Zhang He looked solemnly at the Shu army at the gate of the camp who was cleaning up the broken wood of the camp, and the return cannon advancing step by step in the distance.

Seeing this, the soldiers under Zhang He's command saw that the return cannon continued to advance, and their faces changed in fright, and they retreated one after another, Zhang He shouted when he saw this: "Brothers, don't be afraid, let alone retreat, there are not many trebuchets in the Shu army, only twenty, and they can only throw twenty stone bullets at one time, and they can hide when they see the landing point."

Once you retreat, you will mess up the formation, Shu generals Zhao Yun and Zhang Fei will definitely take advantage of the situation to lead their troops to rush over, and more people will die at that time! We must delay time and let Zidan lead his troops to break through! ”

Although this is the case, Zhang He's words still can't stop the soldiers' fears.

And the boulders that fall quickly are not so easy to dodge.

As the return cannon advanced step by step, the Cao soldiers also retreated step by step.

"Don't mess up, don't mess up, just look at the boulder landing point and hide to the side!"

Zhang He tried hard to maintain the formation, but to no avail.

With Wei Yan's order in the distance, twenty boulders were thrown out again, flying straight towards Cao's army.

"Ahh

"Don't!"

The boulder fell like a meteorite in the Cao army, and a miserable scream sounded, although there were not many stones, and they could kill dozens of enemies at one time, but it made Cao Jun's formation chaotic.

"Hurry up and re-align, don't mess around!" Zhang He once again maintained the formation, so as not to take the opportunity for Zhao Yun and them to come in.

On the other side, Cao Zhen also gathered the remaining soldiers and horses and led them to kill from the direction of the east gate.

Zhuge Liang had already discovered that Cao's army wanted to abandon the camp and flee, so he sent a large number of soldiers and horses to the east gate to intercept them, and the soldiers and horses of the two sides fought fiercely at the east gate.

It's just that the strength of the Cao army to break through reached 60,000, and the Shu army's soldiers and horses at the east gate were only tens of thousands, and the Cao army broke through, but it was not so easy to stop.

Cao Zhen took the lead, stabbing left and right, rushing back and forth in Shuzhong, and soon killed a bloody road, leading the soldiers and horses to flee eastward.

In the camp, Zhang He led the Cao army to be bombarded by the return artillery for several rounds, and hundreds of soldiers died under the boulders.

Although Zhang He constantly maintained his position, every time a boulder flew in, the soldiers unconsciously dodged in all directions.

At the gate of the camp, Zhao Yun and the other generals saw that Cao Bing's formation was in chaos, although Zhang He maintained the formation, it was to no avail, so he said: "When the boulder falls this time, let's rush over!" ”

Zhang Fei rubbed his shoulders and said, "I've been waiting impatiently for a long time!" Why bother shelling them with return artillery and waiting for their formation to be out of order? Shall we just kill it? That's where it's fun! ”

Zhao Yun, Lin Xiao and others shook their heads and smiled bitterly, the lives of soldiers are precious, although they can win by directly rushing to kill, they are bound to lose both, first bombardment with back artillery, and then rush to kill, they can save the lives of many soldiers, so they naturally have to do this.

After another round of boulders fell, Zhao Yun and the others immediately led their troops to kill without waiting for Zhang He to organize a formation, and Wei Yan in the rear saw this and immediately asked the soldiers to stop firing back the cannon.

Zhao Yun, Lin Xiao, Zhang Fei, and Huang Zhong rushed into the camp and went straight to the front to kill Cao Jun.

Seeing that the front was full of world-famous, brave and invincible Shu generals, the Cao army did not dare to engage in the battle at all, and there were a large number of Shu troops in the direction of the east gate, and the Cao army fled towards the north gate.

Zhang He also did not dare to engage the Shu army, but instead rushed to the front of the team and retreated.

The Cao army fled, the Shu army chased and killed, and the shouts of killing all over the mountains resounded throughout the Northern Plains.

Under the offensive of the Hui artillery, Cao's army retreated without a fight, abandoned the camp and fled.

………………

…………

Three days later, the messenger arrived in Chang'an as quickly as possible.

Chang'an, the palace of King Wei.

Cao Cao's roar sounded in the hall: "What do you say, he ...... Miaocai"

The soldier said sadly: "Shu General Huang Zhong challenged, General Xiahou did not listen to the advice to go to war, ambushed in the Wei River, was beheaded by Huang Zhong, and after returning to the camp, he died!" ”

"Wonderful!" Cao Cao suddenly fell on the desk and cried bitterly.

The envoy said: "And the Shu army also built a powerful trebuchet, the stone weighs three or four hundred catties, can shoot two or three hundred steps, just a round of bombing, our army camp was breached, and now General Zhang He and General Cao Zhen retreated to Wugong County......

Wugong County is small, but I am afraid that I can't stop the Shu army, Jiang Jijun and General Zhang He sent a message, so that King Wei could prepare early! ”

Cao Cao was still crying bitterly: "Miaocai, Miaocai, how can you bear to abandon me.!" ”

Seeing Cao Cao's grief, Cheng Yu asked the envoy, "How many soldiers and horses are left now?" ”

The messenger replied: "After two battles, we lost nearly 20,000, and now there are only 50,000!" ”

"King Wei!" Cheng Yu's face changed in fright, and he hurriedly said to Cao Cao: "Now that the Beiyuan camp has been broken, the Shu army will definitely occupy the street pavilion, and the Liangzhou reinforcements are afraid that they will not be able to enter in a short time."

The trebuchet is so powerful, the cities along the way are afraid that they will not be able to resist for long, and they also ask King Wei to temporarily give up Yongliang and quickly retreat to Tongguan! ”

"Smack!" Cao Cao slapped the table and shouted angrily: "Retreat to Tongguan, don't you want Yongliang?" ”

Cheng Yu said worriedly: "But...... Now the Liangzhou reinforcements can't come in a short time, and the state, the Si Li reinforcements are still on the way, if Liu Bei leads the troops to Chang'an, how to defend himself at that time? ”

"Beiyuan is still hundreds of miles away from here, Liu Bei's army is tens of thousands, and he carries heavy trebuchets, even if the city is broken in a battle, it will take at least a month to get by, what are you panicking about?" Cao Cao quickly came out of his grief, stabilized his mind, and immediately looked at the messenger and asked, "Do you remember the outline of the trebuchet?" ”

The messenger replied, "Remember one or two! ”

"Good!" Cao Cao ordered: "You immediately draw the outline of the trebuchet for me." ”

"No!" The envoy gave up his hand, and the attendant brought pen, ink, paper, and inkstone, but after a while, the messenger drew the general outline of the return cannon according to his memory.

"Ziyang!" Cao Cao looked at a man in the row of civil officials and said, "Look at this drawing, can you figure out the structure of the trebuchet of the Shu army!" ”

Liu Ye took the drawings from the messenger's hand and looked at them, and said after a long time: "The general structure is understood, but to build it, it still needs to go through many tests, and it will take at least twenty days!" ”

The structure of the return cannon is actually not complicated, Liu Ye is good at carpentry, and with the drawings of the general outline, he basically figured out the structure of the return gun, but if he wants to create a truly powerful return gun, it will take a while to explore.

Cao Cao nodded and said, "There are still 5,000 defenders in the city, I will give them to you, within a month, be sure to build me fifty trebuchets!"

In addition, Zhang He, Cao Zhen, and Jiang Ji were ordered to defend the city for me, block Liu Bei from city to city, and be sure to delay the Shu army for two months! ”

"No!" Liu Ye and a general in charge of delivering the message surrendered their orders.

Cao Cao ordered again: "Immediately send people to Liangzhou quickly, order Guo Huai to stay in Qishan Fort with 10,000 soldiers and horses, lead the remaining 20,000 soldiers and horses to join the Western Regions coalition army, quickly break through the street pavilion, kill to Guanzhong, attack the Wuzhang Yuan Shu army camp, and cut off Liu Bei's way back!" Cut off its food and grass! ”

"No!"

Cao Cao faced Cao Hong again, and Sun Li and the others ordered: "Cao Hong, Sun Li, you two immediately gather the young people in the city, build a deep ditch and high fortress outside the city, and build a dirt mountain to prevent the Shu army from attacking Chang'an with trebuchets when the time comes!" ”
