Li Chengqian really caught a cold, and shivered coldly with a circle of fur, trying to find a quilt, and found that cotton was only an ornamental plant in Datang, and the quilt only existed in his ideals.

When I came back from Comrade Lao Li three days ago, I thought about whether to pretend to be sick, but I said it casually, but I didn't expect it to become a prophecy, and I really caught a cold.

So Li Chengqian regrets it now, while secretly scolding himself for his crow's mouth, he held a big bowl of medicine prescribed by the imperial doctor, and swallowed it with difficulty, not because it was too bitter, but because he really couldn't drink it. From morning to noon, I didn't eat a bite of food, and the medicine had been poured into 6 bowls, and my stomach was round and unpleasant, and I was very hungry.

And the weather is too cold, in the dormitory to do 4 charcoal basins are not a big thing, in addition to the room is not frozen, not much better than the outside.

"His Royal Highness the Prince, the blacksmith has returned, just waiting outside the door, can you see it?" After opening the door and saying a few words to the guards outside, Chunxiao walked back with a cold air and said to Li Chengqian.

"The blacksmith is back? Let him in, come in. "Looking forward to the stars, looking forward to the moon, it can be regarded as looking forward to this master.

The pattern of the furnace has been drawn for two days, but the blacksmith in the palace took his mother-in-law home to save his relatives, and he never came back, so he could only put the picture there and look at Chunxiao with wide eyes.

"Your Highness, Xiaomin went home to save his relatives, and he came back late, and I hope His Highness will forgive his sins." The blacksmith came in with a cold body and gave Li Chengqian a salute, and then shuddered and pleaded guilty.

It's not scary, it's just frozen outside.

The Tang Dynasty did not have cotton clothes and cotton pants, and the main clothes of the people in winter were cotton clothes. The cotton clothes are different from the current cotton clothes, cotton refers to the pieces or balls formed by silk, and this thing is stuffed into the mezzanine of the clothes to become cotton clothes.

How to say this kind of thing, if you want to say that it can keep out the cold, it must have this function, but if you want to say that this thing can keep warm, it seems to be a bit of nonsense.

"It's free, you can understand the picture in her hand." Li Chengqian was blown by the cold air brought in by the blacksmith, and the spirit shivered, and the fur was wrapped tighter, and then pointed to the picture of the stove in Chunxiao's hand.

"Let's take a look." The blacksmith continued to tremble, took a few pieces of paper from Chunxiao, and looked at them carefully.

"You'd better put it on the table and watch it." Li Chengqian looked at the blacksmith's shaking hands like sifting chaff, and his eyes jumped, can he see this clearly.

"Yes, yes." The blacksmith put the picture on the table, looked at it carefully for a while, then turned his head and said, "Your Highness, the picture Xiaomin looks at it, but the words written on it, Xiaomin don't understand." ”

"Words?!" Li Chengqian frowned and thought for a while, and suddenly reacted, the size of the picture was all written in Arabic numerals, and no one in the entire Tang Dynasty seemed to know him except for Chunxiao and himself, who had just learned.

However, what Li Chengqian admires most is the blacksmith's ability to read pictures, and the stove on the paper is drawn like a chicken planer, which is not round or square, nor is it square. The straight line is like a wave line, the arc is like a sinusoidal curve, just like this, the blacksmith can understand it, I have to say that the Datang craftsmen are really awesome.

It took more than ten minutes for the blacksmith to figure out the meaning of the numbers, which meant the use of the numbers, not the understanding.

"Your Highness, Xiaomin has already seen it, this object Xiaomin can do." After such a long time, the blacksmith finally recovered a little, it was not so cold, and he spoke much more smoothly.

"It's good if you can do it, it's good if you can do it." Hearing the blacksmith confidently say that he could do it, Li Chengqian felt that the cold on his body was a little weaker, and he finally had to say goodbye to this kind of life like a cold bird.

"But, not ......." The blacksmith's eyes flickered, and he stopped talking, and he stammered for a long time without saying why.

"But what, hurry up." Li Chengqian couldn't stand the cowering appearance of these craftsmen, he could say whatever he wanted, could the master still be able to cut people? Even if the master wants to cut it, the emperor will not agree.

"Xiaomin just wants to ask His Highness, you~, can Xiaomin use Arabic numerals in the future?" The blacksmith hesitated for a long time, but finally asked what he wanted to ask.

"I'm ......." Li Chengqian, who had been nervous for a long time, let out a big sigh, thinking that the blacksmith could say something difficult, but this was the result.

"No problem, you can use it, and you can teach it to your students if necessary." Looking at the blacksmith's eyes, Li Chengqian knew that if he didn't give him a clear answer, he was afraid that this old boy would not be at ease.

"Your Highness......." Chunxiao was stunned by Li Chengqian, and never thought that he would pass on the numbers so easily, and even to a craftsman.

Li Chengqian didn't let Chunxiao finish her words, waved his little hand to stop her next words, and said to the blacksmith: "Go, make the things that this king asks, it's better to do more, I'm afraid there are many places in this palace that can be used." ”

The blacksmith who received an affirmative answer smiled and left, His Royal Highness the Crown Prince was very kind, and also taught a simple counting method, which can be used as a family heirloom when taken back.

Chunxiao took the medicine bowl in Li Chengqian's hand and said to him with some complaints: "Your Highness, why did you agree to him so easily?" You must know that these words are very important, and even if you go to a private school, you don't necessarily teach them. ”

Chunxiao is the daughter of a former Sui offender, and she entered the Teaching Department at a very young age, and later entered the palace as a palace maid because of her sweet appearance, so she knew that even a private school outside could not teach Arabic numerals.

"Words were invented to be used, if they are all swept away and cherished, I'm afraid that we are still eating raw meat and drinking raw water, so don't care." Looking at the puffing Chunxiao, Li Chengqian thought of his sister and slowly reasoned with her and explained her.

Although Li Chengqian is only 8 years old now, he has a soul from the future in his body, and no one understands the importance of opening up the people's wisdom better than him. Only when the living standards of the entire Tang people are generally improved, will the life of the people of the Tang Dynasty be meaningful, otherwise in an era of lack of food and clothing, even if you want to, you can't get up.

"Hmph, Your Highness is just too good at talking, and any craftsman can put forward conditions." Chunxiao was very unimpressed by Li Chengqian's words, and was still sulking.

"Okay, okay, let's not talk about it." It may be that the medicine that he just drank in his stomach finally took effect, Li Chengqian felt that his body was not so cold, so he loosened his fur fur a little, and seemed to think of something, so he turned his head and asked Chunxiao: "Is there any news about the white stack you said yesterday?" Is there anything in the palace? ”

"The slave asked the steward, and said that there seemed to be some in Curry, but it was not clear how many there were, and there should be news in a while." The little girl's depression came and went quickly, and when it came to Bai Diezi, Chunxiao almost immediately forgot about the blacksmith just now, and began to talk about Bai Diezi's cuteness.
