Li Shimin

"I happen to have something, Qingque will definitely like it!"

After finishing speaking, he turned and walked into the house.

Soon, he came out with a small object in his hand.

After Li Shimin, Li Tai and others looked at the object, they couldn't help but be puzzled.

What's the use of just a handle made of purple sandalwood, with a ring of sandalwood on the front and a round piece of glass wrapped inside?

However, they didn't realize that Li Chengqian, Li Baoding and others had weird expressions on their faces.

"Qingque, this object is called a magnifying glass. It was carefully crafted by ink masters. Putting this lens on the text can magnify the text!" Li Xuan said.

"Enlarge text?"

Both Li Shimin and Empress Changsun were full of surprise.

And this time, Li Xuan had already handed the magnifying glass to Li Tai.

And from under the coffee table, he took out a small book, flipped through it, and signaled Li Tai to put the magnifying glass on those words.

"what?"

Li Tai was shocked all of a sudden.

Sure enough, he saw that the words on the small booklet had really grown in size.

Hastily removed the magnifying glass, and the text on the booklet returned to its original state.

Can't help but look shocked.

"Xuan Ba, how did you do this?"

On the side, Li Shimin and Empress Changsun were also shocked.

"This matter is just using the characteristics of glass, just like clairvoyance!"

Li Xuan chuckled lightly, but did not explain carefully.

Although this kind of thing seems simple, if he wants to explain it clearly to Li Shimin, then he may not be able to explain it clearly for a day.

"Thank you, Uncle Wang!"

Li Tai saluted and thanked Li Xuan with a happy face.

"Qingque, this magnifying glass can not only magnify the text, but also magnify the heat of the sun, so don't use the magnifying glass to look at the sun!"

This time, Li Xuan looked solemn.

"Uncle Wang, can a magnifying glass enlarge the sun?"

Li Tai looked puzzled.

Hearing this, a trace of helplessness flashed in Li Xuan's eyes.

"Take the magnifying glass and come out with me!"

Then, he took out a piece of paper from under the table and walked outside the house.

"Yes, Uncle Wang!"

Li Tai held the magnifying glass with a happy face, and followed Li Xuan out.

Behind him, Li Shimin, Empress Changsun and others also followed out with curiosity on their faces.

Li Xuan found a place with more sunlight, and put the paper in his hand on the ground.

Then, let Li Tai walk over, put the magnifying glass in his hand on the paper, and constantly adjust the position.

"Xuanba, what are you doing?"

Li Shimin asked curiously.

"Your Majesty, don't be impatient, you will know in a while!"

Li Xuan still stared at Li Tai closely, without turning his head.

Seeing this, Li Shimin smiled helplessly, looked at Li Tai, and didn't say much.

"Ok?"

Suddenly, a white smoke rose from the paper.

Before Li Shimin could ask in surprise, the piece of paper burned out of thin air.

"Uncle Wang, the paper is on fire!"

On the ground, Li Tai jumped up directly, his face full of shock.

"Don't worry, you lit it yourself!"

Li Xuandao.

"what?"

Li Tai was full of surprise, and quickly explained: "Uncle Wang, I didn't use flint to ignite the paper!"

"It's a magnifying glass. It concentrates the temperature of the sun, magnifies it many times, and slowly ignites this piece of paper!"

Li Xuan explained.

This time, Li Tai understood, stared wide-eyed, glanced at the magnifying glass in his hand for a while, and then at the paper on the ground.

This is the first time he has used a fire since he was a child, and the depths of his eyes are full of excitement.

"Therefore, when you hold a magnifying glass, you must never look at the sun, or you will burn your eyes. And don't hold the magnifying glass around in the sun all the time, it will ignite things!"

Li Xuan exhorted again.

Earlier, those bastards Cheng Chusi and Li Chengqian almost burned his small courtyard down!

"Please put it down, Uncle Wang, Qingque will definitely not look at the sun with a magnifying glass!"

Li Tai said solemnly.

"That's good!"

Li Xuan nodded lightly, he has already said what he should say, as to whether this little fat man will point the palace with a magnifying glass, it has nothing to do with him.

"Xuan Ba, can you give me more of such a fetish?"

On the side, Li Shimin also came back to his senses, looking at the magnifying glass in Li Tai's hand with an inexplicable expression.

"Xiao Xiang, Master Kong, and a group of great scholars read books all the year round, so that now, whenever the text is too small, they need to put their eyes on the books to read clearly. Therefore, I would like to reward some magnifying glasses, For these veterans, let them not have to work so hard to read books!"

"You can!"

Li Xuan chuckled, and continued: "However, every time I read a book, I need to hold a magnifying glass in one hand. It's too inconvenient, so I can ask the ink cure to make some glasses and put them directly on the eyes. Whether you are reading a book or walking, you only need to wear glasses!"

"Glasses?"

Li Shimin was puzzled again.

"Your Majesty, glasses are made of two pieces of this glass, which can be worn directly in front of your eyes!"

Li Xuan briefly introduced.

Hearing this, Li Shimin was very interested.

"So, please trouble Xuanba!"

"No problem!"

Li Xuan chuckled and said, "However, for this kind of glasses, those few people need to come to Lijiazhuang in person, and the black ink practitioners will personally adjust the thickness of the glass according to the conditions of their eyes, so that they can make suitable glasses! "

"Xuanba don't worry, after I go back, I will inform those few!"

Li Shimin said.

"Your Majesty, there is a fee for these glasses, and a pair of glasses is the same!" Li Xuan said.

"TOLL?"

Li Shimin was startled, with a strange expression on his face, those few were important ministers in the court, great Confucians in the world.

"nature!"

Li Xuanli was straightforward, "It took so much effort to make glasses for them, if there is no charge, wouldn't it be a waste of effort for some ink cures?"

"Xuanba's words are justified!"

Hearing this, Li Shimin didn't know how to refute.

"I will tell those people about this matter!"

"Ok!"

Li Xuan nodded slightly.

Afterwards, Li Shimin, Empress Changsun and others left happily.

As for the magnifying glass, Li Xuan didn't give Li Shimin much.

Although these magnifying glasses, he still has some at home.

However, the magnifying glass was just given to that fat little Li Tai as a gift, so you can't turn around and just take out a dozen more.

Li Xuan thought he couldn't do this kind of thing!

At least a few days.

Moreover, you have to pay!

"Master, can you also make glasses for Master Li?"

After Li Shimin left, Li Chengqian suddenly said to Li Xuan.

"You can!"

Li Xuandao.

"Thank you, Master!"

Li Chengqian's face was full of joy.

Although Master Li is usually annoying, but he is sincere to him!

……

Chapter 268 This king of Jin is indeed a virtuous king!

After returning to the palace, Li Shimin hurriedly called Fang Xuanling, Changsun Wuji, Du Ruhui, Xiao Yu and other important officials to Liangyi Hall, and explained in detail the method of salt sales department and salt banknotes.

"Your Majesty, I suggest setting up a capital salt department to sell salt with salt banknotes. This method can save a lot of salt labor, and at least tens of thousands of deaths and injuries of salt labor and cattle and donkeys can be reduced every year. It is good for the country, the people and the business. , all have great benefits!"

Fang Xuanling said with a smile on his face, the salt money, in his opinion, is simply like a magic pen.

"However, in this way, those aristocratic families and merchants can raise the price of salt at will after they get the salt. It only takes two aristocratic families to join forces. Even if there is a capital salt department to regulate it, the salt price will still be quite high!"

Wei Zheng was a little worried.

Suddenly, Changsun Wuji laughed lightly, and said slowly: "Everyone, there is a plan. All the families have money in custody in the Road Construction Department. In this way, after the family sells all the salt ponds to the court at a discounted price , the imperial court needs to distribute hundreds of thousands of money to those families at least every year!"

"Why don't I just set a rule for those aristocratic families, under the condition of ensuring that those aristocratic families and salt merchants can make money, they are not allowed to increase the price of salt indiscriminately, or deduct a certain amount of money as a punishment.

Moreover, from now on, the salt capital is not allowed to sell salt to that family! "

Hearing this, Li Shimin, Du Ruhui and others all looked shocked.

"Duke Qi's plan is very clever!"

"Your Majesty, I believe that the law that Qi Guogong said is feasible!"

Immediately, all the important officials agreed again and again.

"So, the matter of the salt will be decided accordingly." Li Shimin also nodded with satisfaction.

The matter of salt is certain, and more than half of the huge stone that was placed on Li Shimin's heart has gone.

Afterwards, Li Shimin began to talk about glasses.

However, when he thought that Li Xuan wanted to collect money, Li Shimin felt awkward.

However, I have to say it again.

His expression changed for a moment, and then Li Shimin coughed lightly, and said slowly: "My dear friends, I found something in Jinwang's other courtyard today, which is very useful for your reading!"
