The female doctor farmed the land, bought a husband and set up a separate household

"Old Fourth," Jiang Hua's heart was still aching, "that jade pendant could be sold for at least a hundred taels of silver, and you just gave it to her like that?"

"Don't worry, mom. Sooner or later, they will all be ours."

"But...but we really have no money at home now," Jiang Hua said, "What should we do with the money you need to study?"

"It's hard to say if you don't have money?" Jiang Qingzhou said, "Girl Mei is not young anymore, it's time for her to find a husband. I have a classmate named Zhang who is from Guihua Village. He has a wealthy family. Although he has a wife, he wants to take a concubine recently."

After saying that, he turned around and looked at Jiang Qingmei, who was hiding at the door, wanting to cry but unable to, and smiled gently.

"Don't be afraid, Mei girl," Jiang Qingzhou said, "My uncle's classmate is a very good person and will definitely not treat you unfairly."

For some reason, his words sounded intimidating to Jiang Qingmei, making her dare not object at all. She could only swallow her resentment silently.

"It seems that you agreed. That's good." Jiang Qingzhou said, "I have to go out for something."

"It's already dark, you still want to go..."

"It's my business," Jiang Qingzhou said coldly, "Stop interfering."

……

Back on the top of the mountain, Jiang Sining gave the jade pendant to Si Chenan, but as expected, he couldn't figure out what it was.

"But what we can conclude is that this jade pendant is very valuable." Si Chenan said, "If we ask a famous craftsman to carve it carefully, it will cost at least 200 taels."

"So, where did my mother get such a valuable thing?" Jiang Sining asked, "Did she steal it?"

"Madam, you shouldn't speculate about your mother-in-law like that."

Jiang Sining was just making inferences based on facts. She didn't have the slightest favorable impression towards her original body's extremely irresponsible mother.

"What about Jiang Yan and Qianqian?" Jiang Sining asked again, "My mother said that she found a man outside to give birth to them, but this is simply impossible. She doesn't have the ability to give birth to one in just half a year."

Si Chenan glanced at Jiang Yan and Qianqian from a distance and said, "Is it possible that someone entrusted them to my mother-in-law to raise them?"

"Why let her raise it? And why bring it to this remote little village?"

"Because they have extraordinary backgrounds."

"That's true," Jiang Sining said, "Since they were entrusted to be raised by others, is it possible that I was also raised by others? After all, she refused to even tell me my father's last name."

"This……"

Si Chenan didn't dare to jump to conclusion, but he knew that this possibility could not be ruled out.

If this is the case, my wife's life experience will become even more confusing, and since my mother-in-law has passed away, it may never be discovered.

"Madam, why don't we go to the capital and look for the county magistrate back then? Maybe he knows some clues."

I must go to the capital, but not now.

Besides, she doesn't want to know who her biological father is. If she finds him, she will have to call him dad. How troublesome is that?

"Go to bed early. We have to go to the brick kiln tomorrow."

……

Aunt Li and her group continued to dig the foundation, while Jiang Sining took Si Chenan and the two little ones, got on Uncle Wu's ox cart, and slowly headed towards the brick kiln.

Last time she asked Old Man Zhang to help burn two kilns of lime. Yesterday, the person who delivered the bricks said it was ready and asked if she wanted it delivered.

What Jiang Sining wants is not lime, but cement.

In fact, the traditional method of making cement is very simple. You just need to mix quicklime, sand and water in a certain proportion, dry them at high temperature and then crush them.

Although the quality is a bit worse, it is definitely better than lime and mud.

When we arrived at the brick-making place, Uncle Zhang, who was covered in dust, came out to greet us cheerfully: "Girl, are you satisfied with the bricks I sent you?"

"pretty good."

"That's good, that's good," said Uncle Zhang, "The lime you want has been burned and is piled over there."

Jiang Sining took a look and had to say that the old man did a really good job. The materials were carefully selected to ensure that there would not be too many stones that could not be burned through in the burned lime.

"Uncle Zhang, please help me distribute all the lime and get me twice the amount of fine sand."

"Sure, sure. It's just a matter of watering the plants." Uncle Zhang said, "It's a little more troublesome to buy fine sand. We need to go to the river to buy it."

"Remember how much silver you need, we'll calculate it later."

After receiving the lime, Grandpa Zhang immediately went to help buy fine sand, while Jiang Sining went to the market town, bought a few large clay jars and a huge stone mill, and hired an ox cart to pull all the materials back to the brick kiln.

This operation confused Si Chenan.

Lime and sand can be used to build houses, but what about water tanks and millstones?

"I know you're anxious, but don't be impatient." Jiang Sining said, "Wait until I make it, and you'll know how powerful it is."

At noon, Grandpa Zhang bought several carts of fine sand. Jiang Sining put the fine sand and slaked lime into a large clay jar in a ratio of 65:35. After stirring them evenly, he used the mold that Grandpa Zhang used to make bricks to make small cubes, and then put them into the kiln to dry on low heat.

After the water is completely dry, it is placed on a stone roller and ground into powder. Finally, it is sieved several times with coarse cloth to obtain the most primitive cement.

After taking it home, Jiang Sining mixed some mortar and laid several layers of blue bricks. After it dried, it was as solid as stone, which stunned Si Chenan.

If this thing was used to build a house, how strong would it be?

With this level of solidity and solidification speed, it would only take a few months to build an indestructible wall of hundreds of miles. By then, Daxia would no longer have to fear the cavalry from the north.

Most importantly, the manufacturing method of this thing is so simple, and the required raw materials are available everywhere!

Seeing his flushed face and the gleam in his eyes, Jiang Sining thought to himself, this guy, could it be that he is thinking of how to use cement to rebel again?

Cement is unlikely to rebel, but it can build a small country with cement...

"What are you thinking about?"

"Oh, I was thinking, if cement is used to build city walls, it can ensure peace on the border of Daxia."

Jiang Sining: ...You are an exile, a sinner of Daxia, and you still want these things?

But when I think back on it, this seems normal.

As for men, no matter when, where or what situation they are in, they will still have the country and the people in their hearts. This is almost a common problem for all men.

"Don't think too much," Jiang Sining said, "I won't easily pass on the method of making cement to others."

Si Chenan was slightly stunned. He knew that such a national treasure should not be passed on lightly.

But the thing is, he saw the entire production process and had written it down.

"Madam, aren't you afraid that I'll tell others?"

"I can't do anything about it," Jiang Sining said, "but I will give you a letter of divorce and end it all."

Si Chenan shook his head and said, "Don't worry, ma'am. I will never tell anyone without your permission. But what are you going to do with the old man who fired the kiln?"

Old man Zhang also participated in the entire process of cement production. Although he didn't know how powerful cement was, it was possible that he would try to make some himself one day.

Jiang Sining naturally had plans for this.

If you want to live happily in this world, how can you just build a house?

She had to build a small castle and a tall city wall, which would require a lot of blue bricks, so she planned to ask Old Man Zhang to help her make them.

When the time comes, let him move the brick kiln to Liuyun Village. With the huge benefits involved, Old Man Zhang will not act recklessly.

Besides, it’s just a piece of cement, not an airplane or a cannon.

Even if others don't spread the word, after a few years when the world is peaceful, she will make it herself and sell it.

In the past few days, she has stored up a lot of cement, and Uncle Li and his team have also dug the foundation.

While they were discussing how to pour the concrete tomorrow, Cao Cunzheng and his five sons came to the top of the hill with hoes and shovels in a menacing manner.

"We said that we are not allowed to build houses. Do you think this village is just joking?"

"Fill it in!"
