In the Funing Palace, Tang Wenyuan was communicating with several skilled craftsmen in the palace.

He drew down the drawings of the shuttle loom (Jenny machine) in detail, preparing for a revolution in the textile industry.

The steam engine could not be made under the current conditions, so it had to settle for the second best thing and make the Jenny engine first. Compared with ordinary textile machines, the efficiency of Jenny machines is as much as seven or eight times higher.

Several skilled craftsmen looked at the drawings and studied them for a long time, and came to the conclusion that they could try to make it, and the only difficulty was the conveyor belt.

"Let's make it with beef tendon, it shouldn't be a problem. By the way, how much do you know about the laws of steelmaking? ”

"Back to Your Majesty, I have been making steel for generations, and I have a deep understanding of the method of steelmaking."

"Can you make a steel bar as thick as your index finger and a foot long?"

"It's a bit difficult, and you need to use the welding method."

"You make a few first, I'll see, if it's feasible and needs to be made in large quantities, I'll find someone for you."

"Commanded by humility."

"Do any of you know how to build walls?" Tang Wenyuan continued to ask.

"Your Majesty wants to build a wall?"

"How long will it take to rebuild the walls around the perimeter of Chang'an City?"

Several craftsmen stared wide-eyed, as if they had heard some terrible secret.

"Your Majesty...... The city wall of Chang'an City, which cost 100,000 laborers, took three years to complete, and now the national strength is declining, and the city wall is wanted to be rebuilt...... I'm afraid it will take five years, if not longer. ”

"Don't jump to conclusions, you help me find more people with experience in masonry, and in six months, I will rebuild a city wall within six months."

"Your Majesty...... This...... Are you kidding? For six months, he couldn't even burn the bricks needed to build the wall. ”

"Who said you need bricks to build a wall? Okay, just get me people, and I'll teach them how to build walls myself. Little dog, inform and let the ministers go to the Jinluan Palace to go to court. ”

When Tang Wenyuan got up this morning, he found that the system mall had been updated again.

And this update made him thoroughly understand the power of the system.

Science and technology: cement, 1 point a ton, sand, 1 point a cube, stone, 1 point a cube.

How many traversers can't figure out how to make cement, Tang Wenyuan is good, and he can directly exchange it with the system.

And Tang Wenyuan found that this kind of large number of consumables are very cheap to exchange points.

For example, soap is only 1 point.

Tang Wenyuan roughly calculated. The inner city of Chang'an City is five kilometers wide from east to west and six kilometers long from north to south.

If you want to rebuild the outer wall, you need to be at least six kilometers wide and seven kilometers long, the width is not too wide, four meters is enough, and the height is about eight meters, if time permits, of course, the higher the better.

In this way, about 800,000 cubic meters of materials are required to build a concrete wall.

In ancient times, the construction of city walls was slow, on the one hand, the firing of raw materials was too slow, and on the other hand, the transportation of materials also took most of the time, and the masonry was far more than the time spent on watering.

In the case of sufficient raw materials, as long as the manpower is sufficient, it is definitely not a problem to build a city wall in six months, and Tang Wenyuan is about to go to the court to discuss this matter with the ministers.

Today was supposed to be a day off, and the ministers were resting at home. Suddenly, I received news that the emperor asked the ministers to go to the court. One by one, they scolded in their hearts, and rushed to the Jinluan Hall with great reluctance.

In fact, this is also to blame Tang Wenyuan, he still lets Jiang Fengyi control the government, he rarely goes to the court, and every time he appears in the court, something will happen.

This made the ministers very distressed.

With what happened last time, Tang Wenyuan is no longer pretending to be stupid, and now there are more ways to get points, and it is not enough to get those points by pretending to be stupid.

"Ladies and gentlemen, I plan to rebuild the city walls around Chang'an City, I don't know what you Aiqing thinks?" As soon as this statement came out.

The ministers were dumbfounded.

I used to play stupid, but this time I'm really stupid?

Build a wall? Isn't it possible to do it in three or five years?

"Your Majesty, are you joking?" Su Jingsheng stood up and asked.

"Do you think it's like you're joking? Six months, only six months for me to build a wall and come out. ”

"Your Majesty, don't say it's been six months, with the current situation of my dynasty, I may not be able to cultivate it in six years!"

"Your Majesty, if you are worried about Chang'an City being broken, it is better to move the capital to Luocheng."

"Your Majesty......"

Tang Wenyuan waved his hand, "You Aiqing don't need to say much, I only need six months, if the city wall can't be repaired in six months, I will take you to move the capital together!" What I need you to do now is donate money. However, rest assured, this money will only be used to build the city wall. Okay, Su Aiqing, take a stand. ”

Although Su Jingsheng didn't know what medicine Tang Wenyuan was selling in the gourd, he still cooperated very much.

"Wechen is willing to give 500,000 taels." He said this a little reluctantly.

It's not that I'm afraid that Tang Wenyuan will investigate how he got these 500,000 taels, the Wen Dynasty has already reached this point, and Tang Wenyuan doesn't care if you are greedy or not.

Su Jingsheng just felt that Tang Wenyuan's words were too fake, and he would build a city wall in six months, so could he go to heaven and invite the immortals down? Kill him and don't believe it!

Hua Tianxiong saw Su Jingsheng's statement, and he also stood up, "Your Majesty, Weichen is willing to give one million taels." ”

The other ministers saw that the prime ministers on the left and right were following to donate money, but they had no choice, and they all said that they wanted to donate money.

Although the Tang Yunbi incident did not have much impact, everyone knew in their hearts that Tang Yunbi would definitely attack Chang'an, it was just a matter of time.

In the face of family and national affairs, these ministers are still very united.

The Ministry of Industry Shangshu stood up at this time, "Your Majesty, Weichen wants to hear how Your Majesty will repair the city wall within six months, how high and how thick it will be?" ”

"How to repair it, you will know when it is repaired, but this wall is at least one and a half zhang wide and three zhang high. And I promise that as long as the city wall is repaired, the catapult of the Tianchi Kingdom will be unscathed if it smashes on the city wall! ”

Tang Wenyuan didn't explain much, and he didn't know how to explain it, he had to think of a way so that everyone didn't doubt the source of those materials.

So after going down to the court, Tang Wenyuan took the night rose alone and rode to the outskirts of the city.

There is an earthen mountain in the east of Chang'an City, which is not small. Tang Wenyuan directly exchanged 10,000 cubic meters of sand and 10,000 cubic stones next to Tushan. It sounds like a lot of money, but it doesn't even add up to one-fifth of the dirt mountain.

Of course, when the sand and stones were piled out, Tang Wenyuan temporarily branched out the night rose.

After the sand and stones were ready, Tang Wenyuan instructed Night Rose to send people to dig a cave on the dirt mountain overnight, digging as big and more as possible, and after digging, he should send someone to strictly guard it, and no one was allowed to enter.

These caves are where Tang Wenyuan intends to store cement.

This is just to solve people's doubts about the source of the materials, and after the start of construction, Tang Wenyuan can take advantage of the night when no one is paying attention, directly stack the materials next to the city wall, so that even the time for transporting materials is saved.
