"Your Majesty, with all due respect, building the city wall now is definitely the next policy. Even if, as His Majesty said, the walls can be repaired within six months. However, the food consumed is huge, and it is better to save this food in order to last more time when Tang Yunbi besieges Chang'an.

Moreover, with the existing city wall alone, Tang Yunbi categorically could not storm it, so he could only choose to besiege the city to exhaust our food. ”

Su Jingsheng found Tang Wenyuan again to analyze the pros and cons of building the Great Wall. In his opinion, Tang Wenyuan made an extremely stupid decision, if he really repaired it, he couldn't even repair it a foot high, Tang Yunbi would call him.

Tang Wenyuan buried his head in writing the basic engineering teaching, and frowned slightly, "Master Su, what if the Tianchi Kingdom took the opportunity to attack?" Tang Yunbi didn't dare to attack alone, but with the addition of Tianchi Kingdom, the ending would be different. Therefore, this city wall must be repaired, and as for the food problem, I will solve it, so Master Su does not have to worry.

In addition, I only have 5,000 acres of fertile land in my hands now, if Master Su can find another 5,000 acres for me, six times will be without worry. ”

"But Your Majesty...... How to build this wall so that it can be built in six months? ”

Tang Wenyuan put down his pen, took Su Jingsheng to the courtyard, and pointed to the concrete blocks that had been made in advance, "Look, this is what is going to be used to repair the city wall." ”

Concrete is an extremely hard building material that becomes more and more rigid over time. Molded concrete buildings are difficult to break apart, even with a sledgehammer, let alone a concrete wall of this thickness.

"Master Su, there is a hammer here that you can smash and try."

Su Jingcheng frowned slightly, picked up the sledgehammer and smashed it symbolically, after all, an old bone is easy to flash to the waist if you smash it hard.

When the hammer went down, his hands were numb, but the concrete block was undamaged.

"Your Majesty, what kind of brick is this?"

"It's not a brick, it's called a concrete block. It is made of sand, gravel and cement. I don't need to talk about sand and stones, there are a lot of them next to the big dirt hill on the outskirts of the city, which is enough to repair the city wall.

Cement is made by mixing lime with soil and adding special materials, and I have sent people to find a large amount of limestone on the outskirts of the city, and I have dug caves and fired them overnight.

There is no need to burn bricks, no need to build walls, all we have to do is to produce a large number of wooden formwork that can fix the shape, does Lord Su think six months is enough? ”

"This ......"

Su Jingsheng is not very proficient in architecture, he knows lime, but he doesn't understand what cement is. However, if it is really as Tang Wenyuan said, there is no need to build walls, no need to burn bricks, and even do not need to travel long distances from all over the country to transport materials, then it is completely possible to build a city wall in six months.

And Tang Wenyuan is so confident that it can be repaired in six months because after the last system update, there are pre-updated items in the mall list.

You can see what's coming out next, but the icon is dimmed and can't be purchased.

These items include steel bars, water pumps, rubber, and fertilizers.

The water pump is the first item to appear in the mechanical category, and there is no need to think about it, the price of points will definitely be surprisingly high.

What Tang Wenyuan didn't understand was that the system update didn't play cards according to the routine at all, shouldn't he just brush a steam engine at this time to liberate productivity.

The role of the water pump, at present, Tang Wenyuan only thinks that it is more convenient to irrigate the farmland, and has not thought about other uses.

The reason why craftsmen also make steel bars is, on the one hand, that the Wen Dynasty did not have strict building regulations, and the steel bars you use must be qualified, and the seismic level must be how many levels, make do with it, and play a role in stability.

On the other hand, the speed at which you can earn points is limited, and there are too many places to use them in the next six months. Only the most reasonable possible use of limited credits.

Grain seeds must be replaced, as is cement. As for the stones, sand and steel bars, they should be appropriately used on the spot, so as not to lead to insufficient points.

But Su Jingsheng had a headache, no matter what, he had to help Tang Wenyuan think about retreating. He has 100,000 soldiers and horses in his hands, and last time he told Tang Wenyuan that he could use 20,000, the actual situation is that he has to transfer some of them to Los Angeles in advance.

Slowly hoarded grain and grass in Los Angeles and slowly built the city walls. If Tang Wenyuan insisted on defending Chang'an City, then Luocheng would have at least a year to prepare. At the same time, he also plans to send some officials over to let the government in Los Angeles be slowly established.

Su Jingsheng's approach is a bit like the capital and the capital during the Ming Dynasty.

After all, the century-old foundation of the Wen Dynasty can't be messed around like Tang Wenyuan, right? You have to leave yourself some way out.

Although Su Jingsheng didn't want to believe what Tang Wenyuan said, as a courtier, he had to cooperate, Tang Wenyuan was no longer the stupid emperor he used to be.

…………………………………………………………………………………………………………

The Tang Yunbi incident still had an impact on Chang'an City, and many wealthy businessmen had already left in a hurry. Tang Wenyuan imposed a harsh policy on merchants, requiring wealthy merchants living in Chang'an to pay 10 percent of their property if they wanted to move out.

Troubled times should be used to re-enact, and businessmen, with their keen sense of smell, feel in advance that troubled times are really coming.

Therefore, he paid 10% of his property and left Chang'an City.

In the event of war, the capital will either be the safest place or the most dangerous. Because this is the place where all the invaders want to set foot the most, the capture of Chang'an means the complete fall of the Wen Dynasty.

For most people, life hasn't changed much.

The imperial court was still recruiting workers, and the streets of Chang'an were still in full swing. Everyone has lived in Chang'an for generations, and has a complex of relocating to a safe land, and as a last resort, even if they encounter that kind of slaughter of the city, few people are willing to travel thousands of miles and change their living environment.

The Wen Dynasty has ruled for more than a hundred years, and everyone has a sense of dependence, or belonging, in the face of the Wen Dynasty in their hearts.

You see, isn't the imperial court already about to start building the city walls? As long as the city wall is built and protected by a double city wall, Chang'an City will become the safest place.

As the sun set, the queue for labor registration reached all the way outside the city gate.

There was a hurried sound of horses' hooves, and the herald galloped forward on horseback.

"Get out of the way, get out of the way, 100,000 urgent, 100,000 urgent!"

The urgent report in his hand was handed over to the city gate guards, who changed their horses and went straight to the palace.

The transmission layer by layer finally reached the ears of Tang Wenyuan, who was writing a book in the Funing Palace.

"Your Majesty, the crown prince of Tianchi has personally led 20,000 troops to Gancheng, and a special envoy has been sent to repair a book."

Tang Wenyuan suddenly stopped his pen and frowned, "The speed is coming." ”
