Li Shimin still knows the story of besieging Wei and saving Zhao.

After all, he had been born in the military before and knew all kinds of military steps.

But now Li Shimin couldn't understand what Zhang Feng said about encircling Wei and saving Zhao. He hurriedly asked, "Fengzi, what you said about encircling Wei and saving Zhao is that the emperor wants to send troops directly against Turks?"

"Who told you?"

"If there is nothing wrong with the emperor's head, no, no one will say so. If you don't believe it, you have to ask."

Li Shimin was despised by Zhang Feng again.

But it doesn't matter.

Li Shimin was not annoyed and continued to ask, "what do you think of this troop dispatch, whether it will go out or not, where it will go, and what does it mean to encircle Wei and save Zhao?"

Li Shimin is in a mess now.

Where can you think of so much?

Zhang Feng held his mouth like looking at a steamed stuffed bun. He looked at the anxious Li Shimin and shook his head slowly.

"Say you don't understand, you really don't understand. Come on, I'll say it carefully. It's also to popularize science for you, or I'll be ashamed of you if you go out!"

While talking, Zhang Feng took out a piece of straw paper, pen, ink, paper and inkstone and a small piece of thin bamboo stick from the inner room, and roughly drew the Tang Dynasty and the surrounding terrain on the paper.

Then he pointed to the intersection of Tubo and Tianzhu Zhenla and said, "look, this is the intersection of the Three Kingdoms. Look here."

While talking, Zhang Feng pointed to Anxi Du's guard house with a thin bamboo stick, and then wrote three words "kuci city" there. In an instant, Li Shimin could understand the approximate location of the map from this circle, large and small.

Then, Zhang Feng drew a long dotted line from Liantong road and Longyou Road near kuci city and said: "If our soldiers start from Guannei Road, unite all the government soldiers on Longyou Road, deploy defense along the way, then insert the oblique line from kuci City, cross Tubo, unite some Datang soldiers in Tubo, and directly enter Tianzhu, wouldn't it solve Zhenla's dilemma in an instant?"

Li Shimin was stunned.

Staring at the map, I couldn't speak for a long time.

I also instantly understood what Zhang Feng meant by encircling Wei and saving Zhao, but what's the use of this?

"Fengzi, I heard that the Tuli old thieves have arranged 100000 elite from Youzhou, didn't you also say? These 100000 people are likely to have entered Tubo and Tianzhu. The war between the two countries is also likely to be a conspiracy related to these Turkic elite. Don't you become enemies in the back and in the back?"

"You should know that the troops that Datang can mobilize now, plus the soldiers of various prefectures, can be up to 200000. If all these people are trapped, won't my Datang completely open the west gate to the Turks?"

"And you should be clear that Tuli and Jieli have always been at odds. What does it mean that the 100000 elite of Tuli can enter the territory of West Turkic Jieli? It means that Tuli and Jieli should have reached a consensus. Therefore, I think there are more than 100000 Turks, probably 200000, or 300000 people in Tianzhu, basically Turks Do you believe it? "

Li Shimin said everything he wanted to say.

Zhang Feng looked at Li Shimin in surprise: "yes, Lao Li, unexpectedly, you still have a little progress."

"You guessed right. Although Tuli and Jieli are uncles and nephews, they have long been in the same situation. Coupled with the disaster and food shortage, there has been a wide range of friction. It is a big problem that Tuli people can enter western Turkistan safely, but until now, there is no news. What does that mean? There is fraud!"

"The reason why I said that I wanted to encircle Wei and save Zhao and take Kucha city as the point was actually planned according to the emperor's consistent strategy. As an important fortress, Kucha city can go up to Turks and down to the hinterland of Tubo. Suppose you have 100000 people, I think even if you walk into Tubo with 100000 people doing nothing, it will make Tianzhu and Turks nervous,. ,”

"But what's the use?"

"How do we want to lift the situation in Zhenla now?"

Li Shimin spread his hand.

Zhang Feng patted Li Shimin on the shoulder and said, "don't worry, don't worry, listen to me."

Li Shimin's face turned black.

"Pick the point."

"All right!"

"In fact, if you take 100000 troops from Kucha and enter Tubo, the purpose is to attract the attention of Turks and Tianzhu, and then enter Tianzhu with a high profile. What do you think will happen if you 100000 people enter Tianzhu?"

"Even at this time, Tianzhu announced that 300000 troops were stationed in Zhenla, that is to say, his defense focus was on the side of the intersection with Zhenla, and as for the side close to Tubo and Turks, it would be a defense gap. Once he learned about this, do you think he will continue to attack Zhenla or return?"

Li Shimin stared at the simple map drawn by Zhang Feng. He thought carefully and understood it in an instant.

"Is that what you said about encircling Wei and saving Zhao?"
