In April 187 A.D., the cold winter was coming to an end.

During the half-year winter, many poor people in Xuanwu County froze to death.

In this era, the cotton of the Han Dynasty was only in the Shanglin Garden, and there were hundreds of them as ornamental plants. A fur coat can keep you warm, but not many people can afford it. Poor people generally wear multiple layers of clothing to protect themselves from the cold.

Gongsun Kang wanted to promote the ondol. But the fire pit needs to burn coal, so the premise is to mine the coal first. I thought about it deeply, there are more trees than people in this era, and I don't have to worry about burning them all at all. Therefore, he led people to build a fire kang in the cottage and in the dock fort. Every day, a lot of firewood is burning. After the promotion, the poor people in Xuanfu County died a lot less every winter; There are many more woodcutters selling firewood, which can be regarded as a prosperous industry.

Gongsun Kang also taught the family members to make mud bricks and build earthen embryo houses in the cottage. Replace thatched houses with civil engineering structures.

Mix wet soil with hay and place it in a wooden frame; Then step on it repeatedly with your feet to make the soil solid; Finally, let it dry in the sun or air dry. When the mud is dry, remove the wooden frame. In this way, you can use a wooden frame to dry a piece of standard mud blocks of uniform size, which is used to build a house, which is equivalent to the role of red bricks.

This method was still used in rural China until 2000. It does keep you warm.

In order to reduce the freezing of some people in Liaodong, Gongsun Kang asked the family members to pass on this method to relatives and friends outside the cottage, and then let relatives and friends spread it widely.

Unexpectedly, the fire kang and adobe house also brought a lot of popularity and prestige to the Gongsun family.

The so-called Qin bricks and Han tiles, in this era, can already fire green bricks and gray tiles. However, the process is complex, the energy consumption is high, the output is small, the cost is high, and the ordinary people cannot afford to live, so it is of practical significance to vigorously promote adobe houses. In the future, when the conditions are ripe, craftsmen can also study the firing of low-cost red bricks and red tiles.

The families of the Han Dynasty were not simply landlords who could only annex land, they were the elite class of society with family education. At least the vast majority of talents are cultivated by the family.

Compared with money and power, family education is what keeps a family prosperous. Although the Gongsun family has declined, Gongsun Du is also a small official. But there is still homeschooling.

The family of the Gongsun family is shipbuilding. Didn't expect that, right? The Gongsun family is the inheritance of the Gongban or Luban. And the public loss class is a strongman who can fight in the ring with the Mo family, and in terms of Baigong KitKat, he is a generation of grandmasters.

The inheritance of the Gongsun family is a monopoly inheritance from technology to drawings, from material selection to craftsmen. In the entire Three Kingdoms era, there were only three families with a complete shipbuilding heritage: the Jiangdong Lu family, the Jingzhou Cai family, and the Liaodong Gongsun family. These three monopolized the shipbuilding industry of the Han Chinese.

After Gongsun Kang learned about this fact, he was shocked for many days. But it's okay to do this, the technology of the future generations in the memory can be copied through the handicraft workshop in the family. And the world will think that it is the inheritance of the public loss class of the hundred craftsmen KitKat, at most they think that the blue is better than the blue, and there will be no idea of monsters.

Of course, Gongsun Kang did not immediately change the world at first, he continued to study and practice martial arts. No matter how urgent he is, he will not propose any reforms, even the simplest of high wine.

When it comes to high-strength liquor, distillation is a simple matter. I didn't do it at first, in order to adapt to society and protect myself. But now he has made friends with his father, Gongsun Du, and his father has also accepted the statement of God. In order to reduce the mortality rate of wounded soldiers, it is necessary to get alcohol out.

During the thirty days of intense training of the soldiers, Gongsun Kang was not idle, he went down the mountain to pound high alcohol and alcohol in the dock fort. As a hot-blooded young man who often fantasized about traveling in his previous life, he had an in-depth understanding of alcohol, papermaking, printing, the improvement of waterwheels, the zigzag plow, the drying of salt, the manufacture of chairs, gunpowder, catapults, and so on.

After thinking deeply, Gongsun Kang didn't do it right away, he went to find his father.

"Father, the child was blessed with a dream last night. God gave a way to make liquor. "The god stick is out of control.

"God's bestowed? Liquor? Gongsun Du looked at Gongsun Kang suspiciously.

Gongsun Kang looked back at Gongsun Du firmly, without a little timidity. "Yes, Father. There is no second person in this world who can do alcohol. ”

There are too many things that I know, and I can only rely on God. And at present, he is already a steel and iron backbone, and he is not afraid of anyone secretly snatching it.

"I'll tell you more."

"Yes, father." Gongsun Kang explained in detail the production method of high-grade liquor, mainly distillation. In addition, the alcohol distilled repeatedly can be disinfected and healed, and is the best necessary wound medicine for soldiers on the battlefield; It is also a disinfection and prevention medicine for plague.

The origin of liquor is, of course, a gift from heaven. In the dream, there is a legend of a white-bearded immortal.

Gongsun Du doesn't care about this. What he cared about was what Gongsun Kang said in the end: the best healing medicine on the battlefield, the disinfection and prevention medicine of the plague.

This is a big killing weapon, and you must protect it in your own hands. And now that he has been dismissed, he only has a few hundred parts in his hands. There is no strength to protect at all. So it can't be mass-produced. It can only be produced in small quantities for its own use. Gongsun Du thought secretly.

"My son's alcohol must be kept in absolute secrecy. Can only be crafted in the Family Dock Workshop. I'll give you a few of your absolutely faithful craftsmen, and you can lead them to make a small amount. "Gongsun Du instructed Gongsun Kang.

"Obey his father's orders" Gongsun Kang felt that prudence was correct, which was why he came to his father.

Gongsun Kang leads the family of brewing craftsmen. First, two large sealed iron pots and lids are made. Then some three-meter-long wooden pipes were used to drain the lid of the pot to assemble a simple still, and the wooden pipes connected the two iron pots together. One of the large iron pots, set on the stove, poured in the brewed rice wine and sealed it, then increased the heat and brought to a boil. The evaporated liquor condenses along the wooden tube and flows into another large iron pot. What comes out of this is the first pot of liquor.

After repeated distillation, two pots of liquor and alcohol will come out. If you use several more large iron pots and take turns distilling, an assembly line operation will be formed.

Of course, this is the easiest and fastest way to make sake using existing rice. If you want to get high-quality wine, you need to start with the brewing. Gongsun Kang told the craftsmen about the production method of liquor in later generations, and let the craftsmen explore and improve it themselves. 1. Raw material crushing. 2. Ingredients. 3. Cooking gelatinization 4. Cooling 5. Stirring paste. 6. Fermentation in the cellar. 7. Steamed wine.

These craftsmen, whose whole family lives in the dock fort, have been the sons of the Gongsun family for several generations, and there is absolutely no problem with loyalty. Gongsun Kang was still not at ease, so he set aside a separate area for the craftsmen and their families to live in. At the same time, two system-produced armor soldiers were sent to take care of them on site.

After understanding his family's situation, he didn't trumpet any more papermaking and printing. At present, the conditions are not ripe, and even if they are created, it is not wealth but a scourge. After your own family dominates Liaodong, you can launch these things.
