Zheng Zhi looked at these maps, and the more he looked at them, the more upset he became. Pen, fun, pavilion www. biquge。 info originally looked at the map of the Great Song Dynasty, but I didn't have this feeling, because in the northwest, out of Hengshan was a large area of grassland and desert, a horse and a flat river, and there were veterans and guides who were very familiar with the terrain.

For that kind of flat land, there is no problem with the map of this era.

But now when looking at the map of Jiangnan, the problem becomes prominent: it is really difficult to carry out military staff operations on a map without scale and contour lines, and there is no explanation from a person who is really very familiar with the terrain.

At this time, two words appeared in Zheng Zhi's mind, contour line and scale. The contour line is a detailed description of the topography, the topography of a mountain, the height of the terrain, are clear at a glance on the contour line.

The scale is an accurate depiction of distances, as well as detailed relationships between target points in the overall picture of the map.

Simple cartographic mapping is not a sophisticated technology. Rather, there is a simple way to implement it, and if you need a little more accurate surveying and mapping operations, the equipment you need is not particularly technical. The calculation method is the key core technology.

Simple surveying and mapping is also one of the basic skills that special forces need to master, and in turn, looking at the map to identify the direction and distance is also one of this skills.

Zheng Zhi looked at the map in front of him and thought about it for a long time, from the scale bar to the contour line, it naturally extended to the issue of military education. After extending to the issue of military education, Zheng Zhi had a feeling of a military academy in his mind, or a martial arts school.

Cultivating the military quality of officers also seems to be an important means to enhance the combat effectiveness of the army. From strategic vision to military strategy, in fact, it can be systematically cultivated.

Li Guang, the flying general of the Han Dynasty, is a simple and straightforward example, why did Li Guang die? Just because Li Guang followed Wei Qing to send troops to fight the Huns. The military plan made before setting off was after Li Guang led the troops out, and Li Guang got lost in the vast grassland.

When Wei Qing defeated Shan Yu and came back, he crossed the desert and met Li Guang, who was lost, and asked Li Guang why he didn't arrive, whether he had escaped from the battle. Li Guang committed suicide in shame because of this!

In the war of the cold weapon era, this kind of thing often happens, that is, the two armies are facing each other, you can't find me, I can't find you, many generals take their troops out for a trip, go around and around and don't see it and come back, waste money, food and manpower, especially when fighting with nomads, in the vast grassland, this problem is particularly prominent, which is also one of the reasons why the Han people rarely attack the grassland. The failure of many military programs is also due to this most basic problem of military qualities.

If you have a map with a scale, you need a staff officer or guide who can read the map. These problems can be completely avoided, and Li Guang, the flying general who "made Longcheng Fei and did not teach Hu Ma to Yinshan", would not commit suicide in shame. Military plans can also be formulated more rationally and better executed.

This is only the most basic point in military quality education.

Zheng Zhi looked at these maps at this time, and he was already thinking about it very intently, and the matter of military education was already brewing in his mind. From military quality to tactics and strategy, it is more and more important at this time. Originally, it was fine when he brought a few thousand soldiers, but at this time his subordinates had to be expanded to 50,000, and these problems were especially important in this era when communication and dispatch were backward.

Wu Yong took Deng Xian to the small hall, looking at Zheng Zhi who was sitting on the ground looking at the map in a daze, Wu Yong didn't dare to bother, just stood at the door and waited.

Zheng Zhi thought about it slowly, came back to his senses, and looked at Wu Yong at the door and said, "Pedant, help me find a guide who is very familiar with the terrain of Jiangnan and Liangzhejiang in the afternoon." ”

Wu Yong listened, his mind turned, and he looked at Deng Xian beside him, and hurriedly replied: "Xianggong, this person next to me is happy to do it." ”

In this era, businessmen have to travel all over the country, especially Deng Xian, a businessman who does silk and satin cloth business, naturally has to run around in the south of the Yangtze River and Zhejiang, from buying raw silk, to weaving into cloth, to bleaching and dyeing, and then to shipping it out to sell, these things have made this Deng Xian travel all over the south.

Deng Xian heard Wu Yong's words, and knew that the person sitting on the ground must be the official above Wu Yong, so he hurriedly stepped forward to salute and said, "Villain Deng Xian, please meet Xianggong." ”

Zheng Zhi glanced at Deng Xian, and he was not polite, and said, "Come over and have a look, and ask you a few questions." ”

Deng Xian hurriedly stepped forward to Zheng Zhi's side, watched Zheng Zhi gesture back and forth on the ground a few times, and asked, "What is the straight-line distance from Jiangning to Hangzhou?" How far is the journey and how many days does it take? ”

Zheng Zhi's mind was full of questions on the map at this time, so he didn't bother to be polite back and forth, that is, he didn't bother to ask who Deng Xian was.

Deng Xian didn't even look at the map drawn by Zheng Zhi, and said: "According to the villain's business experience for many years, the straight-line distance from Jiangning to Hangzhou should be about five hundred miles, and the distance is about seven hundred miles. If you are transporting goods on foot, you can reach it in about 10 days. ”

Deng Xian's experience is naturally not much worse, and the accurate straight-line distance from Jiangning to Hangzhou should be two hundred and thirty kilometers, and about five hundred miles is not much different.

When Zheng Zhi heard this, he turned around and went to get the pen and ink on the case, and instructed Wu Yongdao: "Go find a ruler." ”

Wu Yong wanted to open his mouth to ask Zheng Zhi to eat, but his words were also blocked at this time, so he had to quickly go out to find a ruler. In the Song Dynasty, one zhang was equal to ten feet, one foot was equal to ten inches, and one inch was equal to ten. One inch is equal to 3.7 centimeters. Of course, for metrics, whatever unit is used is the same, as long as there are standard units, the calculation is the same thing.

After a while, Wu Yong took a ruler, and Zheng Zhi lay on a map and measured it, from Jiangning to Hangzhou, one foot and six inches. The actual length of 500 li is about 31 li of land.

After Zheng Zhi measured it, he didn't raise his head and asked: "How far is the straight-line distance from Jiangning to Suzhou?" What is the geometric route? ”

Deng Xian naturally couldn't understand what Zheng Zhi wrote on the map and what the amount was, but he also hurriedly replied: "The straight line is about 400 miles, and if it is a road, it should be around 600 miles." ”

Zheng Zhi began to measure the distance from Jiangning to Suzhou on the map again, one foot and two inches. Zheng Zhi calculated a little, and one inch was about thirty-three miles. It was two miles away from the previous calculations, and the one-foot map distance was only twenty miles away. Although there is a problem with this scale, this map is already relatively accurate, and this result makes Zheng Zhi breathe a sigh of relief, the ancients' means of making maps are not as backward as Zheng Zhi thought.

In fact, Zheng Zhi didn't know that the theory of the ancients making maps was actually not bad, and it was basically the same as the theories of later generations. The difference lies in the technology of mapping, which is mainly the technology of surveying and mapping calculation.

The method of making maps in ancient China is called the "Six Bodies of Cartography", which includes the division rate (scale), Zhun Wang (direction), Daoli (distance), Gaoxia (undulating terrain), Fang Xie (inclination angle), and Roundabout (the straightness of rivers and roads).

The inventor of this method is called Pei Xiu, who was born in the late Eastern Han Dynasty and was a talent from the Three Kingdoms to the Western Jin Dynasty. It can be seen how wise the ancient Chinese were. It's just that it is far from modern times in terms of surveying and mapping calculations, and there are no contour lines that can depict the terrain and contour differences.

At this time, Zheng Zhi looked at these maps again, and his sense of trust increased. Naturally, his expression was much more relaxed. The map error is only within a small range, and it is not a gap between the two sides that I feared.

Wu Yong saw that Zheng Zhi's expression was a little more relaxed, and hurriedly said, "Xianggong, it's time for lunch." ”

Hearing this, Zheng Zhi got up and put the pen ruler back on the desk, and said, "Scholar, find someone to inform the room and ask them to bring the food here, and we will eat here." ”

Wu Yong nodded, and there was a servant sent by Wang Hanzhi at the door, and after a few words, he came in again.

At this time, Zheng Zhi asked Deng Xian again: "Jiangning goes to Hangzhou, to pass through Guangde, and then to Huzhou, is this official road good?" How many days will the fast horse go? ”

"Prime minister, this official road is extremely smooth, but now the official road is controlled by thieves, I'm afraid it won't be possible, if it was in the original, there was a fast horse that could run, within four days, it would definitely be there." Deng Xian replied respectfully, and seemed to understand what this prime minister was doing.

Zheng Zhi was silent when he heard this, he was already thinking of a risky plan in his heart, but now, time was too short, and Zheng Zhi had already germinated the idea of adventure in his heart.

Wu Yong stepped forward at the right time and said: "Xianggong, this person's name is Deng Xian, his ancestral home is from Liyang, Jiangning Prefecture, and he has lived in Jiangning for three generations. ”

The imperial examination in the Song Dynasty was only divided into three levels, state, province, and palace. If you have passed the state exam, you are lifting. There is no child test Xiucai said, Xiucai does not need to take the test, most of the scholars can directly participate in the state exam, after the state exam is to lift people, and then the provincial exam, it is no longer a local exam, but an exam held by the Ministry of Rites under the Imperial Court Shangshu Province, which is already to enter Beijing to catch the exam.

The Ming and Qing dynasties were different, and Xiucai needed to be examined, so naturally there were many old children with gray hair who could not pass the exam. And the Song Dynasty only said that he was a talent who could not be examined. In many novels in later generations, the Song Dynasty said that the examination of Xiucai was ridiculous.

Zheng Zhi heard Wu Yong's introduction, turned his head to look at Wu Yong, and then looked at Deng Xian, and knew in his heart that there was a deep meaning, but he also remembered what happened last night, so he asked, "But the person who was in the painting boat last night?" ”

"That's the man." Wu Yong replied. In fact, there is no need to say anything, Wu will stop at the point, and Zheng Zhi will naturally understand some things.

Zheng Zhi nodded and said, "Well, the pedant is far-reaching, and the pedant will do this well, and there is no need to report more, just talk about it in the future." ”

Zheng Zhi didn't bother to ask in detail in front of Deng Xian. But Wu Yong's general intentions, Zheng Zhi also knew it. In this way, it also gave Wu Yong enough trust.

Wu Yong listened to the words and didn't say much, just bowed his hand, but his heart was extremely comfortable, and following behind such a smart and generous person as Zheng Zhi was also the blessing of a smart person like Wu Yong. The difference between Zheng Zhi and Song Jiang is revealed, Song Jiang's pattern is so different that Wu Yong, who is a military advisor, feels constrained and can't show the furrow in his chest.

It is completely different by Zheng Zhi's side, Wu Yong does not need to worry that he will not be able to show the furrow in his chest. On the contrary, he was worried that the furrow in his chest was too shallow to meet Zheng Zhi's needs.

After a while, the yacha brought food. Authentic rice and Jiangnan side dishes, the rice is sweet, the side dishes are light and delicious, plus some meat, the match is very appropriate, this is the life of Jiangnan people.

Although Zheng Zhi does not like the taste of this list, he is used to stir-frying heavy dishes with later generations. But such a meal is also enjoyable.

After eating, Wu Yongzheng was about to take Deng Xian out to continue his work. A handsome young man rushed in, it was Yan Qing, and there were also some dusty servants on his face, and not far behind, the soldiers and horses of Jiangning Mansion were all Yang.

Zheng Zhi saw Yan Qing come in, he had already gotten up, and asked first: "Xiao Yi, you set off yesterday evening and are back now, but the thief is not far away?" ”

After Yan Qing gave up his hand, he took a breath of relief and said: "Xianggong, the last general will take a few people back and forth quickly, and I have heard clearly, that Shibao brought about 10,000 thieves, all of whom were wrapped in cloth towels, from Xuanzhou into the territory of Jiangning Mansion, just past Kongjiagang, approaching Lishui County, and there is still a distance of seventy or eighty miles from Lishui. ”

Zheng Zhi turned around and looked at the map on the ground, and after finding Lishui, he asked, "How is the thief's armor?" How is the military formation? ”

"Xianggong, among the thieves, it is rare to see armor, and there are a lot of blades, but you can also see many people still holding wooden sticks, and the military formation is naturally not to be discussed, and everyone is wrapped in cloth scarves of different colors on their heads, which looks quite spectacular." Yan Qing only said that tens of thousands of people wrapped in turbans were quite spectacular, which meant that there was nothing else commendable.

Zheng Zhi naturally understood the meaning of Yan Qing's words, there is a lot of money, food and cloth in the land south of the Yangtze River, but there is a shortage of armor. It was not easy for Fang La to be able to make up so many blades. Zheng Zhi didn't even bother to ask if the thieves had horses, Bianliang was short of horses, and the ministers of the court and central government could only go out in ox carts, not to mention that in this Jiangnan, Fang La must not have a few horses, let alone the formation of cavalry.

At this time, there were tens of thousands of people in the vanguard of Fang La's general Fang Qifo all the way, which showed that there were a lot of people in Fang La's hands. According to historical records, Fang La was wrapped in millions. At this time, it seems that this history book may be exaggerated, but in Fang La's hands, there should be one or two hundred thousand people. Of course, there were only 120,000 people, 1.2 million people with knives, guns, and clubs. No wonder this Fang La has the confidence of Jianyuan, although this Fang La did not call the emperor, but this Fang La called himself "Holy Father", and also promulgated the year name "Yongle". Set up a system of officials and generals.

It's the same thing as being called an emperor, but the name of this "emperor" is changed to "Holy Prince". Only when the emperor ascends the throne will there be a year name.

Zheng Zhi stood still, flicked his sleeves, and said, "Help me put on my armor and order the school soldiers." Eat the pioneer of this square wax first and keep Jiangning. ”

Zheng Zhi had already regarded Jiangning Mansion as his base camp at this time, so he naturally had to drive Shi Bao, the vanguard of Fang Qifo, out of Jiangning Mansion first.

Niu Da, who had been standing aside, hurriedly went out and ordered a few soldiers to go out to give orders, and then turned around and came in to pierce Zheng Zhi's armor.

Wu Yong heard this, and already knew that he was going to send troops to fight, so he pulled Deng Xian out of the hall and commanded: "Deng Xian, the matter of purchasing goods will be handed over to you, and I will explain to the officials in this yamen later, and let them take the money to cooperate with you in doing things, keep clear accounts, and wait for me to come back in two or three days to check." ”

Deng Xian was shocked when he heard this, not shocked that Wu Yong trusted him so much, but shocked that Wu Yong swore that he would come back in two or three days. Busy said: "Pedant, the little one wishes the prince to go on the expedition and win the battle." ”

Wu Yong could see the expression on Deng Xian's face, although he could hear Deng Xian's wishes, but he also knew that Deng Xian was shocked and worried in his heart, so he smiled and said: "Don't worry, I will be back in three days at the latest, and this battle is not a problem." ”

When Deng Xian heard this, he hurriedly said: "The pedant must take care of himself in the battle array, the thief is powerful, and the pedant must return safely." ”

Wu Yong knew that this Deng was kind-hearted, but he waved his hand again and again and smiled: "More than 10,000 people who have just taken knives and guns are nothing, you can do things with peace of mind." ”

Deng Xian saw that Wu Yong was confident, although he was extremely worried and nervous in his heart, but it was not good to say more. Deng Xian was really worried that if he lost this battle, this Jiang Ning would immediately fall into the hands of thieves, and his gamble of weighing the pros and cons would also be a complete failure, and he would lose cleanly, and the savings of several generations would also be wiped out.

Wu Yong got up and walked to the yamen, Deng Xian followed, and only said in his heart: God bless, I hope everything is as Wu Xuexue said.

Just when Deng Xian was muttering in his heart that God would bless him, Wu Yong suddenly turned his head and admonished: "The acquisition must be accelerated, the more goods you buy, the better, and the price you can decide as appropriate." There is not much time left to buy cloth at a very low price, and it will not be available after three days at most. ”

Wu Yong's words naturally make sense, three days later, after returning victorious, who else will sell the goods.

When Deng Xian heard this, he arched his hand again and again: "Scholar rest assured, the villain will definitely mobilize all the people around him to buy cloth and iron, as well as fire and sulfur." ”

"Well, cloth iron is the main one, fire nitrate and sulfur are secondary, and Jiangning Mansion does not produce fire nitrate sulfur." Wu Yong explained things clearly.

The two of them went out of the yamen, and Wu Yong called the yamen to order these things.

A moment later, above the drum tower in the city, bursts of drums sounded, spreading throughout Jiangning City. There were also countless soldiers who galloped wildly and sent orders everywhere in the city.

All the ironclad soldiers from Cangzhou rode their horses to the yamen, and they were already beating drums to gather troops.

Zheng Zhi put on his armor, went out of the yamen, and sat on the horse. The iron horsemen who dared to come from all directions quickly gathered and began to point the school.

After finishing the school, Zheng Zhi didn't say much, and rode away, following left and right.

Only Zhu Long was anxious, and kept cleaning out the unwanted things on the carriage and moving them into the government office for temporary placement, and began to load the needed things again.

Just because the things that came to "grab" along the way were really varied, and the march was simple, naturally it could not be brought. But I just arrived in Jiangning yesterday afternoon, and I haven't had time to clean it up yet.

By the time Zhu Long set off with his baggage, Zheng Zhi had already led his troops out of twenty or thirty miles.
