Jiang Wei's judgment was correct, because Cao Liang, who occupied most of the northern territory, was reluctant to submit to Sima Zhao. So in August, Cao Liang ascended the throne in Luoyang and inherited the Wei Dynasty's throne. The situation of the three kingdoms became a four-part world. Wei occupied the northeast, Jin occupied the northwest, Shu occupied the southwest, Wu occupied the southeast, and the four countries occupied one side.

But Jiang Wei believes that such a situation will definitely not last long, because Cao Liang's Wei State and Sima Zhao's Jin State both originated from the former Cao Wei State. As the saying goes, there is no day, and there is no two kings. Cao Liang will definitely not tolerate Sima Zhao's usurpation and rebellion, and there will be an unprecedented war on both sides next.

This will be a war about status. The victory or defeat of the war will determine who is orthodox and who is qualified to inherit the throne of Cao Wei. Therefore, this war must be a war.

As long as the battle between the two sides begins, the Jin army will have no time to look west. The defense of Longxi is empty, which is the best opportunity for him to go on the northern expedition. If everything goes well, Jiang Wei will definitely be able to take down the counties of Longxi and expand the territory of Shu Han to Yongzhou and Liangzhou.

When Jiang Wei received the exact news that the Wei army had attacked Tongguan, Wuguan and Pubanjin, he immediately prepared to send troops. Jiang Wei had already had everything, only the east wind was lacking. The army of Wei and Jin sides fought on the eastern front of Guanzhong, which was the east wind he had long been looking forward to. Such an opportunity was once a year old, and Jiang Wei definitely refused to miss it. So Jiang Wei launched a 50,000 army, with Xiahou Ba as the vanguard, Liao Hua and Zhang Yi as the left and right wings, and went to Qishan.

Jiang Wei's preparations for this Northern Expedition were more than any other time. Whether in terms of the troops invested or the reserves of food and grass, they were much larger than any previous military operation. The 50,000 troops mobilized by Jiang Wei this time were half of the total force of Shu.

With the population of less than one million in Yizhou, it is indeed overwhelming to support about 100,000 troops and 40,000 officials. Therefore, the military organization of Shu has been maintained at about 100,000 for a long time. It requires troops to defend Chengdu, Nanzhong, and Yong'an. Therefore, Jiang Wei mobilized 50,000 troops to the Northern Expedition this time, and almost all the mobile troops were drawn, which completely reached the upper limit of the Shu army.

Although Jiang Wei's resistance to the Northern Expedition was much smaller after Fei Yi's death, there were still constant voices of opposition from the court. Among them, the local Yizhou faction headed by the Guanglu doctor Qiao Zhou was Jiang Wei's biggest opponent, and the latter leader Liu Chan was even a very soft-hearted person. He obeyed the eunuch Huang Hao. Jiang Wei's Northern Expedition was united in the front line, but the constraints at the rear made him feel helpless.

Therefore, Jiang Wei will never waste the troops as he sent troops this time. Otherwise, once the later ruler Liu Chan was persuaded by Huang Hao and his ministers, Jiang Wei would have to go on the Northern Expedition again, the difficulties would become extremely great.

Only when Jiang Wei conquered Longxi and gained a foothold in Yongliang could he block the leisurely mouths of the ministers in the court. Therefore, this time the dispatch of troops was almost forced to succeed. If Jiang Wei wanted to exchange for support from the court, he had to make achievements.

However, before Jiang Wei sent troops, the defense situation of the Jin army in Longxi was carefully reconnaissed. In the past, the Wei army's permanent garrison could basically be maintained at 70,000 to 80,000, or more than 100,000. When the Shu army left Sichuan, it faced a large number of opponents and had obvious disadvantages in terms of military strength. It could only be planned by the main future and won through strategies.

But this time the situation was obviously different. The defense focus of the Jin army turned to the Guanzhong East Line, so on the Longxi Line, the troops were significantly weaker, with only about 30,000 permanent troops. This time, the Shu army could finally be proud and overwhelmed the Jin army in terms of military strength.

This is obviously the benefit brought to the Shu army by the tight situation in Guanzhong. Jiang Wei finally waited for his long-lost opportunity. In the past, Jiang Wei always had to fight with few enemies and few enemies with many enemies. Even if Jiang Wei had outstanding military talent, such passive battles were really difficult to fight. However, it was not easy for him to get a small gain every time and he could still get away with it without hesitation.

This time, Jiang Wei finally had an excellent opportunity. Most of the Jin army was restrained on the front line of Tongguan. Only more than 30,000 people from Guo Huai were left in Longxi to guard. This was not a god-given opportunity. If Jiang Wei could not make achievements this time, then he should have retired from the field and retired to the world.

With the control of the Jin army's defense in Longxi, Jiang Wei's expedition this time was full of confidence and confidence. Now Jiang Wei is over the age of knowing destiny, but he is still full of energy and fighting spirit. The handsome boy in white robes and silver armor is hard, and his years of military career has become dark and vicissitudes, with hard lines, and a little cold, without being angry but powerful.

The army of Shu Kingdom was winding all the way, traveling through the steep valleys of the Qinling Mountains. However, this mountain road was nothing to the Shu army. Over the past few decades, they had already traveled all over the valley, so this advance was more familiar with it.

Xiahou Ba, who served as the vanguard, was even more anxious. After the Gaopingling Incident, Xiahou Ba was persecuted by the Sima family and had to flee Shu and seek refuge. Now he is in Shu, he is a high-ranking general of the chariot and cavalry, and is a royal relative. Logically speaking, at his age, it should be time to enjoy his old age. However, Xiahou Ba often has a revenge, and this time he volunteered to fight. The Sima family forced him to have no place to stay in the Central Plains. Today, he finally had the opportunity to avenge the Sima family. How could he miss such a once-in-a-lifetime opportunity?

Qishan Fort is the exit of the Qishan Ancient Road and an extremely important strategic location. When the Wei army was strong, it often stationed heavy troops in Qishan Fort to prevent the Shu army from invading from Qishan Road.

After all, Zhuge Liang launched three attacks from here for the five Northern Expeditions. How could the Wei people not know the importance of Qishan Fort, so it was normal to garrison heavily in Qishan Fort.

However, after Zhuge Liang's death, Wei and Shu had not fought for many years. Even though Jiang Wei attacked several times, he walked towards Longxi Road, which was more westward. In addition, Guo Huai's troops were limited, so the Qishan Fort was abandoned. After the Shu army arrived at Qishan Fort, it was already overgrown with weeds, broken walls and a broken scene.
