Therefore, Cao Liang formulated a step-by-step combat strategy, which was to gradually compress the living space of the Shu army. During this stage of combat, Cao Liang did not pursue the number of annihilated enemies, but wanted to use the powerful deterrence power of the Wei army to force the Shu army back, and finally drove them all to Chengdu, and then gave a fatal blow.

This strategy is not too difficult to implement. It is almost certain to win this war with the strength of the Wei army. There is no suspense anymore. The only suspense is how long it will take for the Wei army to do.

In fact, with the current trend, as long as the Wei army launches a general attack, it will not take long to capture Chengdu without considering the cost of casualties. Even when the Central Army attacked from Nanzhong to Shuzhong, it was not impossible to attack Chengdu in one go.

But what Cao Liang is now considering is not only how to destroy Shu, but also consider achieving this goal with the minimum cost of casualties.

The superior army attacks the plan, the second is to attack the diplomatic relations, and the second is to attack the troops. The subordinate army attacks the city. Only the best strategy is to defeat the enemy without fighting.

Cao Liang knew that the Shu court was not a solid piece now, and not everyone would be determined to support Shu. Cao Liang could clearly remember that in history, when Deng Ai's troops were at the city, there were many surrenders from Shu. Even the Shu emperor Liu Chan could not withstand the foolings of a large group of surrendered ministers. In the end, he abandoned Chengdu and surrendered Deng Ai.

In fact, all the three people who could stand firm and not surrender were not from Shu. Jiang Wei Simalun was from Wei and Lu Kang was from Wu. At present, more than 80% of the army in Shu was in the hands of these three people.

These three people can be said to have deep hatred with Wei State, and this hatred is almost unimaginable, so the possibility of persuading these three people is almost zero.

Therefore, in the subsequent battle, Cao Liang did not rush to achieve success, but ordered the three governors Deng Ai, Yang Hu and Du Yu to coordinate simultaneously and advance steadily, and continue to put pressure on the Shu army in three directions.

Now the three giants of the Shu army are guarding one direction. Jiang Wei is guarding the south of Chengdu in Nan'an, Lu Kang is guarding the east of Chengdu in Deyang, Sima Lun is guarding the north of Chengdu, and the three Shu army guarding one side, showing a desperate battle.

There are still 20,000 imperial guards in Chengdu, all of which are commanded by Sima Zhan, the general of the guard of the Guizhongdu. This is also the last line of defense for the Shu army. However, if the defense line outside Chengdu is lost, it is completely impossible to rely on Zhuge Zhan's 20,000 people to defend the huge Chengdu city.

Therefore, the tens of thousands of Shu troops on the outer defense line are the last hope for Shu Kingdom to stick to the end. Although Jiang Wei was in Nan'an and only needed to resist the Wei army from the south, that is, Yang Hu's Central Army, Jiang Wei's mind was not just here. He needed to worry about the entire Chengdu defense plan.

The successive fall of Yong'an and Jiange was an extremely heavy blow to Jiang Wei. Everyone knows that the reason why Shu Kingdom can exist under the heavy pressure of Wei for so long is that it is because the road to Shu is more difficult than the sky?

It is precisely because the two dangerous passes of Jiange and Yong'an, one north and one east, became the gateways of Shu, that Shu has always been able to rest assured. For the Wei army, even if they have the advantage in strength, they will never be able to break through these two passes. As long as the Shu army can firmly guard the Jiange and Yong'an, no matter how hard the Wei army makes, there will be no result.

But Jiang Wei obviously underestimated Cao Liang's determination to destroy Shu, thinking that with the two heroic passes of Jiange and Yong'an, it would be enough to stop the Wei army.

But Jiang Wei never expected that the Wei army would launch a raid from the distant southern line and invade Nanzhong. Nanzhong was indeed the weakest link on the Shu national defense line. Jianshou Prefect Huo Yi had only about 10,000 troops in the hands of him. With such a little force, it was a drop in the bucket and could not stop the attack on the Wei army.

Huo Yi was loyal to Shu Kingdom. In the end, he would rather die than surrender to the Wei army. In order to deal with the crisis in Nanzhong, Huo Yi even tried his best to force the barbarians to send troops. Although the final result was that he could not stop the progress of the Wei army, at least Huo Yi did his best and also won Jiang Wei the time to return to the aid of the Wudao.

If the South Central fails at speed, Jiang Wei may not even be able to wait for the opportunity to return to the aid. After all, it is at least a thousand miles away from Yong'an to Wudao. When the news of the South Central Declining reached Yong'an, Jiang Wei mobilized his troops at that time, and the daylily would probably be cold.

It was precisely because Huo Yi lured Meng Li that his 100,000 barbarians fought with the Wei army to fight for life and death. This not only played a role in blocking the Wei army, but also killed two birds with one stone and weakened the power of the barbarians in the south.

Although Jiang Wei has always been in charge of the military affairs of the Northern Expedition and his attention is on the Northern Line, he is not unclear about the situation in Nanzhong. Since Zhuge Liang's southern expedition, there has been no rebellion in Nanzhong that has affected the entire Nanzhong for decades. Occasionally, some small-scale rebellions have a very small scope and will not affect the overall situation in Nanzhong.

But if they are not of our race, their hearts will be different. Although Meng Huo, who rebelled in Nanzhong, was conquered by Zhuge Liang's personal charm, after Meng Huo's death, could their sons continue to be loyal to the Shu court?

Obviously this is impossible. After Meng Huo's death, his four sons had their own hands and soldiers, and even fought for the sake of the inheritance. It was hard to believe that these few sons would have no ambitions and would not want to stand on their own in Nanzhong.

Huo Yi is a rare talent to be able to firmly control the situation in Nanzhong in this situation of internal and external troubles.

Unfortunately, the opponent he encountered was a long-time general like Yang Hu. Even if Huo Yi tried all his skills, it would still be difficult to defeat. In the end, he died in a foreign land and would never have the chance to return to Chengdu again.

The fall of Nanzhong became the last straw that overwhelmed Camel. Even though Jiang Wei knew about the Wei army's attack on Shu in three directions very early, he could not draw too many troops.

Therefore, the failure of the Battle of the Dao was a complete necessity. It did not matter how Jiang Wei's ability was. The main reason was that the Wei army was too powerful, and it was unparalleled. When Jiang Wei guarded Yong'an and Jiange, he completely threw all his trump cards in. When the Wei army launched an attack from Nanzhong, Jiang Wei had no strength to resist the Wei army's attack.
