"Most things in this world are not easy to come by. The words of saints and classics are used to discipline the world and have no practical use."
The emperor's words sounded reasonable. Zhang Yang sighed: "Yes, there are always many things in this world that are difficult at the beginning. How can there be so many things that come naturally?"
Zhang Yang poured the tea and continued: "Nanzhao has found a copper mine."
Li Shimin took the tea bowl and asked, "When did it happen?"
"The news was sent half a month ago." Zhang Yang put his weight on the back of the chair, shook the fan in his hand, and whispered: "I met a person who rented a carriage in Chang'an City. It seems that he was tricked by a powerful family and his family property was taken away from him, and he later went to Luoyang."
"After making a lot of money again, he came to repay his kindness. I asked him to go to Nanzhao and help me transport copper mines."
Li Shimin nodded and said, "You want to mint money?"
Zhang Yang shook his head, "Lishan doesn't cast money, nor does it bother to cast money. The casting process is inseparable from copper, and a lot will be needed in the future."
"What happened in Nanzhao really made you rich."
At this point, Zhang Yang didn't want to say more.
This is Lishan's family property. As an emperor, it is not good for the emperor to inquire about other people's family property. Besides, Lishan is surrounded by Longwu Army, so all the accounts are clear, so you can rest assured.
Zhang Yang took out a wooden box and opened it to reveal a row of lenses. "Your Majesty, try it and choose the most suitable one."
Li Shimin frowned and said, "Liu Li?"
"Yeah, it was burned."
"You do have a secret recipe."
Li Shimin took a piece of glass and observed it carefully. He was speechless and said, "This is the first time in my life that I have seen such transparent glass. If there was only one piece like this in the world, it would be worth ten thousand gold."
"I can give your Majesty two slices."
"Two slices?"
Zhang Yang sighed: "It's very difficult to bake. Let's not talk about this. Your Majesty will test your eyesight first."
There are many new things on Lishan Mountain. This is the first time Tian Khan has experienced the vision test.
Zhang Yang reminded: "Your Majesty, you must seek truth from facts. If you can't see clearly, you can't see clearly."
Li Shimin said seriously: "You just point it out."
Identifying the direction from top to bottom, Zhang Yang went back up and tried several times, but lost the wooden stick in his hand and gave up the test.
"What? Can't test well?"
"If you can't see clearly, you can't see clearly. Your Majesty, don't point blindly."
"Are you saying that my eyes are bad?"
Zhang Yang held his forehead and said, "This is not to show off, this is to see a doctor. Please be honest, Your Majesty."
Li Shimin clicked his tongue and said, "If you can't see clearly, I will shake my head."
After re-testing several times, Zhang Yang was sure of the emperor's vision, which was probably between 4.6 and 4.5.
Picking out a lens from the box, the emperor tried it several times before choosing two thinner ones.
Ancient people also had myopia, but myopia was not too harmful.
Tian Khan felt much better after wearing his glasses, especially since he no longer had to stretch his neck or squint when reading the memorial.
Li Shimin snorted coldly: "I thought it was some magic medicine that could restore my eyes to their original state, but I didn't expect to wear such an object on my face."
"This is all wisdom." Zhang Yang said as he put away the wooden box.
"Are you going to keep all these lenses?"
"Um."
Zhang Yang lifted the wooden box and saw that His Majesty was still looking at it as if he was greedy. Zhang Yang asked Xiao Wu who was beside him to take it back to the study until the box containing the lenses disappeared from sight.
This thing is valuable, very, very valuable.
Li Shimin even felt that the pair of glasses on the bridge of his nose was worth tens of thousands of dollars. Such transparent glass was rare in the world, and maybe only found in Lishan.
Zhang Yang has a secret recipe in his hand that can be used to make colored glaze. In a certain sense, as long as the colored glaze Lishan wants to have, he can have as much money as he wants.
"Your Majesty's short-sightedness has become very serious. I don't know how you read memorials before. You can't read clearly. You are easily agitated when you are physically and mentally exhausted, which is not good for your recovery."
Zhang Yang waved his fan calmly, "I will give this pair to Your Majesty, but the workmanship is poor and it is a little yellowed."
Li Shimin picked up the booklet on the side and looked at it. This was Lishan's account. There was no need to look closer or squint. He smiled and said: "How many years have it been since I ascended the throne? I don't know when to start reading memorials and I will be very tired. I have This thing is clearly visible at a glance, I feel ashamed, but..."
"There are many people in the court who need this thing, including the Prime Minister, Duke Zheng, and others. I am willing to pay 100,000 yuan to buy them all."
"It's not about money."
"You won't."
"It's not that I don't want to, it's just that Lishan doesn't want cash. If your Majesty wants it, you can give me some conditions in exchange."
"What conditions does Lishan want?"
"The prime minister and Zheng announced that I can come to Lishan to stay temporarily for a while when I return home."
"I promise you, even if I don't tell them, they still want to come to Lishan to visit."
The conversation ended peacefully. In the small palace, His Majesty took out his glasses, which made the maids and eunuchs beside him curious for a long time.
On the wooden frame are two pieces of transparent glass.
Li Shimin liked this feeling of clarity very much. He even read a few more memorials at night, and his anxiety was relieved a lot.
Even if the establishment of official schools is still blocked, I am not angry anymore.
Because he could see the words clearly, Li Shimin seemed to feel young again.
"Your Majesty, did Lishan bring this?"
"Well, it turns out that there is no magical medicine in this world that can make eyes look brand new. You can just use external objects to make the things in front of you clearer."
Queen Changsun thought of something and sneered, "There is another thing in Lishan Mountain called a magnifying glass. Zhang Yang wants to cultivate crops. With the help of the magnifying glass, he can see clearly the small changes in a wheat plant. I heard from Zhinu that he also plans to Build a telescope and it is said that you can see clearly the arrangements of soldiers and horses thousands of miles away."
"The child slave said that it is called clairvoyance, and also said that if it can be made better, you can see what the stars in the sky look like, and you can see clearly what is happening on the moon."
"If such objects really exist in the world, can we also see immortals?"
Empress Changsun shook her head and corrected: "Lishan is a mountain sect that values truth and knowledge. They believe that seeing is believing and are good at providing evidence for verification."
Li Shimin closed the memorial, nodded and said, "Mr. Guanyin, do you also feel that I have been eager for quick success in government affairs recently?"
"I feel that Your Majesty has not been out and about for a long time since the autumn hunting was banned last autumn. He wanted to see the scenery in the pass, stop for a walk, and have a good meal."
Inexplicably and a little sad, Li Shimin felt that he had neglected many things.
The queen will not participate in political affairs. All she can do is maintain the harem and run the clan.
She would not stand in the way. Li Shimin took off his glasses and read the memorial again, returning to his previous confused state, "Well, I'm not what I used to be."
There is a sense of helplessness in compromising with reality. The eyes will never regain their former brightness, and they will eventually have to rely on external objects. (End of chapter)
