ps: Lao Yu made a big oolong yesterday, the nine thousand urging is going to be more today, the old fish has a hot brain, and he gave it nine thousand yesterday, but it doesn't matter, even if it broke out yesterday, today it was hard to code out two chapters of six thousand words, nine thousand words are unlikely, and there is another one thousand or two thousand urgings, which makes the old fish even more out of reach, I'm really embarrassed. This is the first chapter, the second chapter before nine o'clock.

It was difficult to leave the palace once, Li Shimin's interest was very high, and he stayed in the cold drink shop until noon. This cold drink shop is very cool because of the ice-making shop, and it is a good place to escape the heat. Qinghe played with Gao Yang and Xue Yan all morning, and they were all a little tired, and their sons were already asleep, Li Shimin was heartbroken for his daughter, and let people send Qinghe and their 65th chapter Li Shimin to the mine The three of them were sent back to the palace first, but Li Su and Li Zhi were left.

"Uncle, the snow goose is also tired, the little nephew will say goodbye first and send the little sister back to the house to rest." Li Jingheng was very slippery, and when he saw Li Shimin leaving his two sons behind, he guessed that he might have something to say, so he was ready to slip away.

"Well, when the snow goose is tired, let people send her back first, and you will stay too!" Li Shimin glanced at the little fat man and said lightly.

Li Jingheng had no choice but to comply, and at the same time he also complained a little about Li Su in his heart, and he kindly invited him to come and sit together, but he didn't expect to invite Li Shimin, the great god, and now even he has been arrested, although he doesn't know what to do with them, but in his intuition, there must be nothing good.

"Rokuro, I heard that you opened a few coal mines outside the city?" After sending the little girls away, Li Shimin suddenly turned his head to Li Su and asked.

Li Su was stunned, I don't know why Li Shimin suddenly asked this question, but Li Jingheng next to him was moved, and there was a little panic on his face, but unfortunately Li Su didn't see it, but just replied honestly: "Father Qi, the son did open a few coal mines, because the charcoal can be used as fuel for burning cement, than the charcoal that Li Shimin wants to go to the mine in Chapter 65 not only burns longer, but also cheaper, and even the waste residue after burning can be used for road repair." ”

"Well, you're a cement overseer." Li Shimin said lightly after hearing this, the expression on his face was very calm, "I'm very interested in your carboniferous mine, you can take me to have a look!" ”

"Now?" Li Su asked in surprise, it's noon, the sun outside is very poisonous, what is crazy about the emperor's father, he wants to go so far to see the carboniferous mine?

"Liulang, I also want to know how your carboniferous mine works, after all, we are also preparing to open a carboniferous mine, it just so happens that my uncle is also interested, why don't you take us to see it, and let my brother learn two tricks!" At this time, Li Jingheng also said suddenly, and while speaking, he glanced at Li Xuan, and he didn't know what he meant?

Li Su felt that there seemed to be something strange in this, but he couldn't guess it for a while, and looking at Li Shimin's appearance, it seemed that he had made up his mind to go to the coal mine, coupled with Li Jingheng's strange behavior, so Li Su could only agree.

Seeing that Li Su agreed, Li Shimin immediately got up, and the group went downstairs to get into the carriage, and began to drive away to the Black Stone Mountain outside Chang'an City, there are several coal mines, but it is the closest here, and it is only about twenty miles away from Chang'an, the speed of the carriage is extremely fast, and the guards brought by them are also riding horses, so it is only half an hour, and they came to Black Stone Mountain.

The road in Heishi Mountain is not easy to walk, Li Su has already asked people to use cement to build a road from Chang'an to here, but it has not been repaired yet, now the road is simply paved with cinders and crushed coal, and the carriage of Datang has no shock absorber, so this road almost vomited out Li Suan, plus the weather is hot, although the windows on both sides of the carriage are opened, but the hot wind blows in, and the sweat on the body is also layer by layer, even if it is drinking herbal tea.

When they finally got out of the car, Li Su and Li Zhi's faces were not very good-looking, Li Jingheng was even more miserable, he was obese and his whole body was soaked with sweat, and the exposed skin was also red, looking as if it had been roasted. However, Li Shimin's face was as usual, except for a slight sweat stain on his forehead, he didn't see anything unusual at all.

Heishi Mountain and the surrounding radius of dozens of miles were bought by Li Su, forbidden outsiders to enter, here is the largest of several coal mines, sent here the palace soldiers and Tubo prisoners of war are also the most, of which there are about 200 personal soldiers, and there are more than 1,000 prisoners of war.

As soon as Li Su and the others approached the coal mine, they were immediately stopped by the recruits in charge of guarding, and when they saw that it was Li Su in the car, they immediately let them go, and sent someone to inform the Dianjun.

Li Su accompanied Li Shimin to park the carriage in a flat square at the bottom of the mountain, which was covered with many brick and cement houses on one side, which was the residence of the royal soldiers, and behind this row of houses, there were some work sheds made of wood and thatch, in which the Tibetan prisoners of war lived.

And in the center of this square is piled up of freshly mined coal, forming a small coal mountain, some special carriages are loading coal next to it, these charcoal is to be transported to the various cement factories in Chang'an, the carriage is provided by Wang Zihao's car dealership, specially used to transport coal, the huge profits of coal mining Li Su occupied, but the surrounding related industries were handed over to Wang Zihao, although the profits are not as good as the coal, but also very considerable.

On the mined deposits in the mountains, countless tattered-clad Tibetan slaves were toiling under the whip of the overseers, and these slaves worked in groups of ten, all with iron shackles on their feet, wielding pickaxes to mine large pieces of coal, and then put them on a special cart and transport them to the main square where Li Su was located.

"Father, please see, this is the Black Stone Mountain, the mountain and the surrounding radius of dozens of miles are coal, the mining cost is very low, but in order to further reduce the cost, Erchen bought a lot of Tibetan prisoners of war as coolies." Li Su jumped out of the carriage with Li Shimin, pointed to the busy scene in front of him and said.

Li Shimin looked around at the surrounding scene, nodded with some satisfaction, and showed a little smile on his face, and walked to the small coal mountain in the middle of the square with great interest, watching the loaders throw a piece of charcoal on the car.

The work on the coal mine was not all done by the Tibetan slaves, they were only responsible for the hardest and most tiring work of coal mining, in addition, such as transporting the charcoal to the square and loading the trucks, and some cooking, boiling water, sewing and mending and other work, all of which were done by hiring the poor people around them, which was regarded as Li Su's compensation for them after occupying the Black Stone Mountain, after all, after he bought this place, these poor people could not take charcoal for heating in winter, and Li Su's wages for them were relatively rich, enough to feed a few people.

At this time, two loaders, an old man and a young man, finally filled a car, and now it was noon, both of them were hot and sweaty, and their dark skin was covered with black soot, which was soaked by sweat, forming a layer of black sludge, which looked very dirty.

The young and old couple were about to take a break, walked to the side of the pool, scooped up a towel of unknown color, wrung it out and wiped it on their faces and bodies, not for cleaning, but just to cool down by the evaporation of water, and then rushed to a simple pergola on the right side of the pool, scooped out a bowl of water from a large bucket and poured it down.

Li Shimin walked to the pergola and greeted the forty or fifty-year-old man: "This old brother is invited, can I have free time now, I have something I want to talk to my brother?" ”

"Yo! The nobles are very polite! As soon as the old man saw Li Shimin's bearing and dress, he immediately knew that the other party was not a mortal, so he said very respectfully, "I don't know what is the matter with your nobles?" The old man had just finished loading the car and was about to take a break before doing things. ”

"Hehe, it's actually not a big deal, I just want to talk to my brother about family life." Li Shimin smiled, and then asked, "I don't know what to call my brother, this year's Gui Geng, what did you make a living before?" ”

After the old man asked Li Shimin to sit down, he replied: "Oh, the old man's name is Zhang Dashan, he is just fifty years old this year, he used to live next to this black stone mountain, guarding a few acres of thin fields at home, and eating the last meal without the next meal, fortunately, someone took a fancy to this place and opened this carboniferous mine, so that my grandson and I were able to find a place to live here, and the family was much richer." The old man said and pointed to the seventeen or eighteen-year-old boy, probably because of malnutrition, although the boy was seventeen or eighteen years old, he was not yet fourteen years old, Li Su looked tall and strong.

"Oh? You're so old, why don't you let your son come to work? Li Shimin asked strangely.

"Alas, speaking of this, the old man I feel uncomfortable, in fact, we are not Chang'an people, because a few years ago I fled the famine and came here, my son and daughter-in-law were separated on the road, only this one grandson followed me, the government here is not bad to us, and we have allocated some fields to our grandchildren, but because there are many people around Chang'an, the prescribed mouth can only divide the fields so little, and the little food that comes out of the field every year is not enough to eat, and the old man does odd jobs everywhere to raise his grandson so big, but he is seventeen years old this year, but he didn't even say a daughter-in-law." When the old man talked about the sad things, he couldn't help but shed tears, but the young man beside him opened his mouth to comfort his grandfather.

"Brother mourning, didn't you just say that the family is much richer, and when you save some money in the future, you will tell your grandson about the daughter-in-law, and you and your son are just separated, maybe there will be a day when we meet, so you must look away." Li Shimin didn't expect the old man in front of him to have such a bumpy experience, so he could only open his mouth to comfort.

"The noble man said that the owner of this mine is generous, and the salary is higher than that of other places, and after a period of time to save enough money, the old man will tell his grandson that he is a daughter-in-law, but the old man is rude for a while, so that the noble man laughs." The old man suddenly came to his senses, after all, the other party was a stranger, and it was really a very rude thing to lose his temper in front of others, so he hurriedly wiped away his tears and smiled. Li Shimin didn't mind at all, and said with a smile that it was okay.

Li Su and Li Zhi were waiting outside, not daring to disturb Li Shimin's interest, but Li Jingheng kept complaining to Li Su, saying that he shouldn't have taken Li Shimin to the cold drink shop, and as a result, he also suffered from this unwarranted disaster, and ran to this mine on a hot day to suffer. Li Su is also very aggrieved, he was also caught by the emperor's father, and he was also victimized when he said it, besides, where does the emperor's father want to go, how can he, a son, stop him?!!!
