During this time, Li Yuanjing did not plan to continue to live in Chang'an, but Wang Xiaoyi was still left in Chang'an by him.

The two of them are still too young, and it is not good for them to be exposed to adult life too early.

Especially for women, even if they are not pregnant, there is still some impact on the development of the body.

Li Yuanjing can't control the entire Tang Dynasty in these things, but he can start from himself.

And in the next period of time, he has a lot of things to do.

Holding the results of Liu Hu's investigation in his hand, he was a little rough, but he was much more detailed than his own requirements.

For example, the Zheng family, or several major families, still have some things in common in terms of making money.

The first place in the list is grain, the family has grain stores in Chang'an, and all the states in the world are almost divided by several major families, and there are few cases of invasion of other markets.

As one of the largest landlords, the family's lending was not much kinder than that of the old village wealthy, and lending was their main means of carrying out land annexation, and its efficiency was high and the cost was low, far more than taking money directly to buy land.

Liu Hu even found a practical case, in the first year of Zhenguan, Sun Laohan of Tugou Village, a village in Qizhou Township, borrowed 50 acres of grain seeds when he was cultivating in the late autumn, and the two sides agreed to borrow money for a period of one year, and return 10 yuan at the end of the year.

Under normal circumstances, the yield per mu is about one stone, and according to the grain price at that time, one stone of grain can be sold for more than three times.

However, the purchase price was very low, and the landlords and gentry did not allow the people to sell grain privately, but had to sell it to a limited number of people.

That is to say, Sun Laohan needs to take out the output of ten acres of land to repay this money, but the heavens do not fulfill people's wishes, there was a major drought in the second year of Zhenguan, coupled with a small number of locust plagues, resulting in a sharp drop in grain production, and the output in the field Sun Laohan is not enough to eat, let alone repay the money.

In just three months, Sun Laohan's fifty acres of cultivated land became the land under the name of the Zheng family, and the fifty acres of grain were exchanged for fifty acres of land in one year, and such transactions abounded.

In the end, Liu Laohan's family was miserable and felt that life was hopeless and was forced to move to the border, but the family did not go to the border, but starved to death on the way, and was tragically wiped out.

The third is cloth, the most used on the market is raw silk, ordinary people use this one, the price has risen a lot with the disaster year, at present about 400 yuan a horse.

In addition to the three most profitable, the Zheng family also opened pawnshops, grocery stores and other stores, and almost all the ranks they could see.

Li Yuanjing frowned deeply, the truth was more difficult than he imagined.

Although it is quite easy to talk about it, for example, to increase grain production, in order to suppress grain prices, push the official warehouse to increase the purchase price, and allow the people to sell grain to the official warehouse, so as to reduce the amount of grain in the hands of the family to the greatest extent.

For example, to open a money bank to lend, only a small amount of interest, in order to squeeze the family's financial path by lending.

But none of these things were easy, and they didn't meet my initial goals.

Li Yuanjing set his sights on the cloth, the background of the family is not comparable to himself, the plate was too big at the beginning, and he could only die quickly enough.

Yang Li has been liberated from scientific research work, according to Li Yuanjing's instructions, Yang Li made a quyuan plow, and then the peaches were picked by Cheng Chuliang, and he only took a reward of 200 yuan.

Although my mother keeps selling batches in my heart, I still have to be happy on the surface.

"Are you familiar with looms?" Li Yuanjing walked to Yang Li's side, and Yang Li was taking a few apprentices to help Huangzhuang build a Quyuan plow.

Mainly because of Li Yuanjing's promise to him, for every apprentice he brought out of the school, he would be rewarded with fifty yuan of money, and the fifty apprentices would be brought out of the school, and each of the fifty apprentices would be an apprentice, and Li Yuanjing would find a way to make him knighted.

Faced with the temptation, the frightened Yang Li directly rejected the reward of fifty guan, and said that he would definitely bring fifty apprentices out as soon as possible.

"Familiar! I have built more than a dozen of them by myself, but I have repaired no less than 100 looms. Yang Li nodded hurriedly.

"Is there a loom in Zhuangzi?"

"Yes!"

Yang Li hurriedly took Li Yuanjing to the nearest Zhuang family, he had only helped them repair the loom a few days ago, and it was His Royal Highness who was there in person, and the family was happy to wait left and right.

Yang Li thought that Li Yuanjing wanted to understand the loom, so he personally went into battle to demonstrate.

The efficiency of the honest loom is very low, but in fact, this is still an improved loom, and the efficiency has been increased by more than ten times compared to the ancestor of the loom.

But the loom in front of him is somewhat similar to the loom in his memory, and after seeing this loom, Li Yuanjing also discovered a fact that since the birth of this loom, there has been no further improvement for thousands of years, and it can only be said that changes have been made in some small aspects.

After looking at it for a while, Li Yuanjing finally discovered the biggest difference.

"I think we can improve this thing and find a way to make it faster to go back and forth, so as to improve the efficiency of the loom." Li Yuanjing pointed to the shuttle and said.

Yang Li frowned, thinking carefully about Li Yuanjing's suggestion.

If you speed up the shuttle, you can indeed improve the efficiency of weaving, this problem is very simple, and there is no need to verify it.

Because the weaving is spent most of the time on the shuttle, followed by the control of the density, the shuttle occupies almost more than sixty percent of the time.

With the two cases of Quyuan plough and waterwheel in front of him, a seed of innovation has been planted in Yang Li's mind.

So subconsciously I also thought in this direction, but after thinking about it for a while, I still had no idea, but I found that I seemed to have neglected King Zhao, and hurriedly said: "Your Highness, this idea should be feasible, but it needs to be carefully considered and tested!" ”

"Well, during this time, you will take your apprentice to study this, and if you need manpower, come to this king!" Li Yuanjing nodded and ordered, as if to show his attention, and then added: "This matter is very important!" ”

How to play with the Maison? Of course, it is a price war, but I can't afford to lose, so I can only find a way to reduce the cost.

Improving production efficiency is a disguised way to reduce costs and expand scale, and it is also a way to reduce costs.

With these two measures in place to reduce costs, the Maison can only sell as much as it loses until it finds a real resistance strategy.

"Please rest assured, Your Highness, your subordinates will definitely study it as soon as possible!" Yang Li nodded again and again, if there is something to do, the greater the chance of meritorious service, even if he can't be knighted, he can get another reward, and when the time comes, he can buy a few tilts of land, even if he is not knighted, he will live a very comfortable life.

"Do it well, in a few years, this king will get you an official body to play ......"

"Your Highness, Duhe is here!" The three of them, Changsun Lian, Cheng Chuliang and Fang Yiai, leaned against the door, looking at Li Yuanjing with a smile, and there was this somewhat timid Du He behind him.

Li Yuanjing glanced at Changsun Jian and asked directly, "Where are your craftsmen?" ”
