"I don't have any gifts and I'll get up, hahaha, I'll discuss this matter tomorrow. By the way, my son-in-law, why are you here to find me?"

"The son-in-law is here, for the portrait of his father-in-law, and the other is, my nephew hears the words. I have a good object like a sand table in the court. I am really curious and want to come and observe it." I dare not finish all the words, so I dare not mention the matter of entering the Juyuan. As for the matter of the map, I can't code it correctly. I will discuss it with Uncle Li when there is no one.

"Sand table?" Uncle Li blinked and smiled, "That thing is there, but a wise son-in-law, what's the use of that thing? There is no need to fight now."

"Ah?!" Damn, it's a temporary sand table? I'm so damn, who are they? Such a very military value is really impossible to express my mood from excitement to loss in words.

"I am a little exhausted. Your Majesty, I will take my leave first." Uncle Li Jing was a little pale when he heard the sand table. He wanted to escape at the last minute. He glanced at the left and right. The two court bosses all had a bitter face. Whatever he did, wasn't it just a sand table?

"Don't worry, haha, since the son-in-law asked, let's go with me, let's go and have a look. You all come together. After looking at the sand table, it's not too late for you to leave." Uncle Li was very excited and led our troops out of the door.

"Father." When the old man walked beside me, he deliberately coughed dryly and quickly lowered his head to express his respect.

The old man glanced left and right, lowered his voice and said quickly: "Well done! I am worthy of being a descendant of my Fang family. I am upright and dared to speak out. I am very comforted, haha..." The old man was very excited and felt like he was walking in the clouds when he walked.

"Son-in-law comes here, your words were flashing just now. Could it be that there is nothing difficult to say?" Uncle Li slowly walked towards the other direction with a group of court bosses, as if he remembered something and turned towards me and asked.

"My father-in-law. Why don't I have a complete and complete map of the Tang Dynasty?" Xiao trotted to Uncle Li and stood attentively and asked earnestly.

"Do you know how difficult it is to make a map? It was not our dynasty, the previous dynasty, and the previous dynasty, which was not dedicated to drawing the territory of China, but it was impossible to draw it. It took so much manpower and material resources." Uncle Li sighed while walking.

"Oh..." While walking, he flattered Uncle Li. It took him a long time to reach another hall. When he entered the hall gate, Uncle Li led us to a corner, where there was a table about the size of a ping-pong table. There were several pieces of yellow mud on the table, like a little kid playing with a pile of sand.

Uncle Li was very proud and pointed his hand at the golden cake that looked like the third child in my house at the doorstep and said, "This sand table was built by me personally. I see this. This is the Helan Mountains, this is Yin Mountains, this is Taiyuan, this is Yunzhong. And this is Baidao. In the fourth year of Zhenguan, Li Jing went out of Yunzhong and fought fiercely with the Turks in Baidao. He defeated the Turks, and then rushed forward and defeated Jie Li Khan again at Yinshan. Haha... Jie Li fled north and sent Zhi Shi Si to see me, asking for his support. I was benevolent and approved what he asked, but he pretended to surrender and wanted to restore his strength to flee to the north of the desert. Fortunately, these two beloved ministers met with Yu Baidao, and they discussed it in two sides to find out Jie Li's motives. The two ministers immediately attacked at night..."

The eyes of the imperial chiefs were dull and they responded for a long time. It seemed that Uncle Li had shown up for many times. No wonder these old guys were going to see the sand table when they heard that they were distorted...

I understand Uncle Li's words very well. But the problem is that his hands always gestured between the lump and the lump. I didn't know which lump was, and it was difficult to belittle Uncle Li's sand table making level, so I had to silly show my respect for Uncle Li. This old man is really good at bragging. It seems that the Li Tang Dynasty was famous because of this battle and defeated the Turks. The chiefs of all tribes in all tribes were afraid of the force of the Tang army, and they all ran to Chang'an to ask Uncle Li to call him "Tian Khan". They flattered and expressed their submission. You are embarrassed to cut our heads with a knife, right? So Uncle Li proudly praised the title of Tian Khan. After that, the seals given to the chiefs of all tribes in the northwest were all called "Tian Khan"-

"The interests are good and bad, and my father-in-law is really good and bad." He was perfunctory, and he really didn't want to see the sand table piled up like a compost. It was hard to see people when he said it.

"Son-in-law," Uncle Li brags for a long time, as if he saw my expression a little wrong with the plate. He coughs twice, "Is this sand table not enough?"

"No, this," I don't know what to say, it's shameful. If you take such a sand table in future generations, you can laugh at the dogs.

"Well, what do you mean?" Uncle Li seemed to be dissatisfied with my expression and answer, and said to the corner of his mouth.

"This," gestured with his hands: "I think it's too simple."

"Well? The son-in-law said something, don't be too rude, it will make me unhappy." Uncle Li was a little impatient.

"The son-in-law just thinks that the accuracy of the current sand table seems to be slightly lacking. The use of sand tables in war is to be able to understand the form of both sides on the battlefield at a glance, and provide commanders with three-dimensional, vivid and intuitive information, so as to facilitate military commanders to use as a deduction tool for combat resource arrangement, planning, decision-making, command and execution.

If our Tang Dynasty wanted to establish a general staff, this item would be a top priority. It would be of great significance to allow all military personnel in the rear to accurately understand the battle situation and strategic deployment. Moreover, if a military academy was established, although our Tang Dynasty military practitioners could not face the battlefield directly, they could use accurate sand tables to deduce the warfare cases that had occurred and enhance their military command capabilities. Confrontation training on the sand table would play an extremely important role in improving the combat capabilities of the army and promoting the development of military theory..." Walking in a square step, walking to the sand table, stretching out a finger to pinch it. It is not the kind of yellow mud that is extremely sticky, but should belong to the yellow sand that is easy to shape.

My mouth was very dry, I have been talking for a long time? Uncle Li and others sat on the stool at no time, like students who were interested in learning, staring at me. When I finished speaking, Uncle Li and other military personnel were very lit their heads with great agreement. Very good, they are worthy of being a senior military commander who has been through the battlefield for a long time. They can help them with a dry cough and continue to show off: "Sand table is not only a wartime need, but we can also conduct sand table drills on other matters... This is not only a military need, such as the Ministry of Works to build cities, maintain cities, and also the maintenance and construction of various major traffic arteries in our Tang Dynasty. Similarly, there is this sand table, which part and that building will be rectified or built..."

"Oh? Can the sand table be used for this?" Changsun Yin stepped out, looked at the lumps, and asked curiously with his fingers.

"That's right." I vomited out all the importance and necessity of the sand table for military education and military staff.

"The words of my nephew are indeed great. I just don't know how to build this sand tray as three-dimensional, vivid and intuitive as you said? I want to see it." Li Jing, the first person in the Tang Dynasty military, stood in front of me and asked.

"This, my nephew is just a shame. A few days ago, I arrived outside the city and remember some of the terrain." I rolled up my sleeves and bowed to Li Jing and the big guys, walked to the pile of yellow mud and sand, stirred it with my hands, and all the big lumps disappeared. "Give it water!" I will build a cannon tower today to open my eyes to Uncle Li.

"Get some leaves outside, and the smaller the better. Take a few thin pieces." He said to the eunuch who was standing beside the silly.

"You are following my son-in-law's orders, why don't you go quickly? I didn't expect my nephew to play with this?" Uncle Li was very enthusiastic, and the big guys were also very curious. They seemed to have a special hobby for playing with mud. They stared at the boss and watched the yellow mudsha take shape under my push and slapped. "Hehe, it's nothing. I often played when I was a child."

"Oh?" Uncle Li and others looked at my old man with their eyes. The old man was very modest: "This child always liked to play with mud when he was young, building some castles, mountains and rivers. I don't know how many times I have scolded him. This evil son is just disobedient and often wrapped like a mud monkey." He cursed, his eyes narrowed almost into a slit, and he showed off his appearance-

At the corner of the sand table, a city of adobe was built. In the middle of the plate, four fingers plucked hard, and the Wei River appeared, and then plucked it again, and the Ba River appeared on the other side. They took the leaves and then pulled it into the thin strips, and inserted them on both sides of the river. They bite the wooden board with their teeth, buckled, and bit off a small piece. They put it on the Ba River, and the Ba Bridge was also formed.

A group of old guys were stunned. Not very good at kung fu. A terrain map of the north of Chang'an City, which was exquisite than the sand table built by Uncle Li just now, appeared.

"Please look at this, this is Chang'an City. The raised area here is the imperial city, this is the Ba River, this is the Ba Bridge, this is the Wei River, and this is here..." I pointed out the places I went to one by one. Of course, the places I hadn't been to can only be blank. After all, it is impossible to imagine them out of thin air.
