My zoo is connected to the Tang Dynasty

Heavy snow is raging!

Day 5

Li Yi's production of "Huokang" was finally passed on, because of the relationship between "radio", each city got the detailed production process as quickly as possible, and then naturally started to make Huokang!

The production of the kang is very simple, rich people can use bricks, because the bricks are resistant to high temperatures, they are originally fired, and those who have no money are used yellow mud, after the yellow mud is pasted, add water to boil dry, it is the same as burning porcelain or pottery, and it is a fire kang after it is made!

The advantage of adobe is that it is cheap, this is not modern, in modern big cities, if you want to find mud, you can only dig in the flower beds, but in the Tang Dynasty, when you go out and turn left, it may be all mud......

Then add plant ash and you can become a wall!

The most important thing about the fire kang is the thermal circulation channel inside, as well as the channel for dispersing gas, fortunately, the craftsmen of the Tang Dynasty have their own technical instructions, which are common to craftsmen, how many angles and turns, how high, or something, are constant standards!

With the standard, it's quick to make!

Because it is a holy decree, it is used all over the country!

Of course, in fact, the fire kang was already available in the Western Han Dynasty!

But it's still not popular enough, let alone the Western Han Dynasty, even if it's modern, do you see the popularity of the ondol?

The South doesn't freeze into a dead dog!

Li Yi is even if he turned on the air conditioner, he was shivering, and when the cold wind blew, it really froze to his bones!

"All winter, I can be safe!"

Falling home, Li Yi raised his head and laughed, this time it was really stable, he prevented another disaster, a terrible snow disaster, a snow disaster that could freeze tens of thousands of people to death!

In Datang, the warmth technology is not good enough, and people freeze to death every year, and there are quite a few people who freeze to death!

But this year is different, what the family can resist is carried at home, and what the family can't bear, all run to the geothermal side of Li Yi Lane outside the city gate, as long as they can block the wind and snow, it will be enough for them!

Woolen sweaters began to ship like crazy!

The cost price of a piece is 8 copper coins, because the labor costs of the female workers still have to be calculated, and they were originally sold at a loss according to the meaning of the eldest grandson queen, but they were stopped by Li Yi!

8 copper coins, it is already the lowest, if you sell it at a loss, it will not work, the human heart is this thing, it's hard to say!

Of course, the most afraid is the rich people, afraid that they will come to stock up, this is the usual method of the family, you sell it so cheaply, I will buy it all, and then sell it at a higher price!

That's how the food in the hands of the family is operated!

When Li Yi arrived in the palace, a lot of information was in Li Yi's hands, and Li Yi didn't have the information about the woolen sweater, so Li Yi wanted to enter the palace to see the information!

"Selling 30,000 pieces a day, in just a few days, half of the 600,000 pieces in stock were consumed!"

Empress Changsun said excitedly, this is her greatest contribution to the people of the Tang Dynasty!

300,000 pieces, for Chang'an, everyone in the surrounding Chang'an County is already one per person!

Li Shimin was really not at ease, so he asked the village Lizheng, that is, the village head, to count the poor families, and directly sent briquettes and woolen sweaters, and this family probably had to send out 200 Wen!

But Li Shimin himself is happy!

Because he has also made countless bucks!

Heavy snow has made the consumption of the Chamber of Commerce begin to rise, the Chamber of Commerce has floor heating, not to mention, the key is that you can also take a bath, a large pool, the water temperature inside is 37.5 degrees, the most suitable for bathing, there are constantly people to take a bath in it, the beauty is not good!

Of course, if you want to take a bath, there will be more other activities!

Li Yi also opened a casino, this thing doesn't even need a commission, just sift the turntable or something, and you can make a lot of money!

And most importantly, coal!

Li Shimin accounted for 30% here, and in just ten days, more than 30 million coals were sold, of which Li Shimin bought, but more of them were bought by the people themselves!

Even if Li Yi said that 100 briquettes are enough for the winter, people still don't listen and hoard a lot of briquettes, because briquettes plus coal stoves are more convenient than burning firewood!

Li Yi also recycled the layer of carbon formed at the bottom of the pot after playing less in the coal stove!

That's a real goodie!

It can be used for metallurgy, and the steel produced is several times harder than other steel!

Of course, it's also more brittle, which requires craftsmanship!

However, this thing is still very slow to collect, and it can be used on black powder!

Black powder, Li Yi has never known whether to take out this thing, to be precise, he is thinking about when to take it out!

Black powder is the first step to change the entire Tang Dynasty, the emergence of this thing means that the mode of war will be completely changed, gunpowder technology and artillery technology are not developed so quickly, but explosives packs can be easily made!

War, now Datang can't afford to spend war, so Li Yi won't take it out for the time being!

When it's time to fight Goguryeo, maybe you can take it out and use it!

Now let's wait!

No hurry!

30 million briquettes, the price of each is 10 yuan, and the actual cost is 1 yuan 10, because the manufacture of briquettes is really very simple, after they are broken, they are wet, and then clamped with a container, and they are good when they are dry!

30 million briquettes, each 10 Wen, that is 300,000 yuan, deducting the cost of the coal furnace, a total of 250,000 yuan!

Actually, this did not make Li Yi return to his roots!

It's just that briquettes are still selling like crazy!

Basically, the sales of 23,000 yuan a day, after the blizzard stopped, the caravan began to set off, taking briquettes and coal stoves, and went to other cities, but at every sales point, there was a Li Shimin's hundred cavalry guards to personally supervise!

First of all, coal stoves cannot be sold privately, they must be sent, and secondly, they must strictly sign the "air ventilation regulations" to sell!

Li Yi is afraid of the dead!

Poisoned by carbon dioxide, Li Yi will resent himself for the rest of his life!

The Tang people are still smart, and they have repeatedly said that if this thing is not ventilated, it will die, if it is dizzy or something, immediately go outside to open the window and open the door for ventilation, and go in after dozens of breaths!

People are life-sparing, and Li Yi's strategy of "signing a contract before selling" makes the family have no loopholes to exploit!

It's all said, let you ventilate, if you don't ventilate, who is to blame for the dead?

The contract is signed by yourself, and it must not be monopolized to anyone, if something happens, Li Yi really won't be blamed!
