is far greater than that of all wizards in this world.

Now that he didn't have a clue about making a magic diary anyway, Charon simply turned on the computer and played with Harry. The two played the game for a while and started surfing the web again. Charon skillfully opened the Google page and told Harry that there was all kinds of Muggle knowledge on the Internet, and that just typing it into the search bar would show up countless results.

Harry was obsessed with the magic, and it felt like he had stepped into Diagon Alley for the first time, and a whole new world had opened up before him.

"It's amazing!" Harry exclaimed, "Muggle technology has developed to such an extent that even magic can't do it!" ”

Harry's admiration made Charon's mind seem to have a flash in his mind, and he jumped to his feet, trying to grasp the inspiration, "Harry, what did you just say?" Say it again! ”

"I didn't say anything!" Harry was taken aback, "I just said that I was amazed that Muggle technology is amazing!" ”

"That's right!" Charon suddenly figured it out, and he shouted excitedly, "You're right, Muggle technology is so amazing, the retrieval of knowledge can not be done by Eastern refining tools and Western alchemy, but it can be easily achieved with Muggle technology!" All we need to do is add a handler to the journal, do some programming, and write some search statements! ”

The two said to do it, Charon searched the Internet, and he found that to achieve the basic function of knowledge search, there is no need for the latest technology processor, just use an ordinary single-chip microcomputer, which is cheap and solid, and also comes with memory and input and output interfaces. The program algorithm for text retrieval and keyword scanning is a lot of ready-made, and it only needs to be rewritten.

This really solves the big problem. Charon immediately called and ordered ten tablets for experimentation, this thing is inexpensive, 10 tablets add up to only 200 pounds, which is a small meaning for a local money like Charon who has countless pocket money. It's a pity that the logistics in the UK are quite ink, but the distance of more than ten kilometers will not arrive until the next day.

I couldn't eat hot tofu in a hurry, so Charon had to wait honestly. Of course, while waiting, he also thought about solving the interface problem between the single-chip microcomputer and the magic weapon. The single-chip microcomputer must have input and output electrical signals, but fortunately, there is still a way to convert thunder and lightning in the magic array. It's a little troublesome, but it's not impossible.

Charon did an experiment with all the data, made an all-nighter, and finally got the interface part in order. He was so sleepy that he took a nap and woke up to the end of the day, and Harry had already helped him deliver the microcontroller he had ordered to the lab, and now there was only one last step left.

Harry held his breath as he watched Charon proceed cautiously as he prepared himself. Finally, the hard work paid off, Charon successfully embedded the microcontroller into the magic diary, and the first finished product was finally released.

Charon held the magic journal in both hands, like holding the child born in October, gently placed it on the laboratory table, and then looked up at Harry, his eyes sparkled, and said solemnly: "Harry, I will give you the work of the first magic diary test!" Come on! ”

Harry was also very excited, following Charon in the laboratory for more than half a month, he also went from not knowing anything to now knowing a little bit about it, the more he knew, the more he admired him, looking at this epoch-making product lying quietly in front of him, Harry couldn't help but tremble his hands.

On the other side, Charon took out the experiment notebook in a serious manner, and as he wrote on it, he gave Harry an order.

"Jack-of-all-trades magic diary first test begins!"

"Subject: Harry. Porter. Recorded by: Charon. ”

"Test Content 1: Test Knowledge Input Function."

"Harry, step 1 enter the mana."

Harry nervously held the quill pen and followed Charon's instructions, reaching out a finger and gently touching the crystal on the cover of the diary, and then slowly entering the magic. This is to input energy to the diary, and since the diary requires very little energy, it only needs to be entered by the little wizard himself before using it.

Soon the crystals shimmered, a sign that the magic was full. Harry paused, turned to look at Charon, nodded in satisfaction, wrote down the test after this test, and then began to give the second command.

"Harry, open the first-year spell textbook and enter the method of casting the levitation charm in the journal."

Harry did as he was told, and soon a large section of the spell was copied. Then he stopped and saw a line of words appear at the bottom of the diary: "The input was detected as unentered knowledge, is it stored?" There are two boxes next to it, one with "Yes" and the other with "No".

Harry hurriedly ticked the "yes" box, and then the line disappeared, and another line popped up, "This knowledge has been entered." ”

"Great!" Charon snapped his fingers happily and then wrote a pass at the end of the test.

The next step is to test whether the entered content can be retrieved.

Harry wrote "Retrieval Levitation Charm" in his journal, and then he stopped writing, and the phrase immediately appeared in the tooltip at the bottom of the journal: "A piece of knowledge information has been retrieved." In the center of the journal there was a large piece of text, which was the method of the levitation spell that Harry had just entered.

"Great!" Charon and Harry cheered and jumped, the realization of these two basic functions, marking the success of the magic diary!

The general structure of the Jack-of-all-trades magic diary is complete, and all that remains is a matter of detail. For example, knowledge input must not be copied frantically in every book, which is too tiring. Charon plans to hire some people to enter the knowledge packs one by one, and then use magic to copy the information directly.
