The Han is barren, and this does not refer to the land but to the material. In Yun Xiao's view, this is simply a physical desert. Everything is lacking, from food, clothing, shelter and transportation to spiritual life.

"I can't live this day."

Yun Xiao was full of resentment when he saw the radish beef stew in the soup bowl, couldn't he take the potato beef stew?

…… Potatoes are still in the Americas, and it's not hard to get a bite. If it weren't for the fact that I brought the chili pepper to Dahan by mistake, I don't know how many years it would take to eat spicy food. Nowadays, people in the family are almost inseparable from this plant, which turns fiery red when it matures, and there is a tendency for the taste to become heavier and heavier.

It's not that I haven't thought about it in the greenhouse, but the ideal is very plump, but the reality is very skinny. A few cucumbers planted in large pots, wilting and chirping, just don't bear fruit. It's no wonder that such a small amount of planting, coupled with a lack of sunlight. It's no wonder that these fruits and vegetables wilt.

There is no way around it, as papier-mâché windows are in the era of high-tech luxury. Do you dare to imagine such a thing as plastic film? That thing is too high-tech, even if Yun Xiao knows the chemical formula, just getting crude oil is enough of a headache.

"Xianggong, isn't there bean sprouts and garlic sprouts? In this winter, except for the royal family, who eats fresh fruits and vegetables. Even the maidens in the palace are limited in supply, and the output of Wen Tangjian is so much. Last time, I heard that Princess Guantao's house was missing a basket of cucumbers and several people were executed. You're going to eat as much as you want. ”

Luan Ling stuffed the chopsticks into Yun Xiao's hand, and coaxed Yun Xiao softly.

"It's too hard to eat without food. You see my hands are pierced with knives and spears. Yun Xiao stretched out his hand in front of Luan Ling to show Luan Ling, men are sometimes like children. Yun Xiao felt that the childlike innocence in his soul was completely stimulated by the goddess, and Luan Ling, who had given birth to a child, was now like a loving mother, taking good care of Yun Xiao. Treating him more like a son than like a husband, the goddess has a great grudge on this.

After eating two bites of bean sprouts, he put down his chopsticks. I'm really fed up with the days of bean sprouts and garlic sprouts every day, and I feel like peeing smells of garlic sprouts when I eat them, and I can smoke myself.

"I'm full."

Yun Xiao pushed away the rice bowl and walked around the yard with his hands behind his back.

The air in Chang'an is very similar to the air in Yanjing, both dry and cold. Yun Xiao likes this kind of climate. It's cold and domineering. Not like Gangnam. It's damp and cold, and it's as soft as a girl.

Canglan this guy ran in screaming, this thing has excellent dog leg potential. A few days ago, I saw that Yun Xiao was unhappy, so I got Yun Xiao an eagle and said it was for hunting. Yun Xiao was very happy, but the eagle disappeared overnight.

Xiaobai looked at Yun Xiao with innocent eyes. Indicates that the matter has nothing to do with it. But how to explain the eagle feathers on the corners of the mouth? This guy generally doesn't eat live food. If the meat is not cooked, who knows that it will attack this eagle.

Looking at Canglan's cheerful appearance, could it be that he caught something again? Did you catch a little tiger? This is good. Raised up and Xiaobai PK.

Eight stout men walked in carrying a white stone the size of a tabletop. Canglan insisted that every grass and tree on Lishan belonged to the Yun family. This thing can't wait to stamp every leaf with the seal of the Yun family, and now that he has a treasure, he will naturally hand it over to the head of the family to deal with.

A white stone, with pimples on it. The facets are neatly and smoothly raised in geometric shapes, and they look like diamonds from a distance. It looks like a crystal up close, but the transparency of the crystal is far better than this thing. Let people fetch a basin of water, carefully rinse the remaining soil, Yun Xiao is overjoyed that this is a fucking quartz stone.

This is the main raw material of glass in later generations.

"Where did you get this?"

Yun Xiao pointed to the quartz stone and asked excitedly.

"Two miles away from the Houshan Coal Mine, a vein was found, and it was all this thing. It's just that everyone doesn't know what it is? When I saw that this thing was strangely born, I picked a large piece and let people carry it back to the head of the house. ”

Canglan looked like a treasure, very similar to Mu Renzhi on TV, if Yun Xiao fell in love with which Xi'er, it is estimated that the goods would be snatched back immediately.

Didn't say it, such a guy with the spirit of discovery should be rewarded. It's so sweet, I send a pillow if I want to sleep. With this thing, Yun Xiao is eighty percent sure that he can make glass. The quality is not guaranteed, but looking at the purity of this quartz stone, the light transmittance should still be good.

Construction is already underway on the match factory by the river, and it seems that another glass processing plant will be built. In the future, there will be no economic belt along the river, and if you have time, you will not repair the embankment.

As soon as people were excited, they thought about a lot of things, and Yun Xiao took the servants with big shoulders and round waists to carry this thing to the steelmaking furnace of the big hammer. I heard that this thing is going to be heated to 17800 degrees, and even if the best coke is used, Yunxiao still has no bottom in his heart.

The sledgehammer made people build a high earthen platform by the river, which covers a large area of four or five acres. The cold river breeze in winter is the best blower. He also planned to move the steelmaking furnace directly to the top of the hill after the New Year. The winds are stronger there, and as long as you make a huge sail, there are natural blowers all year round.

It's just that the transportation is not very convenient, and Yun Xiao is ready to dig out a mountain cliff and make a primitive winch out. Eight cows pull a huge winch, and the project is huge when you think about it.

The huge iron hammer smashed on the quartz stone, and Canglan watched in amazement. As soon as his expression recovered, he had a painful expression, thinking that the head of the family had destroyed a rare treasure.

"Don't worry, this thing is just a raw material. I'm going to use it to make something you can't even think of. Yun Xiao smiled and patted Cang Lan's shoulder, feeling indescribably happy.

Large pieces of quartz were hammered into smaller pieces, and smaller pieces were thrown into stone mills and ground up. Quartz stone is very hard, and it can only be ground into small particles after grinding for a long time, so Yun Xiao looked at it and left it at that. Let's see if we can burn the glass first.

The roaring fire burned for a whole day and a night, using the finest coke. The big hammer was sucking in distress next to him, and he didn't know what the Hou Ye was going to burn these stones for. I also sprinkled those gray-white lime powder into it, which was white enough to sprinkle lime. In the end, I actually saw Yun Xiao throwing saltpeter into it. I saw that the scalp of the big hammer with strong gunpowder was swollen, and I subconsciously dodged to the side.

And he was puzzled by how he put a lot of yeast in it, wasn't this thing for noodles? How did I use this, but when I saw Yun Xiao's hopeful look, I had to follow it. See what these white stones can burn.

Yun Xiao looked at the big hammer muttering on the side with disdain, I will teach you such technical things as sodium carbonate and calcium carbonate to burn glass? Can you learn what Na2CO3 means?

On the third day, Yun Xiao finally got a pot of melted quartz water. The orange one lay in the trough, so hot that the sledgehammer wrapped his body like a mummy, and poured a lot of water before he dared to go over.

The task given to him by Juzi is very simple, that is, rolling the skin. In order to fully familiarize him with the business, he had already rolled out a basket of dumpling wrappers yesterday. Sledgehammer's brain barely rolled out the sparks, and now he gets irritated at the sight of something that resembles a rolling pin.

However, this thing is easier to make, and the orange-red material is very viscous. Poured into the hopper of molten iron, two people pushed the wheel. Between the two iron mills, a thin layer of something came out, and when he saw this thin layer, Yun Xiao was immediately so happy that he couldn't see his teeth. Hurriedly let the sledgehammer put these things into the hot annealing kiln, and the heated glass would become brittle if it was not decorated.

The technical term seems to be called insufficient stress intensity, and my memory is a little vague. I learned it in materials science, but I can't remember it for too long.

The amount of firewood was gradually reduced under the annealing kiln, and after two days the last firewood was finally removed.

After a day's drying of the kiln, Yun Xiao was the first to rush in.

Pieces of flat glass lay quietly on the shelf, and carefully touched them with their hands. It was also a little warm, so people took a small piece and went outside. As soon as the cold wind pumped, the residual temperature on the glass disappeared in an instant. Looking at the sun, there are bubbles and impurities. If in the 21st century, whoever burns such glass will be expelled from the world.

But in Dahan, this is a high-tech product.

The killers under his command looked at the transparent thing in Hou Ye's hand one by one with big mouths. It's a lot like crystal, but I've never seen a crystal so big and flat. Hou Ye is really a fairy figure, and he can make any kind of thing.

Master Geng took it excitedly, and the beard under his chin was pouted.

"Master Hou, this is a baby. If this thing is installed in the window, there is no need to light candles in the house during the day. ”

After all, I was engaged in construction, and the first thing I did was to think of using this thing in my old business.

"It's not just this purpose, with this thing, we can eat fresh fruits and vegetables in winter. Hehe, let those people in Chang'an eat this thing of dried vegetables. ”

Yun Xiao thought that these days he was either eating dried vegetables or garlic sprouts, and finally there were out-of-season vegetables to eat, and there would be no more knives and spears in his hands. Thinking that you are in the greenhouse, you want to eat cucumbers, you want to eat cucumbers, and you want to eat watermelon. Oops, it drools just thinking about it. Damn, no one is allowed to touch this first batch of glass, and Lao Tzu wants to use it to repair the greenhouse.

Lao Tzu wants to eat out-of-season vegetables.

"Wow"

A crisp broken sound came into Yun Xiao's ears, waking up the Hou Ye who was obsessed with lust from his dreamy state.

The glass was broken, and Master Geng was crying with his hands full of blood holding the broken glass. The old fisherman was embarrassed to sneer with a hammer in his hand.

Don't dare to let this old guy prick his hand badly, Yun Xiao hurriedly persuaded Master Geng.

"This thing is brittle and can't be smashed with a hammer. You always let go, and it's not a joke to prick your hand. (To be continued......)
