"It's so comfortable, it doesn't smell like a sheepskin jacket, it doesn't prick the meat, and it's not afraid of shedding, it's really good." The big hand caressed the new clothes, and Li Keshi admired again and again.

"What's better is that this quilt is warm and not heavy, in Daxing before, you have to cover several quilts in winter, and those who are weak can't feel the breath, this is estimated to have a bed, it is enough." Han Qianxun lifted the quilt and wrapped it in his hand and said.

"This is still very ordinary, and when you use Jiangnan silk and down in the future, that is the best thing." Zou Yu couldn't help but miss the down jacket and silk quilt that began to be in the future. However, it reminded him that the feathers and fluff of the poultry on the farm should be collected.

Just do it, immediately let people give a notice, all the poultry, feathers and fluff can be sold to the government.

"Hey, hey! With these, you don't have to worry about the cold in the future, this is just Liaodong, like a little south, I'm afraid it's just this one, you can walk outside in winter. Zhang Zhongjian took off his clothes, wiped the sweat from his forehead and said.

"We have a natural advantage, we have a lot of wool, so we leave a batch as a herdsman's remuneration, and we are selling some of it to our own people, and the rest is sold to Silla." Zou Yu said.

"Why don't you sell it to the Khitan nearby?" Zhang Zhongjian asked.

"Sell it to them, and the price of wool should go up, and although they can't make it so good, they know what we're going to do with it. So it will take at least two years before selling it to them. Now everything is kept secret, waiting for the autumn and winter season, and it will be sent. Zou Yu explained.

The wool clothes are made by the women of the Ya tribe, so that the news can be kept as confidential as possible, which Zou Yu has long considered, after all, this thing is easy to imitate, even if others can't make it taste, they can't make it fluffy, but they gave others a hint, who knows what will happen. Getting rid of grease is not only a way to get rid of salt.

Liaodong said that the rich is very rich, but relatively speaking, it is also very poor, this is mainly because of the cold weather, the tools are simple, many things can not be developed, so there is no kind of resources, in fact, they are very precious, and now a new way of wealth has been developed, of course, it is worth rejoicing. Especially from the Khitan, the Xi people continue to send back wool, which makes people look very festive.

The previous time he won the battle against the Heishui Tatar clan, although Zou Yu said that he didn't want the territory, the Khitan Mohui still honestly said that he would only graze and would not occupy it. Of course, Zou Yu will not be polite, after all, if he does not occupy it now, it does not mean that he will not need it in the future.

Arrange manpower to explore the terrain first, this is the most important point, not only Han Qianxun and other generals know, Zou Yu also knows this, and even attaches more importance to it, now the county guard has a sand table and a detailed map that has been explored nearby.

The benefits of this move are naturally very many, no, a large open-pit coal mine was found on the edge of the black water. This can make Zou Yule bad, these two years of burning kang, boiling salt, smelting copper, the need for too much wood fire, although after the trees are cut down, and replanted, but it has gradually been unable to make ends meet, especially the big trees, it has been necessary to go farther, it is enough. The advent of coal makes up for this very well.

"Blackstone is very common! Every year, many people die of poisoning, and generally only ordinary people, or iron smelting, are used. Hei Sumei was very puzzled why Zou Yu was so happy that she couldn't close her mouth. Fortunately, Zou Yu recently gave the two of them a set of cashmere clothes, which made her attitude towards Zou Yu much better, and she no longer talked back.

"This is a good thing, with this, we will no longer be short of fire, this Liaodong is really a treasure." Zou Yu said happily.

"You're lying to me again, don't think I don't understand, black stone is difficult to burn, and there is charcoal poison, where is a good thing." Hei Sumei thought that Zou Yu was teasing her again, and said with a frown on her delicate nose.

"Who lied to you, it's that others don't understand, these things are in the hands of your brother Yu, but they are all treasures." Zou Yu smiled confidently.

"Tell me how to do it." Hei Sumei looked at Zou Yu, with a hint of shyness in her big eyes and joy, and asked by pulling his sleeve.

"It's very simple, crush the coal, which is the black stone, the more broken the better, and then add a little yellow mud, which is not only easy to burn, but also lasts!" Zou Yu explained to her with a smile, well, of course he wouldn't say that this was about a long-lasting topic, after all, boys, facing a beautiful woman alone, it is inevitable that they will sometimes make a vague joke.

Of course, Hei Sumei didn't understand, and asked with a puzzled face: "It's so simple?" ”

"Of course not! It is also necessary to make a mold and let it be shaped, and the most important thing is to add wood powder to the outermost layer, so that it is easier to ignite. Zou Yu secretly laughed and said with a smile.

Seeing that she was still a little unconvinced, Zou Yu was angry, and asked someone to prepare immediately, according to his order, and quickly prepared everything, and then he personally took action, made the coal into powder, added yellow mud, mixed it with water, added sawdust to the outermost layer, and then put it aside to dry, and did more than ten in a row before stopping.

After waiting for an hour, he brought the coal all by hand, Zou Yu did not use the traditional cylinder, but made it square, because it is convenient and there is not so much iron to make the furnace at present, so the square is the best, and there is no problem where to put it.

Under the watchful eyes of everyone, a little dry wood picked up everywhere ignited the coal, and then with a little blue flame it slowly burned, and some pungent smell came out.

Zou Yu asked about this taste, not only did he not feel a little disgusted, but he almost burst into tears, there was always a trace of something familiar to future generations.

"Brother Yu, you are amazing!" Hei Sumei tilted her head and looked at it again, and said admiringly.

"The next thing is to see how long it can burn." Zou Yu cleaned up his mood and stared at the coal and said.

"But the flame is a little small." Hei Sumei frowned slightly and said.

"This is like this, it looks like the fire is not big, but the cooking effect is the same, and it doesn't need to be supervised, it's very convenient, but you have to make a new stove." Zou Yu explained.

"Oh!"

Then several people waited slowly, and it was not until nearly an hour later that the flames slowly extinguished without a trace of temperature.

"Make a stove that is just so big, the heat will not be wasted, the combustion will last longer, when not in use, you can also block the air outlet, put a pot of water on it, so that there is hot water to use all day and night, it is best to connect the kang to this, and there is no need to burn the wood fire separately in the future." Zou Yu explained to her one by one that this is completely a cross-era thing, especially for the people in the north, it is very important.
