For Li Chengqian, the conspiracy is just a process, and he has a way to stop it in advance!

And now he has something more important.

It is not an easy task to build a hundred banks.

This has to be considered in the long run.

On this day, Li Chengqian asked all the personnel of the six departments to be present, plus Ma Zhou, Fang Xuanling, Du Ruhui and others were also on the spot.

He said: "Ma Zhou, are there any statistical needs in the states and counties of Datang? ”

"Your Royal Highness the Prince, according to the statistics of the ministers at this time, there are about more than 200 regions that need banks, and the ministers are also required to decide which one needs it the most."

There are more than 200 locations, and how difficult it is to remember them all.

These places are all literal place names, and no one can say for sure what is spatially.

"Really? Come on, pull out the sand table for this king! ”

Sandbox?

It is a model made of sediment, flags and other materials according to topographic maps, aerial photographs or on-site terrain in a certain proportional relationship.

In military-themed movies and television works, we often see commanders standing in front of a terrain model to study the battle plan. This kind of model, which is based on topographic maps, aerial photographs or on-the-ground terrain, and in a certain proportional relationship, is made of sediment, flags and other materials

The sand table has the characteristics of strong three-dimensional sense, intuitive image, easy production, economy and practicality.

This kind of thing is simply a novelty in front of the ancients.

Gao Shilian asked, "His Royal Highness the Crown Prince is ......?"

"Just look at it!"

After a while, a sand table of nearly ten square meters was pushed out.

It is marked with the names of large and small states and counties in the Tang Dynasty.

When this sand table appeared, everyone was amazed.

Someone else said.

It's a living map!

No, all the mountains and rivers, as well as the residential areas and topographic maps are outlined.

Du Ruhui asked:

"His Royal Highness the Prince, this is the territory of the Tang Dynasty?"

"That is, this is a big sand table that this king asked people to create, and we use this sand table to determine the location of the bank, and we will be able to achieve as much balance as possible, and we will not favor one over the other."

Li Chengqian would not tell them that he had made this map from a book, and that it was all the result of making it from memory.

In his mind, all knowledge is memorized, and all maps are also in his mind.

"That's amazing!"

Everyone has already looked around the sand table several times.

It's as fun as an adult's toy.

"Ma Zhou, you have planted the names of those 200 or so with yellow flags, and we will re-determine the location of the bank according to the location on it."

The position of the bank is very important, and if it is not opened well, then it will lose its meaning. If you can't make money, you will also post it upside down, and Li Chengqian will not do this kind of thing that does not outweigh the losses.

Ma Zhou should have planted the yellow flag according to Li Chengqian's intentions, and after a while, a sand table full of yellow flags appeared in front of everyone.

Sun Qian said: "In this way, it is really clear at a glance! ”

"That's a lot better."

Next, Li Chengqian picked up the red flag and said.

"Here are a hundred small red flags, from here the king will ...... Here, and here...... Start replacing the yellow flag ......"

Li Chengqian began to replace the yellow flags on it with red flags, and after a while, what appeared on the entire sand table was a topographic map of the bank's location.

"Ma Zhou, write down these points, and a hundred bank locations are them!"

"It's good, it's really good!"

The horse said in praise.

There may be no better existence than Li Chengqian's method.

"Yes, this method can save a lot of time, manpower and material resources."

Duan Lun also said.

And Li Jing asked: "I just don't know if this sand table is accurate?" ”

Li Chengqian smiled.

"Yes, absolutely! This sand table can not only be used for decoration, but can even be used for operational command. You can also wait and see the great rivers and mountains of my Tang Dynasty! ”

What could be more intuitive than looking at the sand table?

As soon as Li Chengqian's words fell, he heard someone laughing outside.

"What can see the great rivers and mountains of my Tang Dynasty?"

Listening to this voice, it is Li Shimin.

How did he get here?

Probably because the palace is bored again, during this period of time, Li Shimin has always been running around, or because there is one less eldest grandson queen by his side, there is one less person to talk to.

And they saluted.

"Meet Your Majesty!"

"Excuse me! When I was outside, I heard what you were saying, great rivers and mountains? ”

It turned out that Li Shimin came in when he heard this sentence.

Du Ruhui said before Li Chengqian: "It was His Royal Highness the Crown Prince who created this thing called a sand table. ”

"Oh? Sandbox? ”

Li Shimin stepped forward to take a look and paused for a while.

He was also stunned by what he saw.

"This is Chang'an? This is the area east of the Guanzhong River? This is the merger and Fen that I have recovered! ”

He seemed to remember the past.

On this sand table of less than ten square meters, Li Shimin paused for a long time.

Then he added: "The terrain is so vivid. Gao Ming, how did you come up with the idea? ”

"Your Majesty, Erchen also discovered by chance that if the map is topographed, it must be the best effect, and this kind of topographic map has an innate advantage for fighting a war, and we can take advantage of the situation and make full use of the terrain to fight."

"Good, good, good! If this sand table is put into battle, it will definitely be able to achieve better combat results! ”

No one understands better than Li Shimin the operational significance of this method.

When Li Shimin was not the emperor, he fought in the south and the north, and most of the Tang Dynasty was defeated by him.

His combat experience is also unprecedented.

He is not wrong, of course, this is not only applicable in ancient times, but also has a very important role in modern times.

"Your Majesty is wise!"

How could Li Chengqian not know everything Li Shimin said?

But he is still wise.

"Gao Ming, you've been a great help. This has to be carried out well. ”

"Yes! Your Majesty, the sons and daughters also did not intend to do it. ”

Li Chengqian pretended to be forced once, which caused everyone's mood to change very much.

At the same time, he also gained thousands of points.

"Gao Ming, have these 100 banks ever set a location?"

Li Shimin asked again.

"It's decided, and it's determined by the position of the sand table. Your Majesty, please see. ”

Li Shimin looked at it for a while and said: "The interval between these positions is very reasonable, and it seems that this time the hundred banks will be of great use!" ”

"Yes, Your Majesty, this is also the result of the cooperation between the sons and the ministers."

Although Li Chengqian did all this, he didn't have any merit, because there was no need, so he simply said that everyone had a share.

Let everyone be grateful.

"I'm glad I got you."

Li Shimin nodded and said.

Suddenly, a discordant voice came.

"Report! …… There is something important to repay. ”
