Cao Pi would not sit still and wait for death. Han Fei knew from the beginning. So he never took the initiative to attack Xuchang City, one to consume the food and patience in the city, and the other to wait for reinforcements to arrive.

The prisoners exchanged food because Mu Qing participated, so the progress went very smoothly. In just three days from the negotiations, 13,000 dan of grain was exchanged for 13,000 prisoners. Of course, Han Fei planted no less than 100 spies and shadows. Mu Qing was also attracted by Cao Pi because of this meritorious service, and he was one of the leaders who had a vague tendency to replace Sima Yi.

After the prisoners were replaced, Han Fei pushed out the five castle carts he had made to disgust Cao Pi, and he had to knock out a few stones every day. Although the person didn't kill many, the color of the stone on the head of Xuchang City changed, which was a goal.

After half a month, reinforcements arrived at the Qi army camp, and Han Fei's second wife Huang Yueying was also here. Huang Yueying did not come here for nothing this time. She brought Han Fei a powerful weapon to steal the city.

This is an object similar to a spear gun in later generations. It is somewhat similar to a crossbow machine. It can fire an iron claw onto the top of the city, and a rope is connected behind the iron claw. Once it is grasped, it can make people climb the rope up to the city.

Han Fei was immediately overjoyed when he saw the weapon brought by Huang Yueying, and still had a plan to take down Xuchang City. However, before his plan could be implemented, the shadow's urgent letter was sent over. It turned out that Sun Quan sent the Grand Governor Zhou Yu to lead 50,000 troops to attack Fuling City along the Yangtze River. Fuling City was under the jurisdiction of Ba County. Now that he was captured by the Wu army, Ba County Prefect Yan Yan immediately asked Guan Yu in Chengdu for help.

Guan Yu did not dare to take it lightly, and immediately led an army of 10,000 to reinforce Ba County after receiving Yan Yan's request for help. At the same time, he urgently ordered Zhao Yun from Hanzhong and Zhang Ren from Jiange to defend, and he was afraid that Cao's army would take advantage of this time to attack. Guan Yu really guessed it right. Just after the Wu army sent troops, Cao Ren and Cao Zhang led their troops to Hanzhong in Chang'an City. The dark clouds of the battle instantly enveloped the entire southwest.

In Hanzhong City, Zhao Yun and Fa Zheng had already received news at this time. Seeing the Cao army approaching, Zhao Yun personally went up to the city to patrol to inspire morale. But even so, some people in Hanzhong City were still panicked.

"Thank you for your hard work in General Zhao! There are 30,000 infantry in the city, plus 3,000 cavalry. It is logical that defending the city is not a problem, but why are people still in panic in the city?" Fa Zheng asked in confusion.

Zhao Yun smiled bitterly and said, "Oh, I really hate Military Advisor Han that he is not here! Otherwise, he could only decide the army of 100,000. With him in charge, this situation would definitely not happen."

After hearing this, Fa Zheng also smiled bitterly and said, "What General Zhao said is reasonable, but now he is far away in Yanzhou. As the saying goes, far water cannot relieve near thirst, so in the end it depends on ourselves!"

"I'm afraid that's all that is the only way! By the way, sir, you go to the Yang family again and ask them to return the grain they borrowed before. Now the Cao army is coming to attack the grain is indispensable." Zhao Yun thought for a while and said. Before, the Yang family borrowed 100,000 dan of grain from Zhao Yun because the autumn harvest was not stored. It had not been returned before. Now the war is imminent, Zhao Yun obviously does not intend to let them drag it anymore. But he didn't know that the grain before was sold by the Yang family, and it was the merchants from Yongzhou who purchased the grain at a high price, and behind it was Guo Jia's work. Cao Cao's death hit Guo Jia very much, making him, who was originally sick, even worse now.

But Guo Jia was unwilling to give up. He thought that he would do his part to Wei State before he died, just to repay Cao Cao's kindness for his friendship. So he planned everything, and now he followed the army with his sick body to the city of Hanzhong regardless of Cao Ren's dissuasion.

Whenever he looked at Guo Jia who was thin and still staying up late to think about the plan to break the city, Cao Ren couldn't help but secretly decided to take Hanzhong this time!

After three more days of time, Zhao Yun finally realized that the Yang family had no food. The news made him feel cold. While trying to find a way to remedy it, he immediately wrote to Jiang Jie from Tianshui City, thinking that he could borrow some food and grass from him first to respond to the emergency.

After receiving Zhao Yun's letter, Jiang Wei immediately prepared to send someone to deliver food. At this time, his son Jiang Wei stopped him and said, "Father, this matter is inappropriate. The Cao army is now at the city of Hanzhong. I am afraid that it will not only not be able to enter Hanzhong City, but also to recruit enemies!" After Jiang Wei became a disciple of Han Fei, Han Fei personally took him for a while. Later, after he returned to Qingzhou, Jiang Wei returned to his parents. However, all the books he read were arranged for him by Han Fei. Not only that, the two of them communicated every month. No matter how busy Han Fei was, he insisted on supervising and checking his studies. Therefore, Jiang Wei's knowledge has grown rapidly in recent years, and his father Jiang Wei no longer regarded him as a child.

Now seeing Jiang Wei stopping him, he asked, "Well, in my opinion, won't you borrow this food?"

"Of course not. My father is now attacking a large-scale attack. If Hanzhong falls because his father does not lend food, how can his father bear this responsibility? So the grain still needs to be borrowed, but it cannot be sent out blatantly."

When Jiang Jie heard what his son said was reasonable, he asked, "Then in my son's opinion, how should we deliver this grain?" Jiang Weiluo pondered and said, "Father, don't worry about this. Cao's army is always when people are relaxed or make mistakes. First, we must send elite troops to figure out the movements of Cao's army. The more detailed the better! Another thing is to contact General Zhao to make an appointment, and we will attack and eat these Cao's army in one sentence! In this way, the food can naturally be transported to the city.

Jiang Jie slapped his thighs and shouted happily: "I'm a good plan, I'm worthy of being my Qilin's son, so I'll do what you said!" After Jiang Jie said that, he immediately arranged personnel. While going to deliver a letter to Zhao Yun, he sent his elite scouts to inquire about Cao's army's movements.
