Twenty huge stones flew towards the city wall east of Tongguan. Some hit the walls of the city wall, some crossed the city head and fell into the city. Only some happened to fall on the walls of the city wall.

The stones shattered the bricks on the wall with huge kinetic energy, revealing the rammed earth wall inside. Whenever the stones hit the city wall, the soldiers guarding the city at the top of the city could feel the floor on the city trembling. However, these powerful flying stones did not cause actual casualties except for psychologically oppressing the soldiers guarding the city.

After several rounds of flying stone attacks, the defenders at the city wall knew that these catapults had ended their skills and were no longer afraid. The thousands of soldiers of Cao's army who operated the catapults were already out of breath. During the entire flying stone attack, only one of the soldiers of Lu Bu's army at the city wall was smashed into blood and blood by the huge rocks.

At this time, the real siege operation had begun. More than twenty tower vehicles were launched from behind the Cao army formation one after another, and a huge siege rusher also slowly came from the middle of the army formation. The inner side of the city of Tongguan was filled with soldiers holding swords and guns, and in the front row were hundreds of crossbowmen. The three thousand soldiers stationed in Tongguan were divided into three parts, one defending the west wall and the other defending the east wall. The last thousand were placed in the city of Guan as preparation.

With the order of Cheng Lian, the crossbowman stepped forward and shot the arrows in his hand at the Cao army, which were swarming with siege equipment. The soldiers of the Cao army raised their shields and continued to move the rushing carts and tower cars to the city wall. When Cheng Lian saw that the arrows had no effect, he ordered the crossbow shooting to be suspended and prepared to roll the wood and rock attack.

When Cao's rushing car arrived at the Tongguan city gate, the wooden rocks fell like a storm. The Cao's soldiers holding the shield could not withstand it, and they were injured and fell to the ground. Some of the shields were not cracked, but their arms holding the shield were broken first. In the end, the rushing car was operated by more than a dozen men and pounded the city gate.

However, Cheng Lian was not worried about the city gate at all, because the east gate of Tongguan had actually been sealed by loess and gravel. Even if the door was broken, it would be useless. The only ones that really threatened Tongguan were the twenty cars climbing the city tower.

These chariots had already arrived at the foot of Tongguan City and stood close to the city wall. Cheng Lian had ordered the crossbowmen to retreat to the second row, and the suspension bridges on the chariots fell one by one, and were on the edge of the city wall. The Cao army soldiers in the chariots rushed out and boarded the suspension bridge.

At the same time, the crossbowmen guarding the city loosened their bowstrings or buckled their swords together. Arrows shot towards the Cao army soldiers on the suspension bridge. With screams and wails, a large number of Cao army soldiers on the suspension bridge were injured and killed, causing considerable chaos. Some were squeezed down the suspension bridge and fell to death on the spot. Immediately afterwards, the spear soldiers in the defenders on the city head concentrated on the suspension bridge and stabbed the spears in their hands to the Cao army soldiers on the suspension bridge. The spears were too dense, and even if some Cao army sword players used shields to resist the spears in the middle of the opposite side, they could not defend against spears from the left and right ups and downs. Many people were stabbed through their heads or pierced through their limbs.

A soldier from Lu's army had just pulled his spear out of the other party's head, and three arrows shot into his body, two of which only penetrated his armor and did not penetrate his body. But a fatal arrow penetrated his face. The arrow did not come from behind Cao's army on the suspension bridge, but from above.

Not only these three arrows, but dozens of them suddenly shot at the Lu Bu army soldiers guarding the city. They were caught off guard, and a large number of soldiers were hit by the door or other key points and fell to the ground and died. It turned out that the top floor of the tower car was higher than the left of the city, and they could also station troops. The crossbowmen on it emerged and shot the head of the city from a high point. The crossbowmen on the city quickly fought back and suppressed the opponent's long-range attack.

The Cao army soldiers on the suspension bridge took this opportunity to advance several meters to the top of the city, and were approaching the spearmen, and were about to break through the defense line listed by the spearmen at the top of the city. Cheng Lian gave the order, and the hundreds of shield soldiers behind came forward to fight with the Cao army soldiers. The two Cao army spears stabbed at the shield soldiers who rushed in front, and at the same time, a ring-headed knife slashed at him. He used a large shield to suppress the two spears, but the ring-handed knife slashed on his shoulders, slashing the shoulder armor and slashed it all the way to the shoulder blades. However, his own steel knife had stabbed into the other party's belly. In the severe pain, the knife had already taken off his hand, and a spear stabbed into his throat instantly.

Suddenly, sixty bare hands soldiers Lu Bu rushed forward with their pots and smashed them to the suspension bridge of the building truck. The Cao army soldiers dodged one by one. The pots hit the bridge deck or the ground at the city wall, shattered, and the fuel inside flowed all over the ground. Then, a torch was thrown, and a raging fire was soon ignited.

These building cars were obviously soaked in water, extremely humid and could not be ignited in a short period of time. However, the fire tightly sealed the exit of the building cars, so that Cao soldiers under the city could no longer continue to use the building cars to climb to the city. Almost at the same time, the soldiers of Lu Bu's army who were reserved in Guancheng had come to support, and the few Cao soldiers remaining on the city were quickly wiped out.

"Quick, push the carts back." Although Xu Zhu was a tiger general who was not good at intelligence, he knew that the fire would burn these hard-built carts to ashes. However, it was a little late for him to issue this order. The sixty soldiers threw several oil tanks into the inner chamber of the corridor behind the suspension bridge of the carts, and the fire became more and more fierce.

The Cao army crossbowmen who were still attacking down on the top of the building car were frightened when they saw this situation. They were afraid that the fire would block the retreat and the collapse of the building car would die, and they would flee one after another. After all the soldiers on the building car retreated, the Cao army soldiers pushed back more than 20 burning building cars with the rolling wood and rocks, and after paying a large price of casualties, they could not control the fire in the building car. They could only watch the building car be dried and ignited by oil fires, and finally burned into piles of ashes.

At this time, anger and anxiety were depressed on Xu Zhu's chest. It took him half a month to build these twenty siege tower cars, and it was ruined. In addition, the storm and siege machine did not have any effect. However, Xu Zhu couldn't think of any better way, so he could only temporarily stop the army and build siege equipment. At this time, he said in his heart: [It would be great if Guo Jia was by his side, maybe he could give him an idea.]

At this time, Guo Jia was on the Wancheng front in the south, assisting Xiahou Dun in the battle.
