I am engaged in construction in Datang

"Tomorrow I will ask Xiaosong to go to the city to recruit workers. Engineer Wang, you can come with him and pick out the people you like and bring them back."

After Li Yin finished speaking, she saw Wang Dahai's eager eyes and understood that he was thinking about his household registration.

"I have sent someone to Bianzhou, and you and Erya's household registration will be moved here in a few days."

No government office will refuse donations.

If one string of money isn’t enough, then try ten strings. Anyway, Zhuangzi always has a way to make money.

The bean curd sheets and Liuweizhai snacks had become popular throughout Chang'an, and many foreign merchants directly bought thousands of kilograms of bean curd sheets.

Nowadays, a pound of beans only costs five coins. According to the ratio of two pounds of soybeans to one pound of yuba, a pound of yuba can make a net profit of ten coins, and a thousand pounds of yuba can make ten strings of cash. (The New History of the Tang Dynasty records that rice and beans were very cheap during the Zhenguan period. A dou of rice (12.5 pounds) only cost five coins, but this does not conform to the logic of prices. The area around Chang'an is not suitable for growing rice, and it needs to be transported over long distances. Xi'an has convenient water transportation. The author reasonably speculates that the records are somewhat "beautified", so the prices are "slightly" increased.)

And those little snacks, the icing on them is white!

If the farm had not already found a way to make white sugar, Li Yin would not have dared to sell it that way.

A pound of white sugar now costs 80 wen on the market, and better ones can cost 150 wen. However, Liuweizhai’s snacks are only about ten wen a pound. They are so sweet, topped with sesame (introduced by the Western Regions Hu people, later called sesame) and dried fruits, and are fried.

Everyone in Chang'an City thinks that Liuweizhai is doing business at a loss!

Wang Dahai was relieved. Before leaving, Li Yin asked Erya to go to school the next day. The classes taught in the morning by Zhuangzi were for children under the age of 16. Children were not fully grown and could not do heavy work all the time.

After the students arrived, Li Yin sought their opinions and started classes in the evening to teach the adults in the village with the aim of promoting literacy.

There are more and more things to do on the farm, and these tenants certainly cannot keep doing meaningless mechanical labor. They will have to take care of many things in the future. How can they cope without being able to read and count?

Yeah, we have to get out the abacus.

The abacus used by accountants today is not as comfortable as that used in later generations.

Busy!

Li Yin returned to the bedroom, turned on the biogas lamp, and drew the abacus diagram.

Afterwards, she wrote a medical book and planned to start teaching medicine to the children in the village.

Fortunately, there is a system that allows her to exchange contribution points for various blueprint knowledge, and most importantly, it is cheap. She has never worried about insufficient contribution points, but only about insufficient productivity.

Otherwise, she really couldn't carry so many things...

"System, you are so nice." Li Yin sighed happily before going to bed.

【…】

……

Liu Quanshu was very happy to receive the reward, and was thinking about when he would visit the girl's farm again. His godfather asked him to take good care of her.

Now that spring ploughing is approaching, I wonder if there are enough large livestock over there.

With something on his mind, he took immediate action, prepared the carriage, and drove towards the women's farm.

Today Li Yin led the tenants in selecting seeds. The simplest method is to soak them in salt water for 12 hours. Those that are not full or cannot adapt to the environment will not be planted and will be left to be eaten.

When Liu Quanshu arrived, everyone had just started adding salt water.

Feng Sanxi received them and led them to find Li Yin.

"Manager Liu." Li Yin bowed.

"Master Li." Liu Quanshu returned the greeting and then asked in confusion: "What are you doing?"

"This is salt water seed selection. By using the density of water and the alkaline environment, we can select good seeds that are full of vitality and full inside. It can also kill bacteria, so that the germination rate will be high in the future."

Li Yin held the salt basin and scale, while Wang Erya held an abacus, ready to calculate the amount.

"First calculate the amount of salt required for 5L of 50% salt water. The density of salt is about 2.165 grams per cubic centimeter."

Schools now teach various units of measurement. At the beginning of the Tang Dynasty, 1 jin was approximately 600 grams. People in the village used 500 grams to measure things for easy conversion, and they could use 600 grams when they went out.

She gave Wang Erya her textbooks individually.

Over there, Wang Erya was clacking away on the abacus. Actually, she could just do mental arithmetic, as using the abacus could help her verify mistakes.

"Five percent times 50 liters equals about 2500 milliliters... I figured it out, so I need a little more than 10.8 kilograms of salt."

Liu Quanshu was completely confused.

He wanted to take out a pen and paper to make a note. This would be useful!

But why couldn't he start?

And the thing the girl was holding was crackling and it stopped all of a sudden, it was scary.

Li Yin weighed the salt and poured it into a 50L tank. Others poured water into it, stirred it, and finally put a 5% label on it.

There are four water tanks next to it, filled with 8%, 11%, 14% and 17% salt water respectively. After the autumn harvest, we will see which concentration produces the best seeds.

When I was done, lunch was ready.

Li Yin invited Liu Quanshu to the cafeteria for dinner.

I had noodles for lunch today. I added salt and oil to the noodles when making them, then rolled them back and forth with a rolling pin, and finally cut them into noodles as thick as chopsticks. I boiled them in water, then rinsed them with cold water three times, and finally took them out and rinsed them with cold water again.

The rabbit stew is made with beef bones.

There were coriander, shredded cucumber, shredded green onion, pickled radish cubes and pickled garlic cloves on the side as side dishes.

If you want to eat dry mixed, don’t add soup, just add the meat sauce.

If you don’t want to eat noodles, there are kangbing, which is just as delicious with some braised meat and beef bone soup.

Liu Quanshu ate with relish. Nuzhuang really had a way with food.

"Master Li, my son Alang asked me to ask if the farm is short of large livestock." Liu Quanshu stated his purpose.

"Need it!" She had originally planned to rent a house from another village, but it was spring time and it was difficult to rent a house even if she paid more money, so she was worried.

Last year, all the land in the village was rented out for short periods of time. This year, she decided not to rent any land out as she wanted to plant all the land, but she did not have enough manpower or oxen.

After the autumn harvest this year, the farmers will buy more large livestock, as it is difficult to buy them at other times.

"The manor doesn't take advantage, it pays for rent." Li Yin interrupted Liu Quanshu and said, "Manager Liu, the manor has money, but too much money is useless. It can only be circulated after it is spent."

"Good things can be found in the village, so there is no need to buy them elsewhere. Hoarding so much money is actually of no use. Instead, spend it and let the people have money in their hands, so that they can buy things in the village, and then the village can use the money to develop. This is called currency circulation, a virtuous cycle."

“……”Liu Quanshu didn’t understand again.

But I have already taken out the pen and paper to write it down.

In the afternoon, Li Yin was going to experiment with the efficiency of the curved plow, and Liu Quanshu followed her.

The oxen in the village had been tied to the curved plow. Only five finished products had been made in total. Li Yin checked the small parts of the curved plow and found no problems.

Li Yingwu started to herd the cattle.

Wang Dahai took a piece of paper and a charcoal pencil and scribbled down the areas that needed improvement.

Almost all the people in the village who had no work came here. They were all working in the fields. How could they not be happy to see that the efficiency of farming had increased?

The students also came. They followed the children to plow the fields this afternoon. They had no idea what it was like to plow the fields for many years before, but after coming to Nuzhuang, they saw it thoroughly.

Master Li said, how can you be an official if you don’t know how to do farm work?

If people ask you when is the best time to plant beans, can you shake your head and say you don’t know?

They were also happy to see that the newly plowed fields were so efficient!

Liu Quanshu also knows how to farm. He had a hard life before entering the palace. After entering the palace, His Majesty loved to farm, and his master also wanted to farm, so naturally he knew how to do it.

The thing called the curved plow that we see now is so efficient, so scary that his hands are shaking even when he holds the pen!

Oh, he is going to the palace tomorrow!

He has to find a godfather!
