Under Tongguan City, Cao's army rushed in and rushed over, fighting for a few hours, then retreating like a tide. Even the air force on the hot air balloon was useless, and Jia Kui was confused.

Looking at Cao Jun who quickly retreated beyond the range of the bomb dropper, Jia Kui felt that something was wrong the more he thought about it.

In the past few days, in order to deal with the upcoming Cao army, he built fortifications, strengthened city defenses, and built equipment, and never stopped for a moment. He even improved the crossbow to air, so he prepared Cao army to come and make ruthless. Unexpectedly, the other party did not follow the routine at all, which made people feel uneasy.

If something goes wrong, there will be a demon.

If Cao's army does not fly over from the sky, can we still drill down from the ground?

Crawling through underground?

Thinking of this, Jia Kui's face changed terriblely, and he shouted with all his strength: "Everyone obeys the order, step down the city wall, and step down the city wall, hurry up."

After saying that, they were the first to run away. The soldiers around them were confused and were confused. However, the soldiers' orders were obedient. They didn't think much about it and ran away.

Not long after leaving the city wall, a dull and loud rumbling sound came from the ground, and the sound came one after another like fart. Then thousands of Yuan Jun watched as the city wall they had worked hard to strengthen in the past few days slowly vibrated. As the vibration occurred, a spider-web-like crack appeared on the wall.

The vibration did not stop, but continued, and it became more and more violent, and the cracks on the wall also became more and more vibrated.

Yuan Jun under the city was frightened by this scene, standing there as if he was immobilized, and he was stunned. Jia Kui's pupils shrank into pinholes. He stared at the shaking city wall for about three minutes. The city wall finally couldn't support a piece of collapse, revealing a gap about meter wide.

The violent sound of the collapse was like a heavy hammer hit Jia Kui's heart and woke him up on the spot. Jia Kui was so excited that he shouted: "Come Guanzhong materials together and set fire to the fire. Damn Cao's army, this battle cannot be fought."

Yuan Jun was awakened by his loud voice and became busy quickly.

In the camp of Cao's army outside the city, Cao Cao and his generals were also staring at the city wall. When they saw a piece of collapse, they shouted excitedly: "Dian Wei Xuchu, hurry up and guard the gap, and you must guard it for me."

When he said that, he found that the voice had changed, just like the eunuch's duck voice, and even he was shocked.

Tongguan is the last barrier to guard Chang'an. If you break through here and enter Chang'an, there will be no obstacles. If you take Chang'an, half of the world will be his. How can you not be excited?

The second general Hum and Ha were also trembling with excitement when he heard this, pulled out his weapons and rushed forward with a scream.

After entering Bingzhou, Cao's army crushed all the way. They had no chance to fight at all. They could only stay with Cao Cao as bodyguards. Seeing others contributing to others but not being able to kill the enemy, this was simply torture for the two militants.

The two of them didn't even ride a horse, and soon rushed out of six miles, trampling into Guanzhong on the collapsed gravel and rotten tiles.

Looking at the two powerful generals with pig bodies but bursting out of rabbit speed, Cao Ang smacked his lips enviously, "The physical fitness is so good, I want to be such a tough guy."

Cao Cao looked at his body that was slimmer than the 28th girl, shook his head and smiled bitterly, "You are a waste in this life."

Under the leadership of the two generals of Henha, Cao's army rushed into Tongguan like a wolf. Before the battle could be fought, a large fire ignited in Guanzhong. The flames rose higher than the city wall, and the rolling smoke rushed into the sky. Cao Cao's face changed slightly and he hurriedly said, "Go and see, what's going on?"

The barrier is about to break, so don’t change at this time.

The messenger left quickly and returned soon, shouting: "Report to the lord, Jia Kui burned all the supplies in Guanzhong and ran towards Chang'an with the soldiers guarding the pass. Dian Wei and Xu Chu are working hard to put out the fire."

It is difficult to walk from Gao Nu to Tongguan, and it is not easy to transport supplies. If the materials in the pass can be saved, they can save a lot of trouble.

Cao Cao ordered: "Gan Ning, you are a navy, born to defeat fire, go and rescue quickly."

Gan Ning: "..." Lord, ancestor, be my Dragon Prince.

Gan Ning led his men into the pass quickly and worked with the two generals of Henha to put out the fire. After nearly two hours of busyness, he saved one-third of the supplies.

Despite this, Cao Cao was quite satisfied. He patted the shoulders of several people and praised them, leaving two regiments of troops to station in Tongguan. The army continued to set off to rush to Chang'an. At the same time, he sent Zhang Liao to lead the cavalry to chase Jia Kui who escaped one step ahead of them. As for whether he could catch up, it depends on his fate.

It was less than 300 miles from Tongguan to Chang'an, and the journey became flat. It was rare to see the undulating hills. Zhang Liao rode his fast horse and chased after him. He soon caught up with Jia Kui's tail.

The Yuan army defended Tongguan had about 8,000 people, and only 2,000 cavalry. In order to keep pace with the infantry, they did not fully speed up, and they were caught up by Cao's army.

Yuan Jun had already been scared by the violent explosion in Tongguan, so he dared not fight. When he saw Cao's army chasing him, he threw away his weapons and surrendered on his knees.

The defeat was like a mountain of fallen. Seeing this, Jia Kui said nothing, so he decisively gave up his infantry and led his cavalry to escape to Chang'an.

Zhang Liao left a team of people to gather the surrendered troops and chased after him.

The two chased and fled, and soon arrived at the city of Chang'an. Jia Kui stepped forward and called the door, but the defenders in the city did not dare to open the door easily. They said I would ask for instructions and let me pass it away.

Zhang Liao's pursuer was behind his butt. Jia Kui couldn't wait, so he had to ride his horse to the east gate, and thought to himself: "If it really doesn't work, go to Hangu Pass. If you have the ability, you can continue chasing."

He arrived at the East City soon, and the generals guarding the city did not dare to open the door. Jia Kui had no choice but to continue to go east and seek help from Hangu Pass.

Less than twenty miles away, a cavalry rushed towards him, about 20,000 people. Under the banner of Zhang, Jia Kui raised his telescope and saw that Zhang He was the leader. He immediately became very happy and quickly greeted him.

He was excited, but Zhang Liao, who was chasing behind, became furious. He saw Zhang He's familiar face in the telescope and ordered: "Change, turn around, and change the front team and run.

"He only has more than 8,000 people around him, and he ran for several hours in a row. He was so tired that he dared not fight with Zhang He. Thirty-six strategies are the best way to leave.

He wanted to leave, but Zhang He was unhappy and led his troops to chase him quickly.

In an instant, the hunter turned into prey, and the prey turned into a hunter again. The character changed so quickly that it was so dazzling.

When passing by Chang'an City, the defenders on the city watched Cao Jun who had roared past and escaped faster than before, with a very wonderful expression.

At the north city gate, Ju Su and Xu You, who had received the news, rushed over quickly, looked at the departure Cao army with a telescope, and were also a little confused. They did not react until Zhang He led his army to pass by the city and yelled hurriedly: "Open the city gate quickly and go out to help. We must kill this Cao army under the city."

At this time, the door was opened and the daylily was cold. The defenders in the city went out and followed Zhang He's army to eat ash for several hours, and finally returned with Zhang He and Jia Kui.

Ju Su and Xu You went out of the city to greet each other in person. After meeting and saluting, Ju Su asked excitedly: "Junyi, why did you suddenly appear here?"

Zhang He smiled bitterly and said, "I lost to Cao's army that day and fled to Hedong County, and rushed to Hangu Pass to help Qianzhao General repel Cao Ren. Considering that the Chang'an defenders were insufficient, I rushed over."

Ju Su patted his shoulder and smiled, "It's great. With you joining, I will be more confident in defending Chang'an City. We don't need to hold on for long. Just hold on for half a month. When the news of Uncle Liu becoming emperor came, Cao's army would naturally retreat."

"Uncle Liu proclaimed himself emperor?"

Zhang He was shocked and asked quickly: "What's the situation?"
