The problem in front of Hu Zhen is not to rescue Thorn Yang, but how to maintain the reconstruction of Wancheng.

There are more soldiers and horses, and it is not certain whether they can recapture Jianyang, but it will delay the project on this side of Wancheng.

In terms of taking 10,000 steps back, even if he recaptures Jianyang, it has no strategic significance, Zhang Fei's soldiers and horses are all cavalry, coming and going like the wind, where can't he settle down?

There is no food, just go to any town to fight the autumn breeze, and now Nanyang also grows corn and sweet potatoes, and the people are also very rich, and there is no shortage of food at all.

Zhang Fei was about to lead the cavalry over, and his purpose was naturally needless to say, it must be to destroy the reconstruction of Wancheng. Therefore, how to maintain the reconstruction project of Wancheng has become the biggest problem for Hu Zhen at present.

The generals were silent, thinking about a solution to the problem.

Suddenly, the general Niu Jin proposed: "Why don't you camp outside the four gates overnight, send soldiers and horses to station, and prepare enough shields, bows and arrows to prevent the Shu army from approaching?" ”

This Niu Jin is in Nanyang, he is an old general, at the beginning he was Cao Ren's general, when Cao Cao went south, he was defeated by Chibi, leaving Cao Ren to guard Nanjun, Zhou Yu led his troops to attack Cao Ren, and this Niu Jin once followed Cao Ren against Zhou Yu.

Up to now, Niu Jin has been in Nanyang for more than 20 years, and the governor of Nanyang has changed batch after batch, but Niu Jin is still very strong.

Speaking of this Niu Jin, there is another story related to him in history, this story is called Niu Jimahou.

During the Cao Rui period, there was a widely circulated book called "Xuanshi Tu", which recorded the prophecy of "the ox follows the horse".

Sima Yi later became powerful in the world, thinking of the prophecy of "Niu Jima", his surname is Sima, this Niu Jima, doesn't it mean that the surname Niu will replace his Sima family? Therefore, Sima Yi was very taboo in his heart, fearing that Niu Jin would be unfavorable to his descendants in the future, so he poisoned him.

Sima Yi thought from then on that Niu Jin was dead, and his descendants would be able to sit back and enjoy wealth and prosperity, but he didn't know that the world was unpredictable.

Sima Yi's grandson Sima Zhen attacked Queen Langya, and his wife Xiahou was made a concubine. But the Xiahou clan was profligate, and it didn't take long for him to have an affair with a small official in the palace with the same surname Niu, and then gave birth to Sima Rui.

This Sima Rui was later the founding emperor of the Eastern Jin Dynasty, and the prophecy of Niu Jima really came true.

As soon as Niu Jin's suggestion was spoken, the general immediately objected: "The Shu army has 10,000 cavalry, and we only have 30,000 soldiers and horses now, and there are only more than 7,000 people in the four gates, can we prevent the cavalry of the Shu army?" Even if it can be defended, the soldiers are all sent out, who will build the city? ”

Niu Jin said in a deep voice: "Then what should I do?" Is there any other way to defend against the Shu army? ”

When the generals heard this, they fell silent again, and they racked their brains, but they couldn't think of a way to prevent the destruction of the Han army.

Hu Zhen muttered: "The Shu army is all cavalry, coming and going like the wind, if you want to defend it, you can't prevent it." If you want to build any fortifications, the Shu army will arrive tomorrow, and it will be too late, and now the plan can only be retreated. ”

"Settle for the next best?" The general asked suspiciously.

Hu Zhen nodded, and picked up a piece of rice paper on the table, the content of this rice paper was the materials for building the city.

Looking at the rice paper, Hu Zhen said: "Originally, I expected to build a city five zhang high, but now it has a height of one zhang and eight feet. The Shu army will arrive tomorrow, and if you want to reach the predetermined height, I am afraid that it will be impossible. ”

To build a concrete city wall, both sides should be fixed with formwork, leaving a groove in the middle, tie bamboo bars in it, and then pour concrete into it. As the walls get taller and higher, frames are erected with bamboo on both sides of the walls to make it easier for construction workers to go up and pour concrete.

The Han cavalry will kill Wancheng tomorrow, and then they only need to build a few trebuchets and bombard them with stones to destroy the frame on the outside of the city wall, as well as the template model used for construction. How to increase the height?

Hu Zhen continued: "The most important thing is cement, the place where we burn cement is outside the city, as long as the Han army sends troops to fight, we can't build this city wall without cement." ”

"Yes, that's the hardest thing to do, and those places aren't dangerous places, and they can't be defended at all."

"What if you keep it? The Shu army is all cavalry, they intercept it on the road, and the cement can't be transported into the city. ”

Hu Zhen clapped his palms, signaled the soldiers to be quiet, and then continued: "I have calculated, the cement hoarded in our city, as well as the burned cement outside the city, plus stones, sand and other materials, are enough to increase the height of the city wall to three zhang.

What I mean is to send people to the city overnight to bring all the materials and cement to the city, and let the craftsmen increase the frame of the city wall to three zhang, when the Shu army arrives, we will send troops to deal with the Shu army, delay the time, and the rest of the men and horses will keep pouring down the city wall day and night.

The height of three zhang, although it does not reach the height we expected, once it is completed, it is enough to block the Shu army. As long as there is enough food and grass in the city, you can keep it for as long as you want. ”

The generals listened to Hu Zhen's analysis and nodded one after another: "Today's plan can only be like this." ”

Seeing that the generals agreed, Hu Zhen ordered: "Niu Jin, you quickly organize people to move all the cement and construction materials outside the city to the city." Zhao Fei, you immediately organize craftsmen and ask them to raise the frame of the city wall to three zhang. ”

"No!" The generals took orders.

On the other side, in Jianyang, early the next morning, Zhang Fei led his troops to leave Jianyang and went north to Wancheng.

When it was close to noon, Zhang Fei led his troops to Wancheng.

At this moment, the mountains of sand and gravel piled up around the outside of Wancheng have all been moved to the city.

Originally, the height of the cement city wall of Wancheng was only one zhang and eight feet, that is, four meters three, but now it has three feet and a height of seven meters two.

However, the lower part of the city wall is a concrete city wall with a height of one zhang and eight feet, and the upper part is only fixed with a formwork, which is still a model, and the middle is hollow and has not yet been filled with concrete.

Inside and outside the city wall, there are also bamboo frames and springboards, which are convenient for builders to pour cement and fix formwork.

Zhang Fei led his troops to Wancheng, and when he saw the city wall that was already three zhang high, he couldn't help frowning: "Why is this Wei army so fast?" This wall looks like it's already three feet high, right? At such a height, if you want to attack Wancheng, it will be difficult! ”

"Father, look at the wall!" Zhang Bao looked at the city wall carefully for a while and said, "The bottom part of the city wall is made of concrete, but the top is made of wooden planks. Looking at the surrounding ground, there is still a lot of sand and gravel.

According to my estimate, a large amount of sand and gravel should have been piled up outside the city, but now there are so many traces left on the ground, it should be that the Wei army went to the city overnight, and if it was used up, it would not be so chaotic.

If I expected it to be true, the top half of the wall should have been hollow, and no concrete had been poured into it. It should be that Hu Zhen knew that we arrived last night and was worried that we would destroy it, so he made arrangements overnight. ”

"Hollow?" Zhang Fei's eyes narrowed when he heard this, and the upper part of the city wall was pasted with a layer of wooden planks, which could not be distinguished by the naked eye alone.

"Give me the gun!" After looking at it for a while, Zhang Fei took a spear from the soldier's hand, suddenly clamped the horse's belly, suddenly increased his speed, galloped his horse, and threw the spear towards the upper part of the city wall.

There was only a click, and the spear was nailed to the plank, and the barrel of the gun was more than half inside.

Zhang Fei looked at the spear that entered most of the wall and said: "Sure enough, it is hollow, the concrete is extremely strong, if it is concrete inside, this spear will not be able to penetrate it at all." Only if it is hollow can it be pierced so deeply. ”

Zhang Bao nodded and said: "That Hu Zhen knew that we were coming, so he moved the materials to the city overnight, because the height of the city wall was not enough, so the formwork was fixed in advance, and it should be ready for construction in the city." ”

Zhang Fei said disdainfully: "Construction in the city? The formwork needs to be fixed inside and outside the wall, so I just have to ask the soldier to build a few catapults, blast the formwork and see how he works in the city. ”

Zhang Bao groaned: "Hu Zhen will choose like this, I'm afraid it won't let us get our wish." ”

Zhang Fei nodded and said, "Immediately assign a part of the manpower and let them cut down the trees, and let's set up camp first." ”

Zhang Fei's mission this trip was to destroy the reconstruction project of Wancheng, so Liu Chan also sent him a few special talents, but Zhang Fei did not choose to build a return cannon, but to build an ordinary trebuchet.

The construction of the return cannon is more complicated than that of ordinary trebuchets, and it uses hundreds of catties of large stones, and when it is ready, it may be three or five days later, and three or five days is enough for the Wei army to finish pouring the red concrete.

Hu Zhen and the others will stand on the head of the former Wancheng City, and the city wall of the new Wancheng City is built around the old Wancheng, just twenty meters away.

Therefore, the old Wancheng and the new Wancheng only saw, and formed a hollow corridor, at this moment the gate of the new Wancheng has been closed, and the construction materials that were moved to the city last night were hoarded in this hollow corridor.

The soldiers and men of the city were also among them, mixing the concrete and hurrying to fill the hollow wall.

Hu Zhen looked at a group of Han soldiers who went to the nearby mountains and forests and said: "The Shu army sent people to the mountains, I am afraid that they will cut down trees to make catapults, and they are ready to make a move on the city." ”

Niu Jin clenched his fists and said, "We must not let them succeed!" ”

Hu Zhen nodded, and muttered: "The cavalry led by the Shu army is cavalry, not heavy cavalry, this kind of cavalry is good at guerrilla warfare, and it is difficult to charge and kill head-on.

If the Shu army comes to destroy, you can send soldiers out of the city, set up a circle formation, arrange shield soldiers outside, and arrange archers inside, so that the Shu army will not dare to approach the city wall, General Niu Jin, when the Shu army comes to attack, you will fight the Shu army. ”

"No!" Niu Jin gave his hand to the command.

Now that the weather is getting hotter, Zhang Fei also has to stay in Wancheng for a while, so it is not possible to build a camp.

The soldiers were quickly cut down the trees, which were used to make catapults on the one hand and for encampment. As for supplies such as tents, Zhang Fei didn't bring them with him on this trip, but he got a batch in Jianyang, which just came in handy.

It was busy until late in the evening that the camp was established.

In the open space of the camp, a group of craftsmen were busy building trebuchets, and Zhang Fei said to them: "I have worked hard for you tonight, and I will build the trebuchet overnight, and I will use it tomorrow." ”

Zhang Bao said to Zhang Fei: "Father, you see that the lights are bright in Wancheng, and the soldiers are afraid that they are rushing to work overnight." ”

Zhang Fei nodded and said with a smile: "Well, there is no need to be afraid, this concrete is poured well, and it will take time to dry, and when the trebuchet is built tomorrow, it will be bombarded with a trebuchet, and the city wall they watered tonight will become tofu slag." ”

In the past two years, Chang'an has been built, the original old Chang'an City has become an imperial city, the people have moved to live outside the old city of Chang'an, the construction of various facilities, all cement is used, Zhang Feijiu is in Chang'an, under the influence of the ears and eyes, and the concrete operation is also very understanding.

Seeing that the Shu army did not move at night, Hu Zhen breathed a sigh of relief and asked the soldiers to speed up, and in one night, the height of the city wall increased by three feet.

Three feet doesn't sound like much, but you must know that this is a city wall, very wide, and very long, and the four walls are raised together, and it is already a very good thing to be able to increase the height of three feet in one night.

However, Hu Zhen was not happy for long, and the next morning, Zhang Fei led the soldiers out of the camp.

Trebuchets, craftsmen rushed to work last night, and more than thirty have been built.

Yesterday afternoon, the soldiers also got a large number of stones, because the establishment of Wancheng also needed stones, so the Wei army opened a stone mine nearby, this stone mine was found by the Han army, and there were a large number of board cars, baskets, just cheap for the Han army, used to carry stones.

Zhang Fei led 9,000 cavalry in front and 1,000 soldiers in the rear, pushing trebuchets and carrying stones to follow.

The shooting distance of an ordinary trebuchet is not far, only less than a hundred steps, because the city wall of the old Wancheng is twenty steps away from the new city wall, these twenty steps plus a hundred steps is one hundred and twenty steps, and this distance has exceeded the effective range of the bow and arrow.

Therefore, the Wei army could not shoot the Han army with bows and arrows on the walls of Laowancheng.

Zhang Fei led the soldiers and horses out of the camp and advanced step by step, they came from the south, and the camp was also outside the south gate, so it was the south gate that attacked.

Seeing this, Hu Zhen at the head of the city immediately ordered: "Niu Jin, quickly lead the army to kill, intercept the Shu army, and don't let them come." ”

"Brothers, kill with me!"

Hu Zhen gave Niu Jin 10,000 soldiers to block the Han army, 7,000 shield bearers, and 3,000 archers.

Niu Jin led the shieldmen out of the city first, and set up a circle outside the city, and then the archers quickly entered the formation.

Zhang Fei led the cavalry to arrive and stopped when he was a hundred paces away from the circle.

Zhang Fei looked at the circle in front of him and said, "What a beard, there are really two hits." ”

When the first general heard this, he surrendered his hand to the battle: "General, what a round formation, give the last general a thousand cavalry, and keep his formation." ”

Although Zhang Fei is reckless, he is thick and fine, and he is proficient in the art of war: "My ten thousand soldiers and horses are all light horses, using bows and arrows, and the range of horse bows is not as good as that of foot bows. When the archers in the array shoot arrows, how many of us have to die? ”
