Li Shimin

Li Xuan looked at Li Shimin strangely, and slowly said: "As the prince saw, using glass as a window is not only bright, but also not easy to leak air, and it will be especially warm in winter!"

"Master, this glass is expensive, so not many people can afford it?"

Li Shimin said.

"Forehead!"

Li Xuan couldn't help being taken aback, "I don't know how much the prince thinks a piece of glass the size of a window will cost?"

Li Shimin didn't understand why Li Xuan had such an expression, but after thinking about it, he continued: "Hu merchants sell a piece of colored glaze the size of a palm for ten guan, and although the cost of this kind of glass is relatively low, they all sell for one hundred yuan. You can do it!"

"My lord, if a piece of three-foot-square glass is priced at ten guan, is it still expensive?"

"Ten strings?"

Li Shimin's expression was slightly moved, "The cost of such a large piece of glass is two hundred coins, plus various expenses, is ten guan silver a bit cheap?"

As he spoke, a trace of reluctance flashed across Li Shimin's face.

After passing by the objects on the sofa, Li Shimin understood that the money earned by these objects was all his.

"My lord, who said that such a large piece of glass costs two hundred cash?"

And Li Xuan was also taken aback.

How could he not know that it took two hundred cash to burn such a large piece of glass?

"This matter is cleverly calculated, isn't it?"

Li Shimin was also taken aback, while talking, he also looked at Li Chengqian who was at the side.

"My lord, two hundred Wen can cover such a big glass!"

Li Xuan sighed lightly, feeling a little helpless.

"Gao Ming, are you so calculating?"

After hearing this, Li Chengqian hurriedly stepped forward and reported to Li Xuan: "Master, I remember that when firing these glasses, a total of more than 600 yuan was spent on various materials. Remove the remaining materials and throw them away for firing. The material used to forge the iron pillars at that time, and the boring used when firing these glasses, were about eight pieces, and a total of about 40 yuan of three-foot-square glass was fired!"

"Therefore, Gao Ming calculates that the cost of a three-foot-square piece of glass should be two hundred cash!"

After speaking, Li Chengqian looked at Li Xuan expectantly.

However, Li Xuan's face was flat, he just nodded slightly, and then looked at Cheng Chusi and Li Chongyi who were standing aside.

"All six of you do the math, how much should a piece of three-foot-square glass cost?"

"what?"

Hearing this, Li Chongyi and Changsun Chong couldn't help being surprised.

They just stood aside and joined in the fun, so why were they involved?

"Ah what, I'll wait for you for a quarter of an hour! If anyone fails to answer the question, they will be punished for washing dishes for ten days!"

As soon as they were punished for washing the dishes, the six of them couldn't help but look sad.Especially Cheng Chusi and Yuchi Baolin, who had just finished the punishment time, and now they had to be punished to wash the dishes.

"Do you still remember what Gao Ming said just now?"

Thinking of something suddenly, Cheng Chusi couldn't help leaning close to Yuchi Baolin's ear, muttering in a low voice.

However, Cheng Chusi obviously underestimated his loud voice, no matter how much he suppressed his voice, the words he spoke were just like other people's normal words.

Listening, Li Xuan couldn't help but glared at Cheng Chusi.

As for Chang Sun Chong and Li Chongyi, although they didn't speak, their eyes were thoughtful.

"Master, my disciple's answer is the same as Gao Ming's. A piece of glass measuring three feet square costs two hundred cash!"

Li Chongyi stood up, cupped his hands and said.

"Master, my disciple's answer is also two hundred words..."

"Master, disciple..."

Following Li Chongyi's lead, Fang Yizhi and Cheng Chusi also stood up one after another with positive expressions on their faces.

"You are so sure that Gao Ming is the correct answer?"

Li Xuan said leisurely, letting Changsun Chong and the others change their expressions and feel uneasy.

On the contrary, Cheng Chusi had a proud face, and he was sure that the correct answer was what Li Chengqian said, "Return to Master, the result of the disciple's calculation is the same as Gao Ming's result!"

Changsun Chong and Li Chongyi on the side, although they were very cautious not to be the first birds, but they all showed a trace of complacency in their eyes.

"Hmph, everyone will copy this question fifty times for me tomorrow!"

But he didn't want to, Li Xuan's face darkened, and he said directly.

Hearing this, the faces of Li Chongyi and the others all changed drastically.

And Li Shimin and Li Chengqian also quickly looked at Li Xuan with puzzled faces.

"Dare to ask Master, why is this?"

Chang Sun Chong asked hastily.

"The cost of a piece of glass, why do you want to include the waste that has only been tested so many times?"

Li Xuan pouted, with a helpless expression on his face. This is the defect of not brushing the questions. Such a simple question can be calculated wrong.

"The cost of a piece of glass will not exceed [-] Wen!"

"What, twenty Wen?"

Hearing this, Li Shimin couldn't help being surprised.

And Li Chengqian, Changsun Chong and the others also stared at the glass on the window in a daze, with disbelief on their faces.

"Master, how is this possible?"

"Why is it impossible?"

Li Xuan glanced at Li Chengqian, "How much plant ash, quartz, sand, and soda stone do you need to burn a piece of glass? It's not like you don't know, you just need to do some calculations to get the answer!"

After listening, Li Chengqian froze in place.

As for Chang Sun Chong and Li Chongyi, their eyes lit up and they quickly calculated.

After a few breaths, everyone stood there blankly, without asking, they knew that the answer they calculated was similar to what Li Xuan said.

……

Chapter 86

"So, many people can afford this kind of glass?"

After a long while, Li Shimin still looked back with a happy expression on his face.

"Exactly!"

Li Xuan nodded lightly, "The price of a piece of three-foot-square glass is consistent, as long as the family is not too poor, they must be able to afford it!"

Of course, when talking about this, both Li Xuan and Li Shimin automatically excluded those farmers.In any case, glass is an expensive consumable. Unless the farmers are rich peasants, landlords and gentlemen, they will never waste any money buying consumables.

"I don't know Master, can you give me this glass to sell?"

After listening, Li Shimin asked with a look of expectation.

"My lord wants to sell it personally?"

Hearing this, looking at the happy Li Shimin, Li Xuan looked a little strange.

Seeing this, Li Shimin seemed to realize something, smiled embarrassingly, and said: "The family is big and the business is big, and the family needs a lot of money!"

"My lord misunderstood!"

Li Xuan chuckled lightly, "I mean, these glasses were fired together with Gao Ming and Li Chongyi and others. Therefore, I also want them to participate in the sale of these glasses, otherwise There are so many good things that make money, but these boys, as my disciples, are still poor, if they say it, others will say that my master is abusing my disciples!"

After saying that, Li Chongyi and Changsun Chong couldn't help but their eyes lit up, and they looked at Li Shimin expectantly.

Isn't the biggest motivation for them to come to worship their master as their teacher to earn pocket money?

Although the original intentions of several people have changed now, who doesn't like making money?

Moreover, they all use the fruits of their labor to make money. No one can experience this sense of fulfillment.

"I see."

After listening, Li Shimin realized that he was thinking too much, and bowed his hands solemnly to Li Xuan.

"I hope Master can rest assured that I will discuss such a big matter with them, Aye!"

To Li Shimin's words, Li Xuan could only nod his head.

This is the tragedy of being a hermit (scientific research dog) in the mountains. In this era, one has no power and no power, and can't even make money from his own inventions.

However, after seeing Li Chongyi and the others who were also full of disappointment, the disappointment in Li Xuan's heart gradually calmed down.

"That's the end of today's lesson. After a while, you all go back with the prince!"

"Yes, thank you, Master!"

Hearing this, Li Chongyi and the others immediately beamed with joy.

Immediately, followed by Li Shimin who couldn't wait, and rushed back.

……

And in Chang'an city.

After Cheng Zhijie, Li Xiaogong and others watched Li Shimin go out, they stayed at the mansion, waiting anxiously.

Therefore, after Cheng Chusi and others followed Li Shimin into the city, a group of guards from the duke's mansion quickly ran towards the duke's mansion.

At the same time, Cheng Chusi and others followed behind.

"Aye, I'm back!"

"Your Majesty went to talk to your master about glass, did you meet him?"

"Aye, Master agrees to allow His Majesty to sell the glass, but because I assisted Master in firing the glass, Master suggested to His Majesty that I should share the profit and earn some pocket money for me!"

"Are you waiting for pocket money? Nizi, do you know how much money that glass can earn? Are you not afraid of getting tired when you spend so much money as pocket money?"

"Aye..."

"Shut up, what's the matter, wait until I find His Majesty and come back!"

After finishing speaking, Cheng Zhijie, Li Xiaogong and the others hurried to the palace under Cheng Chusi's and others' gloomi gaze.

Along the way, I was full of excitement.

The quality of the glass is even better than that of the colored glaze in the hands of Hu merchants. If they can get a hand with it, they can earn one hundred thousand guan a year no matter what.

Wouldn't the days after that be full of joy?

Of course, this is the case where they don't know the cost of the glass.

Just after Li Shimin returned to the Taiji Palace, before he could sit down and take a breather, he heard a rough sound, the tiles of the shaking Taiji Palace were clanging.

"Your Majesty, Old Cheng is asking to see you!"

"Your Majesty, Li Xiaogong begs to see you..."

"Let them in!"

Li Shimin waved his hand helplessly and said.

"Yes, Your Majesty!"

After listening, Li Wei on the side hurried out.

Immediately, a group of veteran killers came in from the gate of the palace.

As soon as he entered the palace, he walked straight towards Li Shimin.

"I have seen Your Majesty!" "I have seen Your Majesty!"

After saluting, a group of people quickly looked at Li Shimin.

"Hey, Your Majesty, I, Old Cheng, heard from my little bastard that the master has agreed to let you sell the glass. And my little bastards have also done their best, can we get involved?"

"That's what the little master said."

Hearing this, Li Shimin nodded helplessly and said.
