In 234 AD, through a long-term confrontation, Sima Yi learned that Zhuge Liang had little food and more things, and watched the stars at night, and found that the stars were dim, and he was secretly overjoyed, and he was expected to die of Zhuge Liang, so he did not fight with him, but only practiced soldiers and horses in the camp every day, drank and had fun with the generals, and waited for Zhuge Liang to die to pursue the Shu army.

One day, the scout urgently reported to Sima Yi and said: "The Shu soldiers are retreating, and the mourning in the army is shaking the ground, and white flags are raised everywhere. Sima Yi was overjoyed and said: "Kong Ming is dead, it is advisable to chase him quickly." Then he led the soldiers and his two sons out of the camp to kill Wuzhang. Walking to the dangerous place, Sima Yi was looking up in surprise, suddenly a cannon rang out behind the mountain, the shouting was shocking, only to see the Shu soldiers return to the flag, the Chinese army flag floated out of the shadow of the tree, and a line of big characters on the book said: "Han Prime Minister Wuxiang Marquis Zhuge Liang." Sima Yi was shocked, and saw dozens of generals rushing out of a four-wheeled vehicle; It was Kong Ming who sat on the car: a towel and a feather fan, and a crane soap. Sima Yi shouted: "Kong Ming is still here!" I go lightly into the ground, and fall into its scheme! "Hurry back to the horse and leave. The Shu soldiers rushed down from all sides of the mountain, shouting loudly, and the Wei soldiers were scattered, abandoning their armor and helmets, throwing away their halberds, each running for their lives, trampling on each other, and countless dead. When Sima Yi led the remnants of the army back to the village, he found that Wei Yan had already led the troops to seize the camp, so he did not dare to fight, and urgently led the army to break through and flee to Tianshui County, holding on to wait for help.

It is said that after Zhuge Liang captured the camp of the Wei army, he sent people to garrison the dangerous points on the one hand, and followed Sima Yi's army to Tianshui County on the other. Zhuge Liang divided the 100,000 Northern Expeditionary Army into ten teams, day and night, taking turns to storm the city, and even for days, the anti-loss soldiers were killed and wounded thousands.

In the blink of an eye, Yang Yi, who joined the army, saw that the siege was not going well and his morale was low, so he went straight to the camp to face Chen Zhuge Liang, and said: "Prime Minister, Sima Yi is already in danger, but my 100,000 army has besieged Tianshui for more than a month, but I can't go down, the generals are depressed, and Sima Yi's military strength can breathe. I have recently watched the siege soldiers, the morale is getting worse, and everyone is unwilling to use their lives, do you want to miss the opportunity to reproduce the humiliation of Chen Cang City? May the prime minister make a big plan as soon as possible! ”

Zhuge Liang was sitting on his lap, shaking his fan and laughing: "Wei Gong, I have a heart." I don't know that the siege of the city will not miss the opportunity, if it is delayed for a long time, the food and grass will be insufficient, and the morale will be lost, Sima Yi will then introduce Chang'an reinforcements to join forces with the outside world, not to mention breaking the enemy, we still have to worry about our lives. ”

Yang Yi was shocked and said: "In this case, our army is in danger, it is better to go quickly and make a good plan!" ”

Zhuge Liang smiled again: "Don't worry about the mighty princess, I know how powerful I am, and I also have a corresponding strategy." The art of war is cloudy, the trapped beast is still fighting, although Sima Yi is defeated, the army is still there, if the siege is too urgent, and the battle to the death will survive, then my victory is also a tragic victory. Sima Yi's overthrow was only in a moment, and the only person I was worried about was Chang'an Guo Huai. Chang'an can invade our territory when he advances, and he can defend Yongliang when he retreats, no matter where I use troops, Chang'an can send troops to restrain me. And because our army is dominated by infantry, there are many iron cavalry in Chang'an, and it can be attacked urgently, and it is difficult for me to pursue when I retreat, so I need to take Chang'an if I want to go on a northern expedition. However, Chang'an is far away, the city is high and the walls are strong, and the labor expedition is not conducive to me, so it is necessary to lead the army out of the city and annihilate it in one fell swoop in the field, then Chang'an can be profitable. ”

Yang Yi still has doubts: "The important town of Chang'an, we all know it, and the Wei army also knows it." The prime minister wanted to besiege the city for reinforcements, and led Chang'an soldiers and horses to rescue Sima Yi. If Guo Huai is afraid that Chang'an will be lost, he will refuse to defend it, or attack my Hanzhong. Our army has been attacking the sky and water for a long time, and then returned to the division to save Hanzhong, and the enemy was attacked on the back of the abdomen, and I am afraid that there is still a worry of destruction. ”

Zhuge Liang stroked his palms and laughed: "Wei Gong can have this knowledge, I don't have to worry about it!" I am cautious in my life and never take risks, so Sima Yi has been persistent in treating me and has succeeded repeatedly. I suffered a serious illness and almost died, and I know the truth of the change of power of the soldiers, if I blindly seek stability, I am afraid that I will fall ill again overnight, and the Northern Expedition will be hopeless, so I must not risk the whole army. Although it is dangerous, I also have a perfect plan. This siege of the city, not because my soldiers are not enough, but I secretly instructed the generals to attack the city without the need for death, and secretly raise the elite. The art of war, the way of using soldiers, shows that it is weak, and multiplies it by strength. Chang'an Guo Huai is Sima Yi's favorite general, and the reason why he has not come so far is because he doesn't want to save Sima Yi, and he intends to watch me. He also knew that Sima Yi would fight to the death, but when I was exhausted from fighting, he would lead the iron cavalry to attack him calmly, and Sima Yi would be able to join forces with the outside, and my tens of thousands of foot soldiers would have nothing to hide. Knowing the hostility, he just planned to show the enemy weakness and induce him to attack, I expect that Guo Huai will not attack Hanzhong but focus on me. Just in case, I have sent someone to urge Zitong Guan Xing to lead the army to Hanzhong to garrison, and I will send a detailed work to disturb Guo Huai's mind, at least ten years, more than one month, Guo Huai will come out. I set up an ambush in the middle of the road, and it is as easy as a snap of time! ”

Yang Yi suddenly realized, Zhuge Liang told Yang Yi not to leak the news, while letting the army continue to pretend to attack the city, on the other hand, let people block the Wei army's communication channel, and send a messenger to Chang'an to ask for help in disguise.

In the city of Chang'an.

Guo Huai was pacing back and forth anxiously, and all the generals were arguing endlessly, whether to fight or to help. Suddenly, I heard a report from the guards outside the camp, and the messenger from Tianshui asked to see him, and he hurriedly brought in to inquire about the enemy's situation. I saw a Wei soldier covered in color, holding a blood book, kneeling on the ground and crying, saying that Sima Yi was in danger and begging General Guo to send reinforcements quickly. Guo Huai was suspicious of the letter, stared at the letter for a long time, and suddenly laughed, calling for the people to help him and take care of him, and asked the generals to pack up the soldiers and horses and set out for the expedition in the future.

All the generals were shocked and said: "The general is a national responsibility, how can he leave the important town of Chang'an and go to danger because of a letter to the envoy?" “

Guo Huai continued to laugh when he heard this, and said: "Don't I know that the words of the messenger may not be true? I expected that this messenger must be Zhuge Liang's meticulous work, and he sent him to lure me into battle, besiege the city for reinforcements, and set up an ambush in the middle road. ”

The generals were puzzled and said, "Since the general knows that it is fake, why do you want me to wait for the whole army to fight?" ”

Guo Huai smiled and said: "You only know one, not only two." Sima Gong was newly defeated and besieged in Tianshui by the Shu army, and it was reported that Zhuge Liang's 100,000 army besieged the city, how could he let a messenger break through? for he was informed that the messenger would be false. What I am worried about is why Zhuge Liang tempted me carefully. If I knew it, I would not have come to my aid, and I would have turned to attack Hanzhong. Now I suddenly realized that Sima Gong was besieged and would inevitably fight to the death, Zhuge Liang could not attack for a long time, the food and grass were not good for a long time, the morale was low, and the longer the delay was not good for him, it was to lure me to fight in a hurry. I will plan now, and attack again in a month, when Zhuge Liang's generals are exhausted, Sima Gong's qi recovers, and the inside and outside should be combined to attack before and after, then the Shu army can be broken, and Zhuge Liang can be captured! ”

When all the generals heard this, they all bowed, and some people said: "In this case, why did the general simply not save him, or delay it for a few more months, and wait for him to retire when his food is exhausted?" ”

Guo Huai shook his head and said: "No, Sima Gong is my Great Wei barrier, I can't help it, and we are all greatly favored by Sima Gong, how can I sit and watch him be surrounded and not saved." Now the whole army will be reorganized, and the whole army will set off a month later to save Sima Gong from danger, kill Zhuge Liang, and make immortal achievements! ”

All the generals shouted victory and went separately to reorganize their troops and horses.

After January, Guo Huai reorganized his troops and led the whole army to set off from Chang'an. On the one hand, Guo Huai sent people to quickly inform Sima Yi that he must hold on, and drag the Shu army to facilitate internal and external attacks; On the one hand, he sent people to inquire about the news of the Shu army, and when he learned that the siege of the Shu army was getting worse and the morale was low, he immediately ordered the whole army to advance at full speed and go straight to Tianshui.
