[The second update. There is another update around twelve o'clock, which is today's third update. Tomorrow's first update, please read it tomorrow morning]

In the brand new oil lamp, the cotton wick is burning smoothly.

The light shining on the letter paper is no longer the shaking when using candles, but bright and stable. Compared with candles, the light is much stronger.

After watching under the lamp for a long time, your eyes will not be too sour. Compared to using candles and old-style oil lamps, reading time is a little longer.

Han Gang cares about his vision and his children's vision health. He does not want them to wear glasses early. The benefits of such oil lamps to protect their eyesight are self-evident.

This is a new type of oil lamp.

Outside the glass lampshade, there is a circle of copper frames as the shell protection. The oil pot below is also cast in brass, made by fine craftsmanship, and the pattern of wealth and honor are carved.

Compared with the kerosene lamps in later generations, there is only one less thing that can be adjusted directly outside. The wick can only be adjusted by opening the lampshade to control the brightness of the oil lamp.

However, compared with the structure of the glass lamp, the oil used is more meaningful.

The raw materials come from petroleum produced in Yanzhou and products obtained after distillation. However, the output is not large and the raw material output rate is also small. If the temperature cannot be measured, the heat can only be mastered through experience.

In Han Gang's eyes, such refining is even less technical than the native refining method in later generations. But he could not have any complaints about the lamp oil produced.

The daily lighting oil used for daily use has been transferred from bio-oil to mineral oil, which has been a great improvement.

However, only a small part of the products after refining can be used as lamp oil.

After oil refining, there will be asphalt that will soon solidify, as well as sticky and unignitable oil slurry that emits a pungent smell.

Under the advice of Hangang, asphalt is used on many roads in Beijing, and it is mainly used with cinders. Instead, it should be heavy oil slurry.

And before the lamp oil comes out, there is still a piece of waste oil.

This waste oil cannot be used as lamp oil. It will make the room smell like it. It cannot be placed in an oil lamp without a lampshade. When placed in an oil lamp with a glass lampshade, it may sometimes explode and blow up the oil lamp to pieces when ignited.

To eliminate the interference of this waste oil, one furnace must be refined before the second furnace can harvest the lamp oil. The whereabouts of the waste oil is to be poured into the jar and become a weapon when defending the city.

Of course, Han Gang knew what the waste oil mentioned in the letter was, but he couldn't think of how to use this oil in this era besides military purposes. Could it be that he could write back and add some sugar to the waste oil to make the turbulent tank more powerful? It can't be used as a cleaning agent? Speaking of which, I don't know if it can be used when making lacquerware.

Han Gang thought that after all, people would have to study it before they could know it. Maybe someone could write enough papers published in Nature.

As the preparations for postal and express subscriptions become increasingly deepened, Nature has also joined in. The new issue of Nature has already stated on the last page that it will be changed to a subscription-based distribution system in the future. Authors who are selected will receive free gifts from the next year for a year.

Han Gang borrowed people from two newspapers to help solve the subscription and subsequent delivery, and each sent a manager to deal with the distribution problem. When Nature was released, he borrowed the channels of the two newspapers, so the subscription and release naturally continued. Han Gang and Su Song had no intention of personally doing it.

More than 3,000 readers in the capital who are preparing to subscribe to "Nature" have registered at various sales offices. Whether they follow the trend or really like Qi, the study of studying things is really popular today.

Han Gang didn't know how many of them really wanted to study the study of things, and how many people would continue to be interested in it, but he believed that as long as he saw someone who could continuously gain from it, his future would inevitably be bright, and no matter how to twist and turns the road would not change the direction of progress.

Just like the distillation of oil, it greatly expands the distillation process originally limited to winemaking. With the guidance of theory and evidence, the development speed will only get faster and faster.

Feng Congyi mentioned in his letter that both oil refining and new oil lamps have little to do with Hangang. He just wanted to get the ink used for printing and distillation of oil, which was the result of a whim of a gas student in Yanzhou. The result was overjoyed.

In Feng Congyi's letter, in addition to mentioning a few new inventions, he also mentioned the big and small matters within the Yongqin Chamber of Commerce and the development of various industries since this year. In addition, he was Han Gang's parents.

In Feng Congyi's heart, the two elders were in good health and were in good spirits. Now living in the village, Han Qianliu had to go around the ground every day, and Han Ali also came to talk to each other. The two old Fengwengs and Lao Fengjun, celebrated their birthdays, and the state officials, county officials or their families had to support them. No one dared to let them get angry. Of course, they lived a comfortable life.

But Han Gang knew that he was over and was both over 60 years old. With the average life expectancy at this time, it is hard to say how much time there is. He is not from a wealthy family, and he can live a pampered life since childhood and has good health. The two elderly people worked hard for many years, and the root of the disease has long been lost, and they may suddenly attack at any time.

Han Gang was also in a dilemma. He could not give up everything and return to his hometown to support his parents. Han Qianliu and Han Ali were unwilling to come to Beijing to live, so he could only entrust Feng Congyi and his wife first, and in a few years, let Han Zhong, the oldest of his children, go back to take care of him. Han Gang's eldest son is not a material for studying, so it is better to stay in his hometown and stay in the door and learn how to take care of the family business. He would not have any other specialties like some children from the prime minister's family, except for the prodigal family.

Feng Congyi wrote many pages of his letter, and Han Gang flipped it one by one, and it could be filled with a book when bound.

After a long time, he put down his letter and closed his eyes.

Wang Yi just pushed the door and saw Han Gang raising his head, closing his eyes to rest.

"Official! Are you tired?" she asked hurriedly, coming over and gently hit Han Gang's shoulder, "Let's have a rest tonight. There are so many things in the court today, and I haven't seen him rest when I come back."

"It's okay." Han Gang opened his eyes, patted his little hand on his shoulder, and smiled and said, "It's not the year of a suburban sacrifice, it's not that much trouble. I didn't see how early I came back today? Last year, I couldn't close my eyes for several nights."

This year's Winter Solstice ceremony was not a formal suburban sacrifice, so it was not that troublesome.

After congratulations, the Taimiao used the scriptures of millet recommendation, and the priest held a sacrifice in the Circular Mound of the Southern Suburbs. When he came back, he reported to the emperor and worshiped the Supreme Emperor and the Supreme Empress Sheng'an, which was soon over.

Today, the rewards given to all officials and the three armies are far less than the expenses after sacrifice to heaven. The inadequate treasury will not be exhausted again.

"Didn't you say that you have been fighting for the past two days to see if you want to fire a magistrate at the grand dynasty meeting? The officials didn't fight with the people from Taichang Liyuan?"

The family members of the important officials in Beijing have always been well-informed, and Han Gang did not think it was different. "I am not in the two palaces, so I have been pushed over long ago."

The system of the court meeting was implemented for many years and often changed a little. This time, because artillery made the court's face in front of the envoys of the Liao Kingdom, it was valued by the queen.

Not only do we usually set fire cannons, this time, the Supreme Queen still believes that the empty cannons will help the court's prestige, so there will also be a smell of gunpowder at the court.

In response, the ritual officer of Taichang Liyuan objected several times, saying that it was not in line with the ancient etiquette. However, he insisted on his own opinions, and there was no shortage of people in the court to support her. Finally, he argued.

The Li family is like a lawsuit, even if the brothers discuss etiquette and law, they must argue about which is right and wrong in the etiquette system. Cheng Hao and Cheng Yi argued, and Zhang Zai and Zhang Jian also argued. Lu Dafang and Lu Dalin's brothers also argued in a row when they wrote the village agreement. They would never convince everyone.

Since we can't argue, in the eyes of the prime ministers, we should do things according to the preferences of the Supreme Queen. However, the ritual officials kept holding on and argued, causing chaos in the court.

Han Gang hid aside early in this meaningless quarrel and pushed them all to the two palaces. He absolutely did not want to get involved - although in his opinion, the group of ritual officials just wanted to show their presence.

It is not in line with ancient rituals. But during the grand court meeting, a set of dance programs in the court was a rule. When Han Gang had to wear heavy court uniforms and danced with his hands and feet, he always felt that this custom, which was at least mostly barbarian blood, was really stupid.

Wang Yi knew Han Gang's temper and did not value etiquette very much. It was completely inconsistent with his title as a great scholar in the world.

However, in Hangang's theory of Qi, the so-called etiquette is not limited to the etiquette system, but rather to the grammar, the national system, and the order of the upper and lower levels, which is much broader than simple etiquette. If most Confucians learn not from the "Three Rites", their views are mostly similar to Hangang - everyone is afraid of the trouble of red tape.

"By the way." Han Gang suddenly opened his eyes, "Have you paid all the money for the holidays?"

"It's all sent. It's all new money produced by officials. I just went to the gold and silver business yesterday to exchange it."

Han Gang nodded, and the new money was exchanged the day before, so that the Tokyo military and civilians could use the new money from today.

"What did the family say?" he asked.

"Everyone says that this time the money is well-cast and meticulous, it looks valuable. Not only do the family say it, but everyone else says it."

"That's good." Han Gang felt relieved.

After preparing for so long, he didn't want any twists and turns, he just hoped to succeed smoothly.

The Mint successfully issued new money, and next, there was nothing to worry about before the New Year.

Wang Shunchen can only wait for news. Maybe after spring begins, he will receive the order from the Privy Council. Japan also has to wait for Yang Congxian's news. But even if there is anything, he will have to wait for the matter next year before making any decisions.
