Since retreating to Tongguan, Cao Zhen sent a large number of scouts to the vicinity of Chang'an to investigate the enemy's situation. Gradually, Cao Zhen developed a habit of standing on the city gate tower every afternoon and waiting for the scouts to come back, and Cao Zhen would feel at ease when he got the latest information.

The scout also knew that Cao Zhen must be waiting on the city gate tower at this time, so after the scout entered Tongguan, he went straight to the city tower and wanted Cao Zhen to report.

"Is there anything unusual about the Hu people?" Cao Zhen asked.

"Back to the governor, just like yesterday, Kebineng has not moved in the slightest."

"What about the Shu army? Did the Shu army in Chang'an City send troops? Cao Zhen then asked.

"No, the Shu army in Chang'an City is still sticking to Chang'an City. Zhuge Liang of Tianshui did not make the slightest movement, but strictly guarded the line of Tianshui. ”

Cao Zhen nodded, thought for a while and said to the guards behind him: "Order, immediately convene the generals and raise the account!" ”

……

looked at the military ministers under his command, Cao Zhen. opened his mouth and said: "Now that the Shu army and the Hu people are holding each other in Yongzhou, what do you think?" ”

Guo Huai was the first to stand up and said, "Governor, now. The Hu people just camped on the spot and did not fight against the Shu army, I think Kebi Neng must have retreated. ”

"You mean Kobi wants to run away?" Cao Zhen asked.

"Yes, all the cities on the south bank of Weishui have been . The Hu people have looted everything, and now there is no way to rob them, I think the Hu people are ready to go back to the grassland. It's just that now Zhuge Liang led the army to choke the key land of Tianshui, and there was Weishui to block it, Kebineng couldn't cross Weishui and was trapped south of Weishui. So I think Kebi can wait until the autumn and winter season, after the Weishui has dried up, and then cross the Weishui. Guo Huai continued.

"Berji is right, but this Kebi can really be bold and daring. Camped on the south bank of Weishui, if Liu Bei of Chang'an City and Zhuge Liang of Tianshui sent troops together, and attacked from both sides, Kebineng would inevitably lose a lot. It's just that Zhuge Liang of Tianshui and Liu Bei of Chang'an are all standing still, which somewhat surprises me. Cao Zhen said.

"I think Liu Bei and Zhuge Liang may be waiting for the right time." Outer part. Huai continued.

Cao Zhen nodded: "Waiting for the opportunity?" It's possible. Since that's the case, I. We must pay close attention to the situation in Chang'an, once Liu Bei really sends troops to attack Kebineng, we will send troops to raid Chang'an. ”

"Dudu, I think Liu Bei. It is not going to send troops to attack Kebineng. Not only Liu Bei won't, but Zhuge Liang will only defend Tianshui and won't attack Kebineng" A voice suddenly sounded, Cao Zhen looked towards the voice, and now it was the newly arrived lieutenant general Deng Ai of the Dianjun Army.

Sima Yi vigorously recommended Deng Ai in front of Cao Pi, so Cao Pi sent Deng Ai to the front line of Tongguan, and now Deng Ai has been coming to pass for more than two months. Although there has been no fighting for two months, Deng Ai has been paying attention to the situation in Yongzhou.

"Why did Shizai say that?" Cao Zhen asked.

"Dudu, what General Guo Huai just said is right, Kebineng has already retreated. And Zhuge Liang and Pang Tong are dragons and phoenixes among people, how can they not see that Kebi can want to retreat? Dare to ask the governor, if the governor is in Tianshui, and Kebi can prepare to withdraw to the grassland, what will happen to the governor? Deng Ai asked rhetorically.

Cao Zhen thought for a while, and said: "There are nearly 300,000 Hu people under Kebineng's command, and they must not be a tough enemy, if Kebineng wants to withdraw to the grassland, I will definitely not stop it." ”

"What Du Du said is that the Hu people are powerful, and now that the Hu people are going to withdraw to the grassland, Zhuge Liang should be unable to ask for it, hoping to send this group of Hu people away as soon as possible. However, Zhuge Liang set up defenses in Tianshui to block the Hu people, making it clear that he didn't want the Hu people to return to the grassland. In this way, Zhuge Liang is preparing to annihilate the Hu people's coalition army. Deng Ai continued.

Cao Zhen nodded, without words, but his face was a little gloomy. Just now, Guo Huai had already speculated that the Shu army was going to annihilate the Hu people, and what Deng Ai said in front of him was tantamount to nonsense.

I only heard Deng Ai say unhurriedly: "If the Shu army fights with the Hu people, it will inevitably lose both, but it will be profited by fishermen such as us, and Zhuge Liang is cautious and scheming, and he will definitely think of this, so I expect that Zhuge Liang already has a way to win in his heart, that he can annihilate the Hu people, and he will not consume too many men and horses." ”

"Why win?" Cao Zhen hurriedly asked.

Deng Ai shook his head: "The last general has just arrived in Tongguan, and he doesn't know much about the terrain of Tongguan. However, Zhuge Liang is easy to use strategies, if my expectations are good, Zhuge Liang wants to completely annihilate the Hu people, and there are only three plans that are feasible. ”

"Which three?"

"Use fire, water, and space! It's just that Zhuge Liang will use which one, I don't know. Deng Ai replied with a wave of his finger.

This time, everyone in the account nodded in agreement. In ancient times, the most commonly used tactics were these three tactics.

Cao Zhen lowered his head, thought for a moment, and said: "Kebineng's camp is only on the plain, and there are no dense trees around, so it should be impossible to attack by fire. It is possible to use the separation meter, but now it is summer, and the rain is abundant, so I think it will be more likely to be attacked with water. ”

"Governor, I don't know how much water is going in Weishui recently?" Deng Ai asked suddenly.

"Shizai, don't you say that I forgot, this year's Weishui seems to be a lot calmer than in previous years. At this time in previous years, Weishui was already choppy. Guo Huai netbsp; "Could it be that Zhuge Liang is really going to decide Weishui?" Deng Ai muttered.

Although Deng Ai's voice was small, everyone around him heard it. Everyone's faces looked incredulous. There are not many large and small rivers in Yongzhou, but only most of Yongzhou, which is connected by Weishui, only reaches the Yellow River at Tongguan. If other rivers are broken, it may cause local floods, but if Weishui is broken, both sides of Weishui, the richest in Yongzhou, will fall into a Ze country.

"Zhuge Liang shouldn't be so ruthless! If Weishui is decided, won't Yongzhou be destroyed! Besides, Liu Bei prides himself on being benevolent and righteous, so he shouldn't use this poisonous trick! Cao Zhen muttered.

"Governor, I don't think so. Liu Bei is hypocritical, Zhuge Liang is scheming, and Pang Shiyuan is cunning and cunning, so it is hard to guarantee that they will not do this. Governor, think about it, if His Majesty were to sit in Chang'an, how would he choose? Deng Ai said.

"Your Majesty?" Cao Zhen was stunned, if Cao Pi was in Chang'an, how would he choose?

Thinking about Cao Pi's past work habits, Cao Zhen's body trembled, if Cao Pi was allowed to choose, Cao Pi would definitely choose to flood Yongzhou without hesitation.

"Dudu, in fact, I think that if Liu Bei floods Yongzhou, I'm afraid it will be good news for us." Deng Ai continued.

"Shizai, please."

"If the Shu army really breaks Weishui, Yongzhou will inevitably be full of victims, at that time we only need to send a fine work to infiltrate Yongzhou, provoke public resentment, it is the disaster victims who rise up, Liu Bei will inevitably send troops to suppress, and then we can take advantage of the situation to kill back Yongzhou and recapture Chang'an." Deng Ai said.

"Good plan, Governor, I think Shizai's plan is feasible."

"Governor, I also think it's a good idea."

The soldiers in the tent expressed their support for Deng Ai's plan, and even Cao Zhen himself felt that Deng Ai was right.

"In that case, let's do what we do."

……

Chang'an City.

"Shiyuan, the Hu people have been retreating for so long, why don't you let me lead the troops out?" Zhang Fei shouted in a loud voice.

"The third general should be in a hurry, wait, wait......" Pang Tong said, took a sip of the tea in his hand, and then gently shook the feather fan in his hand to drive away the heat.

"Wait, wait, wait! Every time I come, you want me to wait! When will it be......" Zhang Fei sat aside unwillingly, directly picked up Pang Tong's teacup, and poured all the tea in his mouth.

"Three generals, please calm down, I already have a plan in my heart, so I don't need to worry too much." Pang Tong's tone was still so calm.

"Already in the know? Shi Yuan, tell me honestly, have you discussed it with Kong Ming? Kong Ming sent Gao Xiang here a few days ago, is this just for this? ”

"What the three generals said is good, but this time the plan was not thought of by me, but by His Royal Highness the Crown Prince."

"What did Adou think? Shi Yuan, tell me quickly, what is the plan? ”

"Haha...... Heaven cannot be leaked 1ou. After Pang Tong finished speaking, he shut up and didn't go on.

"Hmph, and that Zhuge Kongming has a virtue, there are always things hidden." Zhang Fei said with a resentful face.

"Third general, I think His Royal Highness the Crown Prince will return to Chang'an soon, and when the time comes, you can just ask him directly."

……

On the north bank of Weishui, Adou Daying.

Adou kept playing with the bag in his hand, this bag was sent by Zhuge Liang, and the person who sent the bag also brought news to Adou, Weishui has already arranged it, Adou only needs to open the bag in order.

Adou opened the first bag and took out the silk cloth inside, only to see seven big characters written on it: Daytime green insects fly all over the sky.

"Daylight green worms flying all over the sky?" Adou was stunned, and then immediately called Zhang Wei.

"Zhang Wei, go and investigate immediately, in the past few days, there are not many insects in the fields during the day." Adou commanded.

"Yes!" Zhang Wei replied subconsciously, and then Zhang Wei seemed to have figured out something, and said with a bitter face: "Your Royal Highness the Prince, it is summer now, and there will definitely be a lot of insects in the fields." ”

Adou reacted at this time, and his order was unclear. So Adou hurriedly explained: "It's that I didn't make it clear, you go and check if those insects in the field are flying all over the sky recently." ”

"The last general commands." Zhang Wei immediately walked out. And after about an hour, Zhang Wei returned.

"Back to His Royal Highness the Prince, I sent someone to ask, in the past two or three days, insects are indeed flying all over the sky during the day." Zhang Wei said.

"Daylight green insects fly all over the sky! It's really hit! Adou muttered, and then Adou hurriedly opened the second bag, only to see that there were also seven big characters written in it......
