After Mo Cheng left, Ling Yu was idle again, now that his status is high, as long as he is told, someone will handle all kinds of things, although this makes Ling Yu a lot easier, but sometimes it makes Ling Yu very boring.

"Xiao Ling, do you think it's possible for us to make something like a computer?" Ling Yu asked Xiao Lingdao boredly.

"Master, this is a bit difficult, but it's not impossible, I think we can also create a better foundation for building computers by integrating the satellites and communications we talked about before." Little Lingdao.

"Okay, I'm just bored to ask, how are you doing with the communication tools you talked about earlier?" Ling Yu asked.

"Master, through this period of research, I deduced the communication rune, this communication rune simulates the way the walkie-talkie generates communication signals, a range of terminals are under the coverage of the host that depicts the identification rune, can achieve multi-person real-time communication, just like a walkie-talkie like a band coverage, but it is not far away, it can probably cover more than 10 kilometers, it is not bad to command operations, but to achieve long-distance calls, it is still necessary to establish something like a base station to relay and receive signals, Change the identifier to the unique terminal identifier to make it a function similar to a calling card, and then each terminal can talk within the signal coverage range of the base station through this identifier. Xiao Ling explained.

"Xiaoling, do you mean that the walkie-talkie can already be realized?" Ling Yu was lazily leaning on the sofa just now, and when he heard Xiao Ling mention the walkie-talkie, he immediately jumped up.

"Master, the walkie-talkie has a certain utility now, but the range is not yet as good as the telephone described in the information." Little Lingdao.

"That's not bad, this thing is not big, you quickly give me the blueprint, I'll get it out and try it." Ling Yu was excited, with this thing, it would be very convenient to communicate and command on the battlefield in the future, and even in Jinling City, building something similar to a small base station might be able to achieve a small-scale communication function similar to a telephone.

"Okay master, I'll transfer the blueprints to you." Xiao Lingdao, she is also very happy, after such a long time, according to the information in the database, she has finally designed a communication tool that can be used.

Ling Yu received the design drawing, studied it carefully, and found that the structure is actually very simple, roughly divided into two types, one is a host that depicts the identification rune, and then can receive and forward the signal emitted by the communication rune within 10 kilometers, but this signal is not an electromagnetic wave, and Xiao Ling does not know what kind of signal it is for the time being.

Through this host, all terminals in the coverage area can communicate in fact, as long as the terminal is turned on, press the call button when you want to talk, you can speak, of course, all the terminals under the coverage area can receive, however, you can also set up a plurality of different identification hosts, and the communication for different situations is divided into different frequency bands.

The base station communication method that Xiaoling said is used as a relay, receiving a communication signal with a unique identifier from the terminal, and forwarding it to the terminal with this identifier to achieve private calls.

Ling Yu decisively chose the second type, and directly skipped the first one, but if necessary, he would still use the first type, such as the battlefield.

However, the coverage area is still too small, and I am afraid that if the range is exceeded on the battlefield in the future, either a base station will be built to cover it, or a signal corps will carry a logo host to relay signals.

Ling Yu didn't drag it anymore, and quickly went to the workshop, planning to do it himself and lead people to make it.

Wu Yong went to prepare the hot air balloon materials, and Yang Yuan was left in the base, which would be organized to set up a field near the workshop, and when he turned his head, he saw Ling Yu coming over in a hurry.

"Master Hou, my subordinates are leading people to build a venue, but it hasn't been built yet, I don't know what else Master Hou has to order." Yang Yuan hurriedly stepped forward and said respectfully.

"Well, you go ahead, send me something, I want to make something, I don't need you to follow, I'll take them to do it myself." Ling Yu said quickly.

"Yes, Master Hou, please come with me." Yang Yuan looked at Ling Yu strangely, he didn't know why Hou Ye was in such a hurry, but he didn't ask too much, organized the craftsmen in the workshop, asked them to obey Ling Yu's arrangement, and went out to continue to build the venue.

Ling Yu didn't delay much, commanding the craftsmen, manufacturing various parts according to the design drawings.

After a few hours of busy work, Ling Yu finally built a logo host and two test terminals, the host does not look big, it is about the size of a shoe box, there is a spirit core, all the runes are concentrated on the spirit core, and the natural volume does not need to be too big.

The terminal is also not big, it is about the same size as the Nokia brick machine after 00 years in another world, there are two buttons on it, one is to press the button of the call, the other is the identification button, after pressing it, and then press the call button, you can send a communication signal with a unique identity to the host, and the other terminal can receive it.

Because it is the first generation, it is very simple, and the terminal that receives the signal will also directly play the voice, confirming that the unique identification is also through the button, which is of course inconvenient, but the first generation, Ling Yu also does not ask much, he wants to test the feasibility of this method.

Of course, the indicator light is also set to prompt the current status, for example, there are three lights on the host, one is the light that shows the running status after it is turned on, and the other is the light that shows the signal passing, whenever there is a signal receiving or forwarding, this light will flash, and the last one is reserved to display the lights connected to other identification hosts.

Connect other identification host in order to be able to increase the signal coverage, after connecting, the host will communicate with another host, when the only identification terminal that needs to transmit the signal is not found in the coverage area of this host, the signal will be transmitted to another host to continue searching, until it is found, it is very advanced.

On the terminal, it is simple, there are two lights, one is the status light that shows the host connected after it is turned on, and the other is the light that flashes when sending and receiving signals.

Ling Yu looked at these communication tools excitedly, and finally made it, and in the future, the identification host will cover the capital, wouldn't it be easier to find someone, but the current means of confirming the unique identification are still too simple and crude, but it can be slowly improved.

Originally, Ling Yu was going to wait here for the men and horses of the other 4th Army to enter the base, but this will create this communication tool, Ling Yu will no longer wait, he plans to go to the palace to try it out with the emperor, he doesn't want to offer treasure, but this kind of equipment can be said to be a strategic tool now, so naturally too many people can't know.

Even the craftsmen who worked with him didn't understand what it was.

Ling Yu returned to the barracks and explained to Yu Feng who was training, and asked him to arrange it when a few other people came, after all, Yu Feng had been here for a while, and he was familiar with the base barracks, so it was okay to hand it over to him. 187

He used a box to contain the communication equipment he had just created, put it in a storage ring, and drove into the palace.

In the imperial study, Zhou Zhengxiong was a little surprised after receiving the news that Ling Yu asked to see him, according to his understanding, shouldn't Ling Yu be reorganizing the army and making hot air balloons at the base? Could it be that something is going on?

After the ceremony, Zhou Zhengxiong looked at Ling Yu and asked, "Ling Aiqing, how is the situation of today's training?" Aren't you supposed to be at base? How did you get into the palace? ”

"Your Majesty, Wechen went to the base early this morning, everything has been arranged, and the four generals have each returned to the camp to select soldiers, Wechen's idea is that each army will pick out 2 divisions of people to train, after all, the number of these Beijing troops is not in line with the establishment of the new army, and it is necessary to take into account the existing defense, so Wechen made this arrangement, as for the hot air balloon, Wechen has ordered the Academy of Sciences to prepare, due to the large size, it is necessary to prepare a lot of materials and build a dock-like site, which will not be completed for a while and a half."

"Well, I don't have an opinion on your method, do you want me to solve something when you go to the palace to find me? Could it be that the generals of the Beijing army are too rebellious? Zhou Zhengxiong frowned and asked, he suddenly thought that the people in the Beijing army were all arrogant generals, although Ling Yu had a holy decree, but after all, he was still too young.

"Your Majesty, no, the generals of the Beijing army are very cooperative, and Weichen has not encountered difficulties." Ling Yu hurriedly explained that he was not here to sue.

"So what are you doing here? Idle? Would you like me to find you something to do? Zhou Zhengxiong listened to it and quipped.

"Ah, Your Majesty, to get down to business, that's the case, before Wechen went on the expedition, I felt that our communication method was too troublesome, so at that time I began to design a convenient communication tool, after this period of research, Wechen finally designed a communication tool, because the stakes are very high, so Wechen personally entered the palace to face the saint and report this matter to His Majesty." Ling Yu explained.

"Communication tools? I think it's very convenient, with 800 miles of urgency, what else is faster than this? Zhou Zhengxiong asked puzzled, but he was also aroused by Ling Yu.

"Your Majesty, Weichen's communication tools are much faster than these 800 miles, and it can be said that the communication can be completed within a few seconds, and there is no need to send someone to deliver the letter at all." Ling Yu said proudly, he didn't look down on this ancient so-called 800 li expedited.

"In a fraction of a second? Ling Aiqing, what are you dreaming about? Zhou Zhengxiong said with some amusement.

"Your Majesty, please look." Ling Yu took out the box containing the communication tools and put it on the ground, then took out the host and two terminals and said: "Your Majesty, this is the communication machine that Weichen just made, a host can cover instant communication within 10 kilometers, as long as both sides are holding the terminal, real-time dialogue can be achieved, and through the connection of multiple hosts, a larger range and longer distance communication can be realized." Ling Yu took the terminal and pointed to the host and explained.

"Oh? And such artifacts? If I cover the whole country with this host, wouldn't I be able to talk to me anywhere in the Great Week? Zhou Zhengxiong was shocked, and he quickly thought of this.

"Your Majesty, theoretically speaking, it can be realized, but now it is the first generation of products, and the coverage area is only 10 kilometers away, which is too small, if you use this kind of machine to cover the whole country, the cost is too high, but you can use it to cover the capital as a test, and the terminal is only the first generation, Weichen has only built two, and it needs to be further improved." Ling Yu said with a smile.

"Hehe, Ling Aiqing, you can always surprise me, hurry up and try it over there, right here, Yucheng, you cooperate with Ling Aiqing." Zhou Zhengxiong said excitedly.

"Yes, Your Majesty." Yucheng led the order and walked over.

Ling Yu handed him a terminal and told him how to use it, then asked him to leave the imperial study, find a random place, it was best to go farther, and then hand over another terminal to Zhou Zhengxiong, and also teach him how to use it, then turn on the main machine, and the rest is to wait.

After about half an hour, Ling Yu estimated that Yucheng should go away, so he asked Zhou Zhengxiong to press the identification button.

After Zhou Zhengxiong pressed the button, the button fell into the body, and then he pressed the call button, and said with a smile: "Yucheng, can you hear my voice?" ”

After a few seconds, Yucheng's voice came from the terminal: "I heard it, Your Majesty, the slave maid heard it." Yucheng's voice was very excited, like a child who has received a new toy.

Zhou Zhengxiong also became excited and asked, "Yucheng, where are you now?" ”

"Your Majesty, the slave is now talking to you in front of the gate of the Golden Palace." Yucheng's voice was full of surprise.

"Haha, it's really possible, the imperial study is three or five kilometers away from the gate of the Golden Palace." Zhou Zhengxiong said excitedly.

"Okay, Yucheng, come back, don't let people see it." Zhou Zhengxiong smiled and ordered, this matter is still confidential for the time being, if the enemy knows, he doesn't know what kind of changes will be caused.

"Ling Aiqing, I don't know what to say anymore, so I won't say more, according to what you said before, use this kind of host to cover the Jingshi, and make more terminals, but do it secretly, don't let some people find out." Zhou Zhengxiong said.

"Yes, Wechen obeys." Ling Yu bowed and promised.

"Well, you are another great achievement, I haven't rewarded you last time you returned triumphantly, so let's reward it together this time, and when the meritorious deeds of the meritorious soldiers are counted this time, they will be rewarded together at the court." Zhou Zhengxiong said happily, with this thing, he knew how good it would be.

"Thank you for your grace." Ling Yu said respectfully.

"Well, that's it, by the way, except for Bin'er, no one else can know about this matter, you remember." Zhou Zhengxiong instructed.

After Yucheng came back, Zhou Zhengxiong consulted Ling Yu on how to place the host, and Ling Yu carefully explained to Yucheng how to place and use the host, and then went back to follow Zhou Zhengxiong's intentions and prepared to step up the manufacture of a batch of hosts that could cover the Beijing Division.
