Chongzhen Undergraduates

According to Yan Yingyuan's vision, Xuzhou will cost a lot of money, and the project will be huge.Because the current Xuzhou City is almost a new city, and even the city is just a framework.

No wonder the entire three towns in Jiangbei surrendered instead of standing up. With the pissing nature of these warlords, even if they can't be defeated, they won't all surrender overnight, unless they are all cowards like Liu Zeqing.

In the field battle in Jianghuai, Xuzhou can't hold it, who can beat the golden Tartars? If you don't surrender, you will die faster.It is true to say that soldiers are not afraid of death. Since they are soldiers, they live with their heads pinned to their waistbands.

But to say that all soldiers are willing to die is nonsense.Why don't you do the death thing? Whose life is not life.

Of course, there must be fear of death in it.But these people turned around to fight Daming, which shows that most of them were not afraid of death.

"How much money is needed and how much time is needed." Of course, building fortifications takes time, but more importantly, it takes money.

"One year, at least 20 taels." Yan Yingyuan gritted his teeth.

"I brought you 20 engineering soldiers, and escorted a full [-] dan of cement, and they are on their way."

After all, cement is not food, it just needs to dig a few more kilns.From the end of last year to last month, [-] engineering soldiers did nothing but burn cement and learn construction.

The inventory accumulated for more than half a year was basically pulled over by Zhu Youjian, and he also transferred [-] engineers by the way.

"What is cement?" Yan Yingyuan and the whole room were puzzled.

"This material can replace clay. It can be used as a joint of blue bricks or as a piece of its own. It is harder than solid stone, and the construction time is faster than that of blue bricks."

"Is there all this?" Everyone obviously didn't believe it.

"Go, call Fan Laogen in."

Both Fan Laogen and Che Dahammer followed Zhu Youjian all the way north as forwards, and the army of engineers was still on the canal.Hearing the emperor calling him, he also panicked.

"Give Commander Yan and the others to build a wall in this yard, and let them see the usefulness of cement."

Zhu Youjian pointed to the open space in the yard, and by the way, nuzzled, meaning it's up to you.

"Hey!" Fan Laogen was overjoyed, this is a good time to express himself.

I saw that he brought a dozen people with him, carrying a few baskets of things wrapped in kraft paper, and a dozen baskets of gravel.Sand and gravel were poured on the open space, and a kind of gray powder, like firewood ash, was poured from the basket onto the gravel.

Everyone disagrees, what can this pile of powder be used for?The difficulty is that it is used to bond green bricks with quicklime?

Two carpenters quickly built a hollow, two-foot-thick box.Fan Laogen began to pour the already-mixed cement mortar into the box, added bamboo strips layer by layer, and stirred the mortar in the box with an iron rod.

The wooden box was quickly filled, and today's technical demonstration is over.

(Don't underestimate the bamboo stem strips, it is the best substitute in the absence of a large number of steel bars.)

Yan Yingyuan was taken aback, thinking: This is it?

Zhu Youjian seemed to understand his thoughts, and said with a smile: "Don't worry! See you in three days."

In the next three days, Zhu Youjian inspected some administrative work in Xuzhou, but did not ask about the military camp.

On the fourth day, the formwork in the headquarters yard had been removed.A thick wall was exposed, Fan Laogen was standing aside with a big hammer, Yan Yingyuan and others were curiously touching the concrete wall with their hands.

"It still looks hard, it should be harder than blue bricks." Yan Yingyuan commented.

"You hit it with a hammer." Zhu Youjian smiled.

"Can you really smash it?"

"Smash it, smash it hard."

Yan Yingyuan was a thief, he made a fuss about a staff officer, and the staff officer understood.A strong man walked up to the concrete wall with a sledgehammer.

Zhu Youjian didn't panic at all, the [-] cm thick concrete wall, it's no wonder you don't get exhausted.

"Boom!" The strong man was too strong, and the first hammer hit the middle of the wall.His arm went numb from the shock, and a small hole appeared in the cement wall.

After more than a dozen hammers, the cement wall did not move at all, but the small hole in the middle was a little bigger, and there were not even any larger pieces under the hammer, only some broken pieces.

The big man smashed continuously for a long time, panting with exhaustion, and finally smashed a big hole in the middle of the concrete wall.However, the cement wall as a whole is fine.

The big man turned and began to smash the corner of the wall, so that a larger fragment flew out.

"Mr. Fan, right? Come on, please sit down." Everyone in the room was dumbfounded when they saw Yan Yingyuan shamelessly fawning on Fan Laogen.

"Why are you stunned? Hurry up and serve Mr. Fan some tea. Alas, the young man just doesn't have any discernment." Yan Yingyuan scolded the guard.

Zhu Youjian shook his head, this was the first time he was directly ignored since he went south to reveal his identity.

It was the first time that Fan Laogen was called Mr., and his face was blushing nervously. He only dared to be half of his butt, because he was the only one in the room, and he was pushed on the chair, even the emperor was standing.

"Actually, it will be harder after seven days of curing."

"Is it harder than now?" With the current hardness, Yan Yingyuan is already very satisfied.

If this was a wall of green bricks, a large part would have collapsed long ago.The reason why the city wall is strong is that there is a layer of rammed earth inside the blue bricks, which resists the impact as a whole.

"How about it? You don't need to make bricks, you only need sand and gravel, and you can start working on the entire foundation at the same time. If you have enough people, you can build a height of three feet in seven days and a foot in a month."

Yan Yingyuan nodded excitedly like a chicken eating rice: "There are enough people, enough."

Building a city in a month is undoubtedly a miracle in this era.

Zhu Youjian calculated that as long as Houjin was unable to attack Xuzhou within half a year, with sufficient cement supply, Xuzhou's fortifications would be completed.

The rest depends on how long Shandong can carry it.

Chapter 2 Fifteen: The Thief in the Elm Grove

After several days of deliberation, Zhu Youjian finally decided to complete a medium-sized city covering an area of ​​[-] mu in Xuzhou in accordance with the requirements of Yan Yingyuan and others.

According to Yan Yingyuan, the bigger the city, the more scattered the troops defending the city.The bigger the city, the better.In a city of 10,000 mu, it is just right to have a population of [-]+ in it.

In addition, two small bastion-style cities were built on the spot in Taierzhuang and Xiaoxian to play a diversionary role.The height of the city is one foot and one, and the height is already equal to that of Nanjing City.

A foot-thick cement wall was erected on the outer wall, the inner wall was built with stones, and the middle was filled with rammed earth.

Three more underground sewers were built in Xuzhou City, leading directly to the Yellow River waterway to prevent water accumulation.The important buildings in the whole city, such as the granary, the headquarters, and the gunpowder depot, were all raised by two feet.

The entire construction period is planned to be completed in half a year, and the Ministry of War will allocate 30 taels.

Yan Yingyuan especially emphasized that, counting all the garrisons, there would be [-] to [-] laborers without recruiting young and strong people, and it should be no problem to build it in half a year.

From Zhu Youjian into Xuzhou City, on the official road leading to Caozhou (Heze) and Linyi, there are more than a dozen fast horses galloping northward.

In Fan County at the junction of Henan and Shandong, there is a well-known place called Yuyuan Village.At the entrance of Yuyuan Village, there is a green and tall old elm forest. Every late spring, the elm trees are rippling with the wind, the elm money shakes down, and the trees grow into a forest.After a long time, the elm forest stretches across the banks of the Yellow River for more than a hundred miles, and extends to the Caozhou area of ​​Shandong Province on the south bank of the Yellow River, which is very spectacular.

In spring, when the harvest is green and yellow, elm money is the food that can save lives; in the elm garden, there are towering trees, tall trees and dense forests, surrounded by water pools. Once a person enters the elm garden, it is like a fish entering the sea. There is nothing we can do.
