The addition of the Flame Army outside the city provided long-range support for their comrades who climbed the walls, which caused heavy casualties to the defenders, many of whom did not dare to take the lead for fear of being shot by the Flame Army archers below.

And they can't do it if they don't take the lead, many of the Flame Army soldiers who are climbing on the city wall have already climbed to the top of the city wall, and they are about to climb over the wall, and those Flame Army soldiers on the siege ladder, if there is no special person to defend, they can quickly climb the city wall.

Cao Jun was stunned by this very cooperative style of play, and was confused for a while, and was soon seized by the besieging Flame Army to rush to the city.

"Kill-" The first flame sergeant who rushed up was not afraid of death, holding a small round shield in one hand and a Pu knife in the other hand is a burst of slashing, The somewhat flustered Cao army sergeants were killed to practice the day after tomorrow, until they were cut down by this flame army sergeant three people in a row, they reacted, rushed up together and trapped each other, and stabbed each other to death with a spear.

By this time, some of the other Flame Army sergeants had already climbed up and jumped into the crowd of defenders to kill.

At this moment, on the city wall of Xudu, its defense line is full of loopholes, everywhere is rushed up by the flame army sergeants, the security of the city defense is broken, and the defenders have also given up shooting arrows to the city, and under the leadership and command of the guards, they will go all out to eliminate these flame army sergeants who rushed to the city.

Xun Yu, Xu You, Hua Xin and others hid in the city tower and were seen that the city wall had become a battlefield of fighting, and they were shocked one by one, they still saw the first wave of siege by the besieging party and killed the city, the combat power of the Flame Army was so fierce and strong?

Although Xiahou Dun, the defender of the city, was already experienced in a hundred battles, he had never seen such a strong siege battle, and the soldiers of the Cao army under his command were attacked by the Flame Army before they even reacted, which was a big surprise to him, so that he was not mentally prepared.

"The order is for Yu Ban to transfer all the remaining men and horses to defend the city, if you don't do your best at this moment, I'm afraid that the defense line at the head of the city will not be guaranteed, go quickly!" Xiahoudun grabbed one of the soldiers and yelled, then threw him away and swung his sword to kill the enemy.

The battle on the city wall is becoming more and more intense, because there are more and more Flame Army soldiers who have climbed to the top of the city, and many sections of the city wall have been killed by the Flame Army soldiers.

Just when the city had become a battlefield of flesh and blood, under the city tower, dozens of Flame Army sergeants pushed a rushing cart covered with metal and iron sheets and rushed towards the city gate at the fastest speed.

There was a loud "boom", followed by the sound of wood exploding, and the city gate was hit by the rushing car with a loud noise, and the city gate was also hit by the head of the rushing car and cracked a hole.

The head of the rushing car was equipped with a quadrangular pointed cone, which was made of cast iron, which was extremely destructive, especially for this kind of wooden city gate, although the gate made of wood was very thick, but if the flaming military rushing car was allowed to crash down like this, I am afraid that it would not be long before the city gate was broken.

At the beginning, the defenders in the city gate cave only knew that the Flame Army was hitting the city gate with a ramming wood, and under the command of a school captain, more than 100 Cao troops crowded into the city gate hole to resist the city gate, preventing the Flame Army from knocking the city gate open.

But they didn't know that the large armor-piercing iron cone attached to the head of the striking wood, after hitting the wooden cone more than a dozen times in a row, the armor-piercing iron cone knocked a hole in the thick city gate at once.

The huge iron cone that penetrated into the city gate killed two sergeants at once, and the iron cone not only smashed their chests, but also broke out of their chests, leaving a large amount of blood from above, and the Cao army in the city gate cave was extremely frightened.

"Quick, the city gate can't stop the impact of this thing, you quickly move stones to block the city gate hole, if you don't block the city gate hole, sooner or later they will break the city gate, go quickly!"

"No!"

Several Flame Army sergeants ran to the edge of the city gate with spears, and before the car was pulled back to prepare for the collision, they put their spears into the barrel of the hole that was knocked open and stabbed them several times in a row, only to hear several terrible screams coming from the city gate cave in a row.

With a "boom-" sound, the rushing car hit the wood and loaded it on the city gate again, and a small crater was broken in different positions.

Waiting for the car to retreat, another Flame Sergeant next to him reached into the hole with a spear and stabbed several times in a row, and several screams came out.

"Plug the hole and board it!" A Cao Jun Du Bo shouted.

"Here comes the stones, here come the stones!" Someone shouted in the back, one by one the Cao Jun sergeants rushed over with stones, and the others got out of the way, but the sergeants who resisted the city gate could not completely get out of the way, otherwise the inside would not resist, and the outside rush car would soon knock down the city gate.

This siege war was completely a bloody battle, originally a good defense battle, with the protection of the city wall, the soldiers of the Cao army should have been able to sit back and relax, but they did not know enough about the Flame Army, and underestimated their combat power, battlefield quality, organization and execution ability.

This lack of understanding and psychological preparation caused them unbearable consequences, and the bloody battle on the city wall lasted until the afternoon, which was also the Cao army continued to increase troops on the city wall to persevere.

"Dangdangdang······" The gong sounded, and then the signal for retreat.

The soldiers of the Flame Army, who were still fighting fiercely with the defenders just now, did not love to fight, and retreated one after another, sliding down the siege ladder one after another, the action was too sharp, and it looked like they had been trained for a long time, and without long-term training, ordinary people could not have such courage to slide down.

The Flame Army soldiers left with the siege ladder, and if they didn't, the defenders would definitely take it.

As soon as the flame army sergeants on the city wall withdrew, the surviving Cao army sergeants dropped their weapons one by one and sat on the ground of the city wall and gasped violently.

The tragedy of today's battle to defend the city refreshed the cognition of everyone in Cao's army.

Xun Yu and other civil officials walked out of the city tower and saw that the city wall was already covered with corpses, almost no place to stay, and all the corpses were covered with blood, and the blood had coagulated over and over again.

The one-eyed dragon Xiahoudun was covered in blood, both his own, his sergeants, and more of the Flame Army sergeants.

"Throw all these enemy corpses down, throw them farther away, don't throw them at the foot of the city wall!" Xiahoudun gave orders to the seated sergeants.

The sergeants complained, but reluctantly got up to work.
