Thank you for the reward and all the book readers for their support.

Gao Jingming said with a smile: "Two generals, you also came to find Your Highness." ”

Hou Junji said with a smile: "Old Gao, I still want to thank you for the last auction of Xianyang land, let our brothers make a little money, and invite you to drink when you go back." ”

Gao Jingming said with a smile: "It's really yours, before you go out to fight, you know that you have bought land with coal mines, you have vision, it's amazing." ”

Li Daozong said with a smile: "That's natural, we are not reckless men who can only fight, and we will also make a fortune." Ha ha. ”

Gao Jingming laughed and said goodbye.

In the study, Li You saw that it was not early, and said to the magpie, "What should I eat tonight?" ”

The magpie said: "Lord, the slave maid suddenly found a problem, there are too many delicious things, and nothing is fragrant to eat." ”

"Oh, magpie, you're so talented! I said, why is your appetite getting worse and worse, it turns out that the problem is here. Li You suddenly realized.

He pondered for a moment and said to the magpie: "You inform the kitchen to make millet porridge tonight, copy the pineapple vegetables with boiling water, and remember not to go overboard." Cut some green onions and garlic, oysters with some oil, and put some salt. Eat this tonight. ”

Soon, Gao Jingming came.

"Master Gao, you have nothing to do but ascend the Three Treasures Palace, it must be a troublesome matter." Li You said with a smile.

"If you don't say that Your Highness is powerful, the minister hasn't opened his mouth yet, and you will know the minister's intention." Gao Jingming said with a smile.

Li You said: "I'm a little hungry, why don't you eat with me?" ”

Gao Jingming said with a smile: "Okay, I heard that His Royal Highness is the first gourmand in the Tang Dynasty, and the minister is thinking about feasting on it." ”

Li You said: "You have something to discuss, let's eat here, talk while eating." After saying that, he commanded, "Inform the kitchen and bring the food here." ”

Gao Jingming said: "Your Highness, the summer tax has begun to enter the treasury, and the household department is a little better." However, cash is very tight, and it is really inconvenient. ”

The cash that Gao Jingming refers to is copper coins, that is, Kaiyuan Tongbao. Kaiyuan Tongbao began to be minted in July of the fourth year of Wude, and its main components are copper, tin, and lead.

Its proportions are 78.14%, 7.21%, and 12.29%, with copper having the highest proportion. Over the years, the copper content has gradually decreased, and by the 10th year of Zhenguan, its proportion has become 60.13%, 12.32%, and 26.45%.

If the copper content continues to decrease, the quality of Kaiyuan Tongbao will not be able to meet the needs of circulation.

This data shows that the increasing shortage of copper in Datang has seriously affected the social and economic development.

For the household department, most of the taxes are grain and silk, Kaiyuan Tongbao is only a small part, and part of the expenditure can also be carried out with silk and grain. However, there are more places where cash needs to be used.

Imagine the inconvenience of bartering, for example, going to a restaurant for a meal and carrying a few bags of white noodles, to see how much of a lack of copper coins for circulation can have an impact.

The core problem here is the word "copper".

Gao Jingming finished speaking, and Li You nodded to show that he understood.

At this time, Wang Liao brought someone to bring food, Gao Jingming was very surprised when he saw it-a famous foodie, does he eat this?

Seeing Gao Jingming's doubts, Li You smiled and said, "Lord Gao, there is a lot of knowledge here, magpie, you come and talk to Lord Gao." ”

The magpie told her about her high arguments, and Gao Jingming also felt that it made sense, so he ate this simple meal with Li You, which was indeed good.

"Sometimes it's a good idea to keep things simple and get back to basics," he says. ”

During the meal, Li You searched for materials related to copper mining.

After eating, Li You said: "Datang is not short of copper mines, there are many ore veins in Chang'an, and what is lacking now is talents.

The construction of copper mines requires a large number of talents from exploration, infrastructure, mining, smelting and transportation, and the cultivation of talents cannot be completed overnight. ”

Gao Jingming asked, "Is there any quick way?" ”

Li You said: "There is only one way, which is to recruit a group of students and craftsmen to form a mining school. Let's go to open a copper mine together, learn and build at the same time, and when the copper mine can form a production capacity and operate normally, this group of students will be trained. Then recruit a group of students, and according to this model, a large number of talents will be able to be cultivated in the near future. ”

Gao Jingming nodded and praised: "Yes, it's a good idea, the minister will suggest it to His Majesty." ”

Li You hurriedly said: "Don't mention me, I have a lot of things in my hands, don't you see that I have lost weight?!" ”

Gao Jingming smiled: "Definitely." His Royal Highness was able to come up with an idea, and the minister was very satisfied. However, if you need your Highness's help, please give me a lot of advice. ”

The two discussed the construction of the copper mine for a while, and Gao Jingming proposed another thing, he said: "Your Highness, there is something at the moment, and the minister is very embarrassed. Not only the ministers are embarrassed, but even His Majesty is also embarrassed, can you come up with an idea? ”

Li You hurriedly said: "I don't have an idea, I'm a teenager, and the matter between you adults will be solved by yourself." ”

He was a little scared, he just came up with an idea about asking for rain, and as a result, even he almost got in, if it really didn't rain that day, what the consequences would be, I really can't imagine.

When Li You came to the Tang Dynasty, he was basically not idle, one thing after another, which made him work hard, even the matter of the copper mine in front of him, he was afraid that he would have to be busy.

What Gao Jingming said can make Li Shimin feel embarrassed, it must not be a simple matter, and Li You is not willing to get involved.

Gao Jingming saw that Li You said this, and he was no longer reluctant. He sat for a while, then got up and took his leave.

Li You pushed away one thing, and his heart was somewhat balanced, and suddenly he found that it was very difficult to talk too much, and he was a little hungry. So I asked people to fill another bowl of millet porridge and eat it.

Li You collected the relevant knowledge about copper exploration and mining, copied it for a while, and felt that this work was too tiring, and he missed the days when he could copy and paste, even if it was typing, it was much easier than writing with a brush now.

As he pondered how to improve efficiency, he remembered shorthand.

Yin Guanghao, the main book of the research institute, is equivalent to the director of the office, so Li You began to let him take the lead in learning shorthand. In the future, he plans to read the information to these stenographers, and then let them organize it into a document, which will be much more efficient.

This morning, Li You was testing the learning effect of the stenographers, and Yin Hongji came. He had just come up from the morning court.

Li You and Yin Hongzhi have an agreement, and there is no need to tell him about things in the court, he is too lazy to use that brain. However, if it is related to him, Yin Hongji will come to remind him.

Yin Hongzhi told Li You about what happened in the court today.
