Xue Rengui's attack did not stop for a day, and the head of Liyang City was already in pain, and the walls were full of mud. If you're not careful, you'll fall to the ground.

And Xue Rengui didn't just throw it into the city, but also wanted to throw it under the city. After more than ten days, a mound of earth as high as three zhang high had been piled up under the city.

Lü Meng organized the well to cover outside the city to prevent Cao Jun from climbing to the city wall, and Wei Yan carried a basket of soil on his back and kept piling up the mound of earth.

After Cao Ren learned about it, he immediately led his troops to the city wall to block it, but the enemy outside the city had strong bows and crossbows, and Cao Ren could only lead people to fight back while dodging. But on top of the mound, Zhang Yijun had already used a wooden plank as a shield to cover his back.

This is a mound of earth armor made by craftsmen in the workshop. One or two long sticks were laid on a wooden board at one end and a stone tied to the other, and placed on top of the mound, so that they could be protected against arrows without the need for human use.

In Liyang City, Cao Ren didn't have much to do about it. The planks stood outside the city, and they were out of reach with forks.

Cao Ren found Cao Xiu and said, "The enemy's plank is too much of a hindrance, and the plank must be destroyed." ”

"I'm going to get people ready for rockets." Cao Xiu said.

"It must be fast!" Cao Ren urged.

Cao Xiu nodded immediately, and in less than an hour, he had finished the rocket and prepared the canister for oil. After getting ready, Cao Xiu went up to the city wall, led people to drop the oil pipe on the wooden plank, and then shot it with a rocket. A raging fire immediately ignited on the plank.

When Wei Yan saw that the wooden plank was ignited, he immediately shouted: "Hurry up, take advantage of the flames to block the view of the city, and pour more earth."

Even if there is oil, burning the planks is not a matter of time and a half, and it takes a quarter of an hour. And during the burning period, the smoke rises, and it becomes unclear to look inside the castle to the outside of the castle. Taking advantage of this time, Wei Yan took the transport up to a foot of soil.

The flames were almost burning, and Wei Yan led people to transport the mound of earth armor, and lifted the previous mound of earth armor directly to the city to make use of it. As soon as the new mound armor was put on, it was ignited by Cao Xiu again. Wei Yanyou took advantage of this time to pile up a foot of soil.

In this way, the mound was piled up foot by foot, and in only ten days, the mound was piled up to the edge of the city wall.

Xue Rengui knew that it was time to attack, so he let Wei Yan and Ma Chao take the vanguard and pounce on the mound with a wooden ladder. Wei Yan and Ma Chao led the army to climb first, and after laying the wooden planks, they rushed to the city wall with a shield and a sword.

Cao Ren, Guo Huai, Cao Xiu and others had already waited on the city wall with their soldiers, they had already completed the military formation, and they were waiting to attack the city.

Lü Meng commanded the well railing and the ballista carts, and after seeing the city wall gathering, he immediately ordered to shoot at the city.

Lu Meng was personally beating the drum, and as soon as the dense drums sounded, Wei Yan and Ma Chao, who were besieging the city, immediately led people to squat on the spot, and then held the shield above their heads to prevent accidental injury.

Cao Ren and Cao Xiu were preparing to roll the wood and stones, and wanted to smash them down the mound. They had smashed a lot of them before, but the mound was not solid and the slope was not enough, so the rolling wood and stones did not go far before they fell into the mound. So they were ready to smash the enemy after getting closer, but suddenly the enemy drums sounded, and all the besiegers crouched down?

A trace of bad feeling flashed in Cao Ren's heart, and just as he was about to shout, he saw countless arrows flying. "Dodge the arrows!"

Without Cao Ren's size, these soldiers also saw the arrows, and subconsciously began to hide. But there were too many soldiers in the city, and many of them were still shot.

After three rounds of arrows, Wei Yan and Ma Chao stood up and rushed to the city. This was agreed before, and the cover would only shoot three rounds of arrows, and the rest would be up to them. However, three rounds of arrows were enough, Wei Yan and Ma Chao directly threw the plank ladder behind them forward, stepped on it and went straight to the city wall. There were a lot of rolling wooden stones on the side of the city wall, and the two stepped on the rolling wooden stones, crossed the female wall, and rushed to the city wall.

"Kill!" When Ma Chao saw Cao Bing, he immediately became ruthless, cut down one with one knife, kicked one away, and successfully gained a firm foothold on the city wall. But he didn't want to stick to it, but killed him directly, he was never a defensive person.

"Ma Mengqi is here!" Ma Chao shouted loudly: "Cao Ren will die quickly!" ”

Ma Chao shouted loudly, attracting the attention of most of the Cao soldiers, and many Cao soldiers rushed towards him, wanting to kill him. Although Ma Chao is famous, it was seven or eight years ago, and now Ma Chao's reputation is no longer there, and it is not as famous as Xue Rengui and others. Cao Bing was not afraid of him, but wanted to kill him for meritorious service.

There were a lot of people around, and Ma Chao was also a little difficult to parry.

Fortunately, at this time, Wei Yan had gathered more than a dozen soldiers, rushed up to help Ma Chao repel the enemy soldiers, and rescued him.

Ma Chao was rescued, rested for a while, and then said to Wei Yan: "You come to occupy the city wall, and I will kill the enemy general." ”

Wei Yan nodded and gave Ma Chao a part of the soldiers. Ma Chao jumped on the women's wall, glanced around, and saw Cao Xiu coming towards this side at a glance. Ma Chao knew Cao Xiu, and he remembered all the surnames Cao vividly. Jumping down from the women's wall, Ma Chao led people to kill him.

Cao Xiu also discovered Ma Chao and immediately ordered the soldiers to come over and strangle him. He has also fought a lot of battles with Zhang Yijun, so he naturally knows Zhang Yijun's characteristics. He did not fight with Ma Chao in close combat, but attacked from afar with a spear.

What Ma Chao is not afraid of is the spear, he is leading the cavalry, if he didn't have the skill to deal with the spear, he would have died I don't know how many times. The ring-headed knife in Ma Chao's hand jumped under the spear, and then took the opportunity to drill under the spear with a shield, Ma Chao rushed to the vicinity of the spearman, and the ring-headed knife slashed continuously, breaking the spear array.

Cao Xiu didn't expect Ma Chao to rush over like this, and hurriedly greeted him, looking at Ma Chao with a ring of swords. Ma Chao used a shield to fly the ring head knife, and a knife was inserted into Cao Xiu's abdomen.

Cao Xiu lost all the strength in his body and fell to the ground, he didn't expect that he would die like this.

Ma Chao cut off Cao Xiu's head, threw it into the city, and shouted: "Cao Ren, come and die!" ”

Cao Xiu's death made changes on the city wall, Cao Bing saw Ma Chao's bravery, and suddenly woke up, this is Ma Chao! Ma Chao, who used to be in the pass!

The morale of the defenders plummeted, and some even began to flee. Wei Yan successfully captured the city walls and then launched an attack on the city. The crossbowmen went up the city wall one after another and attacked Cao's soldiers from a high position. Cao Bing lost the city wall as if he was not Zhang Yijun's opponent at all, and Cao Ren had no choice but to evacuate Liyang and retreat north to Neihuang.
