?In the military camp, the generals under Yuwen Wenhe who had just recovered from a serious illness are arranging various matters for the withdrawal of troops. Today, the commander of the army, Yu Wenming, has officially ordered Yuwen Wen's new army to return to Anlu. The departure date is three days later. At that time, a new army will take over their defense.

The so-called military orders fell like a mountain. In order to ensure that they could set off on time, Yuwen Wen did not dare to take it lightly. Although he could set off with the new army's "packing" ability in the future, he still summoned the masters to implement the details of the withdrawal one by one.

"This march first starts from Jiangling to Hanjin and pass through the Han River and then heads to Anlu." Yuwen Wen gestured on the map with a branch. This time he returned to Anlu, which was considered to be a march to the northeast, which was not convenient to use water transportation, so it was the whole journey of land.

"There are about 1450 miles from Jiangling to Hanjin, and about 3230 miles from Han River to Anlu, and the whole journey is about 480 miles. Our army will arrive in Anlu within ten days from the day of departure, based on the daily marching of our army for fifty miles per day."

The normal daily marching speed of the army's long-distance marching is between 30 and 40 miles. Yuwen Wen's requirement for his army is fifty miles, so the day to return to Anlu is about three days faster than the date specified by the military order.

"There may be the same marching routes as ours, so the supply of food and grass along the post station may not be enough." The military leader Chen Wudi took over the conversation, "Master Xu Zhuang, if you want to count the good food and grass tomorrow, please enter the city and make an adjustment."

"The owners of each building are responsible for the withdrawal of troops in the building. The drainage ditches in the camp must be retained, and the places where the urination and drowning are buried, and the fences of the camp are not destroyed."

"Calculate the injured and sick people, take the car on the day of departure, and report the number of people tomorrow morning to prepare the carriage."

"The weather has been rainy recently, so the supplies trucks are ready to prevent rain, and prepare more ginger so that soldiers can drive away the cold after getting wet from the rain."

Yuwen Wen handed over to the military leader Chen Wudi and the masters to formulate a withdrawal plan. He was not the kind of military leadership style that was so big that he liked to work together. As the saying goes, a hero and three helped him think that he didn't have the ability to do everything, so he would brainstorm.

After discussion, Yuwen Wen announced the meeting and then inspected the military camp. Because of the military camp's defense, the facilities in the military camp need to be retained so that later generations can continue to use it. He walked around and checked from time to time and checked it, half an hour passed without realizing it.

"I'm leaving." Yuwen Wen looked back at Jiangling City and murmured to himself. He didn't expect that many things would happen in just over a month. Although they were full of dangers, they had a lot of rewards. It was considered a "public and private sacrificing".

"Zhang Yu. You go to the city to do two things."

"Wangzhu, what are the two things?"

"First, notify Manager Wang to pack up his luggage, and of course Miss Xiao. Tell them the departure date."

"Second, bring that Zheng Tong to the military camp to see me."

......

In the camp, Yu Wen Wen was sitting behind the desk holding a book, while on the side was sitting with a "fake ma-coat god-like appearance" Zheng Tongqi, there was a pen, ink, paper and inkstone on the desk. Now it was the time for the "interview".

"Now there is a square field. Guang, from each 56 steps, I asked the geometry of the field." Yuwen Wen asked as he looked at the contents of the book.

Zheng Tong picked up the pen and calculated for a moment and then replied: "One thirteen acres, sixteen extraordinary steps."

"How can it be calculated?"

"The fifty-six steps of laying the fields, and you will get 3,136 steps by multiplying them. You can get it by eliminating them by a mu method."

"Now there is Guitian, from thirty steps, one end is wide and twenty-four steps, and the other end is not. How much is the field?" Yuwen Wen asked another question, Guitian is a triangular field. This question asks how to calculate the area of ​​a triangular field.

The book he held was "The Book of Five Catholics". This book was written by Zhen Luan, a mathematician of the Great Zhou Dynasty. The five Catholics were Tian Cao, Bing Cao, Ji Cao, Cang Cao, and Jin Cao. It represents the five types of problems. It is the official mathematics education book of this era, which tests the administrative calculation ability of officials.

Zheng Tong picked up his pen and wrote on the paper for a moment and replied: "One acre, one hundred and twenty steps."

"How can it be calculated?"

"List one end to a wide range of twenty-four steps, get twelve steps in half, and get 360 steps multiplied from thirty steps, and get it by dividing it by the acre method."

Yuwen Wen unfolded the military service in "The Five Causes Calculation" in a volume of military service. This volume of military service refers to the mathematical problems in the allocation of military personnel and the transportation of food and grass. I just asked about the Tian Cao Book, which is related to the calculation of the field area.

"Now there are 23,692 Ding and 5,923 soldiers, and ask how many Ding will send out a soldier?"

Zheng Tong replied: "Six Dings send out one army."

"Now there are 10,000 people, ten generals, twenty subordinates, one hundred generals, nine hundred and eight hundred and seventy-eight scattered soldiers, and there is a difference between the silk: the general gives three zhang, two zhang, and one zhang, and five zhang. The scattered soldiers give nine zhang, how much do you ask for advice?"

Zheng Tong took the pen and calculated it on the paper for a moment and replied, "Two thousand two hundred and seventy-five pieces, three feet apart."

"There is a city that is 48 miles away. If you want to order the enemy to fight against the bandits, you will place one army every three steps. How many soldiers should be used?"

"Four thousand eight hundred people."

Yuwen Wen opened the collection of Cao Book again: "I have made it last year and I want to have one hundred and fifty hu of millet. Now there are three people. I have got five hu of wheat when I make it in four days. Now there are seven people who have made it in one month. How much does it cost to sell?"

Zheng Tong made up for a moment and replied: "Eighty-seven hu of five dou"

"Now there are 849 hu of beans, and nine dou of beans are easy to make them numb and seven dou. How much does it mean to ask?" Yuwen Wen thought again.

Zheng Tong made up for a moment and replied, "Six hundred and sixty hu, three dou, three liters."

Yuwen Wen opened the warehouse book again. Jin Cao Book each chose several calculation questions to ask questions, and Zheng Tong all calculated the correct answers. He nodded and then clapped his hands and asked someone to come in and put the book away.

"Mr. Zheng's numerical skills are good," Yu Wen Wen showed praise. Tian Cao, Bing Cao, Ji Cao, Cang Cao, and Jin Cao involved five aspects of calculation problems that grassroots officials have to face. "Ji Cao" is a trade exchange problem, "Cang Cao" is a problem of grain taxation and warehouse cellar volume, and "Ji Cao" is a problem of silk fabric trading and other issues.

He did not want to recruit a math teacher, but used this method to judge whether Zheng Tong, a person who claimed to have been a "turbid official", was exaggerated. Zheng Tong claimed that he started from the grassroots level and climbed up step by step, but his career was not good, and finally lost his official position. Yuwen Wen could not retrieve Zheng Tong's "files", so he could only use the Five Caos to calculate the classics and attack indirectly.

If you say you have done the work of measuring the fields, you must at least know how to calculate the area of ​​square, triangle, and parallelogram. If you say you have done the transfer of military food, you must at least know how to classify military food supply and rewards.

When it comes to grain collection, you need to know the granary category and related volume calculation issues. If you have done barter, you should know the offset ratio between various items. You must also have arithmetic ability. At least you will not be fooled when collecting grains and then you will be confused about the results. When reconciling the accounts, you will find that you cannot match. Yuwen Wen needs talents but does not need a "clear flow" that can only talk about.

More than empty talk? I also plan to build an internal combustion engine! Do you know how to extract uranium\235?

Yuwen Wen roughly judged through the question just now that Zheng Tong was indeed a grassroots minor official with a higher level of government affairs. Li Shimo removed the pen, ink, paper and inkstone in front of Zheng Tong. After he walked out of the camp, Yuwen Wen suddenly asked: "Mr. Zheng, where is the scar on the back of the man's hand just now?"

Zheng Tong twisted his beard and said, "Mr. I was joking. The man's hands and hands were intact and there was no scar."

"How many moles are there on the face?"

"Both places, both on the right eyebrow."

Zheng Tong has a very strong observation ability. Yuwen Wen has seen that a man who can play the "Ma Yi Shen's appearance" on the street and speaks a lot of people's appearances naturally needs to make a living by observing words and expressions, and of course he must also be able to clichés from others.

However, it is not a simple thing to be able to maintain this kind of observation at any time. Now it seems that the other party has developed professional habits and can never forget everyone's appearance characteristics. Yuwen Wen feels that this is also related to Zheng Tong being a grassroots official, and observing his words and expressions every day has become instinct over time.

"Zheng Tong, I will fight against the clerks in the future. Do you have confidence?" Yuwen Wen said seriously. He no longer called the other party "Mr." and claimed that he also used "Mr.".

"Mr. I have a lot of experience and will definitely be competent." Zheng Tong stood up and said, "Since he lost his official position, he could only mess with people on the street to support his family. Until he ran into Yuwen Wen, the second son of the Anzhou general manager, who wanted to seize this opportunity that was inadvertently placed in front of him.

This was his chance to change his destiny, the only chance. Liang State was too small. All promising official positions were occupied without his room for promotion. He lost his official position because of evil, and he would not have the chance to rekindle his life. With his wife, he could not go to other places where he was unfamiliar with his life to make a living, and he could only live in Jiangling and struggle.

There was an authentic tunnel in Zheng Tong's house that could lead to the palace, so that night he noticed something was wrong and gritted his teeth and waited in the street near the Loquat Gate to "lead the way". Yuwen Wen, who was stationed at the Loquat Gate, led his troops into the city and rushed towards the palace.

God blesses him to make this contribution, but just leading the way may not necessarily give him a meal, so he still has to work hard. Since that day, Yuwen Wen has not given himself a chance to recommend himself, so Zheng Tong is a little restless, and today is the "critical moment". Since the other party has given him the opportunity, he must seize the opportunity.

Sooner or later, Yuwen Wen will become a state official. If he can join the school, he will at least have the opportunity to break out of another official path. Whether it is Liang, Zhou, or Chen, the clerks are like crows in the world. The clerks who deceive their subordinates and conceal their superiors are so confident that they have to deal with these "comrades".

"Very good. I don't like nonsense. Three days later, I will lead the troops back to Anlu. You should take your wife and children to set off with the army." Yuwen Wen was very satisfied with Zheng Tong's performance, at least now, he would be very satisfied with the state officials in the future. In the future, he would have to deal with grassroots officials. If he dealt with it improperly, he would be fooled by the clerks.

"Dream of Dreams and Bi Tan" written by Shen Kuo of the Northern Song Dynasty once recorded this incident: When Bao Zheng was aware of Kaifeng Prefecture, someone broke the law and was exiled after being a stick. The prisoner privately gave the clerk a lot of money to agree to perform a bitter meat show in the lobby.

When Bao Zheng sat upright in the hall to try the case, the prisoner did not plead guilty and kept making defenses. Before Bao Zheng could speak, the clerk loudly scolded the prisoner for despising the court and shouted out to take the blame for serving the prisoner.

Seeing this, Bao Zheng was very angry and thought that the clerk was out of power and ordered the clerk to be dragged out of the pole. At the same time, in order to show his magnanimity, Bao Zheng ordered the prisoners to be forgiven and punished with pole to be punished and not exiled.

Even Bao Qingtianyi, who was like a god, would be trapped by the clerk if he didn't pay attention. Yuwen Wen didn't think he would be better after becoming a state official. At that time, his father would send someone to help him, but after all, he was not considered a "person". He wanted a cat to deal with those mice who were full of tricks and hidden skills.
