Lu Yingfang hadn't had time to greet this cheap son yet, and the people in each room knew that he was back, so they all hurried over to the main hall. It's also good to have a small room, and you can gather everyone in a few steps.

Everyone saw the salute one by one, and Lu Yingfang wanted to let the fourth child rest, but he said that it was okay. In the end, Lu Yingfang left the eldest child, the third child and the fourth child to have a meeting, and the rest of the people went back to their rooms.

Lu Yingfang didn't know much about Youzhou, so she could only rely on the fourth child to provide her with information.

Lu Yingfang originally planned to save some merit points and find a way to make cement directly from the time-traveling novel, but there was relatively little description of how to invent cement in the time-traveling novel she bought, and she didn't want to toss too many times, after all, their every move to Youzhou was watched! There is not so much labor at home for her to toss.

Therefore, she planned to buy the cement formula directly from the system to ensure that it could be successful at the first time, so that it could be conveniently dedicated to General Song Guan.

Cement can be described as a weapon to defend the city, as long as the city on this side of Youzhou is strong enough, it can also ensure the safety of one side. The point is that their Lan family is also in Youzhou, which is very important.

When she was ready to buy it, when she got the cement recipe, she couldn't help but feel a little discouraged.

The raw materials of cement are limestone, clay, iron-making slag, and mature lime firing technology. Mature lime firing technology, what the hell is that? She doesn't understand!

- Dear, you can buy lime firing technology in the mall, a hundred merit points, you can have!

Lv Yingfang: ......

Secondly, you have to find clay everywhere, and most importantly, where is there so much iron-making slag? Iron is a tube product, what does this mean? There is little iron ore! Is there an iron mine in Youzhou?

- Dear, I can tell you where there is clay and iron ore near Youzhou! You can exchange 200 merit points!

Lv Yingfang: ......

The second is the issue of temperature, and you have to find coal. Charcoal can be used as a fuel and the furnace temperature can reach 1300 degrees Celsius, while with coal it can reach 1800 degrees Celsius.

- Dear, I know where there is coal, a hundred merits, you are worth buying.

Finally, the bellows had to be invented, which was the key to the temperature rise.

- Dear, spend a hundred merit points to buy the production map of the bellows, it is absolutely easy to use, absolutely cheap!

The conclusion was that, with the well-established lime firing technology, she had to buy five more times from the system to ensure that cement would be invented. And she only has 200 merit points left.

She had to grit her teeth and buy the bellows blueprints, and as for the clay and coal, let General Song find it himself!

If it is still unsuccessful by then, she can only buy the mature lime firing technology.

Soon, Lu Yingfang found a problem again! It turns out that cement must be reinforced before it can be used for construction, and it is easy to crack if there is no steel bar directly with cement.

The cement to build dams and high cities through the novels I watched before was completely unrealistic! She can't invent steel bars, and bricks with cement are also a good choice. It is better than them ramming the walls with earth.

So not only did she have to invent cement, she had to invent bricks!

So Lu Yingfang had to buy another method of making bricks in the system. Her eyes widened when she finished reading it.

The clay used to make bricks is exposed to the wind and sun for up to half a year, and then it is crushed and sieved by hand, leaving only fine pure soil. After adding water, trample with ox force, and it will take about one to two months to make the bricks completely dry. I read a travel novel before, and it seems that it will be produced in ten days? Ahhh

In this way, Lu Yingfang bought the cement square, bellows drawings and brick squares, and her merit value was left with eighteen left.

After Lu Yingfang re-copied these recipes, he handed them over to the fourth child, and asked him to hand them over to General Song Guan himself.

As for what the Lan family should do in the future, she had already thought about it.

At the beginning, she came up with recipes for making ice, gourmet recipes, and even stoves for making iron, all of which were thought to have been obtained from ancient books. As long as she is engaged in food and invention in the future, it will be considered to be obtained from ancient books.

Wouldn't it be clear that there are infinite possibilities on her side. Whether it is people in the government or robbers and bandits, they will all target their Lan family.

She felt that even if she offered the cement recipe and the brick recipe, the emperor would not restore the title of the Lan family because of this, after all, how could the emperor's order be changed overnight? Then it is even more difficult to "lead the Lan family to the top".

Power doesn't want to be on the sidelines!

It's useless to become the richest man in Tai'an, you can't keep it!

Only fame can make a fuss.

She hurriedly read hundreds of novels and finally decided to write an article! Earn merit points by writing novels, you don't have to work hard to move the crowd, it's safe and convenient, hehe.

Lu Yingfang's original calligraphy is good, and she has also practiced calligraphy for many years in the 21st century, the two are integrated, and her current manuscript is taken out, even the Lan family may not recognize it.

Lu Yingfang is very happy, fortunately, the paper has been invented now, and she does not need to invent it. Although the invention of paper can obtain the gratitude of the whole world, it is too ostentatious and does not fit their current status as ordinary people.

"I decided to open a bookstore and let these Confucian scholars in Youzhou donate books, and then let the scholars read books for free in another room. Then run a "monthly magazine" and let everyone contribute. Lu Yingfang's words were undoubtedly heavy**, and the three of them were stunned.

Lan Rongzhuan almost jumped up, and the little eyes on his fat face widened: "Mother, are you joking?" ”

Books are precious, and my mother still wants the local Confucian to donate books? I also want to read books to scholars for free.

Running a monthly magazine? Will anyone contribute? Those scholars think very highly of themselves, how can they be willing to write a book? When everyone heard the submission, they thought it was a script.

Lan Rong turned calmer, he thought for a while, and then spoke: "Mother wants to open a bookstore in Pingyang Mansion to gain prestige?" "The cost of opening a bookstore is not large, if you can say that the great Confucian donates books, the cost of investment will be less.

Lu Yingfang nodded, opening a bookstore to facilitate writing novels and obtaining merit points. She originally wanted to submit her manuscript and find a bookstore to work with. But she wants to reveal a lot of things in the novel, so she is afraid that she will be cut off by the bookstore.

Besides, the Lan family can't sit and eat, they can always make a living. It's too tiring to open a restaurant, and it's easy to be found. Isn't it common for people to pretend to be poisoned after eating your food?

Opening a beauty shop and making skin care products are inseparable from the word secret recipe, which is easy to be coveted. Besides, we have to pull local officials into the shares. There are a lot of troubles, and the money earned is still remembered, and the merit value is not obtained.

She doesn't expect to make a lot of money now, as long as the bookstore is enough for the Lan family's daily expenses, she can earn merit points!

Lan Ronghe shook his head: "Mother, regardless of whether it is feasible to read books for free, it is really difficult for Da Confucian to donate books." ”

Lu Yingfang said with a smile: "Everything is difficult at the beginning. The best school in Youzhou is Mingde Academy, and I want to meet Xiao Yuanmao. ”

Youzhou has been relocated in the city since it was slaughtered ten years ago and after General Song Guan seized the city. Centennial College was burned down to a few broken walls. Xiao Yuanmao was the emperor's teacher when he was young, and he volunteered to come to Youzhou to rebuild Mingde Academy and became the head of the academy. This person has quite a character, the former emperor was very naughty when he was young, and often played tricks on other teaching masters. Xiao Yuanmao was once tricked and directly whipped the prince, but the emperor not only did not blame him, but also said that he smoked well. Since then, the former emperor has been studying honestly.

After Xiao Yuanmao built Mingde Academy, he vigorously carried out the cause of education, and some children of high-ranking officials wanted to study in the academy. At first, Xiao Yuanmao was unwilling to be accommodating, and later he specially opened classes for these children of powerful people who went through the back door, but each of them had to charge two or three thousand taels of silver. Eventually, the money was used to build roads and schools in nearby villages. Xiao Yuanmao was impeached by many people because he opened the door to collect money, after all, publicly collecting money was contaminated with copper and insulting Sven.

Xiao Yuanmao responded with a ledger. The emperor still had a heart to defend this teacher who had smoked him, so he asked Master Li, who was most excited about the impeachment and shouted the loudest, to read the account book.

At that time, the civil and military officials stood for an hour and listened to Master Li read this account book.

Why does it take that long?

Because Xiao Yuanmao had already expected what would happen, he wrote down all the expenses clearly.

On September 21, the fifteenth year of Xiyuan, Jiangjia Village built a school for forty-five taels and four dollars.

On September 30, the 15th year of Xiyuan, there was a landslide at the south gate of Mingde Academy, and the villagers of the Jiang family were invited to come over to repair the road and afforestation, spending 324129 yuan.

On October 15, the fifteenth year of Xiyuan, Jiangjia Village built a school of thirty-five taels.

In the sixteenth year of Xiyuan, on November 11, the Ganzhou Charity Hall was rebuilt, and the fee was one hundred and twenty-one two hundred and sixty yuan.

……

……

In front of the ledger is where the money is used, and behind the ledger is the voucher.

Behind the ledger are the red handprints of the villagers and the signatures of the village chief.

The charity hall is the seal of the Ganzhou Prefecture. Everything related to the government has the seal of the local official.

The worst thing is that the last page of the ledger records which powerful children spent money to enter. It's just that these pages were not read out by Lord Li, and the emperor accepted it when he saw it, and it didn't make the owners of Youzhou hate Xiao Yuanmao.

The first emperor said at the time: "Xiao Yuanmao received 120,000 taels of silver a year, if you want him to be able to study in a positive style, why don't you give him 120,000 taels of silver every year!" After all, Youzhou is poor! ”

As soon as these words came out, the court was quiet.

The first emperor came again: "A total of twenty Qing families impeached Xiao Yuanmao, or each of you will send 6,000 taels of silver every year?" ”

As soon as these words came out, the faces of the twenty officials were so embarrassed! In the end, it was Master Li who was thick-skinned and was the first to kneel down and admit his mistake. That's it.

With the support of the emperor, Xiao Yuanmao's move made him famous.

Therefore, Lu Yingfang feels that Xiao Yuanmao is dedicated to students and the people, and such a person can become a partner.

However, Lan Ronghe's face was embarrassed: "Mother, how are you going to talk to Xiao Yuanmao?" "He is a military general, not to mention that everyone is staring at the Lan family at this time, if everyone knows that Xiao Yuanmao rejects the Lan family, the Lan family will only be more difficult! originally lost his title, but he lost his heart and face......
