Li An told Li Yu and Li Li beside him that the blast furnace he built was used to smelt medicinal jade, not iron, which made Li Yu and Li Li both surprised, and stared at the blast furnace in front of them curiously. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Medicinal jade is the glass of later generations, it is such a name in Datang, a very strange name, and Datang has not mastered the technology of refining medicinal jade, and the medicinal jade in the hands of nobles and royal families is all passed from places farther west than the Western Regions.

In order to make high profits, the merchants of the Western Regions said that the formula of the medicinal jade was so miraculous that even the snow-capped mountain Xuanbing that no one had ever seen before, thus slaughtering the Tang nobles fiercely, and making all the people of the Tang Dynasty convinced of the so-called complex formula of the medicinal jade.

Li Yu and Li Li, as the emperor's grandsons, had of course seen medicinal jade, and were deeply impressed by the transparent beauty and hard fragility of medicinal jade, and they were both shocked and a little skeptical when they heard that the blast furnace built by Li An could make medicinal jade.

Because they felt that they were too misled, they felt that it was impossible for Li An to collect all the materials needed to make the medicinal jade, at least, no one in Datang had ever found the Snow Mountain Xuanbing, and without such a core material, it was impossible for the medicinal jade to be manufactured.

"Li Shilang, medicinal jade is a specialty of a remote country in the west, I heard that there are a lot of materials needed, can you really make medicinal jade?"

"Li Shilang, I heard that Yaoyu needs Snow Mountain Xuanbing, but I don't have this in Datang, so how can I make Yaoyu?"

Li Yu and Li Li are both half-grown young men, but they are not three-year-old hairy children, so easy to be deceived, they feel that Li An can't make medicinal jade at all.

"Snow Mountain Xuanbing? My Datang is rich in products, how can I miss this thing? When the medicinal jade is made, you will know that what I said is true. ”

Li An didn't bother to explain too much, in addition, the formula of the medicinal jade can't be told to outsiders, in order to keep it secret, even these working workshop craftsmen don't know what the soda ash powder that Li An transported is, after all, natural soda ash is the cover of the black powder workshop, Li An let some of the manual grinding, directly transported to the processing plant, so it can be regarded as waste utilization, as for the sand, it is for Wang Ba to take a group of male servants to dig in the nearby river, and the digging is very clean, it is the best quartz sand.

The craftsmen lit the coal, began to blow the wind, and poured the mixture of sand and soda ash from the top into the furnace of the blast furnace to begin the refining.

"Li Shilang, how long will it take to refine this medicinal jade."

Li Yu was eager to see the result and asked eagerly.

"This, it takes a lot of time, we have to wait patiently, we can't rush, there are rocking chairs here, let's lie down and bask in the sun! This way time will pass a little faster. ”

Li Ang said and walked to the rocking chair not far away, and lay on it first, swaying in the sun.

After returning to the mansion yesterday, I pampered Yan Ruyu twice, although it was beautiful and comfortable, but it was really tired, if it wasn't for Li Yu and Li Li to see the refining of medicinal jade today, Li An wouldn't have gotten up so early? At this time, the sun has just risen, and it is still a windless weather, so it is a good pleasure to catch up on sleep while basking in the sun.

Li Yu and Li Li glanced at each other, but they had no choice but to follow, and followed Li An's example, lying on the rocking chair and basking in the sun.

This experience is incredible, these two people are all addicted, staggering to enjoy it with their eyes closed, and they have long forgotten about the matter of Yaoyu, and even fell asleep unconsciously.

After all, when they were separated last night, Li Ang told them that there would be good things to show them today, they were anxious all night and didn't sleep well, and this morning, they got up in a hurry, and naturally they were a little tired, so it was the most normal thing to fall asleep while shaking.

The three of them fell asleep comfortably, in order to prevent them from catching a cold, Duan Xiushi asked Wang Ba to find three clean small quilts, cover them, and keep guarding them.

"Li Shilang, it's already noon."

When it came to the meal, Duan Xiushi saw that none of the three of them had woken up, and reminded Li An in his ear.

"Ugh."

Li An responded in a daze, then opened his eyes and looked at the sky: "Wow, it's noon, I've slept for so long." ”

Originally, I just planned to squint and rest for a while, but I didn't expect that this sleep would have passed all morning, which made Li An a little surprised, it seems that he was too tired to spoil Yan Ruyu yesterday, otherwise he wouldn't have slept for so long.

Looking sideways to the left, Li An suddenly smiled, he was also worried that Li Yu and Li Li would be bored, but he saw that the two of them were sleeping soundly? It's better than you can sleep.

"Hey, where did you get the quilt?"

Li An lifted the quilt and looked at Duan Xiushi.

"Seeing that the squire and the two imperial grandsons were asleep, he was worried that you would catch a cold, so he asked Wang Ba to prepare a quilt."

"Haha! Duan Xiushi, your heart is quite fine, more delicate than a woman's heart, well done, thank you. ”

Li An praised Duan Xiushi, and reached out to lift the quilt on Li Yu and Li Li, reminding: "King Guangping, Shilang, it's already noon, aren't you hungry?" ”

"Ahh It's noon. ”

Li Yu was sleepy-eyed and lazy, and continued to lie down slowly, his face full of happiness.

Li Li stood up and shook his head to sober himself up.

"Li Shilang, you really enjoy it, it's so comfortable to lie on a rocking chair and sleep in the sun, is it the first time for Xiao Wang to sleep like this?"

Li Yu stood up unsatisfied and stretched again.

"If King Guangping likes it, he can sleep like this every day in the future, especially at noon, make up for sleep, and in the afternoon, the whole person will look very energetic."

Ang Lee seriously suggested that in the future generations, even students with heavy study tasks would take a nap at noon, so that they could devote more energy to studying in the afternoon.

"Forget it! It's not much of a problem here, if it's in Baisun Academy, it will definitely be high-profile, and it's not good for those ministers to know, they will say that I'm lazy, not like an emperor's grandson. ”

Li Yu is very sober, obviously, he must have done something before, he was caught by the ministers, so there is a shadow in his heart, he is afraid of the ministers, of course, if he is caught by a tendon like Wei Zheng, no one will feel good, even Li Shimin is so frightened that he covers the bird to death.

"Li Shilang, why hasn't the medicinal jade been refined yet?"

Li Li walked towards the blast furnace for refining medicinal jade and asked expectantly.

Li An stepped forward to check it and felt that it was about the same, but it would not be wrong to remove the impurities after refining for a while, besides, it was already noon, and he was very hungry, so it was not too late to open the furnace after lunch.

"Eat lunch first, after eating, the medicinal jade can be baked, and when the time comes, you can see the medicinal jade I have refined."

Li An was really hungry, so he took Li Yu and Li Li to eat first, and after eating, he came over to open the furnace and fixed the glass liquid in a special container, so as to condense into the desired shape.

At lunch, Li Yu and Li Yu both ate quickly, they wanted to see the medicinal jade refined by Li An earlier, after all, they always felt that this matter was a bit unreliable, if the medicinal jade was so easy to refine, why had no one refined it before in Datang? But when they thought that Li Ang had invented black powder, which was also very complex, they felt that it was still possible, and the curiosity in their hearts suddenly increased a little.

After lunch, Li An took the two to the blast furnace as promised, and instructed everyone to prepare for the furnace.

"King Guangping, Shiro, and the freshly baked medicinal jade are relatively hot and easy to hurt, so let's stand back a little."

Li An was worried that the hot glass liquid would burn the two imperial grandsons, so he hurriedly took the two of them back a dozen steps, and ordered the furnace to be opened immediately and the glass liquid was poured in.

As the hearth was called, a large amount of hot glass liquid gushed out and dripped into the specially made containers, and continued to gurgle and steam.

"Li Shilang, this burnt water is medicinal jade?"

"That's right, after they cool down, you can see, don't worry, it's winter, the temperature is very low, and the cooling will be faster."

Li An patiently explained, so that Li Yu and Li Li should not be too anxious, in addition, Li An will also give each of them one of the finished medicinal jade products as souvenirs, of course, it must be processed a little.

Li Yu and Li Li looked at the steaming medicinal jade liquid curiously, imagining what would happen to these things after they cooled, whether they would be as transparent and beautiful as the medicinal jade they had seen before.

After a long while, the temperature of the medicinal jade gradually decreased, and Li An immediately stepped forward to carry out the necessary processing of some of the semi-cooled medicinal jade to meet his own needs.

For example, blow out a few beautiful flowers on the surface of the medicinal jade that is about to be shaped, or treat the burrs to make the medicinal jade smooth, and once it is completely cooled, it is very difficult to polish.

"Li Shilang, can we blow this thing too?"

"No, it's too dangerous, besides, you won't, when it's done, I'll give you a small gift, you just wait to receive the gift."

Li An vetoed Li Yu and Li Li's help, and asked the guards to pull them farther away.

Soon, the glass was completely cooled, and all the containers that Ang Lee needed were ready.

Li An picked up two pure copper packaged medicinal jades, handed them to the two, and quipped: "Look at yourself, are you very handsome." ”

Li Yu and Li Yu frowned and looked at the medicine jade in their hands, and suddenly opened their mouths wide in shock, their faces were truly displayed in the medicine jade, it was clear and unimaginable, this was also the first time they knew their appearance so clearly.

In order to verify the accuracy of the mirror, Li Yu and Li Li looked at a mirror together and saw each other's faces, which were almost indistinguishable from real people.

"Li Shilang, the mirror made of this medicinal jade is much clearer than the bronze mirror, this is also too clear, my God!"

Li Yu looked left and right excitedly, and the more he looked, the more he felt that he was handsome and chic, and the jade tree was in the wind.

People in the world say that women are stinky and beautiful and love to look in the mirror, in fact, men are the same, and the more handsome and chic the beautiful man, the more he loves to look in the mirror.

"Li Shilang, I really didn't expect that you really made the medicinal jade, and moreover, you also made it into a mirror, so that in the future, my people in the Tang Dynasty will no longer have to make up on the bronze mirror."

Li Yu was also very excited, but he did not obsessively observe his handsome face like Li Yu, but considered how great changes it would bring to Datang after the mirror appeared, of course, he never thought that the medicinal jade could be made into a mirror, which was seriously beyond the scope of his cognition, and also beyond the cognition of all the people of the Tang Dynasty.

"The role of medicinal jade is too much, not only can it be used to make mirrors, but also windows can be made with medicinal jade, so that during the day, the room will be very bright, in addition, medicinal jade can also be made into a very powerful mirror, which can allow us to see the scene hundreds of miles away, of course, there are more functions, I can't remember it for a while."

Li An said the huge effect of the medicinal jade one by one in one breath, and Li Yu and Li Li, who listened to it, were stunned, which was seriously beyond their cognition, and they were even more stunned.

"Li Shilang, are you telling the truth? Can medicinal jade be made into a kind of mirror that allows us to see things hundreds of miles away? How is this possible, this is also too ......"

Li Yu shook his head again and again, he felt that this was too bizarre, how could a small medicinal jade make people see the scenery a hundred miles away.

Before the invention of the telescope, this was indeed a very outrageous thing, after all, people in this era have never learned optical knowledge at all, let alone what refraction and reflection are, and it is understandable that they cannot understand it.

"King Guangping, you have to remember that in this world, nothing is impossible, such as the medicinal jade mirror you are holding in your hand, isn't it also amazing? But I created it, since I can make a medicinal jade mirror that can see the face clearly, why can't I make a mirror that can see the scenery from a hundred miles away? ”

Li An asked a powerful rhetorical question and looked at Li Yu confidently.

Li Yu's expression looked very shocked, but he soon became very excited, he believed in Li An, he felt that Li An would not lie to him, since he could already make a medicinal jade mirror that was thousands of times better than the bronze mirror, why couldn't he make a mirror that could see the scenery hundreds of miles away? In addition, he is very confident that Ang Lee will invent more interesting and incredible new things in the future.

Worship, very worship, Li Yu's eyes at the moment were full of indescribable admiration, he couldn't understand, Li An was only a few years older than him, why did he have such a high ability?

Li Li's expression was a little calmer, but he also admired Li An's five-body throw, in addition, he also wanted to know how Li An had so much knowledge and what he learned from, of course, Li An would not tell them easily, and Li Longji is a good shield, sometimes, only one sentence is needed, this matter is extremely confidential, and you can only tell Your Majesty alone, you can block a large number of curious inquiries.
