"Father, today I learned some new painting techniques from Chen Fei, the guard of the left prison, who joined the army, but that Chen Fei joined the army a little colored!" Li Lizhen said in front of Li Shimin.

And this young man, who was probably only in his twenties, then stroked Li Lizhen's little head, and then said, "What's wrong with him?" ”

"He actually drew a man without clothes, saying something that makes us familiar with the structure of the human body. However, that Chen joined the army very colored. Li Lizhi continued to point out Chen Fei's "**".

"Since you don't want to learn beauty, let him teach you landscape painting, don't learn the portrait of this kind of character." Li Shimin said dotingly.

Then Li Lizhen reported what Chen Fei said to her today, and Li Shimin heard the hope that these two little girls would not hate each other, and Li Shimin inevitably smiled bitterly. It's all come to this point, and their fathers will want to die in the future, can they not hate each other? I'm afraid, it's difficult!

Then, Li Lizhi took out an envelope, and this envelope was very huge, which made Li Shimin a little surprised. And this envelope looks thick, and I don't know how many things are inside. And Li Shimin saw that the envelope was sealed with fire paint, which also proved that no one had opened it.

"This is Chen Fei joining the army and letting the child give it to his father, I haven't opened it and read it!" Li Lizhi said.

After Li Shimin took the letter, he opened the letter and found that there were many pieces of paper inside. Li Shimin began to look at it in order, and then frowned, obviously a little surprised by this.

"Auxiliary, look at this! This was sent by Chen Fei, who was the left guard of the left prison guard, who you told me, when he joined the army, as if this was talking about a method of information encryption. Li Shimin said to the eldest grandson Wuji.

And the eldest grandson Wuji is the person in charge of some of Li Shimin's confidential information, so he quickly saw this encryption method with years of experience. This encryption method actually uses some dots and horizontal lines to represent different letters and numbers, and then these letters are concatenated into different syllables. Then these syllables are transformed into Chinese characters again, and so the content of the article comes out. And the eldest grandson Wuji suspects that these syllables are actually a new initial vowel system, and this eldest grandson Wuji is not too proficient in this.

"King Qin, these things composed of points and horizontals should be a new secret language system. However, with the current ability, Yichen can't understand this thing very well. Although he explained it in great detail, the minister is not a person who is proficient in this way, so he needs better people to help the minister understand. However, if this secret language can be made, then the ability of our Tiance Mansion to keep secrets of documents will also be greatly improved. Although I don't know how this Chen Fei came up with these dots and horizontal marks, and then become a new rhyme again, we can be sure that confidential letters will never be lost. The eldest grandson Wuji said.

"Go and call Master Kong!" Li Shimin said to the servants beside him.

And the eldest grandson Wuji can be sure that this is a very good encryption technique. Although encryption and decryption take more time, as a confidential letter, how can there be a lack of time to decipher the password! Therefore, the eldest grandson Wuji is also very interested in this new cryptographic system. However, this needs a master of sound and rhyme to assist him to solve it. As for the vocal masters in King Qin's mansion, who else can there be besides Kong Yingda?

The eldest grandson Wuji couldn't have imagined that this was actually something that Chen Fei made up based on the Morse code of later generations. Chen Fei before the crossing, when he was a soldier, he often ran to the division's communication battalion, because he wanted to pick up a girl and a beautiful second lieutenant platoon commander in the communications battalion. However, this was made by those veterans of the army in later generations, and as a result, Chen Fei was thick enough, so he immediately opened his cheeks to ask for communication knowledge. Of course, in the name of asking for communication knowledge, it is the practice of picking up girls. And that beautiful ensign was helpless, so she had to teach Chen Fei a lot of things. However, these are already publicly available, such as this Morse code. Later, this beautiful second lieutenant was transferred to the headquarters of the army group as a communications staff officer. Then, there was no then.

However, Chen Fei also remembered a lot of Morse code, and now he will come over to get this eldest grandson Wuji and let him see his Morse code method. Originally, this Morse code could only be used to represent the English alphabet, but Chen Fei combined the Chinese pinyin of later generations, and it was completely possible to make the content into pinyin first, and then send it out again in the situation of Morse code. As for the translation problem, this is actually very simple, Chen Fei can download a later Morse code translation software, and then directly enter it in the future, and the content can be translated, and there is no need to use his brain to translate. However, Chen Fei didn't know if Li Shimin could accept this new type of Chinese pinyin.

Although Morse code was already the so-called "clear code" in later generations, it could almost be said to be a very tight cipher in ancient times, and ordinary people could not understand it at all. Therefore, Chen Fei's password was immediately valued by the eldest grandson Wuji, who had been doing this kind of secret work for a long time, so he began to study this new cipher system.

Since the beginning of human beings, there has been communication, and since the beginning of communication, there have been people who have paid attention to the secrecy of communication. And the ancients had an old saying that the king is not secret, and the minister is not secret, so secrecy has always been pursued by many people. And although the eldest grandson Wuji also had secret words in the past, he found that his secret words were simply weak compared to Chen Fei's Morse code. Because his secret language is all Chinese characters, as long as it is Chinese characters, it is possible to be cracked by the enemy. And once it is cracked, the losses suffered are very large, and this kind of thing is not without it before.

And Chen Fei's secret language system is all made by relying on points and horizontals, and if it is a layman, he can't understand it at all. And even if you understand the meaning of the dots, you have to translate it again into a new rhyme, so that you can crack it and become the real content. This kind of method of encrypting it twice is simply maddening, and I am afraid that in the future, the communication confidentiality ability of the Qin Wangfu will be increased by more than ten times.

"King Qin, Master Kong Yingda is here!" The servant said.

And Li Shimin took the initiative to say: "Master Kong, the Lone King has something for you to see, you help the Lone King take a look, what does this thing mean." The lone king and the auxiliary machine don't quite understand, you see what this means, and then talk to the lonely king and the auxiliary machine. ”

And Kong Yingda looked at it for a while, and then his face suddenly became very heavy, and then he was surprised: "King Qin, this is a great talent!" ”
