On the city wall of Mianzhu, Li Yanzheng worked hard to command the soldiers to fight.

Without warning, Cao's army suddenly launched an attack on Mianzhu City. Although Mianzhu City has been in a state of preparation, for more than ten days, Gao Shun and his army have been cowering in Fucheng without the slightest movement, so that the soldiers of Mianzhu City will inevitably be a little lax, thinking that Cao's army does not have the courage to attack the city.

Li Yan was also a little puzzled, the number of soldiers in the Cao army was not very many, and it was supposed to preserve every ounce of strength, so how could he suddenly launch an attack.

You must know that if Cao's army fails to attack the city, but suffers losses, then there is only one way to fail.

But in any case, since the other party has already attacked, then there is no need to think about the other party, just do your best to defend yourself.

Li Yan believed that as long as he repelled this 'wave' attack of the Cao army, even if the Cao army was completely destroyed, it could no longer form any threat, and could only gradually annihilate in front of his eyes.

Arrows continued to 'shoot' at the bottom of the city, and the city's defense equipment such as sasswood and rolling stones also continued to spill down, causing a lot of damage to Gao Shun and Zhao Yun's army.

After all, Fucheng is a small city, and there are not many siege equipment in the city, even the most basic cloud car, which brings a lot of difficulty to Gao Shun's siege.

It is also thanks to the arrival of Zhao Yun's reinforcements, the number of Cao's army is two and a half times that of the Mianzhu defenders, otherwise Gao Shun will not consider attacking the city so far.

But Rao is like this, there are still many Cao soldiers who died under the Mianzhu city wall, these are the 'elite' soldiers in the trapped camp and the assault battalion, but now they are killed by the defenders of Mianzhu City one after another with bows and arrows or wood and stones.

"Hold on! As long as you hold on for a while, the enemy army will be powerless! Li Yan shouted loudly on the city wall.

Up to this moment, Li Yan had not worried about the defense of Mianzhu City, and in his opinion, Cao Jun's reckless siege was nothing more than sending him to death.

Watching one corpse after another thrown down from the city wall, Gao Shun and Zhao Yun were both heartbroken, you must know that these are the most 'elite' soldiers in the Cao army, and every sacrifice is a huge loss.

However, there is no way, siege warfare is not as good as flat field warfare, and it is destined to use human lives to pile up a road to the city wall in the early stage.

And whether it is the trapped camp or the assault battalion, a lot of sacrifices have been paid before this, especially Gao Shun's trapped camp, most of the dead and wounded before attacking Mianzhu. At this point, Mianzhu must be captured.

As time passed, Cao Jun had left nearly 400 corpses under Mianzhu City. But the sacrifice was not unrewarded, and finally someone took the lead in climbing the city.

The first to climb the head of Mianzhu City was a military commander in the trapped camp, but before this military commander stepped on the top of the city with both feet, he was stabbed in the body by three spears at the same time, and fell straight backwards.

But in any case, this military commander has already made a start, so that the Cao soldiers below further see the hope of capturing Mianzhu.

The soldiers trapped in the camp and the assault battalion became more and more courageous, and more and more soldiers set foot on the head of Mianzhu City. Although the Mianzhu defenders were able to catch up with one or two Cao soldiers, when four or five, seven or eight Cao soldiers appeared in front of them one after another, these guards couldn't help but feel a little panicked.

At this time, Li Yan, who was the general of Mianzhu, also realized that something was wrong.

Gao Shun chose the time to launch the siege in the early morning when the sun had just risen, and I have to say that this time was just right. Li Yan judged that Cao Jun would not dare to attack the city head-on when he was cornered, so he might launch a night attack, so Li Yan would personally inspect the city wall every night, and then go back to the palace before dawn to sleep for a while. When Gao Shun led the army to attack, it was when General Li Yan woke up, and when he got the news and hurried to the city wall, the siege of Cao's army had already begun. The soldiers of the Cao army were constantly pouring towards the Mianzhu city wall, and Li Yan couldn't judge the number of opponents for a while.

If Li Yan had observed the Cao army's military formation in advance before the Cao army attacked the city, it would have been easy to judge the approximate number of the opponent. Although the number of Cao's army is far greater than that of the defenders in Mianzhu City, if you can see the details in advance, you can make some corresponding arrangements.

Although the fact that one's own side is superior in numbers will not change, the results of caution and lack of preparation can vary greatly.

Now, when Li Yan felt that the number of Cao troops was more than the number in the intelligence, the Cao army had already vaguely suppressed the city wall.

Li Yan's face became very bad, although he didn't know how the enemy came out, but he saw that the Mianzhu defenders were gradually unable to hold on. If the battle continues like this, it is only a matter of time before Mianzhu loses ground, and it will not be too late.

Once Mianzhu is lost...... Li Yan didn't dare to imagine what would happen next.

Although there were still 2,500 defenders within the range, once Cao's army directly approached the city of Chengdu, Li Yan didn't know how much war spirit the defenders in the city would have.

The most important thing is that Liu Zhang's 'sex' character Li Yan couldn't be clearer, if Cao Jun really appeared outside Chengdu, then even if Chengdu had the strength to fight, Liu Zhang would directly choose to open the 'door' and surrender under fear.

In a hurry, Li Yan lifted his sword and went into battle in person.

No matter what, Cao Jun must be held back outside this Mianzhu City!
