The Tang army formed a good formation but did not attack. The soldiers of the Tang army were not surprised at all, as if they knew what would happen, they were all waiting quietly.
Not far away, Luo Zhang checked the artillery again and immediately ordered the ammunition to be loaded.
What was loaded this time was no longer gunpowder bullets, but solid iron bullets. Luo Zhang's purpose was not to kill the enemy, but to blow down the city wall.
Gunpowder bullets will not have the effect of demolishing the city wall. Only solid iron bullets will hit the city wall like a heavy hammer after being launched.
One round is twenty solid iron bullets, like twenty heavy hammers hitting a city wall. According to Luo Zhang's calculations, if it takes three to four rounds, the city wall may not be able to hold on and be blown down by him. At that time, it was time for the Tang army to launch a charge.
After learning that the army was already in position and waiting for him to take action, Luo Zhang did not hesitate at all and immediately ordered the artillery fire.
"Boom boom boom!!"
Waves of roaring sounds resounded across the ground, and twenty artillery fires made the ground feel a faint earthquake. Not only the Gaoguli people on the city wall of Liaodong County felt the earthquake, but the Tang Army not far away felt the earthquake even more strongly.
There was a look of horror on everyone's face, as if they were facing the mighty power of Heaven.
However, the scene that shocked them even more was yet to come.
I saw dark iron balls hitting the right city wall of Liaodong County at extremely fast speeds.
Sure enough, it was like a giant hammer hitting the city wall.
When the iron ball hit the city wall, the Gaoguli soldiers on the wall suddenly lost their footing, staggered around, and fell to the ground.
Cui Dunshi, who had been observing, immediately changed his face. The bad premonition finally became a reality. Even when he was standing on the tower, he was almost knocked down by the shock. If he hadn't been supported by someone, he might have fallen down. Already made a fool of himself.
"Quick, look what happened, quick!" Cui Dunshi pushed away the soldiers who were supporting him and roared at the surrounding generals.
Everyone did not dare to neglect, and immediately headed towards the right wall where the roaring sound came from.
Before these generals arrived, a guard ran over with a pale face.
"Cui Shuai, it's not good, something serious is going to happen!" Du Wei said in a panic.
"Stop talking nonsense, what's going on?" Cui Dunshi scolded.
"The city wall... the city wall is cracked!!" Du Wei said tremblingly.
"What? What did you say? Why is the city wall cracked? Tell me clearly!" Cui Dunshi grabbed the guard by his collar and raised it in front of him and asked.
But before the guards could answer, there was another tremor of the earth. This time, without the guards having to say anything, Cui Dunshi had already seen rubble falling from the west city wall, and the Gaoguli soldiers on the wall They ran towards the middle wall like headless flies, and some were unsteady on their feet and fell off the wall.
This scene made everyone widen their eyes and look at this scene in disbelief.
"This..." Cui Dunshi breathed a little quickly and even swallowed his saliva. Not to mention the generals were dumbfounded, even he was frightened when he saw this scene.
When Luo Zhang's shells fired for the third time, Cui Dunshi finally saw the black iron bullets piercing the sky and bombarding the west city wall.
But this was the last time he saw it, because the city wall collapsed after the third bombardment.
A large number of soldiers fell from the city wall, and the spare rolling logs and stones also fell to the ground under the collapse.
Seeing the collapse of the western wall of Liaodong County, the Tang Army was happiest.
The soldiers of the Tang Army burst out laughing with joy. At Li Jing's order, the army rushed towards the collapsed city wall.
On the city wall, Cui Dunshi still didn't come to his senses when he saw the incoming Tang army. He just stared blankly at the originally solid city wall to the west, which collapsed at this time.
"This is impossible, this is impossible, how could the city wall collapse, how could it collapse!" Cui Dunshi muttered to himself. Not only was he saying this, but all the generals were also muttering to themselves.
"Cui Shuai, Tang Jun, Tang Jun is coming!" A general who was still awake shouted at Cui Dunshi, which brought Cui Dunshi back to reality.
"Quickly, shoot the arrow quickly, shoot for me, don't let Tang Jun rush up, hurry up!!!"
Cui Dunshi, who came back to his senses, hurriedly ordered, but even if the arrows rained down on the Tang army like a waterfall, it could not stop the Tang army's advance.
Although some unfortunate Tang soldiers fell to the ground due to arrows, more of them rushed through the rain of arrows, reached the western city wall, and rushed into Liaodong County from the ruins.
Seeing the army rushing into Liaodong County, Luo Zhang was relieved. The rest of the matter had nothing to do with him, and Liaodong County was already in his pocket, no different from what he had arranged.
