I was engaged in development in the Qin Dynasty

"This heated kang is good, can I take away the prescription so that the common people can have a good winter?" Zhao Zheng asked.

"Of course it's possible." Liu Ze naturally wouldn't refuse, he just mentioned a concept, the craftsmen on Zhao Zheng's village were the ones who really made the kang, Zhao Zheng wants it now, it's for the common people, what is he not willing to do? of. "However, you have to pay attention. If the kang has been burned for a long time, there will be carbon ash in it. After a few years, it may need to be refurbished. Otherwise, the soot in the kang will be ignited, and the quilt on the kang may be damaged. It will burn." Especially for ordinary people here, they use hay to make mattresses, so they should pay special attention.

"Don't worry about this. The materials used are not particularly expensive. It's just some mud. It's renovated once a year. I guess they are all happy." Zhao Zheng didn't care.

It’s no big deal to spend more effort, as long as it can keep warm, I don’t know how many people will freeze to death every winter. Although it is a year of auspicious snow, it is a good year for those who have to survive. A good year is not a good year.

When leaving, Zhao Zheng took Dashan and Dahe away, and by the way, he also took away his apprentices. As for the other people in Zhuangzi who did not have a heated kang, they could only wait for Dashan and Dahe to come back. After all, people in Zhuangzi spent the winter. The conditions are still good, compared with those whose families may only have one winter clothes, it is still much better, at least they can survive the winter.

After Dashan and Dahe were taken away by Zhao Zheng, they began to get busy, bringing their apprentices to each household, and it was not the big families in the capital who first made the kangs, but the poor people in the capital. , While feeding these people, they also have to lead the students. After the students have learned it, the students will start from the suburbs of Beijing and spread to the surrounding cities of Xianyang.

I don't know how long it will take to spread to the edge of the Qin State, but now that the transportation is not developed and the information is updated slowly, it is estimated that it will take several years to spread the kang technology throughout the Qin State.

Zhao Zheng learned that people in the capital accepted the kang well. However, there were some useless firewood. Most of the firewood in the capital was bought. If you want to keep the heat all day long, the stove cannot be extinguished. However, I really feel sorry for the firewood. I sleep at night. The time is right, after all, most people who freeze to death freeze to death while sleeping at night.

Hearing the feedback from people in the capital on the heated kang, Zhao Zheng expressed his satisfaction. However, let’s forget about this year. The cost of the heated kang was subsidized by him from the national treasury. The people paid their own money. Because of the matter of the heated kang, he was very concerned about Liu Ze's affairs. Therefore, he kept thinking about which family's noble daughter Liu Ze would like it. However, Zhao Zheng felt that he was not in a hurry and waited for his birthday. At that time, he allowed those ministers to bring their family members into the palace. At that time, he would see that the noble daughter of that family looked good, and then he would match Liu Ze.

For Zhao Zheng's thoughts, Liu Ze didn't know. He was more happy. With the heated kang, the wine he brewed could be easily fermented. Now that the weather is cold, the fermentation time is long, and the temperature is too high when placed on the stove. Now, it is placed on the kang, the stove is constantly burning, and the fermentation temperature is moderate. At first, Liu Ze was worried that he would not be able to catch up with Zhao Zheng's birthday, but now there is no need to worry.

Distilling alcohol is very simple. The boiling point of alcohol is different from that of water. The boiling point of alcohol is 78.5°C, while the boiling point of water is 100°C. Therefore, if the temperature is controlled between the two, the concentration will be higher. The more alcohol, the more times of distillation, the higher the concentration, and the higher the degree of alcohol.

At the beginning of the distillation, Liu Ze could not control the temperature well. After all, there was no thermometer. In the end, the temperature was controlled by the brewing craftsman. In this way, Liu Ze finally got a higher concentration of wine, and then with the help of the craftsman , Distilled it several times, and finally, Liu Ze tasted it, and it should be at [-] or [-] degrees, and there was no further distillation.

"This wine is really strong, and it scratches your throat after drinking it, but it tastes very mellow," the craftsman who was lucky enough to taste it in advance praised.

"Don't continue distilling when it's so strong, it will burn your throat any higher," Liu Ze reminded.

"Don't worry, we have recorded it," the craftsman promised quickly.

Liu Ze thought to himself, if the alcohol can be purified to more than 70%, it is actually possible. At that time, it will become medical alcohol, which is good for sterilization. However, he is not very clear about the level of surgeons in this world, and some dare not speak nonsense. After all, medical alcohol is not a panacea. Even if you use medical alcohol to clean the wound, there is still the possibility of infection, and the possibility of infection is still very high.However, when the time is right, he can still talk to Zhao Zheng.

Several hundred catties of glutinous rice, but in the end they only got more than 100 catties of distilled wine. Liu Ze was a little helpless. The loss rate was really good. This can’t be blamed on Liu Ze. It was a blind exploration. Liu Ze buried 20 catties of distilled wine under the peach tree. After a few years, the wine will become more mellow. He can bury some every year and take it out after [-] years. People who are good at wine must flock to.

When Zhao Zheng learned that Liuze wine was ready, he began to look forward to his birthday. The birthday gift that person gave him, but he made it himself. He said that they made the soup himself. He really thought he was a fool.

It was the twelfth lunar month in a blink of an eye, and the Chinese New Year was only a few days away. The Empress Dowager came to Xianyang from the Li Palace of Yongcheng with a long letter to celebrate the New Year with Zhao Zheng.

Since it is the New Year's Eve, it is natural for the family to be together, even the Qin royal family is no exception. The royal family celebrates the New Year, and all members of the royal family must be present, plus some useful ministers, such as Lu Buwei, and Lai Ai .

"This time Wang discovered the heated kang. Compared with previous years, this year, people in the suburbs of Beijing died of freezing to death as low as one floor. This time, the money allocated for disaster relief is still very effective. It is my responsibility to promote it. Great Qin's blessing," Lu Buwei praised.

Lai Ai sneered, "Lu Xiang just saw the suburbs of Beijing, and died of freezing in the distance. Compared with previous years, there is no improvement at all." What's the use, a king without rights is a toothless tiger. He controls the queen mother, and holds the queen mother firmly in his hands. Even the king of Qin has nothing to fear.

Why does Lu Buwei think highly of Lai Ai, she is just one of his disciples, he really thinks that if he climbs up to the queen mother, he will have no worries for the rest of his life, he is so naive, now that Qin Wangzheng has grown up, he has already stretched out his claws a few years ago , Now, the wings are almost full, and he also heard that this guy dared to call himself Qin Wangzheng's false father. Now that he is humiliated, Qin Wangzheng can bear it, but when Qin Wangzheng's wings are really full, today's humiliation, he Day, it will be returned.

Seeing Lu Buwei arguing with Lai Ai, Zhao Zheng didn't seem to hear it, and he didn't seem to notice the flirtation between the Queen Mother and Lai Ai at all. , it's better to go to Zhuangzi and ask that person to make him a meal of dumplings.
