Thank you for the reward of Thunder and all readers for your support.

Gao Jingming said with a smile: "Two generals, you come to find Your Highness too."

Hou Junji smiled and said, "Old Gao, I still have to thank you for the last time when the land auctioned in Xianyang. We made a little money from our brothers. Let us go back and invite you to drink."

Gao Jingming smiled and said, "You really have them. Before going out to fight, you knew that you had bought land with a coal mine. You had a vision. It was amazing."

Li Daozong smiled and said, "That's natural. We are not reckless men who only know how to fight. We can do things like making money. Haha."

Gao Jingming laughed and bowed to his goodbye.

In the study, Li You saw that it was getting late and said to Xi Magpie: "What should I eat tonight?"

The magpie said, "Prince, I suddenly discovered a problem. There are so many delicious foods, and nothing tastes good."

"Oh, Magpie, you are so talented! I said, why is your appetite getting worse and worse? It turns out that the problem lies here." Li You suddenly realized.

He thought about it for a while and said to the magpie: "You inform the kitchen to make millet porridge tonight, copy the pineapple with boiling water, remember not to overheat. Just cut some green onions, garlic, oysters, and some salt. Just eat this tonight."

Soon, Gao Jingming arrived.

"Sir Gao, you won't go to the Three Treasures Hall without any trouble. It must be a troublesome thing when you come." Li You said with a smile.

"Otherwise, your highness is so powerful that you will know your purpose before you can speak." Gao Jingming smiled.

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

Gao Jingming smiled and said, "Okay, I heard that Your Highness is the number one foodie in the Tang Dynasty. I am thinking of having a good time."

Li You said, "If you have something to talk about, let's have a meal here, and talk while eating." After that, he ordered, "Notify the kitchen and send the food here."

Gao Jingming said: "Your Highness, summer taxes have begun to be put into storage, and the Ministry of Revenue has been a little better. However, cash is very tight, which is really inconvenient."

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

The proportion is 78.14%, 7.21%, 12.29%, and the proportion of copper is the highest. Over the years, the copper content has gradually decreased. By the 10th year of Zhenguan, the 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 Tang Dynasty's copper is becoming increasingly lacking, which has seriously affected the development of the society and economy.

For the Ministry of Revenue, most of the taxes are grain and silk, while Kaiyuan Tongbao is only a small part, and some of the expenditures can also be made with silk and grain. However, there are more places where cash is needed.

Imagine the inconvenience of bartering, for example, if you want to have a meal in a restaurant and carry a few bags of white noodles, you will know how much the lack of circulating copper coins will have.

The core issue here is the word "copper".

After Gao Jingming finished speaking about his purpose, Li You nodded to show that he understood.

At this time, Wang Liao brought people to deliver food. Gao Jingming was shocked when he saw it - is a famous foodie just eating this?

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

Xi Magpie said her high statement, and Gao Jingming also thought it made sense, so he ate this simple meal with Li You, and it was indeed good.

He praised: "Sometimes, it is a good choice to simplify the complex and return to the essence."

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

After dinner, Li You said: "The Tang Dynasty did not lack copper mines. There were many mineral veins in Chang'an area. 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 and form a mining school. Let's open a copper mine together, study and build it. When the copper mine can form production capacity and operate normally, the students will be trained. Then recruit a group of students. According to this model, a large number of talents will be cultivated in the near future."

Gao Jingming nodded and praised: "Yes, it's a good idea. I will suggest it to Your Majesty."

Li You hurriedly said, "Don't mention me, I have a lot of things in my hands. Have I lost weight if I didn't see it?!"

Gao Jingming smiled and said, "It must be. If your Highness can come up with an idea, I am very satisfied. However, if you need your Highness's help, please give me some advice."

The two discussed the matter about the construction of copper mines for a while, and Gao Jingming raised another thing, and he said: "Your Highness, there is something happening right now, and I am very embarrassed. Not only is it because I am embarrassed, but even Your Majesty is in a difficult situation. Can you come up with an idea?"

Li You hurriedly said, "I have no idea. I am a teenager. The matter between you and you have solved it yourself."

He was a little scared. He just came up with an idea about asking for rain, but in the end he almost caught it. If it really didn't rain that day, would it be unimaginable what the consequences would be.

When Li You came to the Tang Dynasty, he was basically not idle. One thing that made him feel tired. Even if it was the copper mine in front of him, he might have been busy.

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

Gao Jingming saw that Li You mentioned this, so he stopped forcing him. He sat for a while, got up and said goodbye.

Li You turned down something and felt a little bit more balanced. Suddenly, he found that it was very difficult to talk too much and he was a little hungry. So he asked someone to serve another bowl of millet porridge and eat it.

Li You collected relevant knowledge about copper mine detection and mining, copied it for a while, and felt that this job was too tiring. He missed the days when he could copy and paste. Even if he typed, it was much easier than writing with a brush now.

When he thought about how to improve efficiency, he remembered the shorthand.

Yin Guanghao, the chief clerk of the research institute, is equivalent to the office director, so Li You began to let him take the lead in learning shorthand. He planned to read the information to these stenographers in the future and then let them organize it into documents, which would be much more efficient.

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

Li You and Yin Hongzhi had an agreement that there was no need to tell him about things in the court, and he was too lazy to think about it. However, if something was related to him, Yin Hongzhi would come to remind him.

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