Jiang Wei, who was retreating to Nan'an, was also thinking about this issue. After retreating from Wudao to Nan'an, he originally thought that the Wei army would pursue him relentlessly and would continue to fight fiercely next time, but unexpectedly, the Wei army gave up the pursuit and turned to attack and defend the empty Jiangzhou.

Of course, Jiang Wei's loss would not surprise Jiang Wei. After all, the Shu army did not deploy defensive forces in Jiangzhou. Once the Wei army attacked Jiangzhou, Jiangzhou would change hands, which would be destined.

Jiangzhou is an important town in the eastern part of Shu Kingdom, and its status is second only to Chengdu. If Shu Kingdom had not been short of military strength, it would have definitely not given up Jiangzhou easily.

Instead of attacking Chengdu directly, Yang Hu first attacked Jiangzhou, which had empty defense. On the surface, he looked far and wide. However, after attacking Jiangzhou, the Wei army could form a front-end and back attack on Yong'an's Shu army.

It seems that the Wei army launched an attack from Nanzhong, not to plan to attack Chengdu directly, but to encircle the retreat of the Yong'an Shu army, trying to take down Yong'an, and introduce the Wei army, which was blocked by the Shu army from Yong'an, into Shuzhong.

The Wei army not only wanted to capture Chengdu and destroy the Shu Han Dynasty, but also occupied all the land of Shu, conquered all the population of Shu, and killed people to kill their hearts. This was the case.

After Jiangzhou fell, the situation became even more severe for Shu Kingdom. In the final analysis, the army deployed by Cao Liang in Jiaozhou played a crucial role. The defense on the southern front was indeed the weakest link of Shu Kingdom. The Wei army started from this weak link, and Jiang Wei was unable to defend.

In fact, this is also a helpless move. Even if Jiang Wei thinks about it, he will face the embarrassment of no troops. After all, the defenses of Hanzhong and Yong'an have already emptied almost all the troops of Shu. It is quite difficult for Jiang Wei to dispatch troops to Nanzhong that can resist the attack of the Wei army, and it is almost impossible to achieve.

Therefore, this failure of Ye Dao is not an occasional thing. In Jiang Wei's life experience, there are too many such failures, countless.

However, this failure made Jiang Wei feel a sense of powerlessness in his heart. To be honest, the Wei army almost did not use any conspiracy in this attack, just a crushing force, pulling the two wings and then breaking through in the middle. After this battle, the Shu army was completely defeated, and there was no chance of turning the tables.

This gap in strength made Jiang Wei almost desperate.

In previous Northern Expeditions, although there were wins and losses, Jiang Wei never lost confidence. Wherever he fell, he would get up and never give up. This is Jiang Wei's life creed.

But this time, Jiang Wei felt deep setbacks and despair. Jiang Wei failed in the past, but he would tell himself that there was another time, and he would definitely make a comeback next time and avenge his previous shame. But now, Jiang Wei can no longer feel the existence of hope.

However, despite the despair, Jiang Wei is still the one who will never give up easily. Even though the situation is so difficult, Jiang Wei is still thinking about how to deal with the battle and how to protect Shu Han from the destruction of the country.

The fall of Jiangzhou means the fall of Yong'an, because Jiang Wei knew very well that after losing logistics supplies, Yong'an could last for at most three months, and the prerequisite was that the Wei army that captured Jiangzhou would not attack Yong'an's Shu army. After three months, the Yong'an defenders would completely collapse due to the exhaustion of food and grass, and Yong'an would not defeat himself.

Of course this is the most optimistic situation. In fact, the Wei army from Xiling would not stop the attack at all. When Jiang Wei was still in charge of Yong'an, it was already very difficult to defend against the Wei army attacking from Xiling. Jiang Wei and Sima Lun drew 60,000 troops from Yong'an one after another, and more than half of the troops were drawn. This impact was so great for Yong'an.

However, the Wei army's offensive forces increased and the other was declining. The original stalemate situation of Yong'an naturally changed accordingly.

Of course, if it were just the enemy of Xiling, Lu Kang might be able to hold on with his ability, but Jiangzhou's defeat put Yong'an in a dilemma of being attacked from both sides. In this situation, even if Lu Kang could fight, he would probably be unable to resist.

At this time, Jiang Wei needed to make a decision. Since the Wei army had already attacked Shu from Nanzhong, the existence of the Yong'an defense line had no meaning. At this time, blindly defending to the death is the most stupid behavior.

If more than 50,000 defenders in Yong'an were completely wiped out by the Wei army, it would be even worse for Shu Kingdom in a storm. Therefore, the only way to do this is to shrink its troops, preserve its strength, concentrate the remaining troops around Chengdu, and fight to the death with the Wei army to defend Chengdu and the country.

In fact, for the Shu Han court, there was no way out at this moment. The Wei army launched an attack from the three sides of the north and southeast. In these three directions, the Shu Kingdom could no longer break through.

The only direction that the Wei army did not have a siege was the west, but the west was a deserted snow-capped plateau. From Chengdu west, there were towering snowy mountains. There were deserted and the natural conditions were extremely harsh. Even if Shu Kingdom fled there, it would either be frozen to death or starved to death, and there was no way to live.

Therefore, Chengdu is a dead end to the west, and no one will consider the issue of retreating west. Since we cannot go, there are only two ways of war and surrender. Perhaps some people in the Shu Han Dynasty couldn't wait to surrender, but in Jiang Wei's dictionary of life, the word "submission" would never appear.

Although Jiang Wei was also from a Wei family, he never regarded himself as a Wei family. Instead, he was loyal to the Han family throughout his life and took it as his responsibility to restore the Han family's mountains. Now that the situation is in danger, Jiang Wei is still loyal and determined.

With the current situation, it is impossible to expel the Wei army from Yizhou. The only way Jiang Wei can do is to protect the Shu Han court as much as possible. Although no one knows how long this court can survive, for Jiang Wei, as long as he has a breath, he cannot sit idly by and watch the Shu Han fall.

After Jiang Wei retreated to Nan'an, he began to plan a new defensive strategy, which is to radiate a distance of 100 miles south to east to north with Chengdu as the center, and build a semicircular defensive position to resist the Wei army's attack.

Whether Chengdu can be defended will ultimately depend on whether the outer defensive positions can be defended. This battle for Chengdu will be the last decisive battle between Wei and Shu. If you win, you will live, and if you lose, you will die. Jiang Wei has no way out.
