I am engaged in construction in Datang

"Master Li, can you sell us this curved plow? I want to show it to Alang." (In the Tang Dynasty, the master was called Alang or Langjun, which sounded awkward. Later, it was changed to master, master and adults)

"Manager Liu, just take it away. Zhuangzi will pass on the blueprints and the method of selecting seeds with salt water in the future. This is just a pile of wood and is worthless."

"Um... the blueprints for the curved plow and the method of selecting seeds with salt water, can you give me a copy first?"

Liu Quanshu hesitated and coughed, "We still want the new abacus we used for calculations, and the method of using it..."

"It's a small matter. I'll have someone prepare it."

As it was getting dark, Li Yin invited everyone to have dinner.

When leaving, Liu Quanshu carried a lot of bags with him.

In addition to the curved plow, abacus, and the method of selecting seeds with salt water, there were also two pounds of Jingguo noodles, two pounds of shaqima, and a large bag of egg rolls made on the farm, as well as the newly launched snack dragon beard cake, a roasted rabbit, and a jar of pickled radish. The pickled radish made on the farm tasted different from those elsewhere, and was crispy and refreshing, and went well with rice.

Owner Li said that the manor made money quickly, so he stuffed a lot of money into the account.

In the evening, Li Yin and Xiaochun began to check the accounts in the village. Feng Sanxi reported on the progress of various matters in the village and also sorted out the situation of the cooperative merchants.

"Now Liuweizhai's daily profit is about ten strings of cash, not counting bulk purchases." Li Xiaochun said, "Should we start selling sugar?"

"It's not time yet." Li Yin shook her head. There are risks. "Tomorrow we will go to the slums and find some needy families. I have some snacks. We will provide them with utensils and let them sell them. After they make money, we will collect rent."

"There are also toys like the Rubik's Cube, Tangram, Luban Lock, and building blocks, which are easy to make and can be placed in Liuweizhai."

Li Xiaochun wrote them down one by one.

These little gadgets are just extras, designed to attract people, and they don't make much money.

Li Yin planned to make it more exquisite, engrave the logo of the women's farm on it, and sell it specifically to aristocratic families. She also did not intend to stop the common people from imitating it. Those who were interested could make some in their free time and sell them to supplement their family income.

"Is the soap made?" Li Yin continued to ask. She had given the recipe before.

"It's made, but the scent types of the soap need to be improved." Feng Sanxi wrote quickly, fearing that he could not keep up with Li Yin's train of thought.

"Don't worry, just make it. Let's use the soap and perfumed soap ourselves first, and then wash our hands with perfumed soap before meals and after going to the toilet."

The soap smells a bit fishy, ​​but it is very clean when washing your face or clothes, and it is also easy to make. It should be placed in Liuweizhai now, but it is a strategic material and cannot be sold. I will sell it later when I am short of money, and I will not sell more.

Feng Sanxi's charcoal pencil broke, so he held the remaining piece and continued writing quickly.

Li Yin: “…”

Oops, I almost forgot something important.

"Have you found the clay I mentioned? And the graphite mine?" It will be used to make pencils. She gave the direction and distance. There are no plans to mass-produce it at the moment, so Zhuangzi will use it first.

"Yesterday, Xiao Yang sent someone back to say that they have made some progress." Feng Sanxi thought of Liu Quanshu who came today: "Master, that Liu Quanshu may be someone of great importance."

During the spring ploughing season, they were given a small farm to borrow some oxen for plowing, and they even came to ask about it specifically. The person behind this is no simple person.

"Isn't that great?"

Li Yin thought for a moment and said, "I hope it's big enough, so we don't have to worry about launching something new."

For example, for white sugar, she didn't want to sell it at a high price, she just wanted to slowly lower the price so that ordinary people could have white sugar to eat. Now there is cheap and abundant brown sugar on the market, but it tastes average and is not as versatile as white sugar.

Speaking of sugar, Li Yin thought of salt: "Uncle Sanxi, come on, give me paper and pen."

“…” Feng Sanxi has to go back and study it carefully tonight.

He hasn't slept early a night since the old owner passed away.

"This year, His Majesty... conquered Tuyuhun." Li Yin stopped talking in time and said, "There is a salt lake!"

Li Yin picked up a pen and wrote the title on the rice paper: Salt Lake Salt Washing and Purification Method.

Although Chang'an is not short of salt, there are many people in the world who are short of salt. Salt makes huge profits. If the Qinghai Salt Lake can be reasonably developed, the price of salt can be cheaper without affecting the interests of salt merchants.

The farm cannot do this business as it will easily attract attention. The farm will just provide a solution.

Li Yin always believed that the village did not need to hoard too much money. Only by letting the money circulate could it develop. Otherwise, if the village were like those wealthy families and buried their money, how could it develop?

There is a shortage of copper in the market now, and ordinary people can only use silk as money.

The sight of those pieces of cloth made her heart ache.

In recent days, soap has been widely used in the village. Everyone lines up at the sink to wash their hands before eating. The owner of the village teaches them the seven-step hand-washing method, and then they wipe their hands clean with the towel they carry with them.

The water for washing hands is not cold. The sink is next to the canteen. The villagers boil the water when they use biogas to cook.

"I don't know why, even though I have to do farm work every day, I always feel that my life is more comfortable and meaningful than before." A scholar washed his hands and chatted with his companions.

He had just finished teaching when he met Zheng Wen, who taught mathematics, at the sink.

"We are learning new knowledge all day long, and it is all for the benefit of the people. Zhuangzi is changing too fast, and we will be left behind if we are not careful. So our life must be meaningful." Zheng Wen wiped his hands with his towel.

"Now I know how to grow several crops, how to select seeds, what kind of soil to plant them in, when to harvest them, and how to intercrop them. The farm has bought a lot of ducks and hens. I feed them every day and I also know how to make them lay more eggs!"

"It's not just that." A student echoed: "Before we didn't have the conditions to learn horse riding, but now we can all ride horses and shoot arrows. Now that our physical fitness has improved, we can even kill the enemy."

"If we don't know the six arts of a gentleman, we won't be happy. But being happy depends on talent!"

After washing their hands, the group went to get the dishes and chopsticks as they walked.

The canteen attendant saw several students and greeted them, "Master Zheng, Master Yu, Master Duan, we have braised pork slices today, would you like a spoonful?"

"Then give me a spoonful."

Several people passed their bowls around and found a table to sit down after finishing their meal.

Zheng Wen took a bite of meat and sighed, "I don't want to leave on a day like this."

The student surnamed Yu disagreed: "You and I have worked so hard for so long, and now the environment and conditions are so good, we must pass the exam this time!"

"Brother Yu is right." Zheng Wen nodded. When he becomes an official in the future, he will protect Zhuangzi.

Zhuangzi is very powerful, but how can he succeed without someone to support him?

……

Daming Palace.

Li Shimin looked at the rice paper on the desk in silence.

"Wang De, what is density?"

Wang De: "..."

We only have a vague understanding of it!

"Your Majesty, let me give you an example. If fat and lean meat are of the same size, the lean meat is heavier, so it has a higher density." Wang De wiped his sweat. Fortunately, he had done his homework.

"Can salt water really select good seeds?" Li Shimin frowned. "What is plasmolysis? The concentration difference causes the water in the seeds to seep out, and the mass becomes lighter and floats on the water. This is an incomplete and inferior seed... I, I can understand every word, why don't I understand it when you put it together?"

"Wang De, what do you think?"
