The cannon fodder of fast wear, she chooses to farm

Chapter 67

After an in-depth exchange last night, Yan Kejin discovered that her princess had a lot of interesting things hidden in her head.

So long as you don't annoy her.

"After I've been busy for a while, I'll accompany you for a walk. Don't you want to go to the south? How about going to Yong County as the first stop?"

Yong County is Nanning, Xu Yin knows this.

She turned to look at him: "are you busy?"

Isn't hematite mining in full swing?Such an important matter, don't you need him not to watch it personally?
"So I have to wait for a while, the princess will wait for this king, right?" Yan Kejin put a piece of fermented fish into her bowl, and met her eyes with a smile.

Xu Yin lowered her eyes, her eyelashes trembling slightly: "Actually, I'm quite busy during this time, at least I won't be free until the spring plowing is over."

"Then we'll start in early April."

As a result, in early April, it didn't work out either.

When iron ore was dug, associated limestone deposits were discovered.

When Yan Kejin came back from the mine that day, when she had a meal with her, she couldn't help sighing: "It would be great if it was all ocher, a small hill was wasted for nothing."

Regrettably, the food intake that night was half of the usual.

When Xu Yin heard the greenish white and easily broken stone, her heart moved: Could it be limestone?

Limestone is one of the associated ores of iron ore.

So, the next day, she followed the prince's carriage to the mine, recognized it as limestone, and was very happy.

This is good stuff!

Limestone can be used to make cement, and the calcined lime is matured into slaked lime.

The use of slaked lime is too extensive, the most common is building materials, and it can also be used as a fungicide. The trunk is coated with slaked lime slurry to prevent insects.

Without hesitation, she spent 500 points and exchanged a cement formula with the system.

To make cement, in addition to limestone, raw materials such as clay, quartz sand and iron ore powder are also used.

Clay is relatively easy to find.

However, the quality of the clay varied. When Xu Yin mobilized his guards to dig clay at the bank of the river and at the foot of the hillside, he accidentally discovered a mountain made of kaolin.

Kaolin is white clay, which is the most widely used clay and the best quality after being fired into porcelain.

The famous JDZ porcelain is fired with kaolin.

Limestone is available, kaolin is found, iron ore powder is readily available, so why not make cement?

It doesn't matter if there is a lack of quartz sand, the sea is right in front of you, and the worst thing is to use the gravel after washing by the waves, which is everywhere, and the composition is the same as silica, as long as it can be used.

The raw materials are ready-made, so let's put aside the shipbuilding, and Xu Yin competes with cement in the tidy back garden.

For the first time, the ratio was not well grasped, the cement made was not hard enough, and the weight collapsed when pressed.

The second time hardened too much and cracked.

Summarizing the experience of the first two times for the third time, it finally succeeded!

Xu Yin poured a certain cobblestone path in the back garden into a concrete road.

When the cement hardened successfully the next day, she clapped her hands happily: "My lord, please come!"

Yan Kejin often stays at the mine recently.

After the first batch of iron was smelted, it was forged and processed by a blacksmith who signed a death contract.

Some of them were made into iron sheets to make farm tools, and some of them were forged with thousands of hammers, and a batch of weapons were forged. The iron was cut like mud, which can be called excellent.

Today he is staying in the mansion, Xu Yin can't wait to share the good news about cement with him.

As soon as Yan Kejin arrived, she was led to the concrete road by her own princess, with an embarrassing expression on her face:
"How? Did I say limestone is useful? You still think it occupies the nest of iron ore. If you use it to build roads, the carriage will not overturn when it runs, don't you believe?"

Building roads is the first step, and she also wants to use it to boost Nanman's real estate industry.

With kaolin, building kilns and firing bricks and tiles is not a dream.

These newly-built workshops need to recruit people, and the people will earn money if they work. If they earn money, they can buy bricks and tiles. At that time, every household will live in brick and tile houses, which are much stronger than wooden structures, bamboo structures, or adobe houses. .

There are many earthquakes in the southwest area.

Although people in this era think that the earth dragon's turnaround is a punishment from heaven, they superstitiously believe that God is going to punish them, and there is no way to hide.But in the final analysis, it is a natural phenomenon, why not work hard if you can resist it?
The farther Xu Yin thinks, the more ambitious she becomes.

Yan Kejin really did not expect that with a shovel, countless pieces of limestone could be chiseled and made into cement so strong and hard.

The princess said that in addition to limestone, clay, gravel, iron ore powder, and slag that can be found everywhere in the Nanban, the cost is so low that it can be ignored, and road construction is indeed feasible.

"Then start with the prefecture city, and pour cement on the roads leading to the counties. After all the counties in the Nanban have concrete roads, build a wide road that can run horse-drawn carriages on the mountain road leading to the Central Plains. The official road cannot be built here. , let’s fix it ourselves!”

Yan Kejin was so happy that the dinner was placed on the concrete path in the back garden, and the lanterns were lit when it was dark.

He also asked the housekeeper to bring the altar of Chuxue brewed plum blossoms from his collection, saying that he wanted to celebrate with the princess.

Although Xu Yin was a little speechless, she still agreed with a broken smile.

In the twilight, the couple sipped wine, tasted delicacies, and looked forward to the bright future where cement roads lead to every corner of Nanban.

Xu Yin doesn't drink much, and she can get completely drunk after drinking a glass of red wine, let alone plum blossom brewed with a higher alcohol content than red wine.

Before the dining table was removed, the stamina of the wine picked up, and she asked Yan Kejin when she would take her around Nanman with her cheeks pouting out her moist red lips.

"I want to explore every county in Nanban. If you don't take me there, then I will go by myself."

"Go! When the king arranges the affairs at hand, I will go with the princess!"

"I want to go to the beach, collect shells, eat seafood, walk barefoot on the beach..."

"……it is good."

Although I don't understand what fun it is to walk on the beach barefoot.

"I also want to go out to sea by boat and catch a lot of seafood..."

"it is good."

"I still want to..."

"These things will come true. Now, it's time to think about me."

He hugged his wife in a hug, and strode back to the room.

Fortunately, after the house was completely renovated, a common bedroom was set up for the husband and wife, so it will come in handy.

……

After King Jinnan had settled down the affairs at hand and wanted to take the princess on a trip, it was Xu Yin who said to wait.

There are no official roads in the Nanman territory, and the roads in the counties are all opened by the government's corvee. The main counties do have roads, and the roads are relatively smooth when there are more people walking, but more roads are small trails. The kind that a carriage can't run.

Now that there is cement, Xu Yin is not in a hurry to go out, let's wait until the cement road from Fucheng to Yong County is opened.

Before the arrival of the Dragon Boat Festival, she wanted to make the compass.

Magnetite is indeed associated with hematite, and the reserves are not large, but it is more than enough to make a compass.

With the magnetism, Xu Yin couldn't help but want the whole solar motor to come out.

The Nanban water system is well developed, and with electric motors, hydroelectric power can be easily realized.

When electricity is connected, mining machines and road rollers that can make industrial production more convenient, as well as spinning machines and looms that improve people's livelihood are no longer just dreams.

Thinking about it, she cheered up, she felt a little floating!
