Otaku Engineer in Great Tang Dynasty

Cui Shanyou was "entrusted with a heavy responsibility" by Li Er and sent to Hongwenguan to study history. The supervising students of the Imperial College did not dare to make trouble anymore. For this reason, the Zheng family of Xingyang sent people to warn Zheng Huaibo and let him be honest.

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

Such a Li Zexuan, the Zheng family is still unwilling to provoke, it can not be said that the Zheng family is afraid, but they do not have much grievances with Li Zexuan, it is not worth to the point where the fish die and the net is broken!

Aristocratic families are all profitable!

The days suddenly became leisurely. After several days, no one came to harass Li Zexuan.

As the New Year approaches, the weather is getting colder and colder. Although it has not snowed yet, Chang'an is located in northern China. In winter, the north wind often whistles, and the wind blows on the face like a knife. Li Zexuan has been wondering whether or not to let the college students have winter vacation in advance, after all, the weather is really a bit cold!

The cold weather made Lan'er, who likes going out crazy on weekdays, reluctant to go out again. The little girl stayed at home all day long, wrapped in thick fox fur, and she was still wearing cotton clothes. lovely!

Note that cotton clothes are not cotton clothes. Although there was cotton in the Tang Dynasty, it was only used as a kind of flower for viewing. At this time, it was not used as a cotton jacket. The so-called cotton robe was used. It is made of extremely high-end silk floss. This silk floss is also called "纩", which is mainly used to make cotton robe. The phrase "Qi said no clothes, go with the child" in the "Book of Songs" refers to this kind of robe .

This kind of cotton robe made of silk flock has excellent thermal insulation effect. Of course, counterfeiting is also quite expensive, and only a rich family can afford it!

Of course, for the poor, it is a luxury to wear robes with "纩". Basically, they wear "缊". The so-called "缊" is a robes filled with a lower-grade silk floss. The effect is also extremely cold. Poor, even many celebrities made trouble for this when they were unwilling. For example, Zeng Zi, a famous writer in the Warring States Period, wore this when he was unwilling. In the winter, he would see his elbows when he rolled up his sleeves.

Of course, in addition to silk material, animal fur clothes are also necessary to keep out the cold, but high-end fur clothes are basically patented by the rich and nobles. Of course, ordinary people can't count on it.

It is conceivable that in the era without cotton, winter was such a difficult thing for most people. Listening to the poem of the great poet Du Fu, you know: The cloth quilt has been cold like iron for many years, and the arrogant and evil are lying and cracking. That is, the quilts are as cold as iron!

This is Du Fu's house in the late autumn, what is the colder winter? I have to shiver when I think about it.

Therefore, Li Zexuan often couldn'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 is so cold, you must think of a way!"

Lan'er entangled Li Zexuan and said pitifully, it was cold outside, and it was cold inside!

Although there is a charcoal basin at home, her brother didn't know what was going crazy. He said that the charcoal basin at home must be opened for ventilation, but in this way, it will be a real double sky! The front is hot by the fire, and the back is cold by the 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 Lan'er saw him. Li Zexuan always likes to put his hand in Li Zexuan's palm to keep warm at home!

"Heh~! You little girl! The hot summer and cool winter are natural cycles. How can your brother have such great ability to change the weather for you~?"

Li Zexuan said a little amused after hearing this lovely request from Xiao cutie.

Lan'er blinked and said playfully: "Hehe! Brother can't change the sky, but there must be other ways! Brother is the best!"

"Heh! You little girl, there is a charcoal grill and it is cold. You don't want to go out and see, there are people outside that Li family can burn charcoal?"

Mrs. Li said to her daughter irritably.

Lan'er flattened her mouth and couldn't comment.

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

"Master, Fubo sent someone to send a stove, and a batch of strange-looking briquettes, and said he wanted you to try it!"

There was an idea in Li Zexuan's mind, Sambo suddenly came in from the door and bowed.

"Oh~? Haha! It just happened! Where are the things! Move in!"

Li Zexuan said loudly with joy.

Since returning a batch of bauxite ore last time, Fubin has sent back several batches of iron ore, sulphur ore, and coal! The blast furnace in the workshop was almost built recently, so Fober began to study how to make briquettes. As for the kind of coal stove that burns briquettes, the structure should not be too simple~www.ltnovel.com~Fuber directly let his trusted craftsmen build it!

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

"Master, they are all in the yard! The younger one will move in for you!"

Seeing that his young master was happy, and Sambo was also happy, he responded with a grin.

Others in the family didn't understand why Li Zexuan suddenly came so excited. Old lady Ye smiled and asked, "Xiao Xuan, isn't this just a stove? As for you so happy?"

"Hehe, grandma, this is not an ordinary stove, you'll know in a while!"

Li Zexuan smiled and sold it.

After a short while, Sambo and Ah Fu moved in both the stove and the briquettes. Li Zexuan stepped forward and took a closer look. A familiar feeling immediately came to mind. Because from the appearance, this coal stove and briquettes are very similar to those used in his previous home.

"Brother! Can this thing make people warm!"

Lan'er looked at the coal stove that was about to have her, and asked crisply.

Li Zexuan rubbed her little head and said with a knowing smile: "Haha! Lan'er, you guessed it right, but there is no reward, haha!"

After all, he didn't care whether the little girl was acting like a baby. He stepped forward and picked up the tongs (this thing existed before the Three Kingdoms), clamped a piece of honeycomb coal, put it in the charcoal basin, and then raised his head and said to Mrs. Ye: " Grandma, this thing is made of coal. I call it briquettes! You will know the magical effect of this thing in a moment!"
