Jing Yi received a share of 20,000 taels of silver from the restaurant sent by Xiao Zhen, which was a two-month share, Jing Yi was secretly surprised, this restaurant is too profitable. At this rate, you can get 120,000 taels of silver a year.

She and Xiao Yilin are divided fifty-fifty, so it means that the restaurant can earn 240,000 taels of silver a year, which is really a lot. If you open such a restaurant in the capital, it is estimated that it will be more profitable.

And that's just the restaurant. In the future, the sales of soy sauce will take into account the purchasing power of ordinary people, although the price is not high, but it is widespread. That's for the people of the whole country.

As long as you know the benefits of soy sauce, it is estimated that everyone will buy it. It adds up to a lot, and it really doesn't necessarily make less than the restaurant.

Jing Yi felt that this money could be divided into some points, which could be specially allocated for the military expenditure of the Jin State, and the troops of the whole country could benefit.

At that time, even if someone is jealous, Xiao Yilin's income will also have some scruples.

The restaurant and soy sauce workshop are managed by people from Jingwangfu, Jing Yi doesn't have to worry about it, she is now busy managing her own fields, busy researching cotton machines, spinning machines and looms.

Jingyi investigated and found that the textile technology of this era was very backward.

The current flower machine is the equipment for playing cotton, using very simple wooden tools, which is not only inefficient but also has a huge amount of labor for the flower maker.

The equipment used now to play cotton can play seven or eight catties of lint if one person is tired and tired, and he can play seven or eight catties of lint in a day. This efficiency couldn't be lower.

Jingyi is ready to design a more efficient springing machine.

She didn't just have to design the bouncy machine, she also had to improve the spinning machine and the loom.

In this era, there were materials such as kudzu, hemp, silk, and cotton, and these materials had to go through a very complex process from harvesting to threading and then weaving into cloth.

When Jing Yi was on a mission in his previous life, he had spent a long time in a remote area, where he had seen the weaving process of old coarse cloth.

The weaving process is extremely complex, from picking cotton spinning threads to weaving on the machine by ginning, elastic flowers, spinning threads, threading, pulping and dyeing, threads, falling threads, warp threads, brushing threads, making healds, breaking through, digging healds, hoisting machines, plugs, weaving, machines and other large and small 72 processes, all of which adopt pure manual technology.

There are many sub-processes in each process, and it is amazing to imagine how much work is involved in a product.

There are many families in Yunxi Village who have looms and can weave some coarse cloth. Some villagers can't afford to buy cloth, so they weave their own coarse cloth to wear.

It's just that the loom takes a long time to weave a piece of cloth, and the efficiency is really low.

It is no wonder that the price of this ancient cloth is not low, and many families cannot afford cotton cloth. Not to mention silk and satin, which can only be worn by rich people and dignitaries.

Jing Yi saw many people wearing very rough linen clothes in Yunxi Village, which was very uncomfortable to wear, not to mention, and did not keep warm when it was cold.

Jing Yi thought maybe she could increase the yield of cotton and bring the price of cotton down. Then design more efficient elastic machines, spinning machines and looms. Let the price of fabric also slowly drop in the future, so that people can wear cotton clothes. You can wear cotton clothes in winter.

In this way, she can both earn money and benefit humanity.

Anyway, she can't just make money or just think about revenge when she comes here, at least revenge is not realistic now. She can also do something meaningful. Otherwise, it would be a waste of her wood-based abilities and the thousands of years of culture she inherited.

Jing Yi got himself a studio in the wing room of the new courtyard, and he could do some research in it in the future.

Jingyi bought spinning wheels, looms and other equipment used for spinning and weaving, and then got them all in the studio. She drew a picture of what the devices looked like, then dismantled them one by one, numbered them, and fully understood their construction and principles.

Then Jingyi began to combine the knowledge in his head to transform these devices.

Jing Yi was able to become an ace agent in her previous life, not only because she was good at medicine and knew how to heal, but also because she had a genius brain.

She learns a wide range of things. There are a lot of things to learn because of her profession. She had to be able to use all kinds of weapons, all kinds of vehicles, and a lot of them. This requires her to be proficient in mechanics, weapons, etc.

Sometimes in order to get close to the target person, you need to learn other knowledge that is useful for the task, so it is not an exaggeration to say that Jingyi is knowledgeable in this ancient world.

Even now it's a piece of cake to let Jingyi design some thermal weapons.

It's just that in this era of cold weapons, Jingyi doesn't want to bring too lethal hot weapons to this world in advance.

Jing Yi first bought lead powder, made a simple pencil for herself, and then began to draw drawings one by one, and she also did a lot of calculations.

Lin Xiuhan has been coming to Yunxi Village often recently, and has become a frequent visitor to Jingyi's house.

But now that everyone is familiar with it, Qiao Hong and the others are not as restrained as before when they see Lin Xiuhan. The Liu family and Lin Xiuhan are also more familiar. She also admired Lin Xiuhan even more.

When Lin Xiuhan arrived at Chu's house, he was taken to Jingyi's studio by Qiao Hong, and was very curious to see some bookshelves and long tables in the room, some books were placed on the shelves, and various wooden components were placed on the long table.

He knew that his brother had bought a spinning machine and a loom, and now when he saw it, he knew that he had dismantled them.

Lin Xiuhan picked up a part and looked at it and said, "Jingyan, why did you dismantle them all?" What are you? ”

Jing Yi said: "I dismantled them to understand their internal structure and principle. Today's elastic machines, spinning machines, and looms are too inefficient. I want to improve it and increase their yield. ”

Lin Xiuhan's eyes lit up when he heard this, "Jingyan, are you sure?" ”

Jing Yi said: "It shouldn't be very difficult. I've now figured out how they are constructed and how they work. The next step was to draw some drawings and then have the village carpenter try them out. Take your time. Just improve the success before my cotton is harvested. ”

Lin Xiuhan saw a lot of symbols written on a piece of paper on the table that he didn't recognize, and asked curiously, "Jingyan, what kind of symbol is this, why have I never seen it?" ”

Jing Yi saw that it was a piece of paper she used for calculations, and it was full of calculated numbers.

"Oh, that's a common script in some other countries, and it's very convenient for counting, and I use it to calculate some data. This kind of writing has not yet been introduced to our country, so you should not have seen it yet. ”

Lin Xiuhan's eyes flashed with a strange light when he heard this, "Jingyan, do you still know foreign words?" To say that you are knowledgeable is not an exaggeration. Jing Yan, can you teach me this kind of writing? ”

Jing Yi said: "This kind of writing is generally used for counting or arithmetic. It's what you usually call arithmetic, and I think it's very convenient to use this kind of text to calculate. If Brother Lin wants to learn, I can teach you. ”
