Cui Shanyou was "entrusted with an important task" by Li Er and was sent to the Hongwen Museum for history revision.

Today's Li Zexuan not only has won the emperor's heart, but the forces related to him can be described as entwined, almost equivalent to more than half of the entire Tang military forces! The most important thing is that Li Zexuan may still have a very terrifying thing hidden in his hands. The original Snake Spirit Mountain Seven Cultivation Sect was destroyed overnight, and everyone in the family still remembers it in their hearts!

Such a Li Zexuan, the Zheng family is still reluctant to provoke them. It cannot be said that the Zheng family is afraid, but they do not have much grudges with Li Zexuan, and it is not worth getting to the point where the fish die and the net breaks!

The family is all about profit!

The days suddenly became more leisurely, and after several days in a row, no one came to harass Li Zexuan.

As the New Year is approaching, the weather is getting colder and colder. Although it hasn't snowed yet, Chang'an is located in the north of China. In winter, the north wind is often howling, and the wind blows on the face like a knife. Li Zexuan has been thinking about whether to let the students of the academy take winter vacation in advance. After all, the weather is really cold!

The severe cold weather made Laner, who likes to go out crazy on weekdays, also reluctant to go out again. The little girl stayed at home all day long, wrapped in thick fox fur, and wearing cotton clothes inside, and she looked even more round. cute!

Note that the cotton clothes are not the same as cotton clothes. Although there was cotton in the Tang Dynasty, it was only used as a flower for ornamental purposes. At this time, it was not used as a cotton jacket. The so-called cotton robe was made of cotton It is made of extremely high-grade silk wool. This kind of silk wool is also called "绩", which is mainly used to make cotton robes. .

This kind of cotton robe made of silk wool has excellent thermal insulation effect. Of course, the cost is quite expensive. Only a wealthy family can afford it!

However, for the poor, it is a luxury to wear a robe with "绩", and most of them wear "绊". The so-called "绊" is a robe filled with a lower-grade silk wool, and the cold protection effect is also extremely poor. , Even when many celebrities are unwilling, they have made troubles for this. For example, Zeng Zi, a famous scholar in the Warring States period, wore this when he was unwilling. In the winter, when he rolled up his sleeves, he would see his elbows. Therefore, he contributed an idiom: stretched!

Of course, in addition to the silk wool material, animal fur clothes are also necessary to keep out the cold, but high-end fur clothes are basically the patent of the rich and aristocratic, and of course the common people cannot count on them.

It is conceivable that in the era of no cotton, winter was a difficult season for most ordinary people. Listening to the poems of the great poet Du Fu, you will know that the cloth quilt has been cold as iron for many years, and the arrogant child is crooked. That is, the quilt is as cold as iron!

This is still Du Fu's house in late autumn, what is the colder winter like? Just thinking about it makes you shiver.

Therefore, Li Zexuan often cannot help but sigh recently, in an ordinary winter, I don't know how many poor families will freeze to death!

"Brother! You see it's so cold, think of a way!"

Lan'er pestered Li Zexuan and said pitifully, "It's cold outside, but it's also cold inside!"

Although there is a charcoal pot at home, she doesn't know what her brother is crazy about, saying that the window must be opened to ventilate the charcoal pot at home, but in this way, it is a real double world! The front is heated by the fire, and the back is cooled by the cold wind!

At this time, she began to envy Li Zexuan. Don't look at the cold weather, but Li Zexuan only wore a few single clothes because of his internal strength, but his big hands were always so warm, so Laner saw At home, Li Zexuan always likes to put his hand in Li Zexuan's palm to keep warm!

"Heh~! You little girl! This summer is hot and winter is cool. How can your brother have the ability to change the weather for you~?"

Li Zexuan laughed a little after hearing this cute request from Xiao Kawai.

Lan'er blinked and said playfully, "Hee hee! Big brother can't change the sky, but there must be other ways! Big brother is the best!"

"Oh! You little girl, it's cold even if you have a charcoal pot to roast, and you don't go out to see if there are people outside who can burn charcoal from the Li family?"

Mrs. Li said to her daughter angrily.

Laner flattened her mouth and couldn't deny it.

Li Zexuan said happily: "If you want to talk about this method, it's not without..."

"Master, Fu Bo sent someone to send a stove and a batch of strange-looking coal balls, and I told you to try it!"

An idea was popping up in Li Zexuan's mind, and Sanbao suddenly came in from the door and bowed.

"Oh~? Haha! Just in time! Where are the things! Move in!"

Li Zexuan was delighted and said loudly.

Since the last shipment of bauxite, Fubin sent people to bring back several shipments of iron ore, sulfur ore, and coal mine! And the blast furnace of the workshop has been almost built recently, so Fubo began to study how to make honeycomb. As for the kind of coal stove that burns briquettes, the structure should not be too simple. Fubo directly asked the craftsmen he trusted to build it!

Li Zexuan gave Fu Bo a very detailed method of making briquettes. It only took two or three days before and after, and the first batch of briquettes was ready. When he thought that he had brought a very practical modern item to the Tang Dynasty Now, how could Li Zexuan be unhappy!

"Master, it's all in the yard! I'll move in for you, little one!"

Seeing that his young master is happy, Sanbao is also happy, he replied with a smile.

Others in the family don't understand Li Ze

Why did Xuan come to be so excited all of a sudden? Old lady Ye asked with a smile, "Xiao Xuan, isn't this just a stove? Are you so happy?"

"Hehe, grandma, this is no ordinary stove, you'll know in a moment!"

Li Zexuan sold a pass with a smile.

After a while, Sanbao and Ah Fu moved in the stove and briquettes together. Li Zexuan stepped forward and took a closer look. A familiar feeling rushed to his mind. Because in appearance, this coal stove and briquettes are very similar to those used in his previous life.

"Brother! Can this thing make people warm?"

Laner looked at the coal stove that was almost as tall as her, and asked in a crisp voice.

Li Zexuan rubbed her little head and smiled knowingly: "Haha! Laner, you guessed right, but there is no reward, haha!"

After all, he didn't care about the little girl's coquettish behavior, he went up to pick up the tongs (this thing existed before the Three Kingdoms), clipped a piece of honeycomb, and put it in the charcoal basin, then he raised his head and said to Mrs. Ye: " Grandma, this thing is made of briquettes, I call it briquettes! You'll know the magic of this thing in a moment!"
