I am not an ant thief in the Three Kingdoms

Chapter 108, Sand Table

Just when Xu Wei was thinking about the Modao army.

Wang Lei continued: "Fortunately, we have been building the Great Wall and Wubao on the border. As long as we guard a few conspicuous places, it will be difficult for the Xianbei to invade our Mayi!"

After Xu Wei came to Mayi, in order to strengthen the defense, Wubao was built in the gaps of Datong Basin such as Wuzhou, Qiangyin, Pingcheng, and Nao County. It is not the Wubao of this world, but the strongest defense in the cold weapon era. The diamond-shaped docks, especially Xu Wei, also used earth cement. Each diamond-shaped dock can accommodate 2000 people. In terms of defense, in addition to being besieged until the supplies of these docks are exhausted, 2 to 3 people will die People, there is no other way to break these docks.

Niu Gui shook his head and said: "Although the terrain of Mayi is considered dangerous, there are many gaps that can be broken through. For example, Pingcheng County is the first line of defense to guard the northern fortress. But it is not as dangerous as Yanmen Pass, which only guards the dock Fort defense is very difficult to defend the hundreds of thousands of Xianbei cavalry.

Hundreds of years ago, Emperor Gaozu personally led the army to the north to meet the attack. He was victorious in successive battles, so he underestimated the enemy.Think about it and know that a battlefield that can accommodate hundreds of thousands of people is very difficult to defend.The Xianbei people came to plunder, and they would bypass Wupu if they couldn't take it down, but we couldn't let the Xianbei people get close to Mayi. After all, our workshops are all on the Sanggan River outside Mayi. "

Niu Gui often travels around and knows the terrain around Mayi very well.

The reason why the Han Dynasty gave up the land other than Yanmen Pass was due to the fact that its strength was declining and it was difficult to defend against the continuous invasion of the Xianbei. In addition, the terrain outside Yanmen Pass was not considered dangerous, and it would take a lot of military power to defend it. Therefore, as soon as Xu Wei occupied Mayi, The big man simply gave up all the land outside Yanmen Pass.

And Niu Gui had never seen the power of a diamond-shaped fort, and he only calculated it as the defensive power of a general fort in the Han territory. Naturally, he felt that it was difficult to defend against the attack of the Xianbei with a fort of more than 2000 people.

"Do you have a map?" Xu Wei wanted to check the terrain around Mayi to see where it could be defended!

Soon there was a soldier with a map spread out on the table in the conference room.

But this map is very simple, only a few lines represent rivers, a small hill represents mountains, and squares represent cities and fortresses. Xu Wei basically looks pretty good!
"Should have made the sand table sooner!" Xu Wei patted himself on the forehead in regret!
It's not that Xu Wei doesn't pay attention to the sand table, but that the foundation of this world is too little, and everything is really lacking. He can only think of something and "invent" something. After coming to Mayi, most of his world is in the When engaged in production, they also produce things such as blast furnaces, textile machines, and cement. Naturally, they did not think of sand tables as a weapon in the military.

"Sand table?" Wang Lei and the others were all baffled, they didn't know what this sand table was!
Xu Wei can only explain: "Hundreds of years ago, Fubo General Ma Yuan helped Emperor Guangwu revive the Han Dynasty, quell the chaos of the Qiang, and settle the Lingnan. At the beginning, he quelled the chaos, in order for Emperor Guangwu to see it easily. To understand the topography and geography of Xiliang is to pile rice into a mountain and create a sand table of the topography of Xiliang!"

This is the prototype of the initial sand table.

The sand table is a pioneering work in the history of war and is of great significance.Of course, such a pioneering thing of great military significance was lost in later generations. Even though it was recorded in history books, no famous general restored the sand table. It was not until the rise of the West that the modern sand table appeared.

I don't know if this counts as a defect of "good reading without seeking deep understanding". There are many good things in Huaxia hidden in the history books like this.But no one has recreated it. Of course, this is also because they don't know the efficacy of these things!

Although Xu Wei explained to Wang Lei and the others, they still peeked at each other. Emperor Guangwu and the others knew, but who was General Fubo Ma Yuan?They don't know.

Wang Lei and the others also followed Xu Wei to learn characters for a year, and barely knew hundreds of characters and simple arithmetic operations, but it was a bit embarrassing for them to know historical allusions.

"It turned out to be the allusion that General Fubo Ma Yuan piled rice into a mountain!" Zhang Baiqi, who attended the Ma Yuan high-level meeting for the first time, suddenly realized.

At any rate, he is familiar with the Six Classics and history books, so he is naturally not as illiterate as Wang Lei and the others!Even General Fubo Ma Yuan didn't know who it was.

Seeing Wang Lei and the others in a daze, Zhang Baiqi explained: "The so-called pile of rice as a mountain refers to the ancestor emperor Liu Xiu of this dynasty who personally conquered Kuihuo. Going deep into the dangerous obstacles, Liu Xiu also hesitated and couldn't make up his mind.

But at this time, General Fubo Ma Yuan was ordered to come. After learning about this, he tried his best to persuade Emperor Shizu to continue marching to wipe out Kai Xiao, and ordered people to fetch rice and arrange it into valleys and ravines. The situation of mountains and rivers marks the roads for the advance and retreat of various troops.

In the end, Emperor Shizu defeated Kaihuo with the help of General Fubo and unified the world. Only then did the 200-year national fortune of this dynasty come into being. "

After Zhang Baiqi's explanation, everyone suddenly realized that rice was used to make maps.

But Zhang Baiqi asked curiously: "Shuai Lei, General Fubo's drawing method has been lost for nearly 200 years. You really know how to make this kind of map?"

Xu Wei said: "The method is not difficult. It is recorded in the history books. We can do it according to the history books. And it doesn't have to use rice. It can be made with sand, but it will take a little time."

Xu Wei had heard of it, but hadn't made it. He planned to find a skilled craftsman in Mayi to make a sand table after the meeting was over.

After talking about the sand table, Xu Wei said to Niu Gui: "If you find a way to find out about Helian's movements, you must know how many people they gathered, the target and time of their attack!"

Niu Gui said seriously: "No!"

Niu Gui is now in charge of the entire caravan in Mayi. It can be said that the grasslands around Mayi are covered with Niu Gui's footprints. Because the business is fair, he will find ways to help the Hu people when they encounter difficulties, so Niu Gui is in Hu Among the people there is a title of Timely Rain, and his Huren friends are all over the world, and there is no news on the prairie that he can't hear.

"Wang Lei, go and gather the barbarians around us to form the righteous cavalry. Now it's time for them to contribute!"

Wang Lei said happily: "No!"

There are tens of thousands of Hu people in Mayi, and 3 to 4 cavalry can be formed. The large cavalry unit he wanted can finally be realized.

Seeing that all the high-level officials present were assigned tasks, except for the generals of the Yellow Turban Army, Zhang Baiqi said, "Now we are also a member of the Tengjia Army. Commander Qu can't favor one over another, let us just watch?"

　The protagonist is Xu Wei, according to the habits of this era, there must be characters, readers who know how to read characters, please help me think of one
