The Most Romantic of the Three Kingdoms

As winter approaches, another news comes from Chang'an. http://%77%77%77%2e%76%6f%64%74%77%2e%63%6f%6d

It was Dong Zhuo who scrapped the five baht money and replaced it with "little money".

Five baht money is a currency that has been in common use since the former Han Dynasty. The so-called "five baht" is not only the money written on the money, but also the weight of the money, one two to twenty-four baht.

But Dong Zhuo is now abolishing the five baht coins and changing them into small coins, which obviously will cause great damage to the coin production.

The news said: Dong Zhuo's "little money" is about the weight of one five-baht money.

What does this represent?

It means that in the best case, in the most ideal case, ten small coins can only be used as one five baht money.

This will inevitably lead to inflation. Things that can be bought with one dollar can only be exchanged for ten dollars.

Along with the news, they arrived at Guangling, as well as several "little coins" newly created by Dong Zhuo.

Xun Yu took the money and flipped it twice in his hand, then held it in front of him and looked at it carefully. After reading it, he passed the money to Chen Qun, who was sitting below him, and turned to Xun Zhen and said, "Your Majesty, this is the case. Money is light, and the casting is poor. You can't even see money on the surface of money. Twenty money is probably not worth a five-baht money."

Chen Qun looked at the money and passed it to Cheng Jia, who was next to him, and also said, "Dong Zhuo has gone so madly, I mourn Chang'an and the people."

It is conceivable that prices in the surrounding areas of Chang'an will skyrocket as a result, and the lives of ordinary people in these places will be even more difficult.

Zhang Hong, who was sitting across from Xun Yu, said, "Dong Zhuo pretended to use the decree of the imperial court to order this money to be used all over the world. I don't know what the lord and lord meant about this?"

"This kind of money, of course, can't be used."

Zhang Hong nodded and said, "I also mean the same thing. Once this money passes through, the state and county will be in chaos."

Cheng Jia looked at the money in his hand and said, "I heard that Tao Gongzu was in Tan County to privately cast five baht for military expansion, but I don't know if he would use small money instead?"

Xi Zhicai, who was sitting on top of Zhang Hong, said, "If he dares to use small money, it would be the best for me, Guangling."

Cheng Jia smiled and said, "Then he probably wouldn't dare to switch."

Xun You said, "Even if he dares to change it, who would use it?"

Cheng Jia replied, "That's true."

Everyone was talking about small money, Xun Zhen saw Guo Jia and Xu Zhuo sitting at the end of the table silently, so thoughtful, he called the two of them and said, "Fengxiao, Yuanzhi, and Qing are quiet. Sit silently, but what's on your mind?"

Xu Zhuo and Guo Jia looked at each other, got up and left the table, and bowed down to the hall.

Xun Zhen asked in surprise, "Why do you suddenly perform this ceremony?"

Xu Zhuo said: "Yesterday I heard that Junhou wants to send an envoy to Pengcheng. Zhuo and Jiagan are in love with him, and are willing to speak to Xue Li for Junhou."

Xun Zhen laughed and said, "I thought you two had something to do, but it was for this. You two get up first."

Xu Zhuo and Guo Jia agreed to get up.

Xun Zhen said, "The candidate for going to Pengcheng has been decided, but it's too late for the two of you."

"I don't know who the prince wants to send to Pengcheng?"

"Xuande has asked for it himself."

It was Liu Bei who went on the line with Xue Li for the first time on behalf of Xun Zhen. This time, as soon as it was rumored that Xun Zhen was going to send another person to see Xue Li, Liu Bei asked to see Xun Zhen last night and took the job early.

Guo Jia said, "Jia and Zhuo are willing to serve as assistant envoys to Liu Jun."

Xun Zhen smiled and said, "Why do you need Sanjun to go to a small Pengcheng? Xuande alone is enough."

Guo Jia and Xu Zhuo invited him again, but Xun Zhen just refused.

These Guo Jia and Xu Zhuo are the two backup forces that Xun Zhen is most optimistic about, and they are ready to be used in the future.

Seeing that Xunzhen insisted not to allow it, Guo Jia and Xu Zhuo, although eager to make contributions, had no choice but to return to their seats.

Seeing that the two of them seemed unhappy, Xun Zhen smiled and said, "I left you two in Guangling because I have other important tasks to entrust to you."

Xu Zhuoxi asked, "Dare to ask what is the important task?"

"There are two things I have always wanted to do, but the time has never been ripe. Now it can be done. I am going to leave these two things to the two of you."

Hearing Xun Zhen speak so formally, Guo Jia couldn't bear it any longer and asked, "Jun Hou, what's the matter?"

"One is that I want to set a set of rules for map surveying and mapping, and the other is that I want to make a set of sand table war games."

Not only Xu Zhuo, Guo Jia, Xi Zhicai and others heard Xun Zhen's words, but they also looked at each other, not knowing what Xun Zhen meant.

Xi Zhicai said, "Map surveying and mapping?"

"Exactly. You don't need me to say it, you know how important maps are when it comes to marching and fighting. An accurate map can be said to be invaluable. But the surveying and mapping of the current map, in my opinion, has There are shortcomings, so I want to summarize the strengths of each family and formulate a set of rules for map surveying and mapping, so that we can better draw military maps and facilitate our army to use them in the future."

Xu Zhuo asked, "How do you want to formulate it?"

"How to formulate it depends on you. I can only tell you a few principles."

"Zhuo and others dare to hear it."

"I have a few things in mind for a while: First, we need a scale, so that we can distinguish the distance from the near; second, we need to have high and low, so that we can distinguish the difference between high and low; third, we need to have undulations, so that we can distinguish the difference between the **** and the plain."

Although the current map is definitely not as accurate as later generations, it basically has everything like what Xun Zhen said, but no one has formally summarized these things together and proposed a set of general guidelines. Xun Zhen didn't know, but in fact, just a few decades later, a person named Pei Xiu in the Wei and Jin Dynasties formally proposed a "six cartography". These, and more, are almost the same as the principles of later surveying and mapping.

Xun Zhen has seen a lot of current maps, both civilian and military. Compared with the maps of later generations, he also found that there are many things in the maps of later generations, such as scales, The undulating lines and even the things that are similar to the contour lines already exist. Compared with the maps of later generations, the biggest problem with the current maps is actually that they are not accurate enough.

Xun Zhen really wanted to improve this, but he was not good at mathematics, so he couldn't give guidance in this regard, but it didn't matter, he was not good at mathematics, and he was good at mathematics.

Xun Zhen added: "Apart from these points, the most important point is: distance, height, and height, you must be precise."

Xu Zhuo asked, "Precise? What do you mean by Junhou?"

"You can ask a few scholars who are proficient in arithmetic to help compile a set of teaching materials for surveying and mapping distances and heights."

Xun Zhen was not well versed in arithmetic, so he did not know whether the algorithms used in later generations to survey and map maps existed, but when he thought about it, he probably did not. However, he had a little understanding of the current arithmetic, and knew that only his current arithmetic achievements, such as If used properly, even if the map still cannot be as accurate as later generations, it can reduce many errors and increase a certain degree of accuracy.

Xun Zhen didn't know it, but it was still a few decades later, at the same time as Pei Xiu, there was another person named Liu Hui, who was a famous mathematician at that time. He had a book called "Nine Chapters on Math" , in which there is a volume called "Heavy Differences", which is the enlightenment work of practical trigonometry, and studies the measurement problems of high, deep, wide and far.

Xu Zhuo likes the military, and he has fought in Xunzhen for many years. He knows the importance of maps to the military, so he took the initiative to ask Ying and said, "Zhuo is willing to take this post."

Seeing Xu Zhuo taking this position, Guo Jia had no choice but to accept the sand table war chess job. He asked, "Jun Hou~www.wuxiaspot.com~ What is sand table war chess?"

"In the past, when Guang Wu attacked Kui Xiao, General Fu Bo gathered rice in front of the emperor to form a valley, drew pictures of the situation, and taught the path. Do you know this story?"

"knowledge."

"What I'm talking about is sand table wargames, it's just a little more complicated than that."

"How complicated?"

"In addition to the geography of mountains and rivers, there are also various types of arms, and then according to the actual combat situation, such as the speed of cavalry marching in the valley, such as the speed of infantry marching in the mountains and forests, and the respective injuries that may occur when the infantry and cavalry engage in frontal engagement, etc. Wait, according to these actual combat situations, make a set of rules, and then use this to deduce the occurrence, progress and results of the war."

Guo Jia is so smart, when he heard Xun Zhen's explanation, even if he understood what Xun Zhen meant, he also understood how much help this sand table war chess set would be to his own army if he could make it. Of."

Zhang Hong listened to Xun Zhen's instructions and requirements on the two matters of surveying and mapping maps and making sand table war chess. He sighed without realizing it: "If these two weapons are complete, the prince and prince will be even more powerful. I know how the prince and prince can do it. A hundred battles are won."
