I have to say that people at this time still like to learn, and they are still willing to put down their shelves and accept different opinions with an open mind for what they don't know.

Wang Ke will not hide his 'private' for this kind of thing, he will say everything he knows, this is not how noble Wang Ke is, but he is too lazy, he doesn't want to do it at all, it's all 'handed over' to others, and if there is such a thing in the future, he will not come to himself again, so he can be idle.

Wang Ke said in detail the conditions needed to draw a map in later generations, the only thing that was not said was the problem of latitude and longitude, Wang Ke also thought that in this era, it is not much use to say this, now people think that the ground is a flat piece, if you now say that the ground is round, maybe you will dry your saliva, these people will not necessarily believe it, so simply do not say it, just talk about the proportion, elevation and so on. \\**

In fact, according to the requirements of Wang Ke to draw the map, when you want to make a sand table in the future, it will become easier, as long as the various elevations on the map are proportionally made into a three-dimensional model, you can soon make a scale 'fine', close to the original appearance of the sand table model.

These four people are not vegetarians, Wang Ke only needs to dial a little, a few people have already understood what Wang Ke means, based on the information in Wang Ke's hands, supplemented by the maps he used to draw by himself, comprehensively use the known data, and start drawing according to the few elements that Wang Ke taught them, Wang Ke stood aside and pointed from time to time, and when Li Jing came back, a map had been drawn almost halfway. \\**

Now in Wang Ke's eyes, this map looks like a little bit of a modern map, the contour lines of various terrains are there, reduced according to a certain proportion, the slope of the mountain, the width of the river, the direction are very clear, and the position of the road on the hill is also marked very clearly.

Li Jing saw such a map, of course, he was also excited, the previous map could only be a rough idea of the location, there is a mountain in front, how high it is not clear, the road passes through the mountain, what is the shape of the mountains on both sides, I don't know! If you want to camp, it looks like an open land on the map, you may walk in front of you, the open land is an open land, but there is a big slope, which is not conducive to the camp of the army at all, this is a frequent occurrence, now if you follow Wang Ke's drawing method, these can be avoided, in terms of efficiency, it will be much faster.

Looking at the map that is slowly taking shape, Wang Ke is still not satisfied, but now there is only such conditions, in this time crunch situation, it can only be carried out by using the existing data, if you want to really meet the standards in Wang Ke's mind, it can only be one way, that is, the people sent out to collect topographic maps must learn the several elements of drawing maps that Wang Ke said, and put every detail according to the requirements. In this way, the map drawn out can be as realistic as possible and lay a good foundation for the army to go on the expedition.

Wang Ke was a little unimpressed by Li Jing's argument, Li Jing only looked at the problem from the perspective of the military, but this map was not for the military, and it was also very useful for merchants to traffic long distances, so if there was such a detailed map in hand, it would be much more convenient along the way.

Wang Ke said to Li Jing: "Uncle, this map is not just for the army to march and fight, for the imperial court, there can be a full map of the Tang Dynasty, a full map of each province, and a full map of each state capital, which is conducive to officials at all levels to have a clear understanding of the area under their jurisdiction, that is, it is also an extremely useful thing in the people, merchants traffic goods over long distances, and people visit relatives and friends, all of which are useful, but now we are focusing on the use of the army, and when I Datang pacifies the Quartet and stabilizes, These maps should be drawn slowly. \\**”

As soon as Wang Ke stopped, before Li Jing could speak, he heard a round of applause behind him, and a voice said: "It's a good discussion, it's really 'fine'." But it does make sense, when this matter is over, the old man will definitely recommend Lord Wang to the emperor to complete this matter. ”

There is no need to ask, Wang Ke and Li Jing both know that this will not be the words that can be said by those old killers, it must be those civil officials who will say things that sound so civil, but if they can say it in this tone, there will not be a few civil officials in the Manchu Dynasty, after all, there are only a few who can recommend to Comrade Li Er who to do what, in Wang Ke's words, that is, it can be counted with one hand.

Now Wang Ke and Li Jing both know that if they come, they will not run out of one of the few people they are thinking about.

Turning around, the people who came were really the ones they guessed, the eldest grandson Wuji was in the center, slightly back, and it was Fang Xuanling and Du Ruhui who walked around the eldest grandson Wuji, looking at it, it was the eldest grandson Wuji who was walking in the middle who spoke just now, and the two hands that had just finished applauding had not been put down at this time.

Li Jing snorted and walked up quickly, greeting the three old immortals with his mouth, and beckoning the people in the room to move the chairs for the three old immortals with his hands.

After the three of them sat down, Li Jing sat down casually and asked, "I don't know if the adults are in a hurry, what advice do you have when you come to the old man?" ”

The eldest grandson Wuji laughed and said: "Come to Lord Li, how dare you have any advice, there are really some things that need to be discussed with Lord Li, I don't know if I have disturbed Lord Li!" ”

Wang Ke would not participate in this kind of occasion, he just stayed by the side of the four people who drew the map, watching these people complete the map there.

I don't know what a few of them were talking about there, just after speaking, Wang Ke heard the eldest grandson Wuji calling himself, Wang Ke knew this because his words just now were heard by these old immortals, and now I want to ask myself about this matter, Wang Ke originally said that he didn't think about doing it at all, but now he was heard by these old immortals, and it was estimated that he didn't run away, so he had to beat the 'spirit' and walked over.

Looking at the eldest grandson Wuji with a look of hope, Wang Ke is really a little speechless now, he really doesn't know how to answer once the eldest grandson Wuji mentions this, Wang Ke really knows too well, drawing a map is a trivial matter, but how much work is involved in the preparation before drawing, it is unimaginable, let alone now. In the era when communications were not developed, even in later generations, satellite remote sensing technology was already used, and the drawing of maps was a very complicated matter, and it was impossible for people who did not participate in it to experience that kind of hardship.

If Wang Ke is only responsible for organizing the drawing work, Wang Ke will not feel that there is any problem, if this matter is asked to take charge of the overall work, then he is a hundred unwilling, how good he is living like this now, wandering around during the day, chatting with people he knows, drinking tea, going home at night with his wife and son, and living a small life. It's very moisturizing, if Wang Ke is allowed to take people to the field to collect data, Wang Ke will not go if he is really killed, how bitter it is, Wang Ke is not willing to suffer like that!

How did the eldest grandson Wuji know that in just a few steps, Wang Ke thought about the matter over and over again, and asked Wang Ke vigorously, what are the differences between these maps with different coverages, and what are the differences between the maps used in government affairs and those used by the army, and a series of questions were asked to Wang Ke.

When Wang Ke heard these questions, he could only roll his eyes, not that Wang Ke couldn't answer, but Wang Ke felt that it would take too long to explain all these questions clearly, and he couldn't explain them in a few simple sentences for a while, which really made him very embarrassed.

But as soon as the eldest grandson Wuji finished asking, several old immortals and Li Jing all looked at Wang Ke, and even Li Tao came to join in the fun, moved a chair and sat there, looking at Wang Ke with the same eyes as Li Jing and them, waiting for him to explain the question raised by the eldest grandson Wuji.

Wang Ke saw the current scene, and knew that it was impossible for him not to say it, even if he couldn't say it completely, he had to say something, so he had to sigh in his heart and speak: "First of all, let's distinguish the difference between civilian maps and military maps, the so-called civilian maps are administrative divisions, which only involve the division of government affairs, such as where is the border of my Datang, where is the jurisdiction of each province, where is the location of the state capital, the distribution of major towns, and the connection of roads between towns. These are the scope of the civilian map, and in addition to the above, the military map should also mark the garrison situation of each place, the number of each army, the distribution of military facilities, etc., so that when any event occurs, it can be mobilized in time. ”

Wang Ke said so much in one breath, he really couldn't support it, and hurriedly leaned on the desk next to him, wanting to wait for a breath of relief before continuing, but these people were listening to it with great enjoyment, and when they saw Wang Ke stop, they all urged Wang Ke to continue talking, and they didn't take into account that Wang Ke was now dry and tired.

Wang Ke ignored the urging of these people, and took a good break before continuing: "The civil map is divided into the national map and the map of each province, the so-called national map refers to the entire territory controlled by my Tang Dynasty, for this kind of map, many small place names will not appear, some can only be some famous or important places after all, such as the conventional ones, the location of the state government ya' will definitely have, which is also convenient for the imperial court to count and manage all the places under its rule." ”

"The map of each province is much more detailed than the national map, and this kind of map only depicts one piece of terrain, and the area under the jurisdiction of this province is drawn 'precisely', so that the governor of the province can familiarize himself with the situation of the province under his jurisdiction, and it is also conducive to the travel and business of officials and people. As for the map drawn by the state capital, it is no more so, but the area drawn is narrower and limited to the boundaries of the state capital. ”

Wang Ke finally finished this matter in the shortest words, as for whether these people understood, and how many questions he still had not answered, Wang Ke didn't think about it anymore, if he wanted him to say anything more, he didn't want to speak again, after saying so much, plus a few people who drew maps just now said a lot, Wang Ke began to feel that his throat was a little dry, and his voice had changed a little, he was really afraid that if he said this for a while, he would not even be able to speak.

None of the people present here still remember what questions Wang Ke didn't answer, and they were still recalling what Wang Ke said, for them, they didn't expect that there was so much knowledge in such a small map.

Now they all deeply feel that life is full of knowledge, if you want to understand the world, you don't just know how to read a few books, there are many things in life, you can't read in books, many things, in fact, come from life, as long as you observe carefully, you can actually learn a lot of things.

After thinking quietly for a long time, the eldest grandson Wuji took a breath and said: "Virtuous nephew, when this matter is done now, why should the old man recommend it to the emperor, let you also take care of government affairs, and let you only give advice to Lord Li and them. ”

The eldest grandson Wuji's words were originally not malicious, but when he heard Li Jing's ears, it was a little harsh, Li Jing was reluctant, and asked with a glaring eye: "You old horseman, what is the meaning of contributing to us is 'waste' the ingenuity of the kid, is it okay to contribute to you, isn't it right to contribute to us!" ”

The eldest grandson Wuji was stunned for a moment, and then he reacted, he said it casually, and he really didn't take Li Jing into account, and hurriedly apologized to Li Jing, and explained that he didn't mean anything else, but just had some sighs, and put Wang Ke standing aside and laughing secretly.
