In fact, the conditions in this world that can generate infinite communication familiar to Reiner are already complete, not to mention that in the Tower of Rainbow, magic has achieved this, so Reiner naturally doesn't have to worry about hardware issues.

It is the algorithm that he needs to improve.

As we all know, the earth's communication uses radio carrier communication. Simply put, it is the process of modulating the signal to a band that is easy to transmit, then transmitting it from a long distance, and then demodulating the party receiving the signal to obtain the original signal.

According to the Newington-Holland equation system, electromagnetic waves propagate in a straight line, and their speed is equal to the speed of light, and can be reflected with objects such as metal flakes. Then Reiner can easily build his wireless communication network.

At the same time, Reiner introduced a three-way handshake mechanism to ensure the accuracy of the information, and added other detection mechanisms to verify and effectively distinguish signals from different magic computers.

With this, he just needs to work hard on the hardware to create devices that can modem, demodulate, send and receive radio signals, and incorporate them into a magic computer.

These days, Reiner has been devoted to the laboratory and is constantly conducting testing. A week before the end of the winter vacation, Sur returned to Crescent Academy from home. To be honest, after being exposed to magical computers and programming code, Sur truly fell in love with this job. These careers have rekindled her mind to research that has been silent for many years. She felt uncomfortable before seeing magical computers for a day, so she came back early.

In the next week, students came to the school to report one after another. In the new year, students naturally had new expectations. They exchanged their experiences during the New Year, and the one that talked the most was the Crescent Coke theme park.

Many parents of students learned about the existence of this unique amusement park through various channels during the holidays, so they followed their daughter to Prest, took advantage of the end of the holiday to have fun and returned happily.

According to the theme park regulations, students of Crescent College can enter the venue with their own student certificate, that is, the school badge, which also makes these students who like novelties talk and wait to go out for fun on the weekend.

The two most discussed projects were the thrilling roller coaster, and the other was the strange and unpredictable William Castle. According to the information pieced together by the students, the routes and contents in William Castle were not exactly the same. Even with the same route, the strange events encountered were not the same. The students were all guessing what was done. For a time, the number of books on the library about the undead and illusions increased geometrically.

What confused the students even more was another thing that appeared in everyone's dormitory.

This is a black thing, like a box, with a wire connected into the wall. No one knows what it is. It was not until the day before school started that a notice appeared on the public column on the wall of the dormitory public lounge to tell everyone the specific purpose of the black box. At the same time, it was announced that starting from this semester, all students in the grades will add a compulsory but not counted for credits, and learn how to use this equipment called a magic computer.

Seeing this notice, Ashlua and Hathaway suddenly felt a sense of stolen joy. Hathaway, who was able to write code independently, naturally, was at least a big step ahead of others in the game.

Due to the persistence of parents, Ashelua, who had just returned to the dormitory the day before school started, immediately pressed the switch of the magic computer.

The touching boot screen appeared on the screen. Ashelua had to be grateful that she chose to come to Crescent Academy based on the principal's appearance.

However, what made Ashlua curious was that the familiar icons on the screen had changed and there were more programs. Although she wanted to click on what these programs were for, her rationality still made her stop her actions. After all, if it was some very troublesome programs, she would not be able to handle them.

Ashelua first clicked on the Snake's game rankings, and as always, F was still browsing the rankings. She opened the chat program again. In an instant, a series of sounds surrounded her.

"I haven't read these people for only a month, and I've already had more than 999 messages?"

Ashlua sighed that they were energetic and opened the chat window. After turning over two pages, she couldn't turn the record.

Although these people are in the game discussion group, the topics they usually talk about have almost nothing to do with the game. Looking around, what dishes are all about how to make better food, what novels are good, what novels are very bloody, and how to match clothes to better look topics.

However, there is one thing that attracts Ashlua in this long list of chat records, that is, the pictures interspersed in the text.

These pictures are different from the rough hand-painted versions that Ashlua accidentally saw before the holiday. They are all redrawn exquisite versions, not only look neat and unified, but also more vivid.

For example, there is a mark with a funny expression. Although it looks like a smile on your lips and squint your face, you will feel that it has a different meaning when you think about it carefully.

For example, a marked expression of laughter and crying, a crying expression with two tears on the upper part of the face, but a laughing mouth opens, vividly expressing the feeling of crying with joy.

These expressions are mixed between language, greatly enhancing the expressiveness of the text, and even making some sentences with distinct meanings with distinct meanings.

Ashelua was soon attracted by these expressions. She read the chat records with expressions one by one. According to the situation, the people in the discussion group had formed some popular usages of emoticons during the period when Ashelua was away. She looked at it for a long time before she roughly understood that after she felt that language was really a profound knowledge, Ashelua tapped the keyboard and typed the first sentence in the discussion group after the New Year.

Pudding: Happy New Year everyone, I'm back (funny).

f: So actually adding a little salt to the dough will make it easier to ferment?

f: Ah, welcome back (applause).

Mona: It's okay to use expressions.

Claire: Welcome (applause) (applause) (applause).

Black Tea: I always feel that this group will grow and grow this year (helpless).

Claire: Isn't this a good thing (funny).

f: By the way, it seems that a new game will be launched in a few weeks, which is completely different from the current model.

Black tea: What type? (Question)

f: Otherwise, ask Claire?
