After listening to Li Sanniang, I realized that now with the increase in cotton, there are many people working among the palace maids, but there are few people who can manage the accounts, and even fewer can do business.

The account management itself is also a layman for Li Sanniang, and there is no way, this time I am looking for the Ministry of Civil Affairs to see if there is a suitable person to support it.

Xiao Zheng patted his head and smiled bitterly, how could he forget about this, and called Liu Yijie to arrange things first.

The next morning, Xiao Zheng rarely arrived at Taifu Temple on time, and his move made Du Ruhui, who had just left the court, startled and thought that something big had happened.

asked Liu Yijie to call all the account offices of the treasury, and after waiting for a while, he saw that Li Sanniang brought more than 20 palace maids who were literate and intelligent from the factory in Yushan County to report.

Seeing that the people arrived to find an empty warehouse, a blackboard, for the first time how to systematically bookkeeping methods said, Liu Yijie since the last inventory of the warehouse found this bookkeeping method, a few children's calculation methods have long admired the five bodies, although from time to time to Xiao Zheng for advice, but also half-understood, but this time it is Xiao Zhun systematically taught these things, this is the master of the family does not pass on the treasure, people have taken him out today, if you don't learn to be sorry for yourself, don't say others.

Li Sanniang has long known Xiao Zheng's skills, but the palace maid she brought over can study with the officials of Taifu Temple for the first time. Although Datang is open to the people, the duel between male and female students is a precedent. The excited faces were red, and although the pencils in everyone's hands were crooked on the paper, Xiao Zheng was a little moved by the spirit of learning.

After speaking for an hour, he put down the chalk and said to everyone: "Ladies and gentlemen, the words of the non-saints taught below, but the lectures are all about the basis of arithmetic, if the words of the saints can establish the world and cultivate oneself, then the art of arithmetic can establish one's life, you don't worry, after mastering these numbers within two months, I will integrate the bookkeeping methods and principles, symbols and rules, including a certain unit of measurement, into words and numbers in the account book, and it will play a role beyond your imagination in the future."

Everyone stood up and bowed deeply to Xiao Zheng and said, "I'll wait for Xiao Gong's teachings."

After teaching for two days, Xiao Zheng found that Du Ruhui also sat in quietly to listen to the class.

"Lao Du, why don't you go to the court?" Xiao Zheng asked curiously.

"No, it's not for you!" Du Ruhui said to Xiao Zheng with a slashed face.

I didn't know until I asked, and I didn't know who spread the rumors of going out, and when I got to the Golden Palace, a group of old pedants began to talk nonsense. The officials headed by Xiao Yu and Feng Deyi said that Li Sanniang took the palace maid to learn arithmetic and these strange and obscene skills in the Ministry of Civil Affairs, which was offensive to morals and should be punished by the Ministry of Civil Affairs.

Du Ruhui definitely didn't do it, and for a while, the two sides were arguing with each other in the court, but this matter was defeated by the disagreement of reason and law. Li Shimin was also embarrassed to punish the crime of the Ministry of Civil Affairs, so he had to let Ji Chun pass the word in private to let Du Ruhui report his illness, and wait for a few days to avoid the rumors before going to court.

"These old bastards, when Lao Tzu was born and died in the Turkic camp, he didn't see them jump out, Lao Tzu pulled down his face to do business with the Hu people and seek wealth for the country, they couldn't see it, Lao Tzu shed a little blood for the Tang Dynasty soldiers, and let the craftsmen make helmets and swords day and night, they couldn't see it, and now Lao Tzu taught these people to add some practicality to me for the Tang Dynasty, they jumped out and said that it was a strange lewd skill, damn it, did Lao Tzu lewd his mother or his wife and daughter?"

"Hey! Pay attention, speak with a gentleman's style" Du Ruhui pestled Xiao Zheng with a pen, and then pointed to Li Sanniang and those palace maids and said.

I'm all stunned, there's no way not to be angry, Lao Tzu is hiding from you and letting you scold behind your back, and the mud people have to be angry.

After finishing the lecture in the afternoon, I went straight to the imperial study of the Xiande Hall to see Li Shimin, this guy smiled and said to Xiao Zheng: "Are you angry and complaining?" ”

"What are they doing with a bunch of sour Confucianism, the minister is here for the three-year appointment of the Turks," Xiao Zheng arched his hand and said to Li Shimin.

"Can you think of a good plan" Li Shimin suddenly became interested, sat up straight and asked.

"The minister has seen the map used by my army, and if he says something that should not be said, it is unsightly, so he asks His Majesty to transfer people to start with the map of the march."

"I've seen the picture you drew when you beat Li Yuanjing last time, and it's really exquisite, and it's more than a cut above the map in the army."

Xiao Zheng glanced at Li Shimin and thought to himself, since you know about this, then you still deduct Lao Tzu's salary.

"That picture was drawn by the supervisor worker, they know the benefits of that kind of diagram to learn so hard, and now the best way to use my Datang new unit of measurement is the supervisor craftsman, because they know the benefits here, so they will use it."

"Qing is saying that in the future, my map of the Tang Dynasty march can also be drawn like this?"

"Yes, but some matters and projects need to be considered in the long run, so the minister came over this time to ask the sage," Xiao Zheng said.

"I don't know what kind of person Qing needs to be competent for some things, although I will come to the Tao, I fully support it."

"If you want to make a map of the Turkic Western Regions, you don't need brave and warlike warriors this time, but people with skills, such as veterinarians, people who speak the language of the Western Regions, and more importantly, you must be loyal to the country."

"I don't understand? Why recruit such a person" Li Shimin was very puzzled.

"Among the Turks, only the medicine beasts or caravans could pass unimpeded."

"But the appearance of our Han people among the Turkic people will inevitably attract attention," Li Shimin was a little worried.

"We have cover, caravans, and it's a caravan of the Hu people," Xiao Zheng replied with a smile.

"And the basis of cartography is arithmetic, I want to let them see how much benefit this strange skill can bring to my Tang Dynasty," Xiao Zheng said coldly.

After listening to Xiao Zheng's words, Li Shimin sighed and said: "When I was in the Qin Palace, I was very praised by Qing for his "Secret Manual", this time I didn't expect that this arithmetic could be integrated into cartography, and I didn't expect that it could be a weapon for my Tang Dynasty to defeat the enemy.

A month later, the experienced scouts and meticulous workers among the guards of Chang'an City, including the people of the Hundred Cavalry Division, gathered in a secret place outside Chang'an City, and after screening, nearly a hundred personnel stayed. Xiao Zheng and the master craftsman Hu Zhongchun also began to make the drawing method and proportions, and these people also heard for the first time what a scale is, what is a contour line and a feature mark, it turns out that their own reconnaissance can still do this, and enemy information can also be collected in this way.

Hu Shang Du Yiti's home secret room, Xiao Zheng read out the secret decree of appointing Du Yiti, excitedly this guy hugged the holy decree tears down, although it is seven products, but it is a great affirmation for him as a Hu businessman, with this official clothes, if necessary, he has a higher status than the businessman in the Han, and he can still save his life when it is critical.

Three months later, these loyal and brave men of the Tang Dynasty mixed with the caravans of the Hu people and went to the Western Regions and the Turks to fulfill their mission......
