Jiang Wei did not dare to be careless, so he took Xiahou Ba to Chengdu and personally introduced him to his later master Liu Chan. Jiang Wei reported: "Sima Yi of Wei State murdered Cao Shuang, and now he came to recruit Xiahou Ba to kill him, so Xiahou Ba surrendered to our country. Now Sima Yi and his son are in power, and the young emperor of Wei State, Cao Fang, is weak. Wei State is about to be in danger. I follow the order of the Prime Minister. After occupying Chang'an for a while, I also stocked up some food and grass. I am willing to lead my troops, with Xiahou Ba as my guide, to conquer the Central Plains and revive the Han Dynasty to repay Your Majesty's kindness and fulfill the wishes of the former Prime Minister Kong Ming." Fei Yi was ordered by Shangshu. The admonishment said: "Now that Jiang Wan and Dong Yun have become obsolete in our court, there is no one else to manage the internal affairs, and the prime minister has been defeated. We should wait for a better time and not act rashly."
Jiang Wei argued: "No, life is fleeting. It only takes a few years. It will be difficult to wait until the so-called good opportunity comes. So when will the great cause of unifying the Central Plains be completed?"
Fei Yi said: "Sun Tzu said that if you know yourself and the enemy, you will be victorious in every battle. We are not as good as the former Prime Minister Kong Ming. He can't restore the Central Plains, let alone us? And the current Prime Minister has no order to send out troops. How about asking him first? ?”
Jiang Wei said: "After the Shu army occupied Chang'an, we took the opportunity to occupy Longshang. I often went to get closer to the Qiang people. Now we are asked to serve as our foreign aid. Even if we cannot occupy the Central Plains, we can capture Luoyang and shake the Wei state." foundation, then the Central Plains will be easier to plot, and Prime Minister Yu Yi is based in Wancheng, Jingzhou. He is not familiar with things in the north, and you cannot consult him on everything."
Liu Chan nodded and said: "It is good that the general has such an ambition, but the Northern Expedition to the Central Plains still needs a long-term plan. I will write to the prime minister to see what his opinion is." After saying this, he ignored Jiang Wei's advice. The court broke up immediately and the letter was sent out on the same day.
The letter soon arrived in Wancheng. At this time, Yu Yi was educating his children and paying homage to his deceased eldest son, Yu Daye. When he heard that a letter had arrived from the court, he opened it and read it. After reading the content, Yu Yi seemed a little unhappy and said to Huang Shumin: "Jiang Wei did this just because our army was defeated last time because of the video incident, so he didn't trust me very much and wanted to help regain the king's power and establish own identity.”
Xiaoli was also nearby and asked, "Did you send someone to assassinate him?"
Yu Yi smiled and said: "That's not the case. Now it is true that Xiahou Ba came to surrender, and it will be sooner or later for Sima Yi to usurp the power of Wei. Although I have been newly defeated, Shu still has national strength. If Jiang Wei wants to conquer the Central Plains, That’s understandable.”
Huang Shumin was still dissatisfied and said: "Everyone in the Shu Kingdom knows that the Prime Minister is respected. Jiang Wei deliberately avoided the Prime Minister and went directly to the Emperor of Heaven. He is really arrogant!"
Yu Yi smiled and said: "I know this matter well. Jiang Wei is also doing it for the Kingdom of Shu. Since he has a better opinion, it doesn't hurt to try it." In fact, Yu Yi has an open-minded attitude towards this matter, because Liu Chan did not Make your decision immediately, but write a letter to ask yourself. This effect is enough.
So Prime Minister Yu Yi's reply came to the court. After reading it, Liu Chan smiled and said: "Since I want to attack the Wei State, I must do my best and not undermine the spirit of the Shu State. Now that our country is newly defeated, There can be no more separation, don’t let me live up to my expectations of you.”
Jiang Wei paid his respects, said goodbye to the court, and came to Chang'an with Xiahou Ba to discuss raising an army.
Jiang Wei said: "Although the Prime Minister promised us to send troops, he will not provide much help, so we can send envoys to form an alliance with the Qiang people, and then prepare food and grass. Now we set up camp outside Chang'an City to form an arm's length relationship with Chang'an. According to According to Prime Minister Kong Ming’s method, we will attack slowly and slowly to capture Luoyang.”
In the autumn and August of the same year, the Shu army generals Ju'an and Li Xin were sent to camp outside Chang'an City with 15,000 troops and horses, and then arranged for follow-up food and grass. The Wei army quickly obtained the information and reported it to Guo Huai and Luoyang were the foundations of Wei's capital, so they naturally attached great importance to it, so he sent his deputy Chen Tai with 50,000 troops to fight the Shu army. Ju'an and Li Xin each came out with a team of troops to fight because they had too few troops. , so we can’t resist and can only retreat.
Chen Tai sent soldiers and horses to surround and attack him, and at the same time sent another team to sneak attack on the grain road. There was a shortage of food in the camps of Ju'an and Li Xin. After Guo Huai arrived with his soldiers and horses, he saw the terrain and was very happy. After returning, After discussing with Chen Tai, he said: "The place where Shu will camp is very mountainous. According to my many years of experience, the water source must be in short supply. We need to go outside to find water sources. If we cut off the water source near his camp, then the Shu army will be in trouble." He will be thirsty, and he will be in chaos without a fight."
So that night, he sent soldiers to dig at the water source and cut off the water source of the Shu army. There was no water in the camp. Li Xin could only take his soldiers and horses to check the water source problem. The enemy came fiercely and besieged the temporary camp. It was so tight that Li Xin was unable to come out even if he fought to the death with his troops and horses, so he had to retreat. There was no water source in the camp in Ju'an. They met Li Xin and they agreed to go together and charge with their troops and horses to solve the water source problem. . However, the Wei army seemed to have been prepared for it. After several battles, they had no choice but to retreat, so the sergeants became thirsty and became a little confused!
The two discussed: "Sir Jiang Wei's troops have not arrived yet. I don't know why."
Li Xin said: "It's not an option to just sit there and wait for death. I should risk my life and break out of the siege to find Lord Jiang Wei for help." So he led a dozen cavalrymen, opened the gate of the camp in the middle of the night, and fought out. The Wei army was surrounded on all sides, and he fought to the death. He broke out of the siege, but the rest of the soldiers and horses who followed him were killed in the chaos. Only he escaped and was seriously injured.
That night there was a strong north wind and the temperature dropped suddenly. The Shu army in the city could only eat the melted snow water and dry food together.
In this way, Li Xin broke out of the siege and returned to Chang'an along the path. After walking for two days, he happened to encounter Jiang Wei coming towards him with his troops. He dismounted and worshiped: "We camped in Weinan according to the order, but the Wei army filled us up." The water source, the soldiers were thirsty, but fortunately Tianlai University turned the snow into water, but at this time everyone was surrounded and very critical."
Jiang Wei explained: "I didn't come late on purpose, but I was gathering with the Qiang people to get their support. There were too many banquets, so I got sick of it." So he sent someone to send Li Xin to Xichuan for treatment.
Jiang Wei asked Xia Hou Ba Dao: "The Qiang soldiers and horses have not yet caught up. The Wei army has now severely besieged the Weinan camp. Does the general have any good ideas?"
He replied: "If we wait for the Qiang soldiers and horses to arrive, then the Weinan camp will be in danger. I estimate that the soldiers and horses coming from the direction of Gaoling in Yongzhou will definitely try their best to attack Weinan. Then Yongzhou will naturally be empty, and the general can cross with his troops and horses. Cross the Yellow River and detour behind the Yongzhou soldiers and horses. When Guo Huai and Chen Tai know about it, they will definitely go to the rescue, and then the crisis in Weinan will be relieved."
Jiang Wei was very happy after hearing this and said with a smile: "What a move to surround Wei and rescue Zhao!" So Jiang Wei led his troops and horses across the Yellow River overnight and headed towards Gaoling in Yongzhou.
