Chapter 623 Li Shimin saw the map, he was very happy, how to look at it and how he liked it, he was very clear about the value of such a map, so he kept staring at the map.

"Hey, you like it, right?" Qin Huaidao saw Li Shimin staring at the map like this, and said with a smug smile.

"Like, for my father?" Li Shimin immediately looked up at Li Shimin and asked.

"Of course, for you, what do I want? Now there is no way, there are too few people who can do arithmetic, if there are more, the son will map the whole country for you, let my father see, how big the world is, how many mountains and rivers in the world are! Qin Huaidao nodded affirmatively and said happily.

"Well, good, good, my father likes this, likes, that, the whole country also measures, if you don't know how to do arithmetic, you can cultivate, isn't it that no one likes snow and arithmetic?

You are like this, all the people who participated in the drawing of the map this time were incorporated into the Ministry of Industry and became officials of the Ministry of Industry, well, it was set at the eighth grade, in this case, my father didn't believe that no one would learn, could it be successful? Li Shimin looked at Qin Huaidao and asked. Qin Huaidao looked at Li Shimin in surprise.

"If it doesn't work out, don't stare at your father!" Li Shimin said to Qin Huaidao.

"That's definitely it, if that's the case, then there must be a lot of people who learn this Gewu and arithmetic, father, you are too wise!" Qin Huaidao stood up happily and gave Li Shimin a thumbs up.

"Stinky boy, sit down and say, make tea for your father, good boy, silently, just give your father such a gift, well, okay, my father is happy, by the way, what is this?" Li Shimin followed the telescope on the chair next to Qin Huaidao and asked Qin Huaidao.

"Hehe, you must like it, Father!" Qin Huaidao stood up with a telescope as he spoke, and said to Li Shimin at the same time: "Father, you come!" ”

Li Shimin didn't know what Qin Huaidao was going to do, so he walked over, Qin Huaidao took Li Shimin to the window, looked outside with a telescope, and then handed it to Li Shimin.

"Look at the guards on the other side of the square, it's really hard, it's sweaty!" Qin Huaidao said and handed it to Li Shimin.

"What do you think?" Li Shimin took it puzzled and asked Qin Huaidao.

"Just put it in your eyes and look at it!" Qin Huaidao stared at Li Shimin and said, Li Shimin immediately put it on, and then took it down in an instant, and then put it on again, and then took it down.

"This, this, this? How can it be? Li Shimin looked at Qin Huaidao in shock and said.

"Father, this is called a telescope, which we need to use in this surveying and mapping, but Erchen thinks that this is also very helpful in military affairs, for example, our scouts need to observe the enemy's military situation, so there is no need to get so close, and you can see the situation on the enemy's side from a distance, don't you say?" Qin Huaidao looked at Li Shimin with a smile and asked.

"Hmm. Well! Li Shimin nodded, took the telescope and looked there.

"These boys are lazy, Cheng Chuhei, this kid is actually hiding under a tree and holding a grass, bragging!" Li Shimin looked outside with a telescope and said to Qin Huaidao.

"Where?" Qin Huaidao couldn't see it, so he asked.

"That!" Li Shimin pointed to the distance and said, Qin Huaidao looked over and couldn't see it clearly. Then Li Shimin put down the binoculars and couldn't see it at all!

"Good things, good things, it is estimated that the soldiers on the front line have this, and we can all take the lead in fighting the enemy!" Li Shimin said and looked at the binoculars again.

"Hehe, it's useful, Erchen knows it's useful, so I'll send it to you." Qin Huaidao said to Li Shimin with a smile.

"Hmm. Useful, useful! Very useful! Li Shimin stood there, nodded frequently and said.

"Let's go, drink tea, hurry up and make tea, how did you make this tea, and there is no tea coming out until now?" Li Shimin asked Qin Huaidao with a smile.

"Didn't Erchen explain it to you? Soak now! Qin Huaidao smiled and walked to the side of the tea room and said.

"Coming, coming, the pharmacist is here, and Zhang Liang, Li Daliang, and Tang Jian are all here, well, by the way, come on, go and call Gao Ming to come over!" Li Shimin turned his head to look at Wang En beside him and said, Wang En smiled and nodded, and soon went out!

"Look at them, it's not hot, you need to add some ice cubes later, otherwise, it's too hot, look at the sweat of Zhang Liang's head!" Li Shimin was still there watching with a telescope,

Qin Huaidao was smiling and making tea there, and after a while, Wang En came in to report that they had arrived, and Li Shimin returned to his seat with a smile.

"The minister has seen Your Majesty!" After Li Daliang and the others came in, he saluted Li Shimin and said.

"Come on! Sit down, today I have obtained two treasures, which were given to me by Pepin, come, look, pharmacist, you look at this first! Li Shimin gave Li Jing the map of Chang'an City as he spoke, and Li Jing took it, first gasped, and then looked at it carefully.

"This, this, who drew the map, who?" Li Jing looked at Li Shimin in shock and asked.

"Is it good, precise or not?" Li Shimin looked at Li Jing proudly and asked.

"The directions are all right, what does this 500 meters mean by 1 centimeter?" Li Jing looked at the words under the map and asked.

"Yes, it's a mile like this, I don't understand it, I understand it!" Li Shimin said to Li Jing, Qin Huaidao also said something similar just now, 500 meters is almost a mile.

"This, I'll see!" Li Jing began to look for it on the map as he spoke, and Zhang Liang and the others also gathered around and watched, all of them were amazed.

"Accurate, accurate, basically about the same, the direction is right, in addition, the direction of the Wei River is also right, you look at this bend, that's it, and the next few villages are also right!" Li Daliang also said in surprise.

"Pepin's dedication to His Majesty, then, Pepin, who drew this map?" Li Jing stared at Qin Huaidao and asked, and the others also stared at Qin Huaidao and asked.

"Who else could it be but him? Before, Peping took students to measure the streets of Chang'an City, didn't you see it? Li Shimin said with a smile.

"Is it really you?" Li Jing stared at Qin Huaidao and asked.

"yes, didn't we talk about the map last time? My nephew thought, since I don't have it, then my nephew will come and get a pair, anyway, I think that the map you gave me before my uncle was drawn by yourself, and I am accurate, and all the locations are accurately measured.

In addition, there is a picture below, that map is more useful, that is, the topographic map, you look at the circles below, a circle is a difference of 7 battles, in this way, where the terrain is flat, where the terrain is dangerous, at a glance! Qin Huaidao said, pointing to another map.

"This, this, Your Majesty, such a map is very helpful for our military operations, very helpful!" Understanding looked at the two maps and said excitedly to Li Shimin.

"I know, didn't I call you over? There's something better, come, come, I'll show you, what clairvoyance is! Li Shimin proudly shouted to them to come to the window, while Qin Huaidao smiled and made tea there and distributed tea to them.

Then Qin Huaidao heard the exclamations of the old men there, and then rushed to use this telescope, no one was drinking tea at all, they were all discussing, Cheng Zhiji was leaning against the root of the tree there, holding a piece of grass, he never dreamed that he was lying here to rest, and he actually became the object of those people's comments.

"This kid is a little lazy, look at this look, it's the same as when his father was lazy!" Li Jing looked at Cheng Chuhei with a telescope and commented.

"Sort of!" Li Shimin also nodded.

"Show me, this is a good thing, if there was this thing in the war, how many ambushes would we have missed?" Tang Jian immediately snatched it and continued to watch there, Qin Huaidao was drinking tea there alone,

After a while, Li Chengqian came, and followed to watch, and then with them, like a group of children who had gotten a novel toy, and for about a quarter of an hour, they began to return to the tea table one after another.

"Good boy, you have the ability, just let you go to the military department, look, these two things are very helpful to the army, needless to say the map, just now Your Majesty said, now your people are still measuring, right?" Li Jing touched his beard, looked at Qin Huaidao and asked.

"Well, it's to measure the terrain from Chang'an to Luoyang!" Qin Huaidao nodded with a smile and said.

"Your Majesty said that it should be attributed to the Ministry of Industry, I don't think it is appropriate, I think, it should be attributed to the Ministry of War, after all, this map can only be obtained by people from other countries, so that the Ministry of War can ensure that those maps will not be lost!" Li Daliang thought about it for a moment and spoke.

"Also, this is something I didn't think about enough!" Li Shimin nodded and spoke.

"Well, it's okay, it can be attributed to the Ministry of War, in fact, you can set up a surveying and mapping department, let them go to surveying and mapping, and find out the great rivers and mountains of my Datang." Qin Huaidao nodded and agreed to do so.

"Okay, that's it, this department will be handed over to Peping to manage, how, in terms of personnel, how many people do you think are needed?" Li Shimin asked Qin Huaidao.

"It may take hundreds of people, and besides, father, if you want to fight Goryeo, the sons hope to be able to secretly send them to Goryeo to investigate, but they are all students, not soldiers, and they still need soldiers to protect them!" Qin Huaidao thought for a moment and said to Li Shimin,

As soon as Li Shimin heard this, he understood that these people not only wanted to survey and map the terrain of China, but also the terrain of other countries.

"Well, recruitment, you can recruit as many people as you say, in addition, on the Goryeo side, if you need to send it, you can get a charter when the time comes, pay attention to keep it secret!" Li Shimin thought about it for a while and spoke.
