"Send an order to Li Liang. When Tang Qi reports again tomorrow, order him to tell Li Yongshou: We need to be on strict guard and don't be careless!"

"promise!"

Li Xiaoxian left without taking the order. Li Chengzhi thought for a moment, then asked his confidant to hold a candle and read the map on the wall.

The map was made by bleaching and sewing several pieces of cowhide, and then using lacquer ink to make the map. It was nearly ten feet in diameter and almost covered a wall. It was densely packed with large and small characters.

And this is only the map north of the Yangtze River.

This was drawn by Li Chengzhi himself, and even if there are some errors, they are not very big. What is commendable is that wherever the soldiers, scouts, Tangqi, and even the soldiers of the Western Navy set foot, Li Chengzhi will personally check afterward.

Not to mention where there is a mountain, where there is a river, where there is a city, even if it is a pond, a ditch, a village, or even a small tribe with less than a hundred tents, he will ask clearly, and he will know more about it.

It's clearly marked on the map.

With such a map in hand, the general can follow the map and get twice the result with half the effort, whether marching, stationing, or forming a formation...

Li Chengzhi looked at it for a while and passed his fingers across Dunhuang Town.

Li Song has already led his cavalry out, which is only a thousand miles away. It will take at most ten days for the troops to reach Dunhuang City.

Gengzhen's elite troops had all been defeated along with Yuan's birds at the shore of Juyan Lake, and all the people in the city were old and weak. Although there were many strong men left, with artillery in hand, it was not difficult for Li Song to attack the city.

At that time, there will be no worries. Even if Chao Yanzhen and Rou Ran collude, they will not be afraid of being attacked from both sides.

In addition, there are 240,000 to 50,000 registered Ding households in Xiliang Prefecture, and nearly 200,000 live in Dunhuang, with more than one million dan of grain being collected. Therefore, just the Ding households and grain storage in Dunhuang Town can make people

Li Chengzhi can wake up with laughter even in his dreams...

After thinking for a while, Li Chengzhi retracted his finger and pointed north of Juyan Lake.

This is a vast land of thousands of miles, with few mountains, no water, and almost no barriers. If you ride a fast horse, you can explore three to four hundred miles in one day. So even if Rouran wants to disappear, it is impossible to march quietly.

Unless Rouran makes a big detour, deliberately bypassing Daqi, and sends troops from the north road, first to Six Towns, and then either attacks the east flank of the West Sea, or enters the Pass and advances westward through Longshan Mountain.

But in this case, I am afraid that I will not have to walk more than five thousand miles. I have to go back and forth, but if I don’t have ten thousand miles, I still have to walk eight thousand miles.

According to the marching method of Rouran dragging his family and driving the cattle, the march on the road will take three to four months, and this is under the premise that the weather is good and there is no wind or rain.

Therefore, regardless of whether the imperial court can afford to wait, the Rouran people absolutely cannot afford it.

In this way, Rouran was unable to attack the rear route to the West Sea, and was unwilling to detour thousands of miles. Whenever he sent out troops, he would most likely arrange his chariots and horses to attack Juyan Lake.

If it were just Rouran, Li Chengzhi would naturally not be afraid. To be honest, in front of firearms, the half-civilized Hu cavalry was much easier to deal with than the Han people's foot formation.

However, a lion fights a rabbit with all its strength, not to mention that the Yuan and Wei Dynasties have regarded Li Chengzhi as a serious problem. What he is worried about is that if the court does not stop doing anything, there is a high probability that it will join forces with Tuyuhun.

At that time, the three countries will jointly send troops. In any case, there should be four to five million troops. Even if Li Chengzhi mobilizes all the people, he can only raise an army of 100,000 at most. As the saying goes, if the ants kill the elephant, if the three parties really join forces,

In one place, even if there are firearms to rely on, Xihai is afraid that it will inevitably end in defeat.

But it's not impossible to break the situation.

As the saying goes, strike first to gain strength, strike later and suffer disaster. When two armies are facing each other, they will do anything they can. Why do they have to wait for others to come over before they can counterattack?

Huangfu, it's up to you...

Li Chengzhi tapped his finger heavily on the map and drew another circle.
