Cheng Yaojin did not leave any military books in history for future generations to admire, but it does not mean that he knows nothing about the art of war, nor does it mean that he does not know how to command operations.

Under Li Shimin, it was not easy to get the title of Duke of the State.

"Is this sand table difficult to make?"

Cheng Yaojin leaned over the sand table, looking at the roads, houses, and hills inside, his expression constantly changing.

"My lord, although I did not make this sand table, as far as I know, it still takes some effort to make an accurate sand table, and not everyone can make it. For example, the positions of the roads on the sand table, the hills

The height of the artificial lake, the area of ​​the artificial lake, etc. To understand these accurately, at least you need to be a scholar who can read and write; to put it more bluntly, at present, some students of Guanshishan Academy will make this

Sand table.

Of course, if you just make a simple model, it would be easy. Just find a few craftsmen and make a rough model. It will look similar to the sandbox in front of you, but the accuracy of the things inside is completely different.

.”

Although Wang Fugui was not sure why Cheng Yaojin was so interested in this sand table, he still carefully told the information he knew.

"Yeah, this sand table looks very beautiful, but there's nothing special about it? Businessmen buying houses won't decide to buy a house in Jinbi Garden just because your sand table is so beautiful."

Cheng Chuliang has not yet realized what the significance of this sand table is.

"Hey, if I could have had a sandbox map of the terrain around the battlefield when I led the soldiers to conquer Song Jingang, Dou Jiande, and Wang Shichong, there would be no need to sacrifice so many warriors. Chu Liang, you are now in the Imperial Military of the Tang Dynasty

Studying the cavalry department in the academy, think about it, if Xue Yantuo and his gang cause trouble on the grassland again in the future, and the court asks you to lead troops on an expedition, what will be the biggest headache for you?"

Although his son is not so up to date, Cheng Yaojin would like to take this opportunity to remind him.

"How to find the enemy is the biggest problem in the vast grassland. Our soldiers of the Tang Dynasty are no worse than the Hu people in terms of equipment and courage. The only difference is that the terrain is not as familiar as others. They are often exhausted on the grassland, but they are

There is no way to produce any decent results. Those barbarians took advantage of the favorable location to attack us. If they succeeded, they would expand the results. If they failed, they would flee quickly. Even if we win the battle, it will be difficult to annihilate them all."

Cheng Chuliang thought for a while and gave his own reply.

His answer can be regarded as the standard answer for most students in the cavalry department of the Military Academy.

Although the emergence of hot air balloons has made it easier for Datang's scouts to conduct reconnaissance than before, it is still difficult to accurately find the enemy and find a suitable ambush location.

"You are right. How to find the barbarians is the biggest difficulty. If there is a clear sand table map of the grassland, it will be easier to judge where they will gather. Combined with the use of the hot air balloon battalion, it will become easier to lock down the enemy.

; In addition, once the two armies are about to engage in a battle, how to arrange their troops and how to pursue and intercept them, in previous years this was a test of luck and the strength of the generals. However, if there is a sand table map around the battlefield, even a person who doesn't know much about it can

People who are skilled in the art of war can easily judge the most appropriate way to attack."

Cheng Yaojin suddenly felt that today's trip to the sales office was really worth it.

Just introduce this sandbox to the Royal Military Academy of the Tang Dynasty, let the students in the Staff Department study it carefully, and then start drawing sandbox maps of the major capitals of the Tang Dynasty. When a war breaks out, it will definitely be

A huge weapon.

"My lord, this is just a miniature of our golden garden. Is it of such great use?"

Wang Fugui on the side looked at Cheng Yaojin dumbfounded.

In his opinion, this sand table is useless, and Jinbi Garden has not become popular because of it.

Of course, sales have not been affected by the sand table.

"What do you, a businessman, know? Chu Liang, go to the Prince of Chu's Mansion now, say hello to Kuan'er, and ask him to take Liu Yuan to the Military Academy. Also, all the sandboxes in front of you will be moved to the Military Academy.

Remember, don’t break it, this sand table may still be the treasure of our military academy in the future.”

Cheng Yaojin didn't care whether Wang Fugui agreed or not, so he had to move the sand table in front of him first.

The actual person in charge of the military academy is Qin Qiong. As long as he sees the sand table in front of him, he will naturally understand its benefits; so Cheng Yaojin is not worried at all that no one will support his decision.

"My lord, this...isn't this appropriate? Our Jinbi Garden has just started to be sold. This sand table can give customers a clear understanding of the location of the house they bought. You can move it away like this.

There is no way I can do anything for the prince."

Wang Fugui's face turned green when he saw that Cheng Yaojin had asked someone to dismantle the large sand table in the center of the sales office without saying a word.

If Cheng Yaojin hadn't been Li Kuan's father-in-law, he would have cursed.

"Kuan'er, I will tell you of course! Just arrange for someone to help with the relocation immediately!"

Cheng Yaojin ignored Wang Fugui's protest and asked him to help with the relocation.

…

"My boss, have you heard? Li Kuan is so prodigal that Cheng Yaojin couldn't stand it any longer, so he took his son to the sales office to try to make trouble!"

In the Yang Mansion, Yang Dong came to Yang Benman with a gossipy face.

During this period, Yang Benman asked Yang Dong to arrange for personnel to keep an eye on the activities of the sales office in Workshop City at all times, so he naturally found out about Cheng Yaojin's visit to the sales office today.

Not long after Cheng Yaojin entered the sales office, he forced people to move the sand table away from inside.

Anyone who has been to the sales office will have some impression of the sand table.

So I don’t know who started it, but the story spread that Cheng Yaojin went to the sales office to cause trouble.

That night, everyone in Chang'an City who should know knew the rumor.

"I think this matter is mostly based on rumors. But if Workshop City is really a bottomless pit, it is possible that Duke Lu will intervene. But the current situation has not reached that level yet."

Yang Benman was confused by the current news.

"Who knows. I heard that Mr. Lu, even in the court, would get into fights if he disagreed with others. He was very hot-tempered and would go directly to the sales office to cause trouble. It is also possible."

Yang Dong's understanding of Cheng Yaojin was obviously still very superficial.

However, this is really the impression Cheng Yaojin hopes to leave everyone.
