The weather at the end of May, even the wind seems to be carrying sweat, and the blowing on people does not feel cool at all, but makes people even more upset.

Duan Yunjie stood under a banyan tree on the slope, watching Shen Chengrong come out of the door of Xu Ping's residence, two personal servants waiting for him to get on the horse, he drank a little too much, and it was not easy to climb up crookedly.

One of the servants watched the road ahead, while the other led the horse down the hill.

Constantly burping, Shin Seung-young only felt satisfied. Who says it's no good to be honest? If it weren't for his honesty and obedience, Xu Tong would have promoted him? Although the name of the mountain sounds a bit low-level, it is also at the same level as Tuxian, and then the place of care, his Zhitong is bigger than many Zhizhou. As for the official position rewarded by the imperial court, it is a false name, and he is not given a good fortune, and he can be promoted again if he does a good job.

Shook to the foot of the mountain, but Shen Chengrong felt weird, from the moment he went out, he felt that there was something special, worried about his heart, and there was obviously nothing.

The slanted sunset dangled on Shen Chengrong's eyes, making him a little confused, and he involuntarily turned his head to avoid the dazzling sun.

The moment he turned his head, he saw a slender figure standing under the banyan tree in the middle of the slope, quietly looking at him. This is the first time he has seen a person, his face is so strange, but so familiar, as if he is far away in the world, but he has always been by his side.

Shen Chengrong's eyes were a little flowery, and two old tears poured out involuntarily.

"Lord, what's wrong?"

The servant who led the horse saw Shen Chengrong's body shaking on the horse, and hurriedly asked.

Shen Chengrong shook his head vigorously, stabilized his body, and waved his hand: "It's okay, it's okay, let's go, it's getting late." Let's hurry home, go home-"

Looking at the gray sun in the distance, two tears still flowed disobediently.

What parent doesn't love smart kids? That daughter was also his heart, and he sincerely hoped that the child could live happily for the rest of his life. It is fate to give the Huang family since childhood, and the children of the chief have been married to each other like this for many years, and no one can escape. When the child is older, he will find a wishful man, he has never said anything about children, the barbarians do not pay as much attention to the relationship between men and women as the Han people in the Central Plains, as long as the child is happy, and a young official is also considered to be their family. Who would have thought that so many things would happen later? He is a barbarian little mountain master, he can't afford to provoke either side, he is not alone, there are hundreds of families in the whole mountain, how dare he let his temperament mess around? Today, he can use him to beat Zhongzhou, and he can use Zhongzhou or Wuli County to clean him up back then, and he can only forget about that kid ruthlessly.

However, there are some things that cannot be forgotten after all.

Duan Yunjie watched Shen Chengrong's figure disappear into the bamboo forest and barren grass, turned around silently, and walked towards his residence. My mother used to hold and raise herself, but for as long as she could remember, she had never seen her again, and she didn't even remember what she looked like at all. Everyone said that they were similar to their mothers, but they still couldn't imagine what that woman looked like.

What kind of woman is that? can make my father wait silently for more than ten years, desperate, waiting for the day of reunion in the future.

Duan Yunjie didn't know if he had disappointed himself when he saw Shen Chengrong, he only knew that after seeing this side, his heart was completely calm. He is a child without a mother, dependent on his father.

Xiuxiu and Liu Xiaomei sat side by side by the pond next to the bamboo forest, sticking their bare feet into the water, gossiping endlessly, and the fruit dismounted not far away slowly wandered and graze.

Seeing Duan Yunjie hurriedly walking over with her head down, Xiuxiu said, "Sister Duan, where have you been?" Just now, the official asked about talking to you! ”

Duan Yunjie's thoughts were interrupted, and she raised her head and asked, "Oh, ask me what?" ”

"How do I know? The officials don't tell me anything about it! ”

Xiuxiu tilted her head to look at Duan Yunjie, seeing that his expression was a little dazed, and then said, "Sister Duan, your face is a little unsightly, are you sick?" ”

Duan Yunjie smiled reluctantly: "No, maybe I was in a hurry just now." Then you guys continue to play here, and I'll go to the officials and see what's going on. ”

Watching Duan Yunjie leave, Xiuxiu shook her head at Liu Xiaomei beside her: "Weird! ”

Entering the door, Xu Ping was sitting in the shade of the courtyard, Duan Yunjie cheered up and stepped forward to salute: "Listen to Xiuxiu, the official has something to ask me?" ”

Xu Ping didn't pay attention to Duan Yunjie's demeanor, and said casually: "It's nothing, it's just that you have used a lot of paper there recently, and I want to ask what kind of books are printed, and I haven't seen businessmen from other places coming." ”

"That's what happened. Recently, most of the "Tang Poems" and "Anthologies" have been printed, and they are not sold to guests from other places, but are bought by new Fujian guests. ”

"Oh, they buy books?"

Xu Ping sat up straight in surprise and looked at Duan Yunjie.

Duan Yunjie smiled: "But isn't it, I didn't expect that there are many literate people among them." ”

"Oh, I see, interesting." Xu Ping leaned back in his chair, pondered for a while, raised his head and found that Duan Yunjie was still standing there, a little embarrassed, "A little thing, let you come." - You go about your business, there's nothing else to do. ”

Fujian Road since the time of Fujian Yue Qian family on the development of culture and education, and the next Jiangxi is the most developed area of the Song Dynasty culture, there are a lot of readers, so that the difficulty of the solution test in some states is not less than the provincial test palace test.

Xu Ping forgot about this, because before the Fujian immigrants came, it was difficult for the hundreds of local peasant households gathered together to find a few who could read and write, and some of them could not speak Chinese, and the promotion of various technologies took a lot of work. I didn't expect that as soon as these Fujian people came, there were so many readers that the number of books printed could increase significantly, which was an unexpected joy, and in many cases, the role of readers was really irreplaceable.

After thinking for a while, Xu Ping called Tan Hu and told him to go to Duan Fang, as well as Gao Daquan and Huang Tianbiao, and call the little leaders of the immigrants to his courtyard at night, and he had something to talk to them.

When the immigrants arrived just in time for the busy farming, Xu Ping didn't dare to toss for fear of delaying the farming, but they just let them roughly divide into groups, and Duan Fang and Huang Tianbiao led the county officials to take them busy. Now that the season has passed, the rice has been planted, and the sugarcane is planted while the ground is opened, anyway, the planting is a little later but the amount of sugar is less, and it is more convenient to plant it when it is opened.

The sky gradually darkened, Xiuxiu bent down at the door to look at the seven or eight lamps on the table, and asked Xu Ping curiously: "Official, what kind of lamp is this?" It's so bright! ”

Xu Ping said: "This is a horse lantern. ”

Xiuxiu pouted: "It's a lie again, this is obviously an oil lamp!" ”

"You say it's an oil lamp, it's an oil lamp."

"Official, what kind of oil is used in this? How is there no smoke? ”

"It's called kerosene, and of course there's no smoke when it's light."

"Why is there no smoke when the oil is light? And what does kerosene come from? ”

"Of course, kerosene comes from coal, not squeezed out, but steamed. Xiuxiu: I'm very busy tonight, don't you ask here, can you ask again when you have time? ”

"I'm not uncommon to ask! By the way, this cover - forget it, I'll play with Liu Xiaomei! ”

Seeing a large group of people coming in outside, Xiuxiu ran into the backyard angrily, she also wanted to ask what was going on with the transparent cover, the official clearly said that the glass was made to make her the brightest mirror.

In this era, transparent glass was already available, but there were very few transparent glass products, and most of them came from overseas, and they contained expensive rose water and other expensive things for women. The Han people are accustomed to using ceramics, and there is no motivation for the development of glass products, and they cannot pass off as jade like the previous generations, so they are even less interested. However, transparent glass bottles from overseas are still very precious, and some people will deliberately collect them.

In the past, Xu Ping didn't have the motivation to burn glass, he couldn't eat or wear, and he didn't expect this to make money for himself, Zhongmu's huge grange was no longer able to eat and spend. Until a few days ago, coke was made from nearby coal, and although there was a lot of coal here, the quality was not good, and it could not be used to make iron, so it could only be used to make steel at a lower temperature, which was better than charcoal. In this way, the process of charcoal refining was accompanied by a large amount of coal tar, and Xu Ping distilled the coal tar on a whim, and actually made kerosene. In fact, the reason why kerosene in his previous life was called kerosene is because it was first distilled from coal, but within a few years of the emergence of this technology, it became popular to make kerosene from oil, leaving only a few traces in the name.

The technical route involved in the use of oil is too complicated, and Xu Ping really can't afford to play that spirit, but making kerosene from coal is much simpler, and it can be made with a little in the process of coking, and Xu Ping will not let go of this kind of good thing.

Of course, kerosene lamps should be made with kerosene, and the part that holds the oil can be made of porcelain, and the lamp mouth just made tinplate a few days ago, which is just right. But in order to prevent the wind, a transparent lampshade is indispensable, and it would be a pity to have a kerosene lamp and use a papier-mâché cover like before, Xu Ping turned his head and burned the glass again.

There are many rivers in the vicinity, and the Yujiang River produces good quality glass sand, and there are also miscanthus nitrates and limestone here, which are all materials for clarifying glass. Xu Ping also knows that adding lead to glass can improve transparency, such as lead ore in He County, all the materials are ready, and transparent glass can be made little by little.

Today is the first official use of kerosene lamps, Xiuxiu was a little unhappy when she saw it, there were any novelties Xu Ping gave her first, this time there are so many outside, she hasn't used it yet. Lying here pestering Xu Ping to ask questions is to express that she is not happy, a few days ago Xu Ping teased her and said that the mirror was so bright and bright, she was going to urge Xu Ping to do it for her.

It was no longer the idle days in the grange before, and Xu Ping didn't have so much time to play with her. The real mirror uses ammonia and silver nitrate, which can be collected from the coking exhaust gas and then slowly purified, or directly collected by fermentation with human and animal excrement, but silver nitrate is very troublesome. The key is the preparation of nitric acid, the only feasible thing in this era is probably to use concentrated sulfuric acid and saltpeter distillation, concentrated sulfuric acid and use green alum or bile alum dry distillation, this process has been there since the Tang Dynasty, but Xu Ping has the time and mood to try step by step? He just teased Xiuxiu casually, and he wouldn't actually do it until everything was on track and he had time.

Mirrors are a good thing in the end, in this era, you can cheat money everywhere, and there is no reason not to make mirrors when glass is made, and money is like picking it up.

Tan Hu led people in, arranged for them to sit down, came over and lit a kerosene lamp, and put one on a table, which was as bright as daytime.

Tonight, it was the first time that Xu Ping had seriously met this group of Fujian immigrants.
