Hearing the whispers of Li Yuanba and Niu Jinda, Cheng Yanjin suddenly came to his senses.

He quietly moved two more steps in the direction of Li Yuanba and the two of them, and then whispered: "Lord Wang, I know that in the ancient books of the Cui family, it was recorded that in the eighth year of Han Jianwu, when Emperor Guangwu conquered Tianshui and Wudu, the general Ma Yuan 'gathered rice for the valley and fingered the shape shì', so that Emperor Guangwu suddenly had the feeling of 'being captured in my eyes'. ”

Li Yuanba looked at Cheng Yanjin, who suddenly interjected, with some surprise, and said, "Zhijie, you have a lot of knowledge?" ”

"Hehe...... Cheng Yanjin touched the back of his head and said, "I, I'm all listening to the pharmacist!" ”

Burst!

Li Yuanba almost spurted out a mouthful of old blood, I said how could I say it so slipperily, and there was no pause, the relationship is now learning and selling!

After slowing down for a long time, Li Yuanba rolled his eyes and said, "Is the sand table just in the military department?" ”

"That's right, but this thing is very easy to get, just now His Majesty said to let the military department prepare the sand table, but in fact, it is just to let the people of the military department rearrange one in the side hall! It's only half a pillar of incense in terms of time! ”

Cheng Yanjin dug his nostrils very ungracefully, and he didn't care about it.

≥ Li Yuanba was completely messy after listening to Cheng Yanjin's words, he had never heard of the time to arrange a sand table with only half a pillar of incense, in such a short time, I am afraid that those mountains and rivers alone will not be able to get out.

When he was talking about this, a young general wearing armor, a horizontal knife at his waist and hips, and a fully armed young general hurriedly walked in, clasped his fists and saluted Li Shimin: "Your Majesty, the sand table has been arranged in the side hall, please move your Majesty!" ”

"Let's go with me! After looking at the sand table, Qing and others will think about countermeasures! ”

While speaking, Li Shimin strode towards the side hall, behind him. It is Li Yuanba and a large number of other princes and the ministers of the Tang Dynasty.

……

A large number of people followed Li Shimin into the side hall.

When I entered the side hall, I didn't see anything else, but in the small corner near the west window, there was a table with a billiard table and laughing, and the prince was already covered with dirt, like the soil of the beach by the sea.

"Brother Huang, where is the sand table?" Li Yuanba turned his head around and asked deliberately.

Sure enough, I saw Li Shimin stretch out his hand and pointed to the small platform near the west window. "That's, it's there!" ”

Li Yuanba walked around the little prince with excitement, and as soon as he glanced at it, he was completely stupid.

I saw that what appeared in front of Li Yuanba was a mixed soil that seemed to be composed of plateau soil and beach soil, and these mixed soils were made into small mounds of soil, which were stacked on small platforms in a messy manner.

Between these small mounds of dirt, there are also twisting rivers that are only the thickness of the fingers of the little fingers.

robbed the tomb in Li Yuanba's previous life...... Cough. As a doctor of archaeology, when I saw this mess in front of me, I just felt that the whole person was not good.

Because, the sand table on the small table on this side. For Virgo Li Yuanba, it's really ...... Too awkward, too discordant. Harmonious, it's so imperfect!

saw the stunned expression on Li Yuanba's face, which seemed to be a little idiot. Li Shimin seemed to feel very proud, and he twisted a small straight silver stick from the edge of the platform. Pointing to the clods that looked like a two-year-old boy fiddling with at random, he said:

"Yuanba, this sand table is built by the people of the military department based on the map that took a full five years to draw! Yuanba, come and see, here the Hexi Corridor ...... Here is our Silk Road, here is the Helan Mountains, Taiyuan...... And here, here is the capital of our Tang Dynasty, Chang'an City......"

The humerus ministers of the Tang Dynasty were all glazed-eyed, and they were obviously no longer familiar with Li Shimin's set of rhetoric.

Li Shimin's words were very straightforward, and the speed of his speech was also very fast, but his little stick was on this small platform, and he kept waving and waving, which made Li Yuanba dizzy.

Li Chengqian and the others had never seen this sand table before, so they were also listening to their father's speech very seriously, but it was a pity that this 'horn' was like a cannon to explain, and these unlucky children were all confused.

I don't know how long it took, but when Li Yuanba finally began to doze off, Li Yuanba also stopped unsatisfied.

"Yuanba, what do you think of this sand table?" Li Shimin put away the small silver stick, and there was still a hint of pride in his voice.

Li Yuanba's hands were on the edge of the small platform, and he pondered for a long time, and suddenly asked, "Brother Huang, do you have a topographic map of my Tang Dynasty?" ”

Li Shimin was stunned for a moment and said, "Yes, naturally there is!" But, Yuanba, what do you want to do with the map? ”

"Brother Huang, this sand table seems to be a little ......" Li Yuanba gestured back and forth with his hands in the east, west, north, south, and middle, how to look at how awkward this small platform is.

"What?" Li Shimin asked.

"It's a little too rudimentary." Li Yuanba turned his head and looked at Li Shimin, and said very seriously.

"Simple?" Li Shimin's eyes turned into light bulbs, "Yuanba, how clear is this sand table?" Prefectures, counties, mountains, rivers, forests, and fields...... Which one is very clear, how can it be simple? ”

"Brother Huang's sand table is built according to my map of the Tang Dynasty, and at present, although our sand table is marked out in various states, counties, mountains, rivers, and forests, no one can understand it except for the people who make the sand table, and the people who often fiddle with the direction in the sand table! Therefore, the younger brother thinks that it is possible to separate all the things that represent the human geography of the Tang Dynasty on these sand tables, and then mark them, so that even people who have never seen the sand table can see at a glance where the place on the sand table is, just like looking at a map! ”

"Looking at the map?"

Li Shimin and the civil ministers and generals in the court all looked at each other, but Li Yuanba's idea was too advanced, how could this sand table be the same as the map?

"yes, it's just that this map is a little more specific and three-dimensional! Moreover, the mountains and rivers in the sand table are completely in accordance with the proportion of normal mountains and rivers, and they will be placed on the sand table after they have shrunk countless times! In other words, the role of this thing in the conquest is incomparably huge! ”

While saying this, Li Yuanba slowly walked to the sand table, and stretched out a hand, just like playing with the ground and mud when he was a child, reaching out to pinch the nearest mountain to him, and then stretching out his hands to re-widen a few rivers...... In short, all of them are changing for the better! (To be continued......)
