Listening to the sound of the gunshot, Qin Chuan thought about the shooting competition for a while, and wanted to go back quickly if he wanted to sue Nie Shicheng, but was about to speak, but Feng Guozhang asked inquiringly. Pen ~ fun ~ pavilion www.biquge.info

"Lord Qin, there is absolutely no problem with the defense map of Seoul you drawn, not to mention that none of these people who participated in today's competition are incomparable, even better than those German instructors, this first place is none other than Lord Qin. It's just that Guozhang is stupid, and I don't know what Lord Qin means by these circles on the map? I also asked Lord Qin to make it clear in order to solve Guozhang's or. ”

Feng Guozhang's question, Qin Chuan couldn't get away for a while, and he couldn't help but regret that he had done too much, so he had to patiently explain to Feng Guozhang and Nie Shicheng.

"These circular patterns are not drawn at random, they are called contour lines, but I came up with the idea when I was working on the map, which can mark the elevation of the surface and mountains on the map, as well as the shape of the mountains, so that the person who looks at the map can clearly understand the height of the mountains on the map, and the terrain is soothing and towering, which is extremely beneficial to those who set up positions with map prediction."

Qin Chuan pointed to the simple terrain of Seoul that Feng Guozhang had placed on the ground with some regret and said: "It's just that the mountains around Seoul set up by Huafu did not give the elevation, and even the situation of the mountains and rivers did not have any markings. ”

Being able to see the height of the mountains and the topography on the map at a glance through the map, this method is the first time Nie Shicheng and Feng Guozhang have heard of it, especially since this is what Qin Chuan himself understands, and they can't help but be surprised and admired.

Feng Guozhang hurriedly asked: "Lord Qin's contour line is extremely clever, and it is not beyond the power of a person of great wisdom, but how to draw this contour line will be accurate, and please teach me Lord Qin." ”

Qin Chuan knew that he would definitely not be able to leave, and seeing that Nie Shicheng was also impatient, he had no choice but to explain aloud to the two of them amid the continuous and dense gunfire.

"If it is the top of a peak, the contour line is closed, and the value of the elevation of the peak gradually decreases from the center to the periphery; If a basin or depression is described, the contour line is also closed, indicating that the regional elevation of the center of the basin or depression gradually rises from the center to the periphery; In the case of a ridge, the contour protrusion points to a lower elevation. The contour line protrudes from high to low, which is the ridge; In the valleys, on the other hand, the contour contour protrusion points to the higher elevations; The saddle between the two adjacent summits is indicated by a blank space without drawing a contour line; Gentle slopes and steep slopes and steep cliffs, and the overlap of contour lines is a cliff. The denser the contour line, the steeper the terrain, and the sparse place, the more gentle the slope. In other words, from the density of the contour line, you can see how gentle and steep the terrain is。。。。。。 ”

Qin Chuan saw that Nie Shicheng and Feng Guozhang listened to their explanations of the use of the contour line, not only listened attentively, but both of them had a look of surprise in their eyes, and thought that in the upcoming First Sino-Japanese War, all the generals of the Qing army who participated in the battle were not suitable for commanding a large army on a large scale. So much so that in the entire First Sino-Japanese War, except for Nie Shicheng's Wu Yijun and others, who could only talk about the performance of a few parts, the performance of the rest of them was extremely stubborn, and they couldn't help but sigh secretly, and simply told the two of them about the use of military maps one by one.

“。。。。。。 The scale of the military map can be 1:50,000 or 1:100,000, and the spacing of the contour lines on the map can reach 5 meters, which needs to represent the water system, the ferry, the water depth of the ferry, the location and load of the bridge, the soil quality of the river bottom, and the cultural background of the soldiers. The current military maps of various countries are inappropriate, and the individual symbols, line and surface symbols involved in the standard ideal military maps have been greatly improved, and even in terms of color. If the map drawn according to Qin is used to direct the operation, the angle, distance, slope, coordinates, elevation and area can be measured from the map, and not only can the terrain be explored, but also the artillery can be determined to involve Zhuyuan and command the large corps to fight。。。。。。 ”

While Qin Chuan explained to Feng Guozhang, he moved Feng Guozhang's mind again in his heart.

"Huafu, this contour line is like this, the effect must be clear to you, the military significance is very significant, if used accurately, even if a commander has never been to a certain place, as long as he sees such a map, he can design and build fortifications based on such a map, choose an ambush location and arrange an offensive route。。。。。。

"Hua Fu, although the idea of this contour line is wonderful, it is not the most proud thing I have realized, Qin thinks that he is very talented in military affairs, when you have time, we will discuss it carefully。。。。。。

"Hey, Lord Qin."

Nie Shicheng interrupted Qin Chuan's very seductive words with a smile: "Today, Lord Qin's words have made Nie Mou suddenly open up, and he has learned a lot, and when Nie Mou comes back from outside the gate, he will definitely ask for advice." However, Lord Qin should stop fighting Hua Fu's doctrine, I have already been enlightened to Lord Zhongtang, after Hua Fu's proofreading today, even if he is in my Wu Yi Army, Hua Fu is a leader in the drawing homework of the Martial Arts Academy, I am about to take him to inspect outside the customs, and now with Lord Qin's wonderful method, Nie will be even more powerful, and this trip will definitely gain a lot of money. However, it looks like we need to find a few more surveyors. ”

Seeing that his mind was seen through, Qin Chuan's face couldn't help but be a little sneering, so he had to look at Feng Guozhang.

Feng Guozhang smiled bitterly, and bowed to Qin Chuan: "Lord Qin's cultivation intention Guozhang is deeply understood, but Lord Nie appreciates it below, and he doesn't dare to disobey it." Moreover, Lord Nie deeply felt that Japan and Russia coveted my Kanto land and ambition to die, so he took the initiative to ask to go out of the customs to inspect the terrain and materials, in order to prepare for the need for war outside the customs on a different day. Now there is the method taught by Lord Qin, and it will definitely be prepared everywhere to facilitate the needs of the future. ”

Feng Guozhang's words made Qin Chuan stunned for a long time, not because he could no longer beat Feng Guozhang's attention, but he really didn't expect that Nie Shicheng would have such a lofty mind, and now he could think of going to the gate to investigate the terrain and materials outside the gate to prepare for war.

Grandma's, who said that the Qing Dynasty military generals were incompetent, this Nie Shi's achievements are very revealing.

Qin Chuan suddenly remembered that before crossing over, he seemed to have read a book called "Journey to the East", which was a book describing the topography and geography of the mountains and rivers outside the Guanwai, and there were many topographic maps of the Qing Dynasty's military works, and that book was signed Nie Shicheng。。。。。。
