Under the guidance of Jin Daqian, Li Su saw the slave maid who was digging on an uncultivated wasteland, Li Su got off the horse and went over, slightly surprised, I didn't expect this to be an open-pit coal mine, and there was a carbon layer under the soil surface, no wonder Jin Daqian found it so easily, he was ready to fight a protracted war.

The tools used by the slaves and maids are all brought back from modern times by Li Su, iron shovels, iron chisels and other tools, and now they are in full swing, with such a sharp tool, he works with a lot more efficiency.

Li Su turned around and asked Jin Daqian to build a mine in this place, the winter wheat planting had already ended, and these slaves and maids were idle, and they transformed this place into a mine, and the coal in Yizhou would be produced here.

Jin Daqian nodded again and again, and Li Su told him some precautions for mining coal mines, so as not to cause unnecessary casualties, but this coal mine adopts the method of open-pit mining, and the accident rate will be much smaller.

As he was talking, a little cold thing suddenly fell on Li Su's face, Li Su put his hand in front of him, and saw a snowflake almost melting under the temperature of his hand, he raised his head, only to see that the snowflakes were falling from the air.

"It's snowing!" Li Su's heart suddenly burst with joy, for some reason, the first snow will always make people full of infinite joy.

Jin Daqian also smiled: "It's time for snow too, and the New Year will be in half a month." ”

"So fast!" It has been a few months since he left Chang'an unconsciously, and Li Su is just living in a daze, but he didn't expect that there was still half a decade before the New Year.

"Yes, Your Highness." Jin Daqian also sighed, the prosperity of Chang'an seemed to be still in front of him, but now he was in a foreign land, he couldn't help but feel a little emotional.

Li Su stood in place and let the snowflakes fall on his body, but the snowflakes that were still falling sporadically just now turned into goose feather snow in an instant, Li Su looked at the dark sky and said, "Let's go back!" ”

The snow is getting heavier and heavier, and it is almost impossible to see the road ahead, and the group is turning over and going to Yizhou City, all saying that Ruixue is a good year, and Li Su thought that next year's wheat is expected to have a good harvest.

Galloping all the way, the group soon arrived at Yizhou City, at this time the road in Yizhou City has accumulated layers of white snowflakes, Li Su got off the horse, and said to the frozen somewhat numb hands, the winter of the Tang Dynasty is not the modern winter that is plagued by the greenhouse effect, the temperature is more than ten degrees below zero, this is why there is a road with frozen bones, basically at this time, the people are nested at home and rarely go out, such a cold day will freeze to death.

Shrinking his neck and returning to the south courtyard, Li Su only felt a little warmer when he entered the house, Cui Yingying sat in front of the charcoal basin in thick clothes to roast the fire, Tong Nian just came a few days ago, the temperature in Yizhou dropped sharply, and fortunately at this time, he sent the coal over, otherwise these few days would be enough for Li Su.

"Your Highness, come and bake the fire." Cui Yingying saw Li Su come in, beckoned, after the temperature cooled, Li Su asked Jin Daqian to transport the three carriages of carbon back to the palace for storage, this winter can count on them to keep warm.

Li Su's ears and nose were blown a little numb by the cold wind, he sat next to the charcoal basin, and quickly rubbed these frozen numb places, Cui Yingying on the side saw it and said, "Your Highness, why do you go out so cold!" Look at the one that froze. When he spoke, he used his hand to help Li Su warm his ears.

"I just went to see the Carboniferous Mine." Li Su said, while looking at the heavy snow outside.

Cui Yingying understood, "Fortunately, I brought some charcoal from Chang'an, otherwise, I really don't know how to spend this winter." ”

"Therefore, we must quickly excavate this coal mine, and strive to use the coal for the people of Yizhou next winter." Li Su said when he took a look at the clothes that Cui Yingying was wearing outside, they were made of pure mink, and when he came back just now, he also paid attention to the people on the road, they didn't have such good clothes to wear, at most they had a few more clothes, there was no cotton in the Tang Dynasty, and naturally there were no cotton jackets, and this winter passed, it seems that there are really a lot of things to plant.

The two were roasting the fire, gossiping, a gust of wind poured in through the window, the biting cold made both of them shiver, Cui Yingying said to Xiao Cui who was standing next to him: "Xiao Cui quickly close the door and leave a window." ”

In Chang'an, it is normal to use charcoal for heating, and Cui Yingying also knows how to pay attention to ventilation when burning these coals, because every year in Chang'an, there are several people who lose their lives because of improper use of coal.

Thinking of this, Li Su said: "Xiaocui, you go and remind me that you must leave a window when you use charcoal to bake fire." ”

"Yes, Your Highness." After speaking, Xiaocui trotted out of the south courtyard and went to the north courtyard.

Cui Yingying glanced at Xiao Cui who was leaving, and leaned on Li Su, "Your Highness, there is still half a decade before Yuanzheng, and the palace should also prepare." ”

Li Su was a little interested, after all, it was the first time to spend the New Year in the Tang Dynasty, and according to the customs of the Tang Dynasty, court officials had seven days of holidays during the New Year, and these seven days could be fun.

"Well, it's time to prepare, this New Year's goods have to be prepared, let Jin Daqian prepare more meat, venison, horse meat, beef, etc., the people have been busy for so long, and they will also be satisfied." Li Su said.

Cui Yingying's eyes lit up with excitement, "There are also flags, I have to let them prepare, and buy some rubber tooth dumplings back." ”

On the morning of the first day of the Tang Dynasty, a bamboo pole was inserted on the ground, and a long flag-like thing was placed on the top of the pole, this thing was called a flag, and the gum tooth is maltose, this sugar is actually a dessert made of wheat, soft and sticky, and the sweetness is not high, but it is a snack that people in the Tang Dynasty like to eat.

Li Su was only busy with machinery and tools last time, but he forgot about this, he said: "I'll get you some delicious food during the New Year." ”

"Really?" Cui Yingying said excitedly, speaking of which Cui Yingying is just a big girl, she is still very greedy, Li Yu said with a smile: "Let you eat enough when the time comes." ”

The next day, Li Su got up early, he liked the heavy snow, a silvery world, opened the door, Li Su involuntarily shrank his body, today is a little colder than yesterday, the snow outside has not stopped, but it is a lot smaller.

There was already a thick layer of snow in front of the house, Li Su stepped down, "squeak", the snow directly passed his feet to his calves, the trees in the yard, at this time a thick layer of snow was hanging, the branches were bent, Li Su kicked out of the south courtyard one by one, Jin Daqian was leading a few maids with brooms to this side, saw Li Su come out, and said: "Your Highness, why did you get up so early, I was looking for someone to clean the yard for you." ”

"I can't sleep and get up, you just let them clean up now, I'll just walk around." Li Su said and walked to the outside of the Shu Palace.

Jin Daqian answered and commanded the maid to enter the South Courtyard, while he was busy directing his subordinates to clean up the snow.

Let the courtyard open the door, Li Su's eyes immediately appeared a world covered in silver, the palace stood on the street, he stretched his head and looked, there was nothing on the street except thick snow, not even the footprints of a pedestrian, and the endless buildings were covered with a layer of white ice and snow, and the whole world looked clean and intoxicating.

Standing at the door for a while, Li Su walked towards the North Courtyard, Su Xiaoyan now lives in the North Courtyard and is taken care of by several maidservants, Su Mo'er also handed her over to her own care, and she also has to have snacks.

Compared with the south courtyard, the north courtyard is much more lively, the family and maids are all shuttling back and forth, each busy with their own affairs, seeing Li Su is constantly saluting, Li Su nodded and walked towards Su Xiaoyan's room.

"Ahh

Li Su was walking, a scream suddenly sounded, Li Su turned to the direction where the sound came from, only to see an object go straight to the door, one of his dodges was hit squarely, and then his face was cold, but it was a snowball.

Li Su wiped the snow off his face, looked at the culprit who threw the snowball, didn't think it was Su Xiaoyan, this girl was excited, but after seeing the snowball thrown on Li Su's face, her smile suddenly froze, of course Su Mo'er told her Li Su's identity, although she was only ten years old, there were some things she already understood.

Li Su didn't care, wouldn't it be too wasteful not to have a snowball fight with such a big snow, he threw a snowball over, but the line was too poor and it was missed.

The little girl smiled again when she saw it, knowing that Li Su didn't blame him, but playing with her, she laughed and grabbed a handful of snow, turned it into a snowball and threw it at Li Su.

Li Su had the intention to make her happy, a dodge, and re-set up a snowball to chase her, the little girl had a smile on her face, hiding among the people, throwing a few snowballs from time to time to fight back, Li Su didn't hit her a few times, she was smashed by the little girl several times, and Su Xiaoyan made trouble for a while, Li Su thought that Cui Yingying should also get up, scratched the little girl's nose and walked to the south courtyard, and was thrown by the little girl before leaving, it seems that she still hasn't played enough, Li Su said to a few maidservants: "You just play with her, There is no need to be courteous. ”

The maidservants looked at each other, their eyes showed excitement, they were all fifteen or sixteen years old, and they were also greedy for fun, so they started playing with the little girl while talking.

Li Su returned to the room, Cui Yingying had already gotten up, Xiaocui was waiting for her to get dressed, she saw that Li Su was covered with snow, and said with a smile: "Your Highness, why don't you call me when you go to throw snowballs!" ”

"You slept so soundly, how could I be willing to disturb you, and now I'm not back? How about I build a snowman and catch sparrows later? Li Su smiled, such a big snow can't do anything, what else can you do except play.

"Catch sparrows?" Cui Yingying wondered, "How to catch it?" ”

Li Su smiled mysteriously: "You'll know later." ”
