Xu Sanjiao saw Wu Kang giving face like this, and immediately smiled, pulled his arm and said, "Let's go in together." ”

Walking into the dilapidated courtyard gate, I saw the dilapidated mansion. There are two main rooms and one wing room, and the roof of the wing house is still rotten. Two five or six-year-old ladies squatted by the door of the hall, each holding a bowl of soup cakes, which were boiled noodles. When they saw strangers, they all bowed their heads stiffly.

After a while, an old man walked out, about forty years old, in good spirits and with a strong waist, followed by Xu Sanjiao and his wife. Wu Kang took two steps and greeted him respectfully: "Wu Er has seen my father-in-law, and I came to the door temporarily empty-handed, which made my uncle smile!" ”

"Erlang hurry up and be exempt", Xu Laozhang stepped forward quickly to help, quite flattered: "It's good that Erlang can come, you don't need to take anything!" San Lang is on an errand under you, and you have to ask Erlang to discipline him a lot. ”

After a few noisy words, Wu Kang stepped into the topic and said the purpose of the trip: "I want to build a kang at home, and I ask my husband to help." The construction period is relatively tight, and more craftsmen are needed, so please ask the old man to help Zhang Luo. I can pay 500 wages upfront, and 500 more when it's finished. ”

The Xu family was obviously stunned, stunned by the usual amount of money, they had been busy for a year, and they couldn't save consistently. Xu Sanjiao wanted to speak and stopped, and now he didn't have the right to speak. Old Master Xu pondered for a moment and said, "What is the fire kang that Erlang said? I've never heard of it, and I've never seen it, for fear of delaying Erlang's work! ”

Wu Kang was a little embarrassed, it seemed that the Tang Dynasty didn't have this thing, and he smiled at the moment: "It's my negligence, the structure of the fire kang is very simple, and the old man is definitely competent." Please move to my house, you will understand as soon as you say it! ”

The father and son of the Xu family didn't ask any more questions and followed Wu Kang to leave. Ruyan and Xiaocui saw the guests and immediately came over to say hello. After a greeting, Xu Sanjiao said "second sister-in-law", shouting like smoke and almost crying.

Wu Kang didn't say anything, took everyone to the west wing, pointed to the west wall of the road and explained: "Three feet away from the west wall, the blue brick wall is two feet high, and the partition is opened in the middle. The wing room is about three zhang long, and it is equally divided into six partitions. In the middle of the front of the partition, a small door is opened close to the ground, and the small door is one foot high and half a foot wide; On the wall behind the partition, a hole is opened to build a chimney. ”

Xu Laozhang thought about it and said, "Listen to Erlang's meaning, it is to build a stove." It's just nine at once, isn't it too much? ”

Wu Kang shook his head and nodded, and explained: "It's similar to the stove, except that there is no iron pot on it, just a bluestone slab." Then build half a foot high, pave a layer of loess, pave the loess with green bricks, cover the green bricks with wooden boards, and the kang is completed! ”

Uncle Wu stroked his goatee, his eyes were a little tangled, and he muttered for a moment and said: "There is no difficulty in the work, I'm afraid the money is not enough." We look for loess ourselves, green bricks, bluestone slabs, and wooden boards all need to be bought, and the money has always been insufficient to buy materials! ”

Wu Kang couldn't help but laugh and said: "My uncle misunderstood, it has always been just wages, and it definitely does not include materials." What needs to be bought, let the seller deliver it directly, such as cigarettes and check out with them... How much money do you have at home? ”

Ruyan said: "There are about thirteen guans left, early this morning, Cui Wulang sent someone to send ten guan, saying that it was to buy Langjun's "Thirty-six Strategies". What are the thirty-six plans, we don't seem to have them, right? ”

Wu Kang couldn't help but be stunned, Lao Cui was in Wuzhou, he casually mentioned it yesterday, and he came to the door today?

The so-called 36 strategies, which became a household name in later generations, are actually a summary of classic war examples. To put it mildly, it is cold rice and hot stir-fry. The term "Thirty-six Strategies" existed during the Northern and Southern Dynasties, much earlier than the time when the book was written.

"Thirty-six plans, go for the upper plan", from the Song Dynasty Huihong's "Cold Fasting Night Talk". As this sentence became more and more popular, some people collected group books and compiled "Thirty-six Strategies". No one knows when or by whom it was compiled.

A book sells ten, a sure way to make a profit! Why don't you copy a few copies, be a porter of ancient and modern literary masterpieces, and sell them to Cui Kaizi to make a fortune? If you think about it carefully, it seems that it can be carried completely, and there are only thirty-six plans!

Pursed his lips with self-deprecation, plagiarism is harder for a physical education teacher than making glass! It's better to cover the kang first, hatch the eggs into chicken babies, think of this and ask Uncle Xu: "How much can a plasterer get for a day's work?" ”

Mr. Xu replied: "I can't say for sure, generous people give five wen, misers give two wen, and ordinary people give three wen." ”

Wu Kang nodded and said, "My husband will find a few more helpers, five yuan per person per day, and one more meal at noon, I want to set up the kang as soon as possible." In addition, I also asked my husband to find a carpenter to build some wooden boxes, three feet long, two feet wide, and four inches high. ”

Mr. Xu replied and continued: "There are many plasterers and carpenters in our street, so there is no need to find people from outside. Since Jiro can trust me, I will take over this job, and then I will notify the craftsman first, go to buy materials together, and start work tomorrow. I promise Jiro that it will be completed in less than ten days! ”

"With the words of the old man, I am relieved", Wu Kang is very satisfied, this street is Crouching Tiger, Hidden Dragon, and the neighbors are all craftsmen. turned to Xu Sanjiao and said, "San Lang will go home for a while, I'll ask your sister-in-law to help clean up, and let's go back to the state government together." ”

personally sent the father and son of the Xu family out of the door, returned to the bedroom to change clothes and freshen up, helped him pull his hair in a bun like a cigarette, and said while combing his hair: "Lang Jun forgives slaves and slaves for talking too much, what a good house in the West Wing, why toss?" What is the ondol used for? ”

Wu Kang thought about it for a while, and said honestly: "The fire kang is actually a bed, a bed that can be heated by a fire. Every cold winter, poor families who do not have cotton clothes and animal skins to keep out the cold rely on the soil kang to survive the winter! If every family in the northern region is pankang, many people can freeze to death in winter. ”

Ruyan thought about it, but still didn't understand: "Maybe Lang Jun is right, but the winter in Wuzhou is not cold, and the extra bed and quilt will pass, so there is no need to go to great lengths to build a fire kang." Besides, just the three of us, we can't sleep in such a big bed! ”

Wu Kang gave a thumbs up and praised with a smile: "Yan'er is right, the fire kang is really useless in the Jiangnan region." However, our kang is not a sleeping man, but a sleeping chicken... Hatching chicks. In my hometown, a lot of electricity... Rural areas with insufficient heat use this soil method to hatch chicks. ”

"Hmph, Lang Jun coaxed the slave again", like a pout of his mouth to express dissatisfaction: "The old hen hugs the nest and warms the chicks, which has remained unchanged for thousands of years." Muzhou and Wuzhou are next to each other, although the slave family is lonely and unheard, they also know a little about Muzhou, I have never heard of a fire kang there, and I have never heard of a fire kang there to warm chickens! ”

"Muzhou is a hometown, not a hometown", Wu Kang was afraid that she would get to the bottom of it, so he changed the topic and said: "The core of hatching chicks is temperature, which is what we call heat." The calories of people are not as high as those of hens, so they cannot hatch chicks. If the heat of the kang reaches the needs of the chicks to break the shell, the chicks can be hatched without the need for a hen. ”

Wu Kang hesitated slightly, thought for a few seconds, and then said: "If our fire pit is fully firepowered, at least a thousand eggs will be hatched, and for the time being, it will be calculated according to the loss of 30%, and there will be seven white chickens." How much can you earn by excluding the twenty days of firewood money, the wages of the hired workers? ”

Ruyan said: "One penny for an egg, one penny for a chicken, and seven yuan for money." Excluding the wood, there are almost six pieces left. Hehe, if you follow what Lang Jun said, let's get rich! More than six times a month, more than seventy or eighty times a year! ”

Wu Kang smiled and said: "Smoke is less labor, and hiring workers also costs money, which is estimated to be more expensive than buying firewood!" ”

Ruyan smiled coquettishly, and said while pulling his hair in a bun: "A wise man must make a mistake in a thousand thoughts, Lang Jun didn't think it through!" Hatching chicks is our cash cow, of course, we can't hire outsiders, but we can't be learned by them. Let's go to the market to buy slaves and maids, let them hatch chicks, and ensure that nothing goes wrong! ”

Wu Kang didn't react for a while, and only nodded after a long time, almost forgetting that there were slaves in the Tang Dynasty. When I was a child, I watched a TV series, which seems to be called "Kunlun Slave", which is about the slaves of the Tang Dynasty. Their status was very low, and their masters killed them for no reason, and they only had to serve one year of hard labor. If they commit a crime, the master does not let the yamen deal with it, and kills them privately, and they only need to be punished with a hundred boards.

Wukang, who was born in the new era, is somewhat difficult to accept, but he is not too entangled, and each era has its own rules of the game. Thinking of this is like buying a slave by cigarette, and I start to think about the tricky, scalp-tinging core problem, how to measure and control the temperature.

Control it well, move a few pieces of ice to cool down when the temperature is high, and cover two layers of quilts when it is low. Temperature measurement is tricky, and there are thermometers in later generations, which can be bought for a few dollars, but where can Datang buy them? As the saying goes, it is difficult for a good woman to cook without rice. Don't say that you are a physical education teacher, even Galileo, who invented the thermometer, you have to be blind when you travel to Datang!

After thinking about it, there is only artificial feeling left. In later generations, there was a village doctor in the village, Aunt Gu, who had opened a clinic for more than 30 years, and had a special skill, and never used a thermometer to measure body temperature. Put your finger under the patient's armpit to know how many degrees you burn, which is as accurate as a thermometer, with an error of up to 0.1 degrees. To put it bluntly, practice makes perfect, and feeling other people's body temperature all day long is naturally extremely sensitive.

Thinking of this, a flash of inspiration flashed in his mind, and he asked Ruyan, who inserted the hosta: "I heard people say that our ancestors, during the Northern and Southern Dynasties, proposed to measure the heat under the armpit of people to determine whether the patient had a fever. The normal human armpit temperature is thirty-seven degrees, and the best temperature for hatching chicks is between thirty-eight and thirty-nine, which happens to be the temperature at which people have a fever, are we..."

Ruyan was stunned for a moment, and then grinned: "The slave understands, Lang Jun is too smart!" Lang Zhong often heals people, and his grasp of calories is much stronger than that of ordinary people. The slave will go out with Xiaocui to see if there is Langzhong in the slave book, and how much to buy. This is a double win, usually hatching chicks, and occasionally treating us! ”

Wu Kang nodded again and again, he didn't expect that in the Tang Dynasty, he could mix with a high-ranking private doctor. got up and tidied up in front of the mirror, lit his forehead like a cigarette and said, "I want to go back to the yamen, you guys should pay attention to safety when shopping." It doesn't matter if I can't find the slave Langzhong, I'll ask Cui Wu or someone else to help. There is one more thing, buy some paper and pencil and come back, I will dictate that you will take the pen, get the thirty-six plans out, and send them to Cui Wu tomorrow. ”

Ruyan smiled playfully, and said, "Obey the order of the Lang Jun, let's write a book tonight." ”

Wu Kang nodded her forehead again and left the house to find Xu Sanjiao. Absent-minded along the way, with a thermometer in my head. On the way, I passed by a jade shop, the one that was deceived by the scammer, and suddenly the mouth suddenly opened, and I thought of the possibility of making a thermometer.

In this era, there are only natural crystals that are transparent. Later generations like to watch science and education channels, those "archaeology" experts, once in the Tang Dynasty tombs, excavated exquisite crystal necklaces. This means that in the Tang Dynasty, there was the ability to punch holes in crystals. Let Boss Jade make holes in the crystal first, and then grind it into a thin stick, and then build a thermometer himself.

The basic idea is: buy or order a mini vase, insert the crystal tube into the cork, seal the mouth of the bottle and fill it with water. Using the principle of heat expansion and cold contraction, first put the vase in boiling water and mark the water level in the crystal tube, which is 100 degrees. It is then placed in an ice-water mixture and marked with a zero degree water level. Try to divide the scale as evenly as possible in the middle, and a simple thermometer will become.

The more I thought about it, the more feasible it became, so I turned around and walked into the jade shop. Boss Yu was very enthusiastic and personally served tea and poured water. Wu Kang got straight to the point, talked to him about the crystal tube method, asked him if he could make it, and said: Money is not a problem.

Boss Yu thought about it for a long time, and only said that he would do his best. He used to drill crystal necklaces, and the success rate was 55. If you wear a long hole, you have to have a large crystal, and the success rate is even lower. As for the crystal grinding tube, it is not a problem.

Wu Kang was very excited when he heard it, and let him rest assured that he would be bold and let go of it, and he would be responsible for all losses. After all, all scientific research requires funding.

Leaving the jade shop and continuing to return to the state office, I thought that before making a thermometer, I had to rely on people to feel the temperature, hoping that Ruyan could buy a slave Langzhong. Walking to the gate of the state office, he met a messenger who had been waiting for a long time, and Cui Wu sent a letter. Reward the messenger with a few tips, go back to the bad guard and greet his subordinates, go back to the office, close the door, and open the thick letter.

summarized at the beginning, and the four conditions he proposed were all approved by the Wuzhou bosses. can't help but open the way of Kaiyuan Tongbao, absolutely invincible.

The first is the preparation of the ice-making factory, and the second-generation soldiers are divided into two routes, one way to find a suitable ice-making site, and the other to find ice-making saltpeter. They are all smart people, and they would rather go to Muzhou, Kuizhou, Hangzhou and other places than buy saltpeter in Wuzhou, for fear of leaking the news.

Wu Kang said that he understands that saltpeter ice making is a layer of window paper, and there is no technical difficulty at all. He wrote back to Cui Wu, saying that he was the shopkeeper and that everything about ice making was represented by Ruyan. There is no need to mix this business, the scorpion is the only one, and if you have the goods, you don't have to worry about selling it, and you don't need to go out in person.

In the letter, he also suggested that the size and specifications should be unified and made into a ten-pound square ice cube, with a suggested retail price of 100 copper coins. I believe that well-off families in Wuzhou will flock to it. After all, scarcity is expensive, and if everything goes well, it is an absolute profiteering.

The second thing, the ten acres of land used to store fertilizer, has been selected, nine miles away from the south gate of Wuzhou, and the official road is convenient. Wu Kang is very satisfied with this, in October next year, the first empress Chen Shuozhen rebelled and will attack the north gate of Wuzhou, which will not affect the warehouse. At the same time, the construction of the warehouse courtyard wall has also started, and it is expected to be completed in 20 days.

The third thing is that the ox carts, large and small wooden barrels began to be built, and the second generation has almost all the carpenters, working overtime day and night shifts, and it is expected that the delivery will be about 20 days.

Fourth, it is a little regrettable that the leaders of Wuzhou agreed to build public toilets, but only approved 15, five fewer than the original plan; The leaders agreed to recruit the law enforcement team, but the limit was 30, which was half of the original plan. Agree to implement the copper penalty policy, punish littering, open defecation, and impose a copper penalty each time. But it is necessary to divide the account fifty-fifty yuan, and for every one hundred yuan fine, fifty yuan must be paid.

Wu Kang angrily scolded his mother directly, these bastards who have plucked their feathers, they don't pay a penny to the law enforcement team, and they also ask for an equal share, just eat and don't shit!

Secretly cursed for a quarter of an hour, came out of the office, and slapped the meeting to start. Everyone came to the conference room, and Wu Kang sat in the main seat, quite a bit of a change of time and space. The conference room was designed by him himself, the table was a conference table for later generations, and the chairs were for later generations of high chairs. Because of this conference room, the furniture at home has been delayed, and now I am still squatting on the ground to eat.

Raising his eyes and scanning the venue, there was no one in the penultimate position on the left, and after thinking about it slightly, Qian Shun Qian Shiro was absent. The boy was only eighteen years old, a few months younger than himself, but he was the father of two children. The corners of his mouth couldn't help but pull a smile, and asked Jiang Daniu next to him: "Has Qian Si asked for leave?" What's going on at home? ”

Jiang Daniu shook his head and looked at Tong Lin Tong Saburo. Tong San and Qian Si lived on the same street, the two families were on the wrong side, and when they saw everyone looking at them, they sneered with a bitter face: "The Qian family quarreled yesterday, his little lady was sick, and Sister-in-law Qian didn't go to get the medicine, and donated the money to Huang Xiangu." Qian Si beat Qian's sister-in-law and went to see a doctor for the little lady! ”

Wu Kang had a spectrum in his heart, and it was estimated that it was feudal superstition, so he pondered for a moment and said, "Wait a minute, discuss Huang Xiangu, I'll arrange the work first." It is imperative to clean up the garbage heap and dung heap in Wuzhou. There are three districts, and you are in a group of 10 people, each in charge. The first group is in charge of the North District, and the team leader is Jiang Dalang; The second group is in charge of the central district, and the team leader is Xu Sanlang; The third group is in charge of the southern district, and the group leader is Tong Saburo. After completing the mission, each group will be rewarded with three times! ”

The bad guys climaxed instantly, and each group of three times was divided into three hundred per person, and the salary for a year was not so much! There must be brave men under the so-called heavy reward, and they were very excited and began to slap their horses, thanking Wu Kang for his support. However, there are also reasonable people, Xu Sanjiao asked: "Dare to ask Wu Shuai, how to clean up the dung heap?" ”

Wu Kang said: "Twenty days later, there will be ox carts, wooden barrels, and hemp ropes, and ten carts per component. Because you can't afford to buy so many cows, you are responsible for looking for them, cows, scolding, and donkeys. Tell the driver to bring his own tools, put the dung and garbage in large wooden barrels, and send them to the warehouse nine miles south of the city, and send a cart for ten cents. The group that completes the task first will be rewarded with 500 copper coins! ”

The conference room exploded, and everyone's faces turned red with excitement, some exchanged ears, some grinned, and some slapped horses. When they quieted down, Wu Kang continued: "In the past twenty days, everyone must find livestock, don't delay Ben Shuai's plan... So that's the end of business, let's talk about Qian Si, what is Huang Xiangu? ”
