Tang Dynasty: The beginning of the game is to touch the Princess Changle

There are still 12 days before Su Chen and Changle's engagement party.

After Empress Changsun recovered and the engagement was confirmed, everyone became active.

Li Chengqian told Su Chen the whole process of the snowflake salt incident in Chang'an a few days ago.

He also said that the Cui and Wang families of the Five Surnames and Seven Families were the worst deceived and bought more than 80 million kilograms of salt to store at home.

Everyone praised Su Chen and admired him.

"Brother-in-law, don't sell that ice cube, or give it to someone else."

"Now there is a big business that needs to be handed over to you."

Su Chen couldn't stand them saying "The national teacher is powerful, we admire him" and so on.

When Li Chengqian heard it, he thought: No, selling ice cubes costs more than 30 strings a day.

This is a huge sum of money for him.

"Brother-in-law, I can let someone else take care of the ice cubes. I can sell more than 30 guan a day!"

Su Chen listened, looked at Li Chengqian, and then looked at Changle.

There is a gap between these two siblings. More than 30 guan a day? The money for two kilograms of wine?

Su Chen immediately stood up and changed his seat, sitting with Li Chengqian.

Putting his arm on his shoulder, he said earnestly:

"Brother-in-law, have a bigger vision and a longer-term perspective."

Su Chen said, while gesturing outward with his other hand, and then continued:

"30 guan a day can't make you rich, nor can it improve the lives of the people. What's the point of it?"

It doesn't matter if Li Chengqian doesn't understand, Li Shimin understands.

"Boy, this business you are talking about can make us rich and improve the lives of the people. Are you serious?"

Li Shimin looked at Su Chen excitedly and asked.

"It's still early for dinner. Let me take you to see it. By the way, why didn't the other three uncles come today?"

Su Chen found that only Cheng Yaojin, Yuchi Gong and Changsun Wuji came today, and the other three did not come.

"They have something to do today. They will come together next time." Li Shimin answered casually.

Su Chen nodded, "Let's go. I'll take you to visit this manor. I have made two things recently."

"Our manor is renovating the old house!"

...

Su Chen led everyone to the red brick factory first.

Everyone was confused by the piles of neatly stacked mud blocks. Many villagers were busy all the time. Are they playing with mud?

"Su Chen, what's the use of this mud block?" Changsun Wuji picked up a brick and pinched it, and asked.

It was also a coincidence that there were two roads from the manor to the red brick factory, so they first came to the place where the bricks were dried.

Su Chen smiled and replied:

"Uncle Auxiliary Machine, this is a semi-finished product. Let's go over there to see the finished product."

Su Chen pointed to a place and led them over.

"Master!"

"Master!"

Su Chen smiled and nodded in response to the villagers.

There are only about 200,000 bricks in the finished product area now, and they are still being transported out, because the villagers have begun to demolish old houses and build red brick houses.

"This is the finished red brick." Su Chen picked up a brick to show everyone.

"Oh, red brick? It's much bigger than blue brick. Su boy, how much does this red brick cost?"

Changsun Wuji is half a businessman and is more sensitive to costs.

Su Chen thought about it, he didn't seem to have carefully calculated the cost, "Uncle Auxiliary Machine, how much does blue brick cost?"

"Three pieces of blue brick for one cent."

Changsun Wuji didn't even have to think about it and answered directly.

Su Chen frowned, "How many blue bricks can a worker burn in a day? How much is the daily wage?"

Changsun Wuji also frowned and thought.

"It's not easy to get clay. Blue bricks need to be fired for ten days to half a month. If you count the labor, it's probably 5 cents per blue brick."

Su Chen nodded and smiled.

"The cost of red bricks is about 1 cent for 10 pieces. The materials can be found everywhere. Have you seen those brick kilns?"

"One kiln produces 12,000 pieces. It is fired for three days. It is fired with coal. The red soil you see is the main raw material of red bricks, and the coal slag is the ingredient."

Everyone opened their mouths wide and couldn't believe it.

Then Su Chen took them to the cube-shaped red brick wall.

"Uncle Cheng, try to hit this wall with this."

Cheng Yaojin said nothing and hit the middle of the wall with a hammer. The wall was full of debris and there was a loud noise. The wall was intact.

"Why is this wall so solid?"

Changsun Wuji and Li Shimin walked up, touched the wall, and also used their fingers to pick the gray stuff in the brick seams.

They also knew that it was the stuff between the gaps that played a big role in making the wall strong.

But they didn't know what it was.

The blue bricks used in the Tang Dynasty were mostly made of mud and lime, and the brick joints were grayish white.

"What is this?"

Li Shimin pointed at the cement between the brick joints and asked.

"That's cement, and it's as hard as iron after solidification."Su Chen replied with a smile, and pointed to the cement pier next to him.

Cheng Yaojin didn't need anyone to command him, and he was about to hit the pier with force. Su Chen was shocked and hurried forward to stop him, saying that the reaction force would hurt people.

But Cheng Yaojin still tried it, and as expected, sparks flew and his hands were numb.

"This cement has many uses, such as building roads, houses, city walls, and dams. It can do everything. Uncle, do you think this is a big business that benefits the country and the people?"

Li Shimin heard it, and he was like a chicken blood, and he stepped forward to grab Su Chen's hand: "A big business that benefits the country and the people, my dear son-in-law, hurry up and do it."

"Su Chen, what did this cement look like before?"

Su Chen couldn't say this, so he took them directly to the cement factory.

Before they arrived at the cement factory, they were stunned by the road.

This is a cement road built not long ago, one foot wide and three inches thick, a flat piece, with an expansion joint every four meters to prevent thermal expansion and contraction.

"This is a road made of cement. It is not afraid of rain or carriages."

Su Chen pointed to the flat road under his feet and said.

"But the current cement production is low and the production is complicated, so the price is high."

In the distance, several cows were pulling cement towards them. The cement was transported there to build houses.

"Is the road where the carriages are running called a road?" Li Shimin murmured.

Su Chen smiled after hearing this, 'It's the Marxist road, so it's called a road. '

Everyone stomped their feet hard, Cheng Yaojin and Yuchi Gong directly took out their daggers and scratched on the road.

Li Shimin and Changsun Wuji looked at the flat cement road, thinking.

They have been living in Chang'an City and are very familiar with the road environment in Chang'an. Whenever the rainy season comes, many roads are muddy everywhere.

It would be great if Chang'an City could build all these cement roads!

The two looked at each other, and Li Shimin smiled bitterly and shook his head.

The treasury finally had some money, and it was not worthwhile to use it to repair the road.

He knew that this kid was not interested in the emperor and would definitely rip him off.

Li Shimin decided to wait until Su Chen and Changle got engaged, and then make his identity clear and appeal to his emotions and reason, hoping that Su Chen would not make money from him.

"Master! Hello, distinguished people!"

Everyone nodded in response to Su Chen.

After Su Chen, Li Shimin and others arrived at the cement factory, they asked someone to fill a basin of cement.

Su Chen mixed it with water and sand and gravel on the spot, and after mixing it evenly, he clapped his hands.

"This is the process of cement formation. First it is ash, then this kind of concrete, and finally it solidifies and becomes that pier."

Li Chengqian wanted to squat down and grab a handful to see, but was pulled up by Su Chen.

Now everyone understood that this is indeed a big business that benefits the country and the people, and there is a large demand.

"Brother-in-law, I've done this. How do you think I should do it?"

Su Chen thought for a while, "Brother-in-law, if you only do business in Chang'an, you can do it alone. If you want to do business in the whole Tang Dynasty, you can't do it alone. This thing is not convenient to transport over long distances, so you can only set up a factory nearby."

"Let's find a few uncles to do it together. Let you make some money first. I will announce the production process in three years. But I will set the price. I can't just focus on making money."

Li Chengqian nodded, "No problem, I will discuss it with a few uncles then."

Su Chen set the price: 5 wen for 10 pieces of red bricks, 800 wen for 100 kilograms of cement.

Li Shimin and Changsun Wuji nodded silently, looking at Su Chen with admiring eyes.

What a good child!

Changsun Wuji also wants to marry his daughter!
