Cui Shanyou was "entrusted with a heavy task" by Li Er and sent to Hongwen Hall to repair history, and the prisoners of Guozijian did not dare to make trouble anymore, for this reason, the Zheng family in Xingyang also sent someone to warn Zheng Huaibo and asked him to be honest.

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

With such a Li Zexuan, the Zheng family is still unwilling to provoke, it can't be said that the Zheng family is afraid, but they don't have much grudge against Li Zexuan, and it's not worth getting to the point where the fish dies and the net is broken!

The family is all profit-oriented!

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

Approaching the end of the year, the weather is getting colder and colder, although it has not snowed yet, but Chang'an is located in the north of China, and the north wind often howls in winter, and the wind blows on the face like a knife. Li Zexuan has been pondering whether to let the students of the academy have winter vacation in advance, after all, the weather is really a bit cold!

The cold weather makes Lan'er, who likes to go out crazy on weekdays, is reluctant to go out again, the little girl stays at home all day long, wrapped in a thick fox fur, and is wearing cotton clothes inside, round and round, which looks even more cute!

Note that than cotton clothes, although there is cotton in the Tang Dynasty, it is just a kind of flower that is used by people as an ornament, this time has not been used to make cotton jackets, the so-called cotton robes, is made of extremely high-grade silk wool, this silk wool is also called "silk", mainly used to make cotton robes, the sentence in the "Book of Songs" "How can it be said that there is no clothes, and the son of the same robe", refers to this kind of robe.

This kind of cotton robe made of silk wadding has an excellent warmth effect, of course, counterfeiting is also quite expensive, and only the rich and noble families can afford it!

Of course, for the poor, wearing a robe with "纊" is a luxury, basically wear "缊", the so-called "缊", is a robe filled with a more low-grade silk wool, and the cold-proof effect is also very poor, even when many celebrities are unwilling, they have made bitter things about it, such as the famous Warring States period Zeng Zi, when he was unwilling, he wore this, and he rolled up his sleeves in the winter to see the elbow, and therefore contributed an idiom: stretched!

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

It is conceivable that in the era when there was no cotton, winter was a difficult thing for most people. Listen to the poems of the great poet Du Fu: The cloth has been cold like iron for many years, and the arrogant child is lying down and cracking. That is, the quilt is as cold as iron!

This is still Du Fu's house in late autumn, what is the colder and harsh winter like? I shudder to think about it.

Therefore, Li Zexuan often can't 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, you have to think of a way! ”

Lan'er pestered Li Zexuan and said pitifully, it's cold outside the house, and it's cold inside the house!

Although there is a charcoal basin at home, her brother doesn't know what is crazy, saying that the charcoal pot at home must be opened for ventilation, but in this way, it is a real ice and fire! The front is hot by the fire, and the back is cool by the wind!

At this time, she began to envy Li Zexuan for coming, don't look at this cold day, but Li Zexuan only wore a few single clothes because of his internal strength, but his big hands were always so warm, so when Lan'er saw Li Zexuan at home, she always liked to put her hand in Li Zexuan's palm to keep warm!

"Heh~! You little girl! This summer is hot and winter is a natural cycle, how can your brother have such a great ability to change the weather for you~? ”

After hearing the cute request of the little cutie, Li Zexuan was a little amused.

Lan'er blinked and said playfully, "Hee-hee! Brother can't change the sky, but there must be another way! My brother is the best! ”

"Huh! You little girl, it's still cold when you have a charcoal basin, you don't go out to see, the people outside have charcoal that the Li family can burn? ”

Mrs. Li said angrily to her daughter.

Lan'er flattened her mouth, undeniable.

Li Zexuan said happily: "If you want to talk about this method, it's not that there is no .........."

"Young Master, Fu Bo sent someone to send a stove and a batch of strange-looking briquettes, saying that they let you try it!"

An idea came to Li Zexuan's mind, when Sanbao suddenly came in from outside the door and bowed down.

"Oh~? Ha ha! Just in time! Where's the thing? Move in! ”

Li Zexuan was overjoyed and said loudly.

Since the last batch of bauxite was brought back, Fubin sent people back several batches of iron ore, sulfur ore, and coal mines! The blast furnace of the workshop has been almost built recently, so Fauber began to study how to make honeycomb coal. As for the kind of coal stove that burns honeycomb coal, the structure is not too simple, and Fu Bo directly asked his trusted craftsmen to build it!

Li Zexuan gave Fu Bo a very detailed method of making honeycomb coal, and it only took two or three days before and after, and the first batch of honeycomb coal was ready, and when he thought that he had brought an extremely practical modern item to the Tang Dynasty, how could Li Zexuan not be happy!

"Young master, it's all in the yard! The small ones are for you to move in! ”

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

The rest of the family didn't understand why Li Zexuan suddenly came to such a high level of interest, and Mrs. Ye asked with a smile: "Xiao Xuan, isn't this just a stove?" As for being so happy? ”

"Oh, grandmother, this is no ordinary stove, you'll know in a moment!"

Li Zexuan smiled and sold a pass.

After a while, Sanbao and Ah Fu worked together to move the stove and honeycomb coal in, Li Zexuan stepped forward to take a closer look, and a familiar feeling suddenly rushed to his heart. Because from the appearance, this coal stove and honeycomb coal are very similar to the ones he used in his previous life.

"Brother! Isn't this thing warm? ”

Lan'er looked at the coal stove that was almost as tall as her, and asked crisply.

Li Zexuan rubbed her little head, smiled knowingly, and said, "Hehe! Lan'er, you guessed right, but there was no reward, haha! ”

After that, he didn't care about the little girl's coquettishness, stepped forward and picked up the tongs with his own hands (this thing was available before the Three Kingdoms), clamped a piece of honeycomb coal, put it in the charcoal basin, and then he looked up and said to Mrs. Ye: "Grandmother, this thing is made of coal, I call it honeycomb coal!" You'll see in a moment how good this stuff works! ”
