"I didn't expect that Master's firing skills are so good, and he can produce such exquisite and transparent glass!"
Sitting on the sofa in the house, Li Shimin couldn't help but raised his head from time to time and looked at the window.
It’s so exquisite!
Moreover, sitting in the house, you can clearly see everything outside the house through the glass without opening the door or windows, and the house is so much brighter than before?
Suddenly, Li Shimin couldn't help but feel itchy.
"Your Majesty, you're welcome. This is just a way of life, little Doyle!"
Li Xuan looked calm.
"The way to live a life based on things?"
Li Shimin on the side couldn't help but look surprised, and then he felt vigilant in his heart.
"I dare to ask Master, what is the way of living by studying things? I wonder which sage's school this way belongs to?"
"To know something, you need to examine it, and then you will know it!"
"Your Majesty, all the affairs in the world have their own laws. The way to live a life of studying things is to personally explore the laws of these things, and use these laws to create better objects and improve our lives!"
After listening to Li Xuan's solemn lecture, Li Shimin's mouth twitched. To put it more bluntly, didn't he just want to be like those craftsmen and concentrate on making better objects to enjoy life?
"So that's it, Master is indeed an expert hermit!"
"Thank you for the compliment, Your Majesty!"
I don't know if Li Xuan understood Li Shimin's words, but he still looked calm.
"May I ask Master, what is the purpose of forging this glass?"
Li Shimin seemed to have discovered the true identity of Li Xuan, the 'wonderful man', and he didn't want to dwell too much on it and went straight to the point.
"Of course it's used as a window!"
Li Xuan glanced at Li Shimin strangely, and said slowly: "As the prince has seen, using glass as a window will not only make the room bright, but also not easy to leak, and it will be particularly warm in winter!"
"Master, this glass is expensive. Not many people can afford it, right?"
Li Shimin said.
"Forehead!"
Li Xuan couldn't help but be stunned, "I wonder how much the prince thinks a piece of glass the size of a window costs?"
Li Shimin didn't understand why Li Xuan had such an expression, but after thinking about it, he continued: "Shang Hu sells a palm-sized piece of colored glass for ten pieces. Although this kind of glass is relatively low-cost, it also sells for one hundred.
Guancai can do it!"
"Your Majesty, if a three-foot-square piece of glass sells for 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, isn't ten coins a bit cheap?"
As he said this, a trace of reluctance flashed across Li Shimin's face.
After passing the objects on the sofa, Li Shimin realized that the money earned from these objects belonged to him.
"Your Majesty, who said that such a large piece of glass costs two hundred cents?"
Li Xuan was also startled.
It costs 200 yuan to make such a large piece of glass. Why didn't he know?
"This matter was calculated with great skill, wasn't it?"
Li Shimin was also startled. As he spoke, he looked at Li Chengqian who was standing aside.
"Your Majesty, two hundred coins can be used to cover such a large piece of glass!"
Li Xuan sighed softly, feeling a little helpless.
"Gao Ming, are you so calculated?"
After listening, Li Chengqian quickly stepped forward and reported to Li Xuan: "Master, I remember that when firing these glasses, I spent a total of more than 600 yuan to purchase various materials. Remove the remaining materials, and then throw them into the furnace.
The materials used to forge the iron pillars and the materials used to bake these glasses were probably about eight pieces, and a total of forty pieces of glass that were about three feet square were fired!"
"Therefore, a clever calculation would suggest that the cost of a three-foot-square piece of glass should be two hundred cents!"
After saying that, Li Chengqian looked at Li Xuan expectantly.
However, Li Xuan's face was dull, he just nodded slightly and looked at Cheng Chusi and Li Chongyi who were standing aside.
"All six of you, please do the math. How much does a piece of glass three feet square cost?"
"ah?"
Hearing this, Li Chongyi and Changsun Chong were all shocked.
They were just standing around and joining in the fun, so why were they involved?
"Ah, what, I'll give you a quarter of an hour! If anyone can't answer, they'll be punished by washing dishes for ten days!"
Upon hearing that they were punished to wash the dishes, the six of them couldn't help but look sad. Especially Cheng Chusi and Yuchi Baolin, who had just finished their punishment time and were now punished to wash the dishes again.
"Do you still remember what Gao Ming just said?"
Suddenly thinking of something, Cheng Chusi couldn't help but lean into Yuchi Baolin's ear and murmured in a low voice.
However, Cheng Chusi obviously underestimated his loud voice. No matter how hard he suppressed his voice, the words he spoke were just like other people's normal words.
After hearing this, Li Xuan couldn't help but glared at Cheng Chusi fiercely.
Although Changsun Chong and Li Chongyi did not speak, their eyes were thoughtful.
"Master, my disciple's answer is the same as Gao Ming's. A piece of glass three feet square costs two hundred coins!"
Li Chongyi stood up, raised his hands and said.
"Master, my disciple's answer is also two hundred liters..."
"Master, disciple..."
With Li Chongyi taking the lead, Fang Yizhi, Cheng Chusi and others also stood up one after another with affirmative expressions on their faces.
"Are you so sure that Gao Ming is the correct answer?"
Li Xuan said leisurely and asked Zhangsun to rush to several people. Their expressions could not help but change, and they felt uneasy in their hearts.
On the contrary, Cheng Chusi looked proud, confirming that the correct answer was what Li Chengqian said, "Back 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 careful not to stand out, there was a trace of pride in their eyes.
"Hmph, tomorrow each of you will give me this question and copy it fifty times!"
But he didn't want to, Li Xuan's face darkened and he said directly.
Hearing this, Li Chongyi and others couldn't help but change their expressions.
Li Shimin and Li Chengqian also looked at Li Xuan quickly with confusion on their faces.
"May I ask Master, why is this?"
Changsun Chong asked quickly.
"The cost of a piece of glass, why do you have to include the waste that has been tested so many times?"
Li Xuan curled his lips with a look of helplessness on his face. This was the flaw of not answering the questions. He could make mistakes on such a simple question.
"The cost of a piece of glass will not exceed twenty cents at most!"
"What, twenty coins?"
Hearing this, Li Shimin couldn't help but be surprised.
Li Chengqian, Changsun Chong and others also stared at the glass on the window with expressions of 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 alkali stone are needed to make a piece of glass? It's not like you don't know, you can get the answer just by doing some calculations!"
After hearing this, Li Chengqian froze on the spot.
As for Changsun Chong and Li Chongyi, their eyes lit up and they quickly started calculating.
After a few breaths, everyone stood there blankly. Without asking, they knew that the answer they calculated was almost the same as what Li Xuan said.
