In fact, the conditions in this world to be able to generate infinite communication that Reiner is familiar with are already in place, not to mention that in the Rainbow Tower, magic has achieved this, so Reiner naturally doesn't have to worry about hardware problems.

What he needs to improve is the algorithm.

As we all know, the earth's communication uses radio carrier communication, which is simply the process of modulating the signal to a band that is convenient for transmission, and then transmitting it over a long distance, and then demodulating the party that receives the signal to obtain the original signal.

According to the Newington-Holland equations, electromagnetic waves travel in a straight line with a speed equal to the speed of light and can be reflected by objects such as metal sheets, so Reiner could easily build his own 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 that, he only needs to work on the hardware, build a device that can modulate, demodulate, send, and receive radio signals, and integrate it into a magic computer.

A week before the end of the winter break, Sur returned home to Crescent Academy, and to be honest, after being exposed to magic computers and programming code, Sur really fell in love with the job, and these careers rekindled her research heart that had been dormant for many years, and she felt uncomfortable not seeing a magic computer for a day, so she came back early.

In the following week, students came to the school one after another to report, and in the new year, students naturally had new expectations, and they exchanged their experiences during the New Year, among which the most talked about was the Crescent Moon Cola 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 daughters to Priest and took advantage of the end of the holidays to have a good time.

According to the rules of the theme park, the students of Crescent Academy can enter at half price with their student certificate, which is the school badge, which also makes these students who like novelty talk and wait for the weekend to go again.

The two projects they discussed the most, one is the thrilling roller coaster, and the other is the unpredictable Fort William, according to the information that the students pieced together, the route and content in Fort William are not exactly the same, even if it is the same route, the strange events encountered are not the same, the students are speculating about what is being used to achieve this, for a while, the number of books about necromancy and illusion in the library has increased exponentially.

What confuses the students even more is something else that appears in everyone's dorms.

It was a black, box-like thing, with a wire connected into the wall, and it wasn't clear what it was for, until the day before the start of school, a notice appeared on the public bar on the wall of the common room of the dormitory, telling everyone the specific purpose of the black box, and at the same time, it was also announced that starting this semester, all grade level students would add a compulsory but non-credit-bearing course, learning how to use this device called a magic computer.

Seeing this notice, Ashirua and Hathaway suddenly had a sense of joy sneaking away, and Hathaway, who was already able to write code independently, naturally needless to say, Ashilua was at least a big step ahead of others in the game.

Due to her parents' insistence, Ashilua, who had returned to the dormitory the day before the start of school, had just returned and immediately pressed the switch on the magic computer.

A touching boot screen appeared on the screen, and Ashilua had to congratulate herself on choosing to come to Crescent Academy based on the principal's appearance.

However, what made Ahirlua curious was that several familiar icons on the screen had changed, and there were some more programs, although she wanted to click on them to see what these programs were for, but reason still made her stop her actions, after all, if it was some very troublesome programs, she couldn't handle it.

Ashilua first clicked on the game leaderboard of Snake, as always, F was still brushing the list, she opened the chat program again, and in an instant, a series of dripping sounds surrounded her.

"These people, I haven't read them for a month, and I already have more than 999 pieces of information?"

Ashilua sighed that they were energetic, and clicked on the chat window, only to turn two pages and then 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, and when you look at it, it's all about what dishes are more delicious, what is good-looking, what plot is very bloody, and what clothes look better with them.

But one thing that caught Ashilua in this long list of chats was the pictures interspersed with the text.

These pictures are different from the shoddy hand-drawn versions that Ashilea had seen before the holidays, they are all delicate repaints, which not only look neat and uniform, but also more expressive.

For example, there is a funny expression, although at first glance it is just a pouting smile and squinting at the round face on the side, but when you think about it carefully, it feels profound.

Another example is an expression marked as laughing and crying, the upper part of a face is a crying expression with two tears, and the lower part is laughing with an open mouth, vividly expressing the feelings of crying with joy.

These expressions are interspersed between the words, which greatly enhances the expressiveness of the text, and even gives a different meaning to some sentences that are originally distinctive.

Ashlua was quickly attracted by these expressions, she read the chat history with expressions one by one, and looked at the situation, the people in the discussion group had formed some popular usage of emojis during Ashilua's absence, and she looked at it for a long time before she roughly figured it out, and after feeling that language was really a broad and profound science, Ashlua tapped the keyboard and typed the first sentence in the New Year's Eve discussion group of the Crescent Moon Game.

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

F: So actually adding a little salt to the dough makes it easier to leaven?

F: Ah, welcome back (applause).

Mona: It's okay to be able to use facial expressions.

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

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

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

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

Black tea: what type? (Question)

F: Why don't you ask Claire?

Claire: It's not me, I don't know, don't ask me.
