In the afternoon, after saying goodbye to Chen Gong, Li Yi went straight to the vegetable greenhouse, he found a random village, and he didn't need to enter the village, so he saw the vegetable greenhouses all over the mountains.

In order to speed up the construction period, Li Yi originally designed a "one-sided slope" greenhouse, which was built extremely simple, made of adobe, not exquisite, but thick and insulated. It was built in the style of 'one slope', one wall was only four feet high, and the opposite wall was no more than seven feet.

With such a simple greenhouse, a few bricklayers can build a brick in a day. And Li Yi has thousands of old farmers here to help, and the construction will naturally be fast.

Li Yi's greenhouse, due to its good light transmittance, can form a greenhouse effect, so basically do not use much fire, only need to cover the roof of the shed with straw mats at night, and remove it in the morning, except for a little fire to raise the temperature when it is extremely cold.

Tang Yi said with a smile: "It's not bright, but it's also insulated." In winter, just cover the roof with straw mats at night and remove them in the morning, except for a little fire to warm up when it is extremely cold. ”

As for preparations such as straw mats, as early as when Li Yi was studying glass, he had already instructed Bingyu to start doing it, so now there is no shortage of this thing, the difference is glass.

As soon as Li Yi entered the village, he was recognized by several gods, who all came early in the morning and lived here in the future to prevent the glass from being stolen and the greenhouse from being destroyed.

Li Yi asked Shenyu to take him to the greenhouse where the glass was installed, and when he got there, he was full of people inside and out, and he was more curious about the vegetables in the greenhouse, but now he saw the strange thing of glass, and he was even more shocked.

In fact, Li Yi has always been a loss-making business, glass in the Tang Dynasty is definitely a luxury, once Li Yi takes it out to sell, just a greenhouse glass, can definitely make them rich overnight, so, Li Yi ordered, the glass in this greenhouse will never be disassembled and sold, if it is broken, you can go to the county government to report for a new one, but it costs money to change, but it is cheaper.

Li Yi didn't make a noise, and the people didn't know him, there were many people who came and went to watch the greenhouse these days, and there was no shortage of people like Li Yi who were full of nobility, so they didn't mind.

The glass of this greenhouse has already been installed, it should be the first batch of installation, and now it is being experimented, the wooden gate has blocked the greenhouse tightly, and the sun at noon is still very hot, so, after a noon irradiation, the indoor temperature should rise sharply.

Li Yi quietly ordered the catcher to open the door.

When the people saw that the arrest was about to open the door, they all rushed inside, wanting to see it, but they were arrested and stopped quickly, and everyone was still very afraid of the divine catch, so in the end, they decided to enter in batches, with only nearly twenty people each time.

Li Yi is the first batch to enter, this is a one-acre greenhouse, it is still very spacious, Li Yi entered, a sultry feeling came to his face, feel it, Li Yi smiled slightly, temperature, light, humidity are all alive, this greenhouse vegetables have been successful eight layers.

Li Yi felt the change in temperature inside, and the people who came in with him had already exclaimed.

"It's so warm! It's almost winter, how can it be warmer than at home? ”

"Yes, if you live here this winter, you won't be afraid of the cold anymore!"

"No, it's better this winter!"

"Hey, have you noticed it, it's so bright inside, it's no different from outside!"

"Yes! It should be caused by the above things, and if you use it to build a house, it will be so enjoyable. ”

"Humph! The beauty you think, this is the county lord who spent 7749 days to invent it, this is a sacred object, it is already a gift to lend us to grow vegetables, and you still want to use it to build a house? It's a dream! ”

"Hey! I'm just dreaming about it! But our county master is just a man of God, and he can actually study such a house, hey, with such a house, doesn't that mean that he must be able to grow vegetables? ”

"Well, for sure, in this, it's no different from summer, if you can't grow vegetables, then it's really stupid!"

"No, I'm going back and see how my greenhouse is doing!"

"Alas, I regret it, if only I had built a greenhouse, alas, third brother, can you give me some of your greenhouse?"

"This ..... No, my house is a whole greenhouse, I can't divide it, otherwise, you and your younger siblings come to help us, and I will share your profits! ”

"Cheng, it's decided, thank you third brother!"

"Your own family, you're welcome!"

......

Li Yi listened to their conversation with great interest, and a sense of pride rose unconsciously in his heart, if the vegetable greenhouse technology is really promoted to the world in the future, then he Li Yi will really be famous all over the world, but these can only make him YY in his heart, not to mention anything else, on the problem of this glass, he cut off his idea, but this is okay, Li Yi originally planned to make off-season vegetables a feature of Jinling, as for the resulting reduction in food production, Li Yi does not care, he believes, Once they succeeded in bringing back the rice seeds in the coming year, all the problems were solved.

Li Yi was in the middle of yy, and suddenly remembered a sentence from a few people, it seems that they said that in order to avoid the cold, they want to live here in winter, click, isn't this nonsense? Not to mention that it will be extremely humid after planting vegetables here, and even the temperature is not something they can stand!

However, hot is better than cold, but if you go back and forth between the greenhouse and the home, it will be hot and cold, it is very easy to cause a cold, and even form a flu, in ancient times, typhoid fever can be fatal.

Thinking of this, Li Yi couldn't help it, he almost ignored this problem, it seems that the kang and coal stove really have to be promoted as soon as possible, otherwise something big will really happen.

Li Yi was worried, walked out of the greenhouse, casually instructed Shenyu to say a few words about safety, and spurred the horse to rush back.

Li Yi was thinking about this problem along the way, but when he arrived at the county seat, Li Yi was relieved, for ordinary people, you can promote the ondol, with this, basically there is no worry about the problem of cold and warm, and the ondol is also very easy to build, anyway, with the experience of building a greenhouse, it is really simple to build a soil kang. Therefore, it is not difficult to solve Fang Cai's problem, he is just too worried.

Thinking of this, Li Yi is not in a hurry, his task today is to inspect, just now he saw the vegetable greenhouse, and now he wants to go to Qinhuai River to have a look.

Qinhuai Water City is a project that Li Yi has always been concerned about, the reason why he is so anxious is because of the needs of the vegetable event, and the other is also because he will rarely come here next year, therefore, he wants to salvage the foundation of Jinling before leaving, he believes that if it is not him, another person, if you want to build Jinling Water City, it will be difficult, the official's eating and taking cards is a major crux, the world is not bad for money, not greedy for money, and will make money Officials except Li Yi, he really can't think of a second one.

Thinking about it, Li Yi thinks that he is too great!
