Lu Bu’s purpose is very clear. He uses resources to win over the mountain people in Danyang. These poor mountain people are afraid of being poor, so he will give them the food to whoever gives them.

The master's letter was arranged to brainwash them every day, so that some people could support Lu Bu, repair the roads and bridges, and go straight to Danyang City. The logistics road was unblocked. The 20,000 army plus tens of thousands of strong men could not support Danyang City.

As for Yuan Shu's support, it is impossible in the short term. With Cao Cao's cunning, he should be attacking Huainan now. Hefei has just experienced a great war and is unable to support Danyang.

Besides, Ji Ling led his troops to retreat. When he walked away, he found that his back was wet. Lu Bu's ambush circle was too pitiful. Thousands of car and crossbows were not a joke. I am afraid that with just one volley, his three thousand cavalry would collapse. The car and crossbows were too powerful and the deterrent power was too strong.

However, when Ji Ling talked to Lu Bu, the military supervisor was watching from behind. Although the military supervisor didn't know what Ji Ling and Lu Bu were talking about, he always felt that it was suspicious, so he decided to write a letter to Yuan Shu immediately after going back, and be careful that Ji Ling would sue Lu Bu.

After all, these two men had a friendship when they shot their halberds at the gate, so the military supervisor thought about it. No matter how they looked, Ji Ling was going to surrender to the enemy. But he didn't say anything and pretended not to know anything. Seeing that the field battle could not win Lu Bu, the group returned to Danyang City.

Because Lu Bu was willing to deposit his capital and food, he originally planned to recruit 10,000 strong men, but as he came, he exceeded the standard, and the team of 20,000 strong men.

There are so many people who work hard, and they repair the land almost twenty miles a day. In just seven or eight days, the spacious and flat official road has been built to the hinterland of Danyang County, only seven or eighty miles away from Danyang City.

Lu Bu set up a camp and discussed matters in the big tent.

Lu Bu asked Zhao Zhubo: "Is the location of Danyang Fortress good?"

"I chose it, five miles south, and there are tens of thousands of acres of wilderness and flat land nearby to facilitate farming. Danyang Fort is 18 zhang higher than the flat land, which can effectively prevent rainwater. The fortress is planned to be square, with two miles of city walls on the east, west, south and north sides, and a circumference of eight miles. It covers an area of ​​1,500 acres and can accommodate 5,000 elite troops to garrison. Vegetable fields, vegetable gardens and breeding farms can be cultivated in the fortress, etc.."

Zhuzhu Zhao took out the drawings for Lu Bu to show, and Lu Bu was still very satisfied after reading them.

Xuzhou inherited Tao Qian's accumulation and had many capable people. There was a senior craftsman named Tao Zong in civil engineering planning, who was proficient in the construction and supervision of cities.

However, the generals looked a little mysterious, and Zang Ba smiled and said, "My lord, we are fighting, so how can we have time to build a city? Although this is at most a pass, it is eight miles in circumference and even if the city wall is four meters high, it is a huge project, and it is not that easy."

"What Xuan Gao said is, but this position is too important. When we take down Danyang City, Danyang Fort will become his gateway and can effectively prevent the attack of the Jiangdong Army. Sun Ce is not a fuel-efficient lamp, so we must guard against him. As for time, let's ask Master Tao."

Lu Bu asked someone to call the pottery craftsman, he is an expert.

Lu Bu asked: "According to our design, if 30,000 strong men come to build this fortress, with stones on the foundation and bricks on the city wall, how long will it take to build it?"

"There are bluestones on nearby mountains that can be mined, and it is most appropriate to lay the foundation. The foundation can be completed in a month. There are bricks on both sides of the city wall and rammed earth in the middle. The blue bricks are burned too slowly for about a year and a half to complete."

"One and a half years have been too long. If you don't have to consider the time to burn bricks, how long will it take if we have ready-made bricks and use cement to build walls?"

Master Tao calculated: "After half a year, it will take half a year to lay the foundation and the city wall. It's enough. Don't be too high in the city wall, three or four zhang."

At this time, the height of 1 zhang is two meters and two meters, and the height of 3 zhang is more than six meters. With the female wall, it is still no problem.

"Three feet high is enough. The purpose of our construction of this castle is to tell the people of Danyang that we really plan to stay and start the management of nearby town and villages while building the castle."

He did it right away and transferred 10,000 people to the mountain to mine bluestone, iron chisels, hammers, and stones that were smashed were rising. It seemed that there would be enough stones in ten or eight days.

The foundation is made of stone, but for the speed of construction, bricks are needed. However, there is no coal here, and there is no ready-made brick factory. When everyone is not sure about this, Lu Bu took action.

One thousand five hundred soldiers from Xu Sheng's army were transferred to mix sand and cement to make cement bricks. Because it was a castle, the proportion of cement was relatively high.

A large piece of cement brick was more than 20 kilograms. At the beginning, I was not skilled and had few molds. In a few days, I became proficient in the production of more than 70,000 yuan a day. Moreover, this thing was hard as a stone in more than ten hours. The generals were stunned. Unexpectedly, it turned out to be such a magical thing.

Zang Ba exclaimed: "With this thing, you can be a city overnight."

"It's just where I've been, all handmade, very slow. But the quality is unreasonable. Our cement bricks are sturdy and can be used for a hundred years."

Zang Ba took a hammer, found a cement brick, and then slammed it. It took a lot of effort to smash it.

"Awesome, as hard as a stone."

There is no need to say that these strong men in Danyang do their hard work, and they can make do with the road construction. However, the advanced technology of building cities requires craftsmen. They really can't do it. Tao Zong's method is to use Danyang as small workers, leading the two thousand craftsmen brought from Xuzhou, and Sun Guan led his troops to monitor and inspect them every day.

The main reason is that there are spies from Yuan Shujun who have been infiltrated, the craftsmen and spies in the team are highly vigilant, and no abnormalities have been found yet.

There is no need to be too wide for this kind of small castle wall. Two meters is enough. After the foundation is laid, the wall is laid, and the wall is rammed with earth. In order to ensure the solidity of the wall, steel bars are used between the two walls to pull it into the middle, and a beam is added at a distance.

After another month, it is already late spring and early summer.

Ji Lingbai scratched his heart and watched Danyang Fort rise. It would be difficult for this big fortress to break through again.

Yuan Shu became dissatisfied with Ji Ling. Huainan and Cao Cao had a few small battles. Guo Jia made a plan to cheat Lu Bu, which was to withdraw his troops.

Once Cao's army withdrew, Yuan Shu could concentrate on dealing with Lu Bu. Yuan Shu's army of more than 100,000 could not defeat Lu Bu's 20,000 men?

The first thing was to arrange Lei Bo and Chen Lan to replace Ji Ling. Yuan Shu arranged the two of them to come over in the name of Lao Jun. As soon as Ji Ling received the notice, he felt something was wrong.
