At the end of May, even the wind seems to be filled with sweat, which doesn’t feel cool at all when blowing on people, but instead 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, and two personal servants served him to get on the horse. He drank a little too much and finally climbed up with a twist.

A servant looked at the road ahead, while the other led a horse and walked down the mountain along the path.

Shen Chengrong felt satisfied. Who said that it was not good to be honest? If he hadn't been honest, Xu Tong would have praised him? Although the name of Dong sounded a bit low-level, it was still at the same level as Tuxian. If he was in charge, he, the Zhidong, was better than the prefecture. As for the official position awarded by the court, it was a false reputation and he had no salary to pay him. Besides, he could be promoted again after doing it well.

He reached the foot of the mountain with a swaying wave, but Shin Chengrong felt strange. From the moment he left the door, he felt that there was something special. He cared about his heart, but there was nothing.

The sunset hanging slanted in Shen Chengrong's eyes made him feel a little confused. He turned his head involuntarily to hide from the dazzling sunshine.

The moment he turned his head, he saw a slender figure standing under a banyan tree on the slope, looking at him quietly. This was the first time he had seen him. His face was so strange, but so familiar, as if he was far away from the world, but he had been with him.

Shin Seung-rong's eyes were a little blurred, and two old tears couldn't help but burst out.

"Lord, what's wrong?"

The servant who was leading the horse saw Shin Seung-rong's body shaking immediately and asked hurriedly.

Shin Seung-rong shook his head vigorously, stabilized his body, and waved his hand: "It's okay, it's okay, let's go, it's too late. Let's go home quickly and go home--"

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

Which parent doesn't like smart children? That daughter was once the flesh of his heart. He really hoped that the child could live happily for the rest of his life. He promised the Huang family to be destined to be the fate of the local chiefs. The children of the local chiefs have been married in this way for many years, and no one can escape. When the child grew up, he found a good husband, and he never said anything about the child. The barbarians did not value the relationship between men and women as much as the Han people in the Central Plains. As long as the child is happy, it's better to say that a young official is a high-ranking family. Who would have thought that so many things happened later? He was a barbarian's small cave master, and he could not afford to offend either side. He was not alone. There were hundreds of families in the cave. How dare he acted with his will? Today, he could use him to beat Zhongzhou and use Zhongzhou or Wuli County to deal with him back then. He could only forget the child.

However, some things can never be forgotten.

Duan Yunjie watched Shen Chengrong's figure disappear into the weeds in the bamboo forest, and turned silently to her residence. Her mother had hugged and raised herself, but since she could remember, she had never seen her again, and she didn't even remember her at all. Everyone said that she was similar to her mother, but she still couldn't imagine the way that woman looked like.

What kind of woman is that? She was able to wait silently for more than ten years, waiting for the day of reunion in the future.

Duan Yunjie didn't know whether he had disappointed him when he saw Shen Chengrong. He only knew that after seeing this, his heart was completely calmed down. He was a child without a mother and depended on his father for his life.

Xiuxiu and Liu Xiaomei sat shoulder to shoulder by the pond beside the bamboo forest, reaching into the water with barefoot barefoot and talking endlessly. The fruit dismounted from the horse and slowly strolled and ate grass.

Seeing Duan Yunjie walking over with her head down, Xiuxiu said, "Sister Duan, where have you been? The official asked just now and wanted to talk to you!"

Duan Yunjie's thoughts were interrupted, and she raised her head and asked, "Oh, what are you asking me?"

"How can I know? The official doesn't tell me what happened!"

Xiuxiu tilted her head to look at Duan Yunjie. Seeing that he looked a little dazed, she continued, "Sister Duan, you look a little bad. Are you sick?"

Duan Yunjie forced a smile: "No, maybe I was so anxious just now. Then you guys continue playing here, I'll go find the official to see what's going on."

Watching Duan Yunjie leave, Xiuxiu shook her head at Liu Xiaomei beside her: "It's weird!"

After entering the door, Xu Ping was sitting idle in the shade in the yard. Duan Yunjie cheered up and saluted: "Listen to Xiuxiu, the official asked me if you have something to do?"

Xu Ping did not pay attention to Duan Yunjie's expression and said casually: "It's nothing, but you have used a lot of paper recently. I want to ask what books you print, and I haven't seen any businessmen from other places come."

"It turned out to be for this matter. Most of the printed items recently were "Tang Poems" and "Selected Works" and so on. They were not sold to customers from other places, but those new Fujian customers bought them to read them."

"Oh, they buy books?"

Xu Ping sat upright in surprise and looked at Duan Yunjie.

Duan Yunjie smiled and said, "Isn't that true? I didn't expect that there are many people who know literacy in them."

"Oh, so that's it, it's interesting." Xu Ping leaned back on the chair, pondered for a while, and looked up and found Duan Yunjie was still standing there, feeling a little embarrassed, "A little thing will make you come. - Go and do your business, there is nothing else."

Fujian Road has been promoting culture and education since the Qian family in Minyue. It was the most developed region of the Song Dynasty with Jiangxi next to it. There were many scholars, so the difficulty of the development test in some states was no less than that in the provincial test hall test.

Xu Ping forgot this. Before the Fujian immigrants came, hundreds of local farmers gathered together could not find a few people who read the word. Some people were not good at Chinese and didn’t know how much it took to promote various technologies. Unexpectedly, when these Fujianese came, there were so many scholars that could significantly increase the number of books printed. This was an unexpected surprise. Many times, the role of scholars is really irreplaceable.

After thinking for a while, Xu Ping called Tan Hu and told him to find Duan Fang, Gao Daquan and Huang Tianbiao, and to call the little immigrant leaders to his yard at night and ask them to talk to him if you have anything to do.

The immigrants arrived just in time for busy farming. Xu Ping was afraid of delaying the farming time and dared not to make trouble, so he asked them to roughly divide the group by himself. Duan Fang and Huang Tianbiao led the county officials to take them to work hard. Now that the season has passed, the rice has been planted, and sugarcane has been planted while growing. Anyway, it is only a little sugar produced later, and it is easier to plant it underground every year.

As the sky gradually became dark, Xiuxiu bent down at the door and looked at the seven or eight lamps placed 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 curled her lips: "I'm lying again, this is obviously an oil lamp!"

"You said it's an oil lamp or an oil lamp."

"Official, what oil is used here? Why is there no cigarette?"

"This is called kerosene. If the oil is light, of course there is no smoke."

"Why does the oil have no smoke when it is light? What is the kerosene being squeezed out?"

"Of course kerosene comes from coal, not squeezed, but steamed. Xiuxiu I'm very busy tonight. Don't ask here. If you have free time, please ask him if you have any questions?"

"I don't care about it either! By the way, this cover-forget it, I'll go out to play with Xiaomei Liu!"

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

In this era, there are already transparent glass products, but there are very few transparent glass products. Most of them are from overseas, and they are expensive things used by women like rose water. Han people are used to using ceramics, and the development of glass products has no motivation and cannot pretend to be 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 collect them specially.

In the past, Xu Ping had no motivation to burn glass, and he could not eat or wear it. He did not expect this to make money for himself. The huge farm in Zhongmu could not finish it. Until a few days ago, he used nearby coal to make coke. Although there was a lot of coal, the quality was not good. He could not make coke that could be used to make iron. He could only use a lower temperature to make steel charcoal, which was better than charcoal. In this way, the process of charcoal refining was accompanied by a large amount of coal tar. Xu Ping had a whim to distillate the coal tar and actually made kerosene. In fact, the reason why kerosene was called kerosene in his previous life was because it was first distilled from coal. However, after a few years of this technology, it became popular to make kerosene from oil, leaving only a few traces in his name.

If the oil is too complicated to use the technical route involved, Xu Ping really can't stand that spirit, but it is much easier to make kerosene from coal. It can be made with it after taking it a little during the coking process. Xu Ping will not let go of such a good thing.

Of course, kerosene lamps need to be made. The oil-filled part can be made of porcelain. The lamp mouth just happened to be made a few days ago, which was just right. But for windproof, a transparent lampshade is indispensable. It would be a pity to have a kerosene lamp with a paper-paste cover like before. Xu Ping turned his head and burned the glass.

There are many rivers nearby, and good quality glass sand is produced by the Yu River. Glauber's salt and limestone are also produced here, which are both materials for clarifying glass. Xu Ping also knows that adding lead to glass can improve transparency. For example, there is lead ore in He County, and all the materials are complete. Transparent glass can be made by trial bit by bit.

Today is the first time that the kerosene lamp is officially used. Xiuxiu was a little unhappy when she saw it. Xu Ping gave her any novel things before. She had so many outside this time, but she had never used them. She lay here and pestered Xu Ping to ask questions, just to express her unhappiness. A few days ago, Xu Ping said that the bright and bright mirror that Xu Ping said was so bright and bright, so she urged Xu Ping to make it for her.

It wasn't the idle days in the farm before, Xu Ping didn't have so much time to play with her. The real mirror had to use ammonia water and silver nitrate. Ammonia water could be collected from the coking waste gas and purified slowly, or directly fermented with human and animal excrement, but silver nitrate was very troublesome. The key was the preparation of nitric acid. The only feasible thing in this era was to use concentrated sulfuric acid and saltpeter to distillate concentrated sulfuric acid, and green alum or gall alum to dry distillate. This process has been available since the Tang Dynasty, but Xu Ping did not have time and mood to try it step by step? He just casually teased Xiuxiu, and had to wait until everything was on track before he could actually do it.

Mirrors are a good thing. In this era, you can cheat money everywhere. If you make glass, there is no reason not to make mirrors. Money is like picking up.

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