The city of Chencang is not very tall, but it is built on the mountain, and the terrain of the mountains and rivers is integrated into the defense system of the city.

"Where are the reinforcements sent by Cao Ei?"

In the camp tent, Yang Yun, Zhuge Liang and others were holding a military meeting, and before the military meeting, Yang Yun first asked Cao Rong about his reaction.

At this time, several days have passed since Zhang He's entire army was annihilated, and even if the spies of Wei were incompetent, Cao Rong should have received this news.

Chencang is located at a critical point. At the beginning, Han Xinming repaired the plank road to darken Chen Cang, and after crossing Chen Cang, the land of Sanqin was in full view, without this city as a barrier, Zhang Han, a famous general at the end of Qin who could fight against Xiang Yu, was defeated in front of Han Xin and gave up eight hundred miles of Qinchuan.

Now, Yang Yun has embarked on the strategy of Liu Bang going out of Hanzhong, setting Qinchuan, and then competing with Xiang Yu for the world.

As long as the Wei army can be defeated and Chang'an can be taken, the national fortunes of Shu will leap forward, restore the situation when Qin unified the six countries, and use Guanzhong, Bashu and Nanjun to fight against Cao Wei's Kanto.

"Your Majesty, Cao Rong takes Cao Zhen as the general, leads 150,000 troops, and is marching west day and night, presumably in seven days, he will be able to rush to Chencang City!"

Zhuge Liang was in charge of the logistics of the army. The more powerful he was in intelligence, marching, and warfare, the more cautious he became. We attach great importance to intelligence.

Any news that a scout horse finds out, he has to see it himself. So after Yang Yun asked, he replied without thinking.

"In seven days, we will be able to reach Chencang? Then, with Kong Ming's intentions, should our army immediately attack the city and take Chencang before Cao Zhen arrives, so as not to be attacked from both sides, or let it go?"

Hao Zhao in Chencang City is also a famous general, Yang Yun naturally does not dare to take it lightly, in case he is attacked by the Wei army on both sides, the Shu army will be at a strategic disadvantage.

"No, if our army takes Chencang, Cao Zhen's army may not continue to come!

For the Wei State, Chen Cang could not be easily abandoned, so before Chen Cang was breached, the Wei army would definitely come to support, this was a matter of course, and there was nothing to hesitate about.

However, if Chen Cang is breached, then there is no reason for the army to continue to advance westward to support.

Encirclement and reinforcements...... When Yang Yun heard this, he suddenly thought of the Battle of the Tiger Prison when the Tang Dynasty attacked Luoyang in history.

The first world he experienced was to help Li Shimin kill Wang Renze. Participated in the Battle of the Tiger Prison. Therefore, Yang Yun was very impressed by this battle.

And now they are surrounding Chen Cang, waiting for Cao Zhen to lead troops to come to help. It seems to be a copy of the Battle of the Tiger Prison. However, in the battle of the Tiger Prison in history, Li Shimin destroyed the two kings in one battle and laid the foundation of the Central Plains and Hebei. The situation that allowed Datang to dominate the world can no longer be reversed.

And now in the battle of Chencang, if he wins, he will only win Guanzhong.

"I don't know, Cao Zhen or Dou Jiande in history, who is more capable?"

Yang Yun's thoughts swirled in his heart.

Although Zhuge Liang's strategy was to leave Chen Cang and wait for Cao Zhen's reinforcements, it was impossible for the army to do nothing when it arrived at Chen Cang City.

Yang Yun sent Guan Xing and Zhang Bao to each lead troops and horses to attack Chencang. Conduct a tentative siege.

Rumble!

The catapult roared, and the stone projectiles flew towards the city wall, making a heavy roar, and the rubble splattered in all directions, killing and wounding many soldiers in an instant.

However, Chen Cang's guard Hao Zhao reacted very quickly, and quickly sent someone to cover it with thick cotton felt to relieve the force of the falling stones, so that the damage of the splashed gravel was instantly reduced.

The catapult did not play its due role, and soon the Shu army launched the well rail car. Hao Zhao wrapped a long arrow in fire oil and shot a rocket at the well fence car, which soon burned the well fence.

......

Guan Xing and Zhang Bao kept trying to attack with soldiers and horses, but they were blocked by Hao Zhao every time. The city was besieged for three days in a row, but the city walls were not even climbed.

Seeing such a scene, even Zhuge Liang had a love for Hao Zhao, who was guarding the city.

"Hao Zhao was able to use 3,000 troops to make Guan Xing and Zhang Bao helpless, which shows his talent. There are so many talents in the Wei State...... If Hao Zhao can be subdued, then our army will be able to have one more general!"

Zhuge Liang sighed constantly, and also sent envoys into the city, wanting to persuade Hao Zhao to surrender.

If Hao Zhao can surrender, the Shu army will be able to face the approaching Cao Zhen army more easily. Reduce the disadvantage and increase the odds of winning from 70% to 90%.

Yang Yun naturally knew the result of persuading Hao Zhao to surrender, but Hao Zhao's ability was indeed outstanding, so he didn't stop it.

However, it is clear that Zhuge Liang's persuasion was in vain.

In less than half an hour, the messenger who had been put into the city by the hanging basket was returned. Hao Zhao firmly rejected Zhuge Liang's solicitation.

"It's too difficult to persuade a general like this kind of general who has served Cao Wei in the army since he was a child!"

Yang Yun sighed in his heart. He has followed Cao Wei since he was a child, and spent the most peak of his life in Wei State, and has made many contributions...... If he surrenders, it will undoubtedly be a negation of the previous achievements established in Cao Wei.

But not everyone can choose to surrender on their knees in order to save the lives of their soldiers like Yu Ban.

However, Hao Zhao's 3,000 troops guarding the city could not affect the overall situation.

Even if he resolutely refused to surrender, after the reinforcements led by Cao Zhen were broken, he would not be able to hold the city wall under the siege of tens of thousands of elite Shu troops.

With the support of the three counties of Longxi, the current Shu army is not short of grain and grass.

Hao Zhao's myth of repelling Zhuge Liang's tens of thousands of elites with 3,000 men and horses will not have a chance to be staged in this world again.

A few days later, an army of 150,000 led by Cao Zhen rolled in.

The cavalry and foot soldiers were black and oppressive, and as far as the eye could see, it was boundless.

"Like...... It's a bit of a big deal!"

After Yang Yun saw that there were two thousand Yellow Turban wrestlers in the army led by Cao Zhen, his face suddenly changed, and he felt that something was wrong. Two thousand Yellow Turban wrestlers formed a battle formation, which could block two peerless generals like Ma Chao.

His strength is a little worse than Ma Chao. Even if he continued to charge personally, it would be difficult to do anything to kill the enemy's commander.

"Kong Ming, do you want to follow the original plan now?" he turned his head to look at Zhuge Liang beside him.

Zhuge Liang frowned, then stretched out, his expression was calm, and he said with a smile: "Your Majesty, rest assured, the eight formations that the minister has personally practiced, as long as a large array is formed, Cao Zhen will not want to break through even if he has an army of 150,000!"

"For our army, as long as Cao Zhen's 150,000 army is dragged here, Zhao Yun and Wei Yan can take the opportunity to sneak attack Chang'an, even if the sneak attack on Chang'an is unsuccessful, it can make Cao Zhen unbearable!"

Once Chang'an was raided, the back road for the Wei army was unstable, Chang'an's hoarded grain and grass baggage could not be safely transported, and the 150,000 army seemed to be huge, but as long as it could not break through the eight formations of the Shu army, it would sooner or later be dragged down by the huge consumption of grain and grass.
