The night was deep, and Xue Shao was still writing and painting in the study.

The moon slave called to fetch three basins of hot water to wash Xue Shao's feet, and when he saw that he had not yet fallen asleep, he couldn't help but persuade: "It's dark at night, why don't you rest early?" If you are busy, you can do it again tomorrow. After all, the body matters. ”

"You go to sleep, you don't have to wash. You're going to have my feet peeled off. Xue Shao's pen did not stop.

"Yes." Seeing that Xue Shao was busy and didn't dare to bother more, Yue Nu responded very obediently and then bent down to put on his socks and shoes.

Xue Shao glanced down at her and smiled slightly. Although Yuenu is a female man with strong martial arts, she is careful and gentle when she does these things, and I seem to have become accustomed to her serving and taking care of her.

"The son rests early, and the moon slave retires." The moon slave carried the foot-washing water and retreated outside the room.

"Moon Slave."

"Does Childe have any orders?"

"Thank you." Xue Shao smiled.

The moon slave trembled slightly, and hurriedly lowered his head, "The moon slave doesn't dare!" The moon slave is a lowly slave maid, and it is a matter of course to serve the son! ”

All the people in the Tang Dynasty have the distinction of "good and low". The good ones include the common people such as the Shinongshang, and the lowly ones are criminals, slaves, prostitutes, beggars, and miscellaneous musicians. The law prohibits good and bad men from intermarrying each other. If you have money, you can raise a few prostitutes to play, but you can't marry a wife, even if you are a concubine, otherwise you will wait to be reported and punished!

Even the children born to the master's family by the lowly slaves and maids can't get rid of the lowly status!

Xue Shaoran smiled slightly, "Another day, I will tell the yamen that I will exempt you from your cheap status and let you be a beloved." ”

"Childe forgives sins!" The moon slave was shocked, and hurriedly put down the basin and knelt down, "The moon slave no longer dares to be reckless, beg the son not to drive me away!" ”

"Who said they were going to kick you away?" Xue Shao smiled: "Aren't you happy to be exempted from cheap status?" ”

"It's fun to be happy, but the moon slave just wants to stay with Childe! Although the world is big, the moon slave doesn't want to go anywhere! Yue Nu raised his head, surprised and happy, and looked at Xue Shao with a hint of confusion.

"Of course it's good if you want to stay, anyway, I won't drive you away." Xue Shao smiled indifferently, "After getting rid of the lowly status, you are an upright person, isn't it bad?" ”

"Thank you for your mercy!" The moon slave's eyes turned red, and he hurriedly kowtowed on the ground, "The moon slave is willing to follow Gongzi I and serve left and right!" ”

"Alright, get up, go back and rest." Xue Shao said indifferently.

"Thank you, Childe!" Yue Nu kowtowed a few more times, then got up and picked up the basin, looked at Xue Shao faintly and deeply several times, his pretty face was red, and he quietly left.

In the social form of the Tang Dynasty, the good and the low are like a chasm, which is not so easy to overcome. Slaves and maids of lowly nationality cannot be regarded as "people" in essence, and can be arbitrarily bought, sold, exchanged, and beaten and scolded by their masters, just like livestock. Therefore, Xue Shao said that the removal of the lowly status of the moon slave is tantamount to giving her the opportunity to straighten her waist and be a new person, and she can be protected by the law from now on, can run her own family business freely, and marry and have children in the name of justice.

It is not easy to do such a thing as "getting rid of the lowly status and returning to a beloved", and it is not something that the master can do if he agrees. The "qualification examination" on the part of the government is quite strict and cumbersome, and it is easy to change from a good status to a low one, but it is even more difficult to change from a good one to a good one. If you don't have a little identity and connections, you really can't do it.

But Xue Shao is a nobleman, and his words are enough to change the lives of Yuenu and her descendants.

"That's the power and beauty of power." The corners of Xue Shao's mouth were slightly raised to the top of the mouth, revealing a playful smile, and he continued to write.

He has a copy of "Jade Chapter" as a reference book in his hand, which is equivalent to a dictionary of Chinese characters, which includes more than 16,000 Chinese characters, which can be regarded as an enhanced version of "Shuowen Jie Zi". Referring to the "Jade Chapter", Xue Shao is transcribing a codex.

Each page of the Codex has nine columns, each column contains nine words, never repeated, and each page is numbered. In this way, each word corresponds to an accurate coordinate from the page number to the number of columns and the word order, all of which are represented by Arabic numerals. For example, the fifth character of the seventh column on the first page of the word "person" is represented by a numerical code, which is 175.

Xue Shao cataloged some words that were often used, such as one, two, three, four, five, generals, soldiers, horses, and horses, and the victory or defeat of flag rice and grain.

Yes, Xue Shao is compiling a set of Datang version of the "Morse Code" secret code book.

Although the telegraph has been completely eliminated and replaced in the 21st century, it is still high-tech when it comes to Datang for application. Xue Shao couldn't invent and create a "telegraph machine" for a while, but it was no problem to compile a unique set of secret codes.

The army has never been without the transmission of information back and forth, otherwise how can we talk about commanding operations? However, in order to prevent the enemy from intercepting military letters, the ancient army would use "military secret codes" to avoid leaking military secrets.

In today's Tang army, or in the Chinese army before modern times, it uses an extremely simple "military secret code". Before setting out on the expedition, the generals discussed the use of a poem without repetition to represent different meanings. For example, in the sentence "autumn water grows together in the sky", everyone agreed to use the word "water" to represent the meaning of "reinforcement of grain and grass". Then when it comes to the wartime front, when a certain unit wants to replenish grain and grass, it will write a very vague letter to the rear, asking for help, such as "Brother Dashui has been sent at home and return quickly", and then a stamp is stamped on the top of the word "water", which means "requesting reinforcements of grain and grass".

In this way, the purpose of transmitting information can be barely achieved, but the information that can be conveyed is very small. If it is intercepted, it is easy for people to recognize at a glance that this is an encrypted "military secret letter", and it is not difficult to decipher.

But if Xue Shao's method is adopted, it doesn't matter if he tells the enemy that this is a military secret letter, if he wants to torture the messenger who sent the letter, it is impossible to judge the ugly man - he doesn't have a secret code book to compare!

Even if the secret code book is snatched by the enemy, it doesn't matter. There can be multiple secret code books to be replaced, and the word order is completely different.

Moreover, such a "ninety-nine" Morse secret code can be applied to many fields, such as commercial use. Now Datang does not have a bank or a bank, if there is one in the future, who else can forge or claim the "silver ticket" made with such high-end encryption technology?

This set of codes can even use the oldest methods to convey information, such as drums and horns. Especially when going deep behind enemy lines to carry out underground activities, fingers knocking on the table, or the fire flickering and even blinking eyes, who can decipher it except those who are proficient in this set of secret codes?

The Datang version of the "Ninety-Nine Morse Code" is really useful!

Xue Shao secretly laughed while transcribing, the homework of "encryption and decipherment" in the army back then was really not in vain, those high-tech electronic and secret techniques aside, the Jin merchant ticket number plus secret techniques, the dominant Morse code during World War II, and even the black words such as Hongmen incision, can all come in handy when they are flexibly adapted to local conditions by Datang.

With such a high-end "encryption technology", Pei Xingjian, as a smart person and a military master, can't see its value and not be tempted?

This is a special gift that Xue Shao wants to give to Pei Xingjian.

"There's nothing Morse to do. Name this new set of encryption techniques - Lantian Secret Code! The smile on Xue Shao's face was full of confidence and humor.

After dawn, Xue Shao practiced Baduan Mianhe Xingyi Quan as usual, and when he was about to go to wash and eat, he saw You'er getting together with two laundry aunts in the patio of the servant's room, "Hey, hey, hey" waving a small mallet to wash clothes there.

"Didn't I say that you won't let the demon do these things?" Xue Shao walked over and said, "She's thin and small, and her health is not good, when is there a shortage of labor like her in the house?" ”

"Childe forgives sins!" The laundry aunt hurriedly said, "The slave family has also been persuaded hard, but the demon girl doesn't listen, she has to rush to do these things, and she can't stop it!" ”

The demon hurriedly put down the laundry hammer and knelt in front of Xue Shao, "Kowtow to the fairy brother!" ”

"Get up, the bluestone is hard and the ground is full of water, what do you kneel." Xue Shao pulled her up, "You'er, why didn't you listen to what I told me, what kind of clothes did you come to wash?" ”

"I'm ......" You'er stood up, blinking her eyes a little in fear and pitifully, "I'm just a lowly outcast, I can't eat and drink all day for nothing, I should do more!" ”

"Didn't I tell you to study well? If you read the books well and learn the things I teach you, it will be of much use in the future than washing 10,000 clothes a day! Xue Shao smiled and patted her weak shoulder, "Come to my study after breakfast, I have something fresh to teach you!" ”

"Yes, Brother Fairy!" As soon as the demon heard that there was something new, she immediately grinned, revealing a pair of small tiger teeth.

After breakfast, Xue Shao called the housekeeper Chen Xinghua to the study, wrote a letter with his own private seal, and said to Chen Xinghua: "You take my name sticker and this letter to Lantian County Yaran, and apply for a good person's household registration for Yuenu and You'er." If there's something you need to spend money on, you just have to do it. ”

Xue Shao knew that he was not a figure in Chang'an, and the threshold of the yamen in the capital was also very high, so it might not be so easy to get things done.

"Childe is going to get rid of their lowly status and give them as lovers?" Chen Xinghua's eyes widened in surprise. This kind of thing may be just a gesture for Xue Shao, but it is difficult for low-level people to reach the sky!

"Yes." Xue Shao said, "You go and check my land over there again." Now it's time for spring ploughing, and it's time for the tenant farmers to get moving. ”

"The old man will leave for Lantian County." Chen Xinghua respectfully accepted the name sticker and other things.

"There is Mr. Lao Chen. Remember, their last names are all 'An', safe and sound. You've got the name in mind. Xue Shao said, "Go, by the way, help me call the demon here." ”

"Yes, Childe." Chen Xinghua is very curious, what is the surname "An"?

Xue Shao picked up the tea with a smile and took a sip, the moon slave and the demon are the most "intimate" people I have met since I came to this world, they should not be cheap slaves.

Later, the demon came, "...... to the fairy brother"

"Don't kneel, come here." Xue Shao smiled and called her to the desk, spreading out the secret code book, "Do you know all these words?" ”

The demon looked at it for a while, smiled and blinked with a pair of big shining eyes and nodded, "Brother Fairy, I recognize it!" ”

"Good." Xue Shao rubbed her hair, "I memorized them all in the shortest possible time, and I can't even remember the location!" Otherwise, spank you! ”.
