A few days before Lü Meng's army arrived at the city of Bajun, Zhang Ren also received an order from Liu Zhang to lead a part of his men to the rear of Mianzhu and flank Cao's army with Yan Yan.

Zhang Ren also did not expect that Cao Jun would send troops to steal the 'yin' peace again, and he was quite surprised when he heard the news. Zhang Ren considered that the Cao army, which had survived the 'yin' peace, had good combat strength, and in order not to repeat the mistake of Leng Bao, he finally decided to personally lead the army to exterminate the Cao army. After handing over the defense of Jiange Pass to Wu Yi, Zhang Ren immediately rushed to Mianzhu with 5,000 men and horses.

Wu Yi is also a lieutenant general of Shu, and Zhang appointed him to guard the pass tightly, and he must not go out of the pass to fight with Cao's army. Considering Wu Yi's 'sexuality' calmness, I don't think there will be anything wrong.

Zhang Ren's marching route was the same as the previous route of Lengbao, taking Zitong to the north of Mianzhu City, and also recovering Fucheng by the way. In terms of generals, Zhang Ren is far better than Leng Bud several times, naturally he will not make mistakes easily, his military camp camp 'door' is separated by a layer of horses, and the garrison in the camp is arranged quite tightly, such as Gao Shun risking to rob the camp, even if he is leading the world's 'elite' division, Zhang Ren is also confident that it will not return.

When he learned that Zhang Renqin led a group of men and horses to appear in the north of Mianzhu City, Gao Shun, who was sitting in Mianzhu City, couldn't help but show his face 'worried'.

originally thought that he was about to conquer Chengdu, but unexpectedly, the situation took a turn for the worse, Yan Yan's reinforcements arrived not to talk about it, and Zhang Ren also appeared behind Mianzhu with a detachment of men. If Yan Yan and Zhang Ren attack the two 'gates' in the north and south of Mianzhu at the same time, it will be quite difficult for Mianzhu City to defend it.

For Zhang Ren, Gao Shun naturally knows him very well, his people are both wise and brave, and he is 'proficient' in military strategy, which can be described as the first general in Yizhou, and he is by no means comparable to Leng Bao.

And speaking of which, Zhang Ren is still Zhao Yun's senior brother, of course, Gao Shun will not have any extravagant hopes for Zhao Yun to talk about Zhang Ren. Zhang Renzhi's loyalty, in the entire late Han Dynasty and the Three Kingdoms era, can also be called one of the best, in history would rather die than Liu Bei, known as a model of loyal ministers.

As the saying goes, whatever you are afraid of comes, Zhang Ren and Yan Yan really launched an attack on Mianzhu at the same time with a tacit understanding.

Yan Yan's 4,000 men attacked the Mianzhu South 'Gate', and Zhang Ren's 5,000 men attacked the Mianzhu North 'Gate'. As a result, Gao Shun had to disperse his forces to two city 'gates' to guard.

Cao's army originally had only 3,000 men, and with such a division of troops, there were only 1,000 or hundreds of people left in each place for defense, and the pressure it faced was quite great.

The Yizhou army attacked the city very hard, and they knew that as long as the enemy army occupying Mianzhu City was defeated, the invasion of the Cao army this time would end in complete failure, so the soldiers were desperate, even if they died, they were not afraid.

Zhao Yun's face was solemn, and he commanded his assault battalion soldiers to fight hard to kill the enemy soldiers who rushed to the city.

It's ironic to think that a few days ago, he led his soldiers to attack the city with a ladder below, but now he is standing on top of the city to defend it.

Due to the difference in the number of enemy troops at the 'gates' of the north and south cities, the guarding strength of Cao's army was naturally different, Zhao Yun led his 1,700 assault battalion sergeants to guard the north 'gate', while Gao Shun led 1,000 soldiers from his camp to guard the south 'gate'.

In addition, the assault battalion and the trap camp each 'drawn' a hundred soldiers were transferred to watch the original surrender of Mianzhu. And the leaders of these 200 guards were also ordered to kill them if they made the slightest move!

Although Gao Shun didn't want to kill indiscriminately, but now the situation is urgent, if those troops take the opportunity to make a 'mess', the consequences will be really unimaginable.

Although Gao Shun originally didn't expect these troops to be of any use when attacking Shu, but now it has become an unknown hidden danger, and even weakens the strength of the city to see those surrendered troops, which is also what Gao Shun did not expect when he surrendered a few days ago.

The soldiers of Yizhou knew that as long as they recaptured Mianzhu, they would be able to successfully defend Yizhou, and the soldiers of the Cao army naturally knew what it would mean once the city was lost. Therefore, the Yizhou soldiers desperately attacked the city, and the Cao army sergeant also swore to resist, even if the 'chest' was pierced by the enemy soldiers who climbed the ladder with spears, they had to use all the remaining strength of their bodies to push the opponent off the city wall before swallowing their last breath.

Zhao Yun, as the main general, was the first soldier, and at this time, he had killed more than thirty enemy soldiers, and the silver armor he wore was gradually soaked red with blood.

Although the soldiers of the Yizhou army tried their best to attack the city as if they were not dying, the besieging side was in a disadvantageous position after all, and the Cao army was also at home when they killed the enemy, so the offensive of the Yizhou army in the north 'gate' was temporarily blocked, and no enemy soldiers climbed the city for a period of time, and Zhao Yun was able to take a breath.

Zhao Yun set his eyes on the middle of the Yizhou army's military formation under the city, although the distance was far away, but Zhao Yun's eyesight was very good, and he still saw Zhang Ren, the commander of the enemy army sitting in the center of the military formation.

Although looking down at the city, he couldn't see the specific appearance of the other party, and could only see a general outline, but Zhao Yun also knew that the person who commanded the soldiers of the Yizhou Army to attack the city in the center of the army array was Zhang Ren, the commander of the Yizhou Army, and he was also his senior brother with the 'door'.

Cannibalism with the 'door', although it is helpless in this 'chaotic' world, Zhao Yun still feels a trace of sadness.

Although when his mentor Tong Yuan accepted him as an apprentice, his two senior brothers had already become teachers, and they had never met each other, let alone gotten along, but before he became a teacher, Tong Yuan still did not forget to take care of himself, so that he could support each other with the two senior brothers as much as possible in the future, create great things in the 'troubled' world, and protect the peace of the people.

However, his eldest brother Zhang Xiu was killed by his colleague Dian Wei as early as when the princes were fighting for Dong. But can he resent Dian Wei because of this? At that time, Zhang Xiu and Gao Shun, whose martial arts were not yet 'refined' and pure, were about to kill Gao Shun, if Dian Wei didn't make a move, it would be Gao Shun who would be killed.

Although Zhang Xiu and Zhao Yun have a brotherhood, after all, the two have never met and never 'communicated', and in Cao Ying, Zhao Yun is indeed 'friendly' with Gao Shun now. It is a pity that his senior brother was killed by his colleagues, but is it appropriate for his colleagues to be killed?

Speaking of which, we can only blame this 'chaotic' world.
