Historically, after Deng Ai's 'Yin' was pacified, the defenders of Jiangyou and Fucheng were afraid and surrendered without a fight, so that Deng Ai's troops were not consumed too much. After that, Deng Ai and Zhuge Zhan father and son fought in Mianzhu, won the battle, and Zhuge Zhan and his son died. Liu Chan saw that the general trend had gone, so he surrendered to Wei.

And now, Gao Shun first fought a tragic battle with the ambush soldiers in Yizhou at the exit of the 'Yin' Ping Road, and then lost hundreds of people when attacking Fucheng, so that Gao Shun had no advantage in terms of strength when attacking Mianzhu.

For Gao Shun, it was even more unfortunate that the general stationed in Mianzhu at this time was Li Yan. Li Yan, a famous general, can fight well, and is both wise and brave. When Deng Ai attacked Mianzhu, although Zhuge Zhan, the Shu general he faced, was the son of Zhuge Liang, he did not inherit Zhuge Liang's amazing talent, and his military talent was far inferior to Li Yan. With Li Yan guarding Mianzhu, he naturally would not let Gao Shun easily break through.

It can be said that the situation Gao Shun is facing at the moment is completely different from Deng Ai, and the difficulty level has really increased several times.

Gao Shun has now realized that he still thought things too simple at the beginning, thinking that Deng Ai could successfully destroy Shu and he could do it, but along the way, he suffered repeated setbacks.

Deng Ai successfully destroyed Shu, I have to say that there is his own luck component, but Gao Shun doesn't seem to have this good luck.

Seeing that Mianzhu was well-defended, Gao Shun did not dare to rashly launch an offensive, after all, one of the soldiers under his command died now, and if he failed to break through the city, but lost hundreds of people, then his situation would be even more difficult.

If the battlefield was elsewhere, Gao Shun estimated that he would have retreated long ago, after all, Mianzhu was hopeless to conquer, and it became a luxury to continue to advance, and it was basically impossible to achieve victory.

But now, Gao Shun is in a desperate situation, even if he wants to retreat, where can he retreat, it is not easy for him to lead the army through the 'yin' peace, but there is no possibility of returning the same way.

It can be said that Gao Shun's trapped camp has lost all retreats since the moment it rolled down from the cliff of 'Yin' Ping, and once it is unable to move forward, it is only a dead end to wait for Gao Shun and his trapped camp.

Gao Shun could only temporarily station the trapped camp in Fucheng, but this was not a long-term solution, and it was difficult to solve the matter of grain and grass alone. When Gao Shun attacked the city, the defenders of Fucheng saw that the city was about to be lost, and they had set fire to the grain, although Gao Shun tried his best to save the food after breaking the city, but most of the grain and grass were still burned. Although the number of people trapped in the camp is only 1,500, the grain and grass in the city are even more pitiful, and the remaining grain and grass in the granary of Fucheng can only last for six or seven days. And trapped in the lonely city, in addition to food and grass, all kinds of other troubles and difficulties are also endless.

But Gao Shun had no other way, he had completely lost his ground.

In fact, as far as the current situation is concerned, withdrawing Jiangyou is a good choice. There is still a lot of surplus grain in Jiangyou City, which can support this trapped camp for at least more than a month. It's a pity that Gao Shun's mood is a little 'disordered' at the moment, and he can't take this into account.

In addition, withdrawing Jiangyou from Fucheng means that Gao Shun will completely give up his plan to attack Chengdu. Moreover, even if Gao Shun withdrew to Jiangyou, the Yizhou army could be transferred from Mianzhu to Fucheng, and the dilemma faced by the trapped camp did not change substantively except for getting more food.

The current trapped camp has completely become a lone army, a lone army trapped in a desperate situation, a lone army that may be wiped out if you are not careful.

After learning that there was an army to survive the 'yin' peace, and Liankejiangyou and Fucheng, Zhang Ren also reacted quickly.

Zhang Ren immediately ordered Leng Bao to lead 5,000 men and horses back to Chengdu.

Zhang Ren also understands the reality of Cao Jun outside the Sword Pavilion Pass, at least Zhang Ren knows very well that the number of Cao Jun stationed outside the Sword Pavilion is definitely not much, and it is nothing to allocate these 5,000 people by himself.

Even if there were only 20,000 people in the Sword Pavilion Pass, Zhang Ren dared to ensure that he would not lose it, not to mention that after Leng Bao led the army away, there were still 40,000 Yizhou Army soldiers left in the Sword Pavilion.

Unless a miracle comes down from heaven, Cao Jun has no chance of breaking the barrier.

As for the Cao army that survived the 'yin' level, Zhang Ren did not have the slightest worry. Although I don't know how the other party won the 'engagement' battle with the ambush soldiers, and Liankejiangyou and Fucheng, Zhang Ren is sure that if such a result can be achieved, the Cao army must also pay a great price. What's more, in Chengdu, there are generals like Li Yan who are good at fighting.

Leng Bao led 5,000 people back to Chengdu, Chengdu will be safe and sound, and it is even possible to wipe out that strange army.

From Zhang Ren's point of view, this time Cao Jun sent troops in a hurry, and there was nothing too fearful.

Although the army in Yizhou, in terms of number and combat power, could not compete with the Cao army, which had conquered most of the country, as far as this war was concerned, Zhang Ren felt that there was nothing in Yizhou that would lead to defeat.

What we need to worry about now is not the Cao army in front of us, but the next step of Cao's revenge after defeating this Cao army, but that is something that needs to be considered after this war is over.
